Description

Technical Field

[0001] This utility model relates to the field of stem cell suspension anti-settling technology, specifically a device for preventing stem cell suspension from settling. Background Technology

[0002] The preparation of stem cell suspension involves preparing animal tissue material containing stem cells into a single-cell suspension. Tissue extraction determines the location of the desired stem cells in the body and obtains the tissue from that location. This allows for the acquisition of the target stem cells while also achieving preliminary enrichment. During storage, stem cells will gradually settle from a suspended state, thus affecting the effectiveness of the suspension.

[0003] The existing patent with authorization announcement number "CN214612532U" discloses a device for preventing stem cell suspension sedimentation, comprising a base, a suspension bracket, a protective cover, a motor, a square magnet, and an infusion bag. A tachometer, a light alarm, and a switch are installed on the front surface of the base. A battery is installed on the lower surface of the base, and a motor is installed inside the base. A square magnet is installed on the upper surface of the motor, and a speed sensor is installed on the lower surface of the square magnet. Compared with the prior art, this utility model has the following advantages: by adding a magnetic ball, an isolation sleeve, a square magnet, and a motor, the problem of cell sedimentation is completely solved. Furthermore, the device is compact, practical, and noiseless, facilitating large-scale promotion.

[0004] However, this device has the following shortcomings:

[0005] 1. When using the above device, the stem cell suspension has poor fluidity, which causes the stem cell suspension to settle, reducing the effectiveness of the stem cell suspension.

[0006] 2. The above-mentioned device has poor stirring effect on stem cell suspension. When the stem cell suspension is discharged, it is difficult to stir the suspension, resulting in uneven distribution of stem cells in the stem cell suspension. Utility Model Content

[0007] The purpose of this invention is to provide a device for preventing the sedimentation of stem cell suspensions, thereby solving the existing problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a device for preventing the sedimentation of stem cell suspension, comprising a base, mounting frames on both sides of the top of the base, support columns on both sides of the inner side of the mounting frames, a roller sleeved on the outer side of the two sets of support columns, an external toothed ring in the middle of the outer side of the roller, a motor at the bottom of one side of the mounting frame, a rotating rod at the output end of the motor, a gear in the middle of the outer side of the rotating rod, and an inlet pipe and an outlet pipe respectively on the inner side of the two sets of support columns;

[0009] The two sets of support columns are connected by a connecting plate on one side. Sleeves are provided on both sides of the bottom of the connecting plate. Guide rods are slidably inserted into the inner sides of the two sets of sleeves. Weights are provided at the bottom of the two sets of guide rods.

A stirring assembly is provided at the bottom of one side of the mounting frame.

[0010] Preferably, the stirring assembly includes a water pump, a stirring drum, and a stirring rod. The stirring drum is located at the bottom of the mounting frame away from the motor, and the water pump is located in the middle of one side of the mounting frame. The outlet pipe is connected to the input end of the water pump, and the output end of the water pump is connected to the stirring drum. A stirring rod connected to a rotating rod is sleeved on one side of the stirring drum, which can stir the stem cell suspension when it is discharged, thereby improving the uniformity of the stem cell suspension.

[0011] Preferably, protective covers are provided on both sides of the bottom inside the roller, and the protective covers are made of plastic. The two sets of magnetic blocks A are located inside the protective covers, which can protect the magnetic blocks A.

[0012] Preferably, the top of the base is provided with limit plates on both sides near the mounting frame, and the two sets of limit plates are sleeved on the outside of the rotating rod to limit the rotation of the rotating rod and improve the rotational stability of the rotating rod.

[0013] Preferably, magnetic block A and magnetic block B are opposite each other with the same pole, so that when magnetic block A rotates to the bottom of the drum, it can push the drop block to move upward by utilizing the principle of repulsion between magnetic block A and magnetic block B with the same pole.

[0015] Preferably, both the motor and the water pump are provided with protective shells on their outer sides, which can protect the motor and the water pump and extend their service life.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the device for preventing stem cell suspension from settling;

[0017] 1. Through the cooperation of the motor, drum, external gear ring, rotating rod, gear, magnetic block A, drop block, sleeve, turbulence rod, magnetic block B and guide rod, the device can store stem cell suspension in the drum during use. By controlling the continuous rotation of the drum, the stem cell suspension can roll in the drum, which improves the fluidity of the stem cell suspension and prevents the stem cell suspension from settling. At the same time, when the drum rotates, the principle of magnetic repulsion between magnetic block A and turbulence rod can be used to intermittently push the turbulence rod up and down, thereby improving the turbulence effect on the stem cell suspension and further improving the anti-settling ability of the suspension.

