JP2003-313228A

  However, the technology of Patent Document 1 is a computer two-dimensional display / analysis system that uses a computer to give a visual sense of blood pressure values, which is not only a visual experience, but also a large-scale system.

  The present invention solves the above-described problems. The user can easily feel the blood pressure equivalent pressure indicated on the barometer by using, for example, the grip strength of his / her hand. An object of the present invention is to provide a blood pressure feeling machine and a blood pressure feeling method that can be realized with the body without any problems.

In order to achieve the above object, the gist of the invention described in claim 1 is that a flexible cylindrical hollow body is formed by providing a flexible flat hollow body and supplying air into the hollow body. A sensor (1), a tube (2) extending from the sensor and connected to the hollow body of the sensor, and a barometer (3) connected to the tube to measure the internal pressure of the sensor And a blower (4) that is connected to the tube and can supply gas into the hollow body of the real sensor, and is characterized in that a pressure range corresponding to blood pressure can be displayed by the barometer. There is a blood pressure sensor.
The gist of the invention described in claim 2 is to use a blood pressure sensor in which an actual feeling device (1) that is blown into a hollow body and has elasticity is connected to a barometer (3) through a tube (2).

  Hereinafter, the blood pressure feeling machine and the blood pressure feeling method according to the present invention will be described in detail. 1 to 7 show one embodiment of the blood pressure sensor according to the present invention. FIG. 1 is an overall perspective view thereof, FIG. 2 is an exploded perspective view of the sensor, and (b) is filled with gas in the hollow body. FIG. 3 and 4 are perspective views of a blood pressure sensor according to another embodiment, and FIGS. 5 to 7 are perspective views of a sensor according to another embodiment.

(1) Blood pressure sensor The blood pressure sensor includes a sensor 1, a tube 2, a barometer 3, and a blower 4. The real sensation device 1 is a bag-like body in which a flexible hollow hollow body 1a is formed by providing a flexible flat hollow body 1a and inflating by sending air into the hollow body 1a.

  The actual sensation device 1 includes a hollow body 1a and a cloth bag 1b. The hollow body 1a is a rubber sac that is made of rubber and has flexibility, and only the connecting portion of the tube 2 is opened. The shape of the hollow body 1a made of rubber thin skin is a flat air bag as shown in FIG. 2 (a) before air is put into the hollow body 1a, but the hollow body 1a is filled with air. As a result, the air bag expands into the hollow cylindrical body as shown in FIG. The hollow body 1a is formed into a closed and bottomed hollow cylindrical body 1a with a cylindrical portion 11 and circular bottom portions 10 on both end faces thereof, and the tube 2 is connected to the circular bottom portion 10 thereof.

The cloth bag 1b is a cloth bag-like body that is attached to the cylindrical surface of the hollow body 1a. The cloth bag 1b is a long rectangular bag-like body as shown in FIG. 2 (a), and has a size capable of covering the hollow body 1a. An opening 17 serving as a hollow body accommodating port is provided at one end of the cloth bag 1b, and a tube through hole 19 is opened at the other end. The opening 17 can be closed with a fastener 18 after the hollow body 1a is stored in the cloth bag 1b. If the tube 2 is taken out from the through hole 19 and the fastener 18 is closed, the cloth bag 1 b is covered with the hollow body 1. When the hollow body 1a as shown in FIG. 2 (a) in the flat state with the air removed is stored in the cloth bag 1b, the air is sent into the hollow body 1a using the blower 4 as shown in FIG. 2 (b). The actual sensation device 1 swells with elasticity. Here, since a pressure corresponding to blood pressure is applied to the hollow body 1a, the elastic hollow body 1a may exceed the elastic restoring force when the pressure is applied unless the rubber hollow body 1a has a necessary thickness. If only the hollow body 1a is used, the thickness must be increased to withstand the pressure. On the other hand, if the thin skin thickness of the hollow body 1a is increased, the elasticity of the actual feeling device 1 is weakened and the function of realizing blood pressure is impaired. For this reason, the hollow body 1a of the present embodiment is thinned to some extent so as to maintain elasticity and resilience by filling the gas, and expands beyond the elastic restoring force when pressure is applied. This problem is solved by covering the hollow body 1a with the cloth bag 1b. The cloth bag 1b keeps the expansion more than necessary in a constant shape.
An actual sensor 1 (hollow body 1a to which a cloth bag 1b is attached) formed in an elastic cylindrical hollow body 1a by filling a gas in the hollow body 1a is in a flat state in which air is evacuated. B × width A is about 110 mm × about 220 mm. By putting air into the hollow body 12, the cylindrical real device 1 having a diameter D × length L of about 70 mmφ × 220 mm is obtained. The cylindrical real sensor 1 is used for ease of grasping, and the size of the tube is realized by a user such as a patient who actually holds the real sensor 1 with both hands (pressure corresponding to blood pressure). This is to facilitate the work of experiencing (value).

