Description
Technical field
The utility model relates to a kind of medicine and industrial hygiene equipment, particularly relates to a kind of device of testing disposable mouth mask performance.
Background technology
Existing human body is broadly divided into two big classes with disposable mouth mask performance test apparatus by filter medium: with the disposable mouth mask test board of the most difficult filtration size particles thing test and the disposable mouth mask test board of testing with industrial dust.The disposable mouth mask test board of the most difficult comparatively general in the world filtration size particles thing test is the 8130 type automatic filter test boards that U.S. Technical Sourcing Internation produces; adopting near sodium chloride (NaCl) particle of 0.075 micron size or near 0.185 micron phthalic ester (DOP) particle of size is filter medium test mouth mask filter effect; the pressure that the mass concentration of using two cover granule density counters to note down mouth mask front and back filtration media granules thing at one time is worth gentle stream process falls, thereby obtains filtration efficiency and gas-flow resistance.It is tested media that the sodium salt method of CNS regulation adopts 0.02 μ m～2 μ m sodium salts, the pressure that the same mass concentration of using two cover granule density counters to note down mouth mask front and back filtration media granules thing at one time is worth gentle stream process falls, and obtains filtration efficiency and gas-flow resistance.It is tested media that the soot technique of CNS regulation adopts multiple particle diameter medical talc powder, uses filter membrane to gather the filtration efficiency of the method calculating mouth mask that talcum powder is weighed then in the air of mouth mask front and back.Above test board is provided with the equipment of special generation particle, and the tested media particle concentration is changed in a small range, has stablized test result to a certain extent.
It is filter medium that these several disposable mouth mask testing apparatuss all can not detect with the environment gasoloid, the filter effect when mouth mask is worn on the headform.And in actual use, a large amount of disposable mouth masks are used in the atmospheric environment or by medical personnel by the general population and are used in the hospital environment, because lacking reflection environment gasoloid (environment aerosol particle thing PM10, PM2.5 and the PM1.0 of national Specification monitoring) is the mask filtration efficiency test board of filter medium, therefore can't provide comparatively accurately suitable guidance for the use of mouth mask in the atmospheric environment.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of device of testing disposable mouth mask performance, to remedy the deficiencies in the prior art or defective, satisfies the needs of life and medical and health.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of device of testing disposable mouth mask performance, comprise standard silica gel headform 2 and dust detector 7, disposable mouth mask 1 is positioned at standard silica gel headform 2 mouth and nose position, rigid plastic conduit 3 embeds standard silica gel headform 2 inside, the lower end at nostril place and with snout downside plane parallel, stretch out from hindbrain the upper end, standard silica gel headform 2 links to each other with an end of plexi-glass tubular 4 by rigid plastic conduit 3, the other end of plexi-glass tubular 4 links to each other with vacuum pump 6 by rigid plastic conduit 3, is provided with flowmeter 5 between plexi-glass tubular 4 and vacuum pump 6; Plexi-glass tubular 4 links to each other with pressure gauge 8 with dust detector 7 respectively by soft conduit 9.
As optimized technical scheme: described flowmeter 5 is a ball float flowmeter; Described dust detector 7 is a TSI dust detector; Described pressure gauge 8 is a digital pressure gauge.
The utility model is work like this: use TSI dust detector to record variable grain diameter gasoloid (PM10 in the surrounding air, PM2.5 and PM1.0) after the mass concentration, the disposable mouth mask of surrounding air through needing on the headform who is worn on the CNS regulation to test, enter place, the silica gel headform nostril rigid plastic conduit suitable with the aperture, nostril, to enter diameter be in the plexi-glass tubular about 500mm by embedding silica gel headform rigid plastic conduit again, reuse TSI dust detector and record variable grain diameter gasoloid (PM10 in the organic glass inner air tube, PM2.5 and PM1.0) mass concentration and use digital pressure gauge record air-flow from before the mouth mask in plexi-glass tubular the time pressure that produces fall, then airflow through with the suitable rigid plastic conduit in aperture, nostril after, enter ball float flowmeter, be discharged to outdoor by the vacuum pump extraction at last.
Principle of work of the present utility model is: when the disposable mouth mask is worn on normal man's head model, under the negative pressure of bleeding of vacuum pump, making the surrounding air air communication cross number of people nostril place conduit enters one and can make the uniform and stable diameter of air-flow at 50mm left and right sides plexi-glass tubular, the adjusting that re-uses ball float flowmeter makes air draught form different flow, stable, air-flow when the simulation human body is air-breathing, variable grain diameter environment gasoloid (PM10 in the plexi-glass tubular before when each steady air flow flow, adopting two cover TSI dust detectors to test mouth mask respectively simultaneously and behind the mouth mask, PM2.5 and PM1.0) mass concentration, meanwhile adopt digital pressure gauge to record air communication and cross mouth mask, model number of people nostril, formed pressure falls behind hard conduit and the plexi-glass tubular front end.
Calculate before the mouth mask and the ratio of the environment aerosol quality and concentration value that two cover TSI dust detectors record behind the mouth mask, the variable grain diameter environment gasoloid penetrance in the time of can obtaining mouth mask and be worn on normal man's head model, establishing P is penetrance:
Interior environment gasoloid (PM10, PM2.5 or the PM1.0) mass concentration of plexi-glass tubular behind environment gasoloid (PM10, PM2.5 or PM1.0) mass concentration/mouth mask before the P=mouth mask
Be worn at mouth mask under this air flow rate then that the filtration efficiency η to environment gasoloid (PM10, PM2.5 or PM1.0) is on normal man's head model:
η＝(1-P)×100
And simulation human body inspiratory resistance just equals under this air flow rate, mouth mask is worn on normal man's head model, during at environment gasoloid (PM10, PM2.5 or PM1.0), formed pressure fell after air communication was crossed mouth mask, model number of people nostril, hard conduit and plexi-glass tubular front end.
The beneficial effects of the utility model are: reasonably adopted novel test instrument and new assembled scheme, can test in the short period of time and filter aerocolloidal filter effect of environment and gas-flow resistance when the disposable mouth mask is worn on the headform, and can provide PM10, PM2.5 and PM1.0 filter effect data, be complementary with particle concentration boundary value in the surrounding air of country monitoring, comparatively accurately suitable help for the general population uses the disposable mouth mask to provide in atmospheric environment can also provide comparatively believable reference for medical personnel use the disposable mouth mask in hospital environment simultaneously.
