Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application is a US national-phase application of
PCT/CN2015/071559, filed on Jan. 26, 2015. The contents of
PCT/CN2015/071559 are all hereby incorporated by reference.
TECHNICAL FIELD
[0002] The present application relates to the technical field of
blood detection, and particularly to an optical fiber continuous
detecting blood pressure sensor and its wearing apparatus.
BACKGROUND
[0003] Nowadays, normally a non-invasive detecting method is
provided for detecting blood. Non-invasive detecting mainly
includes the stethoscopy method (Korotkoff-Sound Method) and the
succussion method (Oscillography Method). The principle of the
stethoscopy method is to collect Korotkoff sound. The whole
apparatus includes an inflatable and deflatable cuff, a mercury
manometer and a stethoscope. The principle of succussion is to
utilize the oscillographic principle of pulse contour to determine
the SBP (Systolic Blood Pressure) and the DBP (Diastolic Blood
Pressure), which is widely used in most domestic and overseas
non-invasive automated sphygmomanometers nowadays.
[0004] However, these both the two methods all need to inflate and
deflate the cuff. The disadvantages are that: it is difficult to
carry the apparatuses because each of them includes the cuff, the
pump and the valve or the like and thus has a large volume. If the
cuff is used frequently, the tissue and blood vessel beneath the
cuff may be damaged because of being frequently pressed; because a
certain time for inflating and deflating the cuff is needed, the
continuous detection for blood pressure cannot be realized.
[0005] Moreover, the recent study result shows that non-cuff
non-invasive blood pressure detecting detection is possible. It is
a method that utilizes the transmission speed of a pulse wave to
detect a blood pressure. The transmission speed of the pulse wave
refers to the speed of the pulse wave transmits along the artery.
Many study results show that: the pulse wave transmission speed is
related to a blood pressure. A common way to detect the pulse wave
transmission speed is to detect the pulse wave transmission time
which is the time that needed for the pulse wave to transmit from
the heart to radial artery. The pulse transmission time could be
determined by utilizing a reference point on an electrocardiosignal
and another reference point on a pulse wave detected on a
peripheral arterial at during the same cardiac cycle. Pulse The
pulse wave could be detected through an optical method. It is
called as photoplethysmography. Photoplethysmography comprises
lighting the light on the body tissue and detecting the reflected
light, transmission light or scattered light on the body tissue.
The light signal received by the photoelectric detector presents
the variation of blood flow volume of the tissue.
[0006] However, the detecting device utilize pulse transmission
time or speed to detect blood may have the following disadvantages:
detecting the pulse wave transmission time needs an ECG
(electrocardiograph) detecting device and a pulse wave detecting
device, which means many detecting devices are needed; in addition,
in order to detect the needed time of the pulse wave transmitted
from the heart to the a reference point on radial artery precisely
during detection, a subject cannot move freely. If the subject
moves, the locating of the reference would be imprecise, then it
may need to relocate the reference point. Hence, the present pulse
wave detecting apparatus is not suitable for longtime continuous
detecting and it only could be used in a clinic.
[0007] As disclosed on a patent with authorized announcement No.
CN101288587, a strap human blood pressure non-invasive continuous
detecting apparatus utilizes a sphere-shape pulse wave sensor probe
to detect the pulse wave of a human wrist radial artery ensures a
good contact between the probe and the human wrist radial artery by
a compressing spring, and through the positioning of the slot and
the olecroanon, guarantees that the repositioning would be precise
and the wrist movement would be avoided during the continuous
detecting process.
[0008] However, there is also such a problem: the area that
contacts with the probe is the area where pulse wave sensor detects
the pulse wave of the human radial artery, which is a point to
point area detection. Therefore, when the strap human blood
pressure non-invasive continuous detecting apparatus is used, the
probe of the pulse wave sensor has to align with the human wrist
radial artery and the slot has to align with the olecroanon. During
the detecting process, if the strap moves inevitably due to the
movement of the subject's wrist, the positioning of the probe and
the human wrist radial artery will be dislocated. Therefore, it
will cause the positioning imprecision of the human wrist radial
artery relative to the strap human blood pressure non-invasive
detecting apparatus, and the 24 hours non-invasive continuous
detection for human blood pressure cannot be realized.

