Description

Sphygmomanometer

The present invention relates to a sphygmomanometer that measures the blood pressure of a patient by wrapping an armband portion.

Blood pressure monitors used by medical personnel such as nurses at medical institutions include a manual pressurization type in which an air balloon for supplying air to the armband and a blood pressure monitor main body are integrated. The arm band portion of the blood pressure monitor has an ischemic air bag for blocking the artery and an arterial pulsation detecting air bag attached to the ischemic air bag. When a medical worker manually holds or releases the air balloon, air is sent from the sphygmomanometer body through the tube to the air bag for ischemia in the armband, and the patient's upper arm is pressurized to measure blood pressure. Medical personnel can easily operate the air balloon with one hand, and when sending air to the air bag for ischemia in the armband, a motor to send air is unnecessary, so quiet blood pressure measurement should be performed even at night (See Patent Document 1).

Japanese Patent No. 4673020

By the way, when the armband is wrapped around the patient's (measured person's) upper arm and air is put into the armband to pressurize the upper arm, the inner surface of the armband moves and bends to the place where the armband is located Occurs. Wrinkles occur at the bent portion of the inner surface of the armband portion. When wrinkles are generated on the inner surface side of the arm band portion, a part of the upper arm skin may be pulled together with the inner surface of the arm band portion, and a part of the upper arm skin may be drawn into the wrinkle. For this reason, the patient feels uncomfortable at the time of blood pressure measurement, and may cause internal bleeding in the upper arm in some cases.

As described above, a part of the upper arm skin is pulled by the wrinkles generated on the inner surface side of the armband portion for the following reason. That is, since the length of the outer surface side of the armband portion and the length of the inner surface side of the armband portion are the same, when the armband portion is wound around the upper arm and pressed, the outer surface side is strained, so the outer surface side is Although it does not remain in the length direction, the inner surface side (the surface side in contact with the upper arm) is loosened and the length direction on the inner surface side is left, and wrinkles are generated on the inner surface side.
Accordingly, an object of the present invention is to provide a sphygmomanometer that can prevent wrinkles from being generated on the inner surface side of the armband portion when the upper arm is pressurized by the armband portion.

The sphygmomanometer according to the present invention is a sphygmomanometer that has an arm band part and measures the blood pressure by winding the arm band part around the upper arm of a person to be measured and pressurizing the arm band part, and the arm band part supplies air A body member having an air bag for ischemia for blocking the upper arm, and the body member has an outer first surface portion and a second surface portion that overlaps the first surface portion and contacts the upper arm.

When the upper arm is wound around the upper arm and the upper arm is pressurized, the first surface portion, which is the outer surface side of the arm belt portion, extends along the circumferential direction of the upper arm. By extending the first surface portion, the second surface portion on the inner surface side of the armband portion does not move along the peripheral direction of the upper arm due to the tension of the first surface portion on the outer surface side, so there is an armband portion. There are no bent parts in the area.
Preferably, the first surface portion is formed so as to have a more three-dimensional shape as compared with the second surface portion by introduction of air for ischemia.
According to the above configuration, since the first surface portion is formed so as to swell and become three-dimensional by introducing air for ischemia, when the armband portion is wound around the upper arm and the upper arm is pressurized, the outer surface of the armband portion The first surface portion that is the side extends along the circumferential direction of the upper arm. By extending the first surface portion, the second surface portion on the inner surface side of the armband portion does not move along the peripheral direction of the upper arm due to the tension of the first surface portion on the outer surface side, so there is an armband portion. There are no bent parts in the area. For this reason, when pressurizing the upper arm with the armband part, it is possible to prevent wrinkles from occurring on the inner surface side of the armband part, so that the patient does not feel uncomfortable during blood pressure measurement and causes internal bleeding in the upper arm There is no fear.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
The embodiments described below are preferred specific examples of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these embodiments.

(First embodiment)
FIG. 1 is a perspective view showing a preferred embodiment of the sphygmomanometer of the present invention. FIG. 2 is a front view of the sphygmomanometer shown in FIG.
The sphygmomanometer 1 shown in FIG. 1 is a manual pressurization method by a medical staff such as a nurse, and pressurizes an air bag in an armband attached to a patient's upper arm T, thereby allowing the patient who is the subject to be measured. Blood pressure can be measured, and the patient does not feel uncomfortable during blood pressure measurement, and there is no risk of internal bleeding in the upper arm T.
In the manual pressurization type sphygmomanometer 1, an air balloon (pressurization unit) 5 and a sphygmomanometer body unit 4 are integrated. A medical worker can pressurize the air balloon 5 with one hand, and the sphygmomanometer 1 can quietly measure blood pressure even at night because there is no motor sound.

When using the sphygmomanometer 1, the medical staff can select three measurement modes according to the patient's pathological condition. The three measurement modes are a normal mode, a slow mode, and an auscultation mode.
The normal mode is a mode in which blood pressure measurement can be performed more quickly by automatic measurement. Slow mode is a mode in which the pressure reduction rate after pressurization can be set slower than the pressure reduction rate after pressurization in normal mode, and blood pressure can be measured for patients with low blood pressure or patients with weak pulses. It is. The auscultation mode is a mode in which a medical worker measures blood pressure by an auscultation method using a stethoscope without performing automatic measurement.

