Description

Technical Field

[0001] This utility model relates to the field of cryopreservation tube technology, specifically to an elastic clamping thawing mechanism for a cryopreservation tube thawing device. Background Technology

[0002] In fields such as biomedicine and cell engineering, cryovials are the core carriers for storing biological samples, and their thawing process directly affects the sample's viability and the accuracy of experimental results. Rapid and uniform thawing can effectively avoid problems such as cell rupture and protein denaturation caused by temperature changes. Therefore, developing efficient and safe cryovial thawing technologies is crucial.

[0003] Currently, traditional methods for thawing cryovials mainly include water bath thawing and dry heat thawing. Water bath thawing involves immersing the cryovial in warm water, where heat exchange between the hot water and the cryovial achieves thawing. However, this method has significant drawbacks: firstly, the hot water must indirectly transfer heat to the sample through the cryovial's clamping structure, resulting in low heat transfer efficiency, long delay, and uneven heating of different parts of the cryovial due to the insulation of the clamping structure; secondly, the water bath environment easily leads to cross-contamination of the sample, and residual moisture on the surface of the cryovial can affect subsequent operations.

[0004] To address this issue, the present invention provides an elastic clamping thawing mechanism for a cryopreservation tube thawing device. Utility Model Content

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an elastic clamping thawing mechanism for a cryopreservation tube thawing device, comprising a fixing plate and a pressing assembly, wherein a fixing block is fixedly connected to the fixing plate, and the fixing plate is provided with a slot;

[0007] The extrusion assembly includes an extrusion block and a heating assembly. A fixing member is provided on the inner side of the extrusion block, and a heating probe and a detection probe are provided on the connecting end of the extrusion block.

[0008] Preferably, the fixing plate has a slot, and a first electric actuator is fixedly connected to the inner side of the fixing plate. The output end of the first electric actuator is fixedly connected to a first push rod.

[0009] Preferably, a first connecting rod is rotatably connected to the first push rod, and a rotating component is rotatably connected to the end of the first connecting rod away from the first push rod.

[0014] Beneficial effects

[0015] This invention provides an elastic clamping thawing mechanism for a cryopreservation tube thawing device. Compared with the prior art, it has the following advantages:

[0016] (1) An elastic clamping thawing mechanism for a cryopreservation tube thawing device, wherein a heating probe is embedded in the extrusion block, and the cryopreservation tube can be directly heated against the tube wall when clamping it, thereby avoiding the indirect heat conduction loss of hot water heat through the clamping structure to the cryopreservation tube in traditional water bath or dry heat methods, and reducing heat conduction delay.

[0017] (2) An elastic clamping thawing mechanism for a cryopreservation tube thawing device, wherein the electric push rod drives the extrusion rod to clamp the cryopreservation tube while the heating probe immediately starts heating without any additional steps. The first electric push rod, in conjunction with the linkage mechanism, can automatically adjust the clamping force according to the diameter of the cryopreservation tube, ensuring that the heating probe is in close contact with the tube wall to optimize heat conduction, and avoiding excessive compression that could cause the cryopreservation tube to break.

[0025] 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.

[0026] Example 1:

[0027] Please see Figure 1-5 An elastic clamping thawing mechanism for a cryopreservation tube thawing device includes a fixed plate 1 and a pressing assembly. A fixed block 4 is fixedly connected to the fixed plate 1, and the fixed plate 1 has a slot 2.

[0028] The extrusion assembly includes an extrusion block 121 and a heating assembly 123. A fixing member 122 is provided on the inner side of the extrusion block 121, and a heating probe 125 and a detection probe 126 are provided on the connecting end of the extrusion block 121.

[0029] The fixing plate 1 has a slot 3, and a first electric push rod 5 is fixedly connected to the inner side of the fixing plate 1. A first push rod 6 is fixedly connected to the output end of the first electric push rod 5.

[0030] A first connecting rod 8 is rotatably connected to the first push rod 6, and a rotating component 10 is rotatably connected to the end of the first connecting rod 8 away from the first push rod 6.

[0031] The rotating component 10 is rotatably connected to the second connecting rod 9, and the second connecting rod 9 is rotatably connected to the third connecting rod 7. The third connecting rod 7 is fixedly connected to the inner side of the fixed plate 1.

[0032] A pressing rod 11 is fixedly connected to the rotating part 10, and the pressing assembly is set on the fixed block 4 and the pressing rod 11.

[0033] The heating component 123 is embedded in the extrusion block 121, and the extrusion block 121 is embedded with a temperature sensor 124. The temperature sensor 124 is electrically connected to the detection probe 126, and the heating component 123 is electrically connected to the heating probe 125.

[0034] Working process: Activating the electric actuator 5 pushes the actuator 6 forward, causing the first connecting rod 8 to deflect and the rotating part 10 to rotate. Combined with the pulling action of the connecting rod 7 and the second connecting rod 9, the extrusion rod 11 is pressed inward, clamping the test tube onto the extrusion assembly on the extrusion rod 11 and the extrusion assembly on the fixing block 4. When the test tube is preheated with water, the temperature sensor 124 detects the temperature and the heating assembly 123 heats the probe 125. Heating the test tube with the probe 125 avoids uneven contact between different parts of the cryopreservation tube and the heat source. During the clamping process, the detection probe 126 heats the surface of the test tube, simultaneously with the contact surface of the test tube clamped by the extrusion block 121, thus preventing differences in contact between different parts of the cryopreservation tube and the heat source.
