Description

  The present invention relates to a pressure stable release device of a kind of electronic sphygmomanometer, and more specifically, using a plug member made of a kind of porous gas-permeable material, using a fine and uniform vent hole of the plug member, The present invention relates to a pressure stable release device for an electronic sphygmomanometer that can more accurately realize pulse signal detection of a human body by stably releasing an air flow rate at a low flow rate.

  As shown in FIG. 1, a normal electronic sphygmomanometer has all electronic components mounted on one printed circuit board 110 and wraps the printed circuit board 110 by a box 100. Further, a liquid crystal display device (LCD) 120 is mounted on the printed circuit board 110 so as to be exposed on the surface of the box 100, and the blood pressure measurement result is displayed. Further, a connecting pipe 130 of a porous gas communication passage is provided on the box body 100, the connecting pipe 130 is connected to a joint 131, and the joint 131 is connected to an air bag (not shown). The air bag is wrapped around the upper hip or arm. This communication pipe 130 further communicates with a low flow gas relief valve 132, a pulse sensor 133, a pump 134 and a high flow gas relief valve 135. Of these, the pulse sensor 133 is mounted on the printed circuit board 110 to detect blood pressure pulsation.

  As shown in FIG. 2, a storage space 1321 corresponding to one opening of the pair of connecting pipes 130 is provided in the low flow gas relief valve 132, and a silicon (rubber) pipe 1322 having a hollow interior is provided in the storage space 1321. . One end of the silicon (rubber) tube 1322 is hermetically sealed, and an opening is provided at the opposite end. Further, a vertical tear 1323 is provided on the surface of the silicon (rubber) tube 1322, and the vertical tear 1323 allows the gas inside the storage space 1321 and the silicon (rubber) tube 1322 to flow. Further, the silicon (rubber) tube 1322 is provided with a screw tube 1324 at the opening end, and a ventilation passage 13241 is provided inside the screw tube 1324, and the ventilation passage 13241 communicates with the opening end of the silicon (rubber) tube 1322. The threaded tube 1324 can be screwed into the nut 1325. Furthermore, the nut 1325 is fitted into the storage space 1321. Thus, when operated, the pump 134 feeds pressurized gas into the air bladder via the connecting pipe 130 and rotates the nut 1325 by the threaded pipe 1324 after the atmospheric pressure reaches the set maximum value.

  The silicon (rubber) tube 1322 that was originally compressed by the air passage 1326 moves up / down, and the gas in the air bag passes through the communication tube 130, from the air passage 1326, and from the slit 1323 of the silicon (rubber) tube 1322 to the silicon ( Enter the rubber) tube 1322. The gas is caused to flow out by the through air passage 13241 inside the screw tube 1324. At this time, the high flow rate gas relief valve 135 is closed, and the pulse sensor 133 detects the high / low blood pressure pulse by gradually releasing the gas. After transmitting and processing the detected high / low blood pressure pulse data to the printed circuit board 110 and transmitting the measurement result to the liquid crystal display device 120, the high flow gas relief valve 135 is opened and the remaining gas is a high flow gas relief. Discharge faster than the valve.

  However, since most of the low flow rate gas relief valve 132 is made of silicon (rubber) material, it deteriorates after use for a certain period of time and causes deformation and embrittlement due to elastic fatigue. Therefore, the flow rate of gas entering the storage space 1321 becomes unstable, and the measurement result cannot be accurately maintained.

  Further, the flow rate of the release gas is determined by the section “a” in FIG. 2 by the combination of the screw tube 1324 and the nut 1325. Further, since the thread on the threaded tube 1324 and the nut 1325 is processed by a machine tool, there is a limit to the approach of the thread and cannot be adjusted to a fine interval. Since the vertical tear 1323 on the silicon (rubber) tube 1322 is also machined, the gas flow rate cannot be released in a very small amount, the gas flow rate to be released is also unstable, and the measurement pressure can be reduced. Can not. As an example, the gas flow rate introduced into the storage space 1321 is 2-5 mmhg / sec, and the pressure per second of the pulse sensor 133 cannot be lowered or the measurement interval cannot be shortened, so accurate measurement cannot be performed.

  The present invention has been made to remedy the above-described drawbacks, and an object of the present invention is to provide a stable pressure release device for an electronic sphygmomanometer that can measure stably and accurately.

The first device of the present application is a pressure stable release device for an electronic sphygmomanometer, in which a communication pipe for a porous gas communication passage is provided on the apparatus, and an air bag, a pump, and a pulse sensor are connected to one end of the communication pipe. A plug member is provided at one end, and this plug member is made of a material for the porous gas communication passage. When used, the plug member is pressurized with a pump and pumped to the communication tube, and filled with an air bag. The fine and uniform air holes inside the air bag allow the gas in the air bag to be finely, uniformly and stably discharged through the air holes, and accurately measure the amount of gas released by the pulse sensor. This is a pressure stable release device for electronic blood pressure monitors.
