Description

Technical Field

[0001] This utility model relates to the field of cryopreservation technology, and in particular to a cryopreservation device for ultra-low temperature cryopreservation. Background Technology

[0002] Pulmonary embolism specimens typically present as obstructions in the pulmonary artery, with size and shape varying from individual to individual. In pulmonary thromboembolism specimens, the thrombus may completely block the pulmonary artery or be present in smaller branches of the pulmonary artery. The specimen may show the internal texture and structure of the thrombus, which may have a uniform texture or show varying degrees of fibrosis. Pulmonary embolism specimen cryopreservation facilities are used to store tissue, blood, and other samples that require long-term preservation in a cryogenic environment. Cryopreserved specimens are typically stored in a cryogenic environment ranging from -80°C to -196°C to ensure reduced biochemical reactions within the sample and improve the stability of various components within the sample.

[0003] For example, the patent application number published on the China Patent Network is 202121457874.1, and the patent name is: "An ultra-low temperature specimen transport box capable of classified preservation". It includes a base and a transport box body. The top of the base is fixedly connected to a shock-absorbing pad, and the top of the shock-absorbing pad is fixedly connected to the bottom of the transport box body. Multiple storage seats are fixedly connected inside the transport box body. The top of each storage seat is provided with multiple placement slots, and clamping components are provided in the placement slots. This utility model has a reasonable structure and is easy to operate. By setting multiple storage seats, different types of specimens can be placed on different storage seats to achieve classified storage and increase the scope of use. At the same time, the power component can make the fan move horizontally back and forth, thereby blowing cold air back and forth into the transport box body to achieve low temperature storage of specimens. Since the cooling water is circulating, the transport box body can maintain a continuous low temperature, which is more conducive to the preservation of specimens.

[0004] However, existing cryogenic storage equipment mainly stores samples by placing them directly on the platform surface. During the retrieval process, users need to wear gloves and extend their hands into the equipment to retrieve the samples, which is time-consuming and laborious. Moreover, when users select or classify different pulmonary embolism emboli samples, prolonged exposure to the cryogenic environment can easily cause frostbite to the user's hands, affecting the safety of use. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the existing technology of directly stacking specimens is inconvenient for users to handle and is prone to causing frostbite, and to propose an ultra-low temperature cryopreservation specimen storage device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cryopreservation specimen storage device includes a freezer with a door hinged to the front. Inside the freezer is a support cylinder containing several specimen tubes. A bracket is fixedly connected to the rear side of the freezer's inner wall, located on both sides of the support cylinder. A shaft is fixedly connected to both sides of the support cylinder, with the end of the shaft away from the support cylinder passing through the bracket and slidably connected to it. The support cylinder can swing to the outside of the freezer, carrying the specimen tubes, via the shaft.

[0008] As a preferred technical solution of this application, a pressing rod is provided on the right side of the inner wall of the freezer. The right end of the shaft extends through to the right side of the bracket and is fixedly connected to a sleeve plate. The rear end of the pressing rod extends to one side of the sleeve plate and is fixedly connected to a sliding rod. The side of the sliding rod away from the pressing rod extends into the interior of the sleeve plate and is slidably connected to the sleeve plate. The front end of the pressing rod can contact the back of the cabinet door and use the power when the cabinet door is closed to push the sleeve plate to swing and reset the bearing cylinder.

[0009] As a preferred technical solution of this application, a positioning frame is fixedly connected to the right side of the inner wall of the freezer, and the side of the positioning frame away from the freezer extends into the interior of the extrusion rod and is slidably connected to the extrusion rod.

[0010] As a preferred technical solution of this application, the front end of the extrusion rod is movably connected to a roller via a pin, and the outer surface of the roller contacts the back of the cabinet door.

[0011] As a preferred technical solution of this application, a connecting plate is provided at the bottom of the carrier cylinder, and a push rod is fixedly connected to the top of the connecting plate. The top end of the push rod passes through the carrier cylinder and is slidably connected to the carrier cylinder. The connecting plate can carry the push rod up and push the specimen tube inside the carrier cylinder to the outside of the carrier cylinder.

