Description

Forehead totally-enclosed replaceable personal protective mask

Technical Field

The utility model relates to the technical field of medical machinery, in particular to a forehead totally-enclosed replaceable individual protective mask.

Background

Medical staff wear the mask to protect their health because of various germs and easily infected germs in the air in the special working environment. At present, the protective face mask used by basic medical staff mainly uses low-protection-level dustproof half face masks, and the two types of the protective face masks are generally used, wherein one type of the protective face mask is made of pure cotton absorbent gauze or knitted fabric, and various non-woven fabrics are clamped between the surface of the protective face mask and the knitted fabric; the other mask is directly sewn by non-woven fabrics, the filtering effect of the two masks is good, the air permeability is slightly poor, the latest variety is that the surfaces and the back surfaces are made of non-woven fabrics, the middle part is made of filter paper, and virus protection is carried out in a physical isolation mode, so that the filtering effect of the non-woven fabric mask is higher than that of a typical mask with the type of N95 or above, for example, the filtering effect of the non-woven fabric mask on non-oily particles is not less than 95%.

However, the protective mask can only protect the mouth of the wearer, but cannot protect the eyes or the mouth and nose of the wearer against viruses which can be infected by droplets through saliva, body fluid, blood and the like, the wearer usually needs to wear additional goggles to protect the eyes or the mouth and nose, and germs which infect the protected person through gaps in the vertical direction are difficult to protect against the droplets which are adhered to the hair; meanwhile, the breathing space of a wearer is limited in a smaller range by a common simple protective mask, and the mask has the functions of overcoming component resistance by breathing of the wearer, filtering particles in air, and blocking droplets, blood, body fluid, secretion and the like, so that the mask is not friendly to people with heart or respiratory system difficulties (such as asthma and emphysema), pregnant women, dizziness after wearing, dyspnea, sensitive skin and the like. Meanwhile, because the mouth part corresponding interface is not provided, the mask needs to be taken off when people take food, the use is inconvenient, and due to the protection principle, the mask is difficult to clean and can only be used once, so that the reuse is difficult to realize.

At present, the medical field also has a totally enclosed protective mask for wrapping the protective mask of the face of a wearer, but the general sealing is extremely strong, and the protective mask is connected with a protective suit to carry out all-around protection. However, such a totally enclosed protective mask is costly and is not suitable for primary medical scenarios where only splash protection is needed.

To sum up, the medical protective mask which can be used for preventing splashing and has the advantages of vertical protection, low cost, reusability, strong protection and comfortable wearing is not available in the market at present.
