The electronic sphygmomanometer scheme is an electronic device used to detect human blood pressure. At present, our company has completed the formulation of the arm type blood pressure plan. The device is small in size, low in power consumption, and has realized a real wearable medical device. Its principle adopts oscillographic method, and the detection method is pressure boosting detection, which has a short detection time and accurate blood pressure measurement.

Detection method of electronic sphygmomanometer scheme: oscillography, pressure rise detection/4V DC micro air pump pressurization, 6/4V DC quick exhaust valve exhaust; Semiconductor resistance sensors achieve pressure detection.
