Simply smarter probe disinfection in 7 minutes.

trophon® EPR is a high level disinfection system that is fast and simple. Disinfection takes place in an automated, closed system and uses a vaporized hydrogen peroxide solution.

The compact design means it can be located at the point of care, helping to improve patient workflow, while the fully enclosed system helps protect both patients and staff by limiting exposure to harmful disinfectant chemicals. As a point of care solution, it can help reduce the need to transport probes between the ultrasound suite and separate cleaning rooms.

HPV Transmission Risks

A new study shows trophon® EPR is the first high level disinfection system for ultrasound probes that is effective against high-risk, cancer causing strains of Human Papilloma Virus(1).

Appropriate reprocessing of ultrasound probes between patients is critical to reduce the risk of HPV transmission.  Recent research shows disinfectants commonly used on ultrasound probes do not kill natural, infectious high-risk HPV(2).

Given the prevalence of HPV, the potential for HPV transmission in the healthcare setting and the virus’s links to cancer, these research developments are of concern.
