provided in each of consumables 50. Consumables 50 are placed or
replaced based on the inputs of the information on the consumables
by information read unit 30.
[0099] Controller 40 is configured to control the units of specimen
analyzer 100. Controller 40 includes, for example, a CPU and a
memory. Controller 40 does not permit manual input unit 20 to input
the information on the consumables, but permits information read
unit 30 to input the information on the consumables. To be more
specific, only information read unit 30 is permitted to input the
information on the consumables. Moreover, the analysis of the
specimen does not become ready if information read unit 30 does not
input the information on the consumables. Furthermore, the
information on the consumables is not received until the
information on the consumables is input with information read unit
30. This makes it possible to prevent a situation where the
information on the consumables is mistakenly inputted due to an
input mistake with manual input unit 20. Hence, it is possible to
appropriately manage consumables 50 such as a reagent. As a result,
input mistakes and inappropriate use of consumables 50 are
prevented, enabling appropriate consumable management. For example,
information read unit 30 is capable of reading even a code with
many digits fast and accurately compared to the inputting by manual
input unit 20.
[0100] Consumables 50 are consumables used for specimen analyzer
100. Consumables 50 include, for example, a reagent used for
specimen analyzer 100. Consumables 50 include, for example, a
reagent used for measurement of the specimen. Also, consumables 50
include a reagent used for the analysis. Moreover, consumables 50
include, for example, a reagent used for quality control of
specimen analyzer 100. Furthermore, consumables 50 include, for
example, a reagent used for cleaning of specimen analyzer 100.
[0101] Each of consumables 50 is provided with information record
section 51 which includes the information on the consumable.
Information record section 51 is attached to, for example, a
container of each consumable 50. Information record section 51
includes, for example, a one-dimensional or two-dimensional
barcode. Moreover, information record section 51 may be an RFID
tag. Furthermore, information record section 51 may be a sign being
a combination of characters, symbols, etc. It is possible to read
information record section 51 with information read unit 30. The
information which is possessed by information record section 51 and
is related to each consumable includes at least one of the type,
the expiration date, a lot number, and a serial number of the
consumable. In addition, the information on the consumables may
include information on the type of the analysis apparatus to be
used.
[0102] Controller 40 is configured to perform control such that the
process does not shift to the next one concerning placement or
replacement of consumables 50 unless the information on the
consumables is input with information read unit 30. This makes it
possible to advance the processing concerning the placement or
replacement of consumables 50 after inputting information to
determine whether or not consumables 50 are appropriate ones.
Hence, it is possible to reliably place or replace appropriate
consumables 50.
[0103] [Configuration Example of Specimen Analyzer]
[0104] With reference to FIG. 2 to FIG. 57, a configuration example
of specimen analyzer 100 is described.
[0105] (Overall Configuration)
[0106] In the example illustrated in FIG. 2, specimen 101 is blood
in specimen analyzer 100, and specimen analyzer 100 is a blood cell
counting apparatus. The blood cell counting apparatus is an
apparatus which counts the number of blood cells contained in a
predetermined volume of blood specimen. Analysis unit 120 analyzes
the number of blood cells and concentrations of the components
contained in the blood.
[0107] When specimen container 103 containing specimen 101 is set,
specimen analyzer 100 aspirates specimen 101 in specimen container
103 and analyzes the specimen. For example, a container in the
shape of a generally-used blood collection tube can be used as
specimen container 103. Specimen container 103 is, for example, a
vacuum blood collection tube capped with a rubber cap or an open
blood collection tube which has an opening. Specimen 101 to be
contained in specimen container 103 is, for example, whole blood of
a subject (human), and is added with an anticoagulant. The
necessary amount of added anticoagulant is, for example, 10 .mu.L
to 15 .mu.L inclusive.
[0108] Specimen analyzer 100 has apparatus body 110 which includes
analysis unit 120 for analyzing the specimen collected from the
subject, output unit 130 for outputting analysis results 102 of
analysis unit 120, and controller 140. Moreover, specimen analyzer
100 includes information read unit 150 connected to apparatus body
110. Further, specimen analyzer 100 is connected to various types
of consumables 104 used along with analysis operation for specimen
101.
[0109] Apparatus body 110 is a unit provided with analysis unit
120, output unit 130, etc. in a box-shaped housing. Apparatus body
110 is configured as a small blood cell counting apparatus which
can be a desktop one, including information read unit 150 and
consumables 104. Analysis unit 120 and controller 140 are built in
apparatus body 110.
[0110] Container set unit 111 is provided at a front and lower
portion of apparatus body 110. Container set unit 111 is configured
such that it is openable and closable from the front surface of
apparatus body 110 in the direction toward the user (see FIG. 3).
Using container set unit 111, specimen container 103 containing
specimen 101 is set in apparatus body 110.
[0111] In the example illustrated in FIG. 2, analysis unit 120 is
configured to analyze multiple analysis items. As an example, as
measurement items by analysis unit 120, the analysis items include
e.g. eight items: white blood cell count (WBC), red blood cell
count (RBC), hemoglobin concentration (HGB), hematocrit value
(HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin
(MCH), mean corpuscular hemoglobin concentration (MCHC), and
platelet count (PLT). As analysis items to be analyzed on the basis
of the analysis results of the measurement items, the analysis
items include e.g. nine items: WBC-small cell ratio (% Lymph),
WBC-middle cell ratio (% OtherWBC), WBC-large cell ratio (% Neut),
WBC-small cell count (# Lymph), WBC-middle cell count (# OtherWBC),
WBC-large cell ratio (# Neut), red blood cell distribution width
(RDW-SD and RDW-CV), mean platelet volume (MPV). In this example,
the number of analysis items of analysis unit 120 is 17.
[0112] Output unit 130 outputs various types of information on
specimen analyzer 100 to the user. In the example of FIG. 2, output
unit 130 includes display unit 131 and print unit 135. In the
example of FIG. 2, display unit 131 is an LCD (liquid crystal
display), and is disposed at a front and upper portion of apparatus
body 110. Display unit 131 displays information. In the example of
FIG. 2, print unit 135 is a thermal printer which prints on thermal
paper with use of heat, and is located on an upper surface of
apparatus body 110.
[0113] Moreover, specimen analyzer 100 includes manual input unit
132 which receives an input operation of the user. In the example
of FIG. 2, manual input unit 132 is a touch panel provided on
display unit 131. The user is allowed to input information and
perform various operations by touching the icons displayed on
display unit 131.
[0114] In the example of FIG. 2, information read unit 150 is
configured to read an information record section provided on each
of consumables 104, and to receive inputted information. To be more
specific, information read unit 150 is a read apparatus such as a
barcode reader, a two-dimensional code reader, and a camera. The
information record section is a barcode or a two-dimensional
code.
[0115] In the example of FIG. 2, inputting of information on
consumables 104 by manual input unit 132 is not permitted, but
inputting by information read unit 150 is permitted. Controller 140
determines whether to use consumables 104 based on information on
consumables 104 inputted by information read unit 150. To be more
specific, controller 140 allows use of consumables 104 if
information on consumables 104 inputted by information read unit
150 is registered on server 200.
