Electronic sphygmomanometer based on single-chip microcomputer

Abstract

The invention discloses an electronic sphygmomanometer based on a single-chip microcomputer. The electronic sphygmomanometer based on the single-chip microcomputer comprises a blood pressure signal detection module, the single-chip microcomputer, an inflation and deflation control circuit and a power module, wherein the blood pressure signal detection module is connected with the input end of the single-chip microcomputer, the input end of the single-chip microcomputer is further connected with an undervoltage detection circuit module which is used for resetting the single-chip microcomputer when the voltage of a power source falls to the lowest voltage needed by the single-chip microcomputer, the undervoltage detection circuit module is connected with the inflation and deflation control circuit, the input end of the single-chip microcomputer is further connected with a plurality of keys, the output end of the single-chip microcomputer is connected with the inflation and deflation control circuit and further connected with a display screen and a voice prompting circuit module, the display screen is used for displaying information of systolic pressure, diastolic pressure and heart rate, and the voice prompting circuit module is used for achieving automatic voice promoting of a blood pressure measurement value. The electronic sphygmomanometer based on the single-chip microcomputer is reasonable in structural design, small, low in power consumption, high in speed, easy to operate and convenient to popularize and use, and facilitates function extension.

Description

technical field [0001] The invention relates to an electronic sphygmomanometer, in particular to an electronic sphygmomanometer based on a single-chip microcomputer. Background technique [0002] With the continuous improvement of people's living standards and the increase in the proportion of aging people, people's self-care awareness is gradually enhanced, and the trend of home-based medical testing equipment is becoming more and more obvious. Among them, the household electronic sphygmomanometer is one of the typical home medical testing equipment. In the past, barometric sphygmomanometers were used to measure blood pressure. This kind of sphygmomanometer is not easy for ordinary people except doctors, and it is inconvenient to measure for yourself. With the rapid development of electronic technology, electronic sphygmomanometers have gradually appeared. Early electronic sphygmomanometers had the function of measuring blood pressure in addition to the functions of electr...

AI Technical Summary

Problems solved by technology

The early electronic sphygmomanometer had the function of measuring blood pressure in addition to the function of the electronic watch. The operation was cumbersome and it was not easy to operate alone.
