Provisional Patent Application No. 61/778,469, filed Mar. 13, 2013,
and U.S. Provisional Patent Application No. 61/722,287, filed Nov.
5, 2012, the contents and disclosures of which are incorporated
herein by reference in their entirety.
FIELD
[0002] The disclosure herein relates to the collection and
management of medical data of diabetic patients. In particular, the
disclosure relates to the transmission of collected blood glucose
level information from a glucometer to a remote computing device,
such as a mobile phone.
BACKGROUND
[0003] Diabetes is a metabolic disease (metabolism) characterized
by high blood sugar, also called glucose, resulting from disruption
of producing or properly using insulin. Insulin is a needed hormone
to convert sugar, starches and other food during digestion,
providing the human body's key source of energy.
[0004] The blood glucose level or the blood sugar concentration is
the amount of glucose (sugar) present in the blood of a human or
animal. The body naturally tightly regulates blood glucose levels,
while the mean normal blood glucose level in humans is about 72
mg/dL (milligrams/deciliter); however, this level fluctuates
throughout the day. Blood sugar levels outside the normal range may
be an indicator of a medical condition.
[0005] More than 18.2 million people (or 6.3 percent of the
population) in the United States suffer from diabetes. Diabetes can
cause serious health complications including heart disease,
blindness, kidney failure, and lower-extremity amputations. These
complications may be avoided through effective and efficient
balance of sugar levels. The usage of a glucometer (also called a
glucose meter) may be an essential tool for reaching an optimal
balance of blood sugar.
[0006] Glucometers are commonly used by diabetic patients for
self-monitoring of blood glucose levels (and balancing these levels
through the use of medication, diet and physical exercise). Even
though, self-monitoring of blood glucose is critical for the
long-term well-being of diabetic patients, many patients do not
adhere to their prescribed self-monitoring due to a combination of
physiological and psychological barriers.
[0007] Many glucometers use an electrochemical method, based on
test media such as test strips. Test strips are a consumable
element containing chemicals that react with glucose in a drop of
blood used for each measurement. Some glucometers are provided with
sophisticated data handling capabilities, but require using a
connecting media, such as a cable for transferring the data of the
blood glucose level to a computer with diabetes management software
to analyze, display the test results or sending it remotely.
[0008] Diabetics may monitor their own glucose level using a
glucometer. Making such data accessible to a remote health care
professional or a caregiver is facilitated if the glucometer is
connected to a computer.
[0009] It may further be noted that transmission of medical data to
remote care givers may be facilitated by a wired or wireless
Internet connection in the home, using a USB cable connection, for
example. However, collecting the glucose level data and
transmitting is more complicated when a user is outside of his
home. For example, the user may be a child at school, or a patient
on travel. Unless the user has access to a wired or wireless
internet connection, a glucometer cannot transmit recorded glucose
levels results to his physician or caregiver.
[0010] Moreover, a remote computing device that the user may have
on hand, such as the user's cell phone, is not able to cooperate
with a glucometer, particularly where the remote computing device
is configured as a USB slave and the glucometer requires
cooperation with a computer that is configured as a USB master.
[0011] Although diabetes is a chronic condition that can have
serious consequences, with careful attention to blood sugar
control, while using appropriately configured remote communication
helping blood glucose level monitoring, many of the problems
associated with the disease of diabetes may be avoided.
[0012] There is therefore a need, for remote self-monitoring of
blood glucose level, with the ability to transfer the necessary
measured data to a health care professional and/or caregiver.
SUMMARY
[0013] The disclosure herein relates to the collection and
management of medical data related to diabetic patients. In
particular, the disclosure relates to the transferring of collected
blood glucose data over an audio-based channel, for example a
wireless one, which may be useful for medical assessment and care
of an individual suffering from diabetes.
[0014] It is an advantage of the current disclosure that it may
improve blood glucose level monitoring and enable users' on-the-go
to monitor their diabetes and transmit the results to their
physicians, to their parents or other care givers. Furthermore, the
system described herein may provide a more reliable system for
logging diabetes related medical data.
[0015] Aspects of the disclosure present a system for collecting
blood glucose level information and transmitting the collected data
over a wireless audio-based channel for further analysis and
storage. The glucometer measures glucose level of a user, using a
test medium and a media reader component of a glucometer and
structures the measurement into a record by the data processing
unit of the device. The glucometer transmits the measurements
through the transmitter unit, for example over a wireless audio
based channel, to a remote computing device, such as a mobile
phone. A pre-installed application may present the results, history
data and additional medical assessments and further transmit the
measured data to a list of recipients such as physicians, parents,
other care givers, to a remote repository for storage or the
like.
[0016] Optionally, the glucometer and the remote computing device
may communicate using protocols such as audio signaling, ultrasonic
signaling, infrared communication, BLUETOOTH (i.e., one or more
wireless technologies for exchanging distances over short distances
using short-wavelength radio transmissions in the ISM band from
2400-2480 MHz as per the standards defined by the Bluetooth Special
Interest Group), NEAR FIELD COMMUNICATION (i.e., one or more
technologies for smartphones and similar devices to establish radio
communication with each other by touching them together or bringing
them into close proximity, for example based on standards
including, but not limited to, ISO/IES 18092 and those defined by
the NFC Forum), WI-FI (i.e., one or more wireless local area
network products that are based on the Institute of Electrical and
Electronic Engineers' 802.11 standards), ZIGBEE (i.e., one or more
of a suite of high level communication protocols used to create
personal area networks built from small, low-power digital radios
based on the Institute of Electrical and Electronic Engineers'
802.15 standard) or the like.
