An extensive list of pathogens have been implicated in healthcare-associated infections (HAIs). High level disinfection (HLD) of semi-critical medical devices such as ultrasound probes is an essential part of the fight against HAIs.
Nanosonics has conducted extensive laboratory testing to validate the effectiveness of the trophon device and its sonicated disinfectant mist technology.
As a result, trophon is the only automated HLD technology for transvaginal, transrectal surface ultrasound probes to meet mandatory microbial efficacy test requirements for both CE mark and FDA registration.
This includes testing that meets the required EN, ASTM and AOAC standards to demonstrate:1-3
In addition to mandatory testing, the trophon device is demonstrated to eliminate an extended range of clinically relevant pathogens including:
Vegetative bacteria | Fungi |
Staphylococcus aureus | Trichophyton mentagrophytes |
Pseudomonas aeruginosa |
Viruses |
Salmonella choleraesuis |
Polio virus type 1 |
Methicillin-resistant Staphylococcus aureus |
Herpes simplex virus type 1 |
Vancomycin-resistant Enterococcus faecalis | Hepatitis A virus |
Carbapenam-resistant Escherichia coli | Adenovirus type 2 |
Neisseria gonorrhoea | Human hepatitis B virus surrogate (duck hepatitis B virus) |
Chlamydia trachomatis (serotype K) | Human immunodeficiency virus type 1ϯ |
Mycobacteria | Human norovirus surrogate |
Mycobacterium terrae | Human rotavirus |
Bacterial endospores | Human papillomavirus (HPV16 and HPV18) |
Clostridium difficileϯ | Hepatitis C virus surrogate (Bovine viral diarrhea virus) |
Clostridium sporogenesϯϯ | |
Bacillus subtilisϯϯ |
ϯ the trophon device has been shown to inactivate these pathogens in laboratory tests.
ϯϯ Effective at extended contact time per FDA requirements for HLDs.
The trophon device outperforms other methods of disinfection that have been tested in similar clinical settings:4,5
The trophon® family includes trophon® EPR and trophon®2 which share the same core technology of 'sonically activated' hydrogen peroxide.
