PCBA scheme of arm sphygmomanometerIt is used for electronic sphygmomanometer. The electronic sphygmomanometer is equivalent to an ordinary watch in size and can be worn for a long time like a watch. At present, our company has completed the design of arm sphygmomanometer, which is a real wearable medical device with small size and low power consumption. The principle is oscillographic method, and the measurement method is pressure boosting measurement, which has a short measurement time and accurate blood pressure measurement.
Measurement mode of arm sphygmomanometer PCBA scheme: oscillographic method, pressure rise measurement; 6/4V DC micro air pump pressurization, 6/4V DC fast exhaust valve deflation; Semiconductor resistance sensors perform pressure detection.
Operating range of power supply voltage:
The working range of 6VDC/4 1.5V batteries/5VDC or 5VUSB voltage is 4.4VDC -6.0VDC
The voltage range of 5V DC, 5V USB, or 3.7V lithium batteries is 3.6VDC to 5.0VDC
Measurement range and accuracy: Pressure range: 0~299mmHg (0~39.9kPa), accuracy: 3 mmHg (0.4 kPa);
Pulse rate: 40-200 beats/minute, with an accuracy of 5%.
Sleep power consumption requirement: Under rated working voltage, the shutdown current is 30uA.
Keys: 1-5 light or touch keys can be selected.
Voice function: It can achieve multiple languages such as Chinese and English. With volume control and alarm function
Memory function: It can achieve up to 2 * 240 groups.
Display method: Color TFT, LED screen, LED digital screen, LCD code breaking screen can be customized.
Communication method: Bluetooth communication and UART serial port can be customized.
