Description

Sphygmomanometer and method for manufacturing arm band part of sphygmomanometer

The present invention relates to a sphygmomanometer that wraps an armband part and measures a patient's blood pressure, and a method for manufacturing the armband part of the sphygmomanometer.

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).

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.
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.
As shown in FIG. 1, the sphygmomanometer 1 measures a patient's blood pressure by pressurizing an air bag in an armband attached to a patient's upper arm T by a manual pressurization method by a medical staff such as a nurse. It can be carried out. This manual pressurization type sphygmomanometer 1 has an air balloon (pressurization unit) and a sphygmomanometer main body integrated, and a medical worker can pressurize the air balloon with one hand, Therefore, it is possible to measure blood pressure quietly even at night.

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 FIGS. 1 and 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. Is 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 balloon 5 is a pressurizing unit that can send air inside by a medical worker performing a pressurizing operation, and is made of a stretchable material. The air balloon 5 is a rubber balloon, for example.

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 can be turned on or off by the medical staff by pressing the power switch 9. 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, the medical staff repeats the operation of grasping and releasing the air balloon 5 while supporting the extension 14 with the fingers of the hand H, whereby the air from the air balloon 5 is converted into the blood pressure monitor main body 2. It can be supplied to the air bag for ischemia and the air bag for detecting arterial pulsation in the armband portion 3 through the inner pipe and the

tubes

6 and 7. Projections 4T are formed on both sides of the housing 4.

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 the air balloon 5 is operated to supply air, the previously measured maximum blood pressure value, minimum blood pressure value, and pulse value disappear, and the previous value display area 8E When the power switch 9 is pressed and the operation of the sphygmomanometer 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, preferably, a medical worker performs a pressurizing operation of the air balloon with one hand 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 dry battery (DC1.5V) ) Or only one AA rechargeable battery (DC1.5V). 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. The armband body member 80 includes a blood-insufficiency bladder 20 and an arm winding portion 96. 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. When a medical worker grasps or separates the air balloon 5, the air enters the ischemic air bladder 20 through the manifold 118, the branch portion 119, the conducting tube 120, the forced exhaust valve 117, and the tube 6. While being able to send in, air can be sent into the air bag 40 for detecting arterial pulsation through the manifold 118, the branch part 119, the manifold 121, the branch part 122, and the tube 7.

Next, a preferable example of the manufacturing method of the armband part 3 shown in FIG. 1 and a structure example of the armband part 3 will be described with reference to FIGS.
As shown in FIG. 1, the armband portion 3 is directly wound around the bare skin of the upper arm T of a patient. A detailed example of a method for manufacturing the armband portion 3 and a structural example of the armband portion 3 are shown in FIG. 5 to FIG.
The armband 3 has a double cuff type bladder consisting of an air bag for ischemia (large bag) and an air bag for detecting arterial pulsation (small bag). The outer fabric for covering the bladder is It does not have a so-called one-piece cuff structure. That is, the armband portion 3 is composed of one member including an air bag for ischemia (large bag) and an air bag for detecting arterial pulsation (small bag).

FIG. 5 is an exploded perspective view showing each member constituting the armband 3. FIG. 6 is a perspective view showing a manufacturing process of each member shown in FIG. FIG. 7 shows a structural example of the manufactured armband portion 3, FIG. 7A is a perspective view showing the inner surface side of the armband portion 3, and FIG. FIG. 7C is a perspective view showing the outer surface side, and FIG. 7C is a view showing a cross section taken along line AA of the armband portion 3 shown in FIG. 7A.

First, before describing a preferable method of manufacturing the armband portion 3 with reference to FIGS. 5 to 7, characteristics of each member constituting the armband portion 3 will be described with reference to FIGS. 5 and 6.
As shown in FIG. 5, the armband portion 3 includes a main body member forming sheet 50, a sheet-like contact member 51, a sheet-like sealing member 52, a male member 61 of the hook-and-loop fastener 60, and a hook-and-loop fastener 60. Female member 62 and an air bag (small bag) 40 for detecting arterial pulsation. 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.

The main body member forming sheet 50 shown in FIG. 5 is a rectangular sheet, and has a rectangular first surface portion 50A and a rectangular second surface portion 50B. The first surface portion 50A and the second surface portion 50B are separated by a center fold line 59 that is parallel to the longitudinal direction T. The first surface portion 50A and the second surface portion 50B are folded in the direction of the arrow RR shown in FIG. 6 along the center fold line 59 and overlap each other, thereby forming a rectangular main body member 80 as shown in FIG. .

