In the continued fight against Hospital Acquired Infections, Intersurgical has developed the Silver Knight range of products with an anti-microbial additive to further enhance patient safety. This anti-microbial, silver-based ion additive has been introduced to a range of breathing systems for both anaesthesia and intensive care use. Testing to ISO Standard 22196 shows a reduction in bacterial viable count by 99.9% against controls.

How does it work?
Silver Knight is an anti-microbial additive that uses silver ions to disrupt the normal enzymatic activities of bacteria. It functions as a safe, quick and effective catalyst to deactivate pathogenic bacteria and prevent their proliferation. This technology allows the ions to be released in small quantities over time to reduce microbial growth within, and on, the surface of the breathing systems. Silver Knight breathing systems are all validated for up to seven days use, and remain active, in unopened packaging, for up to five years.

Silver Knight is proven(1)  to help reduce the incidence of MRSA infection and other organisms including:
• Staphyloccus epidermis
• Pseudomonas aeruginosa
• Klebsiella pneumoniae
• Acinetobacter calcoaceticus
• Escherichia coli

UniFlow can now be used on paediatrics to as low as 5kg in weight.  View this document under the download tab.
