Independent lab testing has confirmed that Perma Pures Nafion material effectively inhibits the growth of two common bacteria: Staphylococcus aureus and Pseudomonas aeruginosa. Both microorganisms can cause a variety of infections including, but not limited to, skin lesions, pneumonia, meningitis and endocarditis.
Nafion is used in Perma Pures ME-Series Moisture Exchangers for breath sample dryers, filters and sample lines to dry or humidify medical gas and breath sample streams. In either drying or humidifying applications, the ME-Series products seek equilibrium with room humidity, transferring water vapour into or out of the tubing in a stable, self-regenerating cycle.
In breath drying applications, such as capnography and anaesthesia monitoring, Nafions antibacterial properties reduce the risk of biological growth in sample lines, breathing circuits and within instruments. In humidification of medical gases, such as supplemental oxygen, Nafion presents a superior alternative to devices constructed of materials sensitive to bacterial growth and biofouling. As the antibacterial properties are an inherent part of Nafions molecular makeup, these properties do not degrade over time as do antibacterial coatings applied to the inside of other tubing.
ME-Series Nafion dryers remove only water vapour from gas streams, without altering or removing any of the other elements. The antibacterial membrane tubing does not require power input for operation and there are no moving parts to fail. With levels of humidification only reaching ambient conditions, there is no threat of rainout in the sample lines.