[0116] Consumables 104 are consumed along with analysis operation
of specimen 101 by specimen analyzer 100. Consumables 104 contain
the reagent used for the analysis of specimen 101. In the example
of FIG. 2, used as consumables 104 are diluted solution container
104a containing a diluted solution for diluting specimen 101 and
hemolyzer container 104b containing a hemolyzer which hemolyzes
blood cells. Moreover, consumables 104 contain a cleaning agent for
cleaning specimen analyzer 100. In the example of FIG. 2, used as
consumable 104 is cleaning agent container 104c containing a
cleaning agent for cleaning a fluid circuit in the apparatus. Note
that the diluted solution is used for a cleaning process. The
cleaning agent contains a cleaning component such as a sodium
hypochlorite solution, and has more cleaning power than the diluted
solution. Cleaning with use of the cleaning agent is regularly
carried out each time a predetermined period elapses, e.g. one
week. Cleaning with use of the diluted solution is carried out more
frequently than the cleaning with use of the cleaning agent each
time the analysis of specimen 101 is performed, for example. The
information record sections provided on consumables 104 have
information on consumables 104 recorded therein. Information on
consumables 104 includes at least one of the type of consumable
104, expiration date, lot number, and serial number.
[0117] As an example, in the example of FIG. 2, "pocH-pack D
(manufactured by Sysmex Corporation, registered trademark)" is
preferably used as the diluted solution, "pocH-pack L (manufactured
by Sysmex Corporation, registered trademark)" is preferably used as
the hemolyzer, and "CELLCLEAN (manufactured by Sysmex Corporation,
registered trademark)" is preferably used as the cleaning
agent.
[0118] (Configuration of Each of Units of Specimen Analyzer)
[0119] In the example illustrated in FIG. 3, print unit 135 is
configured such that it can change the size of print sheet 136, and
is configured to print analysis results 102 on the same surface of
a single piece of print sheet 136. To be more specific, print unit
135 includes sheet set unit 135a which holds print sheet 136 which
is elongated, and changes the size of print sheet 136 by printing
on an area of print sheet 136 with an appropriate length depending
on the print amount. In the example of FIG. 3, set to sheet set
unit 135a is print sheet 136 which is roll paper being rolled
thermal paper which is elongated with a predetermined width. In
addition, print unit 135 includes print head 135b which heats print
sheet 136, and prints using print head 135b while forwarding rolled
print sheet 136 with a not-illustrated motor. Thus, print unit 135
prints on an area of print sheet 136 with an appropriate length
depending on the amount of information to be printed including
analysis results 102. The user cuts the printed sheet sent from
print unit 135 in an appropriate length, and acquires one sheet of
printed sheet on which analysis results 102 are printed.
[0120] Container set unit 111 includes adapter 112 for holding a
lower portion of specimen container 103. When open, container set
unit 111 is capable of holding specimen container 103 in an upright
state. Here, in addition to specimen container 103, it is possible
to set, to container set unit 111, a QC reagent container (not
illustrated) which contains a control specimen (hereinafter
referred to as QC reagent) for quality control and cleaning agent
container 104c.
[0121] Analysis unit 120 includes pipette 121 for aspirating
specimen 101 from specimen container 103 set to container set unit
111 and drive mechanism 122 for pipette 121. Moreover, analysis
unit 120 includes detector 123 for detecting components in specimen
101 and fluid circuit 124 for feeding liquid. Furthermore, analysis
unit 120 (see FIG. 4) includes a computer which has processor 141
and memory 142.
[0122] Pipette 121 is an aspiration tube for measuring the amount
of a liquid. Drive mechanism 122 includes linear mechanisms made up
of e.g. a guiderail, a motor, and a belt pulley mechanism, and
holds pipette 121. Pipette 121 is provided at a position above
specimen container 103 set in container set unit 111, and is
configured such that it can move in the up-down direction and in
the horizontal direction. Pipette 121 is connected to a syringe
pump provided in fluid circuit 124, and is capable of aspirating a
predetermined amount of specimen 101 contained in specimen
container 103. Pipette 121 is moved down from a position above
specimen container 103, enters the inside of specimen container
103, and is allowed to aspirate a predetermined amount of specimen
101 by fluid circuit 124. Moreover, pipette 121 is moved by drive
mechanism 122 to a position above a mixing chamber of fluid circuit
124 to be described later and to a position above container unit
123a of detector 123, and is allowed to aspirate and discharge
liquid by fluid circuit 124 at each of the positions. In the case
where the QC reagent container containing the QC reagent and the
cleaning agent container are set in container set unit 111, pipette
121 can also aspirate the QC reagent and the cleaning agent by
performing the same or similar operations.
[0123] Fluid circuit 124 includes e.g. a mixing chamber, a pressure
source, a syringe pump, a diluted solution, chambers for hemolyzer
and waste liquid, a cleaning Spitz for cleaning pipette 121,
various valves for switching liquid feed, and a sensor. Fluid
circuit 124 connects pipette 121 and detector 123 together in a
fluid manner via a flow path such as a liquid feed tube. Moreover,
fluid circuit 124 is connected in a fluid manner to external
connectors 124a provided on the back surface of apparatus body 110.
The number of external connectors 124a provided is three, which are
separately connected via connection tubes 105 to diluted solution
container 104a, hemolyzer container 104b, and waste liquid
container 106.
[0124] Fluid circuit 124 mixes a predetermined amount of specimen
101 aspirated by pipette 121 and a predetermined amount of diluted
solution in a mixing chamber to prepare an RBC/PLT measurement
specimen, which is a diluted specimen with a predetermined ratio.
In addition, fluid circuit 124 mixes a predetermined amount of
specimen 101, a predetermined amount of diluted solution, and a
predetermined amount of hemolyzer to prepare a WBC/HGB measurement
specimen which includes a mixed solution of blood specimen, diluted
solution, and hemolyzer.
[0125] Detector 123 is configured to measure the target components
in specimen 101 corresponding to the analysis items. In the example
of FIG. 3, detector 123 measures multiple items. In the example of
FIG. 3, detector 123 is configured to perform measurement in
accordance with multiple measurement principles depending on the
target components of the analysis items.
[0126] To be more specific, detector 123 performs RBC measurement
and PLT measurement using a sheath flow electrical resistance
method. Detector 123 performs WBC measurement using an electrical
resistance method. Detector 123 includes resistance detector 123b
for performing measurement using the sheath flow electrical
resistance method and the electrical resistance method. Moreover,
detector 123 performs HGB measurement using a colorimetric method.
Detector 123 includes optical detector 123c for performing
measurement using the colorimetric method.
[0127] The sheath flow electrical resistance method forms a sheath
flow of a specimen flow and a flow of sheath liquid surrounding the
specimen flow, and causes the sheath flow to pass through an
orifice. Electrodes are provided in front and rear of the orifice,
respectively, in the flow direction. A pulse signal, which
represents the presence and volume information of each blood cell,
is measured based on the change in resistance between the
electrodes generated by the blood cells passing through the
orifice.
