Let’s start!

THI was founded in 2009 by a group of professionals who set out to develop and produce the world’s most desirable personal protection system for use in total joint arthroplasty procedures.

Developing the two fan system

This system would support surgeons, helping them to perform at peak level while offering superior protection. The resulting Oxygen Safety System provided significantly improved comfort by actively removing hot, moist waste air through a second fan. A patent protects the 2-fan system.

Winning innovation awards and gaining market share

The award winning Oxygen Safety System is now sold in more than 20 countries worldwide.

Sure, we can do it even better

Based on valuable feedback from our users, we started in 2015 to work on the next generation. We challenged everything, listened carefully to our users, and literally started from scratch. The new system would redefine the surgical helmet market.

The new standard for a surgical protection system

In May 2017, we unveiled the new ViVi™ system. It sets a new standard on many levels. Its carbon composite frame provides a resilient, incredibly light structure weighing only 370 grams or a little less than a pound. The meticulously crafted intake and exhaust system are the quietest on the market, providing a significantly increased air exchange rate and, more importantly, 100% fresh breathing air, with no recirculation of waste air. A large field of vision, a patented hands-free gesture control, and activity sensing technology make ViVi the most innovative solution currently available. Learn here more…

We do believe, that...

Far too many patients and surgeons still risk infection during surgery and we can do something about that.
Personal protection systems can never be comfortable enough to use, in fact comfort is as important as protection, because a lack of comfort can lead to a lack in focus and subsequently to a decline in user performance.
Continually challenging the status quo with radical new designs is the only way to improve product performance.
Listening actively with intense observation is the key to uncover and understand real user needs.
Being responsive to user feedback and acting quickly is the foundation of our user satisfaction.
Maintaining an appreciative and supportive “happy microcosm” inside our company is the foundation for exceptional results.
