Abstract
The utility model discloses a sphygmomanometer belonging to medical instrument field. An end cover is arranged upon the mercury tube with scales of the sphygmomanometer, a small hole is opened upon the end cover, and a filter membrane is disposed between the mercury tube with scales and the end cover. The pore of the filter membrane can be permeated by air but not the mercury, therefore avoiding mercury leakage due to sphygmomanometer inversion in the process of use and transportation. The utility model is characterized in simple structure, low cost, convenient and reliable use, etc., thus the device is an ideal sphygmomanometer of mercury-column type without leakage.
Description
This utility model relates to a kind of sphygomanometer, the leak free sphygomanometer of hydrargyrum in particularly a kind of use and the transportation.
Sphygomanometer is that people are used for measuring indirectly a kind of medical apparatus and instruments of arteriotony, commonly used is the hydrargyrum pillar, include scale be filled with water glass tubing and the rubber tube, rubber pocket cuff, the ball etc. of inflating of silver, there is the be filled with water top of glass tubing of silver of scale to be provided with end cap, the top of end cap has the less aperture in an aperture, so that allow air pass through, assurance have scale be filled with water silver glass tubing in pressure consistent with atmospheric pressure, because hydrargyrum density is bigger, in transportation or use, when the sphygomanometer lodging occurring, hydrargyrum often occurs and from aperture, leak out.Sphygomanometer after the improvement is mostly made an issue of in measurement and hydrargyrum control, Zhai Li newly-designed " novel mercurial sphygmomanometer " (number of patent application: 93236866.2), " the desk-top mercurial sphygmomanometer of electronics " (number of patent application: 94241860.3) of Zhou Guofang, Tao Yijun design, 89101326.1) and " with the device that opens and closes mercurial sphygmomanometer " (number of patent application: 89103546.X), still can not solve in use and the transportation problems such as hydrargyrum leakage " mercurial sphygmomanometer " of Amada Co., Ltd. mountain longevity invention (number of patent application:.
The purpose of this utility model provides a kind of nothing and leaks mercury column sphygmomanometer.
This utility model is to realize like this, blood pressure contain in respect of scale mercury tube above be provided with end cap, the top of end cap has aperture, has scale to contain between mercury tube and the end cap and is provided with filter membrane, the hole of filter membrane can stop seeing through of hydrargyrum by air, thereby plays leak free effect.
Below in conjunction with accompanying drawing this utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
1 is air-vent in the accompanying drawing, the 2nd, and end cap, 3 end caps are contained connecting between the mercury tube with scale is arranged, and the 4th, filter membrane, the 5th, there is scale to contain mercury tube.
Contain mercury tube (5) at blood pressure in respect of scale and be provided with end cap (2), above end cap, open face air-vent (1), have scale to contain between mercury tube (5) and the end cap (2) and be provided with filter membrane (4), the hole of filter membrane (4) can stop seeing through of hydrargyrum by air, thereby plays leak free effect.This utility model is that ideal nothing is leaked one of sphygomanometer.
Claims (2)
1. a sphygomanometer is made up of hydrargyrum bin, mercoid switch, the glass tubing, panel etc. that hydrargyrum are housed by scale, it is characterized in that blood pressure contain in respect of scale mercury tube above be provided with end cap, the top of end cap has aperture, has scale to contain between mercury tube and the end cap and is provided with filter membrane.
2. sphygomanometer according to claim 1 is characterized in that the hole of filter membrane can stop seeing through of hydrargyrum by air.
