Pulsed steam sterilization process and steam sterilizer thereof

Abstract

The invention discloses a pulsed steam sterilization process suitable for sterilizing medical equipment and a steam sterilizer for the steam sterilization process. The sterilization process comprises the following steps of vacuumizing, preheating, sterilizing, performing vacuum drying and the like. The steam sterilizer comprises a steam sterilization box, a valve bank, an air filter, a steam generator, a vacuum pump and an automatic control system. Compared with the prior art, the invention has the advantages that: by the pulsed steam sterilization process and the steam sterilizer thereof, a sterilization apparatus can be transported without packaging, the temperature raising and reduction time of the sterilization is shortened, the sterilization time of the apparatus is shortened, the labor intensity of medical care personnel is reduced, and the disinfection and sterilization are more complete and have a better effect.

Description

technical field [0001] The invention relates to the field of disinfection and sterilization of medical instruments, specifically a pulsating steam sterilization process and a steam sterilizer thereof. Background technique [0002] At present, steam sterilizers are widely used in the sterilization of medical devices in hospitals. However, due to the limitation of the air discharge method and degree, the sterilization heating and cooling time is relatively long, and because the sterilized devices are from the sterilization point to the device use There is a certain distance between the points. In order to prevent re-contamination during transportation, it is necessary to dry and wrap the sterilized instruments. The wrapping method generally adopts pre-sterilization wrapping and post-sterilization wrapping. Pre-sterilization wrapping increases the difficulty of steam penetration. , prolonging the sterilization heating time, and at the same time, the sterilized instrument packag...

Problems solved by technology

[0002] At present, steam sterilizers are widely used in the sterilization of medical devices in hospitals. However, due to the limitation of the air discharge method and degree, the sterilization heating and cooling time is relatively long, and because the sterilized devices are from the sterilization point to the device use There is a certain distance between the points. In order to prevent re-contamination during transportation, it is necessary to dry and wrap the sterilized instruments. The wrapping method generally adopts pre-sterilization wrapping and post-sterilization wrapping. Pre-sterilization wrapping increases the difficulty of steam penetration. , prolonging the sterilization heating time, and at the same time, the sterilized instrument package must be dry before it can be taken out, which increases the difficulty of drying and prolongs the drying time, resulting in a longer sterilization cycle

Wrapping after sterilization requires high environmental cleanliness because it is wrapped outside the machine, which is prone to secondary pollution. At the same time, the wrapped instruments after sterilization also need to be dried, which prolongs the sterilization cycle