[0017] In some wireless audio based systems, the glucose level
medical records may be communicated at a variety of audio frequency
levels, where one combination of audio frequencies may represent a
`1` bit, and another combination of audio frequencies may represent
a `0` bit. Accordingly, a synchronization string combination may be
attached before the record data, while a cyclic redundancy check
(CRC) data block may be appended to the record data, for error
detection of the transmission. The system may include: at least one
glucometer for use in measuring of at least one subject; at least
one media reader unit for obtaining at least a first glucose level
medical record from the at least one test medium; at least one
transmitter unit for transmitting measured glucose level record; at
least one remote computing device for receiving at least one
glucose level record using a wireless audio based channel; and a
display mechanism in the remote computing device via which the
glucose level records may be accessed.
[0018] In general, the glucometer may have no display, and may be
unable to display the measured data. According to some
modifications, the glucometer may have means to be directly
connected to an external output unit, such as a computer, a
monitor, a telephone, a tablet, an e-reader device, a handheld
display device, or the like.
[0019] According to various embodiments, the glucometer may
comprise at least one data processor unit, at least one media
reader unit, at least one transmitter unit and at least one power
source unit.
[0020] Optionally, the glucometer monitor may further comprise at
least one memory unit, at least one mini/micro USB port and a
rechargeable battery as a power source.
[0021] Additionally or alternatively, the mini/micro USB port may
be used to recharge the rechargeable battery and/or optionally as
an output mechanism operable to upload measured glucose medical
records stored locally, to a central repository.
[0022] It may be noted that in order to implement the methods or
systems of the disclosure, various tasks may be performed or
completed manually, automatically, or combinations thereof.
Moreover, according to selected instrumentation and equipment of
particular embodiments of the methods or systems of the disclosure,
some tasks may be implemented by hardware, software, firmware or
combinations thereof using an operating system. For example,
hardware may be implemented as a chip or a circuit such as an ASIC,
integrated circuit or the like. As software, selected tasks
according to embodiments of the disclosure may be implemented as a
plurality of software instructions being executed by a computing
device using any suitable operating system.
[0023] In various embodiments of the disclosure, one or more tasks
as described herein may be performed by a data processor, such as a
computing platform or distributed computing system for executing a
plurality of instructions. Optionally, the data processor includes
or accesses a volatile memory for storing instructions, data or the
like. Additionally or alternatively, the data processor may access
a non-volatile storage, for example, a magnetic hard-disk,
flash-drive, removable media or the like, for storing instructions
and/or data. Optionally, a network connection may additionally or
alternatively be provided. User interface devices may be provided
such as visual displays, audio output devices, tactile outputs and
the like. Furthermore, as required user input devices may be
provided such as keyboards, cameras, microphones, accelerometers,
motion detectors or pointing devices such as mice, roller balls,
touch pads, touch sensitive screens or the like.
[0024] According to one aspect of the presently disclosed subject
matter, there is provided a glucometer comprising: [0025] a reader

[0028] It will be appreciated that an audio signal is a mechanical
wave, such as a sound wave or the like, comprising an oscillation
of pressure which is transmitted through a physical medium such as
air, water, or solid metal for example. As used herein, the term
`audio signal` is not limited to sound within the range of human
hearing but may include ultrasonic waves, infrasonic waves or the
like which create effects in a medium which are detectable at a
distance by a suitable sensor such as a microphone or the like. As
described herein, audio signals may be used to carry a data
communication.
[0029] The audio signal may be outside the range of human audible
frequencies, or it may be within it.
[0030] The audio signal may be transmitted at a frequency
detectable by at least one microphone associated with a remote
computing device. The at least one microphone may be selected from
at least one of a group consisting of: an electromagnetic induction
microphone, a dynamic microphone, a capacitance change microphone,
a piezoelectric generation microphone, a light modulation
microphone, a MEMS microphone, and combinations thereof.
[0031] The transmitter may be configured to transmit sounds of
different frequencies to indicate different values of the encoded
data wherein, e.g., for each of the values of the encoded data, the
audio signal comprises at least one of a set of frequencies. Each
member of the set may correspond to an associated value of the
encoded data.
[0032] The values may be coded as binary data, or non-binary data,
such as decimal, octal, hexadecimal, for example based on the
frequency of the sound.
[0033] The transmitter may be configured to transmit a
synchronization string before transmitting the data.
[0034] The transmitter may be configured to transmit one or more of
an error-detection code (such as a cyclic redundancy check) and an
error-correction code with the data.
[0035] The transmitter may be configured to retransmit the data
until a predefined event occurs. The pre-defined event may be the
removal of a test medium from the glucometer, activation of a
button or similar switch on the glucometer, and/or expiration of a
timer or counter.
[0036] The reader may be configured to analyze the glucose level
when the blood sample is disposed on a test medium.
[0037] The transmitter may be further configured to transmit data
regarding the status of one or more aspects of the glucometer, for
example, the battery status.

when disposed on a test medium, wherein the data regarding the
status of one or more aspects of the glucometer comprises
information regarding the test medium, such as calibration
information, information regarding to make/model of the test
medium, etc.
[0039] The controller may be further configured to direct operation
of the reader and the transmitter.

DETAILED DESCRIPTION
[0082] Aspects of the present disclosure relate to communicating
over audio based channel the measured glucose level medical data
for diabetic patients, for determining the approximate
concentration of glucose in the blood, using a medical measurement
device. Transferring the data automatically, over an audio channel
to a remote computing device, that in turn may optionally transfer
the data to a predefined audience list of professional care givers,
parents and the like, is an additional element of the present
disclosure, supporting home blood glucose monitoring for example by
people with diabetes mellitus or hypoglycemia. Furthermore, related
aspects include a medical measurement device without a display, as
well as a medical measurement device which is configured to one-way
communication, i.e., it is designed to transmit messages using a
data protocol, but is not provided with any means configured to
receive such or similar messages.