The measurement method in the sphygmomanometer 1 shown in FIG. 1 and FIG. 2 is an oscillometric method (a so-called double cuff method using an air bag for ischemia and an air bag for detecting arterial pulsation). As shown in FIG. The upper arm T of the patient who is the subject. As a power source to be used, for example, a dry battery is used.
As shown in FIGS. 1 and 2, the sphygmomanometer 1 has a sphygmomanometer main body 2 and an armband 3. The sphygmomanometer main body 2 includes a housing 4 and an air balloon 5. The air supply balloon 5 is a pressurizing unit that can send internal air to the armband unit 3 side when a medical worker holds the hand and pressurizes it. The air supply balloon 5 is made of an elastically deformable material having elasticity.

A housing 4 of the sphygmomanometer main body 2 shown in FIGS. 1 and 2 is made of plastic, and has a rectangular display unit 8, a power switch 9, a mode switch 10, and an exhaust switch 11. The display unit 8 is, for example, a liquid crystal display device or an organic EL (electroluminescence) display device, and may be a single color display or a color display. The display unit 8 can display a maximum blood pressure value, a minimum blood pressure value, a pulse rate, and which of the three measurement modes described above is selected.
The power switch 9 shown in FIG. 1 and FIG. 2 can be turned on or off by the medical staff when pressed. When the medical switch is pressed, the mode switch 10 can switch the measurement mode to any of the above-described normal mode, slow mode, and auscultation mode. The exhaust switch 11 can be forcibly exhausted by a medical worker when the air in the air bag for ischemia in the armband portion 3 and air in the air bag for detecting arterial pulsation, which will be described later, is pressed. it can.

The two

tubes

6 and 7 shown in FIG. 1 are flexible tubes that connect the housing 4 of the blood pressure monitor main body 2 and the armband 3. The tube 6 is thicker than the tube 7. One end portion 6 B of the tube 6 is connected to the upper portion of the housing 4 via the connector portion 12. One end portion 7B of the tube 7 is connected to the upper portion of the housing 4 via a plug 7C and a connector portion 12. The vicinity of the

ends

6B and 7B of the

tubes

6 and 7 are fixed by a holder 13. As described above, the

tubes

6 and 7 are fixed by the holder 13 so that the

tubes

6 and 7 are not separated, but the one end portion 7B of the thin tube 7 is connected to the one end portion 6B of the thick tube 6. In comparison, the length of the tube 7 has a margin so that the movement of the tube 7 can follow the movement of the tube 6. As a result, even if the thick tube 6 is pulled in an unreasonable direction by pulling the thick tube 6, the thin tube 7 is not pulled by being pulled by the thick tube 6.

As shown in FIG. 1, an extension portion 14 is formed projecting downward from the lower portion of the housing 4. The extension portion 14 is a thin plate-like member that covers a part of the front portion 5S of the air balloon 5. As shown in FIG. 2, air taken in the air balloon 5 by a medical worker holding the extension 14 while supporting it with the finger of the hand H and repeatedly holding and releasing the air balloon 5. Can be supplied to the air bag for ischemia in the armband portion 3 and the air bag for detecting arterial pulsation through the piping in the blood pressure monitor main body 2 and the

tubes

6 and 7. Projections 4T are formed on both sides of the housing 4 so that the housing 4 can be easily gripped.

In FIG. 3, the example of the display item which the display part 8 of the blood pressure meter main-body part 2 can display is shown.
As shown in FIG. 3, the display unit 8 includes a maximum blood pressure value display area 8A, a minimum blood pressure value display area 8B, a pulse display area 8C, a pulse wave signal display area 8D, a previous value display area 8E, and a display area during exhaust. 8F, under-pressurized display area 8G, over-pressurized display area 8H, and selected mode display area 8K.
The systolic blood pressure value display area 8A shown in FIG. 3 displays the instantaneous blood pressure during pressurization and decompression, and finally displays the systolic blood pressure value. The lowest blood pressure value display area 8B displays the lowest blood pressure value finally determined.

The pulse display area 8C shown in FIG. 3 displays the measured pulse value. The pulse wave signal display area 8D displays the magnitude of the detected pulse wave signal, and the magnitude of the pulse wave signal is displayed in a bar shape that moves to the left and right. In the case of a patient with a normal pulse, the display of the magnitude of the pulse wave signal rhythmically increases or decreases from side to side, but in the case of a patient with arrhythmia, the display of the magnitude of the pulse wave signal Rhythmically does not increase or decrease from side to side. By providing this pulse wave signal display region 8D, it is possible to visually determine whether or not the patient who is the subject has arrhythmia.

The previous value display area 8E shown in FIG. 3 blinks or lights up when the power switch 9 is pressed to activate the operation of the sphygmomanometer body 2, and the highest blood pressure value, lowest blood pressure value, and pulse value measured last time are the highest. It is displayed in the hypertension value display area 8A, the minimum blood pressure value display area 8B, and the pulse display area 8C. Then, after a while or when a medical worker pressurizes the air balloon 5 to supply air, the display of the highest blood pressure value, the lowest blood pressure value, and the pulse value measured last time disappears. In the value display area 8E, when the power switch 9 is pressed and the operation of the sphygmomanometer main body 2 is started, the blinking or lighting is also extinguished.
The display area 8 F during exhausting blinks when the air in the air bag for ischemia and the air bag for detecting arterial pulsation in the armband 3 is rapidly exhausted. The display area 8F during exhaust also blinks when the exhaust switch 11 is pressed.

When the underpressurized display area 8G shown in FIG. 3 is lit or blinking, it indicates that the pressure in the armband 3 has not reached a level sufficient for blood pressure measurement. Can be further encouraged to send air using the air balloon 5.
When the overpressurization display area 8H is lit or flashing, it indicates that the pressure in the armband 3 is equal to or higher than a predetermined pressure (for example, 320 mmHg or higher), and the medical worker overpressurizes. By confirming the display area 8H, it is possible to prompt the user to stop the pressurizing operation.

