Description

Reusable sterilization channel mask

Technical Field

The utility model relates to a daily gauze mask of wearing, in particular to a sterilization channel gauze mask which is made of microporous breathable material with sterilization channel and full through and can be reused after sterilization.

Background

The use of protective products such as masks is being emphasized in order to prevent pneumonia, for example, cross-infection with the novel coronavirus pneumonia (COVID-19). The coronavirus has a small particle size, an average particle size of 100 nm and is easy to permeate through general protective materials to invade human bodies, so that the coronavirus is particularly important for protecting specific personnel, such as medical personnel, workers in isolated disease areas, workers in medical observation places, confirmed case transfer workers, epidemiological investigators, specimen collection workers, workers in biosafety laboratories and the like, which need to wear N95 masks, and all the personnel in and out of public places need to wear masks for protection.

The common mask in the existing market mainly uses a plane type mask as a main part, and can be divided into the following parts according to the material structure: cotton gauze mask, non-woven fabric mask, high polymer material mask, activated carbon powder filter element mask, and activated carbon fiber felt pad mask; the mask mainly has a double-layer structure according to the type of processing technology: non-woven fabrics, nose bridge ribs and ear hangers; three-layer structure gauze mask: non-woven fabrics, nose bridge ribs, ear hangers and filter paper; four-layer structure gauze mask: non-woven fabrics, nose bridge tendons, ear hangers, filter paper, activated carbon filter paper and the like.

1. The cotton gauze mask is mainly made of cotton yarn woven and formed cotton gauze, large particles can be blocked by mechanical blocking of one layer, harmful gas, smell and spray can be blocked by the mechanical blocking of the cotton gauze mask, the cotton gauze mask is a fiber mask in the warp and weft directions, the flow blocking principle of the cotton gauze mask is a mechanical blocking effect, but particles with the diameter smaller than 5 microns cannot be blocked, the application range of the cotton gauze mask is limited, and the cotton gauze mask can only be used as a common protective article worn outside daily.

2. The non-woven mask is made of non-woven fabric, and is made up by using high-polymer slice, short fibre or filament to make fibre into net by means of air flow or machine, then making it undergo the processes of water-jet entangling, needle-punching or hot-rolling reinforcement and after-treatment. The material is a novel fiber product with soft, air-permeable and plane structure, has the advantages of no generation of fiber scraps, toughness, durability, silky softness, reinforcement and cotton feeling. The non-woven fabric is distinguished from a general non-woven fabric and a medical non-woven fabric, and the general non-woven fabric and the cotton fabric are cheaper than each other, but the mask made of the non-woven fabric has only dust-proof capability and no anti-virus capability, and the anti-virus mask is used for filtering dust, gas, spray and the like, so that the non-woven fabric mask cannot prevent viruses when being worn. Compared with common non-woven fabrics, the medical non-woven fabric has the function of blocking bacterial particles due to different processing technologies, and the manufacturing technology of the medical non-woven fabric is characterized in that the medical non-woven fabric is manufactured by polymer feeding, melting and extruding, fiber forming, fiber cooling, net forming and cloth reinforcement, fibers in the medical non-woven fabric are fixed, formed gaps are stable, and the medical non-woven fabric can play a role in filtering pathogens such as viruses and bacteria. The mask made of the material can be selected as a first choice of a medical protective mask when respiratory infectious diseases are prevalent, is suitable for protecting the respiratory infectious diseases transmitted by air by medical staff and related workers, is a self-absorption filtering type medical protective article with high sealing performance, has high protection level, and is particularly suitable for being worn by patients who contact respiratory infectious diseases transmitted by air or transmitted by droplets at a short distance in diagnosis and treatment activities.

3. A high polymer material mask is a novel high polymer mask made of polytetrafluoroethylene materials. This material can pass through physical screening effect with PM2.5 to PM0.3 with 100~200 nanometer aperture, with the particulate matter separation on the gauze mask top layer, with the help of superstrong self-lubricity characteristic, exhale every time, all can be in the reverse particle with attached to on the gauze mask top layer push back the environment and go, so relapse, do not rely on electrostatic absorption, really reached effectual PM2.5 protective effect. The mask is suitable for basic protection of medical staff and related staff, and protection for preventing blood, body fluid and splash from spreading in the invasive diagnosis and treatment operation process, and has certain respiratory protection performance. But is limited by the fact that it is disposable, which considerably limits the development of its application field.

4. An activated carbon powder filter core mask is a dust mask, mainly prevents dust, smoke, fog, microorganisms and the like, and is divided into grades of KN100, KN95 and KN90, wherein the grade of KN100 can effectively prevent the ultramicro dust rate by more than 99.97%.

5. The gauze mask with felt pad of activated carbon fiber is a kind of oil-smoke-proof gauze mask, which mainly prevents oil smoke and mist, and at the same time can prevent dust, smoke, mist and microbe. The main function of the mask is basically similar to that of an active carbon powder filter element mask.

The five types of masks have advantages, but have obvious defects, and are all disposable and cannot be reused. Therefore, the technical level needs to be deeply researched, perfected and improved, so that the dust-proof and virus-proof plastic bag can not only prevent dust and viruses, but also achieve the effect of repeated use through disinfection.

In view of the above, the development of a reusable sterilization passage mask has become a new objective sought by researchers in this field.
