The invention provides a sterilization filter which comprises an upper shell, a lower shell and a transparent tube, a first connecting flange is arranged at an upper port of the lower shell, and a second connecting flange is arranged at a lower port of the upper shell; the transparent tube, the upper shell and the lower shell are of tubular structures, a third connecting flange and a fourth connecting flange are arranged at the upper end and the lower end of the transparent tube respectively, the upper shell is fixedly connected with the transparent tube through the second connecting flange and the third connecting flange, and the lower shell is fixedly connected with the transparent tube through the first connecting flange and the fourth connecting flange. An impurity filtering device and a degerming filtering device are sequentially arranged in the upper shell and the lower shell from bottom to top. The detachable connection of the upper shell and the lower shell is realized through the arrangement of the transparent pipe, and air can be filtered twice through the impurity filtering device and the degerming filtering device in the upper shell and the lower shell, so that the cost is reduced, and the filtering effect is improved.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to a sterilizing filter. Background technique [0002] The sterilizing filter mainly adopts a microfiltration filter element with a large specific surface area and a filtration accuracy of 0.22 μm or more. It is mainly used to prevent impurities in the air, harmful bacteria, and microorganisms from entering tanks, production lines, and sterile rooms, etc., causing water quality. Changes in products and clean room environment to meet the process needs of food, biochemical, beverage, beer, medicine, electronics and other industries. [0003] Existing inspection departments often need to carry out tests under sterile conditions, but the air contains dust, bacteria, etc., which cannot meet the requirements of sterility, so they often need to be treated with sterile filters to clean the The air is transported to the test equipment or the aseptic department, but the existing ...
