Description
Technical Field
The utility model belongs to the technical field of medical disinfection and specifically relates to a portable VHP gauze mask sterilization degassing unit.
Background
The importance and limitation of the current mask disinfection: in the face of new coronavirus and other infectious diseases, one of the most effective protective measures is to wear an N95 mask, and an N95 mask is a non-oil-resistant mask certified by NIOSH (National Institute for acquired Safety and Health), and the filtering effect of the mask can reach 95%. Because it is disposable, the wearing time can not be overlength, and overlength can cause inside bacterium virus to adhere to too much, leads to the infection risk, but in the outbreak of epidemic situation makes it if meet the not enough condition of N95 gauze mask quantity, carries out safe effectual gauze mask disinfection and also is an important solution. Many sterilization methods for N95 masks are currently being investigated.
Research shows that the N95 mask is disinfected by high-temperature steam, so that the N95 mask can be deformed, loosened, aged and damaged in filtering property, the requirement on air tightness cannot be met, and the prevention effect cannot be achieved. The use of 70% ethanol spray to sterilize N95 masks can destroy the integrity of the mask, and the mask sterilized with ultraviolet light or dry heat at 70 degrees celsius, after three sterilizations, begins to show problems of fit and seal. But studies showed that the mask treated with VHP had no failure. Also, studies at the university of Duke in the United states have shown that sterilization of used N95 masks with vaporized hydrogen peroxide is a safe and effective method.
Hydrogen peroxide (hydrogen peroxide), formula H2O2. Pure hydrogen peroxide is light blue viscous liquid, can be mixed and dissolved with water in any proportion, is a strong oxidant, and is a colorless transparent liquid, and the aqueous solution is commonly called hydrogen peroxide. Hydrogen peroxide is a powerful disinfectant and germicide that penetrates the cell wall by passive diffusion and then denatures proteins, DNA, and other parts of the bacterial cell. It can be decomposed into oxygen and water, and is harmless to environment and has no toxic by-products.
N95 masks may be sterilized using vaporized hydrogen peroxide, which allows the hydrogen peroxide to penetrate into the material layer to kill the virus, but does not thereby degrade the protective qualities of the mask.
Vaporized Hydrogen Peroxide (VHP) is a 35% liquid Hydrogen Peroxide that is Vaporized by heating to 130 degrees celsius and the vapor phase Hydrogen Peroxide is diffused in the space. Hydrogen peroxide produces free hydroxyl radicals during vaporization, which oxidatively destroy cellular components such as lipids, proteins and DNA. The gaseous hydrogen peroxide has the capability of killing various microorganisms such as bacteria, fungi, viruses and the like at normal temperature. The vaporized hydrogen peroxide can achieve 6-log killing rate of bacterial spores, including clostridium difficile and other common hospital bacteria, such as MRSA, VRE, Acinetobacter baumannii and various viruses.
After the vaporized hydrogen peroxide is sterilized, the surface sampling shows that the sterilizing agent can eradicate pathogens of common nosocomial germs such as clostridium difficile. Besides the mask, the vaporized hydrogen peroxide can also be used for disinfection of medical environments, medical instruments and the like.
The current N95 mask vaporized hydrogen peroxide disinfection device at abroad uses a large container as a disinfection space carrier, and is inconvenient to transport and install.
