Why customers choose trophon as their high level disinfection system for reprocessing ultrasound probes.

Many decisions in life are hard, but selecting a high level disinfection (HLD) system for reprocessing ultrasound probes should be easy. trophon is the safeversatile and simple way to prevent ultrasound probe infection risk.

trophon stands out from the crowd in a multitude of ways. Here are our top 10 reasons so many customers choose to use it!

1. trophon is automated

Simply close the door and press start. It couldn’t be easier for a simple workflow. Say goodbye to mixing toxic chemicals and using manual test strips. And with no operator intervention during the HLD process, there’s minimal chance of human error or inconsistencies. You can have confidence that your probe is effectively disinfected every time.

2. trophon is fast

With a cycle time of only 7 minutes you can spend more time on the things you’d rather be doing. Just press go and off you go! No need to wait around while trophon does its thing.

3. trophon is safe

Provide your patients with the highest possible standards of care by protecting them from ultrasound probe cross infection risk. trophon is proven to eliminate an extended range of clinically infectious pathogens, including sexually transmitted infections, Clostridium difficile spores and drug resistant bacteria.1 trophon is also safe for staff, with its closed-door system protecting against exposure to toxic chemicals and fumes.

4. trophon complies with AS/NZS standards for the HLD of ultrasound probes

There are a variety of standards and guidelines to navigate when it comes to the cleaning and disinfection of medical devices. Not to mention requirements as to the documentation you need to maintain. It can be confusing but with trophon you can relax, knowing that you’ll be compliant. Not only in your high level disinfection procedure, but trophon also meets the process record requirements in AS/NZS 4187. No need to stress come audit time! 2

5. trophon protects where other methods may not

Not all high level disinfection methods are equal. As well as potentially posing health risks for users, it’s actually been shown that some common soaking disinfection chemicals (like OPA and GTA) do not work against the high risk strains of HPV.3

trophon was the first system in the world proven to kill high-risk, cancer causing HPV.4

Ultraviolet (UV) light solutions have their limitations too, with the European Society of Radiology Ultrasound Working Group recently stating that “UV light is less effective in eradicating microbes in comparison to hydrogen peroxide”.5

6. trophon is probe friendly

Over 1,000 surface and endocavity ultrasound probes (across all major manufacturers) are compatible for use with trophon. Nanosonics conducts extensive testing, in partnership with your ultrasound probe makers, to ensure the life of your expensive probes will be preserved.

There is no exposure to harsh liquid chemicals or UV light during HLD with trophon. The same can’t be said for other methods. For example degradation of plastics and rubbers can occur if probe materials are not compatible with UVC light.

7. trophon is environmentally friendly

trophon provides a unique, patented ‘greener’ high level disinfection (HLD) technology, which significantly reduces the use of toxic chemicals in healthcare facilities around the world (compared to traditional ultrasound probe reprocessing methods). With recyclable components and the generation of environmentally friendly by-products (primarily water and oxygen), trophon prevents chemicals being dumped into the environment and allows for the easy, safe disposal of waste. In the US for example, each trophon prevents 372,000 litres of chemicals being dumped into the environment.

Our efforts in this area have been publically recognised, with Nanosonics recently winning the Environmental Solutions Awardat The Premier’s NSW Export Awards.

8. trophon can live anywhere!

With its small compact size and adaptable nature, trophon can fit in a variety of locations including examination rooms. With no requirements for sinks or special ventilation it makes convenient point of care (POC) disinfection a reality. POC reprocessing takes away the painful task of having to transport your probes to and from central reprocessing areas too – just another time saving!

9. trophon is setting a global standard of care

Now found in all of the top US hospitals, increasingly being adopted across NHS trust hospitals in the UK, as well as being used in many private health care clinics across the globe, isn’t it time you joined the trend?

Over 40,000 probes are trophoned a day in the US alone.

10. trophon may be taking over the world, but it remains proudly Australian made

Invented here and manufactured here, trophon is a true down under success story. Our operations now span the globe but we maintain our head office in Sydney.
