Bacteria resisting tester of sterile device air permeability packing material

The invention relates to a bacteria resisting tester of a sterile device air permeability packing material, belonging to the field of experimental equipment used for medical treatment. The tester is characterized by comprising a cabinet, an aerosol generation system in the cabinet, a test chamber, a sample clamp system, an attraction system and an integrated control system; the aerosol is generated by utilizing a compressed air spray principle by the tester, the aerosol is blown into the test chamber, and is mixed by utilizing a stirring fan; the bacterial aerosol is extracted into each groupof samples by utilizing a vacuum pump; each sample is independently provided with a flow controller; the flow flowing each group of samples is ensured, namely the bacterium challenge quantity of eachgroup of samples is ensured; the penetrability of the microorganism resisted by the permeability packing material is determined through detecting the bacterial quantity on the filter paper of each group of samples, and the bacteria resisting properties of the sterile device air permeability packing material can be rapidly and accurately tested.