As shown in FIG. 5, the main body member forming sheet 50 preferably has a double structure having a first sheet layer 71 and a second sheet layer 72. 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, and 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.

A sheet-like contact member 51 shown in FIG. 5 includes a first layer 51A and a second layer 51B. The first layer 51A is, for example, nylon, and the second layer 51B is, for example, a urethane resin, but is not limited thereto. The sheet-like sealing member 52 is, for example, a urethane resin, but is not limited thereto.
As shown in FIG. 5, a cut portion 50 C is formed in the second surface portion 50 B of the main body member forming sheet 50. A lid member 50K is formed in the cut portion 50C by cutting the three

side portions

50F, 50G, and 50H. By opening the lid member 50K, an air bag 40 for detecting arterial pulsation is inserted inside the lid member 50K. Thereby, the air bag 40 for detecting arterial pulsation is positioned between the first surface portion 50A and the second surface portion 50B of the main body member forming sheet 50.

As shown in FIG. 6, a thin support plate 42 made of metal or plastic is fixed to an air bag 40 for detecting arterial pulsation via a double-sided tape 41 inside an air bag member 40A. As described above, since the support plate 42 is arranged, a large pressure fluctuation in the ischemic bladder 20 is not transmitted to the arterial pulsation detecting bladder 40. 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 42 is disposed, the air bag 40 for detecting arterial pulsation has a function that can be brought into close contact with the bare skin of the upper arm T of the patient.
As shown in FIGS. 5 to 6, the abutting member 51 is fixed to the inner surface 50N of the second surface portion 50B of the main body member forming sheet 50 by, for example, high frequency fusion. Accordingly, the air bag 40 for detecting arterial pulsation is covered with the abutting member 51 in a state where the air bag 40 for detecting arterial pulsation is inserted inside the lid member 50K. For this reason, the air bag 40 for detecting arterial pulsation is built in the air bag 20 for ischemia.

Here, the preferable example of the manufacturing method of the preferable armband part 3 is demonstrated. FIG. 8 shows an example of the manufacturing process of the armband portion 3.
As shown in FIGS. 8A and 5, the male member 61 of the surface fastener 60 is disposed on the outer surface 50M of the first surface portion 50A of the main body member forming sheet 50, and the male member 61 is disposed on the first surface portion 50A. On the other hand, it is firmly attached by sewing using the thread 80 shown in FIG. Thus, fixing the male member 61 to the first surface portion 50A by sewing can improve the attachment strength of the male member 61 to the first surface portion 50A as compared with the case of fixing by fusion. This is because it can.

However, since the thread 80 passes through the male member 61 and the first surface portion 50A of the surface fastener 60 by sewing with the thread 80, the through-hole 80R is opened, and in this state, the outer side 61P of the male member 61 and the first Air passes between the surface portion 50A and the inner surface 50S side. Therefore, in order to prevent air from passing through the through-hole 80R, as shown in FIG. 8B, the sheet-like sealing member 52 is fixed to the inner surface 50S of the first surface portion 50A by, for example, high-frequency fusion. Is done.
Thereby, the sheet-like sealing member 52 can block the through-hole 80R through which the thread 80 has passed, so that air passes between the outer side 61P of the male member 61 and the inner surface 50S side of the first surface portion 50A. Can be surely prevented. As described later, the use of the sheet-like sealing member 52 to secure the air tightness (or liquid tightness) of the first surface portion 50A so that air does not pass through will be described later with reference to FIG. This is to ensure the sealing property of the air bag 20 for ischemia shown in FIG.

Next, as shown in FIGS. 5 to 6, the air bag 40 for detecting arterial pulsation is placed inside (on the upper surface side in FIG. 5) the lid member 50 K of the second surface portion 50 B of the main body member forming sheet 50. . As shown in FIGS. 8C and 8D, the contact member 51 is placed on the inner surface 50N of the second surface portion 50B and fixed to the inner surface 50N by, for example, high frequency fusion.
Moreover, the lid member 50K is fixed to the abutting member 51 by, for example, high frequency fusion 50R. Thus, the air bag 40 for detecting arterial pulsation can be sealed airtight (liquid tight) by the lid member 50K and the contact member 51, and air can pass between the outer side 50P and the inner side 51P. There is no. Thus, as described later, the air for ischemia shown in FIG. 7A is to secure the sealing performance so that air does not pass through the region of the lid member 50K and the air bag 40 for detecting arterial pulsation. This is to ensure the sealing performance of the bag 20.
In the manufacturing process of the main body member 80 described with reference to FIGS. 5, 6, and 8, the manufacturing order can be arbitrarily changed.

