Development of an intelligent inflatable hemostatic device based on micro-pressure sensing technology

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.

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.

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).

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.