problems in existing blood detecting methods that there are
complicated structures, it is difficult to carry, a subject's skin
may be damaged, a subject cannot move freely, the positioning is

longtime.
[0010] In order to solve the above technical issues, a technical
solution of an optical fiber continuous detecting blood pressure
sensor provided by the application comprises a sensing band which
is flexible and can be curled into a ring, wherein, the sensing
band includes an inner layer which abuts to the detected surface
and an outer layer; an accommodation space is formed between the
inner layer and the outer layer; an optical fiber is provided in
the accommodation space and extends along the sensing band so as to

shape or, a quadrate corrugated shape, a trapezoidal corrugated
shape, and any combination of at least two of these shapes.

[0014] Further, the optical fiber includes an optical fiber row
which has several S-shape concatenated cablings extending along the

[0015] Further, the optical fiber includes an optical fiber row

[0018] Further, at least two optical fiber rows are superposed

[0019] The application provides an optical fiber continuous blood
pressure sensor, which has the following advantages compared with
the prior art:
[0020] The sensing band is used in the above said optical fiber
continuous detecting blood pressure sensor. The sensing band has an
accommodation space and the accommodation space is provided therein
with an optical fiber. The sensing band is flexible and can be
curled into a ring, therefore, an optical fiber is arranged to
extend along the sensing band and forms a ring-shape sensing area.
The sensing band could be worn on the human arm or wrist,
especially worn on the area of human wrist radial artery. When the
sensing band on human wrist rotates or dislocates because of the
movement of a subject, the sensing area can sense the pulse wave of
the human wrist radial artery, which means that special positioning
is not needed for wearing the sensing band.
[0021] Moreover, the sensing band is covered by an elastic layer
which can be contracted elastically at a certain distance extent.
In this way, the sensing band can be worn on different human wrist.
The elastic layer has certain elasticity, which helps the sensing
band remain a certain elastic contact stress on the wrist.
Therefore, the sensing band is worn on the wrist securely. During
detecting the blood pressure, even the subject moves, the
dislocation between the sensing band and the human wrist radial
artery is not prone to occur easily and there is no need to
reposition the sensing band, which thus a 24 hours non-invasive
continuous detecting for a human blood pressure can be realized,
which is stable and precise.
[0022] Therefore, compared with existing non-invasive detecting
methods, the problems of large volume and being difficult to carry
caused by including the cuff, the pump and the valve or the like
structure can be avoid; the problems that the subject would feel
discomfort because of the inflation and deflation of the cuff and
the wrist tissues and blood vessels could be damaged because of the
frequent compression from the cuff can also be avoided. The problem
that the blood pressure continuous detection cannot be realized
because the inflation and deflation of cuff need certain time can
further be avoided. Compared with existing pulse wave detecting
apparatuses, the problem that the positioning of the reference
point may be inaccurate because the subject moves freely, and that
the longtime and continuous detection cannot be realized can be
also avoided.
[0023] Another purpose of the application is to provide a wearing

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0037] In order to clearly describe the purpose, technical
solutions and advantages of the present application, the
application will be specifically described below with reference to
the accompany drawings and embodiments. It should be understood
that the embodiments described herein are merely specific
embodiments for explaining the present application but not intends
to limit the present application.
[0038] As shown in FIGS. 1-10, the preferred embodiments are
provided by the application.
[0039] It should be noted that, when a part is referred to as
"fixed" or "arranged" on another part, it could be on another part
directly or there may be intermediate parts between the part and
the another part; and when a part is referred to as "connected"
with another part, it could be connected with another part directly
or there may be intermediate parts between the part and the another
part.
[0040] It should be noted that the position terms left, right, up
and down or the like in the embodiment may merely be relative
concepts or references to the normal working condition of the
product, but not intended to limit the application.
