Smart ET Electronic Tourniquet: How It Stops Bleeding Fast and Safely

The Smart ET is a next-generation electronic tourniquet designed to make life-saving intervention possible in just a few steps. It can be used by anyone—no medical training required. Its intelligent technology ensures the right tension is applied to stop bleeding safely and effectively.

Unlike traditional tourniquets, Smart ET automates the application process with a smart BOA mechanism, a built-in timer, and a system that adjusts tension based on limb size. The result is quick, safe bleeding control in critical moments—without mistakes.

How Smart ET Works in Emergency Situations

The Smart ET is designed for simplicity. In an emergency, the user places the tourniquet above the bleeding site on the arm or leg and pulls the strap tight. Then, by turning the BOA knob, the system begins measuring the limb's circumference.

As the knob is turned, the tourniquet automatically determines the correct amount of pressure based on the limb size. When proper pressure is reached, a clicking sound is heard—indicating that no more tightening is needed.

Once the tourniquet is secured, an automatic timer starts. This timer uses both light and sound signals to alert the user or emergency responders. It begins counting once the turning stops, giving a warning after 1 hour and every 15 minutes afterward. This ensures that the tourniquet is not left on too long, which can lead to complications.

The device works on both arms and legs, adjusting its tension accordingly. In just a few seconds, Smart ET gives anyone the ability to control bleeding safely.

Why Smart ET Is Different from Traditional Tourniquets

Traditional tourniquets often require special knowledge to apply correctly. Too loose, and the bleeding continues. Too tight, and the limb may be damaged. Smart ET solves these problems with automatic tension control, which removes guesswork entirely.

Its reusable design also sets it apart. After use, the tourniquet can be reset by pressing a designated button and extending the strap fully. This makes it practical for repeated use in professional and civilian first-aid kits.

There’s no need to memorize steps or undergo training. The built-in guidance—through tension feedback and time alerts—ensures every application follows safety guidelines. It also removes the fear and uncertainty often felt by untrained users during emergencies.

Whether used in traffic accidents, public places, or workplaces, Smart ET ensures proper use every time—something even trained professionals can struggle with under pressure.

Technology Behind Smart ET’s Performance

Inside the Smart ET is a miniature control system with a CPU, power source, LED indicators, and a buzzer. These elements work together to monitor application status, timing, and alerts.

The tension mechanism includes a steel line within the BOA system, supported by a vertebrae-like coil that evenly distributes pressure across the limb. A silicone sleeve protects the internal components and provides grip, even in wet or slippery conditions.

The outer body is made of medical-grade plastic, while the strap is reinforced with high-strength fabric. Each part is carefully engineered to support real-time emergency response, with safety and reliability built in.

The waterproof glass over the screen and anti-slip casing add extra durability. Smart ET is designed to work anywhere, in any conditions.

A Smarter Tourniquet for Real-World First Aid

Smart ET takes the traditional tourniquet and redefines it for today’s needs. With intelligent pressure control, automatic timing alerts, and easy reuse, it empowers anyone to act fast in life-threatening situations.

Instead of hesitation and mistakes, Smart ET offers confidence and clarity. Whether you're in a car, at work, or in a public space, this tool gives you the power to stop bleeding quickly and safely—before help arrives. It's not just smart; it's life-saving.
