Description

Technical Field

[0001] This utility model relates to the field of cell screening tube technology, and in particular to an easily extractable cell screening tube. Background Technology

[0002] Publication No. CN220597467U discloses a cell screening tube, including a screening tube body with a liquid inlet at the top, a separation cap at one end, and a liquid-pressing device at the other end. During screening, the liquid-pressing device presses the cell mixture towards the separation cap. A fixed cap and the screening cap are rotatably connected. A flange is fixedly provided on one end of the screening cap near the screening tube body. A plurality of screening holes are evenly distributed circumferentially on the sidewall of the screening cap, and a screening membrane is fixedly provided in each screening hole. A liquid outlet is provided on the sidewall of the fixed cap to cooperate with the screening holes. The liquid-pressing device presses the cell mixture towards the separation end. Different filter membranes are provided in different screening holes. The rotating filter cap allows for precise alignment of the filter holes with the liquid outlet, facilitating targeted extraction of cell mixtures. This means that different types of cells can be extracted using a single liquid outlet. Traditional cell filter tubes require cumbersome disassembly and assembly when different pore sizes are needed, consuming significant time and potentially leading to errors that compromise screening quality. This inflexibility in handling diverse experimental needs is a clear disadvantage in dynamic experimental environments, significantly reducing the device's adaptability and ease of use, increasing complexity and time costs, and lowering overall efficiency. Improvements are needed. Utility Model Content

The water inlet 5 on the shell 1 facilitates the addition of liquid, while the mounting block 7 sliding inside the rotating ring 6 fixes the filter plate 8, facilitating adjustment or replacement of the filter plate 8. The limiting rod 9 and spring 11 inside the mounting block 7 work together with the push plate 103 to ensure the rapid and accurate positioning and fixing of the filter plate 8, optimizing the adjustability and speed of the screening process. A discharge port is provided at the connection between the outer shell 1 and the rotating ring 6. The rotating ring 6 and the outer shell 1 are rotatably connected by a bearing. The filter plate 8 can be aligned with the position of the discharge port. The use of bearings ensures the smooth rotation of the rotating ring 6, improving the operational flexibility and material handling efficiency of the equipment. There are six sets of mounting blocks 7, and each set of mounting blocks 7 is equipped with a filter plate 8. The filter plates 8 with different pore sizes can be used to screen different situations as needed. The limiting rod 9 is slidably connected to the rotating ring 6, and one end of the spring 11 is fixedly connected to the mounting block 7. The spring 11 can make the limiting rod 9 slide from the inside of the mounting block 7 to the inside of the rotating ring 6, so that the mounting block 7 can be quickly replaced.
