Description

A kind of antimicrobial nano medical mask

Technical field

The utility model relates to mask technical fields, more particularly to a kind of antimicrobial nano medical mask.

Background technique

At present in mask on the market, especially medical mask is almost made using several layers of non-woven fabrics or cotton gauze, this Class mask can be with stop portions dust, sundries, but does not play any, hospital environment complexity for the blocking of bacterial virus, Virus, bacterial species are various, easily infected during be easy to causeing cross-infection, medical staff to succour to patient.

Summary of the invention

Aiming at the shortcomings existing in the above problems, the utility model provides a kind of antibacterial medical mask, makes its filtering Good antimicrobial effect can effectively obstruct the invasion of the liquid such as dirt particle, alcohol, blood plasma, body fluid and bacterium, virus.

To solve the above-mentioned problems, the utility model provides a kind of antimicrobial nano medical mask, including cover, nose Folder, sponge strip and elastic ear band, the cover include hydrophobic skins, coarse filtration layer, antibacterial core nanoparticles filter layer and inside parent Skin layers.The hydrophobic skins, using hydrophobic polypropylene non-woven fabric.The coarse filtration layer is efficient electret polypropylene melt spraying, The particulate matter and liquid in air can tentatively be intercepted.The antibacterial core nanoparticles filter layer is to be prepared by electrospinning process Nanofiber.The inside skin-friendly layer, using the polypropylene non-woven fabric of soft pro-skin.The nose clip, using in external force Deformation and the metal strip of shape can be kept down.The sponge strip is made of special cut out of memory foam.The elastic ear band, Using flexible rubber or the stretch cord woven by terylene, spandex.The mask body will be several layers of by ultrasonic bonding Material is attached fixation, while two ear bands are fixed on mask body two sides.The sponge strip is by paste adhesive in mouth Cover body upper edge.

Further, the antibacterial core nanoparticles filter layer can effectively intercept the particles such as dust, bacterium, virus in air Object, can also effectively obstruct the liquid pollutants such as alcohol, blood plasma, and the antibacterial core nanoparticles filter layer is to pass through electrospinning process Preparation the nanofiber with antibacterial effect, the nanofiber with fiber finer, aperture is small, structure is fluffy, resistance is small, High-efficient equal filtering advantage, and the fiber has the effect of antibacterial, antibacterial.

Further, the nanofiber is dissolved in solvent by high molecular material addition antibacterial agent and is spun by high-pressure electrostatic What silk was prepared into, used high molecular material is POLYPROPYLENE GLYCOL, polystyrene, polyacrylonitrile, polycarbonate, polyester, polyamides Amine.Used antibacterial agent is triclosan, quaternary ammonium salt.Used solvent is tetrahydrofuran, n,N-Dimethylformamide, first Acid, acetic acid, acetone, water.

Further, the nose clip is prepared using metal strip, deformation and can keep shape under external force, be mask with Face is bonded closer.

Further, the sponge strip is made of special cut out of memory foam, and the memory foam has gas barrier Performance is good, the advantages that having sprung back.The memory foam is cut out by special, so that sponge can closely be attached to the wing of nose two Side can effectively obstruct exhalation hot and humid gas and leak out from bridge of the nose two sides gap, at the eyeglass for the doctor that wears glasses, cause water mist Layer, influences sight.

The utility model has the beneficial effects that

1, the utility model antimicrobial nano medical mask can effectively obstruct the particles such as dirt particle in air, bacterium, virus The liquid such as object and alcohol, blood plasma, body fluid.It prevents bacterial virus from entering human body by respiratory tract, guarantees that medical worker is working Sucking under environment is clean air.

2, the utility model antimicrobial nano medical mask, antibacterial core nanoparticles filter layer are added with antibacterial agent, can be effective Antibacterial, antibacterial, the cleanliness that guarantee passes through mask sucking gas.The antibacterial core nanoparticles filtering layer of the utility model have antibacterial, Fungistatic effect can effectively prevent breeding bacterium because air is damp and hot inside mask.

3, the utility model antimicrobial nano medical mask, sponge strip are that special cut out of memory foam is made, and have gas The memory foam of excellent in barrier property can be fitted tightly over wing of nose two sides, and effectively barrier exhalation hot and humid gas is leaked from bridge of the nose two sides gap Out, at the eyeglass for the doctor that wears glasses, water mist layer is caused, sight is influenced.
