【Abstract】 Objective To develop a portable tissue blood oxygen detector for clinical real-time and dynamic detection of tissue blood oxygen values after amputated finger/limb replantation and skin flap transplantation, so as to help medical staff early assess the tissue blood supply of replanted tissues. Methods Based on near-infrared spectroscopy, tissue blood oxygen detection was performed by using the principle that oxygenated hemoglobin and deoxyhemoglobin in human blood have different absorption of near-infrared light, using wireless Bluetooth technology to realize terminal data transmission, and long-term big data management and artificial intelligence algorithm to intelligently evaluate the blood oxygen level of the replanted tissue. Results The measurement range of blood oxygen parameters of the replanted tissue of the equipment was 20% to 100%, the error value was ±2%, and the effective wireless transmission distance was >3 m. The big data management based on artificial intelligence algorithm could realize the calibration and evaluation of tissue blood oxygen level. Conclusion The wireless portable tissue blood oxygen detector is small in size, light in weight, and accurate in measurement data. It can help medical staff to understand the recovery of the replanted tissue in real time, which is conducive to grasp the best opportunity for treatment.更多还原
