METHOD OF STERILIZATION USING PRETREATMENT WITH HYDROGEN PEROXIDE

摘要

A method for hydrogen peroxide vapor sterilization of medical devices a nd similar instruments having long narrow lumens or diffusion restricted areas includes the step of pretreating the article to be sterilized with a dilute solution of hydrogen peroxide prior to exposure to a vacuum or a vacuum followed by plasma. The method is such that, upon vaporization of the solution caused by the vacuum, the hydrogen peroxide remains in contact with the article for a time sufficient to achieve sterilization.