[0012] As a preferred technical solution of this application, the bottom of the connecting plate is fixedly connected with a bearing wheel. The outer surface of the bearing wheel contacts the bottom of the inner wall of the freezer. As the bearing wheel swings with the bearing cylinder, it can contact the rear side of the inner wall of the freezer and carry the connecting plate to the side closer to the bearing cylinder through the squeezing force.

[0013] As a preferred technical solution of this application, an arc-shaped frame is fixedly connected to the bottom of the inner wall of the freezer. The surface of the arc-shaped frame is provided with a groove. The outer surface of the bearing wheel contacts the surface of the arc-shaped frame and generates a vibration force when it contacts the groove. The vibration force generated by the bearing wheel can be transmitted to the connecting plate and shake the specimen tube inside the bearing cylinder through the push rod, thereby reducing the low-temperature adhesion between the specimen tube and the bearing cylinder.

[0014] As a preferred technical solution of this application, an elastic frame is fixedly connected to the rear side of the inner wall of the freezer, and the side of the elastic frame away from the freezer contacts the back of the support cylinder, and the elastic frame is elastic.

[0015] As a preferred technical solution of this application, a limiting rod is fixedly connected longitudinally inside the freezer, a lifting frame is sleeved on the surface of the limiting rod, and a support foot is fixedly connected to the bottom of the lifting frame, the bottom of the support foot being able to contact the bottom of the inner wall of the freezer.

[0016] As a preferred technical solution of this application, the left end of the shaft extends through to the left side of the bracket and is fixedly connected to a wheel. A transmission rod located inside the lifting frame is fixedly connected to the left side of the wheel, and the transmission rod is slidably connected to the wheel.

[0017] Compared with the prior art, this utility model provides a storage device for ultra-low temperature cryopreservation specimens, which has the following beneficial effects:

[0018] 1. This ultra-low temperature cryopreservation specimen storage device, through mechanisms such as the opening and closing of the cabinet door, the sliding connection between the squeezing rod and the sleeve plate, the elastic reset of the elastic frame, the lifting and lowering adjustment of the connecting plate and the pushing rod, the contact shaking of the bearing wheel and the arc frame, and the lifting and lowering adjustment of the limiting rod and the lifting frame, realizes the functions of flexible loading and unloading of specimen tubes, reducing low temperature adhesion, and also has the function of height adjustment of the bearing cylinder. The entire workflow is ingeniously designed, easy to operate, safe and reliable, and effectively improves the storage efficiency and convenience of the ultra-low temperature cryopreservation specimen bank.

[0019] 2. This ultra-low temperature cryopreservation specimen storage device, through the cooperative design of the compression rod, sleeve plate, and slide rod, enables the cabinet door to use its own power to push the sleeve plate when closed, thereby causing the bearing cylinder to swing and reset. This not only simplifies the operation process but also improves the automation level of the equipment.

[0020] 3. The ultra-low temperature cryopreservation specimen storage device provides a stable sliding track for the squeezing rod through the addition of a positioning frame, ensuring the smoothness and accuracy of the squeezing rod during movement and helping to maintain the stability of the support cylinder during swinging and resetting.

[0021] 4. The ultra-low temperature cryopreservation specimen storage device reduces friction between the compression rod and the cabinet door through the roller design, extending the service life of the equipment. At the same time, the roller also allows the compression rod to move more smoothly with the movement of the cabinet door, further improving the automation and convenience of the equipment.

[0022] 5. This ultra-low temperature cryopreservation specimen storage device, through the cooperative design of the connecting plate and the push rod, allows operators to easily push the specimen tubes inside the carrier cylinder to the outside, realizing the rapid loading and unloading of specimen tubes, improving work efficiency, and at the same time keeping the inside of the freezer clean.

[0023] 6. The ultra-low temperature cryopreservation specimen storage device, through the design of the bearing wheel, allows the connecting plate to contact the rear side of the inner wall of the freezer during the swinging process of following the bearing cylinder, and to move towards the side closer to the bearing cylinder through the extrusion force. This helps to maintain the stability of the connecting plate and the push rod during the swinging process, while improving the flexibility of the equipment.

[0024] 7. The ultra-low temperature cryopreservation specimen storage device, through the design of the arc frame and groove, enables the bearing wheel to generate vibration force when it contacts the arc frame. This vibration force can be transmitted to the connecting plate and shake the specimen tubes inside the bearing cylinder through the push rod, thereby reducing the low temperature adhesion between the specimen tubes and the bearing cylinder.

