Abstract

The utility model relates to an efficient medical protective mask, comprising a mask face body and a fastening belt, wherein the face body comprises an inner layer, a middle layer and an outer layer; wherein the inner layer is made of common health gauzes or non-woven fabrics; the middle layer is made of superfine polypropylene fiber melt-blown materials and the outer layer is made of non-woven fabrics or superfine polypropylene fiber melt-blown materials. The efficient medical protective mask has strong hydrophobicity and permeability with significant filtering results, and the overall filter rate for micro gas sols or harmful fine dusts is up to 99%. The poisonless and harmless materials are adopted, therefore the utility model is comfortable for wearing.

Description

The efficient medical protective mask

Technical field

The utility model relates to a kind of mouth mask.

Background technology

Mouth mask is modal a kind of protective respirator in the daily life, and main effect is to prevent the direct suction of dust or bacterium, virus, protection face and respiratory system.Now more common mouth mask has common gauze or non-woven fabrics gauze mask, active carbon interlayer mouth mask, or some other mouth mask that has the medicine interlayer.The outstanding defective of these mouth masks is exactly the contradiction that all exists between filterability and the gas permeability, with common cotton cloth respirator is example, for strengthening filterability, will increase the number of plies (as using the gauze more than 16 layers) of gauze, so just greatly reduce the gas permeability of mouth mask, wear the shortage comfort.

Summary of the invention

The purpose of this utility model is to provide a kind of filter efficiency height, gas permeability strong, and wears comfortable efficient medical protective mask.

The technical solution of the utility model is as follows: the efficient medical protective mask is made up of mouth mask face body and puller strap, wherein mouth mask face body be divided into interior, in, outer three layers, internal layer is common health gauze or nonwoven, the middle level is a superfine polypropylene fiber melt-blowing material layer, and skin is nonwoven or ultra-thin polypropylene melt-blown material layer.

Aforesaid efficient medical protective mask, the thickness of its mouth mask face body middle level superfine polypropylene fiber melt-blowing material layer is 1～6mm, the thickness of outer ultra-thin polypropylene melt-blown material layer is 0.05～0.5mm.

This efficient medical protective mask hydrophobic, air-permeability is strong, and remarkable to the filter effect of the small colloidal sol of poison gas in spite of illness or harmful micronic dust, the overall filtration effect reaches more than 99%, and material therefor is nontoxic, wears comfortable.

The specific embodiment

The efficient medical protective mask is made up of mouth mask face body 1 and puller strap 2 two parts.As shown in Figure 1, that mouth mask face body 1 is divided into is interior, in, outer three layers, internal layer is common health gauze or nonwoven 3; The middle level is a superfine polypropylene fiber melt-blowing material layer 4, and its thickness is 1～6mm, generally can select 1mm, 3mm, 5mm, 6mm for use; Skin is nonwoven or ultra-thin polypropylene melt-blown material layer 5, and its thickness is 0.05～0.5mm, generally can select 0.05mm, 0.1mm, 0.3mm, 0.5mm for use.Adopt the mode of hot pressing or stitching to fit together between layer and the layer.

As shown in Figure 2, mouth mask face body 1 layers of material size can be selected 170mm * 170mm, laterally processes corrugated surface, and the rectangular surfaces body that final shape is grown into 170mm, the wide 80～100mm of being is fixed a puller strap 2 respectively for four jiaos of the face body.

In addition, as shown in Figure 3 and Figure 4, mouth mask face body 1 also can be processed into circle or half elliptic, mouth mask face body 1 each symmetry of both sides be provided with one or two puller straps 2, below mouth mask face body 1, be provided with two puller straps 2.When wearing mouth mask, the mouth mask lower edge can be entangled lower jaw, two puller straps of mouth mask below are fastened, strengthen the driving fit effect of mouth mask.

The place is sewed with a nose clip 6 that is made of the soft metal sheet in the middle of the top of mouth mask face body 1 middle level superfine polypropylene fiber melt-blowing material layer 4, and the length of this sheet metal is greater than 85mm, and width is 2～8mm, thick 1～3mm.When wearing mouth mask, the sheet metal that press...withes one's finger is buckled on the bridge of the nose sheet deformation, plays the driving fit effect of mouth mask nose.

Superfine polypropylene fiber melt-blowing material that adopt in the middle level of mouth mask face body and the outer ultra-thin polypropylene melt-blown material that is adopted are well known materials, the permanent development in science and technology of safe good fortune Co., Ltd produces by Beijing, the efficient medical protective mask resistance that uses this material to make can reach 6.86Pa, and filter efficiency can reach 99.9%.
