Sterilization apparatus using sterilizing superheated steam under normal pressure and hypoxia environment

摘要

The apparatus comprises a containing portion in which an object to be sterilized such as medical treatment tools is accommodated for sterilization; and a sterilizing superheated steam generating and supplying portion provided adjacent to the containing portion comprising a saturated steam generating portion for generating a saturated steam at 80 to 100 degrees centigrade from water, a sterilizing superheated steam generating portion for generating therein a sterilizing superheated steam at 120 to 300 degrees centigrade by colliding the saturated steam generated from the saturated steam generating portion with a heated superheating medium at a predetermined flow rate; and a sterilizing superheated steam supplying portion for feeding the sterilizing superheated steam into the containing portion, thereby forming in the inner of the containing portion heated low-oxygen environmental condition equal to or less than 3% oxygen concentration suitable for sterilizing attached bacteria, at 120 to 150 degrees centigrade under normal pressure.
