Electronic sphygmomanometer

Abstract

The invention discloses an electronic sphygmomanometer, which comprises an automatic inflation and deflation device, a pressure device, a measuring device, a control device, and first and second display devices, and uses the automatic inflation and deflation device to inflate and deflate the pressure device , use the sensor to sense the air bag pressure signal and obtain the pressure value through calculation and processing, and display it in the analog mercury column scale displayed by the first display device, wherein the analog mercury column scale is divided into several scale segments, according to the pressure value At least the analog mercury column scale section where the pressure value is located is displayed, and the analog mercury column is indicated on the scale scale corresponding to the pressure value, so that the doctor can listen to the Korotkoff sound with a stethoscope to obtain the blood pressure value. It can also directly display the measurement results automatically calculated by using the principle of the oscillometric method in digital form on the second display device. In this way, the electronic sphygmomanometer does not need to display a mercury column scale in the form of a complete and coherent long column, but displays it in segments, which can solve the problems of excessive size and high cost of the liquid crystal display screen, and does not require measuring personnel Manually inflate and deflate, and automatically get the measurement results, which can reduce the human operation during the measurement process and improve the accuracy of the measurement.

Description

【Technical field】 [0001] The invention relates to an electronic sphygmomanometer, in particular to an electronic sphygmomanometer which uses a liquid crystal display device to simulate the mercury column to display the change state of the blood pressure value, which can be used by the measurer to choose to use a stethoscope to accurately read the blood pressure value and choose to automatically calculate the blood pressure result and directly display the number. The analog mercury column electronic sphygmomanometer. 【Background technique】 [0002] Traditionally, the desktop mercury sphygmomanometer is the most commonly used for human blood pressure measurement. The method of use is to wrap the air bag around the upper arm of the person being measured, place the chest piece of the stethoscope on the brachial artery of the elbow, and pass the rubber ball Inflate the airbag to make the mercury column rise. When the mercury column height exceeds the systolic pressure (for exampl...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problems of inaccurate measurement values, oversized size, and high cost and price in the aforementioned existing electronic digital blood pressure measuring devices, and to provide a device that can be automatically inflated and deflated and can be selected according to the traditional blood pressure measurement habits. With the measurement mode of the stethoscope reading, you can also choose the measurement mode of automatically calculating the blood pressure result and directly displaying the blood pressure value, which can obtain accurate blood pressure measurement values, and the analog mercury column electronic blood pressure with a small appearance and more competitive cost and price count
