trophon®2 offers a fast and simple solution for the high-level disinfection of ultrasound probes. Disinfection takes place in an automated, closed system and uses a sonicated hydrogen peroxide mist.
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.
Its automated functionality helps ensure consistency in your HLD process, while traceability solutions can help you meet compliance requirements.

Look to us to keep bringing you solutions that help you simplify steps, eliminate others entirely, minimize the possibility for errors and maximize compliance.

Why GE?

How it works

At the start of the high-level disinfection cycle, the trophon creates an aerosol of concentrated hydrogen peroxide. This is distributed over the exposed surface of the probe providing thorough, high level disinfection of the shaft and the handle of the probe. The trophon then breaks down the hydrogen peroxide into small amounts of oxygen and water which is evaporated into the atmosphere. During a purge, oxygen is vented into the atmosphere and water is collected in the waste container inside the trophon (maximum capacity 150ml).

The contact conditions are fixed cycle parameters that the end user cannot modify.

Complete Reprocessing Solution

GE can help you streamline the many touchpoints for reprocessing an ultrasound probe – from cleaning to disinfection to storage.

An essential first step in the reprocessing of ultrasound probes is pre-cleaning to remove gel, microbial load and other soil from the probes. Ready-to-use wipes simplify cleaning and drying steps to promote efficient HLD workflow.

trophon®2 offers a fast and simple solution for the high-level disinfection of ultrasound probes. Disinfection takes place in an automated, closed system and uses a sonicated hydrogen peroxide mist. 

The Joint Commission recommends the following for semi-critical devices: “store the device in a manner that will protect from damage or contamination and that is consistent with national guidelines and manufacturers’ recommendations6. Probe Storage Cabinets provide a dedicated and secure place to store your disinfected transducers between exams. Probe Covers protect the probe – including the handle.

Guidelines & Recommendations

“ …because condoms/probe covers can fail, the [semi-critical ultrasound] probe also should be high level disinfected.” 1


“ All internal transducers (e.g., vaginal, rectal, and transesophageal transducers) as well as intraoperative transducers require high level disinfection before they can be used on another patient.” “Because of the potential disruption of the barrier sheath, high level disinfection with chemical agents is necessary.” 2


“ Semi-critical devices…sterilize these devices between uses whenever feasible, but high level disinfection is minimally acceptable.”


“ Semi-critical devices should be sterilized, if possible. However, if sterilization is not feasible, the, device, at a minimum, must be subjected to a high level disinfection process…” 3


 “ …A new recommendation for high-level disinfection or sterilization of endocavity ultrasound probes highlights the risk for probe contamination with lower levels of disinfection, even when a sheath or cover is used. ” 4
