It is connected with the inner wall for separating bottle body, the bottom edge of deflector and the arrival end of product outlet connect.Filtered group is prevented to be woven in point
From accumulating on the bottom surface of bottle body, cause the waste of tissue and accumulation rotten.
Fixed link, the traversing through end setting vibration motor of fixed link are worn on the outer wall of the separation bottle body, fixed link is worn
Enter end to be in contact with the outer rim of the second filter screen.Help to improve the extraction efficiency of stem cell
Solenoid valve is set on the inlet tube.The flow velocity for facilitating control tissue prevents raw material inflow from excessively entering and caused
The accumulation organized on strainer reduces filter efficiency.
The cooling device includes the spiral cooling tube of shell and enclosure interior setting.
It is threadedly coupled between separation bottle body and the upper cover body, separates and heat preservation is respectively set on bottle body and the inner wall of upper cover body
Layer.Improve sealing effect and heat insulation effect.
The utility model having the beneficial effect that compared to the prior art
The utility model using double medium filtration web frame improve filter effect, wherein the first filter screen can filter out volume compared with
Big tissue, the second filter screen can efficiently separate mescenchymal stem cell, and filter screen can increase group using inverted conical shape structure
The contact area between filter screen is knitted, filter efficiency is improved；Air inlet pipe I and air inlet pipe II can make the gas of separating bottle inside and outside
Pressure is consistent, and is prevented separation in bottle body and is caused tissue to stop filtration in negative pressure during the filtration process；The setting energy of product outlet
Enough improve the speed and collection rate collected after tissue filter.
