Description

Technical Field

[0001] This utility model relates to the field of umbilical cord blood stem cell transfer technology, specifically to an umbilical cord blood hematopoietic stem cell transfer device. Background Technology

[0002] Umbilical cord blood refers to the blood remaining in the placenta and umbilical cord after the baby is born and the cord is tied and cut. Umbilical cord blood contains a large number of stem cells, including hematopoietic stem cells and various other stem cells, collectively known as umbilical cord blood stem cells. Umbilical cord blood hematopoietic stem cells have been used to save lives for over 30 years. Currently, there are numerous clinical studies on the regenerative medicine applications of umbilical cord blood, aiming to utilize umbilical cord blood stem cells to promote the repair of damaged tissues and organs.

[0003] After separation and processing, umbilical cord blood hematopoietic stem cells are transferred from the processing bag to a specially designed cryopreservation bag, then gradually cooled, and finally stored in a liquid nitrogen tank. However, in existing methods of transferring umbilical cord blood hematopoietic stem cells, the stem cells are usually manually drawn from the processing bag into the cryopreservation bag, which can easily cause blood residue and thus waste of umbilical cord blood hematopoietic stem cells. To address the above problems, the inventors have proposed an umbilical cord blood hematopoietic stem cell transfer device to solve these problems. Utility Model Content

[0004] To address the problem of inconvenience in transferring umbilical cord stem cells from the processing bag to the freezing bag, which easily leads to blood residue, the purpose of this invention is to provide an umbilical cord blood hematopoietic stem cell transfer device.

First, by pressing the lever, the insert rod is disengaged from the fixing block, and the spring is squeezed, allowing the sealing plate to be removed from the first and second frames. Then, the treatment bag is placed in the first frame and the freezing bag is placed in the second frame. Next, the sealing plate is reinstalled in the first and second frames. The lever is released, the spring returns to its original position, and the insert rod is inserted into the fixing block, making it easier to place the treatment bag and freezing bag in the first and second frames. By pulling the telescopic tube, the discharge tube contacts the threaded part. Then, the sleeve is rotated so that the threaded part fits onto the outer surface of the discharge tube. Finally, the valves on the treatment bag and freezing bag are opened, allowing umbilical cord blood hematopoietic stem cells to be transferred from the treatment bag to the freezing bag.

[0006] By turning on the motor, the gears rotate and mesh with the toothed plate, causing the slide rod to slide into the fixed frame and the first frame. This, in turn, pushes the pressure plate to slide within the first frame, thereby compressing the treatment bag and squeezing out the residual blood inside, thus avoiding the waste of umbilical cord blood hematopoietic stem cells.

[0007] Preferably, a sealing plate is detachably provided in both the first frame and the second frame, and a fixing block is fixedly provided on both sides of the sealing plate.

A slide rod 23 is fixedly provided on the top surface of the pressure plate 25. A toothed plate 24 is fixedly provided in the slide rod 23. The gear 22 meshes with the toothed plate 24. The slide rod 23 is slidably inserted into the fixing frame 1. 3. The slide is inserted into the first frame 11. The first frame 11 has a slide groove 111. A slider 26 is fixed on one side of the pressure plate 25. The slider 26 is slidably disposed in the slide groove 111. By turning on the motor 21, the gear 22 is driven to rotate. The gear 22 meshes with the toothed plate 24, causing the slide rod 23 to slide into the fixed frame 1 and the first frame 11, thereby pushing the pressure plate 25 to slide in the first frame 11, thereby compressing the treatment bag 4 and squeezing out the blood remaining in the treatment bag 4, thus avoiding the waste of umbilical cord blood hematopoietic stem cells.

[0022] A sealing plate 13 is detachably provided in both the first frame 11 and the second frame 12. A fixing block 14 is fixedly provided on both sides of the sealing plate 13. A toggle block 15 is slidably provided in both the first frame 11 and the second frame 12. A plug rod 16 is fixedly provided on one side of the toggle block 15 and is inserted into the fixing block 14. A groove 112 is provided in both the first frame 11 and the second frame 12. The toggle block 15 is slidably provided in the groove 112. A spring 17 is fixedly connected between the groove 112 and the toggle block 15.

[0023] By adopting the above technical solution, by pressing the lever 15, the insert rod 16 is disengaged from the fixing block 14, and the spring 17 is squeezed, thereby allowing the sealing plate 13 to be removed from the first frame 11 and the second frame 12. Then, the processing bag 4 is placed in the first frame 11 and the freezing bag is placed in the second frame 12. Next, the sealing plate 13 is reinstalled in the first frame 11 and the second frame 12. The lever 15 is released, the spring 17 returns to its original position, and the insert rod 16 is inserted into the fixing block 14, which facilitates the placement of the processing bag 4 and the freezing bag in the first frame 11 and the second frame 12.

[0024] A processing bag 4 is placed inside the first frame 11, and a freezing bag is placed inside the second frame 12. A discharge pipe 41 is fixedly installed inside the processing bag 4 and the freezing bag. A valve 42 is installed on the outer surface of the discharge pipe 41.

A telescopic tube 32 is fixedly installed inside the sleeve 31. A threaded part 33 is fixedly installed inside the telescopic tube 32. The threaded part 33 is threaded onto the outer surface of the discharge pipe 41.

[0025] By adopting the above technical solution, by pulling the telescopic tube 32, the discharge tube 41 is brought into contact with the threaded part 33. Then, the sleeve 31 is rotated so that the threaded part 33 is fitted onto the outer surface of the discharge tube 41. Then, the valves 42 on the processing bag 4 and the freezing bag are opened so that the umbilical cord blood hematopoietic stem cells are transferred from the processing bag 4 to the freezing bag.

[0026] Working principle: First, by pressing the lever 15, the insertion rod 16 is disengaged from the fixing block 14, and the spring 17 is squeezed, thereby removing the sealing plate 13 from the first frame 11 and the second frame 12. Then, the treatment bag 4 is placed in the first frame 11 and the freezing bag is placed in the second frame 12. Next, the sealing plate 13 is reinstalled in the first frame 11 and the second frame 12. The lever 15 is released, the spring 17 is reset, and the insertion rod 16 is inserted into the fixing block 14, which facilitates the placement of the treatment bag 4 and the freezing bag in the first frame 11 and the second frame 12. By pulling the telescopic tube 32, the discharge tube 41 contacts the threaded part 33. Then, the sleeve 31 is rotated, so that the threaded part 33 is fitted onto the outer surface of the discharge tube 41. Then, the valve 42 on the treatment bag 4 and the freezing bag is opened, so that the umbilical cord blood hematopoietic stem cells are transferred from the treatment bag 4 to the freezing bag.

[0027] By turning on the motor 21, the gear 22 is driven to rotate. The gear 22 meshes with the toothed plate 24, causing the slide rod 23 to slide into the fixed frame 1 and the first frame 11, thereby pushing the pressure plate 25 to slide in the first frame 11, which can compress the treatment bag 4 and squeeze out the blood remaining in the treatment bag 4, thus avoiding the waste of umbilical cord blood hematopoietic stem cells.
