Abstract
The utility model discloses a gas filter for the respiratory device, including the shell body 1, air inlet 2 set in the shell body 1 and air outlet 3. From the side of the air inlet 2 in the shell body are the disinfection and filter layer 4, active carbon adsorption layer 5 and Millipore filtration layer 6, which are separated by the pored partition board 7; the disinfection and filtration layer 4 is made of filter gauze with adsorbed disinfection agent. This utility model has the advantages of through filtration and supplementary disinfection function.
Description
Technical field
The utility model relates to the breathing apparatus pneumatic filter that epidemic victims such as a kind of medical ventilator systems gas-filtering device, particularly a kind of pulmonary tuberculosis use.
Background technology
The prior art pneumatic filter adopts the single layer filter mode more, filter effect is bad, and filter itself do not have the function of virus killing, and microbe granular is just by the absorption of machinery or be isolated in the filter, also can growth and breeding under the temperature that is fit to, cause secondary pollution easily.
Summary of the invention
The purpose of this utility model is to provide a kind of and overcomes above-mentioned shortcoming, filters thoroughly, has concurrently the breathing apparatus pneumatic filter of virus killing function.
The utility model is achieved in that a kind of breathing apparatus pneumatic filter, comprise housing and the air inlet, the gas outlet that place on the housing, set gradually virus killing filter course, activated carbon adsorption layer and micro porous filtration layer from air inlet side in this housing, separated by dividing plate with holes between the three, the virus killing filter course is made of the filter screen that is adsorbed with disinfectant.
The utlity model has three layer filtration, filter effect is more thorough, and has the virus killing filter course, and the energy killing pathogenic bacteria has effectively been avoided the generation of secondary pollution phenomenon in filtering microorganism.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
Accompanying drawing is the utility model cross-sectional schematic.
The specific embodiment
As shown in the figure, the utility model comprises housing 1 and the air inlet 2, the gas outlet 3 that place on the housing 1, set gradually virus killing filter course 4, activated carbon adsorption layer 5 and micro porous filtration layer 6 from air inlet 2 sides in the housing 1, separate by dividing plate with holes 7 between the three, virus killing filter course 4 is made of the filter screen that is adsorbed with disinfectant, and micro porous filtration layer 6 can adopt multi-layer microporous filter paper to make.During use, air inlet 2, gas outlet 3 connect air inlet pipe and escape pipe respectively, the gas of patient respiration is at first through virus killing filter course 4, the disinfectant that germ major part in the gas is attracted in the virus killing filter course 4 kills, after passing through activated carbon adsorption layer 5 and micro porous filtration layer 6 again, gas is purified, and can directly discharge.
Claims (1)
1, a kind of breathing apparatus pneumatic filter, comprise housing and the air inlet, the gas outlet that place on the housing, it is characterized in that: set gradually virus killing filter course (4), activated carbon adsorption layer (5) and micro porous filtration layer (6) from air inlet (2) side in this housing (1), separated by dividing plate with holes (7) between the three, virus killing filter course (4) is made of the filter screen that is adsorbed with disinfectant.
