Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a stable stem cell cryopreservation tube holder. Background Technology

[0002] To facilitate stem cell research, stem cells are usually stored in cryovials and then removed from the cryovials for use.

[0003] Patent document CN218962718U discloses a stem cell cryopreservation tube holder, including a frame with several storage slots. The internal fixing mechanism of the storage slots includes a mounting cover, a pressure plate, a mounting shaft, and a connecting rod. Through this fixing mechanism, when a stem cell cryopreservation tube is placed inside the storage slot, the tube presses the pressure plate downwards, causing the clamping element at the top of the connecting rod to adhere to the side wall of the cryopreservation tube, thus clamping the tube and securing it firmly inside the storage slot. The mounting cover is then placed on top of the storage slot. A movable part and a first spring are located at the bottom of the mounting cover. When the cover is closed, the pushing force of the first spring causes the movable part to adhere to the top of the cryopreservation tube, thus simultaneously fixing the top, bottom, and side wall of the cryopreservation tube in conjunction with the pressure plate and clamping element, making the storage of stem cell cryopreservation tubes safer and more stable. However, this patent still has the following problems in actual use:

[0004] This storage rack uses a storage slot, a mounting cover, a rotating shaft, and a gear rack to store individual cryovials. However, when storing and retrieving multiple cryovials, it is difficult to quickly retrieve them, which also increases the production cost of the rack. Furthermore, the size of the storage slot is fixed, making it difficult to stably store smaller cryovials during use, thus resulting in poor practicality of the rack.

[0005] A stable stem cell cryopreservation tube holder is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a stable stem cell cryopreservation tube holder to solve the problems mentioned in the background art. Currently, the holder uses a storage tank, mounting cover, rotating shaft, and gear rack to place a single cryopreservation tube. However, when placing and retrieving multiple cryopreservation tubes, it is difficult to quickly retrieve them, resulting in high production costs. Furthermore, the storage tank is of a fixed size, making it difficult to stably place smaller cryopreservation tubes, thus leading to poor practicality of the holder.

It is easy to push the adjusting block down to make the insert block engage with the slot, so that the placement rack body can be raised. The slot is set in multiple sets, which makes it easy to adjust the height of the placement rack body in the storage box according to the specifications of the cryopreservation tubes, so as to make the storage and retrieval of cryopreservation tubes more convenient and faster, thus making the placement rack more practical.

[0020] 2. Furthermore, the placement rack uses a compression spring and a sliding rod to control the locking and separation of the cover plate and the adjusting block, which is convenient and quick to use. It can store cryopreservation tubes and facilitate their movement. Moreover, the simple structure reduces the production cost of the placement rack, thus making it more practical.

[0021] 3. This placement rack has an adjusting rod in the placement slot of the rack body. By controlling the upper locking block at the bottom of the adjusting plate to engage with the lower locking slot at the top of the rack body, the size of the placement slot can be adjusted according to the size of the cryopreservation tubes. This facilitates the stable placement of the cryopreservation tubes and makes the rack more practical. Attached Figure Description

[0033] Working principle: When using this storage rack, firstly, by pulling the sliding rod 12, the sliding rod 12 causes one side of the clamping block 10 and the compression spring 11 to retract, and pulls the cover plate 13 upward, so that the cover plate 13 is separated from the storage box 1.

[0034] Secondly, by pushing the adjusting block 6 downward in the relief groove 2, the adjusting block 6 slides in the limiting groove 4 on one side of the positioning frame 3, and the adjusting block 6 drives the connecting block 14 to rise through the transmission belt 5. At the same time, the inclined surface below the insert 7 is pushed by the inclined surface of the slot 9 and retracts towards the side of the locking spring 8, and then engages with the slot 9 below, so that the connecting block 14 drives the placement frame body 15 to rise to a suitable height.

[0035] Finally, pull the handle 21 upwards to raise the adjusting plate 18. At this time, the pressing spring 20 contracts, and the upper slot 23 separates from the lower slot 24. Then, move the adjusting plate 18 so that it slides on the outside of the positioning rod 19 through the positioning groove 22, and the adjusting rod 17 and the middle of the placement groove 16 are aligned with the size of the cryopreservation tube. Release the handle 21 so that the upper slot 23 and the lower slot 24 engage, and the cryopreservation tube can be placed in the placement groove 16.