[0018] 2. Through the cooperation between the motor, rotating rod, stirring drum, and stirring rod, the device can simultaneously drive the stirring rod to rotate when driving the drum to rotate. Thus, when the stem cell suspension is drawn from the drum into the stirring drum, the rotation of the stirring rod can further stir the stem cell suspension, thereby improving the uniformity of the stem cell suspension and ensuring the effectiveness of the suspension.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4The present invention provides an embodiment of a device for preventing the sedimentation of stem cell suspension, comprising a base 1, mounting frames 8 on both sides of the top of the base 1, support columns 4 on both sides of the inner side of the mounting frames 8, a roller 5 sleeved on the outer side of the two sets of support columns 4, an external toothed ring 7 in the middle of the outer side of the roller 5, a motor 2 at the bottom of one side of the mounting frame 8, a rotating rod 13 at the output end of the motor 2, a gear 14 in the middle of the outer side of the rotating rod 13, and an inlet pipe 3 and an outlet pipe 9 respectively on the inner side of the two sets of support columns 4.

[0026] Two sets of support columns 4 are connected by a connecting plate 6 on one side. Sleeves 17 are provided on both sides of the bottom of the connecting plate 6. Guide rods 20 are slidably inserted into the inner side of the two sets of sleeves 17. A drop block 16 is provided at the bottom of the two sets of guide rods 20. A baffle rod 18 is provided on both sides of the two sets of drop blocks 16. A magnetic block B19 is provided inside the two sets of drop blocks 16. A magnetic block A15 that cooperates with the magnetic block B19 is provided on both sides of the bottom of the inside of the drum 5. A stirring component is provided at the bottom of one side of the mounting frame 8.

[0027] The stirring assembly includes a water pump 10, a stirring drum 11, and a stirring rod 12. The stirring drum 11 is located at the bottom of the mounting frame 8 on the side away from the motor 2. The water pump 10 is located in the middle of one side of the mounting frame 8. The outlet pipe 9 is connected to the input end of the water pump 10, and the output end of the water pump 10 is connected to the stirring drum 11. The stirring rod 12, which is connected to the rotating rod 13, is sleeved on one side of the stirring drum 11. This allows the stem cell suspension to be stirred when it is discharged, thus improving the uniformity of the stem cell suspension.

[0028] Furthermore, protective covers are provided on both sides of the bottom inside the roller 5, and the protective covers are made of plastic. Two sets of magnetic blocks A15 are located inside the protective covers, which can protect the magnetic blocks A15 and prevent the magnetic blocks A15 from directly contacting the stem cell suspension.

[0029] Furthermore, limit plates are provided on both sides of the top of the base 1 near the mounting bracket 8, and the two sets of limit plates are sleeved on the outside of the rotating rod 13 to limit the rotation of the rotating rod 13, thereby improving the rotational stability of the rotating rod 13.

[0030] Furthermore, magnetic block A15 and magnetic block B19 are opposite each other with the same pole, so that when magnetic block A15 rotates to the bottom of roller 5, it can push the drop block 16 upward by utilizing the principle of repulsion between the same poles of magnetic block A15 and magnetic block B19.

[0031] Furthermore, a limit block is provided at the top of the guide rod 20 to limit the range of motion of the guide rod 20.

[0032] Furthermore, both the motor 2 and the water pump 10 are provided with protective shells on their outer sides. These protective shells can protect the motor 2 and the water pump 10 and extend their service life.

[0033] Working principle: When in use, the stem cell suspension can be transported into the drum 5 through the liquid inlet pipe 3. When storing the stem cell suspension, the motor 2 can be started to run. The motor 2 can drive the rotating rod 13 to rotate, and then the rotating rod 13 drives the gear 14, so that the gear 14 can drive the meshing external tooth ring 7 to rotate the drum 5. Through the rotation of the drum 5, the stem cell suspension in the drum 5 can be continuously rolled, which improves the fluidity of the stem cell suspension and thus prevents the suspension from settling.

[0034] When the drum 5 rotates, it can drive the two sets of magnetic blocks A15 to rotate. When the two sets of magnetic blocks A15 rotate to the bottom, the principle of like poles repulsion between magnetic blocks A15 and B19 can push the drop block 16 to move upward. When magnetic blocks A15 continue to rotate, magnetic blocks B19 and magnetic blocks A15 lose their magnetic force, and the drop block 16 can move downward under the action of gravity, thereby driving the turbulence rod 18 to move up and down to turbulent the stem cell suspension and improve the anti-settling ability of the stem cell suspension.

[0035] When the stem cell suspension is extracted by the water pump 10, the stem cell suspension flows into the stirring tank 11 through the outlet pipe 9. The stirring rod 12 can be rotated by the rotating rod 13, and the discharged stem cell suspension can be stirred again by the stirring rod 12, which improves the uniformity of the stem cell suspension.