The mode display area 8K being selected shown in FIG. 3 displays which mode is selected from the normal mode, the slow mode, and the auscultation mode when the mode switch 10 is pressed. By selecting this mode, the exhaust (decompression) speed can be changed.
When the normal mode is selected, the exhaust speed is set to about 5 mmHg / sec, for example. In the normal mode, there is an advantage that the measurement time can be made relatively short because the exhaust speed is relatively fast. On the other hand, since the increment of the pressure change measurement is large, there is no particular problem when measuring a person with stable pulse, but when measuring the blood pressure of a person with arrhythmia, the pulse is easily lost. Measurement error may increase.

Therefore, a slow mode is provided, and when this slow mode is selected, the exhaust speed is set to approximately half of the normal mode, for example, 2.0 to 2.5 mmHg / sec. In this manner, in the “slow” mode, the pressure change can be seen in detail by reducing the pressure more slowly than usual, so that the person with an arrhythmia that is likely to lose a pulse can be measured more accurately.
Furthermore, the auscultation mode is a mode in which measurement is performed manually using a stethoscope. In this case, the exhaust speed is set to about half of the normal mode, for example, 2.0 to 3.0 mmHg / sec.

Next, an example of a control circuit block arranged in the sphygmomanometer body 2 of the sphygmomanometer 1 will be described with reference to FIG. FIG. 4 shows an example of a control circuit block arranged in the sphygmomanometer main body 2 and a configuration example of the armband 3.
A control unit 100 is disposed inside the housing 4 of the sphygmomanometer main body 2 shown in FIG. 4, and the control unit 100 has a central processing unit (CPU). The control unit 100 includes a display unit 8, a power control unit 102, a power switch 9, a mode switch 10, an exhaust switch 11, a pressure sensor 110, a ROM (read only memory) 111, and a RAM (random access memory). ) 112, the driving unit 113, and the buzzer 114.

4 is controlled by the power control unit 102, so that power is supplied to the control unit 100. The battery 115 may be a dry battery or a secondary battery (rechargeable battery). However, it is preferable that a medical worker grips with one hand and pressurizes the air balloon, and the power consumption at the time of measurement is about 0.5 W. Therefore, as a power source to be used, for example, an AA battery ( DC1.5V) or AA rechargeable battery (DC1.5V) is used. Therefore, when a new AA battery (DC1.5V) is used, blood pressure can be measured about 1000 times, and the entire sphygmomanometer 1 can be reduced in size and weight (about 135 g). The display unit 8 displays the display items described with reference to FIG.

As will be described later in detail in FIG. 4, the armband portion 3 has a main body member 80, and the main body member 80 includes an air bag 20 for ischemia and an air bag 40 for detecting arterial pulsation. Is provided. The pressure sensor 110 detects the pressure in the air bag 20 for ischemia and the pressure in the air bag 40 for detecting arterial pulsation. The pressure sensor 110 detects a change in pressure in the air bag 20 for ischemia. Moreover, the pressure in the air bag 40 for detecting arterial pulsation varies due to the vibration of the arterial wall due to arterial pulsation of the upper arm T that occurs during blood pressure measurement, that is, due to the pulse wave of the artery of the upper arm T, but the pressure sensor 110. Detects this pressure fluctuation.
The air bag 20 for ischemia is also called a large cuff, and the air bag 40 for detecting arterial pulsation is also called a small cuff. An air bag 40 for detecting arterial pulsation is built in the ischemic air bag 20. The sphygmomanometer 1 has a so-called double cuff type armband portion 3.

The ROM 111 shown in FIG. 4 stores a control program and various data in advance. The RAM 112 temporarily stores calculation results and measurement results. The drive unit 113 drives the electromagnetic valve 116 according to a command from the control unit 100. When the armband portion 3 pressurizes the upper arm T, the fluctuation value of the pressure detected by the pressure sensor 110 is considerably larger than the fluctuation value of the pressure at the time of depressurization, which is the measurement time. For this reason, when the control unit 100 determines that the fluctuation value of the pressure detected by the pressure sensor 110 is equal to or greater than a predetermined value, the control unit 100 determines that the pressurization is being performed and issues a command to the drive unit 113. The electromagnetic valve 116 is closed.

On the other hand, when the control unit 100 determines that the pressure fluctuation value (increase value) is substantially zero or in a reduced pressure state within a predetermined period with respect to the pressure detected by the pressure sensor 110, the control unit 100 instructs the drive unit 113. Then, the electromagnetic valve 116 is opened so that the pressure reduction speed becomes a predetermined value. The operation of the sphygmomanometer 1 shifts from the pressurization mode to the measurement mode.
The forced exhaust valve 117 is opened by a command from the control unit 100 when the exhaust switch 11 is pressed.
The buzzer 114 generates a predetermined warning sound according to a command from the control unit 100. For example, the buzzer 114 may cause an error when the blood pressure value is determined when the power switch 9 of the sphygmomanometer body 2 is pressed and the display unit 8 is ready for display, when the mode is switched by pressing the mode switch 10, A warning sound is generated when an error occurs.

4 is disposed between one end 6B of the tube 6 and the conducting tube 120. The forced exhaust valve 117 shown in FIG. The air supply bulb 5 is connected to one end portion 6B of the tube 6 through the manifold 118, the branching portion 119, the conducting tube 120, and the forced exhaust valve 117. The other end 6A of the tube 6 is connected to the air bag 20 for ischemia. In addition, the air supply balloon 5 is connected to the pressure sensor 110 via the manifold 118, the branch portion 119, the manifold 121, and the branch portion 122. The branch portion 122 is connected to one end portion 7 B of the tube 7. The other end 7A of the tube 7 is connected to an air bag 40 for detecting arterial pulsation.