The tube 2 is a rubber tube that is electrically connected to the inside of the hollow body 1 a of the real device 1 and extends from the real device 1. The tube 2 may be integrally formed with the hollow body 1a, or may be formed separately from the hollow body 1a, and then fixed to the hollow body 1a and extended from the hollow body. . As shown in FIG. 1, the tube 2 extended from the hollow body 1a branches in two on the way through a three-way connector (Y-shaped connector) 21, and the barometer 3 is attached to the tip of one branch point. The blower 4 is attached to the tip of another branch point.
In this embodiment, only one tube 2 is extended from the pressure sensor 1, which is different from the case where two tubes 2 are extended from the manchette of the sphygmomanometer. The sphygmomanometer requires fine adjustment of the amount of air sent from the blower to the manchette, and in order to improve the workability, two tubes had to be extended from the manchette. It can be used simply by extending one to one tube.

  The barometer 3 is a pressure gauge for measuring the internal pressure of the real sensor 1 and is connected to the tip of the main tube 2 extending from one branch point of the tube 2 here. In the present embodiment, the barometer 3 uses a Rivaroch type mercury sphygmomanometer 3a. The height of the mercury column is used for the display part of the mercury sphygmomanometer 3a, and blood pressure is still displayed in mmHg as an exception of the international unit system for historical reasons. The barometer 3 can measure and display a pressure range corresponding to blood pressure (for example, a range of 0 to 300 mmHg). As the barometer 3, an aneroid sphygmomanometer 3b or the like can be used instead of the mercury sphygmomanometer 3a.

  The blower 4 can be connected to the tube 2 to supply gas into the hollow body 1a of the real sensor 1, and here it is connected to the distal end of the branch tube 2 extending from another branch point of the tube 2. . The blower 4 of the present embodiment uses a known insufflator 4a used in a general blood pressure measuring instrument. The air feeding element 4a is a ball-shaped body that sends air. By grasping this, the air feeding element 4a can send air to the real sensor 1. Air can be sent to the actual feeling device 1 by the blower 4 to increase the internal pressure of the hollow body 1a related to the actual feeling device 1 to a pressure range corresponding to the blood pressure. Reference numeral 7 denotes an air vent cock. When the amount of air sent to the real sensor 1 is too large, the air vent cock 7 exhausts air to adjust the real sensor 1 to a predetermined pressure. The air vent cock 7 is also used when the blood pressure sensor is finished and the air in the sensor 1 and the tube 2 is exhausted when it is cleaned.

  The blower 4, the sensation device 1, and the barometer 3 are electrically connected, and the conductive space is a closed system except when the air is extracted by the air vent cock 7. If outside air is taken in from the blower 4 and air is sent into the system, the pressure of the entire system rises because the blower 4, the sensation device 1 and the barometer 3 are connected via the tube 2 as shown in FIG. To do. The pressure is visible with the barometer 3.

FIG. 3 shows another embodiment of a blood pressure sensing machine in which a manchette 6 is further connected to the tube 2 of FIG. The portion of the tube 2 that connects the three-way connector (Y-shaped connector) 21 and the barometer 3 branches through the three-way connector (T-shaped connector) 22, and the manchette 6 is attached to the tip of the branch. The Manchette 6 is a well-known product used for blood pressure measurement and contains a rubber bag. By inflating the rubber bag, the artery is closed to generate Korotkoff sounds. A switching valve 52 is provided near the manchette of the tube 2 extending from the manchette 6, and a switching valve 51 is provided near the actual sensor of the tube 2 extending from the actual sensor 1. By closing the switching valve 52 and opening the switching valve 51, the actual sensor 1, the barometer 3 and the blower 4 are electrically connected, and the pressure indicated by the barometer 3 by holding the actual sensor 1 by hand, that is, blood pressure equivalent While the value can be experienced, by closing the switching valve 51 and opening the switching valve 52, the manchette 6, the barometer 3 and the blower 4 are connected to each other, and a blood pressure can be measured by using a known blood pressure instrument.
FIG. 4 shows a blood pressure sensation machine according to another embodiment using an aneroid sphygmomanometer 3b in the barometer 3 of FIG.

  FIG. 5 shows another embodiment product in place of the actual feeling device 1 of FIG. 1, in which the actual feeling device 1 is formed by forming the fiber cord 14 in a mesh shape and covering the both sides with compounded rubber. By embedding the mesh fiber cord 14 in the rubber hollow body 1a, the hollow body alone functions as the actual sensor 1 even when the pressure is increased to a pressure range corresponding to blood pressure. FIGS. 6 and 7 are perspective views of another embodiment of the actual feeling device in place of the actual feeling device 1 of FIG. 1. Both of the actual feeling devices 1 are formed by supplying air into the hollow body 1a to form a resilient cylindrical hollow body. Show. FIG. 6 shows the real sensor 1 in which the raised portions 131 are formed at both ends of the cylindrical portion, and FIG. 7 shows the real device 1 in which the concave portion 132 is formed on the cylindrical surface of the cylindrical portion. The raised portion 131 and the recessed portion 132 play a role of slipping the hand that holds the real sensor 1.

