Example Embodiment

[0031] See figure 1 and figure 2 As shown, the electronic sphygmomanometer provided by the present invention includes a rubber ball 1 as an inflator device, an airbag 2 as a pressure device, a measurement and control device 3 and other components, wherein the rubber ball 1 and the airbag 2 are connected through an air intake pipe 12, and An exhaust valve 11 is provided on the intake pipe 12 to control the discharge of gas in the airbag 2. The airbag 2 is provided with a vent tube 21 connected to the inside of the measurement and control device 3 and communicated with a pressure sensor 31 inside the measurement and control device 3, so that the pressure sensor 31 can sense the change of the gas pressure in the airbag. It is easy to understand that the pressure sensor 31 can also be arranged in the airbag 2 and connected to the internal circuit of the measurement and control device 3 through a wire. The measurement and control device 3 is provided with a central processing unit 30,...

Abstract

This invention discloses a kind of electronic sphygmomanometer and its displaying technique: a sensor senses gasbag pressure signal and educe pressure value after operation process, and outputs the value to a displaying unit to display it by means of a simulated quicksilver column scale. Wherein, the scale is divvied into sections according to designed program, and the scale mark is set by pressure comparison and judgment. In this way, pressure values can be displayed by a subsection manner instead of a full and consistent long column shape. So liquid crystalline display screen of the sphygmomanometer can be smaller and cheaper, at the same time, the resolution ratio of this invention is enough to meet high accuracy need of the scale mark.

Description

【Technical field】 [0001] The present invention relates to an electronic sphygmomanometer and its display method, in particular to an electronic sphygmomanometer and its display which uses a liquid crystal display device to simulate the mercury column to display the change state of the blood pressure value, so that the measurer can accurately read the blood pressure value with a stethoscope method. 【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 cuff 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 The ball inflates the cuff to make the mercury column rise. When the mercury column height exceeds the systolic blood pressure (for example, the column height exceeds the systolic blood pressure by 20-30mmHg), the cuff pressure blocks the blood flow of ...
