Sterilization method of steam sterilizer and steam sterilizer

Abstract

The invention discloses a sterilization method of a steam sterilizer and the steam sterilizer. The steam sterilizer comprises a sterilization cavity (6), an interlayer (7), and an injector vacuumizing unit, and is characterized by also comprising a sterilization cavity interlayer air inlet unit, a sterilization cavity air return unit, a sterilization cavity drainage unit, a sterilization cavity vacuumizing unit, an interlayer steam inlet unit and an interlayer drainage unit. The sterilization method comprises the specific sterilization steps: 1, preheating; 2, performing positive pulse replacement; 3, performing negative pulse replacement; 4, pulsing; 5, raising the temperature; 6, sterilizing; 7, exhausting; 8, drying; 9, returning air; and 10, ending. According to the sterilization method disclosed by the invention, rapid and high-efficiency sterilization can be realized through the steam sterilizer with a water injector.

Description

technical field [0001] A sterilization method for a steam sterilizer and a steam sterilizer belong to the technical field of steam sterilization. Background technique [0002] The steam sterilizer that uses saturated steam to sterilize is a common sterilizer on the market. In the steam sterilizer, an evacuation unit needs to be installed to clean the steam in the sterilization chamber and the condensed water generated during the sterilization process. Evacuate. At present, common steam sterilizers generally use water ring vacuum pumps to evacuate the sterilization chamber, and water ring vacuum pumps are used to evacuate, mainly due to the following defects: 1. The water ring vacuum pumps work with relatively large noise and high power at the same time , had a greater impact on the staff. 2. The drainage and exhaust pipelines are under positive pressure and high temperature during evacuation, so there are certain safety hazards. Due to the above defects, the sterilizer is ...

AI Technical Summary

Problems solved by technology

At present, common steam sterilizers generally use water ring vacuum pumps to evacuate the sterilization chamber, and water ring vacuum pumps are used to evacuate, mainly due to the following defects: 1. The water ring vacuum pumps work with relatively large noise and high power at the same time , had a greater impact on staff

2. The drainage and exhaust pipelines are under positive pressure and high temperature during evacuation, so there are certain safety hazards. Due to the above defects, the sterilizer is not suitable for some occasions, which limits the use of the sterilizer

[0003] In view of the above defects, some low-noise alternative products have begun to appear, and steam sterilizers using water jets are one of them, but there is no relatively complete set of sterilization methods for water jets, so to a certain extent The development of steam sterilizers with water injectors is restricted