[0083] It is noted that the systems and methods of the disclosure
herein may not be limited in its application to the details of
construction and the arrangement of the components or methods set
forth in the description or illustrated in the drawings and
examples. The systems and methods of the disclosure may be capable
of other embodiments or of being practiced or carried out in
various ways.
[0084] Alternative methods and materials similar or equivalent to
those described herein may be used in the practice or testing of
embodiments of the disclosure. Nevertheless, particular methods and
materials are described herein for illustrative purposes only. The
materials, methods, and examples are not intended to be necessarily
limiting.
[0085] Reference is now made to FIG. 1 showing a block diagram
schematically representing selected components incorporated into a
distributed system 100 for the gathering and remote management of
glucose level data using a plurality of devices.
[0086] The distributed system 100 comprises a plurality of devices,
such as medical measurement device 140, which may be, e.g., a
glucometer, and remote computing device 150 (which may be, e.g., a
smartphone or any other suitable device such as a communications
device, and which may constitute an output device). The medical
measurement device 140 and remote computing device 150 may be in
communication through a wireless audio based channel and may
further communicate information to remote devices, such as a
central repository device 80, through a network 50 (such as
internet- or mobile-based) to a recipient list. For example, the
medical measurement device 140 may transmit medical data through
the remote computing device 150. The data may thereafter be
communicated to a remote caregiver 90, e.g., via a computer or
handheld device, such as a smartphone.
[0087] It will be appreciated that while the present disclosure is
largely directed toward examples wherein the medical measurement
device 140 is a glucometer, and the medical data measured thereby
is glucose level, any device configured to measure medical data may
be provided without departing from the spirit and the scope of the
present disclosure, mutatis mutandis. For example, the medical
measurement device 140 may be or comprise a thermometer, a scale
(measuring any one or more or weight, body fat, bone density, and
body mass index), a pulmonary edema monitor, and/or be configured
to measure blood oxygen level/saturation, heart rate, blood
pressure, physical activity (e.g., a pedometer) and/or calories
burnt.
[0088] It is noted that a user interface for using the remote
computing device 150, such as a touch screen or the like, may serve
both as input and output devices thereof. Use of a touch screen may
allow the screen to be larger without compromising the size of a
separate input device such as a key pad. Furthermore, a touch
screen input device may be easier to use for the untrained user as
it may use easy to interpret icons rather than complicated text
based instructions.
[0089] Outbound communications channel 170A (the terms "outbound"
and "inbound" when used herein with reference to communication
between the medical measurement device 140 and the remote computing
device 150 are from the point of view of the medical measurement
device) may be provided for communication from the medical
measurement device 140 to the remote computing device 150, which
may be connected to the network directly. According to some
optional and non-limiting modifications, an inbound communications
channel 170B may be provided for communication from the remote
computing device 150 to the medical device 140 such that the
devices may be operable to synchronize data with one another.
[0090] The outbound communications channel 170A may be, e.g., an
audio based communication channel. As such, the medical measurement
device 140 may comprise a transmitter 142, such as a speaker
configured to transmit an audio signal encoding data regarding the
measured medical data (such as, in the case of a glucometer, blood
glucose level) for storage, display, or other purpose. The remote
computing device 150 thus comprises receiver 152, such as a
microphone (e.g., an electromagnetic induction microphone, a
dynamic microphone, a capacitance change microphone, a
piezoelectric generation microphone, a light modulation microphone,
a MEMS microphone, or combinations of the above) configured to
receive the signal transmitted by the transmitter 142.
[0091] Optionally, the remote computing device 150 may be
configured for sending measured medical data stored thereupon to a
professional care giver 90 or uploading to a central repository 80
via a computer network 50. Optionally, the devices may communicate
using protocols such as BLUETOOTH (i.e., one or more wireless
technologies for exchanging distances over short distances using
short-wavelength radio transmissions in the ISM band from 2400-2480
MHz as per the standards defined by the Bluetooth Special Interest
Group), NEAR FIELD COMMUNICATION (i.e., one or more technologies
for smartphones and similar devices to establish radio
communication with each other by touching them together or bringing
them into close proximity, for example based on standards
including, but not limited to, ISO/IES 18092 and those defined by
the NFC Forum), WI-FI (i.e., one or more wireless local area
network products that are based on the Institute of Electrical and
Electonic Engineers' 802.11 standards), or any other suitable
protocol.
[0092] The remote computing device 150 may be pre-loaded with an
application 160, which facilitates, inter alfa, locally viewing
and/or analyzing the data measured by the medical measurement
device 140.
[0093] The application 160 may be configured to send information
regarding the measured medical data to a pre-defined recipient
list. Such a list may include medical professionals, care givers,
parents, and the like. It may store data with a time stamp, so that
the measurement data may be provided within a historical context.
For example, it may be configured, based on the time-stamped data
to graphically present multiple results showing how measured data
vary over time.
[0094] It is noted that the particular architecture and
functionality as described hereinafter, by way of example, refer to
a one-way communication protocol between the medical measurement
device 140 and the remote computing device 150 via the outbound
communications channel 170A. By employing only the outbound
communications channel 170A, the medical measurement device can be
provided without a receiver, thereby lowering its cost.
[0095] Optionally, it is assumed that while using a one-way
communication protocol the transmission from the medical
measurement device 140 may be repeated until a predefined event
occurs. This event may be, for example, a test medium being removed
from the medical measurement device 140, activation of a button or
similar switch on the medical measurement device (in such a case,
the application 160 may be configured to indicate to a user when it
has successfully received data via the outbound communications
channel 170A and/or instruct the user to activate the
button/switch), and/or expiration of a timer or counter.
