Untangling Misconceptions about Narrow Cuffs and Safety

It has been well established in medical literature that the probability of tourniquet-related injuries increases as tourniquet pressure increases, and as the pressure gradient near the edges of tourniquet cuffs increase, e.g. [1-7]. Unnecessarily high tourniquet pressure gradients represent a serious and recognized hazard associated with unnecessarily high probabilities of patient injuries, specifically nerve injuries. [...]

Here you will learn about the best tourniquet systems, based on personalization, which provide individualized, safe and effective care for the patient. The Best Tourniquet Systems [...]

What are Internal Tourniquets?

A recent US patent for an ‘internal tourniquet for surgery’ [1] described innovation that opens the door to extending tourniquet-related concepts to surgical procedures not previously amenable to conventional tourniquets, especially procedures near truncal-extremity junctions, including hip and shoulder regions, and in the deep abdomen. Synergies exist by integrating this internal tourniquet innovation with related [...]

Tourniquets for Treating Open Fractures and Traumatic Injuries: Contraindicated or Not?

Overview: A current overview of the use of tourniquets in surgery and traumatic injury is provided elsewhere [1]. Open fractures: The use of a tourniquet is contraindicated in the surgical treatment of open limb injuries because it is necessary to make an assessment of the devascularized zone of injury for the purpose of wound management [...]

Surgical Tourniquet Instrument Technology

What is the purpose of a surgical tourniquet instrument? The purpose of a surgical tourniquet instrument is to safely and accurately supply and regulate the pressure in a tourniquet cuff. Personalized surgical tourniquet instruments: Personalized tourniquet instruments are state-of-the-art, modern pneumatic tourniquet instruments. Click here to learn about the history of tourniquets. They include automatic [...]

Tourniquet Safety: Mechanisms and Prevention of Injuries

To improve tourniquet safety for patients, it is important to know the mechanisms and prevention of tourniquet injuries. Surgical Tourniquet Safety It is reliably estimated that pneumatic tourniquets are used in more than one million surgical procedures annually in North America. The potential for injury is significant, although the use of lower, personalized tourniquet pressure [...]

Tourniquet Cuff Technology

Tourniquet Cuff Technology: What is the purpose of a tourniquet cuff? The purpose of a tourniquet cuff is to safely stop or restrict arterial blood flow into a portion of an extremity by applying a uniform circumferential pressure around the extremity at a desired location. Pneumatic tourniquet cuffs In general, a pneumatic tourniquet cuff is [...]

Tourniquet Cuff Selection

Are you selecting a tourniquet cuff that meets all FDA requirements as a Class I medical device? In the United States, pneumatic tourniquet cuffs are regulated as Class I medical device by the Food and Drug Administration (FDA). Risks of injuries to patients and legal liability for users arise from use of a pneumatic tourniquet [...]
