基于微压传感技术的智能充气式止血装置的研制OA

Objective To develop an intelligent compression hemostatic device based on micro-pressure sensing technology for limb bleeding and compare its performance with that of manual inflatable tourniquets.Methods An intelligent inflatable compression hemostatic device was designed using micro-pressure sensors,an automatic pressure inflatable pump,and a pressure fixation belt.The device's inflation performance,material safety,and air tightness were tested through physical property experiments,while its hemostatic efficacy was evaluated using a simulated human limb model and compared with that of manual inflatable tourniquets.Results Compared with the manual inflatable tourniquet,the intelligent inflatable hemostatic device demonstrated significantly shorter inflation time(P<0.05)and better air tightness(P<0.05).In simulation experiments,the hemostasis time for both small artery bleeding and venous bleeding was significantly shorter with the intelligent inflatable hemostatic device than with the manual inflatable tourniquet(P<0.05).Conclusion The intelligent compression hemostatic device outperforms manual inflatable tourniquets in terms of inflation performance,air tightness,and hemostatic efficacy.It enables precise,dynamic,and adaptive pressure management,providing a safer and more effective intelligent solution for combat trauma first aid.
