The photoelectric probe 110 is used to alternately emit infrared light and red light to the skin flap to be detected, and convert the collected infrared light and red light through the skin flap to be detected into electrical signals, and send the above electrical signals to the processing device 130;

The above-mentioned Doppler probe 120 is used to transmit ultrasonic waves to the skin flap to be detected, and receive echo signals reflected back from the skin flap to be detected, and send the above-mentioned echo signals to the processor 130;

The processor 130 is configured to receive the electrical signal sent by the photoelectric probe, process the electrical signal, obtain the blood oxygen saturation of the skin flap to be detected, and receive the echo signal sent by the Doppler probe 120, and process the above-mentioned electrical signal. The echo signal is processed to obtain the blood flow velocity of the skin flap to be detected, and the blood oxygen saturation and blood flow velocity are sent to the display 140;

The display 140 is configured to receive the blood oxygen saturation and blood flow velocity sent by the processor 130 and display the blood oxygen saturation and blood flow velocity.

The above-mentioned display 140 may be a light-emitting diode (Light-Emitting Diode, LED) display, or a liquid crystal display (Liquid Crystal Display, LCD).

In an embodiment of the present invention, as shown in FIG. 2 , the above-mentioned photoelectric probe 110 includes a photoelectric transmitter 111 and a photoelectric receiver 112, and the above-mentioned photoelectric receiver 112 is connected to a processor 130;

The photoelectric transmitter 111 is used to alternately emit infrared light and red light to the skin flap to be detected;
