Stem cell filtering separator

Abstract

The invention aims at providing a stem cell filtering separator. The stem cell filtering separator comprises a shell body, a crushing and filtering device, a driving motor, a motor main shaft, a transmission rod, a transmission shaft, a speed reducer, a stirring rotary shaft, an upper stirring blade, a lower stirring blade, a filtering screen, a filtering membrane, a supporting arm, a first vibration absorption backing plate, a supporting plate, a supporting base, a catabolic enzyme injection pipe and an automatic heating device; the stem cell filtering separator is characterized in that the driving motor is arranged at one side of the shell body; the transmission rod is arranged at one side of the driving motor; the motor main shaft is arranged between the driving motor and the transmission rod; the driving motor is connected with the transmission rod through the motor main shaft; the speed reducer is arranged at one side of the transmission rod. According to the stem cell filtering separator provided by the invention, the upper stirring blade, the lower stirring blade and a spiral cutter blade are arranged on the stirring rotary shaft, so that damages, caused by the fact that mechanical forces in a cutting process are not uniform, to a lot of cells are not caused; a stem cell solution can be stirred from various layers, so that the stirring is more uniform, a condition that the filtering screen is blocked by stem cell grains is prevented and the separation and screening efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of stem cell filtration and separation, in particular to a stem cell filtration and separation device. Background technique [0002] At present, stem cells refer to primitive cells with self-renewal and multi-directional differentiation potentials. They are the origin cells of the body and can differentiate into one or more cells that constitute human tissues or organs under specific conditions. Self-renewal refers to the ability of stem cells to maintain the size of the stem cell population through cell division; multidirectional differentiation refers to the plasticity of stem cells, which can differentiate into different tissue cells in different environments to form various complex tissues and organs of the body. Adipose stem cells are a kind of stem cells with multi-directional differentiation potential isolated from adipose tissue in recent years, which can differentiate into osteoblasts, chondrocytes ...

AI Technical Summary

Problems solved by technology

Due to the limitations of the equipment for extracting stem cells, such as complex structure, heavy equipment, large volume, and high price, it is currently only used in a small amount in clinical practice. The survival rate has caused a waste of blood. At present, the most widely used mesenchymal stem cell separation device is a cell screen, which achieves the purpose of separating cells from digested tissue blocks by shaking, stirring and shaking. This stem cell separation method has separation Less efficient, uneven mixing and susceptible to contamination of stem cells
