Description

Medical protective mask
Technical field
The utility model is about a kind of protective mask, especially about a kind of medical protective mask with wet, blocking solution, fire-retardant, antistatic, dustproof, anti-virus functionality.
Background technology
At present, common protective mask generally adopts one or more layers cotton gauze or other fabric to make.No. the 01278824.4th, Chinese patent is disclosed promptly to be a kind of mouth mask that uses plural layer woven thing floor to make, and its outermost is the ventilative braid that one deck has multicolour pattern.Though such mouth mask can highlight the personal like or the taste of wearer, because of it does not possess the function that intercepts bacterium or virus, can't be used for the medical protection occasion, particularly can't use in the line medical applications of current anti-SARS.
For reaching the effect of sterilization, sterilization, general protective mask can press from both sides between nexine and outer shell fabric usually again establishes a functional layer that is exclusively used in filtration or sterilization.No. 02207820.7 Chinese patent provides a kind of multi-function health-care mouth mask, is provided with one in its cavity between the two-layer gauze layer in innner and outer and crosses filter core, and this is crossed filter core and comprises equal gas-bearing formation, active carbon layer and zeolite layer at least.This mouth mask is not only thick and heavy, dresses to get up can allow wearer feel ill easily, and after using at every turn, if will clean, all must remove cleaning with crossing filter core earlier, and the filter core excessively that will more renew, very inconvenient, also can additionally increase use cost simultaneously.
Similarly the mouth mask design also can be referring to Chinese patent No. 01264803.9, No. 01264442.0 and No. 01274331.3 Chinese patent, they also all are between precoats such as two-layer gauze in innner and outer or continuous cloth, increase the layer of a last tool filtering function again.What wherein, No. 01261803.9 Chinese patent adopted filters the filtering material layer that gauze and screen pack are formed by filter paper, medicine; No. 01264442.0 Chinese patent then is to use the gauze bag of adorning active carbon plate in one to realize its filtration; Chinese patent then is for No. 01274331.3 to adopt an internal layer that comprises the adsorption layer that is made of fiber and activated carbon granule at least, with reach its dedusting, remove peculiar smell, function such as disinfection.
That the mouth mask of above-mentioned prior art all exists to some extent is thick and heavy, dress shortcomings such as uncomfortable, and the wearer operating efficiency is reduced; And mostly can not directly clean, be not suitable for being repeatedly used.So not only cause waste, and increased in case of emergency, for example current nationwide resists, prevents under the situation of SARS, the difficulty of the medical protection distribution of materials.
Summary of the invention
The technical problems to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of medical protective mask with wet, blocking solution, fire-retardant, antistatic, dustproof, anti-virus functionality is provided.
Technical essential of the present utility model is: a kind of medical protective mask is provided, comprises mouth mask body and mouth mask fixture, this mouth mask body comprises nexine and skin; This mouth mask body further comprises the intermediate layer that a hydrophilic functional membrane constitutes, described nexine, intermediate layer and outer through the compound formation mouth mask body that becomes one.
Described outer adopt knitting, woven cotton or chemical fiber plus material through functional treatment, contain water repellent at least in it, also can contain antistatic additive and fire retardant.
The environmental protection hydrophilic functional membrane in described intermediate layer can adopt polyurethane polyethers film, thermoplastic polyurethane film (TPU), polyethylene film, polypropylene screen, pore type polyurethane film etc.
Described nexine adopts woven or knitting single face top-weight fabric that material chitin fiber with bacteria resistance function makes with fiber blends such as far infrared, cotton, spun silk, soybean respectively, mesh fabric etc.
Described mouth mask fixture comprises adjustable respirator belt and nose clip.Wherein, described nose clip is made by bent plastic material; Described respirator belt can adopt elasticity muscle band.This mouth mask body can be oval, square or other suitable shape.
The nexine of the mouth mask body of the utility model medical protective mask adopts the blended yarn weaved fabric of chitin fiber and other fiber, chitin fiber is a kind of natural polymer, nonpoisonous and tasteless, good biologically active, bio-compatibility and degradability are arranged, being used for weaving face fabric has well antibacterial, moisture absorption is ventilative, the effect of deodorization.Fibre and soya and spun silk have soft smooth, the good action that moisture absorption is wet thoroughly.
The film that adopt in the intermediate layer of mouth mask body is an environmental protection hydrophilic functional membrane, as polyurethane polyethers film, thermoplastic polyurethane film (TPU), polyethylene film, polypropylene screen, pore type polyurethane film.This base polymer presents semipermeability, and the relative humidity difference between skin surface and the air can be brought out this semi-permeable phenomenon; Also have hydrophilic radical on this polymer macromolecule simultaneously, also can with sweat gas that human body produced by hydrophilic radical be sent to the external world through absorption-diffusion-desorb, thereby have the wet thoroughly function of high-effective water-proof blocking solution.
And the outer shell fabric of mouth mask body is through functional treatment, have wet, the effect of blocking solution, fire-retardant, antistatic, dustproof, anti-virus.
The utility model is made by the lining that above-mentioned trilaminate material is composited, in the function that possesses wet, blocking solution, fire-retardant, antistatic, dustproof, anti-virus, dress advantages such as comfortable, frivolous but also have, and can repeated multiple times clean, have good durability.