[0096] Furthermore, the medical measurement device monitor 140 and
the remote computing device 150 may be complementary interdependent
modules, each of which relies on the other to perform the required
operations it does not itself perform. For example, the medical
measurement device 140 may not itself have a display unit and may
only measure the medical data and transmit it. This may be done via
a wireless signal. Additionally or alternatively, the medical
measurement device 140 may connect to the remote computing device
150 via a cable with a mini/micro USB plug.
[0097] Reference is now made to FIG. 2A where a medical measurement
device 140 is shown. In the present example, the medical
measurement device 140 is operable to measure and store information
regarding a glucose level of a subject. It is also configured to
transmit data regarding the information via outbound communications
channel 170A. According to some non-limiting modifications, it may
be configured to transmit the information as data using a wireless
audio based communication protocol. The glucose level and related
collected information may be sent to remote devices (not
illustrated) used, e.g., by caregivers, parents, etc., or to be
stored remotely in a central repository. The transmission may be
configured to occur automatically, for example to a pre-defined set
of devices, and/or may be initiated manually.
[0098] The medical measurement device 140 includes a central
processing unit (CPU) 220 constituting a controller, a media reader
222 (for example a test strip reader), a power source 224, a
transmitter 142, and a media slot 232. Optionally various other
internal elements may be added, such as memory 228 and a micro USB
port 230.
[0099] As mentioned, the medical measurement device 140 may have a
primary function to measure the blood glucose level of a subject.
Accordingly, the user may introduce a test medium 234 into the
media slot 232 for reading by the media reader 222. Various test
media 234 may be used with the medical measurement device 140 as
known in the art. For example, test media may be plastic or paper
strips impregnated with glucose sensitive chemicals such as glucose
oxidase. The strips themselves may have various shapes as required.
As known in the art, a subject typically applies a drop of blood to
a test medium 234 before introducing the test medium 234 into the
medical measurement device 140. The introduction of the test medium
234 into the medical measurement device 140 initiates a process
which includes reading the media, calculating the glucose level,
and transmitting the glucose level via outbound communications
channel 170A to the remote computing device 150.
[0100] According to some modifications, the medical measurement
device 140 also transmits via outbound communications channel 170A
information regarding one or more aspects of itself and/or of the
test medium. Such information may include, but is not limited to,
the battery level of the medical measurement device 140,
calibration data, and/or information regarding specifics of the
test medium (model, etc.).
[0101] The CPU 220 of the medical measurement device 140 is
configured to encode the information before it is transmitted. The
encoding may employ binary data, e.g., with two different tones (or
ranges of tones) each representing different binary digits, or
non-binary, e.g., with several tones (or ranges of tones) being
used, each representing a non-binary digit. For example,
hexadecimal encoding may be used, with 16 different tones (or
ranges of tones) being used, each to represent a digit between Ohex
and Fhex. In addition, data compression may be employed, wherein a
tone contains more than one bit or data. Alternatively, the
information may be sent as an analog signal, for example by
"speaking" the information, i.e., by producing sounds mimicking
human speech. According to any of the above, the audio signal may
be within the range of human audible frequencies, or outside of
it.
[0102] The CPU 220 is further configured to direct operation of the
various elements of the medical measurement device 140, for example
the media reader 222 and the transmitter 142.
[0103] It will be appreciated that although the CPU 220 is
described herein and with reference to the accompanying figures as
a single element, it may comprise several elements working together
to perform the functions thereof. In addition, some of the
functionality thereof may be performed by other elements listed
herein (e.g., encoding may be performed by the same element which
functions as the transmitter 142). In such a case, the CPU 220 is
considered to comprise the elements which perform the functions of
the CPU, despite the fact that they are physically located with
other elements, mutatis mutandis.
[0104] According to some examples of the presently disclosed
subject matter, the transmitter 142 comprises an audio-based
communicator, such as a speaker, operable to transmit audio
signals. The application 160 running on the remote computing device
150 is operable to detect the transmitted audio signals, for
example via the receiver 152 thereof. The software application may
further be configured to decode the information carried by the
audio signals and display the measured glucose level on a display
of the remote computing device. Optionally, the application 160 may
additionally be configured to enable automatic external
communication of the measured glucose level to a pre-defined list
of recipients, or manually communicate the measured data to a
desired communicator.
[0105] Accordingly, according to some examples of the presently
disclosed subject matter, the medical measurement device 140 is a
closed "black-box" type device with few or no external features,
with the exception of, inter alfa, the media slot 232 and a battery
replacement compartment.
[0106] Optionally, the medical measurement device 140 may include
an internal memory 228 for storing recorded data which may be
accessed later. The medical measurement device may include a micro
USB port 230 that may be connected to another device via mini/micro
USB cable. The micro USB port may provide dual functionality of
charging the power source 224, if the power source is a
rechargeable battery and connectivity to the processor 220 for
downloading measured information.
[0107] It is noted that various graphical user interfaces (GUI) for
analyzing the measured glucose information may be used as required,
through the application 160 of the remote computing device 150.
[0108] According to some modifications of the presently disclosed
subject matter, a display is provided in the medical measurement
device 140. This display may thus serve as a user interface, for
example comprising a touch screen using where appropriate, numerals
or text that may be input either via a virtual keypad (not shown)
or adjusted using adjustment arrows (not shown), operable to
receive user input to configure transmission parameters for sending
measured glucose level over the communication channel.
[0109] Optionally, the medical measurement device may include a
basic structure, with a minimal display functionality of buttons
for a user to input data relating to automatic or manual
configuration of the transmission, such as time interval for
transmission resend and the like.
[0110] Reference is now made to FIG. 2B, showing a representation
of an audio communication system 200' in which a medical
measurement device 140 is communicating, using the outbound
communications channel 170A described above with reference to FIG.
1, with the remote computing device 150, installed with application
160 for analyzing received glucose data. The glucose level and
related collected information may be stored into a record, as
described below with reference to FIG. 4, and transmitted to the
remote computing device 150 for management and viewing thereof, and
optionally for further transmission to caregivers, parents, etc.,
or to be stored remotely in a central repository.
