Description

Technical Field

[0001] This utility model relates to the field of biomedical engineering, and in particular to a stem cell cryopreservation and cooling device. Background Technology

[0002] Stem cells, as a type of cell in living organisms with multi-directional differentiation potential, have stringent requirements for storage. To ensure the integrity and purity of stem cells, they must be stored in a special safe container while maintaining a constant low temperature environment and ensuring a relative humidity of 80%. Therefore, when carrying out stem cell cryopreservation, a cooling device is needed to cool the cell cryopreservation tank containing the stem cells, thus laying the foundation for subsequent long-term cell preservation.

[0003] When storing cryopreservation containers, staff will place them into storage compartments. For cryopreservation containers of different sizes, staff will fill the storage compartments with flexible material to prevent collisions between the containers and the compartments during movement, thus avoiding damage to the containers.

[0004] The existing technology has the following drawbacks: when storing cryopreservation tanks of different sizes, staff need to fill the storage compartments with flexible material one by one to position the cryopreservation tanks. The operation is cumbersome, time-consuming and labor-intensive. Moreover, when taking out cryopreservation tanks, the labels are not easy to observe, which can easily lead to mis-taking and waste a lot of working time. Therefore, a stem cell cryopreservation cooling device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a stem cell cryopreservation cooling device, which aims to improve the problem of cumbersome positioning steps for cryopreservation tanks of different sizes in the prior art.

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.

[0036] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a stem cell cryopreservation cooling device, comprising a cooling chamber 1, a lid 2 hinged to the inner wall of the cooling chamber 1, a slot on the cooling chamber 1 corresponding to the lid 2 for easy rotation of the lid 2, the lid 2 and the cooling chamber 1 being closed using existing technology, a protrusion 15 fixedly connected to the inner wall of the lid 2, a positioning plate 3 slidably connected to the inner wall of the cooling chamber 1, a slot on the cooling chamber 1 corresponding to the positioning plate 3 for easy left and right movement of the positioning plate 3, a compression block 4 fixedly connected to the outer wall of the positioning plate 3, and the positioning plate 3 and a movable plate 8 working together to cool the cryopreservation chamber. For positioning, the left side wall of the extrusion block 4 is elastically connected to the cooling box 1 via a movable spring 5. A fixed plate 6 is fixedly connected to the inner wall of the cooling box 1. A positioning mechanism is provided on the inner wall of the fixed plate 6. The same positioning mechanism as on the fixed plate 6 is provided on the inner wall of the right end of the cooling box 1. A movable component is provided on the inner wall of the cooling box 1. The positioning mechanism includes a movable plate 8. The right side wall of the movable plate 8 is elastically connected to the fixed plate 6 via a movable spring 7. The movable plate 8 is slidably connected to the inner wall of the fixed plate 6. A slot corresponding to the movable plate 8 is provided on the fixed plate 6, allowing the movable plate 8 to move left and right.

[0037] Reference Figure 6 - Figure 8The movable components include a push plate 9, with a slider 11 hinged to its inner wall via a hinge rod 10. A pull rod 12 is fixedly connected to the left side wall of the slider 11, and a plug 13 is elastically connected to the inner wall of the top of the pull rod 12 via a positioning spring 14. The push plate 9 is slidably connected to the inner wall of the cooling box 1. The cooling box 1 has a slot corresponding to the push plate 9, allowing the push plate 9 to move vertically. The inner wall of the push plate 9 is hinged to one end of the hinge rod 10, and the other end of the hinge rod 10 is hinged to the outer wall of the slider 11. Since the length of the hinge rod 10 is fixed, when the slider 11 moves to the left with one end of the hinge rod 10, the other end of the hinge rod 10 will move the push plate 9 upward. When the slider 11 moves to the right with one end of the hinge rod 10, the other end of the hinge rod 10 will move the push plate 9 downward. The slider 11 is slidably connected to the inner wall of the cooling box 1. The cooling box 1 has a slot corresponding to the push plate 9. A slot corresponding to slider 11 allows slider 11 to move left and right. Pull rod 12 passes through and is slidably connected to the inner wall of cooling box 1. Cooling box 1 has a slot corresponding to pull rod 12, allowing pull rod 12 to move left and right. Insert block 13 is inserted into the inner wall of cooling box 1. Insert block 13 is provided with three sets of rectangular blocks. Cooling box 1 has a slot corresponding to the rectangular blocks. The first set of rectangular blocks is initially inserted into the slot. The top inner wall of pull rod 12 is fixedly connected to one end of positioning spring 14. The other end of positioning spring 14 is fixedly connected to the bottom end of insert block 13. When insert block 13 moves downward, positioning spring 14 is compressed. When resetting, the elastic force of positioning spring 14 carries insert block 13 back to its original position. Insert block 13 is slidably connected to the inner wall of pull rod 12. Pull rod 12 has a slot corresponding to insert block 13, allowing insert block 13 to move vertically.

