The power module 27 is electrically connected to the display module 21, the processor 22, and the Bluetooth module 25, respectively, to provide power. The housing 1 is also provided with an on / off button 13 on the panel 11. This on / off button 13 is electrically connected to the power module 27 and is used to turn the measuring instrument on and off.

The power module 27 includes a USB external power interface, an SWD interface, a debug serial port, a 5V overcurrent protection circuit, and a low-dropout linear regulator for providing a DC power supply VCC. The display module 21 and host computer interface module 26 are conventional modules and will not be described in detail here.

[0022] See Figure 3 and Figure 4The Bluetooth module 25 includes a voltage regulator chip U1 and a Bluetooth chip U2. The voltage regulator chip U1 uses 6206-3.3, and the Bluetooth chip U2 uses BC417. The voltage regulator chip U1 is used to stabilize the DC power supply VCC of the power module 27 and output a 3.3V DC power supply to power the Bluetooth chip U2. Pin 1 of the Bluetooth chip U2 is connected to the cathode of the voltage regulator diode D1, and the anode of the voltage regulator diode D1 is connected to one end of the resistor R1. Pin 2 of the Bluetooth chip U2 is connected to one end of the resistor R2 and the anode of the voltage regulator diode D2.

[0023] Furthermore, the blood oxygen concentration sensor uses the MAX30102 module. The MAX30102 module can be divided into two parts: one is the analog signal acquisition circuit, which emits light of specific wavelengths through RED and IR lamps, collects the light reflected by the human body, converts the optical signal into an electrical signal through a PD tube, and finally converts it into a digital signal through an 18-bit ADC converter; the second part is the digital processing circuit, which filters the raw data converted by the ADC and places it in a buffer. The processor 22 reads and writes the chip's internal registers through the IIC interface to read the corresponding data.

[0024] The Bluetooth module 25 is connected to the host computer through the host computer interface module 26. The host computer searches for surrounding Bluetooth devices, finds Bluetooth devices, obtains Bluetooth unique identifiers based on the Bluetooth names, and performs Bluetooth connection pairing. This measuring instrument uses a baud rate of 115200 to send and receive data. After configuration, it can receive heart rate and blood oxygen saturation data information transmitted by the lower computer. After a successful connection, the host computer uses the data display thread to display the dynamic waveform of the heart rate and blood oxygen saturation data and the real-time data detection area based on the human heart rate and blood oxygen data measured by the lower computer sensor through Bluetooth interaction. The real-time data detection area displays the specific data of blood oxygen saturation and heart rate, thereby allowing remote viewing of blood oxygen concentration and heart rate, and realizing remote visual management.