[0041] As shown in FIG. 1 and FIG. 2, the optical fiber continuous
detecting blood pressure sensor 10 provided by the application
comprises a sensing band 11 which is flexible and can be curled
into a ring. The sensing band 11 includes an inner layer 111 and an
outer layer 112 that can be close to a human body. An accommodation
space 12 is formed between the inner layer 111 and the outer layer
112. An optical fiber 13 is provided in the accommodation space 12
and arranged to extend along the sensing band 11 so as to form a
sensing area to sense a pulse wave. A signal processor 14 is
provided on one end of the sensing band and used to transform a
light decaying signal generated by decaying a light signal through
the optical 14 fiber into a charge unit so as to calculate the
pulse wave. The signal processor 14 communicates with the optical
fiber 13, and the outer surfaces of the inner layer and the outer
layer are covered by a scalable elastic layer. It should be noted
that, as shown in FIG. 1 and FIG. 2, the reason why the sensing
area could sense the pulse wave is that the fluctuation of the
pulse of the artery would provide a fluctuant pressure on the
sensing band 11. Correspondingly, the optical fiber 11 arranged in
the accommodation space 12 of the sensing band 11 will deform due
to the fluctuant pressure. Because of the deformation of the
optical fiber 13, the transmission of the light signal in the
optical fiber would generate larger refraction, reflection,
scattering and the decaying variation. One end of the sensing band
11 is provided with a signal processor 14 which communicates with
optical fiber 13. At the moment, the light decaying signal of the
optical fiber 13 is transmitted to signal processor 14 through
communication. Signal processor 14 transforms the light decaying
signal into charge unit. Then the charge unit will be calculated
into a pulse wave. Finally, the pulse wave is processed, analyzed
and calculated to obtain the blood pressure value.
[0042] Compared with the prior art, the optical fiber continuous
blood pressure sensor 10 provided by the present embodiment has the
following advantages.
[0043] As shown in FIG. 1 and FIG. 2, the above said optical fiber
continuous blood pressure sensor 10 is provided with a sensing band
11, the sensing band 11 has an inner layer and an outer layer. An
accommodation space 12 is formed between the inner layer 111 and
the outer layer 112 which is provided with optical fiber 13.
Because the sensing band 11 is flexible and can be curled into a
ring, an optical fiber can be arranged to extend along the sensing
band, which will form a ring-shape sensing area. The sensing band
could be worn on the human arm or wrist, especially worn on the
area of human wrist radial artery. When the sensing band on human
wrist rotates or dislocates because of the movement of a subject,
the sensing area can sense the pulse wave of the human wrist radial
artery, that is, the special positioning is not needed for wearing
the sensing band.
[0044] Moreover, as shown in FIG. 1 and FIG. 2, the sensing band is
covered by an elastic layer which can be contracted elastically at
a certain extent. In this way, the sensing band can be worn on
different human wrists. The elastic layer 15 has certain
elasticity, which helps the sensing band 11 remain a certain
elastic contact stress on the wrist. Therefore, the sensing band is
worn on the wrist securely. During detecting the blood pressure,
even the subject moves, the dislocation between the sensing band 11
and the human wrist radial artery would not be prone to occur and
there is no need to reposition the sensing band 11, so that a 24
hours non-invasive continuous detection for a human blood pressure
can be realized, which has high stability and precision.
[0045] Therefore, compared with existing non-invasive detecting
methods, the problem that the volume is large and it is difficult
to carry caused by including the cuff, the pump and the valve or
the like structures can be avoid. The problems that the subject
would feel discomfort because of the inflation and deflation of the
cuff and the wrist tissues and blood vessels could be damaged
because of the frequent compression from the cuff can also be
avoided. The problem that the blood pressure continuous detection
cannot be realized because the inflation and deflation of the cuff
need certain time can be further avoided. Compared with existing
pulse wave detecting apparatuses, the problem that the positioning
of the reference point may be inaccurate because the subject moves
freely, and that the longtime and continuous detection cannot be
realized can also be avoided.
[0046] It should be noted that, the material of the sensing band 11
is soft material, such as silicone. The material of the elastic
layer is elastic material, such as elastic woven material.
