About the AT4™

Ideal for single or bi-lateral orthopaedic surgery and pain management

Intuitive and simple to use.

Compact, light weight and robust, offering advanced technology combined with maximum safety and reliability.

The AT4™ Electronic Tourniquet is a truly independent device operating from its own integral air supply, so no need for air supply hoses, medical air cylinders or power leads. Engineered to use minimum power, the 25 hour battery can be in use all day without the need to recharge until the end of the list. The battery provides more than back-up: it’s independence and reliability.

The Tourniquet has sensitive leak compensation facilities as well as automatic self-diagnostic checks on start-up, which means it is calibrated every time it is switched on. Cuff channel hoses and displays are all colour coded for ease of recognition.
