Stem cell separating device

Abstract

The invention provides a stem cell separating device, which comprises a tank and a a driving device, wherein a conical reaction cavity is formed in the tank; an injection conduit and an suction conduit, which are hermetically communicated with the conical reaction cavity, are arranged at the top of the tank; stem cell collecting parts, which are communicated with the conical reaction cavity, are arranged at the lower part of the tank; the stem cell collecting parts and the tank perform exchanging with external substances through the injection conduit and the suction conduit; and the driving device is arranged outside the bottom wall of the tank in a detachable manner, and is used for driving the tank to rotate for vibration or centrifugal separation. The device has the advantages of simplestructure, low cost, fully automatic operation and capability of accurately controlling the efficient separation and extraction of stem cells.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a stem cell separation device. Background technique [0002] Stem cells refer to primitive cells with self-renewal and multi-directional differentiation potential. They are the origin cells of the body. Under certain conditions, they can differentiate into one or more cells that constitute human tissues or organs. They are widely used in basic medical research. 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. [0003] Mesenchymal stem cells (MSCs) are a kind of stem cells, which are derived from mesoderm and ectoderm in the early development stage. received people's attention. Continuously explor...

AI Technical Summary

Problems solved by technology

Continuously exploring and improving the source and method of MSCs acquisition is a necessary prerequisite for in-depth research and utilization of MSCs. At present, there is no unified method for the isolation and cultivation of MSCs. Stem cells

[0004] At present, the separation and extraction process of mesenchymal stem cells is mostly manual operation with a low degree of automation. The separation step is to first inject the stem cell stock solution, water and enzyme into the reaction container for reaction, and then collect the extract to complete the separation step after the reaction is complete. The process steps are cumbersome and random, and it is easy to cause incomplete separation due to human error, which is time-consuming and labor-intensive. At present, there are some stem cell extraction equipment, but these equipment are complex in structure, large in size, and expensive, so they are not suitable for Promotion and application in clinical medicine