[0025] 8. The ultra-low temperature cryopreservation specimen storage device provides additional support to the support tube through the design of the elastic frame, which helps to maintain the stability of the support tube during swinging and resetting. At the same time, the elasticity of the elastic frame can also absorb some of the vibration and impact force, further protecting the safety of the specimen tube.

[0026] 9. The ultra-low temperature cryopreservation specimen storage device, through the design of the limiting rod and lifting frame, allows operators to easily adjust the height of the carrying cylinder, thereby adapting to specimen tubes of different sizes or different storage and retrieval needs, improving the flexibility and adaptability of the equipment.

[0027] 10. This ultra-low temperature cryopreservation specimen storage device, through the coordinated design of the rotating wheel and transmission rod, enables the lifting frame to drive the swing of the carrying cylinder, realizing dual adjustment of the height and swing angle of the carrying cylinder, further improving the flexibility and convenience of the equipment, and allowing operators to more accurately control the storage and retrieval position of specimen tubes.

[0037] Reference Figure 1-6 This utility model provides an ultra-low temperature cryopreservation specimen storage device, including a freezer 1, a door 2 hinged to the front of the freezer 1, a support cylinder 3 inside the freezer 1, and a number of specimen test tubes 4 inserted inside the support cylinder 3.

[0038] A bracket 5 is fixedly connected to the rear side of the inner wall of the freezer 1. The bracket 5 is located on both sides of the support cylinder 3. A shaft 6 is fixedly connected to both sides of the support cylinder 3. The end of the shaft 6 away from the support cylinder 3 passes through the bracket 5 and is slidably connected to the bracket 5. The support cylinder 3 can swing to the outside of the freezer 1 by carrying the specimen tube 4 through the shaft 6. Through the opening and closing of the cabinet door 2, the sliding connection between the squeezing rod 7 and the sleeve plate 8, the elastic reset of the elastic frame 17, the lifting and lowering adjustment of the connecting plate 12 and the pushing rod 13, the contact shaking between the support wheel 14 and the arc frame 15, and the lifting and lowering adjustment of the limit rod 18 and the lifting frame 19, the flexible loading and unloading of the specimen tube 4, the reduction of low temperature adhesion, and the height adjustment of the support cylinder 3 are realized. The entire workflow is ingeniously designed, easy to operate, safe and reliable, and effectively improves the storage efficiency and convenience of the ultra-low temperature frozen specimen bank.

[0039] A pressing rod 7 is provided on the right side of the inner wall of the freezer 1. The right end of the shaft 6 passes through to the right side of the bracket 5 and is fixedly connected to the sleeve plate 8. The rear end of the pressing rod 7 extends to one side of the sleeve plate 8 and is fixedly connected to the slide rod 9. The side of the slide rod 9 away from the pressing rod 7 extends into the interior of the sleeve plate 8 and is slidably connected to the sleeve plate 8. The front end of the pressing rod 7 can contact the back of the cabinet door 2 and use the power of the cabinet door 2 when it is closed to push the sleeve plate 8 to swing and reset the bearing cylinder 3. A positioning frame 10 is fixedly connected to the right side of the inner wall of the freezer 1. The side of the positioning frame 10 away from the freezer 1 extends into the interior of the pressing rod 7 and is slidably connected to the pressing rod 7.

[0040] In the specific technical solution, the front end of the extrusion rod 7 is movably connected to a roller 11 via a pin. The outer surface of the roller 11 contacts the back of the cabinet door 2. A connecting plate 12 is provided at the bottom of the support cylinder 3, and a push rod 13 is fixedly connected to the top of the connecting plate 12. The top end of the push rod 13 passes through the support cylinder 3 and is slidably connected to it. The connecting plate 12 can carry the push rod 13 upward and push the specimen tube 4 inside the support cylinder 3 to the outside of the support cylinder 3. A support wheel 14 is fixedly connected to the bottom of the connecting plate 12, and the outer surface of the support wheel 14 contacts the bottom of the inner wall of the freezer 1. As the support wheel 14 swings with the support cylinder 3, it can contact the rear side of the inner wall of the freezer 1 and, through extrusion force, move the connecting plate 12 towards the side closer to the support cylinder 3.

