Ratchet Quick-Release Tourniquet The ratchet mechanism simplifies the process of applying pressure and securing the windlass tourniquet. Nylon straps with buckles enable rapid initial placement. Once tightened by rotating the ratchet, it locks automatically with no additional steps needed to secure the windlass. This reliable windlass tourniquet saves valuable rescue time through simplified operation. This upgraded tourniquet uses a ratchet for automatic locking instead of manually secured windlasses, simplifying operation to reduce emergency response time and enabling quick one-handed use. Widened nylon strap provides a larger pressure surface during compression, distributes pressure evenly, and enables efficient hemostasis. The buckle design allows for quick fastening of the tourniquet and enables rapid release of the strap when undoing it. The compact and lightweight design, constructed from nylon and reinforced engineering plastics, ensures portability with durable quality that delivers reliable performance in various harsh environments. Warning: When applying pressure to stop bleeding, remember to record the time of tourniquet application. Seek medical treatment as soon as possible after hemostasis. The application duration should not exceed 2 hours to prevent necrosis caused by prolonged limb ischemia.
