Through the step of creating hydronium and heavy molecule among the steps of the new sterilization method, it is possible to sterilize with the new sterilization method as a result of adsorption (molecule gas spinning) on all kinds of microorganisms and organic materials by creating hydronium and heavy molecule inside the sterilization chamber, and to safely sterilize all materials also in very long lumens without any regards to length and inner diameter while the sterilization chamber is filled with the materials to be sterilized under full load.
In the sterilization system that uses the new sterilization technique and method, safe sterilization is guaranteed with the impact of the efficient sterilization of hydronium (H30), heavy molecules (H04, H203, H204, H05, OOH, H03 etc.), radicals, hydroxyls, plasma and ions by using hydrogen peroxide (H202) and OZONE (03). Prior Art
Today, H202 low temperature sterilization equipment are used to properly sterilize surgical materials, imaging equipment and similar apparatuses used on the patients' body in hospitals and similar environments. There are various developments in the prior art about the respective machinery and sterilization methods.
In one of the related developments, the Turkish Utility Model Document numbered TR 2009/02599 describes a machine which allows for sterilizing and reusing the considered hospital materials with a hydrogen peroxide sterilization tool. In another document in the prior art, the European Patent Document numbered EP 3056224 describes a method which was developed to control the condensation (concentration) of hydrogen peroxide while sterilizing at a predefined temperature in a sterilization chamber that can be sealed. In the methods described in the prior art, following the sterilization effect of H202, ozone gas is supplied and hydroxyl is created as an outcome of which only the residue is removed.
The foregoing documents do not describe operating the equipment at full capacity through raw material distribution and adsorption inside the equipment by applying a limited and conventional sterilization method and sterilizing very long lumens under full load without any regard to length and inner diameter. Detailed Description of the Invention
A sterilization method with low temperature H202 and ozone heavy molecule hydronium gas plasma in the present invention comprises of;
A step of vacuuming which allows for increasing the vacuum to -600, -900 mBAR values in the sterilization chamber by discharging the atmospheric air after placing the materials to be sterilized into the sterilization chamber inside the equipment
