Embodiment Construction

[0018] A cell separation filter, see figure 1 : It includes a first inner layer 1 and a second outer layer 2 formed around the cloth, the center of the first inner layer 1 forms a filter element cavity 3, the first inner layer 1 is specifically formed by sintering a relatively high percentage of hydrophilic groups, and the second outer layer The layer 2 is specifically formed by sintering a relatively low percentage of hydrophilic groups, and the second outer layer 2 covers the outer wall of the first inner layer 1 .

[0019] The first inner layer 1 is specifically formed by sintering 2% hydrophilic groups, and the second outer layer 2 is specifically formed by sintering 1% hydrophilic groups;

[0020] The axial lengths of the first inner layer 1 and the second outer layer 2 are the same, and the axially outer end surfaces of the first inner layer 1 and the second outer layer 2 are arranged flush;

[0021] In a specific embodiment, the first inner layer 1 is an annular struct...

Abstract

The invention provides a cell separation filter element, which effectively improves the separation of cell carriers and solutions, prevents cells from being polluted by any bacteria, and saves separation time, and the cells are made into cell smears for detection. Can be used for high-precision research. It includes a first inner layer and a second outer layer formed around the cloth. The center of the first inner layer forms a filter core cavity. The first inner layer is specifically formed by sintering a relatively high percentage of hydrophilic groups. The second outer layer Specifically, the layer is formed by sintering with a relatively low percentage of hydrophilic groups, and the second outer layer covers the outer wall of the first inner layer.

Description

technical field [0001] The invention relates to the technical field of separation filter elements, in particular to a cell separation filter element, and the invention also provides a manufacturing method of the cell separation filter element. Background technique [0002] Cell detection technology is widely used in medical and health, biomedicine and other fields. At present, the widely used technology is that the cell centrifuge uses the centrifugal force of the rotating motion to precipitate the suspended micro-particles, so that the solution can be separated, and then used in a filter centrifuge. Separating the suspension, when the drum rotates, the liquid in the suspension is thrown out of the drum through the filter screen and the small holes on the drum wall under the action of centrifugal force, while the solid phase is trapped on the filter screen to form a filter residue layer. The filter residue can be unloaded manually after the drum stops, and the obtained cells...