Next, FIG. 9 shows an example of the high

frequency fusion portions

90, 91, 92, 93, 94 in the main body member 80.
The first surface portion 50A and the second surface portion 50B shown in FIG. 6 are folded in the direction of the arrow RR shown in FIG. 6 by the bent portion 95 along the center fold line 59, and overlap each other. As shown in (B), a rectangular main body member 80 is formed. When the main body member 80 is formed, as shown in FIGS. 7A and 7B, FIGS. 9A and 7B, the first surface portion 50A and the second surface portion 50B are In order to seal, high-frequency fused

portions

90, 91, 92, 93, and 94 are formed.

Thus, in the main body member 80, the high-frequency fused

portions

90, 91, 92, 93, 94 and the bent portion 59 are divided into the main body member 80, the ischemic air bag 20, and the arm winding portion 96. The blood-insufficiency air bag 20 is hermetically sealed by a bent portion 95 and high-frequency fused

portions

90, 91, 94. The tube 6 is airtightly connected to the tube connection hole 20 H of the ischemic air bladder 20. FIG. 10 is a cross-sectional view taken along the line BB showing the vicinity of the air bag 40 for detecting arterial pulsation and the air bag 20 for ischemia in FIG. As shown in FIG. 10, the air bag 40 for detecting arterial pulsation is disposed so as to overlap the air bag 20 for ischemia using a contact member 51.
Returning to FIG. 7 and FIG. 9, the arm winding portion 96 is formed to be sealed by a bent portion 95 and high

frequency fusion portions

92, 93, 94.

Next, as shown in FIG. 7A and FIG. 9A, in the arm winding portion 96, the female member 62 of the hook-and-loop fastener 60 is sewn using the thread 99 as shown in FIG. The second surface portion 50B is attached to the outer surface 50Q. Thus, the reason why the female member 62 is fixed by sewing 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. 9 (A) is different from the air bag 20 for ischemia and is a portion where air does not flow in, that is, a portion which does not expand when the upper arm is pressurized. In order to wind it securely, it is desirable to prevent air from entering the arm winding portion 96. However, when the main body member 80 is actually manufactured, in the main body member 80, the high-

frequency fusion portions

90, 91, 92, 93, 94 and the bent portion 95 are connected to the air bag 20 for ischemia and the arm winding portion 96. If it is formed so that it can be separated, 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. .
In addition, as an arm band part 3 shown to FIG. 7 (A), a different size can be prepared in consideration of a patient's arm circumference dimension. 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. 11 to 13.
FIG. 11 shows a state in which the arm band 3 is directly wound around the skin of the upper arm T of the patient. FIG. 12 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. 11, the medical staff wraps and fixes the armband portion 3 directly to the bare skin of the upper arm T of the patient as follows.
As shown in FIG. 11, 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. The side is applied from the lower side of the upper arm T. As shown in FIG. 12 (B), the medical staff holds the starting 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.

In addition, the air that is to remain in the arm winding portion 96 shown in FIGS. 7A and 7B is transferred to the outside of the arm winding portion 96 using the through hole 98 shown in FIG. Can be extruded. 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.
As shown in FIG. 12 (C), a 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. The female member 62 of the hook-and-loop fastener mentioned above is attached to 61 so that attachment or detachment is possible. 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.

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.
As a result, the pressure sensor 110 shown in FIG. 4 can accurately detect fluctuations in the air pressure in the air bag 40 for detecting arterial pulsation, so that accurate blood pressure measurement can be performed. 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. 13 shows an example in which the pressure applied to the upper arm T by the air bag 20 for ischemia changes with time.
Air is sent into the air bag 20 for ischemia and the air bag 40 for detecting arterial pulsation in the arm band 3 shown in FIG. 5 by repeating the operation of grasping and releasing the air balloon 5 shown in FIG. Therefore, as shown in FIG. 9, the pressure in the air bag 20 for ischemia in the armband 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 which is a rubber ball 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.

