Description

Technical Field

[0001] This invention relates to the field of placement rack technology, and more specifically to a sika deer embryo cryopreservation rack. Background Technology

[0002] Sika deer embryo freezing requires freezing in liquid nitrogen at -196℃ to completely stop cell metabolism. Then, based on the characteristics of the frozen embryo, it is viable for long-term preservation so that it can be thawed and transplanted at any time, without being limited by the season or the mother deer's body. Therefore, when freezing sika deer embryos, a placement rack is needed to assist in the process. This rack vertically positions the cannula containing the embryos and separates each cannula, then labels it with text. This makes it easy to distinguish the embryos and prevents them from floating around or getting tangled together when directly placed into the liquid nitrogen tank. It also prevents some embryo cannulas from being lost. In summary, the inventors have found that the existing placement rack has the following main defects: When a large number of sika deer embryos are loaded into the liquid nitrogen tank, the overall weight is relatively light and it is easy for the embryos to become unstable and float upwards, resulting in tilting. This reduces the stability of the vertical freezing of sika deer embryos carried by the current placement rack. At the same time, due to the tilt, the embryos on the left and right sides will freeze to an inconsistent degree, and some embryos are very likely to be half frozen and half not frozen. Summary of the Invention

[0003] The technical solution adopted by the present invention to achieve the technical objective is: a sika deer embryo cryopreservation rack, the structure of which includes: an auxiliary structure, an assembly frame, a connecting rod, a placement tray, and a cryopreservation structure. The position of the connecting rod and the placement tray is determined by the assembly frame on the inner side of the auxiliary structure. A plurality of cryopreservation structures are mounted on the placement tray and set one by one in parallel orientation.

[0004] As a further improvement of the present invention, the auxiliary structure includes a bottom block, a parallel plate, an anti-deviation column, a top plate, a pull block, an auxiliary groove, and a pressing block. The upper end of the bottom block is connected to the lower end of the parallel plate. The edge of the parallel plate is connected to the edge of the top plate through the anti-deviation column and controlled by the upper pull block. The auxiliary grooves on the left and right sides of the top plate surface allow the pressing block to be embedded.

[0005] As a further improvement of the present invention, the anti-deviation column is also provided with an assembly end, a column body, a splicing block, and a slider. The assembly end is located on the surface of the column body and the upper and lower ends of the column body are integrated with the splicing block. The other side of the column body contacts the inner wall of the liquid nitrogen tank through the slider.

[0006] As a further improvement of the present invention, the lower bottom block of the parallel plate of the auxiliary structure is interwoven with the bottom layer inside the liquid nitrogen tank, while the auxiliary groove of the top plate allows the pressing block to be embedded and filled to increase the weight. As a result, the slider of the anti-deviation column will contact the inner wall of the liquid nitrogen tank, and then be fixed by interleaving the assembly end with the assembly frame.

[0007] As a further improvement of the present invention, the auxiliary structure is spliced ​​with the assembly frame to form a complete placement rack. Four connecting rods are provided at the corners of the assembly frame to connect with the upper and lower assembly frames in parallel to form a multi-layer shape. The placement tray is set in a parallel orientation to position multiple sets of freezing structures.

[0008] As a further improvement of the present invention, the bottom block is a solid protrusion and is integrated with the lower layer of the parallel plate. The anti-deviation column of the parallel plate is set in a vertical position. The surface of the pull block on the top plate is equipped with a sponge pad for direct contact with the hand. Two sets of auxiliary grooves and pressing blocks are provided and set in a symmetrical position on the top plate.

[0009] As a further improvement of the present invention, the assembly end and the assembly frame are shaped to match each other, the column is solid and vertical and the slider is solid and protruding to contact the inner wall of the liquid nitrogen tank, and the column is connected to the top plate and the edge of the parallel plate by splicing blocks at the upper and lower ends.

[0010] As a further improvement of the present invention, the pressing block is further provided with an insert block, the upper end of the insert block is connected to a magnetic suction plate, a solid block is provided on the upper layer of the magnetic suction plate, and a control groove is opened on the edge of the solid block.

[0011] As a further improvement of the present invention, the insert block and the magnetic suction plate are perpendicular to each other and the solid block and the magnetic suction plate are parallel to each other, and the control groove is a recessed hollow shape and is symmetrically opened on the left and right sides of the solid block.

[0012] As a further improvement of the present invention, the assembly end is also provided with a contact layer, the edge of the contact layer is provided with a limit block, the outer center of the limit block is provided with a restraining block, the center of the restraining block is penetrated by a slide rod, the upper end of the slide rod is provided with a pushing block and the center position is also provided with a locking bolt, and the lower end of the slide rod is also connected with a clamping block.

[0013] As a further improvement of the present invention, the contact layer is in a parallel shape and contacts the assembly frame, the limiting block allows the slide rod to pass through vertically through the restraining block, and the clamping block at the lower end of the slide rod contacts the edge of the assembly frame.

