An automated high level disinfection system is the preferred option over a manual multi-wipe system

Released in February 2017, the Guidance for Decontamination of Semi-critical Ultrasound Probes; Semi-invasive and Non-invasive Ultrasound Probes, issued by the Health Services Executive has far reaching effects for ultrasound probe reprocessing. It recommends an automated validated process for decontaminating reusable invasive medical devices.

Why the guidelines are recommending high level disinfection

After manual cleaning, HLD should be performed on semi-invasive ultrasound probes and non-invasive probes that come in contact with mucous membranes or broken skin. These probes are categorised as semi-critical probes as defined by the Health Service Executive Guidelines.

Switch to trophon® EPR, an automated high level disinfection system to meet guideline requirements

A safe, versatile and simple way to prevent ultrasound probe cross-contamination

For health facilities, trophon offers disinfection confidence due to its patented technology that effectively eliminates the minimum regulatory microorganisms. It is also proven to kill high-risk, cancer causing human papillomavirus (HPV)1.

In the workplace, trophon is a highly effective safe and simple to use system. Its compact size, ensures flexible installation options as well as fitting easily into clinical process workflows. Importantly, trophon is validated for use with an extensive suite of

ultrasound probes across all major ultrasound manufacturers. Simple to operate with a one touch set-and-forget operation, the system also offers the added advantage of an inbuilt traceability solution for auditing requirements.

HPV fast facts

  • Studies have demonstrated up to 7% of probes remain contaminated with HPV despite the use of probe covers and routine disinfection.2-4
  • HPV causes 5% of all cancers worldwide.5 HPV 16 and 18, together, are responsible for 99.7% of all cervical cancers.6
  • HPV is a very stable virus and is able to remain infectious on surfaces for days, even when treated with common disinfectants.7
