Embodiment Construction

[0017] The electronic sphygmomanometer provided by the present invention includes an inflation and deflation device, a pressure device, a measuring device, a control device and a display device, etc., as shown in Fig. 1 and Fig. As a pressure device, the channel 2 directly acts on the limb of the person to be measured and blocks the pulse of the limb by gas pressure. The air pump 11, solenoid valve 13 and mechanical valve 15 as the inflation and deflation device are respectively communicated with the gas passage 2, for example, the air pump 11, the solenoid valve 13 and the mechanical valve 15 can be connected with the cuff through several air pipes respectively, To inflate and deflate the airbag. The measuring device includes a pressure sensor 31, a signal amplification circuit 32 connected to the pressure sensor 31 and an analog / digital (A / D) signal conversion circuit 33 in turn, and a trachea is connected to the pressure sensor 31 from the air bag, so that The pressure sen...

Abstract

The invention relates to an electric blood pressure meter, which comprises automatic aerator, pressure device, measurer, controller and display. Wherein, it uses aerator to aerate the pressure device, uses sensor to sense the pressure of air bubble to obtain the pressure valve, and display the valve on analogue mercury ruler; the ruler is divided into several sections, based on pressure values to display the section at said pressure value, and indicate relative ruler scale. Therefore, the electric blood pressure meter can avoid display whole mercury ruler, but display segmented, to reduce the cost and avoid hand-operated aerating, to simplify the operation, and uses the automatic discharge valve to uniformly discharge air to improve the accuracy.

Description

【Technical field】 [0001] The invention relates to an electronic sphygmomanometer, in particular to an analog mercury column type electronic sphygmomanometer which uses a liquid crystal display device to simulate a mercury column to display the changing state of blood pressure values ​​for a measurer to use a stethoscope to accurately read the blood pressure values. 【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 example, the column height exceeds the systolic blood pressure by 20-30mmHg), the airbag pressure blocks the blood flow of the upper arm artery, and the pulse so...
