STERILISATION DEVICE WITH MEMBRANE VAPOUR CONCENTRATOR

摘要

Methods for disinfecting or sterilizing an article are provided. One method includes vaporizing a solution comprising a biocide in a solvent having a first biocide:solvent ratio, directing a flow of the vapour to a first side of a membrane; directing an alternate flow of gas to a second side of the membrane to increase the first biocide:solvent ratio on the first side to a second biocide:solvent ratio greater than the first biocide:solvent ratio thereby producing a concentrated vapour on the first side of the membrane, and contacting the article with the concentrated vapour for a time sufficient to disinfect or sterilize it.
