A kind of medical low-temperature steam formaldehyde sterilization cabinet and its sterilization method

Abstract

The invention discloses a medical low-temperature steam formaldehyde sterilization cabinet and a sterilization method thereof. The medical low-temperature steam formaldehyde sterilization cabinet comprises a cabinet body, a sterilization cavity, a formaldehyde water solution medicine feeding device, a steam generator, an electric control device, an evacuating device and a clean air supplying system, wherein the sterilization cavity comprises a sterilization chamber, a heating jacket and a sterilization chamber door; the steam generator comprises a heat supply medium box; a formaldehyde vaporization pipeline, a heating device, a heat supply medium pipeline port, a low-temperature steam outlet and a waste liquid outlet are formed in the heat supply medium box; a medicine outlet pipeline of the formaldehyde water solution medicine feeding device is connected to the inlet of the formaldehyde vaporization pipeline; the outlet of the formaldehyde vaporization pipeline is connected to the sterilization chamber; the low-temperature steam outlet is connected to the sterilization chamber and the heating jacket through pipelines; the evacuating port of the evacuating device is connected to the sterilization chamber; the air supply end of the clean air supplying system is connected to the sterilization chamber. By mixing the low-temperature steam and the formaldehyde gas for sterilization at the vacuum state, the sterilization effect is complete without dead angle, and the residual formaldehyde gas can be eliminated completely after sterilizing.

Description

technical field [0001] The invention relates to a sterilizer, in particular to a medical low-temperature steam formaldehyde sterilizer. In addition, the invention also designs a sterilization method for the sterilizer. Background technique [0002] Formaldehyde has a highly effective sterilizing effect on a variety of microorganisms, including bacterial propagules, spores, mycobacteria, fungi, and viruses. Its sterilization mechanism is that formaldehyde is an alkylating agent, which can alkylate and denature the active genes of bacterial proteins, enzymes and nucleic acids. It can generate methine derivatives with amino groups, sulfhydryl groups, hydroxyl groups and carboxyl groups on protein molecules, thereby destroying bacterial proteins (especially enzymes) and causing microbial death. [0003] However, the current use of formaldehyde for sterilization is to use formaldehyde solution to fumigate the items to be sterilized to achieve the purpose of sterilization. Howeve...

AI Technical Summary

Problems solved by technology

[0003] However, the current use of formaldehyde for sterilization is to use formaldehyde solution to fumigate the items to be sterilized to achieve the purpose of sterilization. However, the sterilization effect of this sterilization method is not good, and this formaldehyde cannot be in contact with the items in all directions, especially packaging bags and belts. Lumen items, the sterilization effect is even lower, resulting in incomplete sterilization, there are hygienic dead ends, etc.

In addition, sterilized items tend to have residual formaldehyde. Once the items with formaldehyde residue are used in medicine, it will cause irreparable losses to patients.
