The watch type sphygmomanometer is an electronic sphygmomanometer that is equivalent to an ordinary watch in size and can be worn continuously for a long time like a watch.
At present, our company has completed the plan design of watch type sphygmomanometer, and the plan features are as follows
1. Small size, low power consumption, and truly wearable medical devices
2. Using oscillographic method, the measurement method is step-up measurement, with short measurement time and accurate blood pressure measurement.
3. Equipped with step counting function and alarm clock function.
4. Low power Bluetooth transmission function, which uploads measurement data to the cloud through a mobile app. Ability to remotely stop discriminating measurement results
5. Easy to operate
6. Using a micro booster pump and a specially customized wrist strap
Meter type wearable sphygmomanometer PCBA measurement mode:
Oscillographic method, 【 boost 】 measurement; Using a V-square 0.8mm DC ultra-thin micro air pump for pressurization, a V-square 0.8mm DC micro rapid exhaust valve for venting, and a V-square 0.8mm pump/valve for integrated pressurization and venting; Semiconductor resistive sensors for pressure detection.