(2) Blood pressure actual feeling method Next, the blood pressure actual feeling method of the present invention will be described. The blood pressure realization method uses a blood pressure realization machine in which the realization device 1 which is supplied to the hollow body 12 and is inflated with elasticity is connected to the barometer 3 through the tube 2, and after the realization device is inflated, the realization device 1 This is a method in which the pressure value of the barometer 3 rises according to the gripping force by gripping so as to be elastically compressed and deformed, and a blood pressure equivalent pressure is realized.
The blood pressure feeling method is performed as follows using, for example, the blood pressure feeling machine of FIG. First, air is sent by the blower 4 to the sensation device 1 in a state where air has been removed, and the sensation device 1 is inflated until the barometer 3 shows a pressure value of about 80 mmHg. After this state, the blood pressure equivalent pressure is sensed using this blood pressure sense machine. Specifically, a person who wants to experience blood pressure with a blood pressure sensor senses and grasps the cylindrical part 11 of the sensor 1 with his / her hand. By grasping with the hand, the actual feeling device 1 is elastically compressed and deformed, and the volume of the hollow body 12 is reduced. Since the actual sensor 1, the barometer 3 and the blower 4 are electrically connected and the conductive space is closed, the pressure in the system increases as the volume of the actual sensor 1 decreases. The barometer 3 shows a numerical value of 150 mmHg or 200 mmHg, for example, according to the degree of the gripping force to be elastically compressed. When the barometer 3 reaches 150 mmHg, for example, the pressure (reaction force) of that value is transmitted to the hand holding the real sensor, and a blood pressure equivalent pressure of 150 mmHg can be realized. If it becomes 200 mmHg, the pressure (reaction force) of the numerical value will be transmitted to the hand holding the real sensor 1, and a blood pressure equivalent pressure of 200 mmHg can be realized.

(3) Effect According to the blood pressure sensor and the blood pressure sensor method configured as described above, by inflating the sensor 1 to a pressure of about 80 mmHg using the blower 4, the sensor 1 is grasped and gripped by the hand. The pressure corresponding to the blood pressure can be easily experienced through the user's own hand. Since the actual feeling device 1 inflated to a predetermined pressure is elastic, by grasping and grasping it by the hand, the actual feeling device 1 is elastically deformed and the volume of the actual feeling device is reduced. Due to this volume reduction, the blower 4, the sensation device 1 and the barometer 3 are connected to each other through the tube 2 and are closed, so that the pressure of the entire system rises. If the actual device 1 is held firmly, the pressure value of the barometer 3 increases to 150 mmHg and further 200 mmHg, and the internal pressure is directly transmitted to the user's hand by the resilience and repulsive force of the actual device 1. Since the real sensor 1 is connected to the barometer 3 via the tube 2, the user can check the internal pressure of the real sensor 1 with the numerical value indicated by the barometer 3. Patients with high blood pressure can easily experience the pressure of high blood pressure using this blood pressure sensor, and can fully understand the pathophysiology and therapeutic effects of hypertension. It can be expected that patients with high blood pressure will be able to tackle treatment without thinking lightly or worrying too much. The blood pressure sensation machine according to the present invention helps to acquire health care easily.
On the other hand, the doctor can easily explain the high blood pressure to the patient and confirm the treatment effect by using the blood pressure sensor. In addition, it will be a useful tool for explaining and understanding high blood pressure at workshops. In addition, once the sensation device 1 is inflated to a predetermined pressure and set, the blood pressure sensation device can be experienced any number of times as long as it does not evacuate the gas (air) with the air vent cock 7, so there is no troublesomeness in use. It can be experienced even if people change, and it will be an excellent one that can be handled by any number of people. If it is installed in a waiting room of a hospital or the like, it has a great effect such as a corner where you can easily feel the pressure of blood pressure.

Further, the blood pressure actual feeling machine has a relatively simple structure, and unlike the invention technique of Patent Document 1, it can realize cost reduction.
Furthermore, if the blood pressure sensor as shown in FIG. 3 is used, it also becomes an instrument for measuring blood pressure, and it plays a dual role by itself. Since switching from a blood pressure measuring device to a device that realizes blood pressure, or vice versa, can be performed only by operating the switching valves 51 and 52, the blood pressure feeling device is excellent in workability.

  The present invention is not limited to the one shown in the above embodiment, and various modifications can be made within the scope of the present invention depending on the purpose and application. The shape, size, and the like of the actual sensor 1, the tube 2, the barometer 3, the blower 4, the switching valve 5, the manchette 6, and the air vent cock 7 can be appropriately selected according to the application.
