Medical mask with physical method for killing germs and viruses

Abstract

The invention relates to a medical mask with a physical method for killing germs and viruses. A PP non-woven fabric layer or afused cloth filter layer is arranged outside the mask; a heating materialis added, high temperature is generated to kill or weaken the activity of viruses in germs or liquid drops,electric heating carbon fiber yarns are used,the temperature of the fused cloth filter layeror the outward PP non-woven fabric layer of the mask reaches or exceeds 56 DEG C,many viruses including novel coronaviruses can be inactivated at 56 DEG C, the carbon fiber heating wires are arrangedon the outward PP non-woven fabric layer or the outward surface of the melting cloth layer tightly connected below the PP non-woven fabric layer when the target is reached; and generated heat is mainly concentrated on the outward face, the temperature of the inward face close to the face of a person is reduced to the degree that the person feels comfortable, and the temperature of the outward facecan be increased to the high temperature which is not limited to 100 DEG C.

Description

technical field [0001] The invention relates to a medical mask with the functions of killing germs and viruses with its own physical method, and belongs to the technical field of medical appliances. Background technique [0002] At present, disposable medical masks include a cover body, which is generally made of veil or sanitary gauze material. According to different needs, the thickness of the cover body is also different. Common surgical masks are generally made of PP non-woven fabric facing outwards. layer, sandwiched in the middle of the melt-blown cloth layer and the PP non-woven layer that contacts the face of the person, and the mask also has more than three layers of multi-layer masks, but the basic principle of the mask is to use the PP non-woven layer of the mask, especially It is a layer of melt-blown cloth sandwiched in the middle, which filters harmful bacteria or tiny droplets containing viruses. Taking melt-blown cloth as an example, the basic principle of me...

Problems solved by technology

The problem with existing masks is that the cloth layer of these masks includes the melt-blown cloth layer itself. The main function is to block or absorb germs or droplets containing viruses, and cannot kill these germs or droplets. With the accumulation of time, the concentration of accumulated harmful germs or tiny droplets containing harmful viruses is getting higher and higher, and the accumulated harmful germs or virus droplets are increasing, and the danger itself is getting higher and higher. Therefore, the existing The use time of medical masks is very short, and usually must be replaced within 4 hours; for highly infectious viruses with unknown risks, such as the new coronavirus with an infection coefficient of 3.0-3.6, the replacement speed of masks may be even greater, according to statistics from the Ministry of Industry and Information Technology In terms of the daily production of 20 million masks in the country, calculated by changing them every 4 hours, only 3 million masks can be changed every day, which is far from the goal of the national expert group calling for 1.4 billion people to wear masks nationwide, not to mention the current 20 million masks. Only 40% of the production capacity of masks has been restored, and it has returned to 8 million per day. Therefore, it is of great significance to develop masks that can sterilize or kill droplets containing viruses and increase the use time of masks.
