Embodiment Construction

[0018] The electronic sphygmomanometer provided by the present invention includes an inflation and deflation device, a pressure device, a measurement device, a control device, and a first and second display device. Please refer to FIG. 1 and FIG. 2 . The inner gas channel 2 acts as a pressure device, directly acting on the limb of the measured person and blocking the pulse of the limb by means of gas pressure. The inflator 11, the solenoid valve 13 and the mechanical valve 15 as the inflating and deflating devices are respectively communicated with the gas channel 2. For example, the inflator 11, the solenoid valve 13 and the mechanical valve 15 can be respectively communicated with the cuff through a number of trachea, To inflate and deflate the air bag. The measuring device includes a pressure sensor 31, a signal amplification circuit 32 and an analog / digital (A / D) signal conversion circuit 33 connected to the pressure sensor 31 in turn. Changes in the gas pressure in the a...

Abstract

The invention relates to an electric blood pressure meter, which comprises automatic aerator, pressure device, measurer, controller, first and second displays. wherein, the aerator can aerates the pressure device; the sensor senses the pressure signal of air bubble to obtain pressure value, to display said value on the analogue mercury ruler of first display; said ruler is divided into several segments, to display the section at said pressure value at least, and indicate the analogue mercury post to relative ruler scale, to be detected by doctor to obtain blood pressure value; and the invention can use oscillography to automatically calculate out the measure result to display it on second display as numbers; 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 present invention relates to an electronic sphygmomanometer, in particular to an electronic sphygmomanometer that uses a liquid crystal display device to simulate a mercury column to display the changing state of a blood pressure value, which can be used by a 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 digital value. The analog mercury column electronic sphygmomanometer. 【Background technique】 [0002] Traditionally, the desktop mercury sphygmomanometer is the most commonly used in the measurement of human blood pressure. Inflate the air bag to make the mercury column rise. When the height of the mercury column exceeds the systolic blood pressure (for example, the column height exceeds the systolic blood pressure by 20-30 mmHg), the air bag pressure blocks the blood flow of the upper arm artery, and the pulse sound disa...
