Program introduction:
The wrist sphygmomanometer solution is a medical device that uses modern electronic technology and the principle of indirect blood pressure measurement to measure blood pressure. Most of them use the principle of oscillometric method to measure blood pressure. The household portable sphygmomanometer is mainly composed of MCU, display panel, air pressure sensor, cuff, air pump, battery, etc. Its working principle is to calculate the systolic pressure, diastolic pressure, mean arterial pressure. This kind of product is used in a wide range, mainly because there are elderly people at home for daily use. The sphygmomanometer can measure the average value of human blood pressure, and use the blood pressure data as a judgment of the user's health problems. When the blood pressure is detected to be low, you can advance Prevention and treatment of minor diseases to avoid the risk of serious diseases.
Wrist blood pressure monitor PCBA program working process:
The whole scheme uses SIC32F911RET6 as the control chip for blood pressure measurement and display of the whole machine. The fluctuation of blood pressure in arteries is monitored through the SIC160 pressure sensor with temperature compensation, converted into frequency, and processed by filtering algorithm to calculate systolic pressure, diastolic pressure, and average pressure. Arterial pressure, and drives a 4.3-inch 800*480 resolution LCD panel to display blood pressure and pulse rate, and automatically announces the measurement results by voice.
Wrist Blood Pressure Monitor Solution Features:
1. Accurate data: The filtering algorithm is used to accurately calculate the systolic and diastolic blood pressure values. Display accuracy 1mmHg (0.133Kpa);
2. Intelligent pressurization: built-in 24-bit high-precision digital air pressure sensor, precisely controls the inflation and deflation of the cuff, and effectively eliminates measurement artifacts;
3. Voice broadcast: support volume adjustment, and the measurement results can be automatically voice broadcast throughout the process;
4. Large screen: the display is clearer, the algorithm has been tested extensively and is more stable, and stores 100 sets of historical memories;
5. Rich interface elements: Real-time blood pressure value display, high and low pressure warning and brightness adjustment can be realized;
6. Rechargeable: Built-in rechargeable lithium battery, with Mini USB charging interface, easy to charge, no need to replace the battery.
7. Automatic shutdown: automatic shutdown without operation in 1 minute
8. Simple operation: one-key measurement, easy to use, good stability, environmentally friendly materials, safe to use
9. Blood pressure measurement range: 0~ to 299mmHg (0~ to 39.9kPa), pulse measurement range (40~200 beats/minute)
10. Measurement accuracy: pressure accuracy ±3mmHg (±0.4kPa) pulse accuracy ±5%
The currently designed wrist blood pressure monitor solution can provide a main control chip (IC) with PCBA production materials, or provide a module (PCBA) with complete operation instructions and technical solutions to cooperate with factory production. During the development process, the design should be developed according to the needs, and the hardware and software can be modified during the period. Finally, the samples will be tested and sent. If there is no problem, mass production and supply will be made.
