Mkb0803 continuous heart rate and blood pressure monitoring scheme

方案描述：

Mkb0803 heart rate and blood pressure module realizes: high integration and high stability, automatic falling off detection, no data output, automatic skin color recognition, hrv-pnn50 (optional).

The heart rate and blood pressure monitoring scheme is mainly composed of one yk1801 pulse sensor chip, one analog front-end mn8802 pulse chip and one sfb9712 algorithm chip. According to the circuit diagram provided by us, customers can make PCB with an area of less than 18mm * 12mm, output blood pressure and heart rate Serial uart signals, which is easy to extract and use.

The pulse sensor chip uses photoelectric volume pulse oscillography (PPG) to sense and extract the pulse information of human body, and outputs serial port signals such as blood pressure and heart rate through analog front-end chip mn8802 and algorithm chip sfb9712.

The heart rate and blood pressure monitoring scheme can realize the following functions: heart rate and blood pressure acquisition and calculation, pulse wave and ECG waveform output (optional), human wearing state identification, human body surface temperature monitoring (optional), hrv-pnn50 (optional), respiratory rate (customized), blood pressure tracking and monitoring and other physical health indicators.

Principle of blood pressure scheme: it mainly monitors the change trend of users' blood pressure through PPG feature cognition, tracking and comparison.

Output mode: serial port or I2C.

Output contents: heart rate, blood pressure, pulse wave and ECG waveform (optional), wearing status identification, temperature data (optional), hrv-pnn50 (optional), respiratory rate (customized), etc.

The user implementation method is simple: the main work is only hardware design and structure arrangement, which reduces the requirements for the CPU of the whole machine and software debugging.

The biggest features of the blood pressure test module are: high integration and high stability, automatic wear recognition and disengagement, no output; MCU algorithm is used, heart rate and blood pressure algorithm is implanted, and UART signal of serial port is directly output, which simplifies the workload of customers, is simple and reliable, and is convenient for customers to use.
