AI Technical Summary
Technical Problem
In existing technologies, the amount of blood collected by vacuum blood collection tubes is fixed and cannot adapt to the needs of collecting different amounts of blood.
Method used
A stem cell collection device was designed, comprising a blood collection tube, an aspiration assembly, and a cooling assembly. The device enables quantitative collection through a screw-on structure and maintains a low temperature by injecting nitrogen gas.
Benefits of technology
It enables the collection of blood at any time with accurate and quantitative results, and allows for the reuse of the non-blood collection tube portion of the device. It also enables the storage of blood at low temperatures, thus improving collection efficiency and storage time.

Abstract
This disclosure relates to the field of cell collection technology. One embodiment of this disclosure provides a stem cell collection device, which includes: a blood collection tube and a shell, the blood collection tube being located inside the shell; a suction assembly being disposed inside the blood collection tube and the shell; a cooling assembly being disposed on the blood collection tube; the suction assembly includes a blood collection needle disposed at the top of the blood collection tube; the top of the shell has several slots; several inserts are provided on the shell, the inserts being inserted into the slots; and the upper end of the blood collection tube has a first threaded groove. This technical solution solves the problem in the prior art where the amount of blood collected by a vacuum blood collection tube is fixed, while different amounts need to be collected for different types of blood.
