trophon is the safe, versatile and simple way to prevent ultrasound probe cross-infection.


trophon delivers safety for patients, staff and the environment – reduces risk

With the ever increasing challenges in the fight against the spread of Healthcare Acquired Infections (HAIs), trophon’s powerful disinfection technology is setting a new benchmark in protecting patients. All the while safeguarding staff and our environment from the dangerous hazards and toxic side effects of traditional disinfection methods.


trophon reduces the risk of ultrasound-related cross-infection in your facility.

  • Highly effective bactericidal, fungicidal and virudical high level disinfection to reduce the risk of patient cross contamination
  • Proven to kill high-risk HPV1
  • Study showed that trophon meets a range of international standards for high level disinfection2
  • Offers a safer patient environment as infection risk in a healthcare facility is greatly reduced
  • Automated closed system minimizes patient exposure to chemicals

“Before trophon we were using various methods one of which was soaking the probes in chemical solution. It wasn’t very satisfactory as we could only disinfect part of the probe [the shaft]. With the trophon EPR I can be assured that I’m giving patients the best service all round including, most importantly, the best disinfection procedure for probes.”Dr Andrew Ngu, Principal of East Melbourne Ultrasound, VIC, Australia and President elect for the International Society of Ultrasound in Obstetrics and Gynecology (ISUOG).

Human Papillomavirus (HPV) is widespread, with around 79 million Americans currently having some form of the virus1 .

It is extremely infectious and some high-risk strains can lead to significant health problems. HPV is well known as a leading cause of cancer, with virtually all cervical cancers (more than 99%) caused by high-risk HPV2.

Many people know that HPV is a sexually transmitted disease. However, it can also be passed on through non-sexual contact, for example via contact with skin or mucus. This means that HPV could be spread from one patient to another via ultrasound probes, if the probes are not adequately disinfected before use. It’s a concerning thought.

HPV poses a critical clinical risk and is a real challenge for those working in infection prevention.

trophon minimizes staff exposure to hazardous chemicals, fumes and spills.

  • Closed system
  • Sealed disinfectant cartridge that remains sealed until inside trophon
  • No manual test strips
  • May eliminate the need for special ventilation
  • May help reduce requirements for Personal Protective Equipment


trophon offers a unique ‘closed’ system for the high level disinfection of ultrasound probes.

Disinfection takes place within a compact, closed-door decontamination chamber, utilizing a sealed disinfectant cartridge.

Operators simply load the probe, close the door and press a button to start.

A small and controlled dose of sonicated hydrogen peroxide mist is then released into the chamber, which swirls around to completely cover both the probe and handle. This ultrafine, supercharged mist works inside the chamber to kill viruses, bacteria and fungi by reacting with their cells. trophon’s intelligent control unit enables sensors to monitor temperature, mist volume and flow rates throughout the process, all within the closed device.

No external user intervention is required. As everything happens inside of trophon, there is no manual soaking or mixing of chemicals.

trophon minimises exposure to nasty fumes. We are proud to meet Occupational Safety and Health Administration (OSHA) – Permissible Exposure Limits. EH40/2005 Workplace exposure limits.


trophon generates environmentally friendly by-products (primarily water and oxygen) for safe and easy disposal.

  • Patented system breaks down the Sonex mist into oxygen and water
  • Sonex-HL™ cartridges are recyclable
  • More than 70% of trophon components are recyclable
  • Small discharge tray for easy disposal of environmentally friendly by-products



trophon streamlines set-up, workflow and has extensive probe compatibility – reduces cost

The best technology in the world isn’t much use if it is difficult to install, set up and maintain.
trophon’s compact, self-contained design allows High Level Disinfection to be conducted just about anywhere you need it. There’s no complex installation and no plumbing to a water supply required.  Just plug it in and trophon is ready to go. It’s that easy!


trophon can be set up easily in a wide range of locations, including at the Point of Care.


  • Compact size – fits in examination rooms
  • No need for sink or plumbing
  • Installation options: wall, bench, cart mount
  • May eliminate the need for special ventilation
  • No open chemicals that could spill



trophon streamlines practice workflows to maximize patient throughput and cost effectiveness.

  • Simple workflows for faster turnaround without sacrificing safety, compliance or effectiveness
  • Automated closed disinfectant system
  • Compact size with a plug and play design to fit workflow
  • Best practice for POC workflow
  • Less time putting on/changing PPE

trophon’s closed automated system streamlines practice workflows to maximize patient throughput and cost effectiveness.

Other high level disinfection methods involve manual, time-consuming processes which can be challenging for staff. Extensive Personal Protective Equipment (PPE) is required, dedicated reprocessing areas with plumbing and special ventilation are needed. Probes are required to be transported between areas, increasing the risk of damage. These manual processes take time and enhance the opportunity for error. There are the associated health risks for staff, with chemical exposure a concern. As well as environmental considerations regarding the disposal of toxic chemicals used in a soaking process.

With trophon it’s easy. Simple workflows allow for faster turnaround without sacrificing safety, compliance or effectiveness.


Validated for use with more than 1,000 surface and intracavitary ultrasound probes across all major manufacturers.

  • Extensive probe compatibility testing with OEM final approval
  • Preserve the life of your valuable ultrasound probes
  • Easy to check if your probe is compatible for use with trophon

“As the clinical educator for a multi-site clinic system, I am continually looking for ways to improve work flow, reduce potential exposures to our staff of sonographers, and upgrade our disinfection process in the interest of providing the best patient care. The trophon EPR is ground-breaking, and gives an ultrasound department its first technology-driven disinfection process.”Candace Goldstein, Sonographer Educator, Scripps Clinic (part of Scripps Health), San Diego, CA. USA


trophon delivers consistent, high level disinfection to maximize compliance with guidelines and accreditation standards.


Simple workflows for quicker turnaround without sacrificing safety, compliance or effectiveness.

  • 7 minute automated cycle
  • Innovative and fast-acting sonically activated Hydrogen Peroxide Mist
  • Disinfection of both handle and probe in one step
  • No time wasted with extra PPE and probe transport
  • Point of Care placement simplifies workflows even further

“An analysis at the Oschner Clinic showed that the fast 7 minute point-of-care-disinfection process of the trophon EPR saved 18 minutes per ultrasound probe disinfection, or 7.5 hours per week when compared to glutaraldehyde soaking. The researchers also found that the trophon EPR was more cost-effective than glutaraldehyde soaking if just 1.5 extra examinations were performed within the additional 7.5 hours of time saved each week.”Johnson et al., Evaluation of a Hydrogen Peroxide-Based System for High-Level Disinfection of Vaginal Ultrasound Probes, Journal of Ultrasound Medicine, 32:1799-804, 2013.