[0128] Here, the diluted solution forms the flow of sheath liquid,
and the RBC/PLT measurement specimen forms the specimen flow.
Resistance detector 123b includes an orifice and a pair of
electrodes used for measurement. Analysis unit 120 obtains the red
blood cell count (RBC), the platelet count (PLT), and the
hematocrit value (HCT) from the measured count value of the pulse
signal.
[0129] The electrical resistance method causes the WBC/HGB
measurement specimen to pass through an orifice, and measures a
pulse signal which represents the presence and volume information
of each blood cell based on the change in resistance between the
front and rear electrodes of the orifice. Analysis unit 120 obtains
the white blood cell count (WBC) from the measured count value of
the pulse signal.
[0130] The colorimetric method causes a light source to emit
measurement light to the WBC/HGB measurement specimen, and detects
the measurement light having passed through the specimen with a
light receiving element. Additionally, the same process is also
performed on the diluted solution, and analysis unit 120 obtains
the hemoglobin concentration (HGB) based on the difference in
absorbance between the diluted solution and the WBC/HGB measurement
specimen. Optical detector 123c includes the light source and the
light receiving element used for measurement. The light source is,
for example, an LED, and the light receiving element is, for
example, a photodiode.
[0131] The mean corpuscular volume (MCV), the mean corpuscular
hemoglobin (MCH), and the mean corpuscular hemoglobin concentration
(MCHC) are calculated by analysis unit 120 from the measurement
values of the red blood cell count (RBC), the platelet count (PLT),
and the hematocrit value (HCT), respectively.
[0132] Based on the analysis results of the measurement items,
analysis unit 120 obtains the analysis items of the WBC-small cell
ratio (% Lymph), the WBC-middle cell ratio (% OtherWBC), the
WBC-large cell ratio (% Neut), the WBC-small cell count (# Lymph),
the WBC-middle cell count (# OtherWBC), the WBC-large cell ratio (#
Neut), the red blood cell distribution width (RDW-SD and RDW-CV),
the mean platelet volume (MPV).
[0133] As illustrated in FIG. 4, controller 140 includes processor
141 such as a CPU and memory 142. Memory 142 can include a volatile
memory such as a RAM, and a non-volatile memory such as a ROM, a
flash memory, and a hard disk. Memory 142 has, for example, a
control program for controlling specimen analyzer 100, analysis
program for obtaining analysis results 102, and display screen data
of display unit 131 recorded therein. Processor 141 executes a
program recorded in memory 142 and thereby functions as controller
140 which performs operation control of units such as drive
mechanism 122, fluid circuit 124, detector 123, display unit 131,
and print unit 135. Moreover, processor 141 functions as part of
analysis unit 120 which obtains analysis results 102 of the
analysis items by executing the programs recorded in memory 142.
Controller 140 and analysis unit 120 may be configured as a
separate processor and memory. Furthermore, controller 140 obtains
information inputted through manual input unit 132 and processes
that information. What is more, controller 140 controls read
operation by information read unit 150 through an external IF, and
processes the read information. Still further, controller 140 is
capable of connecting to network 250 via communication unit 145,
and thus accessing management server 200 of specimen analyzer 100.
Communication unit 145 includes a communication interface, and
establishes cabled or wireless connection to network 250.
Communication unit 145 connects to network 250 via, for example, an
Ethernet cable.
[0134] Controller 140 is configured to perform control of causing
display unit 131 to display how to input information on
consumables. This makes it possible to input the information on the
consumables in accordance with the display of display unit 131,
facilitating input operation without mistakes. More specifically,
controller 140 is configured to perform control of causing display
unit 131 to display an instruction prompting to input the
information on the consumables with information read unit 150. This
makes it possible to guide a user to read the information on the
consumables with information read unit 150. Hence, the user can
easily input the information on the consumables.
[0135] In addition, controller 140 is configured to perform control
of causing display unit 131 to display a message based on a
determination as to whether or not inputted information is
appropriate. This makes it possible to prevent use of inappropriate
consumable 104 because information on the inappropriateness is
displayed as a message if consumable 104 is inappropriate. Also, it
is possible to prompt to use the appropriate consumable by
displaying the reason for inappropriateness. For example,
controller 140 is configured to perform control of acquiring an
expiration date of a consumable based on information on the
consumable, and causing display unit 131 to display a message based
on a determination as to whether or not the expiration date has
passed. This makes it possible to prevent use of expired consumable
104, which can prompt to use a more appropriate consumable.
[0136] Also, consumables 104 include a disposable consumable. For
example, a cleaning agent for cleaning the inside of specimen
analyzer 100 is a disposable consumable 104. If an information
record section of disposable consumable 104 is read again after use
of the disposable consumable, controller 140 is configured to
perform control of not permitting use of consumable 140, and
causing display unit 131 to display an error message. This makes it
possible to prevent a situation where disposable consumable 104 is
used again, which can prompt to use a more appropriate
consumable.
[0137] Furthermore, controller 40 is configured to perform control
of acquiring whether or not consumable 104 is usable based on
information on the consumable, and causing display unit 131 to
display an error message in a case where consumable 104 is
unusable. For example, controller 140 is configured to perform
control of acquiring a type of consumable 104 based on information
on the consumable, and causing display unit 131 to display an error
message in a case where the type of consumable 104 is different.
This makes it possible to prevent a situation where consumable 104
of different types is set and used.
[0138] In addition, controller 140 is configured to perform control
of causing communication unit 145 to transmit information on
consumables inputted with information read unit 150 to server 200.
This makes it possible to manage consumables 140 with external
server 200, enabling more appropriate and easier management of
consumables 140. For example, controller 140 does not permit
inputting of information on a consumable when it is impossible to
connect to server 200 via communication unit 145. This makes it
possible to reliably manage consumables 104 with external server
200 because placement or replacement of consumables 104 is not
allowed when it is impossible to connect to server 200.
[0139] In other words, communication unit 145 can transmit the
information on the consumable inputted with information read unit
150, which works as an input unit, to external server 200.
Controller 140 is configured to allow analysis unit 120 to analyze
a specimen if connection is established between server 200 and
communication unit 145. This makes it possible to manage consumable
50 with external server 200, enabling more appropriate and easier
management of consumables 104 such as reagents.
[0140] Also, controller 140 is configured to permit use of
consumable 104 if the information on the consumable inputted with
information read unit 150 is registered in server 200. This makes
it possible to effectively prevent use of inappropriate consumable
104. More specifically, controller 140 is configured to permit use
of consumable 104 if a lot number as the information on the
consumable is registered in server 200. This makes it possible to
more easily manage consumable 104 by managing the lot number of
consumable 104 with server 200.
