AI Technical Summary
Existing tourniquets fail under field conditions due to insufficient power or mechanical malfunctions, leading to interruptions in hemostasis operations and failing to meet the requirements of intelligence, high reliability, and toughness.
Design a tourniquet with automatic fault switching function. It achieves pneumatic compression hemostasis through an inflation component. In the event of power failure or malfunction, it automatically switches to mechanical emergency mode. The emergency component provides driving force to the rotating column to achieve mechanical tightening of the hemostatic airbag. It enters standby working state through a tactile signal prompt device.
It can maintain reliable hemostatic pressure even in the event of power outage or failure, reduce local pressure differences, reduce the risk of infection, reduce secondary damage, and ensure hemostatic effect through fault indication.
