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
