Micro-negative pressure cell culture device

Abstract

The invention relates to the technical field of cell culture, and discloses a micro-negative pressure cell culture device. The cell culture device comprises a culture dish tank; a feeding port is formed in the top end of the culture dish tank; an adjusting assembly is movably connected to the top end of the culture dish tank; and an automatic lifting supporting rod is fixedly mounted on the outer wall of the bottom of the culture dish tank. According to the micro-negative pressure cell culture device, cells to be cultured fall into the inner wall of the culture tank along a smooth trapezoidal table from the feeding port, and a culture solution is placed on the inner wall of the culture tank, so that cell development is carried out; after culture for a period of time, the negative-pressure environment can be destroyed; at the moment, under the condition that the temperature is unchanged, the negative pressure environment is kept by changing the volume; and while carbon dioxide is generated, the automatic lifting supporting rod moves upwards and drives a dial to move upwards, so that the volume can be increased, the stability of micro-negative pressure is guaranteed, and rapid cell development and the accuracy of experimental data are guaranteed.

Description

technical field [0001] The invention relates to the technical field of cell culture, in particular to a micro negative pressure cell culture device. Background technique [0002] Negative pressure wound treatment technology is a new technology developed in medicine in recent years to treat wounds. It uses biological semipermeable membranes to promote the closure of open wounds, and then generates a certain negative pressure through a special negative pressure machine, and drains the drainage tube. And the dressing acts on the wound after debridement. According to relevant medical research, this therapy can accelerate the blood circulation of the wound, significantly promote the entry of new blood vessels into the wound, stimulate the growth of granulation tissue, fully drain, reduce edema, and reduce pollution. , Inhibit the growth of bacteria, and can directly accelerate wound healing, creating conditions for surgical repair. [0003] In the development of this new technol...

Problems solved by technology

[0003] In the development of this new technology, it is necessary to create a specific negative pressure environment for the cultured cells to make the cells grow faster, but in the existing technology, the cells are developed by maintaining the negative pressure environment of the cells. After a long period of cultivation, the gas will leak, and it is more complicated to create a new negative pressure environment, and the procedures are cumbersome. The instability of the negative pressure environment will lead to incomplete cell development, and the more serious result is cell necrosis. For the above Question, we proposed a micro-negative pressure cell culture device, by ensuring the negative pressure environment to ensure the stability of negative pressure, ensure the rapid development of cells, and ensure the accuracy of experimental data