Thereby, the pressure sensor 110 can detect a change in pressure in the air bag 20 for ischemia and a change in pressure in the air bag 40 for detecting arterial pulsation. By repeating the pressurizing operation in which the medical worker grips and releases the air balloon 5 by hand, the external air taken into the air balloon 5 is branched from the air balloon 5 into the manifold 118. The air can be sent into the ischemic air bladder 20 through the portion 119, the conducting tube 120, the forced exhaust valve 117, and the tube 6. In addition, by repeating the pressurizing operation in which a medical worker grips and releases the air supply balloon 5 by hand, the external air taken into the air supply balloon 5 is supplied to the manifold 118, the branch portion 119, The air can be sent to the air bag 40 for detecting arterial pulsation through the manifold 121, the branch part 122, and the tube 7.

Next, referring to FIGS. 5A and 5B, a structural example of the armband portion 3 will be described.
FIG. 5 shows a structural example of the armband portion 3. FIG. 5A is a perspective view showing the inner surface side of the armband portion 3, and FIG. 5B is a perspective view showing the outer surface side of the armband portion 3.
As shown in FIG. 1, the armband portion 3 is wound directly on the skin (bare skin) of the patient's upper arm T as a person to be measured, and sends air into the ischemic air bag 20 to pressurize the upper arm T. .
In the embodiment of the present invention, for example, the armband 3 has a double cuff type bladder including an air bag for ischemia (large bag) 20 and an air bag for detecting arterial pulsation (small bag) 40. It has a so-called one-piece cuff structure that does not have an outer cloth for covering the bladder. In other words, the armband portion 3 is composed of one member including an air bag for ischemia (large bag) 20 and an air bag for detecting arterial pulsation (small bag) 40.

As shown in FIG. 5, the armband portion 3 includes a main body member 80, a sheet-like sealing member 52, a male member 61 of the surface fastener 60, a female member 62 of the surface fastener 60, and arterial pulsation detection. Air bag (small bag) 40.
The male member 61 of the surface fastener 60 can be detachably attached to the female member 62 of the surface fastener 60. The male member 61 of the surface fastener 60 is one member of the surface fastener, and the female member 62 of the surface fastener 60 is the other member of the surface fastener.

A main body member 80 shown in FIG. 5A has a rectangular first surface portion 50A and a rectangular second surface portion 50B.
The first surface portion 50A is on the outer surface portion side of the armband portion 3 shown in FIG. 1, the second surface portion 50B is on the inner surface portion side of the armband portion 3, and the second surface portion 50B is the skin (skin) of the upper arm T. It is a surface that touches directly.
The first surface portion 50A and the second surface portion 50B are rectangular members formed along the longitudinal direction X. 50 A of 1st surface parts and the 2nd surface part 50B can form the rectangular main body member 80 by mutually superimposing along a X direction. The X direction is the peripheral direction of the upper arm T.
The first surface portion 50A is formed of a material that is more easily extended in the X direction than the second surface portion 50B. Various such materials and forms are conceivable, but more preferably, the second surface portion 50B is divided into a plurality of regions along the X direction, and each of the divided regions is, for example, when ischemic air is introduced. As will be described later, it expands three-dimensionally or three-dimensionally and extends in the X direction.

As shown in FIG. 5, the first surface portion 50 A and the second surface portion 50 B of the main body member 80 preferably have a double structure having a first sheet layer 71 and a second sheet layer 72, respectively. The first sheet layer 71 is an inner layer, and the second sheet layer 72 is an outer layer. The first sheet layer 71 is made of, for example, a polyurethane resin, and the second sheet layer 72 is made of, for example, a nylon resin. However, the first sheet layer 71 is not limited thereto, and may be made of, for example, polyester. This nylon resin is a trade name of DuPont, USA, and is a general name for polyamide fibers (resins). It has high water absorption, high crystallinity, excellent chemical resistance, excellent toughness, and impact resistance. And flexibility. The first sheet layer 71 is not limited to a polyurethane resin, but may be made of natural rubber, synthetic rubber, elastomer, PVC (polyvinyl chloride), or the like.
Thus, the reason why the first sheet layer 71 is made of, for example, urethane resin is that it can be inflated by forming an air bag for ischemia (large bag) and putting in air, and the air does not escape. It is for doing so. The second sheet layer 72 is made of nylon resin, for example, because it covers the first sheet layer 71 and directly touches the skin of the upper arm T of the patient (measured person) shown in FIG. This is because importance is placed on flexibility and flexibility.

6 is a perspective view showing the first surface portion 50A and the second surface portion 50B of the main body member 80 shown in FIG. The first surface portion 50A and the second surface portion 50B shown in FIG. 6 show a state before they are fused and integrated with each other by high frequency. As described above, the first surface portion 50A is on the outer surface portion side of the armband portion 3 shown in FIG. 1, and the second surface portion 50B is on the inner surface portion side of the armband portion 3, and the skin of the upper arm T (skin ) Directly touch the surface.
The length along the peripheral direction of the upper arm T of the first surface portion 50A is set longer than the length along the peripheral direction of the upper arm T of the second surface portion 50B. That is, the length M1 in the X direction of the first surface portion 50A is set to be larger than the length M2 in the X direction of the second surface portion 50B, and the ratio between the length M1 and the length M2 is, for example, long Length M1: Length M2 = 108 to 113: 100.
The width N1 in the V direction of the first surface portion 50A is set to be the same as the length N2 in the V direction of the second surface portion 50B, or the width N1 is set to be slightly larger than the width N2.

