Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical production technology, and in particular to a filtration device for pharmaceutical production. Background Technology

[0002] Drug research and production both require cell culture to obtain effective substances. Cell culture technology has stringent process requirements, primarily differing from general laboratory work in its requirement for complete aseptic technique to prevent the influence of microorganisms and other harmful external factors. Preventing contamination is crucial to the success of cell culture. Even in well-equipped laboratories, carelessness and improper operation can lead to contamination. Therefore, all operations must be performed with the utmost care to ensure sterility. Furthermore, cell culture technology requires sterile equipment, and gas sterilization filters, as effective sterilization devices, require extensive quality control to guarantee high-efficiency sterilization. Existing sterilization filters currently have low efficiency, and their filter cartridges are difficult to replace.

[0003] A search revealed Chinese Patent Publication No. CN208626800U, which discloses a filtration device for pharmaceutical equipment. The device includes a filter box with an inlet at the top and a filter screen inside. A high-pressure air pump is located at the bottom right side of the filter box. The bottom of the filter box is connected to the top of a base. A motor is located inside the base, and a rotating shaft is located at the top of the motor. A filter box is fixedly connected to the top of the rotating shaft. This invention is reasonably designed and solves the problem that many impurities are mixed into the drugs during the pharmaceutical process. Currently used filtration devices cannot accurately remove these impurities, leading to potential harm to the human body from the use of such drugs. It has high practical value. However, this device has low gas filtration efficiency and poor performance, easily causing cell culture failure. Utility Model Content

The inlet pipe is located in the middle of filter screen one and filter screen two. When the gas passes through filter screen one and filter screen two, microorganisms are trapped, and clean gas is discharged from the outlet. The top cover seals the outer shell, and the sealing element presses the structural frame to achieve complete isolation. No gas will pass through the gaps, achieving complete filtration, improving the filtration efficiency of the sterilization filter, and ensuring a sterile environment during cell culture.

[0030] 2. In this utility model, when it is necessary to replace filter screen one and filter screen two, first open the buckle, and then pull the two buttons simultaneously. The buttons are connected to the fixed post through the connecting post and the rotating sleeve. When the button is pulled, the spring is compressed and the locking block slides, so that the locking block disengages from the slot and the top cover can be removed for easy replacement. After replacement, align the fixed plate with the hole in the middle of the locking sleeve and insert it. The locking block is locked into the slot under the action of the spring. Then, tighten the buckle and hook to complete the locking. This simplifies the filter replacement process and reduces the difficulty of operation and the risk of contamination.
