The Sterilization Quality Of Cavity-type Instruments Is Related To The Way Of Sterilizers Discharging Cold Air

With the rapid development of minimally invasive surgery, various types of cavity instruments are continuously available. How to exhaust the cold air inside the cavity instruments has become an urgent task. Since then, it has been found that the version 3.0 sterilizer can no longer meet the sterilization needs of increasingly new cavity-type instruments. Because, the common sense of sterilization of pressure steam sterilizer tells us that under the premise of ensuring the quality of the steam entering the sterilizer, all the surfaces of the sterilized items (please pay special attention: the surface inside the cavity) are not the same Condensed water appears blindly, because only the surface (parts) where condensed water appears can instantaneously obtain hundreds of degrees of latent heat, which quickly heats up these surfaces, and the residual pathogenic microorganisms and other organisms instantly degenerate and die, realizing the true damp heat Sterilize.

Suppose that the cold air inside a cavity-type device is not exhausted, and the saturated steam cannot contact the surfaces (parts) occupied by the cold air. As a result, condensate will not appear on these surfaces (parts), so There is no latent heat. I believe everyone understands this common sense problem: all surfaces (parts) that form condensate are performing humid heat sterilization; and those surfaces (parts) that have cold air occupied and do not form condensate are performing dry heat sterilization. The procedure of dry heat sterilization (160 ℃ × 2h, or 180 ℃ × 30min) cannot be realized on the pressure steam sterilizer. Therefore, the steam sterilization failure of the surface (parts) where no condensed water appears is an inevitable result.
