Description

  The present invention relates to an underwater sphygmomanometer for measuring the blood pressure of a human body in water.

  In general, underwater exercise such as swimming is recognized as one of the health methods, but 30% of AED (automated external defibrillator) use cases are related to seizures during underwater exercise. Results have also been reported suggesting that underwater exercise can be a health risk for patients with vascular disease. That is, it is one of the important issues in sports health medicine to know the blood pressure fluctuation in human water.

  However, the conventional non-invasive blood pressure monitor is generally composed of a blood pressure monitor main body and a cuff provided with a pressure bag and a microphone and is premised on measurement under atmospheric pressure. The actual situation is that it cannot be used for measuring blood pressure in water under conditions and under pressure by water pressure.

  The present invention has been made in view of the above-described conventional situation, and an object thereof is to provide an underwater sphygmomanometer that can normally measure blood pressure in water without being affected by water or water pressure. .

  The present inventor has conducted various studies to solve the above-mentioned problems, and as a result, a waterproof case that prevents contact between the sphygmomanometer main body and water and maintains the sphygmomanometer main body at water pressure and equilibrium pressure in water. It has been found that extremely good results can be obtained if it is used, and the present invention has been completed.

That is, in the present invention, the sphygmomanometer body is housed and installed in a waterproof case, and a sphygmomanometer cuff and a microphone provided with a pressure bag outside the waterproof case are disposed.
With increasing external pressure of the waterproof case at insidious to the internal pressure and the external pressure of the waterproof case by introducing air into equilibrium in a waterproof case, a regulator connectable with the air tank, waterproof case when flying The exhaust pipe having an exhaust valve for discharging the air in the waterproof case to the outside of the waterproof case as the external pressure decreases, and the measurement start lever for operating the measurement start button of the sphygmomanometer body are provided. The above-mentioned problem is solved by an underwater blood pressure monitor.

  If the underwater sphygmomanometer of the present invention is used, the sphygmomanometer body does not come into contact with water, and the internal pressure and the external pressure of the waterproof case are maintained in equilibrium, so that it is not affected by water or water pressure. Blood pressure can be measured normally.

  As a result, it is possible not only to collect basic data on blood pressure during underwater activities, but also to manage the health of participants in various underwater competitions and swimming schools, which can greatly contribute to the field of sports health medicine. .

The schematic explanatory drawing which shows the usage example of this invention underwater blood pressure meter. The schematic explanatory drawing which shows the air introduction operation example of a regulator.

  Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic configuration explanatory diagram of an underwater blood pressure monitor according to the present invention.
In FIG. 1, reference numeral 10 denotes a waterproof case, which includes a regulator 20, an exhaust pipe 30, and a measurement start lever 40. The material is not particularly limited as long as the material is waterproof.
A water receiving space 11 is formed below the waterproof case 10, in other words, below the sphygmomanometer body 50 housed and installed inside.

Regulator 20 With increasing external pressure of the waterproof case 10 at the time insidiously, in which the internal pressure and the external pressure of the waterproof case 10 by introducing automatic air into the waterproof case 10 in which the equilibrium, the diaphragm 21 And an air introduction pipe 23 provided with a valve 22 that opens and closes in conjunction with the deformation of the diaphragm 21, and the air introduction pipe 23 can be connected to the breathing air tank 100.

The exhaust pipe 30 discharges the air in the waterproof case 10 to the outside of the waterproof case 10 as the external pressure of the waterproof case 10 decreases at the time of rising, and the internal exhaust pipe part disposed in the waterproof case 10 31 and an external exhaust pipe portion 32 disposed outside the waterproof case 10, and when the internal pressure of the waterproof case 10 is higher than the external pressure in the connecting portion between the internal exhaust pipe portion 31 and the external exhaust pipe portion 32. An exhaust valve 33 that opens and closes when the internal pressure is equal to or lower than the external pressure is provided.
The internal exhaust pipe portion 31 is disposed so that the lower end 31 a thereof opens to the water receiving space portion 11 of the waterproof case 10.

