Cell separation cup with high extraction purity

Abstract

The invention discloses a cell separation cup with high extraction purity. According to the technical scheme, the suction cup comprises a cup body, a cup cover, a suction pipe, a sterile pipe and a separation body arranged in the cup body, the separation body divides the interior of the cup body into an upper space and a lower space, and the top of the separation body is connected with the sterile pipe in a welded mode; the straw comprises a vertical section arranged outside the cup body and a bent section capable of penetrating through the wall of the cup body and the separation body to enter the lower space, and the bottom of the bent section is flush with the bottom of the separation body. According to the scheme provided by the invention, the suction tube can be prevented from damaging cells during centrifugation, residual cells in gaps are avoided, and the collection purity is improved.

Description

Technical field [0001] The present invention relates to the field of cell separation cups, and more particularly to a cell separation cup extracted from high purity. Background technique [0002] The structure of the prior art cell separation cup, such as patent No. US09118326B1, including cup, one separation body, and a suction tube, separating the interior space of the cup into a top and bottom, and the intake of the inner space through the cup Cup in the lower space. The problems of this structural solution in the actual use are: 1, the straw penetrates the separation cup from the top, since the liquid is contacted with the straw, a large tangent force is generated when centrifugation, and the cell damage is very Large; 2, there is a gap between the straw and the inner wall, still have many cells remain in the gap after centrifugation, affecting the purity of cell extraction; And due to this type of winding, the length of the sterile tube cannot be too long, thereby reducing t...

AI Technical Summary

Problems solved by technology

The problems in the actual use of the cell separation cup with this structural scheme are as follows: 1. The straw runs through the separation cup from the top downward. Since the liquid contacts the straw, a large tangential force will be generated during centrifugation, which will greatly damage the cells. Large; 2. There is a gap between the straw and the inner wall, and many cells will remain in the gap after centrifugation, which will affect the purity of cell extraction; 3. The original aseptic tubing is not tightly wound, and it is easy to come out and shake during centrifugation. And because of this winding method, the length of the sterile tube cannot be too long, so the number of times of use of the separation cup will be reduced; 4. The original technology uses the C-shaped tube clip as a handle to take and place the separation cup, but due to the slippery surface of the material , the separation cup is heavy when fully loaded, even with anti-slip texture, it is still easy to slip off