[0111] The medical measurement device 140 may be configured to
transmit a record automatically, for example upon introduction of a
test medium. Alternatively, or additionally, transmission may be
initiated manually by a user, for example via an activation button
(not shown) on the device. Transmission signals may be repeated at
regular time intervals at a pre-configured rate, for example, every
4 seconds. Accordingly, according to some modifications of the
presently disclosed subject matter, the medical measurement device
could be provided free of elements which facilitate its receiving
input from the remote computing device. This simplification may
serve to lower the price of the medical measurement device 140
and/or increase its battery life.
[0112] The communication system representation 200' includes the
medical measurement device 140 comprising a transmitter 142, a
remote computing device 150, constituting a remote output device,
such as a smartphone installed with a suitable software application
160 for analyzing the glucose level data, and glucose level data
records 206.
[0113] It may further be noted that the medical measurement device
140 may be pre-configured to send data signals such as medical
content signals or power level notifications at regular time
intervals, for example, every 4 seconds. Such data may be received
by the associated software application 160 running on the remote
computing device 150.
[0114] Reference is now made to FIG. 3, which schematically
represents possible elements for creating a record structure for
transmission from a medical measurement device, using the wireless
audio based communication protocol. The protocol is presented for
illustrative purposes only, it will be appreciated that other
protocols may occur to those skilled in the art and may be
alternatively or additionally utilized.
[0115] The communication transmission elements includes a
synchronization sequence 310, a bit of `1` representation 320 and a
bit of `0` representation 330. These basic elements enable
transmitting, for example, a sample level value of 5 (`101` binary
sequence), for example, as presented in the 340 representation.
[0116] The communication protocol may be based on sending a
sequence of `0` (s) and `1` (s) bits for each measurement of
information sent, with `AB` used as a synchronization signal, `CDE`
as an indication for `1` and `FGH` as an indication for `0`, and
may use the following frequency levels, for example: [0117] A=4000
Hz; B=4200 Hz; (may be used for synchronization) [0118] C=4400 Hz;
D=4600 Hz; E=4800 Hz; (may be used for constructing bit `1`) [0119]
F=5000 Hz; G=5200 Hz; H=5400 Hz; (may be used for constructing bit
`0`)
[0120] Every tone, an `A`, for example, may take 20 milliseconds of
transmission. Thus sending a signal of `AB` may take 40
milliseconds of transmission and a synchronization signal of
`AB`+`AB` may take 80 milliseconds, followed with the actual coded
information.
[0121] Reference is now made to FIG. 4A, representing a possible
audio communication transmission 400 of glucose level measurement
information from the medical measurement device to a remote
computing device, such as a mobile device, for example. The
transmission starts with a synchronization signal 411 and ends with
a cyclic redundancy check (CRC) 414, an error detection code for
detecting errors in the transmitted data.
[0122] It may be noted that, according to some examples, the
transmission is of one-way communication. As no acknowledgement
signal may be sent back when one-way communication is used, it may
be useful to send the data signal, for example including glucose
level related information repeatedly, e.g., every 4 seconds.
According to some modifications, the records and audio
communication protocol may, use functionality and commands to
acknowledge successful reception of the record by the receiver,
configure record timeout, request record resend, etc.
[0123] The communication transmission 400 includes a
synchronization signal 411, followed by blood glucose level data
measurement 412, optionally with battery level data 413 and ended
with an encoded CRC error detection sequence 414.
[0124] The synchronization signal 411 is of 4 T (tones), and may
include sending the `AB` signal twice in a sequence using 2 bits.
The blood glucose level measurement 412 may be within a range of 1
to 512 mg/dl of 27 T (tones) using 9 bits. The optional battery
level information 413 may take a value of 0 to 15 volts, thus of 12
T (tones) using 4 bits. This may be completed with CRC error
detection using 9 bits. Thus, the whole transmission may need a
total of 24 bits. The transmission may also be repetitive, every 4
seconds, for example, and may continue as long as the test medium
is inserted in its slot of the medical measurement device.
[0125] Transmission of each tone may take 20 milliseconds.
[0126] As illustrated in FIG. 4B, in one example, a synchronization
signal may be followed by a glucose level value, a battery level
value and an error detection signal. A sample transmission of an
average glucose level of 72 mg/dl (`01001000`) with battery level
of 6 (`110`) may take the format: [0127]
`AB`+`AB`,`FGH`+`CDE`+`FGH`+`FGH`+`CDE`+`FGH`+`FGH`+`FGH`,`CDE`+`CDE`+`FG
H`, CRC where the leading string `AB`,`AB` represents the
synchronization signal, and the terminal value CRC represents the
error detection.
[0128] The value of the cyclic redundancy check (CRC) for encoding
the record by adding a fixed-length check value may be used for
error detection and data integrity verification. It may be based on
the remainder of a polynomial division or may take a simple format
of repeating a value, for a single value record, such as the blood
glucose level or sending the sum of the two values, for a record
containing the blood glucose level and the battery level, such that
in the example above the value 78, being the sum of 72 and 6, may
serve as the error detection value.
[0129] Reference is now made to FIG. 5 illustrating selected data
integrity actions which are indicated of a method for encoding and
decoding a record. The record is constructed on the medical
measurement device 140 by its CPU 220, after reading the glucose
level information from the test medium and verified by a method on
the application installed on the remote computing device 150.
