Description

Medical protective mask

Technical Field

The utility model relates to the field of medical equipment, concretely relates to medical protective facial mask.

Background

Due to the recent epidemic influence caused by the novel coronavirus pneumonia, the mask capable of protecting the novel coronavirus is also in short market.

The masks commonly used in the market are roughly classified into the following types:

1. a cotton gauze mask.

Cotton masks have once occupied the major market. The main function of the cotton gauze mask lies in cold protection and warm keeping, and cold air is prevented from directly stimulating respiratory tract. The cotton gauze mask has good air permeability, but the dust-proof and bacterium-proof effects of the cotton gauze mask are almost not good, and if the cotton gauze mask is used in epidemic disease high-incidence period and haze weather, the cotton gauze mask has little effect.

2. Medical non-woven fabric mask.

The medical non-woven mask can be said to rapidly enter ordinary families from the beginning of SARS. The nonwoven mask is effective in preventing bacteria, and is limited to preventing bacterial infection caused by spraying, for example, preventing the transmission of bacteria caused by sneezing. However, the adhesion is poor, and the effect of preventing the spread of the droplet germs is not good.

3. An active carbon mask.

The mask is characterized in that activated carbon is added into an interlayer of the mask, the activated carbon has strong adsorption capacity and can effectively prevent bacteria and dust, but the mask can make breathing difficult, can be easily lack of oxygen after being used for a long time, has poor adhesion and has poor effect when preventing the droplet germs from spreading.

4. A dust mask.

The dustproof mask is generally in a cup shape and is generally provided with a breather valve, and the dustproof mask can be effectively attached to the mouth and nose, so that the dustproof mask has a good effect of preventing the infection of droplet viruses. But the production cost is high, the sterilization device is not generally disposable, and has certain risk of disease infection for ordinary people in the case of repeated sterilization treatment. Moreover, the breathing valve is worn by the infected patient, and the transmission of virus cannot be prevented.

Mask of N95 or above. N95 is a kind of dust mask, N indicates dust prevention, and numbers indicate efficacy, and some also have a breather valve. But the production cost is high, the sterilization device is not generally disposable, and has certain risk of disease infection for ordinary people in the case of repeated sterilization treatment. Some of them have a breather valve and are worn by the affected patient, and cannot prevent the spread of virus.

Chinese utility model patent (CN201820317048.9) has introduced a gauze mask, replaces the nexine of traditional gauze mask through the moisture absorption PET mesh non-woven fabrics that adopts an feature of environmental protection, chooses for use 22 mesh non-woven fabrics as the nexine to the waterproof aqueous vapor performance of gauze mask has been increased substantially, makes the gauze mask when having comfortable, ventilative, durable characteristic, has better antifog and waterproof aqueous vapor performance. Even roll points are arranged on the surface of the surface layer, but the roll points are not penetrated, so that the softness of the fabric can be obviously improved.

Although the mask has good protection and usability, the mask is not particularly good for virus protection because of its poor adhesion.
