Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the illustrated embodiments are provided to explain the present invention and not to limit the scope of the invention.
Example one
Referring to fig. 1, the present embodiment provides a stem cell storage protection and extraction device, the device includes a storage mechanism 1, a drawing mechanism 2 is slidably connected to a right end of the storage mechanism 1, and a first filtering mechanism 11 and a second filtering mechanism 12 are respectively disposed on a left end face of the storage mechanism 1. Still rotate on the 1 left side terminal surface of storage mechanism and be connected with a carousel 3, be equipped with a spacing through-hole 31 on carousel 3 for when rotating carousel 3 spacing through-hole passes through first filter mechanism 11, second filter mechanism 12 in proper order, the left side terminal surface of carousel 3 is equipped with sealing mechanism 4, sealing mechanism 4's side is through connecting portion 5 and 1 side fixed connection of storage mechanism, and sealing mechanism 4's left side terminal surface is equipped with first syringe needle 41 and second syringe needle 42 respectively, first syringe needle 41 suits with first filter mechanism 11, second filter mechanism 12 respectively with second syringe needle 42's position.
In some embodiments, the storage mechanism 1 is a hollow cylindrical barrel, and in other embodiments, the storage mechanism 1 may have other shapes according to actual needs. The outer side wall of the rotating disc 3 can be a rough surface so as to facilitate rotation.
The drawing mechanism 2 comprises a straight rod 21, and the straight rod 21 penetrates through the right end face of the storage mechanism 1 and can slide relative to the storage mechanism 1.
