Abstract
A novel dust-gas mask is composed of the convex main body with holes and aerating valve, ear bands, fixing hooks, filter material, external fixing cover. Its advantages are high effect to prevent dust and toxic air, and high practicality.
Description
Technical field:
The invention belongs to medical protection articles for use field, it relates to a kind of novel antidusting and anti-poisoning mask.
Background technology:
Mouth mask is dustproof as mouth, nose organ, the gas defence device has obtained extensive use, but existing mask material and manufacturing process make mouth mask dustproof, the gas defence effect is not satisfactory, as the extremely strong SARS virus of infectiousness, because of problems such as the material of mouth mask and the sealing worn are relatively poor, make that the probability of the doctor that fights bravely at anti-SARS one line, infection in nurses SARS is very high.
Summary of the invention:
According to defective in measure of present protection virus spread or the product and deficiency, the invention provides a kind of novel antidusting and anti-poisoning mask.
The technical scheme of technical solution problem of the present invention is as follows:
A kind of novel antidusting and anti-poisoning mask, it is characterized in that it comprises that left end links to each other with soft sealing ring 7 with holes, right-hand member both linked to each other with fixed cover 6 in the detachable filtering material with holes, the convex mask 1 of the band charge valve with holes of overcoat stay hook 3 with holes again, entangle the stay hook with holes 3 on the convex mask 1 of band charge valve with holes firm, left side inner face links to each other with the convex mask 1 of band charge valve with holes, the right side links to each other with filtering material 4, fixed cover 6 in the detachable filtering material with holes that the outer fixed cover 5 of upper right end face and detachable filtering material with holes links to each other, inner face both linked to each other with fixed cover 6 in the detachable filtering material with holes, the outer fixed cover 5 of the detachable filtering material with holes that links to each other with filtering material 4 again, both linked to each other, again the filtering material 4 that links to each other with the outer fixed cover 5 of detachable filtering material with holes with fixed cover 6 in the detachable filtering material with holes, the attaching lug band 2 that links to each other with stay hook 3 with holes, the with holes soft sealing ring 7 that the right side links to each other with the convex mask 1 of band charge valve with holes;
The shape of convex mask 1 right part of described band charge valve with holes can change makes hook type or triplet type;
The material of the convex mask 1 of described band charge valve with holes and the inside and outside fixed cover 5,6 of detachable filtering material with holes can adopt engineering plastics (ABS), polyvinyl chloride (PVC), acrylic (PMMA) material; On the described stay hook with holes 3 4～6 pawls can be arranged, material can adopt common plastics to make; The inner layer material 41 of described filtering material 4 can adopt gauze, and layer material 42 can adopt active carbon fiber felt or gauze in the left side, and layer material 43 can adopt the high efficiency filter material in the right side, and as superfine polypropylene nonwoven or gauze, cladding material 44 can adopt refuses water liquid repellent lining; Described soft sealing ring 7 materials with holes can be rubber, polyamine fat elastomer.
Advantage compared with prior art of the present invention is:
Novel antidusting and anti-poisoning mask of the present invention has good dust proof and gas defence safeguard function and serviceability, and this mouth mask cost is low, in light weight, easily manufactured, safe and reliable.