[0141] In addition, controller 140 does not shift to a next process
concerning placement or replacement of consumable 104 unless the
information on the consumable is input with information read unit
150. This makes it possible to advance the processing concerning
the placement or replacement of consumable 104 after inputting
information to determine whether or not consumable 104 is an
appropriate one. Hence, it is possible to reliably place or replace
appropriate consumable 104. For example, controller 140 is
configured to perform control of causing display unit 131 not to
shift a screen of display unit 131 concerning placement or
replacement of consumable 104 to a next screen unless the
information on the consumable is input with information read unit
150. This makes it possible to effectively prevent placement or
replacement of inappropriate consumable 104 because a screen to
advance placement or replacement of consumable 104 is not displayed
until the information on the consumable is input with information
read unit 150.
[0142] (Description on Server)
[0143] Registered with storage unit 210 of server 200 are serial
numbers of individual specimen analyzers 100. To be more specific,
the user is allowed to use only specimen analyzers 100 registered
with server 200. Registered with storage unit 220 of server 200 are
lot numbers and serial numbers of reagents. To be more specific,
the user is allowed to use only the reagents registered with server
200 in specimen analyzer 100. Moreover, stored in storage unit 220
of server 200 is information on a QC reagent. Information on a QC
reagent is stored associated with the lot number of that QC
reagent. To be more specific, information on a QC reagent includes
information on a measurement range of the QC reagent. For example,
QC reagents used include a High QC reagent containing a highly
concentrated component, a Normal QC reagent containing a normally
concentrated component, and a Low QC reagent containing a low
concentrated component. A normal value of the measurement result is
set for each QC reagent depending on High, Normal, and Low.
Moreover, the QC reagent has a varying normal value depending on
the lot. In light of this, storage unit 220 of server 200 stores
ranges of normal values in the case of measuring QC reagents
depending on the types High, Normal, and Low, and the lot
number.
[0144] [Operation Example of Specimen Analyzer]
[0145] With reference to FIG. 5, an operation example of specimen
analyzer 100 is described.
[0146] When the power is turned ON at step S10, a startup process
is performed at step S11. To be more specific, the system is
automatically checked. Also, the inside of the apparatus is
automatically cleaned. Additionally, blank check is performed.
[0147] At step S12, quality control is executed. The quality
control is performed at predetermined intervals. Display unit 131
displays a screen requiring quality control at predetermined
intervals. The user inputs data concerning quality control in
accordance with what is being displayed, and instructs to measure
quality control substances.
[0148] At step S13, a patient sample as a specimen is measured.
Display unit 131 displays a screen of an instruction for sample
measurement. The user performs sample measurement instruction in
accordance with what is being displayed. At step S14, the
measurement results are printed. To be more specific, the measured
and analyzed results are printed and outputted from print unit 135.
Note that display unit 131 does not display the measurement
results.
[0149] [Description on Sample Measurement Process]
[0150] With reference to FIG. 6, an example of a sample measurement
process by specimen analyzer 100 is described. In the example
illustrated in FIG. 6, specimen analyzer 100 measures and analyzes
the sample of a patient as a specimen.
[0151] At step S20, a sample container is checked. To be more
specific, display unit 131 displays images of the types of sample
containers available. The user checks the sample container by
comparing the images and the actual sample container. At step S21,
an operator ID is inputted. To be more specific, the user inputs an
ID for identifying the operator in accordance with the instructions
of display unit 131.
[0152] At step S22, a patient ID is inputted. To be more specific,
the user inputs an ID for identifying the patient in accordance
with the instructions of display unit 131. At step S23, the date of
birth of the patient is inputted. To be more specific, the user
inputs the date of birth of the patient being the sample to be
measured in accordance with the instructions of display unit
131.
[0153] At step S24, a measurement pre-treatment is performed. To be
more specific, display unit 131 displays the instructions on the
pre-treatment. The user performs the pre-treatment such as heating
and stirring of the sample in accordance with the instructions of
display unit 131. At step S25, a sample container is set. To be
more specific, display unit 131 displays the instructions on the
setting of the sample container. The user sets the sample container
in specimen analyzer 100 in accordance with the instructions of
display unit 131.
[0154] At step S26, the sample is measured. When the measurement of
the sample finishes, measurement results are printed at step S27.

[0279] (Outputting of Analysis Results)
[0280] In the example illustrated in FIG. 2, analysis unit 120
perform analysis on seventeen analysis items in total, eight
measurement items plus nine analysis items, as described above. In
the embodiment, controller 140 performs control of causing print
unit 135 to print analysis results 102, and prohibiting display
unit 131 from displaying analysis results 102. Thus, as a result of
analysis operations of specimen analyzer 100, the user obtains
printed sheet 300 being print sheet 136 on which analysis results
102 are written, as illustrated in FIG. 49.
[0281] In the example of FIG. 49, printed on printed sheet 300 are
facility information 301, apparatus information 302, date
information 303, operator information 304, subject information 305,
subject attribute information 306, result displaying section 307,
message section 308, and reference value information 309. Note that
although printed sheet 300 is separated for convenience in FIG. 49,
the separated portions are actually connected, and printed sheet
300 is one piece of print sheet 136 on which printing has been
performed.
[0282] Facility information 301 includes information on the name
and the address of the facility such as a hospital where specimen
analyzer 100 is installed.
[0283] Apparatus information 302 is information for identifying
specimen analyzer 100 which performed analysis. Apparatus
information 302 includes, for example, the model, the name, and the
serial number of the apparatus.
[0284] Date information 303 is information for identifying the time
point at which analysis was performed. Date information 303
includes the analysis date. In FIG. 49, date information 303
includes the analysis time in addition to the analysis date.
[0285] Operator information 304 is ID information for identifying
the operator who operated specimen analyzer 100. Operator
information 304 is not particularly limited, and is represented by
three alphabetical letters, for example.
[0286] Subject information 305 is ID information for identifying
the subject from which specimen 101 is collected. Subject
information 305 is represented by a seven-digit number, for
example.
[0287] Subject attribute information 306 is information on the
subject from which specimen 101 is collected, and shows the
characteristics and nature of the subject. Preferable as subject
attribute information 306 is information useful for diagnosis based
on analysis results 102. Subject attribute information 306 includes
at least one of the date of birth, age, and sex, for example. It is
possible to grasp the age of the subject using the date of birth.
Subject attribute information 306 may be an age, or information on
the corresponding one of the age sections. There is a case where
the criteria for diagnosis based on analysis results 102 differ
depending on the sex, in addition to the age. Hence, subject
attribute information 306 may include sex. Furthermore, subject
attribute information 306 may include body information such as the
height and the weight of the subject.
[0288] Result displaying section 307 is an area where analysis
results 102 are printed. Analysis results 102 include numerical
information 102a. In addition, if analysis results 102 include an
error, analysis results 102 include information 102b indicating the
type of the abnormality. As illustrated in FIG. 49, regarding
multiple analysis items, print unit 135 prints analysis results 102
for each of the analysis items. Regarding each analysis item, one
line of result displaying section 307 is assigned one item. To be
more specific, in each analysis item of result displaying section
307, the item name, numerical information 102a, and information
102b indicating the type of the abnormality (flag) are displayed in
sequential order from left.
