Biocote Technology


In Armstrong Medical Ltd’s efforts to reduce the risks associated with hospital acquired infections, AquaVENT® heated breathing circuits are supplied with BioCote® antimicrobial additive to limit the spread of bacterium species between patients and users, should transferable bacteria come into contact with the surfaces of the breathing circuit.


BioCote® technology in AquaVENT® heated breathing circuits uses inorganic silver ion particles dispersed homogenously throughout the polymer used to form components of the breathing circuit.


On the 9th April 2013 our manufacturing partner BioCote® issued a press release (please click here for a link to the full press release) stating they had commissioned testing of their antimicrobial technology against a carbapenemresistant Enterobacteria (CRE). Their independently-performed ISO 22196 test demonstrated elimination of over 99.9% of the bacterium Klebsiella pneumoniae. BioCote® stated that their technology has already been proven to be effective against a wide range of bacteria and fungi and this brings the total number of multi-drug resistant bacteria which BioCote® technology is known to be effective against to four:


  1. MRSA (Methicillin-resistant Staphylococcus aureus)
  2. VRE (Vancomycin-resistant Enterococcus)
  3. ESBL (Extended Spectrum Beta Lactamase producing E. coli)
  4. CRE (Carbapenem-resistant Enterobacteriaceae, Klebsiella pneumoniae)