FIG. 7 is a perspective view showing an example of a state in which the first surface portion 50A shown in FIG. 6 is overlaid on the second surface portion 50B and fixed by, for example, high frequency fusion.
As shown in FIG. 7, the first surface portion 50A and the second surface portion 50B are overlapped with each other, and the first surface portion 50A and the second surface portion are formed so as to form a plurality of three-dimensionally formed portions 500 on the first surface portion 50A. For 50B, high-frequency fused

portions

90, 90B, 90C, 93, 92, 91, 94 are formed. This three-dimensional formation part 500 also refers to a three-dimensional fusion part.

As a result, the high-frequency fused

portions

90, 90 B, 94, 91 form a blood-insulating air bag (large bag) 20, and the remaining high-frequency fused

portions

92, 94, 90 C, 93 are arm-wrapped portions 96. Is forming. In the example of FIG. 7, three three-dimensionally formed portions 500 are formed in the region of the ischemic air bag (large bag) 20, and three are formed in the region of the arm winding portion 96, but are not limited thereto.
The three-dimensionally formed portion 500 may be formed in advance on the planar first surface portion 50A shown in FIG. Alternatively, the three-dimensionally formed portion 500 is formed by integrating the planar first surface portion 50A and the planar second surface portion 50B with the high-frequency fused

portions

90, 90B, 90C, 93, 92, 91, 94, and at the same time, You may form with respect to 50 A of 1st surface parts.
In this manner, the main body member 80 is fixed by overlapping the first surface portion 50A and the second surface portion 50B, and a plurality of three-dimensionally formed portions 500 are formed on the first surface portion 50A.

Here, referring back to FIG. 5, as shown in FIG. 5A, a lid member 50 K is formed in the second surface portion 50 B of the main body member 80 by being cut in advance. By opening the lid member 50K, an air bag 40 for detecting arterial pulsation is inserted inside the lid member 50K. The air bag 40 for detecting arterial pulsation is located between the first surface portion 50A and the second surface portion 50B, and is held by the abutting member 51 from the back side.
Thereby, the air bag 40 for detecting arterial pulsation is held between the lid member 50K and the abutting member 51 in a sealed state, for example, by high frequency fusion. For this reason, the air bag 40 for detecting arterial pulsation is built in the air bag 20 for ischemia.

Although the air bag 40 for detecting arterial pulsation shown in FIG. 5A is supported by a support plate (not shown), a large pressure fluctuation in the air bag 20 for ischemia causes air bag 40 for detecting arterial pulsation. Not communicated to. For this reason, a minute pressure fluctuation in the air bag 40 for detecting arterial pulsation can be detected without being influenced by a large pressure fluctuation in the air bag 20 for ischemia. In addition, since the support plate is disposed, the air bag 40 for detecting arterial pulsation has a function capable of being brought into close contact with the bare skin of the upper arm T of the patient.

As shown in FIG. 5 (B), the male member 61 of the hook and loop fastener 60 is disposed on the three-dimensionally formed portion 500 of the first surface portion 50A, and the male member 61 is relative to the three-dimensionally formed portion 500 of the first surface portion 50A. It can be securely attached by sewing with thread. Thus, the male member 61 is securely fixed to the first surface portion 50A by sewing as compared to the case where the male member 61 is fixed by fusion (fusion) because the attachment strength of the male member 61 to the first surface portion 50A is increased. It is because it can improve.

However, since the thread passes through the male member 61 of the surface fastener 60 and the three-dimensionally formed portion 500 of the first surface portion 50A by sewing with a thread, the through hole 80P is opened. Between the first surface portion 50A and the inner surface side, air passes and the air in the air bag 20 is leaked.
Therefore, in order to prevent the passage of air through the through-hole 80P, as shown in FIG. 5B, the sheet-like sealing member 52 is, for example, high-frequency with respect to the inner surface of the three-dimensionally formed portion 500 of the first surface portion 50A. It is fixed by fusion. Thereby, since the sheet-like sealing member 52 can block the through hole 80P through which the thread 80 passes, between the outer side of the male member 61 and the inner surface side of the three-dimensionally formed portion 500 of the first surface portion 50A. Air can be prevented from passing through, and air leakage in the ischemic bladder 20 can be reliably prevented.

As shown in FIGS. 5A and 5B, when the main body member 80 is formed, the first surface portion 50A and the second surface portion 50B are formed by sealing the inside thereof.

Fusion parts

90, 90B, 90C, 93, 92, 91, 94 are provided.
Thereby, in the main body member 80, the high

frequency fusion parts

90, 90B, 90C, 93, 92, 91, 94 are divided into the air bag 20 for ischemia and the arm winding part 96 so as to be airtight. . The air bag 20 for ischemia is hermetically sealed by high-frequency fused

portions

90, 90B, 94, 91. The tube 6 is airtightly connected to the tube connection hole 20 H of the ischemic air bladder 20. Further, the arm winding portion 96 is formed to be hermetically sealed by the high

frequency fusion portions

92, 94, 90C, 93.

