Description

The present invention relates to a pressure release stabilization device for a large air bag used in combination with a kind of blood pressure monitor, and in particular, by providing an air plug of a kind of porous air-permeable member in an air bag surrounding a human arm, the manufacturer is the same. The air flow of the sphygmomanometer by the air release valve of the size is controlled, and the air flow of the large air bag can be increased by the fine and uniform air holes provided in the air plug of the large air bag, The present invention relates to a pressure release stabilizer for a sphygmomanometer bladder that can stably release air by means of a plug and an air release valve of the sphygmomanometer.

As shown in FIG. 1A, the prior art sphygmomanometer is provided with a connecting pipe 100, connected to the pressurizing pump 110 at one end of the connecting pipe 100, and connected to the air bag 200 surrounding the arm or wrist at the other end. To do. Furthermore, the air bag 200 has a standard size and a large size according to the user's arm size. Among them, the standard size (arm size: 9 to 13 inches) is suitable for an oriental human body or a general Western arm, and the large size (arm sizes of 13 to 17 inches) is suitable for the arm of a user having a slightly thick body shape.

As shown in FIGS. 1A and 1B, the connecting pipe 100 is connected to a pulse sensor 120, an electromagnetic valve 130 and an air release valve 131. Among them, the pulse sensor 120 is provided on the electric circuit board 140, detects blood pressure pulsation at the time of measurement, and measures high / low blood pressure values. The electric circuit board 140 is connected to the liquid crystal display panel 150 by an electric circuit. The electromagnetic valve 130 can quickly release the air in the air bag 200, and the air release valve 131 releases the air in the air bag with a low air flow rate when measuring the blood pressure.
However, the measurement of the high / low blood pressure value by the pulse sensor 120 pressurizes the air bag 200 to a preset maximum pressure value and then releases the air in the air bag 200 at a constant time with a low air flow rate. Therefore, since the size of the air bag 200, the air flow rate discharged from the air release valve 131, and the discharge stability affect the measurement accuracy, the size of the air discharge port of the air release valve 131 differs depending on the size of the air bag 200. As an example, since the volume of a large-sized air bag is large, the air discharge period during measurement is also long. Therefore, it is necessary to largely adjust the air discharge port 132 to increase the air flow rate. For this reason, the size of the air discharge port 132 of the sphygmomanometer must be adjusted according to the size of the air bag 200 to be connected.
However, the sphygmomanometer is shipped from the factory as a unified standard, and a standard size air bag is used as a standard for adjustment. Therefore, when the large-sized air bag 200 is connected to the sphygmomanometer, the accuracy of the measured value is inferior.

      The present invention has started research and analysis of the improvement measures for the problem of controlling the air flow rate by adjusting the air discharge port of the air release valve in the prior art sphygmomanometer according to the size of the air bag. As a result of repeating, the pressure release stabilizing device of the sphygmomanometer air bag of the present invention was devised.

The opening of the air outlet is adjusted and set according to the air discharge flow rate suitable for the standard size air bag.
Due to this structure, when the present invention is used for a large size air bag for a large arm size, the air of the pressurizing device is pressurized by a connecting pipe to pressurize the air bag to a preset pressure and measure the blood pressure. In addition to being able to release air from the air discharge port provided in the air release valve, the air flow released to the outside is increased by the fine and evenly distributed vent holes provided in the air plug of the large size air bag .

That is, the first device of the present application is provided with a connecting pipe that is connected to the sphygmomanometer, a pressurizing device and an air release valve are provided in each of the connection pipes, and the air discharge flow rate at the air discharge port of the air release valve is air of standard size. Set according to the bag, connect to a large air bag surrounding the arm or wrist at the other end of the connection path, provide an air plug made of porous air permeable member to the large air bag, and connect the air pressurized by the pressurizing device After the large air bag reaches the preset maximum pressure value after being pumped to the pipe, the air outlet of the air release valve and the air plug provided in the large air bag are fine and uniform vent holes. A pressure release stabilizing device for a sphygmomanometer air bag, characterized in that the air in the air bag is fine and stably passes through the vent hole and is discharged to the outside.
A second device of the present application provides the pressure release stabilizing device for a sphygmomanometer air bag according to the first device, wherein the air plug is made of fine ceramics.
A third device of the present application provides the pressure release stabilizing device for a sphygmomanometer air bag according to the first device, wherein the pressurizing device is a pump.
A fourth device of the present application provides the pressure release stabilizing device for a sphygmomanometer air bag according to the first device, wherein the pressure device is a manual pressure ball.
A fifth device of the present application provides a pressure release stabilizing device for a sphygmomanometer air bag according to the first device, wherein the size of the large air bag is 13 to 17 inches.

Therefore, the blood pressure pulse signal can be detected more accurately from the pulse sensor when the air discharge amount is stable. The present invention eliminates the need to individually adjust the opening of the air outlet of the sphygmomanometer, and can be applied to both standard and large air bags. Can be reduced.