[0130] According to the method flow, a cyclic redundancy check
(CRC) block may be attached at the end of the glucose information
record. The record may be composed using the CPU 220 of the medical
measurement device 140, resulting in a record having a length of k
bits (step 502). This record may include synchronization signal,
followed with the measured blood glucose level by the media reader
222 of the medical measurement device 140. Optionally, the battery
level may be added to the record. After assembly of the record for
sending, a short block of check data, having possibly 9 bits, may
be attached at the end of the constructed record (step 504). The
record may repeatedly be sent from the medical measurement device
transmitter 226 and speaker 142 of the medical measurement device
140, over a wireless audio based channel to the remote computing
device 150, at preconfigured time intervals, for example every 4
seconds. The record may be received by the communicator 160
receiver component 506, to enable decoding the attached data block
by the application 160, for error detection and correction
purposes. For example, a cyclic redundancy check may be used for
error detection, and error correction codes (for example by
including parity data) may be used for error correction. Once
received, the information is decoded, using the attached CRC string
to validate the record content (step 508), with a possible output
of a record having a length of k bits 510, if the record was
properly received.
[0131] It may be noted, that the form of cyclic redundancy check
(CRC) may apply a customized verification of data integrity, such
as attaching the actual transmitted value, if only the blood
glucose level is sent, or the sum of the measured glucose level and
the battery level, if both values are send.
[0132] Referring to the flowchart of FIG. 6A selected actions are
indicated of a method for transmitting blood glucose level measured
data and related information from the medical measurement device
140 to a remote computing device 150, such as a mobile device
installed with a pre-installed application 160. The transmission of
the glucose measured level data may be communicated over a wireless
audio channel-based system as described hereinabove. Alternatively,
or additionally, the outbound communications channel 170A between
the medical measurement device 140 and the remote computing device
150 may use a wireless communication system, a NEAR FIELD
COMMUNICATION (i.e., one or more technologies for smartphones and
similar devices to establish radio communication with each other by
touching them together or bringing them into close proximity, for
example based on standards including, but not limited to, ISO/IES
18092 and those defined by the NFC Forum) system, and the like.
[0133] It may be noted that for any network-based architecture such
as audio, WI-FI (i.e., one or more wireless local area network
products that are based on the Institute of Electrical and
Electonic Engineers' 802.11 standards), Wireless, NEAR FIELD
COMMUNICATION (i.e., one or more technologies for smartphones and
similar devices to establish radio communication with each other by
touching them together or bringing them into close proximity, for
example based on standards including, but not limited to, ISO/IES
18092 and those defined by the NFC Forum) or the like, the record
stream may have the same or similar record structures answering the
pre-defined communication protocol definitions, as described
hereinabove.
[0134] It may further be noted that the assembly of the record may
be constructed on the medical measurement device, adding a cyclic
redundancy check (CRC) indication for checking record integrity
upon arrival of the record on the remote computing device.
[0135] Alternatively or additionally the form of cyclic redundancy
check (CRC) may apply a customized verification of data integrity,
such as repeating the measured glucose level, for decoding on the
receiving side.
[0136] According to the method, as known in the art, a subject will
typically apply a drop of blood to a test medium before introducing
the test medium into the appropriate medical measurement device
slot (step 602A). The medical measurement device will then measure
using the media reader 222 to define the blood glucose level (step
604A), and optionally store the measured blood glucose level
locally with appropriate timestamp.
[0137] The measured value of blood glucose level may be constructed
into a record as described hereinabove of communication protocol
details, attaching a CRC value for data integrity and error
detection (step 606A). The constructed record may then be sent,
over the available wireless audio channel (step 608A). It is noted
that the remote computing device may then receive the transmitted
signal.
[0138] If the test medium is still inserted in its slot of the
medical measurement device (step 610A), the transmitter of the
medical measurement device may continue to resend the current
record at pre-defined time intervals, for example, say, every 4
seconds (step 612A). If the test medium is pulled out, the
transmitter of the medical measurement device may move into a
holding state, until the next test medium is inserted and measured
(step 614A).
[0139] Referring to the flowchart of FIG. 6B selected actions are
indicated of a method for transmitting blood glucose level measured
data, similar to the method described hereinabove in FIG. 6A, but
with adding related battery level information measured at the
medical measurement device 140 for sending to a remote computing
device 150. The transmission of the blood glucose measured level
data and battery level information may be communicated over a
wireless audio channel-based system as described hereinabove in
FIGS. 3, 4 and 5, to a remote computing device 150, such as a
mobile device pre-installed with application 160.
[0140] Similarly, a cyclic redundancy check (CRC) may additionally
be applied for verifying the data integrity of the received record.
The form of cyclic redundancy check (CRC) may apply a customized
verification of data integrity, such as attaching the sum of the
measured glucose level and the battery level, for decoding on the
receiving side. Alternatively, or additionally, the outbound
communications channel 170A between the medical measurement device
140 and the remote computing device 150 may use a wireless
communication system, a NEAR FIELD COMMUNICATION (i.e., one or more
technologies for smartphones and similar devices to establish radio
communication with each other by touching them together or bringing
them into close proximity, for example based on standards
including, but not limited to, ISO/IES 18092 and those defined by
the NFC Forum) system, and the like.
[0141] According to the method, as known in the art, a subject will
typically apply a drop of blood to a test medium before introducing
the test medium into the appropriate medical measurement device
slot (step 602B). The medical measurement device will then measure,
using the media reader 222 to define the blood glucose level (step
604B), and further measure the current battery level of the device
itself (step 606B), and optionally store the measured blood glucose
level and the battery level, locally with appropriate
timestamp.
[0142] The measured value of blood glucose level combined with the
battery level value may be constructed into a record as described
hereinabove of communication protocol details, attaching a CRC
value for data integrity and error detection (step 608B). The
constructed record may then be sent, over the available wireless
audio channel to the remote computing device (step 610B). If the
test medium is still inserted in its slot of the medical
measurement device (step 612B), the transmitter of the medical
measurement device will continue to resend the current record every
predefined time interval, for example, every 4 seconds (step
614B).
