Problems solved by technology

When performing filtration and extraction of exosomes, the sample must be uniformly and effectively diluted to facilitate subsequent filtration processing. The existing filtration and extraction devices have poor dilution effects and often have unevenness, which affects the subsequent filtration and extraction effect; Therefore, it is necessary to improve the existing technology

Abstract

The invention discloses a filtering and extracting device for stem cell exosome. The filtering and extracting device comprises a base, wherein a diluting cavity and a separating cavity which communicating with each other are distributed on the base at intervals, the diluting cavity and the base are movably installed, a feeding hopper is distributed on one side of the upper end face of the diluting cavity, and a stirring mechanism is distributed in the diluting cavity. The filtering and extracting device for the stem cell exosome drives a driving wheel to operate through a driving motor, so that a stirring shaft drives stirring blades to perform orderly reciprocating rotation, and the cooperation of a vibration mechanism is assisted, so that a diluent and a sample are uniformly and effectively mixed, the dilution quality is ensured, subsequent filtering and extracting are facilitated, through cooperation of an eccentric wheel and a reset spring, a rubber plug can slide in an orderly reciprocating mode along the inner wall of a separation cavity, the filtering and extracting speed can be conveniently controlled, the load exceeding a filtering layer is avoided, and a vertical guide spring is installed on an assembly rod, so that the dilution cavity is oscillated stably, and splashing of the sample and the diluent is avoided.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a device for filtering and extracting stem cell exosomes. Background technique [0002] Stem cells can be said to be a hot spot that has to be paid attention to in the field of biomedicine in recent years. It has great potential in the improvement of human diseases, the delay of aging, and the regeneration of tissues; in many reports on the progress of stem cell research , there is a figure that often appears, that is, exosomes. Exosomes refer to small membrane vesicles (30-150nm) that contain complex RNA and proteins. Nowadays, they specifically refer to disc-shaped vesicles with a diameter of 40-100nm , exosomes are secreted by cells, and a variety of cells can secrete exosomes under normal and pathological conditions. Stem cell exosomes are vesicles secreted by stem cells with a diameter of 40-100 nm. When performing filtration and extraction of exosomes, the sample must be...
