Medical non-hydrargyrum sphygmomanometer

Abstract

A medical non-mercury sphygmomanometer comprises a cuff, an air filling-discharging device, a pressure sensor, a pulse hearing device, an input unit, a display unit and a SCM control unit; wherein, the display unit contains an analog mercury column display screen and a blood pressure display screen; the SCM control unit processes and then converts the collected blood pressure amplitude data to display on the analog mercury column display screen and the blood pressure display screen; the SCM control unit also comprises a judgment module and a data amplification module; wherein, the judgment module generates the beating point and the recovery point of each pulse beating period; the data amplification module is used for amplifying the collected blood pressure amplitude data of each pulse beating period to increase the sensing display amplitude of the blood pressure amplitude data of each pulse beating period being output to the analog mercury column and the blood pressure display screen. So the medical non-mercury sphygmomanometer of the invention has high measurement accuracy, and has the advantages of direct viewing and convenience.

Description

technical field [0001] The invention relates to a medical mercury-free sphygmomanometer, in particular to a display method of the measured value of the medical mercury-free sphygmomanometer. Background technique [0002] With the development of society and the improvement of people's living standards, people need to know more about their physical conditions; and at the same time, due to the pollution caused by the development of industrial society to people's living environment, people also hope to have a This tool can give them a general understanding of their own physical condition, and according to scientific research, the level of blood pressure is a manifestation of good or bad physical condition. Thereby people are more concerned about each index of blood pressure in daily life, and from the blood pressure measuring instrument provided by prior art, mainly contain mercury sphygmomanometer and electronic sphygmomanometer. [0003] Mercury sphygmomanometers have the adv...

AI Technical Summary

Problems solved by technology

[0007] 1. The existing electronic sphygmomanometer either uses a liquid crystal strip to simulate a mercury column to read the blood pressure value, or directly converts the pressure value into a digital display through the liquid crystal block, because the analog mercury column has a small beating range and a relatively short time when the blood pressure is generated. Short, it is difficult for users to observe and capture this data;

[0008] 2. When the electronic sphygmomanometer in the prior art measures the blood pressure value, the sampling time interval and sampling accuracy of the analog / digital conversion of the blood pressure value are not enough