[0143] If the test medium is pulled out, the transmitter of the
medical measurement device may move into a holding state, until the
next test medium is inserted and measured (step 616B).
[0144] Referring to the flowchart of FIG. 6C, selected actions are
indicated of a method for transmitting blood glucose level measured
data, similar to the method described hereinabove in FIG. 6A, but
with substituting the "decision" of whether or not the user
acknowledged that the remote computing device received the
information transmitted by the medical measurement device 140. The
methods described above with reference to FIGS. 6A through 6C may
be useful, for example, wherein the medical measurement device 140
is provided without means to establish an inbounds communications
channel 170B.
[0145] Referring to the flowchart of FIG. 6D, selected actions are
indicated of a method for transmitting blood glucose level measured
data, similar to the method described hereinabove in FIG. 6A, but
without any specified decision regarding resending of data, and
with the data being presented by the remote computing device 150.
It will be appreciated that this method may be combined with other
methods, e.g., it may include a decision step which may necessitate
resending of data to the remote computing device 150. It will
further be appreciated that such a method facilitates providing a
medical measurement device 140 which is free of a data presentation
means.
[0146] Referring to the flowchart of FIG. 7A selected actions are
indicated of a method for receiving the signals, such as blood
glucose level data, on an output device, such as a computing device
running an associated software application method of a remote
computing device. The transmission of the glucose measured level
data from the medical measurement device may be received over a
wireless audio channel using the command elements as described
hereinabove. Alternatively, or additionally, the outbound
communications channel 170A between the medical measurement device
140 and the remote computing device 150 may use a wireless
communication system, a NEAR FIELD COMMUNICATION (i.e., one or more
technologies for smartphones and similar devices to establish radio
communication with each other by touching them together or bringing
them into close proximity, for example based on standards
including, but not limited to, ISO/IES 18092 and those defined by
the NFC Forum) system, and the like.
[0147] It may be noted that for any network-based architecture
audio, Wireless, NEAR FIELD COMMUNICATION (i.e., one or more
technologies for smartphones and similar devices to establish radio
communication with each other by touching them together or bringing
them into close proximity, for example based on standards
including, but not limited to, ISO/IES 18092 and those defined by
the NFC Forum) or the like, the record stream may have the same or
similar record structures answering the pre-defined communication
protocol definitions, as described hereinabove with possible
adjustment needed for the specific network architecture.
[0148] It may further be noted that the disassembly of the received
record may contain data integrity validation mechanism, such as a
cyclic redundancy check (CRC) indication for validating record
integrity by the appropriately designed application of the remote
computing device.
[0149] Alternatively or additionally the form of cyclic redundancy
check (CRC) may contain a customized verification of data
integrity, such as repeating the value of the blood glucose level,
for performing error detection analysis on the receiving side.
[0150] According to the method, the initial step is receiving the
assembled record at the communicator application (step 702A). The
elements of the record are disassembled, to fetch the blood glucose
level (step 704A), thereafter the CRC mechanism for error detection
may be used to verify the data integrity of the fetched value (step
706A). If no error is detected in the received record data (step
708A), the blood glucose level may be compared to previously
received values (within a specified time, using the timestamp as an
indicator) and, thereafter stored for later analysis, immediately
displayed, or any other pre-configured activity (step 710A).
Thereafter, the record may be dropped waiting for an additional
record (step 712A).
[0151] It is noted that it is a particular feature of the designed
application that the glucose level measurement may be stored in the
internal memory of the measurement device or on the remote
computing device. The glucose level measurement may be time-stamped
when stored, such that the measurement may provide an historical
context, providing ability for multiple results to be presented
graphically showing how glucose levels vary over time.
[0152] Referring to the flowchart of FIG. 7B, selected actions are
indicated of an appropriately designed application method of a
remote computing device, such as a mobile device for receiving
blood glucose level measured data and related information from the
medical measurement device. This method is similar to the method
described in FIG. 7A, but with a record including related battery
level information measured at the medical measurement device.
[0153] The transmission of the glucose related measured data may be
received over a wireless audio channel-based system using the
command elements as described. Alternatively, or additionally, the
outbound communications channel 170A between the medical
measurement device 140 and the remote computing device 150 may use
a wireless communication system, a NEAR FIELD COMMUNICATION (i.e.,
one or more technologies for smartphones and similar devices to
establish radio communication with each other by touching them
together or bringing them into close proximity, for example based
on standards including, but not limited to, ISO/IES 18092 and those
defined by the NFC Forum) system, and the like.
[0154] It may be noted that for any network-based architecture
audio, Wireless, NEAR FIELD COMMUNICATION (i.e., one or more
technologies for smartphones and similar devices to establish radio
communication with each other by touching them together or bringing
them into close proximity, for example based on standards
including, but not limited to, ISO/IES 18092 and those defined by
the NFC Forum) or the like, the record stream may have the same or
similar record structures answering the pre-defined communication
protocol definitions, as described hereinabove with possible
adjustment needed for the specific network architecture.
[0155] It may further be noted that the disassembly of the received
record may contain data integrity validation mechanism, such as a
cyclic redundancy check (CRC) indication for validating record
integrity by the designed application of the remote computing
device. Alternatively or additionally the form of cyclic redundancy
check (CRC) may contain a customized verification of data
integrity, such as sending the sum of the blood glucose level and
the battery level of the medical measurement device, for performing
error detection analysis.
[0156] According to the method, the initial step is receiving the
assembled record at the communicator application (step 702B). The
elements of the record are disassembled, to enable fetching of the
blood glucose level (step 704B), and the battery level information
(step 706B), thereafter the CRC mechanism for error detection may
be used to verify the data integrity of the fetched values (step
708B). If no error is detected in the received record data (step
710B), the fetched values of blood glucose level and battery level
may be compared to previously received values (within a specified
time, using the time-stamp as an indicator) and, thereafter stored
for later analysis, immediately displayed, or any other
pre-configured activity (step 712B), then the record may be dropped
waiting for the next record (step 714B).