The measurement start lever 40 operates the measurement start button 51 of the sphygmomanometer main body 50 housed and installed in the waterproof case 10 from the outside of the waterproof case 10, and one end thereof is pivotally attached to the outer wall of the waterproof case 10. A magnet (not shown) is attached to the other end that rotates up and down. On the other hand, above the measurement start button 51 of the sphygmomanometer main body 50 in the waterproof case 10, a vertical rotation bar 60 having a measurement start button operation convex portion 61 is disposed at a substantially central portion. One end of the vertical rotation bar 60 is pivotally attached to the inner wall of the waterproof case 10, and a magnet (not shown) is attached to the other end that rotates vertically on the measurement start lever 40 side.
With this configuration, when the measurement start lever 40 is pulled down, the vertical rotation bar 60 is also moved downward by the magnetic force of the magnet of the measurement start lever 40 and the magnet of the vertical movable bar 60, and the measurement start button operation convex portion 61 starts measurement. By pressing the button 51, the sphygmomanometer body 50 is switched on. As described above, since the operation of the measurement start button 51 is controlled by the magnetic force of the magnet, it is not necessary to form a hole in the waterproof case 10, so that there is no possibility of water intrusion.

70 is a sphygmomanometer cuff disposed outside the waterproof case 10, and a pressure bag 80 is mounted on the inside thereof. The pressure bag 80 is connected to the blood pressure monitor main body 50 in the waterproof case 10 through an air pipe 81 so that air can be introduced.
Reference numeral 90 denotes a sphygmomanometer microphone disposed outside the waterproof case, and is used by placing it inside the pressure bag 80 when measuring blood pressure. The sphygmomanometer microphone 90 is connected to the sphygmomanometer main body 50 in the waterproof case 10 through a cord 91 waterproofed with a tube or the like so that Korotkoff sounds can be transmitted.

  Next, a method of using the underwater blood pressure monitor according to the above embodiment will be described.

First, as shown in FIG. 2, the waterproof case 10 in which the sphygmomanometer body 50 is housed is installed and fixed to the outer wall of the breathing air tank 100, and the air introduction pipe 23 is connected to the breathing air tank 100. In this state, the measurement subject wears the breathing air tank 100.
Next, the sphygmomanometer cuff is wound around and fixed to the arm P of the measurement subject with the sphygmomanometer microphone 90 inside the pressurizing bag 80.
Incidentally, the valve 22 of the regulator 20 in such a state is closed because the internal pressure and the external pressure of the waterproof case 10 are in an equilibrium state as shown in FIG. The exhaust valve 33 of the exhaust pipe 30 is also closed.

  Next, when the breathing regulator 110 is attached to the mouth and submerged, as shown in FIG. 3B, the external pressure of the waterproof case 10 increases, so that the diaphragm 21 of the regulator 20 is deformed, and the deformation Since the valve 22 opens and the air introduction tube 23 opens, air is introduced from the breathing air tank 100 into the waterproof case 10.

  Next, when air is introduced into the waterproof case 10 until the internal pressure and the external pressure of the waterproof case 10 are balanced, the deformation of the diaphragm 21 returns to the original state, so that the state shown in FIG. The valve 22 is closed and the introduction of air is stopped. Even in this state, since the exhaust valve 33 of the exhaust pipe 30 is closed, water is prevented from entering the waterproof case 10.

  Next, if the measurement start lever 40 is operated in this state and the measurement start button 51 of the sphygmomanometer main body 50 is operated, the blood pressure of the subject under measurement is normally measured and recorded as in the atmosphere. The

  Next, when the air pressure rises after the blood pressure measurement, the external pressure of the waterproof case 10 decreases from the internal pressure, so that the exhaust valve 33 of the exhaust pipe 30 is opened by a large internal pressure, and the air in the waterproof case 10 flows from the internal exhaust pipe portion 31 to the external. When the exhaust pipe 32 is discharged to the outside of the waterproof case 10 and the internal pressure and the external pressure of the waterproof case 10 are balanced, the exhaust valve 33 is closed.

  If the water W enters the waterproof case 10 for some reason, the water receiving space 11 stores the water, so that contact between the blood pressure monitor main body 50 and water can be prevented. If the tire frame 21 is pushed, the valve 22 is opened, and air is introduced into the waterproof case 10 from the breathing air tank 100, the internal pressure of the waterproof case 10 becomes higher than the external pressure, and the exhaust valve 33 is opened. The water in the part 11 can be drained out of the waterproof case 10 through the internal exhaust pipe part 31 to the external exhaust pipe part 32.