As shown in FIG. 5A, in the arm winding portion 96, the female member 62 of the surface fastener 60 is attached to the outer surface 50Q of the second surface portion 50B by sewing using the thread 99. The reason why the female member 62 is thus fixed by sewing with the thread 99 is to improve the attachment strength of the female member 62. The female member 62 is fixed to the outer surface 50Q of the second surface portion 50B by sewing using the thread 99, so that a through hole 98 is formed in a portion through which the thread 99 is passed. The through hole 98 is formed to penetrate from the outside of the first surface portion 50A to the first surface portion 50A, the second surface portion 50B, and the outside of the female member 62 of the surface fastener 60.

The through hole 98 is formed so as to penetrate from the outside of the first surface portion 50A of the arm winding portion 96 to the outside of the first surface portion 50A, the second surface portion 50B, and the female member 62 of the surface fastener 60. Because of the reason. The arm winding portion 96 shown in FIG. 5A is a portion where air does not flow, that is, a portion that does not expand when the upper arm is pressurized, unlike the air bag 20 for ischemia. For this reason, it is desirable to prevent air from entering the arm winding portion 96 in order to tightly wind around the upper arm T. However, when the main body member 80 is actually manufactured, in the main body member 80, a plurality of high-frequency fused

portions

90, 90B, 90C, 93, 92, 91, and 94 are provided with the hemostasis air bag 20 and the arm winding portion. If it is formed so that it can be hermetically divided into 96, it is difficult to prevent air from entering the arm winding portion 96 at all.

Therefore, when attaching the female member 62 of the hook-and-loop fastener 60 to the arm winding portion 96, the through hole 98 is formed so as to penetrate the front and back of the arm winding portion 96, so that the arm winding portion is utilized using the through hole 98. The air which is to remain in 96 can be pushed out completely. For this reason, there is an advantage that air bleedability from the arm winding portion 96 is improved. Since the arm winding portion 96 of the arm band portion 3 does not cause unnecessary swelling due to residual air, the arm band portion 3 can be reliably and easily wound so as to be in close contact with the upper arm T of the patient. .
As the arm band 3 shown in FIG. 5, different sizes can be prepared in consideration of the patient's arm circumference. The size of the armband portion 3 is, for example, SS size, S size, M size, L size, and LL size from small to large.

Next, a usage example of the above-described blood pressure monitor 1 will be described with reference to FIGS.
FIG. 8 shows a state in which the armband portion 3 is directly wound around the skin (bare skin) of the upper arm T of the patient. FIG. 9 shows an example of a procedure for winding the armband 3 directly around the skin of the upper arm T of the patient. As shown in FIG. 8, the medical staff directly wraps and fixes the arm band 3 around the skin of the upper arm T of the patient as follows.

As shown in FIG. 8, the arm band portion 3 to be wound around the upper arm T has the first surface portion 50A on the lower side, the second surface portion 50B on the upper side, and the second surface portion 50B as shown in FIG. 9 (A). The side is applied from the lower side of the upper arm T. A medical worker holds the start end portion 159 of the armband portion 3 by hand and winds the armband portion 3 around the upper arm T along the R1 direction. At this time, the air bag 40 for detecting arterial pulsation is positioned according to the position of the artery of the upper arm T, so that the air bag 40 for detecting arterial pulsation can be accurately positioned with respect to the artery of the upper arm T. .
As a result, when the medical staff wraps the armband portion 3 around the patient's upper arm T, the second surface portion 50B comes into direct contact with the bare skin of the upper arm T and exhibits water absorption, toughness and flexibility. However, the air bag 40 for detecting arterial pulsation can be prevented from being displaced from the artery of the upper arm T.

As shown in FIG. 9 (B), the medical worker holds the terminal portion 169 of the armband portion 3 by hand and wraps the armband portion 3 around the upper arm T along the R2 direction. As shown, the female member 62 of the hook-and-loop fastener described above is detachably attached to the male member 61 of the hook-and-loop fastener. Since the female member 61 of the hook-and-loop fastener and the male member 62 of the hook-and-loop fastener are detachably engaged, the arm band portion 3 can be directly wound around the bare skin of the upper arm T and fixed so as not to be displaced.
In this case, the air that is to remain in the arm winding portion 96 shown in FIGS. 5A and 5B can be pushed out of the arm winding portion 96 using the through-hole 98. For this reason, since the arm winding portion 96 does not cause unnecessary swelling due to residual air, the arm band portion 3 can be reliably and easily wound so as to be in close contact with the upper arm T.

Next, as shown in FIG. 1, the medical staff presses the power switch 9 shown in FIG. 3 and the mode switch 10 while the armband 3 is held in the correct posture with respect to the upper arm T. Select the desired mode with.
As shown in FIG. 2, by repeating the operation of holding and releasing the air balloon 5 while supporting the extension portion 14 with the finger of the hand H, the air from the air balloon 5 is exchanged with the piping in the sphygmomanometer body 2. Air is sent through the

tubes

6 and 7 into the air bag 20 for ischemia and the air bag 40 for detecting arterial pulsation in the armband 3.

Accordingly, the pressure sensor 110 shown in FIG. 4 can accurately detect the fluctuation of the air pressure in the air bag 40 for detecting arterial pulsation, so that the blood pressure can be accurately measured. The air bag 20 for ischemia and the air bag 40 for detecting arterial pulsation can apply pressure to the upper arm T side, which is the inner side in the radial direction, and the pressure generated by the ischemic air bag 20 and arterial pulsation are detected. The pressure generated by the air bag 40 can be applied to the upper arm T without escaping to the outside of the armband portion 2, and accurate blood pressure measurement can be performed.

