For over 40 years, the Delfi team has been committed to advancing the safety and performance of tourniquet systems.

Our journey began with recognising hazardous surgical tourniquet devices on the market and the need for improvement. This led us to the development of the microprocessor-controlled automatic surgical tourniquet system. Today, our patented tourniquet technologies are used in critical life-saving procedures, operating rooms, professional and collegiate sports teams, and rehabilitation centres around the world.

Whether the progress helps a single person or millions, our mission is to address unmet needs and support healthcare professionals in delivering personalized, safe, and effective care to their patients.

We are dedicated to staying in control and remaining curious—we keep innovating.
