Tester for bacteria blocking property of gas permeable packing material in aseptic apparatus

The utility model relates to a tester for the bacteria blocking property of gas permeable packing material in an aseptic apparatus, and belongs to the field of medical experimental installations. The tester is characterized by comprising a cabinet body, and an aerosol generation system, a test box, a sample clamping system, an attraction system and an integrated control system that are positioned in the cabinet body. In the tester, aerosol is generated in the principle of compressed air atomizing, is blown in the test box, and is then blended by an agitation fan; bacterium aerosol is pumped into each group of samples by a vacuum pump; each sample is individually equipped with a flow controller to ensure the flow rate of bacterium aerosol flowing through each group of samples, namely the amount of bacteria in each group of samples is ensured; and the amount of the bacteria on filter paper on each group of samples is measured to determine the penetrability of gas permeable packing material blocking bacteria. The bacteria blocking property of gas permeable packing material in the aseptic apparatus can be quickly and accurately tested.