[0041] In the specific technical solution, an arc-shaped frame 15 is fixedly connected to the bottom of the inner wall of the freezer 1. The surface of the arc-shaped frame 15 is provided with a groove 16. The outer surface of the bearing wheel 14 contacts the surface of the arc-shaped frame 15 and generates a vibration force when it contacts the groove 16. The vibration force generated by the bearing wheel 14 can be transmitted to the connecting plate 12 and shake the specimen tube 4 inside the bearing cylinder 3 through the push rod 13, thereby reducing the low-temperature adhesion between the specimen tube 4 and the bearing cylinder 3.

[0042] In the specific technical solution, a spring frame 17 is fixedly connected to the rear side of the inner wall of the freezer 1. The side of the spring frame 17 away from the freezer 1 contacts the back of the bearing cylinder 3. The spring frame 17 is elastic. A limit rod 18 is fixedly connected longitudinally inside the freezer 1. A lifting frame 19 is sleeved on the surface of the limit rod 18. A support leg 20 is fixedly connected to the bottom of the lifting frame 19. The bottom of the support leg 20 can contact the bottom of the inner wall of the freezer 1. The left end of the shaft 6 passes through to the left side of the bracket 5 and is fixedly connected to a rotating wheel 21. A transmission rod 22 located inside the lifting frame 19 is fixedly connected to the left side of the rotating wheel 21. The transmission rod 22 is slidably connected to the rotating wheel 21.

[0043] Specifically, in the ultra-low temperature cryopreservation specimen storage device provided in this embodiment of the present invention, when the device is not in use, the support cylinder 3 is located inside the freezer 1, the specimen tube 4 is inserted into the support cylinder 3, the shaft 6 passes through the bracket 5 and is slidably connected to the bracket 5, so that the support cylinder 3 can swing within a certain range, the cabinet door 2 is tightly closed, and the interior of the freezer 1 maintains an ultra-low temperature environment.

[0044] When it is necessary to remove or place specimen tube 4, the operator opens cabinet door 2. At this time, because cabinet door 2 is in contact with the roller 11 at the front end of squeezing rod 7 and moves as cabinet door 2 is opened, squeezing rod 7 disengages from cabinet door 2 and moves forward. When squeezing rod 7 moves forward, it pushes sleeve plate 8 and the connected shaft rod 6 and bearing cylinder 3 to swing out of freezer 1 through sliding connection of slide rod 9 and sleeve plate 8. During this process, bearing cylinder 3 carries specimen tube 4 and swings together, making it convenient for the operator to remove and place.

[0045] During the swinging process of the support cylinder 3, the support wheel 14 contacts the bottom of the inner wall of the freezer 1 and the arc frame 15. When the support wheel 14 contacts the groove 16 on the surface of the arc frame 15, a vibration force is generated. This vibration force is transmitted to the push rod 13 through the connecting plate 12, which in turn causes the specimen tube 4 inside the support cylinder 3 to shake slightly, which helps to reduce the low-temperature adhesion between the specimen tube 4 and the support cylinder 3.

[0046] Simultaneously, the continuously moving connecting plate 12 can use the push rod 13 to push the specimen tube 4 inside the support cylinder 3, moving it to the outside of the support cylinder 3 for easy access by the user. The device is also equipped with a limit rod 18 and a lifting frame 19. The lifting frame 19 contacts the bottom of the inner wall of the freezer 1 via the support legs 20 and can slide on the limit rod 18. When the support cylinder 3 needs to swing outward, the support cylinder 3 uses the shaft 6 to drive the rotating wheel 21 to rotate. The rotating wheel 21 drives the transmission rod 22 to slide inside the lifting frame 19 and push the lifting frame 19 down. When the support legs 20 at the bottom of the lifting frame 19 contact the bottom of the inner wall of the freezer 1, the support for the support cylinder 3 is completed.

[0047] In summary, the ultra-low temperature cryopreservation specimen storage device provided by this utility model realizes the functions of flexible placement and removal of specimen tubes, reducing low temperature adhesion, and adjusting the height of the support cylinder. The entire workflow is ingeniously designed, easy to operate, safe and reliable, and effectively improves the storage efficiency and convenience of ultra-low temperature cryopreservation specimen storage.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
