Medical mask with sterilization effect

Abstract

The invention discloses a medical mask with a sterilization effect. The mask comprises a face body and tensioning belts fixed to the two sides of the face body. The face body comprises a protective layer, a needle-punched cotton layer and a skin-friendly layer. The protective layer comprises an isolation layer, a forming layer and a sterilization layer from outside to inside; wherein the isolationlayer is formed by mixing PP materials and spandex filaments, the forming layer is made of nylon, the sterilization layer is formed by mixing copper fibers and spandex filaments, the needle punchingcotton layer comprises non-woven fabric, an antibacterial layer and non-woven fabric which are sequentially overlapped, and the antibacterial layer is formed by mixing copper fibers and flax. The medical mask with the sterilization effect can effectively block and kill outside bacteria and viruses, reduces the probability of secondary infection, is high in flexibility and high in fitting degree with the face, and can guarantee the comfort of long-time wearing and the effectiveness of protection.

Description

technical field [0001] The invention relates to the technical field of medical masks, in particular to a medical mask with self-contained sterilization effect. Background technique [0002] At present, almost all medical masks on the market are made of several layers of non-woven fabrics. Such masks can only block bacteria and viruses to a certain extent, but cannot kill bacteria and viruses. The environment of the hospital is complex, and there are many kinds of viruses and bacteria. As the wearing time prolongs, the germs on the surface of the mask will accumulate more and more, and the bacteria filtering performance will become weaker and weaker, because the mask cannot kill the germs on the surface, and it will also make the mask lose protection performance. At the same time, the bacteria and viruses attached to the surface of the mask can easily cause secondary transmission, bringing harm to medical staff and patients. In addition, when wearing a medical mask requires...

Problems solved by technology

[0002] At present, almost all medical masks on the market are made of several layers of non-woven fabrics. Such masks can only block bacteria and viruses to a certain extent, but cannot kill bacteria and viruses.

The environment of the hospital is complex, and there are many kinds of viruses and bacteria. As the wearing time prolongs, the germs on the surface of the mask will accumulate more and more, and the bacteria filtering performance will become weaker and weaker, because the mask cannot kill the germs on the surface, and it will also make the mask lose Protection performance

At the same time, the bacteria and viruses attached to the surface of the mask can easily cause secondary transmission, bringing harm to medical staff and patients

In addition, when wearing a medical mask requires airtightness and protection, it cannot take into account the comfort of wearing and the smoothness of breathing, resulting in severe depression and extreme discomfort in facial muscles for people who wear masks for a long time

[0003] Patent No. CN 108308758 A discloses a method for preparing an antibacterial mask filter, specifically disclosing that antibacterial powder is filled in the middle of two layers of non-woven fabrics that make up the mask. The fiber surface layer, the first base non-woven fabric layer, and the second base non-woven fabric layer are stitched or press-fitted. The direct addition of plant antibacterial powder in the patent document will make the mask thick, which is not conducive to breathability, and The added powder is easy to ooze out, which will irritate the respiratory system and cause respiratory system damage

[0004] Patent No. "CN104957806A" discloses a reusable photocatalyst medical protective mask for sterilization, anti-virus and odor removal. Supercritical nano-scale photocatalyst coating is arranged on the outer surface of non-woven fabric or cotton yarn fabric layer. The upper and lower ends of the non-woven fabric or cotton yarn fabric layer are equipped with a skeleton, so as to effectively kill bacteria, viruses, remove odors, prevent pollen, dust, air-conditioning allergies, and inhibit infectious viruses; with the development of domestic technology in recent years Progress, there are more and more medical protective masks with bactericidal properties, but after long-term use, the photocatalyst activity in them decreases, which affects the killing rate of bacteria, viruses, etc.
