Abstract

The invention relates to the technical field of biological cell extraction, and discloses a biological stem cell rapid separation and extraction device based on a centrifugal force effect. The biological stem cell rapid separation and extraction device comprises a base, the upper end of the base is fixedly provided with a fixing frame, and the interior of the fixing frame is rotationally connected with a separation device. According to the biological stem cell rapid separation and extraction device based on the centrifugal force effect, separation liquid is put into a separation device, then the separation device rotates in the fixing frame, in the rotation process of the separation device, due to the existence of the centrifugal force, an arc-shaped plate can be driven to slide in a fixing ring, and then under the effect of a connecting spring, the extension length of the arc-shaped plate can be continuously changed, so that a stirring rod can be driven to move together, and the effect of fully stirring the separation liquid is achieved, as gas is introduced into a connecting pipe, a honeycomb plate is extruded, internal honeycomb holes are passively opened, and normal saline in a sealing pipe can be fully mixed with the separation liquid.

Description

technical field [0001] The invention relates to the technical field of biological cell extraction, in particular to a device for rapidly separating and extracting biological stem cells based on centrifugal force. Background technique [0002] Biological stem cells are pluripotent cells with self-renewal and self-replication capabilities. Stem cells can be divided into embryonic stem cells and adult stem cells. According to different differentiation potentials, they can be divided into totipotent stem cells, pluripotent stem cells, and unipotent stem cells. In the process of stem cell research, stem cells need to be isolated and extracted. [0003] At present, the steps in the extraction process of biological cells are cumbersome. During the extraction process of many equipment, the physiological saline necessary for cell extraction cannot be fully mixed with the extraction solution, and in the process of cell separation, the effect of sufficient separation cannot be achieved...
