Description

Technical Field

[0001] The utility model belongs to the technical field of transfer covers, and particularly relates to a novel reagent transfer cover. Background Art

[0002] Sterile liquid storage bottles play a vital role in the biopharmaceutical industry. Every aspect of their design, manufacturing, and use must strictly comply with aseptic and biosafety standards. The cap of the sterile liquid storage bottle, as one of its core components, not only affects the sealing of the bottle and the purity of the liquid, but is also directly related to production efficiency and the final quality of the product.

[0003] For example, a Chinese patent with the announcement number CN221384381U discloses a liquid medicine transfer device, which relates to the field of liquid medicine transfer technology, including a bottle body, a reagent transfer cover body connected to the bottle mouth of the bottle body, an air drum with openings at both ends connected to the reagent transfer cover body, air filter membranes are fixed to both ends of the air drum through filter membrane pressure caps, the air drum is connected to a cap Luer for connecting with an external container during liquid transfer, and the air filter membrane is used to filter the air entering the air drum and discharge the gas in the air drum.

[0004] The transfer cover on the above-mentioned transferor fixes the air filter membrane to both ends of the air drum through the filter membrane pressure cap, which ensures the filtering effect of the air and avoids the problem of external bacteria entering the bottle body through the traditional filter and causing contamination. In the current design, the air filter membrane, as a key component, is directly welded to the air drum. While this integrated structure improves the structural stability, it also brings certain limitations. Specifically, as the usage time accumulates, the filtering efficiency of the air filter membrane will gradually weaken, affecting the overall filtering effect. The existing design architecture makes it extremely difficult to replace the air filter membrane individually, which undoubtedly increases the maintenance cost and time cost. Utility Model Content

Through the above arrangement, the convenience of maintenance work is improved. The operator can easily complete the replacement of the filter membrane without complicated tools or professional skills. At the same time, since the filter membrane can be replaced separately instead of replacing the entire air drum 3 as a whole, the maintenance cost is significantly reduced, and the overall service life of the transfer device is extended.

[0024] refer to Figure 1-2 The positioning assembly 11 includes a fixed disk 111, which is fixedly connected to one end of the pressure cover 4 close to the air filter membrane 5. One side of the fixed disk 111 is rotatably connected to a rotating block 112, one end of the rotating block 112 is fixedly connected to a first spring 113, and the end of the first spring 113 away from the rotating block 112 is fixedly connected to a fixed block 114. One end of the fixed block 114 is fixedly connected to one end of the anti-drop plate 10. An embedded groove 1111 is opened inside the fixed disk 111, and an embedded block 1121 is rotatably connected inside the embedded groove 1111. , one end of the embedded block 1121 is fixedly connected to one end of the rotating block 112; by setting the positioning assembly 11, the anti-slip plate is rotated, so that the fixed block 114 drives the rotating block 112 to rotate, and the rotating block 112 rotates on the fixed disk 111, and the position of the anti-slip plate is adjusted. Then, the air filter membrane 5 is attached to the pressure cover 4, and the anti-slip plate is pulled to deform the first spring 113. The anti-slip plate is rotated until it is located in front of the air filter membrane 5, and then the anti-slip plate is loosened, and the air filter membrane 5 is pressed on the pressure cover 4. This structure realizes the function of quickly disassembling and assembling the air filter membrane 5.

[0025] refer to Figure 1 and Figure 4 A socket 8 is provided inside the positioning block 6, and a plug rod 9 is fixedly connected to the inside of the air drum 3, and the plug rod 9 is movably connected to the socket 8; by providing a socket 8 in the positioning block 6, fixing the plug rod 9 in the air drum 3, and inserting the plug rod 9 into the socket 8, the position of the pressure cover 4 can be stabilized, preventing the pressure cover 4 from rotating and avoiding deviation in the installation position.

[0027] refer to Figure 4-5 The driving assembly 14 includes a mounting block 141, which is fixedly connected to both sides of the air drum 3. The mounting block 141 is slidably connected to a slider 142 inside the mounting block 141, and one end of the slider 142 is fixedly connected to one end of the connecting block 13.

The second spring 143 is set to enable the connecting block 13 to be connected and fixed to the connecting hole 12, so that the pressure cover 4 is fixed to the air drum 3.

[0028] refer to Figure 1 An isolation membrane 16 is attached to one side of the pressure cover 4, and the isolation membrane 16 is located on the outside of the air filter membrane 5; by providing the isolation membrane 16, when the transfer cover is not in use, it can prevent dust from entering the air drum 3 and adhering to the air filter cotton.

[0029] Principle and advantages of use: The reagent transfer cover body 1 is threadedly connected to the bottle body, the cover head Luer 2 is connected to the pipeline, and then the isolation membrane 16 is torn off, and air enters the air drum 3. Under the action of the air filter membrane 5 in the air drum 3, dust and bacteria in the air are filtered to prevent contamination in the bottle body. When the air filter membrane 5 needs to be replaced, the pull rod 144 is used to drive the slider 142 to move, and the slider 142 drives the connecting block 13 to move the connecting hole 12, so that the pressure cover 4 can be separated from the air drum 3, thereby removing the pressure cover 4, pulling the anti-slip plate to deform the first spring 113, so that the fixed block 114 drives the rotating block 112 to rotate, so that the rotating block 112 rotates in the disc, changing the position of the anti-slip plate so that the anti-slip plate no longer presses the air filter membrane 5, and then moving the air filter cotton to separate the positioning hole 7 from the positioning block 6, so that the air filter membrane 5 can be removed. Since the filter membrane can be replaced separately instead of replacing the entire air drum 3 as a whole, the maintenance cost is significantly reduced and the overall service life of the transfer device is extended.
