Hospital Disposables Medical Hemostatic Band Tourniquets

‌Introduction to the Tourniquet

A tourniquet is a medical device designed to temporarily control severe bleeding from an extremity (arm or leg) in emergency situations. It works by applying circumferential pressure around a limb, compressing blood vessels and restricting blood flow to the injured area. Tourniquets are critical tools in first aid, military medicine, and trauma care, particularly when direct pressure or elevation fails to stop life-threatening hemorrhages.

‌Components and Design

Modern tourniquets typically consist of a sturdy strap, a windlass (a rod or stick for tightening), and a securing mechanism. High-quality models, such as the Combat Application Tourniquet (CAT) or the SAM-XT, are made from durable materials to ensure reliability under harsh conditions. Some also include padding to reduce tissue damage during application.

‌Proper Usage‌

1. ‌Indications‌: Use a tourniquet only for severe arterial bleeding (e.g., amputations, gunshot wounds) where other methods are ineffective.

2. ‌Application‌: Place the tourniquet 5-7 cm above the wound (not over joints). Tighten the strap and twist the windlass until bleeding stops. Secure the windlass in place and note the time of application.

3. ‌Duration‌: A tourniquet should not be left in place for more than 2 hours to avoid complications like nerve damage or tissue necrosis.

‌Precautions‌

• Do not apply a tourniquet for minor bleeding.

• Avoid using improvised materials (e.g., belts, ropes) unless no medical-grade device is available.

• Always seek professional medical care immediately after application.

Historical and Modern Context‌

Tourniquets have been used since ancient times, but advancements in the 21st century—driven by military conflicts and emergency medicine research—have significantly improved their safety and efficacy. Today, they are standardized in trauma protocols worldwide, including the Tactical Combat Casualty Care (TCCC) guidelines.
