The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1-3, the medical protective nose mask comprises a nose mask body 1, wherein the nose mask body 1 is in a strip shape, and can cover the nose and cheeks at two sides of the nose to achieve a protective effect. Be connected with elasticity ear area 2 on nose cup body 1, in order to be adapted to different personnel's the demand of wearing, nose cup body 1's middle part top is equipped with the bellied arc structure that makes progress, arc structure department is equipped with protects nasal part 10, protect nasal part 10 and accord with the structure of people's nose, can cover the nose completely, it extends to 2cm departments from nose cup body 1 bottom downwards to protect nasal part 10 from arc structure top, the distance between nasal part 10 bottom and the nose cup body 1 bottom is selected according to the nose cup of not equidimension specification of difference, minimum not less than 1cm, in order to guarantee the protection to last lip department, it is generally between 1-3cm to protect the distance between nasal part 10 bottom and the nose cup body 1 bottom, it is best to cover last lip completely, make this nose cup can not produce gas leakage in last lip department, play the guard action when having a dinner to the user.
The nose mask body 1 is formed by sewing an outer fabric layer 4, a filter layer and an inner fabric layer 5 which have the same structure, and the filter layer comprises a water-soluble film layer 6, an antibacterial textile fabric layer 7, a fluorine-containing fiber microporous film layer 8 and a water-absorbent resin layer 9 which are sequentially arranged from the outer fabric layer 4 to the inner fabric layer 5. The water-soluble film layer 6 is mainly used for forming a moisturizing layer on the antibacterial textile fabric layer 7, the antibacterial textile fabric layer is a nano-zinc oxide antibacterial real silk fabric, or a modal and tencel blended nano-silver antibacterial fabric, and the antibacterial textile fabric layer 7 has certain filtering capacity and can sterilize bacteria adsorbed on the moisturizing layer; the fluorine-containing fiber microporous membrane layer 8 is used for filtering viruses and other pollutants, and the water-absorbent resin layer 9 is used for absorbing water drops generated by accumulation on the inner fabric layer 5, so that the comfort of the nasal mask is guaranteed.
The water-soluble film layer 6 is a polyvinyl alcohol film with the thickness of 0.04mm, the water-soluble film layer 6 cannot be thick, otherwise, the water-soluble film layer is difficult to dissolve in a short time, the nose mask is difficult to use, the water-soluble film cannot be thin, otherwise, a moisture-retaining layer cannot be formed, and the water-soluble film can be replaced by one of a carboxymethyl cellulose film, a hydroxyethyl cellulose film or a solidified cellulose film; the water absorption resin layer 9 is made of polyethylene resin with the thickness of 0.2mm and containing starch grafted acrylate polymerization cross-linked polymer, a plurality of through holes are formed in the water absorption resin layer 9, the aperture of each through hole is 3mm, and the aperture is selected on the basis that the nose mask does not obstruct breathing when in use; the fluorine-containing fiber microporous membrane layer 8 is composed of polytetrafluoroethylene fibers with the diameter of 600nm, and other fluorine-containing fiber microporous membranes can be used instead, such as a microporous membrane composed of polyvinylidene fluoride fibers with the diameter of 400nm, and a microporous membrane composed of polytetrafluoroethylene fibers with the diameter of 800nm and polyvinylidene fluoride fibers with the diameter of 500 nm; wherein the thickness of the fluorine-containing fiber microporous membrane layer 8 is 0.3mm, and the aperture of the fluorine-containing fiber microporous membrane layer 8 is 300 nm; the outer fabric layer 4 is a waterproof and oil-proof breathable textile fabric with the thickness of 0.6mm, so that oil stains and water cannot be adhered to the nose mask when the nose mask is used, and the inner fabric layer is a skin-friendly fabric with the thickness of 1.0mm, so that the use comfort is enhanced.
When the medical protective nose mask is used, after a user wears the medical protective nose mask, water vapor exhaled by the nasal cavity passes through the inner fabric layer 5, the through holes on the water absorbing resin layer 9 and the fluorine fiber microporous membrane layer, so that the water soluble membrane on the filter layer is dissolved by the water vapor, a part of the water vapor is intercepted by the filter layer to form a moisture retention layer, the outer fabric layer 4 is a waterproof and oilproof breathable textile fabric, so that the moisture retention layer can only be adhered to the antibacterial textile fabric layer 7, the pollutants and viruses in the air passing through the outer fabric layer 4 are trapped by the adsorption action of the moisture-preserving layer and the antibacterial textile fabric layer 7, most of the pollutants and viruses can be killed by the antibacterial textile fabric layer 7, thereby the pressure that makes the fluorine-containing fiber micropore rete 8 filter virus and pollutant diminishes, makes the fluorine-containing fiber micropore rete 8 can filter pollutant and virus thoroughly to make this nose cup have stronger filter capacity. The nose mask has the filtering efficiency of 99.8 percent according to the test method in GB19083-2003 technical requirements for medical protective masks. In addition, the filtration efficiencies of the nasal mask after the water-soluble membrane layer 6 and the antibacterial textile fabric layer 7 were sequentially removed were 97.3% and 86.5%, respectively, by blank comparison.
In addition, the upper portion of arc structure is equipped with bar metal nose clip 3 to guarantee that different personnel can adjust the laminating compactness of nose cup body 1 and facial when using.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
