Patent ID: 8431077

Claim:
A Hydrogen peroxide sterilization device with hydrogen peroxide vapor injection comprising: a tank ( 6 F); a sterilization chamber ( 1 A); a dosing pump ( 5 ); an electrical valve ( 4 E); a vaporizer ( 4 G), comprising a capillary tube ( 4 D); an electrical resistance heater ( 4 A); various pressure and/or temperature sensors; a computer or control unit programmed to control a dose fed to said sterilization chamber ( 1 A) by controlling the electrical valve ( 4 E) following the dosing pump ( 5 ) taking into account information concerning the pressure and/or temperature coming from said various pressure and/or temperature sensors, and wherein the pressure inside the chamber is maintained during the sterilization process at a constant predefined value; wherein the dosing pump ( 5 ) removes the sterilant agent from the tank ( 6 F) passing it through the vaporization valve ( 4 E) and introducing it into the capillary tube ( 4 D), wherein the vaporizer ( 4 G) feeds the sterilization chamber ( 1 A) and to work with a sub-atmospheric pressure; wherein the electrical resistance heater heats the vaporizer ( 4 G); wherein the capillary tube ( 4 D) fills the sterilant agent drop-by-drop and to transform the liquid into a pulverized gas.
