Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only one embodiment of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the described embodiments of this application without creative effort are within the scope of protection of this application.

[0022] Unless otherwise defined, the technical or scientific terms used in this application shall have the ordinary meaning as understood by a person of ordinary skill in the art to which this application pertains.

[0023] This embodiment provides a cryopreservation tube transfer device 10. Figure 1 This is a front-top view of the cryopreservation tube transfer device 10 according to some embodiments of this application; Figure 2 This is a front-lower view of the cryopreservation tube transfer device 10 according to some embodiments of this application; Figure 3 This is a rear-top view of the cryopreservation tube transfer device 10 according to some embodiments of this application; Figure 4 This is a rear-bottom view of the cryopreservation tube transfer device 10 according to some embodiments of this application.

[0024] Cryopreservation tubes (also known as cryovials, biological sample tubes, or cryogenic storage tubes) are specialized containers used in laboratories for long-term cryogenic preservation of biological samples (such as cells, tissues, DNA, RNA, proteins, etc.).

[0025] The cryopreservation tube transfer device 10 includes a main body 100, a rotating component 200, a first clamping part, and a second clamping part. The main body 100 is fixedly equipped with a first rotating shaft 110. The rotating component 200 has a shaft hole and is rotatably connected to the first rotating shaft 110 through the shaft hole. The first clamping part is fixedly connected to the rotating component 200 so that when the rotating component 200 rotates relative to the first rotating shaft 110, the first clamping part also rotates relative to the first rotating shaft 110. The first clamping part has a first position state and a second position state with different positional states due to rotation. The second clamping part is fixed to the lower end of the main body 100. When the first clamping part is in the first position state, the first clamping part and the second clamping part are used to clamp multiple cryopreservation tubes. When the first clamping part is in the second position state, the first clamping part and the second clamping part are used to release the multiple cryopreservation tubes.

[0026] This cryopreservation tube transfer device 10 allows the first clamping part to rotate relative to the first rotating shaft 110, which is fixed to the main body 100. This allows the first clamping part to rotate relative to the main body 100, thereby adjusting the distance between the second clamping part and the main body 100. This enables the clamping and releasing of multiple cryopreservation tubes, improving the efficiency of transferring cryopreservation tubes.

[0027] Specifically, the main body 100 can be a columnar structure. A first connecting portion 120 (e.g., a protrusion) can be fixed to one lateral side of the upper end (i.e., the upper surface) of the main body 100, and a second connecting portion 130 (e.g., a protrusion) can be fixed to the other lateral side. The first connecting portion 120 has a first mounting hole, and the second connecting portion 130 has a second mounting hole. The first lateral end of the first rotating shaft 110 is fixed to the first mounting hole, and the other lateral end of the first rotating shaft 110 is fixed to the second mounting hole. Thus, the first rotating shaft 110 can be fixed simply and stably.

[0028] The rotating component 200 may include a rotating block.

[0029] In some embodiments, the first clamping portion may include a clamping plate 300 (which may be referred to as a pressing block) for clamping the first side of the plurality of cryovials. The length of the clamping plate 300 may be greater than or equal to the diameter of the plurality of cryovials (e.g., 2, 3, 4, etc.), so that the clamping plate 300 can clamp the first side of the plurality of cryovials.

[0030] The first clamping part and the rotating part 200 can be fixedly connected by various methods such as threads, snaps, and integral molding.

[0031] In some embodiments, the second clamping part includes a plurality of (e.g., 3, 4, 5, etc.) clamping posts 400 (which may be referred to as guide pins), and two adjacent clamping posts 400 and the first clamping part are used to clamp one cryopreservation tube. As a result, the clamping is more stable, and the clamping posts 400 are easier to insert into the gap between the cryopreservation tubes in the cryopreservation box.

[0032] The second clamping part can be fixed to the lower end of the main body 100 by various methods such as threads, snaps, or integral molding.

[0033] When the first clamping part is in the first position state, the first clamping part and the second clamping part (referring to the ends away from the first rotating shaft 110) are at a first distance to clamp multiple cryopreservation tubes. When the first clamping part is in the second position state, the first clamping part and the second clamping part are at a second distance to release the multiple cryopreservation tubes. The second distance is greater than the first distance.

[0034] In some embodiments, the bottom end of the clamping post 400 extends in a tapered manner from top to bottom, making it easier to insert into the gap between cryopreservation tubes in the cryopreservation box.

