Development of PCBA control board for electronic sphygmomanometer scheme

文章來(lái)源:鑫志科技 / 作者:鑫志科技 / 發(fā)表時(shí)間:2022-04-27

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.

Power supply and voltage operating range:

6VDC/4 1.5V batteries/5VDC or 5VUSB voltage operating range 4.4VDC-6.0VDC.

The operating range of 5VDC or 5VUSB or 3.7V lithium battery voltage is 3.6VDC-5.0VDC.

Measurement range and accuracy: Pressure range: 0~to 299mmHg (0~to 39.9kPa), accuracy: ± 3mm Hg (± 0.4 kPa);

Pulse count: 40-200 beats/minute, with an accuracy of ± 5%.

Sleep power consumption requirement: Under rated working voltage, the shutdown current is ≤ 30ua.

Press to select 1-5 touch or touch buttons.

Display method: Color screen TFT, LED screen, LED digital screen, LCD break code screen can be customized.

Voice function: All countries' voices, such as Chinese and English, can be implemented. With volume control and alarm function.

Memory function * Memory function below 240 groups.

Communication method: Bluetooth communication, UART serial port customizable.