[0289] Information 102b indicating the type of the abnormality is
printed to notify the user of the type of the abnormality when one
or more of analysis results 102 are outside normal range, or when
there is a predetermined analysis result error. If analysis results
102 include an abnormal value, controller 140 prints information
102b indicating the type of the abnormality as analysis results
102. Determination as to whether or not the results are normal or
erroneous is made based on the numerical ranges for analysis result
determination.
[0290] In the example of FIG. 50, for example, as information 102b
indicating the type of the abnormality, print unit 135 prints
information 102b indicating the type of the abnormality if analysis
results 102 includes an abnormal value. Information 102b indicating
the content of the error includes information 314 indicating a
first error showing that numerical information 102a is included in
a first erroneous ranges 372 (see FIG. 53), and information 315
indicating a second error showing that numerical information 102a
is included in a second erroneous ranges 373 (see FIG. 53).
Information 314 indicating a first error can include an indicator
indicating a high value (High) and an indicator indicating a low
value (Low) for each of analysis results 102. Information 315
indicating a second error can include an indicator indicating an
erroneously high value (ALERT H) and an indicator indicating an
erroneously low value (ALERT L), for example.
[0291] If a certain abnormal value included in analysis results 102
is included in a preset predetermined numerical range, controller
140 excludes the predetermined abnormal value in analysis result
102 from the content to be printed. An embodiment of displaying
result displaying section 307 is described later.
[0292] In FIG. 49, displayed in message section 308 is a
predetermined message to the user in a predetermined case. The
predetermined message includes message 311 prompting further
testing. Furthermore, the predetermined message includes, for
example, message 312 recommending the user to act immediately. If
analysis results 102 have no particular problem, no message is
displayed in message section 308.
[0293] The intention of reference value information 309 is to
provide information for evaluating analysis results 102 to the
user. Thus, in addition to analysis results 102, print unit 135
prints reference value information 309 to evaluate analysis results
102. Analysis result 102 of each analysis item has a numerical
range considered a normal range. Reference value information 309 of
FIG. 49 is information on numerical ranges indicating normal ranges
371 of analysis results 102. Here, the normal range for each
analysis item differs depending on subject attribute information
306 such as the age of the subject. In light of this, in FIG. 49,
reference value information 309 possesses several types depending
on subject attribute information 306 on the subject from which
specimen 101 is collected. Print unit 135 prints: subject attribute
information 306: and reference value information 309 corresponding
to subject attribute information 306 out of several types of
reference value information 309.
[0294] As described above, in the example of FIG. 49, in addition
to analysis results 102, print unit 135 prints the analysis date,
operator information 304 on the operator who performed analysis,
and subject attribute information 306 on the subject from which the
specimen is collected.
[0295] The information above is printed on the same surface of a
single piece of print sheet 136. To be more specific, print unit
135 prints analysis results 102, subject attribute information 306,
reference value information 309, and the predetermined message, if
necessary, on the same surface of a single piece of print sheet
136. In the example of FIG. 49, all information to be printed is
printed on the same surface of a single piece of print sheet
136.
[0296] (Output Rules and Display Embodiment of Analysis Results on
Printed Sheet)
[0297] Subsequently, output rules and a display embodiment in
result displaying section 307 of printed sheet 300 are
described.
[0298] Controller 140 determines whether or not analysis results
102 can be outputted depending on numerical information 102a as
analysis results 102. If numerical information 102a falls within a
predetermined range, controller 140 prohibits outputting of
numerical information 102a to printed sheet 300. Memory 142 of
controller 140 stores data of numerical ranges for analysis result
determination (see FIG. 53 to FIG. 55).
[0299] <First Determination Ranges>
[0300] As illustrated in FIG. 51, out of numerical information 102a
as analysis results 102 of analysis unit 120, controller 140
performs control of prohibiting the outputting of numerical
information 102a outside first determination ranges relating to
reliability of analysis.
[0301] FIG. 52 illustrates an example of first determination ranges
350. First determination ranges 350 (see FIG. 52) are each a
numerical range considered reliable enough for analysis itself by
analysis unit 120. First determination ranges 350 are each a
numerical range which surely has reproducibility, accuracy,
linearity, etc. of analysis results 102 of specimen analyzer 100
within a predetermined range, and is a numerical range set as the
specifications of specimen analyzer 100.
[0302] In the example of FIG. 52, first determination ranges 350
are each a linearity guarantee range for specimen analyzer 100. To
be more specific, analysis unit 120 outputs analysis results
proportional to the number and the concentration of the target
components in specimen 101. Here, the linearity guarantee range is
a range where the analysis results match the line of
proportionality within a predetermined error range. In other words,
the linearity guarantee range may be referred to as a measurable
range for analysis unit 120. Out of the analysis items, first
determination ranges 350 are set for five measurement items, WBC,
RBC, HGB, HCT, and PLT, which are measured by detector 123.
Regarding the measurement items, when numerical information 102a
outside the numerical ranges illustrated in FIG. 52 is obtained as
analysis results 102, controller 140 prohibits the outputting of
numerical information 102a as a measurement error.
[0303] In the example of FIG. 51, even in the case of numerical
information 102a within first determination ranges 350, controller
140 performs control of prohibiting outputting when numerical
information 102a includes a predetermined abnormal value. Regarding
numerical information 102a within first determination ranges 350,
controller 140 prohibits outputting when the information is within
second determination ranges 360 indicating a predetermined error of
the specimen, and performs control of permitting outputting when
the information is outside second determination ranges 360.
[0304] First, regarding numerical information 102a within first
determination ranges 350, analysis unit 120 performs analysis based
on the numerical ranges for analysis result determination
illustrated in FIG. 53 to FIG. 55. To be more specific, first
determination ranges 350 include normal ranges (reference ranges)
371 indicating normal values, first erroneous ranges 372 wider than
corresponding normal ranges 371, and second erroneous ranges 373
wider than first erroneous ranges 372. In the embodiment, second
determination ranges 360 are set as second erroneous ranges
373.
[0305] <Normal Range>
[0306] Controller 140 outputs analysis results 102 included in
normal ranges 371 illustrated in FIG. 53 to FIG. 55. In the example
of printed sheet 300 illustrated in FIG. 50, for instance, the
value of MCH (29.8 [pg]) falls within the normal range of an adult
(see FIG. 55), and numerical information 102a is printed as it is.
If analysis results 102 are included in normal ranges 371, this
means there is no error. Thus, information 102b indicating the type
of the abnormality for the analysis items is not printed.
[0307] As illustrated in FIG. 53 to FIG. 55, first erroneous ranges
372 include ranges of low value (Low) and ranges of high value
(High). Second erroneous ranges 373 include ranges of erroneously
low value (ALERT LOW) and ranges of erroneously high value (ALERT
HIGH). To be more specific, first erroneous ranges 372 are ranges
indicating minor errors near normal ranges 371, and second
erroneous ranges 373 are ranges indicating significant errors
further deviating from first erroneous ranges 372.