FIG. 10 shows an example in which the pressure applied to the upper arm T by the ischemic bladder 20 changes with time.
Air is sent into the air bag 20 for detecting ischemia and the air bag 40 for detecting arterial pulsation shown in FIG. 4 by repeating the operation of grasping and releasing the air balloon 5 shown in FIG. Therefore, as shown in FIG. 10, the pressure in the air bag 20 for ischemia in the armband portion 3 increases during the pressure increase period t1. In the pressure increase period t1, the control unit 100 in FIG. 4 determines that the pressurization is currently being performed, and instructs the drive unit 113 to close the electromagnetic valve 116. And the operation | movement which a medical worker grasps or separates the air balloon 5 is stopped, and pressurization is complete | finished.

Since the air balloon 5 is used, the pressure naturally decreases a little during the natural decompression period t2 in FIG. The controller 100 waits for the natural pressure reducing period t2, and then determines that the pressure detected by the pressure sensor 110 in FIG. 4 is in a reduced pressure state during the optimum speed pressure reducing period t3. The unit 113 is commanded to open the electromagnetic valve 116 so that the pressure reduction speed becomes a predetermined value. As a result, the pressure in the air bag 20 for ischemia in the armband 3 is reduced, and during this decompression, the control unit 100 shown in FIG. 4 receives a maximum blood pressure value (SYS) by a signal from the pressure sensor 110. And a minimum blood pressure value (D1A) and a pulse value are acquired. Thereafter, during the exhaust period t4, the control unit 100 in FIG. 4 operates the forced exhaust valve 117 to force the air in the air bag 20 for ischemia in the armband 3 and the air bag 40 for detecting arterial pulsation. Evacuate to eliminate pressure.

Thus, as shown in FIG. 8, when the arm band portion 3 is wrapped around the upper arm T and air is put into the arm band portion 3 to pressurize the upper arm T, the first side which is the outer surface side of the arm band portion 3 is used. A plurality of three-dimensionally formed portions 500 of the face portion 50A extend along the periphery of the upper arm T. When the three-dimensionally formed portions 500 of the first surface portion 50A extend along the peripheral direction of the upper arm T, the second surface portion 50B on the inner surface side of the armband portion 3 is stretched by the tension of the first surface portion 50A on the outer surface side. Thus, it does not move along the peripheral direction of the upper arm T. For this reason, the 2nd surface part 50B of the inner surface side of the armband part 3 moves, and a bending part does not arise in the location with the armband part 3. FIG. That is, when the armband portion 3 is wound around the upper arm T, there is no difference between the length of the first surface portion 50A and the length of the second surface portion 50B, so that the second surface portion 50B on the inner surface side of the armband portion 3 is conventionally generated. No wrinkles due to the bent parts.
For this reason, when wrinkles are generated on the inner surface side of the armband part 3, a part of the upper arm skin is pulled together with the inner surface of the armband part 3, and a phenomenon that a part of the upper arm skin is drawn into the wrinkles can be prevented. Therefore, the patient does not feel uncomfortable when measuring blood pressure, and internal bleeding does not occur in the upper arm.

In addition, after the blood pressure is measured, the medical staff may remove the armband 3 from the patient's upper arm T in the order of FIGS. 9C, 9B, and 9A. That is, as shown in FIG. 9C, the medical worker holds the end portion 169 of the armband portion 3 by hand and peels the end portion 169 of the armband portion 3 along the R3 direction. Accordingly, as shown in FIG. 9B, the female member 62 of the surface fastener on the terminal end 169 side of the armband portion 3 is peeled off from the male member 61 of the surface fastener on the start end portion 159 side of the armband portion 3. Can do. Then, as shown in FIG. 9 (B), the medical worker holds the starting end portion 159 of the armband portion 3 with his hand and separates it from the upper arm T in the R4 direction, as shown in FIG. 9 (A). The band 3 can be easily removed from the upper arm T.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.
FIG. 11 shows a second embodiment of the present invention. FIG. 11A shows an example of the first surface portion 190A and the second surface portion 190B constituting the main body member 80A of the armband portion 3A of the second embodiment of the present invention. FIG. 11B shows a state in which the armband portion 3A of the second embodiment of the present invention is attached to the upper arm T. The armband portion 3A is connected to the sphygmomanometer body portion 2 shown in FIG.
The arm band 3A shown in FIG. 11B is used particularly when the upper arm T is thicker than the upper arm of a standard patient, and the arm band 3 has a shoulder side length that is longer than the hand side length. It is getting bigger. A patient whose upper arm T is thicker than the upper arm of a standard patient is that the peripheral length on the shoulder side of the upper arm T and the peripheral length on the finger side of the upper arm T are the peripheral length on the shoulder side of the normal patient's upper arm T and the upper arm. It is a person who is larger than the peripheral length of T on the finger side.

In order to obtain the shape of the armband portion 3 used for such a patient with a thick upper arm T, the first surface portion 190A and the second surface portion 190B are both formed in a fan shape as shown in FIG. Yes. Moreover, the width K1 of the first surface portion 190A in the V direction is the same or slightly larger than the width K2 of the width second surface portion 190B in the V direction. The circumferential length J1 in the Y direction of the first surface portion 190A is larger than the circumferential length J2 in the Y direction of the second surface portion 190B. That is, the length along the peripheral direction of the upper arm T of the first surface portion 190A is set to be longer than the length along the peripheral direction of the upper arm T of the second surface portion 190B.
As shown in FIG. 11B, the first surface portion 190A is fixed to the second surface portion 190B by high frequency fusion in the same manner as the armband portion 3 shown in FIG. A plurality of three-dimensionally formed portions 600 are formed. The three-dimensional forming portion 600 is also referred to as a three-dimensional sewing portion.