In addition, after the blood pressure is measured, the medical staff may remove the armband part 3 from the patient's upper arm T in the order of FIG. 12 (C), FIG. 12 (B), and FIG. 12 (A). That is, as shown in FIG. 12C, 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. 12B, 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. 12 (B), the medical worker holds the start 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. 12 (B). The part 3 can be easily removed from the upper arm T.

As described above, as shown in FIG. 7A, the air bag 20 for ischemia is formed by being sealed by the bent portion 95 and the high

frequency fusion portions

90, 91, 94. Moreover, the air bag 40 for detecting arterial pulsation can be sealed by the lid member 50K and the contact member 51, and air does not pass between the outer side 50P and the inner side 51P. Therefore, the air bag 20 for ischemia and the air bag 40 for detecting arterial pulsation are air-tight and liquid-tight. For this reason, since the armband part 3 can be disinfected with a disinfectant or can be washed with a cleaning liquid, the armband part 3 can be kept clean.

The sphygmomanometer 1 according to the embodiment of the present invention is a sphygmomanometer that has an arm band portion 3 and measures the blood pressure by winding the arm band portion 3 around the upper arm T of a subject to be pressurized. The arm band portion 3 is formed by folding a sheet-like member and hermetically sealing, and a body member 80 having a blood-insulating air bag 20 for blocking the upper arm T by supplying air, and a body member An air bag 40 for detecting arterial pulsation for detecting the pulsation of the artery of the upper arm T by supplying air is provided.
Therefore, the main body member 80 having the ischemic air bag 20 is formed by bending a sheet-like member and hermetically sealed, and the air bag 40 for detecting arterial pulsation is used for the ischemic air of the main body member 80. It is arranged in the bag 20. Therefore, an outer cloth for covering is not necessary, and the structure of the armband portion 3 can be simplified and the armband portion 3 can be easily wound around the upper arm T of the patient.

The main body member has a first surface portion and a second surface portion overlapping the first surface portion, and the air bag for ischemia is formed inside the first surface portion and the second surface portion, and air for detecting arterial pulsation The bag is placed inside the ischemic air bag by cutting out a part of the ischemic air bag and is kept airtight.
For this reason, the main body member has a first surface portion and a second surface portion that overlaps the first surface portion, and an air bag for hemostasis is formed inside the first surface portion and the second surface portion, for detecting arterial pulsation. The air bag is placed inside the air bag for ischemia by cutting out a part of the air bag for ischemia and is kept airtight. Thereby, the air bag for detecting arterial pulsation and the air bag for ischemia can be configured integrally. Therefore, it is easy to wash and clean the armband.

The main body member has one member constituting the surface fastener and the other member detachably attached to the one member, and the first surface portion side of the air bag for the hemostasis of the main body member is provided with the surface fastener.

A stop member is affixed.
For this reason, one member of the hook-and-loop fastener is fixed by sewing to the first surface portion side of the air bag for ischemia of the main body member, and a hole generated by sewing is closed on the inner surface of the first surface portion of the air bag for ischemia, A sheet-shaped sealing member for preventing passage of air between the outer surface and the inner surface of the first surface portion is attached. Thereby, one member of the hook-and-loop fastener is fixed by sewing, so that the mounting strength can be improved as compared with the case of fixing by fusion, and the air bag for ischemia has a through-hole formed by sewing. However, since the through hole can close the hole generated by sewing by the sheet-like sealing member, the airtightness (liquid tightness) of the air bag for ischemia can be ensured.

The air bag for detecting arterial pulsation is a sheet member attached to the inner surface of the second surface portion of the air bag for ischemia and a lid member formed by cutting out a part of the second surface portion of the air bag for ischemia It is kept airtight between the contact members.
For this reason, since the air bag for detecting arterial pulsation is airtightly held by the lid member and the sheet-like contact member, the airtightness (liquid tightness) of the air bag for ischemia can be ensured. .

The other member of the surface fastener is attached by sewing to the first surface portion and the second surface portion where the main body member overlaps.
For this reason, since the other member of the hook and loop fastener is attached to the first surface portion and the second surface portion where the main body member overlaps by sewing, the air for ischemia in the main body member is passed through the through-hole generated by the sewing. Since air in parts other than the bag can be extracted, air bleedability of parts other than the air bag for ischemia in the main body member can be ensured.

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, while a medical worker holds an air balloon with one hand, the medical worker can wrap the armband part with the other hand only while easily positioning the armband part on the upper arm. Can be improved.