[0308] <First Erroneous Range>
[0309] In the example of FIG. 51, in the initial test, controller
140 prohibits the outputting of printed sheet 300 if numerical
information 102a is included in first erroneous ranges 372. To be
more specific, if numerical information 102a is included in first
erroneous ranges 372, controller 140 does not output printed sheet
300 but causes the user to perform retest on same specimen 101
using abnormal value notification screen P156 for notifying that an
abnormal value is included. Thus, in the initial test, all analysis
results 102 are prohibited from being outputted if numerical
information 102a is included in first erroneous ranges 372.
[0310] Controller 140 causes printed sheet 300 to output analysis
results 102 obtained in retest. If initial analysis results 102
match retested analysis results 102, controller 140 causes print
unit 135 to print analysis results 102, and if initial analysis
results 102 do not match retested analysis results 102, controller
140 prohibits the printing of mismatched analysis results 102. To
be more specific, if numerical information 102a of retest is
included in first erroneous ranges 372 and if determination results
of numerical information 102a match those of the initial test,
controller 140 permits the outputting of that numerical information
102a, and outputs information indicating the type of the
abnormality. For example, if numerical information 102a of the
initial test is included in the range of "Low" and if numerical
information 102a of retest is included in the range of "Low" as
well, the controller outputs information 314 indicating a first
error where numerical information 102a is included in first
erroneous ranges 372, together with numerical information 102a.
[0311] In the example of printed sheet 300 illustrated in FIG. 50,
the value of MCV (81.6 [fL]) corresponds to a low value (see FIG.
55) of an adult, and "Low" information 314 indicating a first error
is printed together with analysis results. Note that if the
analysis result corresponds to a high value, "High" is printed as
information 314 indicating a first error.
[0312] If numerical information 102a of retest is included in first
erroneous ranges 372 and if determination results of numerical
information 102a do not match those of the initial test, controller
140 prohibits the outputting of that numerical information 102a,
and outputs information indicating the type of the abnormality. For
example, if numerical information 102a of the initial test is
included in the range of "Low" and if numerical information 102a of
retest is included in the range of "High," the controller prohibits
the outputting of numerical information 102a. In this case, as the
analysis items, information 314 indicating a first error is
printed.
[0313] <Second Erroneous Range>
[0314] In the example of FIG. 51, out of numerical information 102a
included in second erroneous ranges 373, controller 140 prohibits
the outputting of numerical information 102a within second
determination ranges 360, and permits the outputting of numerical
information 102a outside second determination ranges 360. If
numerical information 102a is included in second erroneous ranges
373, controller 140 outputs information 102b indicating the type of
the abnormality. To be more specific, as has been illustrated in
FIG. 50, controller 140 displays an indicator indicating an
erroneously high value (ALERT H) or an indicator indicating an
erroneously low value (ALERT L) as information 315 indicating a
second error where numerical information 102a is included in second
erroneous ranges 373.
[0315] Second determination ranges 360 are each a range of abnormal
value presenting the possibility of having a predetermined serious
disease. Possible predetermined serious diseases in the blood cell
counting apparatus include, for example, leukemia, aplastic anemia,
myelodysplastic syndromes, paroxysmal nocturnal hemoglobinuria,
systemic lupus erythematosus, malignant lymphoma, disseminated
intravascular coagulation, thrombotic thrombocytopenic purpura,
hypersplenism, megaloblastic anemia, sepsis, tuberculosis,
sarcoidosis, hemangioma, infectious diseases, and congenital
thrombocytopenia.
[0316] Each of second determination ranges 360 is set as at least
part of corresponding one of second erroneous ranges 373. Each of
second determination ranges 360 is set within a range satisfying
corresponding one of first determination ranges 350 and within a
range of predetermined erroneously low value.
[0317] In the example of FIG. 53 to FIG. 55, each of second
determination ranges 360 is set within a range of erroneously low
value (ALERT LOW) of corresponding one of second erroneous ranges
373 set for at least one analysis item of white blood cell count
(WBC), hemoglobin concentration (HGB), hematocrit value (HCT), and
platelet count (PLT). In FIG. 53 to FIG. 55, the range of
erroneously low value (ALERT L) of each of white blood cell count,
hemoglobin concentration, hematocrit value, and platelet count is
set as corresponding one of second determination ranges 360.
[0318] Thus, if numerical information 102a is included in a range
of erroneously low value (ALERT L), controller 140 prohibits the
outputting of numerical information 102a. If there is numerical
information 102a within second determination ranges 360, controller
140 causes output unit 130 to output information 102b indicating
the type of the abnormality. To be more specific, if numerical
information 102a is included in a range of erroneously low value
(ALERT L), controller 140 prints information 315 indicating a
second error (ALERT L) being an erroneously low value.
[0319] If numerical information 102a is included in a range of
erroneously high value (ALERT H), controller 140 permits the
outputting of numerical information 102a. If numerical information
102a is included in a range of erroneously high value (ALERT H),
controller 140 prints information 315 indicating a second error
being an erroneously high value (ALERT H).
[0320] For example, in the example of printed sheet 300 illustrated
in FIG. 50, the value of HGB (24.3 [g/dL]) corresponds to an
erroneously high value of an adult, and "ALERT H" information 315
indicating a second error is printed together with numerical
information 102a.
[0321] On the other hand, in the example of printed sheet 300
illustrated in FIG. 50, numerical information 102a is not printed
for WBC and PLT. This is because numerical information 102a of WBC
and PLT falls within second determination ranges 360 (see FIG. 55).
In the example of FIG. 50, "ALERT L" information 315 indicating a
second error is printed for the analysis items of WBC and PLT.
Thus, it is possible to know which analysis items fall within
second determination ranges 360 even though numerical information
102a is not outputted.
[0322] When excluding a predetermined abnormal value from the
content to be printed, controller 140 causes substitute indication
313 to be printed in place of the predetermined abnormal value. For
example, controller 140 substitutes numerical information 102a
within second determination ranges 360 for substitute indication
313, and causes output unit 130 to print substitute indication 313.
In the example of FIG. 50, numerical information WBC and PLT within
second determination ranges 360 is printed in the form of
substitute indication 313 "****." Note that any display embodiment
of substitute indication 313 is possible as long as it can be
distinguished from numerical information 102a. Thus, substitute
indication 313 is preferably a character other than a number, a
symbol, or a plane figure, for example. If numerical information
102a is within second determination ranges 360, controller 140
prints information 102b indicating the type of the abnormality
together with substitute indication 313.
[0323] As described above, if numerical information 102a is
included in first erroneous ranges 372 or second erroneous ranges
373, controller 140 outputs information 102b indicating the type of
the abnormality as analysis results 102. Controller 140 prohibits
the outputting of numerical information 102a within second
determination ranges 360, and permits the outputting of information
102b indicating the type of the abnormality.