As a result, when the armband portion 3 is wound around the upper arm T, and the air is applied to the armband portion 3 to pressurize the upper arm T, the armband portion 3 can be wound as a conical cylindrical body. Even if there is, blood pressure can be measured by wrapping the armband. A plurality of three-dimensionally formed portions 600 of the first surface portion 50 A on the outer surface side of the armband portion 3 extend along the peripheral length of the upper arm T. For this reason, when the three-dimensionally formed portions 600 of the first surface portion 50 A extend, the second surface portion 50 B on the inner surface side of the armband portion 3 moves and a bent portion is generated at a location where the armband portion 3 exists. Absent. That is, when the armband portion 3 is wound around the upper arm T, there is no difference between the length of the first surface portion 50A and the length of the second surface portion 50B, so that the second surface portion 50B on the inner surface side of the armband portion 3 is conventionally generated. No wrinkles due to the bent parts. For this reason, even if it is the thick upper arm T, the phenomenon that a part of skin of the upper arm is drawn into wrinkles can be prevented. For this reason, the patient does not feel uncomfortable when measuring blood pressure, and internal bleeding does not occur in the upper arm.

A sphygmomanometer 1 according to an embodiment of the present invention is a sphygmomanometer that has an arm band part and measures blood pressure by winding the arm band part around the upper arm of a person to be measured and pressurizing the arm band part. A body member having an air bag for ischemia for isolating the upper arm by supplying the body, and the body member has an outer first surface portion and a first surface portion, and has a second surface portion in contact with the upper arm. The air bag is formed by the first surface portion and the second surface portion, and the length along the peripheral direction of the upper arm of the first surface portion is longer than the length along the peripheral direction of the upper arm of the second surface portion. The first surface portion is configured to be extendable in the length direction along the peripheral direction of the upper arm.
Thereby, since the first surface portion is formed to extend from the second surface, when the arm band portion is wound around the upper arm and the upper arm is pressed, the first surface portion which is the outer surface side of the arm band portion is It extends along the circumferential direction of the. By extending the first surface portion, the second surface portion on the inner surface side of the armband portion does not move along the peripheral direction of the upper arm due to the tension of the first surface portion on the outer surface side, so there is an armband portion. There are no bent parts in the area. For this reason, when pressurizing the upper arm with the armband part, it is possible to prevent wrinkles from occurring on the inner surface side of the armband part, so that the patient does not feel uncomfortable during blood pressure measurement and causes internal bleeding in the upper arm There is no fear.
The arm band portion is disposed in the air bag for ischemia of the main body member, and includes an air bag for detecting arterial pulsation for detecting pulsation of the artery of the upper arm by supplying air.
As a result, even the armband portion having the air bag for ischemia and the air bag for detecting arterial pulsation is formed so that the first surface portion extends from the second surface. When the upper arm is wound and the upper arm is pressed, the first surface portion, which is the outer surface side of the arm belt portion, extends along the circumferential direction of the upper arm. By extending the first surface portion, the second surface portion on the inner surface side of the armband portion does not move along the peripheral direction of the upper arm due to the tension of the first surface portion on the outer surface side, so there is an armband portion. There are no bent parts in the area.

Thereby, since the 1st surface part is formed in three dimensions, when the arm belt part is wrapped around the upper arm and the upper arm is pressurized, the first surface part which is the outer surface side of the arm belt part is along the peripheral direction of the upper arm. It grows. By extending the first surface portion, the second surface portion on the inner surface side of the armband portion does not move along the peripheral direction of the upper arm due to the tension of the first surface portion on the outer surface side, so there is an armband portion. There are no bent parts in the area. For this reason, when pressurizing the upper arm with the armband part, it is possible to prevent wrinkles from occurring on the inner surface side of the armband part, so that the patient does not feel uncomfortable during blood pressure measurement and causes internal bleeding in the upper arm There is no fear.

Since the first surface portion and the second surface portion are fixed by fusion, the first surface portion and the second surface portion can be easily fixed by fusion so that air does not leak from the air bag for ischemia.
Since the first surface portion and the second surface portion are both formed in a rectangular shape, the patient can measure the blood pressure by simply stacking and fixing the rectangular first surface portion and the rectangular second surface portion, which are simple shapes. It does not feel uncomfortable and eliminates the possibility of internal bleeding in the upper arm. Blood pressure can be measured by wrapping the armband.
Since both the first surface portion and the second surface portion are formed in a fan shape, the armband portion can be wound in a conical shape. There is no risk of uncomfortable feeling during blood pressure measurement, and there is no risk of internal bleeding in the upper arm. Blood pressure can be measured by wrapping the armband.

It has a blood pressure monitor body connected to the armband air bag for ischemia and an air bag for detecting arterial pulsation using a tube. The blood pressure monitor body is attached to the housing and the housing. , And a balloon for sending air through the tube to the air bag for ischemia and the air bag for detecting arterial pulsation. For this reason, in a state where the medical worker holds the air balloon with one hand, the medical worker can wear it while easily positioning the armband portion on the upper arm with only the other hand.

The present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the claims.
In the illustrated example, the male member 61 of the hook-and-loop fastener 60 is one member of the hook-and-loop fastener and is disposed in the blood-insulating air bag 20, and the female member 62 of the hook-and-loop fastener 60 is the other member of the hook-and-loop fastener and the arm winding portion. 96. However, the present invention is not limited to this, and conversely, the female member of the hook-and-loop fastener 60 is one member of the hook-and-loop fastener and is disposed in the air bag 20 for ischemia, and the male member of the hook-and-loop fastener 60 is the other member of the hook-and-loop fastener.
