摘要:
"Method for sterilizing an article in a sealed sterilisation chamber;Release system and unit of measurement of hydrogen peroxide and container with solution of hydrogen peroxide;Method to control unwanted condensation of hydrogen peroxide in a sterile chamber,And methods for measuring a preselected volume of hydrogen peroxide (360)in a vacuum evaporator and hydrogen peroxide gas (360)in a evacuated sterilisation chamber "a method of sterilizing an article by sequential exposure of the article to peroxideOf hydrogen and ozone is shown. The article is first exposed under vacuum to an aqueous solution evaporated from hydrogen peroxide (360)and subsequently to an ozone -containing gas. The exposure is performed without reducing the content of the water vapour in the sterile atmosphereThe water vapour content being derived from the aqueous solvent of the hydrogen peroxide solution (360)and the breakdown of hydrogen peroxide in water and oxygen. The complete sterilisation process is performed while the chamber remains sealed and without removing any component of the sterile atmosphere. For this purpose,The chamber is initially evacuated at a first vacuum pressure sufficient to cause the aqueous hydrogen peroxide to evaporate at the temperature of the chamber's atmosphere. The chamber is then closed for the remainder of the sterilisation process and for all sterile injection cycles. Keeping the chamber sealed and keeping the peroxideAnd hydrogen and its chamber decay products for subsequent sterilization of ozone results in a synergistic increase in sterilization efficiency and allowing the use of much smaller amounts of sterilization and times the sterilization cycle that would be expected Using hydrogen peroxide and ozone in combination.“método para esterilização de um artigo em uma câmara de esterilização vedada; sistema de liberação e unidade de medição do peróxido de hidrogênio e recipiente com solução do mesmo; método para controlar indesejada condensação do peróxido