[0047] In this embodiment, a preferred embodiment about the
specific structure of the outer surface of the inner layer 111 is
shown in FIG. 1 and FIG. 2, in order to increase the elastic
contact stress on the detected surface of the human wrist radial
artery from the inner layer 111 of the sensing band 11, the outer
surface of the inner layer Ill is formed with a first corrugate
concave-convex structure 1111. In this way, when the sensing band
11 is worn on the human wrist, the first concave-convex structure
1111 of the outer surface of the inner layer 11 will reach the
elastic layer 15, thereby reaching the detected surface. Under the
elastic reaction of the elastic layer 15, the first concave-convex
structure 1111 will be more closer to the detected surface, then
the sensing band 11 would be more securely positioned on the wrist
and not prone to cause the positioning variation because of the
movement of the subject, thereby affecting the proceeding and
precision of the continuous detection of the blood pressure.
[0048] As shown in FIG. 1 and FIG. 2, further, in order to increase
the elastic contact stress on the detected surface of the human
wrist radial artery from the inner layer 111 of the sensing band
11, the outer surface of the inner layer 112 is formed with a
second corrugate concave-convex structure 1112. In this way, when
the sensing band 11 is worn on the human wrist, the second
concave-convex structure will reach the optical fiber 13 located in
the accommodation space 12, and applies pressure towards the
detected surface on the optical fiber. The pressure is transmitted
by the inner layer 111 and the first concave-convex structure 1111,
finally acts on the detected surface through the elastic layer 15
and makes the elastic layer 15 more closer to the detected surface,
then the sensing band 11 would be more securely positioned on the
wrist, and it is ensured that the positioning of the sensing band
11 would not be prone to be affected by the movement of the
subject, so that the proceeding and precision of the continuous
detecting of the blood pressure will be guaranteed.
[0049] Specifically, as shown in FIG. 1, the shape of the first
convex-concave structure is selected from a triangular corrugated
shape, a circular corrugated shape, a quadrate corrugated shape, a
trapezoidal corrugated shape, and any combination of at least two
of these shapes. In like manner, the shape of the second
concave-convex structure 1112 is similar to the shape of the first
concave-convex structure 1111. The shapes of the second
concave-convex structure 1112 and the first concave-convex
structure 1111 only need to meet the requirement of being able to
abut against the detected surface.
[0050] Specifically, the first embodiment about the specific
arrangement of the optical fiber which is located in the
accommodation space, as shown in FIG. 3 and FIG. 4, the optical
fiber 13 includes an optical fiber which has many U-shape
concatenated cablings extending along the longitudinal direction or
width direction of the sensing band 11.
[0051] A second embodiment about the specific arrangement of the
optical fiber located in the accommodation space, as shown in FIG.
6, the optical fiber 13 includes an optical fiber which has many
S-shape concatenated cablings extending along the longitudinal
direction or width direction of the sensing band 11.
[0052] A third embodiment about the specific arrangement of the
optical fiber located in the accommodation space, as shown in FIG.
7, the optical fiber 13 includes an optical fiber which has many
O-shape concatenated cablings extending along the longitudinal
direction or width direction of the sensing band 11.
[0053] A fourth embodiment about the specific arrangement of the
optical fiber located in the accommodation space, as shown in FIG.
5, at least two optical fiber rows are superposed vertically, and
bending portions of the cablings of the two vertically superposed
and adjacent optical fiber rows are staggered.
[0054] The fifth embodiment about the specific arrangement of the
optical fiber located in the accommodation space, as shown in FIG.
10, at least two optical fiber rows are superposed vertically, and
bending portions of the cablings of the two vertically superposed
and adjacent optical fiber rows are staggered transversely and
longitudinally.
[0055] Whichever one of the above five embodiments is adopted by
the arrangement of the optical fiber 13, the ribbon sensing area of
the optical fiber 13 extending along the sensing band 11 is
intensive and uniform. In this way, it helps increase the sensing
sensitivity of the sensing area to the pulse wave of the human
wrist radial artery. No matter what the contact stress from the
inner layer 111 of the sensing band 11 to the detected surface is
inadequate or decreases, the sensing area could sense the pulse
wave of the radial artery sensitively and helps improve the
precision of blood detecting.
