Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of purification devices, in particular to a stem cell purification device. Background Art
[0002] Adipose stem cells are a type of stem cell with multidirectional differentiation potential isolated from adipose tissue. They mainly restore the repair function of tissue cells and promote cell regeneration. They are expected to become a source of stem cells for repairing damaged tissues and organs. They are currently also widely used to restore breast shape after breast cancer surgery, and provide an important basis for the ultimate successful repair and functional reconstruction of the breast.
[0003] According to a fat stem cell purification device with application number 202121907434.1, a stirring plate, a stirring cover, a stirring column and a motor are provided, and a slider slides inside a corresponding slide groove, and the motor is started, and the motor output shaft drives the rotating column and the stirring plate to rotate. Since the stirring rod installed at the bottom of the stirring column fits the inner wall of the culture dish, after the extracted fat is placed inside the culture dish, the rotating column is rotated so that the stirring rod stirs and breaks the fat. Through this structure, the fat inside can be effectively stirred and decomposed into fat tissue blocks, which saves the time of staff in stirring and decomposing tissue blocks, solves the problem that uneven stirring affects the quality of stem cell extraction from tissue blocks, and improves the working efficiency of the purification device.
[0004] However, the above-mentioned stem cell purification device has certain shortcomings. The stem cells need to be purified at a lower temperature. The device needs to stir the fat during the purification process. During stirring, the stirring rod will convert mechanical energy into friction heat and kinetic energy inside the fat, causing the temperature of the purified fat to increase, thereby reducing the activity and survival rate of the stem cells, which is not convenient for stem cell purification. In addition, the stirring structure of the purification device has certain defects. During stirring, the stirring plate and the stirring rod need to be driven by a motor to rotate to achieve the stirring effect. However, when the stirring plate rotates, the stirring rod will rotate with the stirring plate, and cannot effectively stir the tissue blocks in the culture dish. For this reason, we propose a stem cell purification device. Utility Model Content

DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

[0024] A motor 9 is fixedly installed at the bottom of the purification device body 1, and a mounting frame 10 is fixedly installed at the output end of the motor 9. A plurality of fixing holes 11 are opened inside the mounting frame 10, and a purification test tube 12 is arranged inside the fixing hole 11. The cooling fan 2 cooperates with the purification test tube 12, wherein a fixing groove cooperating with the purification test tube 12 is opened inside the bottom of the mounting frame 10, wherein a rubber clamping ring is arranged inside the fixing hole 11, and its main function is to fix the purification test tube 12 inside the fixing hole 11, and also to avoid the purification test tube 12 idling during purification and stirring. A connecting column 13 is fixedly installed in the middle of the top of the mounting frame 10, and a mounting plate 14 is arranged on the outside of the connecting column 13, and two grooves are arranged inside the mounting plate 14, which The main function of the two middle grooves is to facilitate the taking and installation of the mounting plate 14. A through hole 15 is opened in the middle of the mounting plate 14, and the through hole 15 cooperates with the connecting column 13. The connecting column 13 is rectangular, and a clamping mechanism is arranged inside the connecting column 13. Several stirring rods 22 are rotatably installed inside the mounting plate 14. The interior of the mounting plate 14 is provided with bearings that cooperate with the stirring rods 22. The main function of the bearings is to improve the smoothness of the rotation of the stirring rod 22 to avoid the stirring rod 22 from getting stuck when the gear 24 is meshed with the inner gear ring 25. The stirring rod 22 cooperates with the purification test tube 12, and a gear 24 is fixedly installed on one end of the stirring rod 22.

During purification, the cooling fan 2, the semiconductor refrigeration plate 4 and the motor 9 are turned on at the same time. The motor 9 drives the mounting frame 10 and the mounting plate 14 to rotate. When the mounting plate 14 rotates, the gear 24 engages with the inner gear ring 25 and then drives the stirring rod 22 to rotate to stir and purify the fat tissue in the purification test tube 12. At the same time, when the semiconductor refrigeration plate 4 is turned on, its cooling surface reduces the temperature of the temperature of the heat-conducting copper plate 5. When the cooling fan 2 is turned on, the outside air is blown into the purification device body 1. When the air enters the purification device body 1, it exchanges heat with the heat-conducting copper plate 5, thereby reducing the temperature of the air to cool the purification test tube 12, which is more conducive to the purification of adipose stem cells.