[0324] On the other hand, if numerical information 102a is outside
first determination ranges 350, controller 140 substitutes
numerical information 102a outside first determination ranges 350
for substitute indication 313 and causes output unit 130 to output
substitute indication 313, and prohibits the outputting of
information 102b indicating the type of the abnormality. To be more
specific, if numerical information 102a falls within none of normal
ranges 371, first erroneous ranges 372, and second erroneous ranges
373 described above, and is outside the linearity guarantee ranges,
the numerical information is substituted for substitute indication
313 on printed sheet 300. Information 102b indicating the type of
the abnormality such as information 314 or 315 is not printed.
[0325] In the example of FIG. 50, for the analysis items outside
first determination ranges 350 and for the analysis items within
second determination ranges 360, controller 140 prints the item
names and prohibits the outputting of numerical information 102a.
When excluding a predetermined abnormal value from the content to
be printed, print unit 135 prints substitute indication 313 in
place of the predetermined abnormal value.
[0326] Note that in the example of FIG. 51, the case where the
outputting of numerical information 102a is prohibited for the
analysis items other than the measurement items includes the case
of a fractionation error of the analysis results. In the case of a
fractionation error, controller 140 prohibits the outputting of
numerical information 102a, and outputs information 102b indicating
the type of the abnormality corresponding to the type of the
fractionation error. Information 102b indicating the type of the
abnormality corresponding to the type of the fractionation error
includes "WBC," "RBC," "PLT," "WBC/PLT," and "WBC Diff". FIG. 50
illustrates an example where WBC Diff is displayed, and "WBC,"
"RBC," "PLT," and "WBC/PLT" are also displayed in the same
manner.
[0327] "WBC" is printed if the number of particles of upper
discriminator value or lower discriminator value is erroneously
high in the particle size distribution of white blood cells. The
discriminator value is a value for distinguishing the distribution
of white blood cells from noise components called ghost. "RBC" is
printed if the number of particles of upper discriminator value or
lower discriminator value is erroneously high in the particle size
distribution of red blood cells, if it is impossible to analyze red
blood cell distribution width (RDW-SD and RDW-CV), or if the
particle size distribution of red blood cells is bimodal. "PLT" is
printed if the number of particles of upper discriminator value or
lower discriminator value is erroneously high in the particle size
distribution of platelets, or if it is impossible to analyze red
blood cell distribution width (RDW-SD and RDW-CV). "WBC/PLT" is
printed if the number of particles having a predetermined value or
less is erroneously high in the particle size distribution of white
blood cells. In the particle size distribution of white blood
cells, "WBC Diff" is printed in any of the cases where it is
impossible to fractionate into small-sized white blood cells and
medium-sized white blood cells, where the discriminator value for
fractionating into small-sized white blood cells and medium-sized
white blood cells is high, where it is impossible to fractionate
into medium-sized white blood cells and large-sized white blood
cells, or where the discriminator value for fractionating into
medium-sized white blood cells and large-sized white blood cells.
In the cases of these fractionation errors, controller 140
substitutes numerical information 102a for a substitute
indication.
[0328] As illustrated in FIG. 50, for each of the analysis items,
controller 140 prohibits the outputting of numerical information
102a outside first determination ranges 350 and the outputting of
numerical information 102a within second determination ranges 360.
For this reason, in the case where numerical information 102a
outside the linearity guarantee range is obtained or "ALERT L"
numerical information 102a is obtained for any of the analysis
items, other analysis items for which printable numerical
information 102a is obtained are printed.
[0329] (Age Section)
[0330] FIG. 53 to FIG. 55 illustrate data examples of numerical
ranges for analysis result determination, for each of the age
sections. As examples of age sections, FIG. 53 illustrates an
infant at the ages of two to eleven, FIG. 54 illustrates a youth at
the ages of twelve to twenty, and FIG. 55 illustrates an adult at
the ages of twenty one or more. The number of sections may be other
than three.
[0331] In the examples of FIG. 53 to FIG. 55, out of normal ranges
371, first erroneous ranges 372, and second erroneous ranges 373,
at least normal ranges 371 differ depending on the age sections.
Controller 140 calculates the age of the subject from subject
attribute information 306, and obtains the numerical ranges of the
age section corresponding to the calculated age. Then, when
numerical information 102a is obtained for each of the analysis
items, analysis unit 120 analyzes which of normal ranges 371, first
erroneous ranges 372, and second erroneous ranges 373, and second
determination ranges 360 numerical information 102a falls within,
based on the numerical ranges of the age section to which the
subject belongs.
[0332] In addition, controller 140 prints normal ranges 371 of the
age section to which the subject belongs on printed sheet 300 as
reference value information 309. In the example of FIG. 49, it is
possible to know from subject attribute information 306 (born in
1965) that the subject is an adult at the age of twenty one or more
as of date information 303. Thus, FIG. 55 illustrates normal ranges
371 of the age section of an adult printed as reference value
information 309. Reference value information 309 is printed for
each of the analysis items. Here, in FIG. 53 to FIG. 55, the
numerical ranges of "ALERT L" second determination ranges 360 are
the same regardless of the age section. However, second
determination ranges 360 may be different for each age section.
[0333] (Predetermined Message)
[0334] Subsequently, the predetermined message printed on printed
sheet 300 is described. In the example of FIG. 49, if there is
numerical information 102a within second determination ranges 360,
controller 140 causes output unit 130 to output the predetermined
message.
[0335] If numerical information 102a is within second erroneous
ranges 373, controller 140 prints message 311 prompting further
testing. To be more specific, if there is numerical information
102a corresponding to an erroneously high value (ALERT H) or an
erroneously low value (ALERT L) within second determination ranges
360 for any of the analysis items, message 311 prompting further
testing is printed. In FIG. 49, as an example, the message
"RECOMMEND FURTHER TESTING" is printed.
[0336] Also, if numerical information 102a is within second
erroneous ranges 373, controller 140 further prints message 312
recommending immediate action. In FIG. 49, as an example, message
312 "Potential ALERT Value should be acted upon IMMEDIATELY" is
printed.
[0337] Also, numerical information 102a of all analysis items is
within normal ranges 371, controller 140 does not display message
311 and message 312. Controller 140 may display a message in
message section 308 based on display conditions for other messages.
For example, regarding numerical information 102a of three analysis
items of WBC, RBC, and HGB, if those three items are not
erroneously low values (ALERT L), but if all of those three items
are low values (Low), controller 140 prints message 311 prompting
further testing but does not print message 312.
[0338] As described above, controller 140 controls the print
content of analysis results 102. "END REPORT" printed on the end of
printed information shows the end of printed sheet 300. Note that
memory 142 of controller 140 stores data necessary to output
analysis results 102 such as first determination ranges 350 and
second determination ranges 360, information 102b indicating the
type of the abnormality, and message 311 and message 312.
