[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] Example: Figure 1-3As shown, the present invention provides a centrifugal device for stem cells. The base 1 serves as the supporting structure of the entire centrifugal device. A centrifugal mechanism 2 is provided inside the base 1. A plurality of fixing mechanisms 3 for loading and fixing test tubes 30 are fixedly provided inside the centrifugal mechanism 2. A motor 21 serves as the power source of the centrifugal mechanism 2. The output end of the motor 21 is fixedly connected to a rotating rod 27. A driving gear 28 is fixed to the outer surface of the rotating rod 27. The driving gear 28 is connected to a plurality of driven gears 23 through a meshing connection. The upper ends of the driven gears 23 are respectively fixedly connected to the lower ends of the plurality of fixing mechanisms 3. In addition, the inner surface of the base 1 is further provided with tooth grooves 24 for use with the plurality of driven gears 23.

[0017] The support frame 22 fixed at the upper end of the motor 21 is fixedly connected to the lower end of the base 1, which enhances the stability of the motor 21 and ensures the smooth progress of the centrifugal process. The design of the limit frame 25 and the limit block 26 on the lower inner wall effectively limits the axial movement of the rotating rod 27, thereby improving the operating accuracy of the centrifugal mechanism 2. The rotating groove 20 opened at the upper end of the base 1 slides and fits with the upper ends of multiple driven gears 23, reducing the friction resistance when the driven gears 23 rotate and improving the rotation efficiency.

[0018] The fixing mechanism 3 is mainly composed of a fixing cylinder 31. The test tube 30 is placed inside the fixing cylinder 31. A fixing frame 32 is fixed to the outer surface of the fixing cylinder 31. A fixing rod 33 is fixed to the upper and lower inner walls of the fixing frame 32. A spring 37 is sleeved on the outer surface of the fixing rod 33. A fixing wheel 36 is also slidably provided on the outer surface of the fixing rod 33. The outer surface of the fixing wheel 36 is sleeved with a fixing rubber ring 35 for enhancing the fixing effect.

[0019] Multiple fixing mechanisms 3 are distributed in a ring shape at the upper ends of multiple driven gears 23, achieving uniform distribution and simultaneous centrifugal treatment of the test tubes 30, thereby improving work efficiency. The positioning rods 38 on both sides of the fixing wheel 36 are used in conjunction with the positioning grooves 34 on both sides of the fixing frame 32 to ensure stable sliding of the fixing wheel 36 on the fixing rod 33, thereby improving the fixing effect of the fixing mechanism 3. The storage groove 39 opened at the upper end of the fixing cylinder 31 slides in fit with the outer surface of the test tube 30, facilitating the placement and removal of the test tube 30, and at the same time improving the stability of the test tube 30 during centrifugation.

[0020] Working principle: After the motor 21 is started, the centrifugal mechanism 2 drives the rotating rod 27 to rotate through the output end, and then drives the driving gear 28 to rotate. The driving gear 28 drives multiple driven gears 23 to rotate synchronously through meshing connection. Since the driven gear 23 is fixedly connected to the lower end of the fixing mechanism 3, the fixing mechanism 3 also rotates accordingly. During the centrifugation process, the stem cell sample in the test tube 30 is subjected to centrifugal force to achieve separation or purification. The support frame 22 fixed at the upper end of the motor 21 is fixedly connected to the lower end of the base 1, which enhances the stability of the motor 21 and ensures the smooth progress of the centrifugation process. The limit frame 25 and the limit block 26 on its lower inner wall are designed to effectively limit the axial movement of the rotating rod 27, thereby improving the operating accuracy of the centrifugal mechanism 2. The rotating groove 20 opened at the upper end of the base 1 slides and fits with the upper ends of multiple driven gears 23, thereby reducing the friction resistance when the driven gear 23 rotates and improving the rotation efficiency.

[0021] The test tube 30 is placed in the storage slot 39 of the fixed barrel 31 through the fixing mechanism 3. The test tube 30 is firmly fixed through the clamping action of the fixing wheel 36 and the fixing rubber ring 35, as well as the elastic force of the spring 37. During the centrifugation process, even if the test tube 30 is subjected to centrifugal force, it can maintain a stable rotation state, ensuring the accuracy of the centrifugal effect. Multiple fixing mechanisms 3 are distributed in an annular shape on the upper ends of the multiple driven gears 23, achieving uniform distribution and simultaneous centrifugal treatment of the test tubes 30, improving work efficiency. The positioning rods 38 on both sides of the fixing wheel 36 cooperate with the positioning slots 34 on both sides of the fixing frame 32 to ensure the stable sliding of the fixing wheel 36 on the fixing rods 33, improving the fixing effect of the fixing mechanism 3. The storage slot 39 opened at the upper end of the fixing barrel 31 slides and fits with the outer surface of the test tube 30, facilitating the placement and removal of the test tube 30 and improving the stability of the test tube 30 during the centrifugation process.

[0022] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