[0038] Reference Figure 3 - Figure 5 The right sidewall of the movable plate 8 is fixedly connected to one end of the movable spring 7, and the other end of the movable spring 7 is fixedly connected to the right inner wall of the fixed plate 6. When the movable plate 8 moves to the right, the movable spring 7 is compressed. When resetting, the movable plate 8 is reset by the elastic force of the movable spring 7. The left sidewall of the pressing block 4 is fixedly connected to one end of the movable spring 5, and the other end of the movable spring 5 is fixedly connected to the left inner wall of the cooling box 1. When the pressing block 4 moves to the right, the movable spring 5 is stretched. When resetting, the pressing block 4 is reset by the elastic force of the movable spring 5. The pressing block 4 is slidably connected to the inner wall of the cooling box 1. The cooling box 1 has a slot corresponding to the pressing block 4, allowing the pressing block 4 to move left and right. The bottom end of the protrusion 15 contacts the top end of the pressing block 4. The pressing block 4 has an inclined surface. When the protrusion 15 presses the inclined surface, the pressing block 4 moves to the right.

[0039] Working principle: When positioning the cryopreservation container, the container is placed between the positioning plate 3 and the movable plate 8. When the container contacts the movable plate 8, it presses against the plate, causing it to move to the right and compress the moving spring 7. The reverse force of the spring 7 allows the movable plate 8 to initially position the container. Then, the lid 2 is flipped over. When the protrusion 15 on the lid 2 contacts and presses against the inclined surface of the compression block 4, the compression block 4 moves to the right and stretches the movable spring 5. The compression block 4 then moves the positioning plate 3 to the right, utilizing the increasing reverse force of the positioning plate 3 and the moving spring 7. To further position the cryogenic container, when the bottom of the lid 2 is in contact with the top of the cooling box 1, the protrusion 15 and the compression block 4 remain stationary. When it is necessary to release the limit, flip the lid 2 by hand. As the protrusion 15 and the compression block 4 are no longer in contact, the elastic force of the movable spring 5 moves the compression block 4 to the initial position. The compression block 4 will move the positioning plate 3 to the right, releasing the positioning of the cryogenic container. As the cryogenic container is no longer in contact with the movable plate 8, the movable plate 8 moves to the initial position under the action of the elastic force of the movable spring 7. If it is necessary to reposition the cryogenic container, simply repeat the above operation steps.

[0040] When the cryogenic container needs to be raised, with the lid 2 open, move the insert block 13 downwards. The insert block 13 will compress the positioning spring 14. When the insert block 13 separates from the slot on the cooling box 1, move the pull rod 12 to the left. The pull rod 12 will move the slider 11 and the hinge rod 10 to the left. The other end of the hinge rod 10 will move the push plate 9 upwards. The push plate 9 will push the cryogenic container upwards, making it easier for staff to pick up and observe the labels. At this time, the insert block 13 aligns with the slot on the cooling box 1. Release the insert block 13, and use the positioning spring... The elastic force of 14 causes the insert 13 to be inserted into the slot of the cooling box 1, thus limiting the push plate 9. When the cryogenic container needs to be retracted, the hand moves the insert 13 downward, and then the hand moves the pull rod 12 to the right. The pull rod 12 will move the slider 11 and the hinge rod 10 to the right. The other end of the hinge rod 10 moves the push plate 9 downward, retracting the cryogenic container. At this time, the hand releases the insert 13, allowing the insert 13 to be inserted into the slot of the cooling box 1, thus limiting the push plate 9. If the push plate 9 needs to be moved again, simply repeat the above operation steps.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