[0056] The preferred embodiment about the specific structure of the
signal processor 14. Further, the signal processor includes an
optical detecting module (not shown) used to receive the light
decay signal of the optical fiber; a signal calculating and
processing module (not shown) used to transform the light decaying
signal into the charge unit so as to calculate the pulse wave; a
blood pressure calibrating module (not shown) used to process,
analyze and calculate the pulse wave so as to obtain the blood
pressure value; a memory module used to store the blood pressure
value; and a displaying module (not shown) used to display the
blood pressure value.
[0057] It should be noted that, the displaying module can display
by a fixed terminal or a mobile terminal. For example, the display
module can be a computer screen, a laptop screen, a cellphone
screen or an Ipad screen, etc.
[0058] Specifically, the signal processor 14 includes a
communicating module (not shown) which transmits the blood pressure
value signal and other signals to the fixed terminal or mobile
terminal through wire communication or wireless communication.
Specifically, wire communication can communicate with the terminal
through ports and wireless communication can communicate with the
terminal through a bluetooth module. A fixed terminal or a mobile
terminal, such as a computer or a cellphone can record, stores the
detected blood pressure value or other values, thereby forming a
longterm continuous recording and creating a searchable report.
Moreover, the report containing blood pressure value or other
values can be stired to the cloud, then the report can be
downloaded from the cloud as medical diagnostic reference.
[0059] As shown in FIG. 1 and FIG. 2, the two ends of the inner
layer 111 and the outer layer 112 are connected to the two ends of
the signal processor respectively. The outer surface of the inner
layer 112 is provided with a fixed structure 16 which connects the
outer layer 112 and the signal processor 14 fixedly. The material
of the fixed structure 16 can be bonding material, such as velcro
etc.
[0060] As shown in FIG. 1 and FIG. 9, the inner surface of the
inner layer 111 or the inner surface 112 of the outer surface is
provided with a internal pocket 17. One end of the ribbon sensing
area formed by the optical fiber which extends along the sensing
area 11 is inserted into the internal pocket 17. In this way, the
optical fiber 13 can be arranged in the accommodation space 12
securely.
[0061] The signal processor 14 is provided with an alarming module
(not shown). The alarming module can be a siren or the like. In
this way, the blood pressure value obtained from the blood pressure
calibrating module can be transmitted to the alarming module. If
the blood pressure value exceeds a normal range preset in the
alarming module, the alarm will be triggered and give voice alarm.
The normal range of the blood pressure value can be personalized
and set individually. Therefore, the alarming module has automatic
identification function.
[0062] The application of the above optical fiber continuous
detecting blood pressure sensor 10: it can be manufactured as a
waterproof film wrist. The shape and size of the waterproof film
can be adjusted according to the wrists of different people or the
different locations of the detected radial arteries. The connector
of the optical fiber can be designed as thin and small types, so
that the optical fiber continuous detecting blood sensor can be
further miniaturized and easy to wear. Besides detecting the blood
pressure, the above optical fiber continuous detecting blood sensor
can be used for detecting heart rate, breathing, sleep, calorie
consuming, etc.
[0063] The embodiment further provides a wearing apparatus (not
shown), which includes an optical fiber continuous detecting blood
sensor 10.
[0064] Compared with the prior art, the wearing apparatus provided
by the embodiment has the following advantages:
[0065] Because the wearing apparatus has an optical fiber
continuous detecting blood pressure sensor 10, when a person wears
the wearing apparatus, the wrist or arm could move freely, and 24
hours non-invasive continuous detection for the human blood
pressure could be realized without repositioning.
[0066] The foregoings are merely the preferred embodiments of the
present application, and are not intended to limit the present
application, any modification, equivalent replacement, improvement,
etc, made within the spirit and principle of the present
application, should be encompassed in the scope of the present
application.