[0035] In some embodiments, the cryopreservation tube transfer device 10 further includes a handle 500, which connects the upper end of the first connecting portion 120 and the upper end of the second connecting portion 130. The handle 500 improves the stability of the overall structure and facilitates user operation.

[0036] In some embodiments, an elastic element is provided between the rotating member 200 and the main body 100; in other embodiments, an elastic element is provided between the rotating member 200 and the rotating shaft; in still other embodiments, an elastic element is provided between the first clamping part and the main body 100; and in yet another embodiment, an elastic element is provided between the first clamping part and the rotating shaft. The elastic element causes the first clamping part to tend to be in a second position when the rotating member 200 is not subjected to external force. This allows the first clamping part to be in the second position when the user does not apply force to the rotating part, facilitating user operation. Specifically, the elastic element can be a spring, a sheet spring, an elastic block, etc.

[0037] In some embodiments, the cryopreservation tube transfer device 10 includes a plurality of rotating members 200 and a plurality of first clamping parts, wherein the plurality of rotating members 200 correspond one-to-one with the plurality of first clamping parts, and each first clamping part is fixedly connected to the corresponding rotating member 200.

[0038] Multiple rotating members 200 can be arranged in a horizontal direction, and multiple first clamping parts can be arranged in a horizontal direction. The cryopreservation tube transfer device 10 may include multiple first rotating shafts 110, each corresponding to one rotating member 200 and one first clamping part. For example, the cryopreservation tube transfer device 10 includes three rotating members 200, three first clamping parts, and three first rotating shafts 110. Each first clamping part can clamp four cryopreservation tubes. The second clamping part may include multiple clamping posts 400 arranged in a horizontal direction, for example, 13 clamping posts 400. Thus, this cryopreservation tube transfer device 10 can transfer 12 cryopreservation tubes at a time.

[0039] In other embodiments, all rotating members 200 are disposed on the same first rotating shaft 110.

[0040] In some embodiments, the plurality of rotating members 200 can be fixedly connected by a linkage (not shown in the figure), and some of the plurality of rotating members 200 have a pressing part 210. Therefore, the user does not need to press all the rotating members 200 simultaneously; pressing only one will cause the other rotating members 200 to rotate under the action of the linkage, improving the user experience.

[0041] In some embodiments, the distance from the rotating member 200 to the first rotating shaft 110 is greater than the distance from the first clamping portion to the first rotating shaft 110. A lever-based force-saving technique is employed, thereby saving effort.

[0042] In some embodiments, a user's cryopreservation tubes are stored in an 8*12 array cryopreservation box, but they want to transfer the cryopreservation box to a 9*14 array cryopreservation box (the 9*14 array cryopreservation box has a larger capacity than the 8*12 array cryopreservation box, which can expand the capacity of consumables by 31.25%). If the cryopreservation tube transfer device 10 of this embodiment is not used, the user needs to manually transfer the cryopreservation tubes from the original 8*12 array cryopreservation box. The cryopreservation tube transfer device 10 of this embodiment can solve the problem of slow transfer of a single tube by the user, and can transfer 12 tubes in a row at the same time, which greatly improves efficiency.

[0043] In other embodiments, if a user finds that an 8*12 array of cryopreservation boxes is damaged during use and needs to replace it with a new one, the cryopreservation tube transfer device 10 of this embodiment can also be used.

[0044] Currently, the transfer of cryopreservation tubes between cryopreservation boxes is done manually, which is time-consuming and labor-intensive. This embodiment utilizes the characteristic of the consumables being arranged in neat rows, allowing 12 tubes to be clamped at once. The technology used allows the fingers to overcome spring pressure and clamp the cryopreservation tubes to achieve transfer.

[0045] In use, the clamping post 400 is inserted offset (i.e., the clamping post 400 is inserted between two adjacent cryovials) into the gap between the farthest row of cryovials and the adjacent second row of cryovials. Using the finger pressing plate to overcome spring resistance, the three first clamping parts clamp the cryovials. After moving to the target cryovial box, the finger is released, releasing the cryovials. Under the action of the spring force, the first clamping parts return to their original position. The same process is repeated for the second row of cryovials, transferring the farthest row of cryovials each time. This embodiment allows for the transfer of up to 12 cryovials at a time, increasing transfer efficiency by up to 12 times.

[0046] Regarding the embodiments of this application, it should also be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other to obtain new embodiments.

[0047] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. The scope of protection of this application shall be determined by the scope of the claims.