[0157] It is noted that it is a particular feature of the designed
application that the glucose level measurement may be stored in the
internal memory of the measurement device or on the remote
computing device. The glucose level measurement may be time-stamped
when stored, such that the measurement may provide an historical
context, providing ability for multiple results to be presented
graphically showing how glucose levels vary over time.
[0158] A particular embodiment is described hereinbelow for
illustrative purposes only, but is not limiting and is purely shown
by way of example. A medical measurement device 140, having an
internal power source, such as an electrochemical cell, measures
the blood glucose level using a test medium 234, and transmits the
measured glucose level and/or the power level, over an audio-based
outbound communications channel 170A to a remote computing device
150 such as a mobile phone or the like. The medical data may be
received on the remote computing device 150 by a dedicated
application 160, providing ability of presenting results, history
data and additional medical assessments and further transmitting
the measured data to a list of recipients such as physicians,
parents, other care givers, to a remote repository for storage or
the like. Optionally, in some embodiments, such a medical
measurement device may be a "black box" device with having no
output mechanism except for an audio output configured to
communicate with a remote computing device running a dedicated
software application.
[0159] According to some modifications of the presently disclosed
subject matter, the medical measurement device 140 is provided
without a data presentation means, such as an integral display
which is configured to present information regarding the measured
medical data to a used, for example graphically (using charts,
graphs, etc.) and/or using alphanumeric characters. In addition,
the medical measurement device is provided without an integral
display (for example an indicator light, LED, etc.) configured to
present relative information about the measured medical data, for
example if it is above or below a predetermined threshold and/or
whether or not it is within a pre-determined range of a previous
measurement (or aggregation of a set of previous measurements,
e.g., the arithmetic means thereof). Not providing such a display
may serve to lower the cost of the unit, and/or to increase its
battery life. The remote computing device 150 is configured to
receive information regarding measured data via outbound
communications channel 170A, and to present it on its display.
[0160] Technical and scientific terms used herein should have the
same meaning as commonly understood by one of ordinary skill in the
art to which the disclosure pertains. Nevertheless, it is expected
that during the life of a patent maturing from this application
many relevant systems and methods will be developed. Accordingly,
the scope of the terms such as computing unit, network, display,
memory, server and the like are intended to include all such new
technologies a priori.
[0161] As used herein the term "about" refers to at least
.+-.10%.
[0162] The terms "comprises", "comprising", "includes",
"including", "having" and their conjugates mean "including but not
limited to" and indicate that the components listed are included,
but not generally to the exclusion of other components. Such terms
encompass the terms "consisting of" and "consisting essentially
of".
[0163] The phrase "consisting essentially of" means that the
composition or method may include additional ingredients and/or
steps, but only if the additional ingredients and/or steps do not
materially alter the basic and novel characteristics of the
composition or method.
[0164] As used herein, the singular form "a", "an" and "the" may
include plural references unless the context clearly dictates
otherwise. For example, the term "a compound" or "at least one
compound" may include a plurality of compounds, including mixtures
thereof.
[0165] The word "exemplary" is used herein to mean "serving as an
example, instance or illustration". Any embodiment described as
"exemplary" is not necessarily to be construed as preferred or
advantageous over other embodiments or to exclude the incorporation
of features from other embodiments.
[0166] The word "optionally" is used herein to mean "is provided in
some embodiments and not provided in other embodiments". Any
particular embodiment of the disclosure may include a plurality of
"optional" features unless such features conflict.
[0167] Whenever a numerical range is indicated herein, it is meant
to include any cited numeral (fractional or integral) within the
indicated range. The phrases "ranging/ranges between" a first
indicate number and a second indicate number and "ranging/ranges
from" a first indicate number "to" a second indicate number are
used herein interchangeably and are meant to include the first and
second indicated numbers and all the fractional and integral
numerals therebetween. It should be understood, therefore, that the
description in range format is merely for convenience and brevity
and should not be construed as an inflexible limitation on the
scope of the disclosure. Accordingly, the description of a range
should be considered to have specifically disclosed all the
possible subranges as well as individual numerical values within
that range. For example, description of a range such as from 1 to 6
should be considered to have specifically disclosed subranges such
as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6,
from 3 to 6 etc., as well as individual numbers within that range,
for example, 1, 2, 3, 4, 5, and 6 as well as non-integral
intermediate values. This applies regardless of the breadth of the
range.
[0168] It is appreciated that certain features of the disclosure,
which are, for clarity, described in the context of separate
embodiments, may also be provided in combination in a single
embodiment. Conversely, various features of the disclosure, which
are, for brevity, described in the context of a single embodiment,
may also be provided separately or in any suitable subcombination
or as suitable in any other described embodiment of the disclosure.
Certain features described in the context of various embodiments
are not to be considered essential features of those embodiments,
unless the embodiment is inoperative without those elements.
[0169] Although the disclosure has been described in conjunction
with specific embodiments thereof, it is evident that many
alternatives, modifications and variations will be apparent to
those skilled in the art. Accordingly, it is intended to embrace
all such alternatives, modifications and variations that fall
within the spirit and broad scope of the disclosure.
[0170] All publications, patents and patent applications mentioned
in this specification are herein incorporated in their entirety by
reference into the specification, to the same extent as if each
individual publication, patent or patent application was
specifically and individually indicated to be incorporated herein
by reference. In addition, citation or identification of any
reference in this application shall not be construed as an
admission that such reference is available as prior art to the
present disclosure. To the extent that section headings are used,
they should not be construed as necessarily limiting.