[0339] (Modified Example of Second Determination Range)
[0340] FIG. 53 to FIG. 55 illustrates an example where second
determination ranges 360 are set to ranges of erroneously low value
(ALERT L) within second erroneous ranges 373. However, all of
second erroneous ranges 373 may be set to second determination
ranges 360, for example. To be more specific, second determination
ranges 360 may be set also to ranges of erroneously high value
(ALERT H), in addition to ranges of erroneously low value (ALERT
L).
[0341] FIG. 56 illustrates a printing example where both
erroneously low values (ALERT L) and an erroneously high value
(ALERT H) are set as second determination ranges 360. In the
example of FIG. 50, numerical information 102a is printed for the
HGB item corresponding to an erroneously high value (ALERT H). In
the example of FIG. 56, on the other hand, the outputting of
numerical information 102a is prohibited for the HGB item
corresponding to an erroneously high value (ALERT H), and
substitute indication 313 is printed instead of numerical
information 102a. In FIG. 56, numerical information 102a
corresponding to an item being an erroneously low value is
substituted for substitute indication 313. "ALERT L" is assigned to
an item of erroneously low value as information 315 indicating a
second error, and "ALERT H" is assigned to an item of erroneously
high value (ALERT H) as information 315 indicating a second error.
Thus, it is possible to recognize which of an erroneously low value
and erroneously high value numerical information 102a is even when
the numerical information is not printed.
[0342] (Modified Example of Printing Embodiment)
[0343] The example of FIG. 50 and the example of FIG. 56 illustrate
examples of substituting numerical information 102a falling within
second determination ranges 360 for substitute indication 313 and
printing substitute indication 313. However, the configuration may
be such that numerical information 102a falling within second
determination ranges 360 is not displayed, for example. The example
of FIG. 57 illustrates an example where numerical information 102a
falling within second determination ranges 360 is not displayed
when both erroneously low values and an erroneously high value are
set as second determination ranges 360. In FIG. 57, from the
content to be printed, controller 140 excludes numerical
information 102a falling within second determination ranges 360
together with the item names of the analysis items. Thus,
information 102b indicating the type of the abnormality is not
printed either. For this reason, in the example of FIG. 57, the
analysis items themselves of WBC, HGB, and PLT with numerical
information 102a falling within second determination ranges 360
have been excluded from result displaying section 307.
[0344] On the other hand, also in the example of FIG. 57, if there
is numerical information 102a falling within second determination
ranges 360, controller 140 causes message 311 prompting further
testing in message section 308 to be printed. In the example of
FIG. 57, message 312 recommending immediate action is also printed.
The user can recognize there is an error in analysis results 102 by
message 311 prompting further testing and message 312 recommending
immediate action even in the case where numerical information 102a
falling within second determination ranges 360 is deleted together
with the analysis items in result displaying section 307.
[0345] (Modified Example of Output Rules for Analysis Result on
Printed Sheet)
[0346] The example of FIG. 51 illustrates an example where in the
initial test, controller 140 prohibits the outputting of printed
sheet 300 if numerical information 102a is included in first
erroneous ranges 372, and causes retest to be performed. However,
printed sheet 300 may be outputted in the initial test. In the
initial test, if numerical information 102a is included in first
erroneous ranges 372, controller 140 may substitute numerical
information 102a for substitute indication 313 and output the
symbol, or remove numerical information 102a as a not-displayed
item from the print content together with the item names of the
analysis items.
[0347] FIG. 58 illustrates a modified example of output rules for
analysis results 102. In a first modification of FIG. 58,
controller 140 permits the outputting of numerical information 102a
included in normal ranges 371. Controller 140 prohibits the
outputting of numerical information 102a outside first
determination ranges 350, numerical information 102a within first
erroneous ranges 372, numerical information 102a within second
erroneous ranges 373, and numerical information 102a in the case of
a fractionation error. Controller 140 substitutes numerical
information 102a for substitute indication 313 as in FIG. 56, where
the outputting of the numerical information is prohibited. In the
first modification, controller 140 permits the outputting of
information 102b indicating the type of the abnormality, out of
analysis results 102.
[0348] In the case of a second modification of FIG. 58, controller
140 permits the outputting of numerical information 102a included
in normal ranges 371. Controller 140 prohibits the outputting of
numerical information 102a outside first determination ranges 350,
numerical information 102a within first erroneous ranges 372,
numerical information 102a within second erroneous ranges 373, and
numerical information 102a in the case of a fractionation error.
Controller 140 does not display numerical information 102a on
printed sheet 300, where the outputting of the numerical
information is prohibited. To be more specific, numerical
information 102a not within normal ranges 371 is not printed on
printed sheet 300 as in FIG. 57. In the second modification,
controller 140 also prohibits the outputting of information 102b
indicating the type of the abnormality, out of analysis results
102. Thus, in the second modification, when an analysis item having
numerical information 102a outside normal ranges 371 is obtained,
all of its item name, numerical information 102a, and information
102b indicating the type of the abnormality are removed from
printed sheet 300, and the item itself is not printed.
[0349] Additionally, the initial test and the retest are not
distinguished in the first modification and the second modification
of FIG. 58. To be more specific, in the initial test, if numerical
information 102a is included in first erroneous ranges 372, the
outputting of numerical information 102a is prohibited and printed
sheet 300 is outputted.
[0350] (Error Display of Display Unit)
[0351] Subsequently, an error display of display unit 131 is
described. If analysis results 102 include an abnormal value,
controller 140 causes print unit 135 to print information 102b
indicating the type of the abnormality as analysis results 102, and
if there is an error with the apparatus other than with analysis
results 102, the controller causes display unit 131 to display
information indicating there is an error. Analysis results 102 are
outputted collectively on printed sheet 300, and display unit 131
displays information other than on analysis results 102.
Information displayed by display unit 131 includes information on
instructions concerning the series of operations illustrated in
FIG. 7 to FIG. 48, and on an apparatus error.
[0352] To be more specific, display unit 131 displays information
indicating there is an error if there is an error with the
apparatus other than with analysis results 102. Thus, print unit
135 prints an error with analysis results 102, and display unit 131
displays an apparatus error. An apparatus error is not printed by
print unit 135, but is displayed by display unit 131.
[0353] Display unit 131 displays information indicating there is an
error for at least one of an error with analysis unit 120 and an
error with a quality control process of analysis unit 120, for
example. In analysis unit 120, when there is an error in e.g. drive
mechanism 122, fluid circuit 124, or detector 123, controller 140
causes display unit 131 to display information 381 indicating there
is an error as illustrated in FIG. 59. In addition, in the quality
control process, for example, controller 140 causes display unit
131 to display information (screen P117) indicating there is an
error illustrated in FIG. 30 when the quality control process fails
such as when an analysis result of a QC reagent exceeds a reference
range set for the QC reagent.
[0354] Note that the embodiments disclosed herein should be
considered illustrative and non-limited in all respects. The scope
of the invention is given by the scope of claims, not by the
description of the embodiments described above, and moreover
includes all modifications (modified examples) within the meaning
and the scope equivalent to the scope of claims.
