Embodiment 1

[0047] refer to figure 1 As shown, the embodiment of the present invention provides a skin flap blood flow detector, including a photoelectric probe 110, a Doppler probe 120, a processor 130 and a display 140;

[0048] Above-mentioned photoelectric probe 110, Doppler probe 120 and display 140 are all connected with processor 130;

[0049]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;

[0050] 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;

[0051] The processor 130 is configured to receive the electrical signal sent by the phot...

Embodiment 2

[0106] refer to Image 6 As shown, the embodiment of the present invention also provides a blood flow detection system, the blood flow detection system includes a detection terminal 610 and the blood flow detection instrument 620 provided in the above-mentioned embodiment 1;

[0107] The detection terminal 610 is connected to the blood flow detector 620 and receives the blood oxygen saturation and blood flow velocity of the flap to be detected sent by the blood flow detector 620 .

[0108] Specifically, the detection terminal 610 and the blood flow detector 620 are connected through a wireless network, and the wireless network may be a WIFI network, a 3G network, or the like.

[0109] In the embodiment of the present invention, the above-mentioned blood flow detector is equipped with a photoelectric probe, a Doppler probe and a processor, which can measure the blood oxygen saturation and blood flow velocity at the skin flap to be detected, and the detected blood oxygen The sa...

Abstract

The invention provides a blood flow detector and a detection system. The blood flow detector comprises a photoelectric probe, a Doppler probe, a processor and a displayer. The photoelectric probe, the Doppler probe and the displayer are connected with the processor. By detecting the blood oxygen saturation degree, blood flow speed and other objective indexes of the flap, whether or not a pedicle division operation can be conducted is judged. Compared with the prior art, the judgment accuracy is very high. Besides, whether the pedicle division operation is conducted or not is judged according to the two indexes, namely the blood oxygen saturation degree and the blood flow speed, and the judgment accuracy is further improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a blood flow detector and a detection system. Background technique [0002] Flap transfer is a common method for tissue or organ defect and reconstruction in plastic surgery and trauma surgery. For flaps transferred with pedicles, it is necessary to establish a new blood circulation with the recipient tissue before disconnecting the pedicle (the pedicle refers to the part where the flap connects to the donor), otherwise the transferred flap will suffer from necrosis , that is, the operation failed. [0003] In the prior art, medical personnel generally judge whether the flap pedicle surgery can be performed by measuring the temperature of the flap, observing the skin color difference between the flap donor and the recipient area, and combining their own experience. Due to differences in clinical experience, medical staff have different grasps of surgical indications, an...
