Problems solved by technology

When culturing cells with the above-mentioned prior art, along with the increase of cell density, it is difficult to achieve uniform distribution of cells, which will form a local cell-intensive area, affecting the transmission of the culture solution, and the concentration of the culture solution is uneven, which is not conducive to the normal growth of cells. The high cell density will also slow down the cell growth rate. The stirring method of the above-mentioned prior art has a large shear force, which will cause damage to the cells and is not conducive to the cultivation of the cells.

Abstract

The invention relates to a culture device for suspended tissue cells. The device includes a tissue cell culture body. The tissue cell culture body is a porous material. The porous material consists of pore cavities graded according to pore diameters and cavity walls forming the pore cavities in a surrounding manner. The cavity walls forming the upper-grade pore cavities in the surrounding manner are provided with lower-grade pore cavities. The pore cavities in each grade are communicated with each other, and the pore cavities of different grades are communicated with each other. The culture device also includes a cyclone apparatus disposed in the culture device. The culture device is particularly beneficial to free normal growth of suspended cells in a three-dimensional space. A cell over-dense zone or a nutrient enriched zone is not liable to be generated in a cell culturing process, cells are uniformly distributed and normal cell growth is facilitated.

Description

technical field [0001] The invention relates to a tissue cell culture device, in particular to a tissue cell culture device which is conducive to the free and normal growth of suspended cells in a culture solution under a culture environment. Background technique [0002] Cell culture refers to a culture technique in which cells are removed from tissues in the body, simulated in vivo environment, and grown and reproduced in vitro, and maintain their structure, function, and physiological characteristics under sterile, appropriate temperature, pH and certain nutritional conditions. . Cell culture can be divided into two categories: attached growth and suspension growth according to the characteristics of whether they can be attached to the support in the culture vessel. Adhesive cells can grow on the surface of the support during culture. Generally, fibers, microcarriers, porous materials, etc. can be used as culture media. Attached to the support to grow, when it is cultur...