[0014] As a further improvement of the present invention, the freezing structure is provided with a label ring, and a positioning ring is provided on the inner wall of the label ring. The positioning ring has an anti-slip surface on its center and a through groove at its center position, through which the freezing tube is positioned.

[0015] As a further improvement of the present invention, the label ring and the positioning ring are located at the same center point, the anti-slip surface is provided with anti-slip texture, the through groove is circular and opened in a vertical direction to allow the freezing tube to pass through, and the freezing tube is "T" shaped.

[0016] As a further improvement of the present invention, the freezing tube is also provided with a hand-held block, the lower end of which is connected to a cover plate, and the lower end of the cover plate is connected to a locking body. The locking body is adapted to the locking layer position and communicates with the freezing tank. Both the freezing tank and the locking layer are located inside the tube body.

[0017] As a further improvement of the present invention, the cover plate is connected to the locking layer of the tube body through the locking body to form a stable "T"-shaped through-slot position.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. With the improvement of the auxiliary structure, the bottom block at the lower end of the parallel plate can be inserted into the bottom of the liquid nitrogen tank. During the process, the slider of the anti-deviation column is used to keep it vertical and prevent tilting. Then, the pressing block is inserted through the auxiliary groove of the top plate to increase the weight and prevent floating due to insufficient weight. This improves the accuracy and stability of the freezing rack carrying sika deer embryos for freezing and avoids unevenness and shaking.

[0019] 2. This invention improves upon the pressing block and assembly end by using a magnetic plate at the lower end of the solid block in conjunction with an insert block. After vertical insertion into the auxiliary slot, the insert block positions the block and the magnetic plate secures it, enhancing the connection's firmness and preventing automatic detachment. Subsequently, after the contact layer of the assembly end contacts the assembly frame, the upper and lower sliding rods drive the clamping blocks to clamp and fix the edges of the assembly frame, improving the fixation effect. Furthermore, the ease of disassembly facilitates subsequent disassembly and maintenance, avoiding the wobbling and instability that occurs with simple splicing, and further improving stability during freezing.

[0020] 3. With the improved freezing structure, this invention allows for precise labeling of each group of embryos through the external tag ring of the positioning ring, improving identification accuracy. Furthermore, the anti-slip surface and through-groove of the positioning ring can be adapted to the freezing tube, allowing the embryos to pass through the through-groove of the positioning ring after being placed in the freezing tank and covered by the cover plate. The edge of the cover plate then contacts the anti-slip surface, forming a stable cross-positioning effect, further improving the stability during freezing and preventing liquid nitrogen from entering the tube and directly contacting the embryos.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings: Example 1: Figures 1 to 5 As shown: This invention provides a sika deer embryo cryopreservation rack. Its structure includes: auxiliary structure 1, assembly frame 2, connecting rod 3, placement tray 4, and freezing structure 5. The position of connecting rod 3 and placement tray 4 is determined by the assembly frame 2 on the inner side of the auxiliary structure 1. A number of freezing structures 5 are mounted on the placement tray 5 and set one by one in parallel orientation.

[0030] The auxiliary structure 1 includes a bottom block 11, a parallel plate 12, an anti-deviation column 13, a top plate 14, a pull block 15, an auxiliary groove 16, and a pressing block 17. The upper end of the bottom block 11 is connected to the lower end of the parallel plate 12. The edge of the parallel plate 12 is connected to the edge of the top plate 14 through the anti-deviation column 13 and controlled by the upper pull block 15. The auxiliary groove 16 on the left and right sides of the surface of the top plate 14 allows the pressing block 17 to be embedded.

[0031] The anti-deviation column 13 is also provided with an assembly end 131, a column body 132, a splicing block 133, and a slider 134. The assembly end 131 is located on the surface of the column body 132, and the upper and lower ends of the column body 132 are integrated with the splicing block 133. The other side of the column body 132 contacts the inner wall of the liquid nitrogen tank through the slider 134.

[0032] In this process, the lower bottom block 11 of the parallel plate 12 of the auxiliary structure 1 intersects with the bottom layer inside the liquid nitrogen tank, while the auxiliary groove 16 of the top plate 14 allows the pressing block 17 to be embedded and filled to increase the weight. As a result, the slider 134 of the anti-deviation column 13 will contact the inner wall of the liquid nitrogen tank, and then be interspersed and fixed with the assembly frame 2 through the assembly end 131.

[0033] The auxiliary structure 1 is assembled with the assembly frame 2 to form a complete placement rack. The corners of the assembly frame 2 are provided with four connecting rods 3 to connect with the upper and lower assembly frames 3 in parallel to form a multi-layer shape. The placement tray 4 is set in a parallel orientation to position multiple sets of freezing structures 5.

[0034] The bottom block 11 is a solid protrusion and is integrated with the lower layer of the parallel plate 12. The anti-deviation column 13 of the parallel plate 12 is set in a vertical position. The pull block 15 on the top plate 14 is equipped with a sponge pad for direct contact with the hand. The auxiliary groove 16 and the pressing block 17 are each provided in two sets and are set in a symmetrical position on the top plate 14.

[0035] The assembly end 131 and the assembly frame 2 are shaped to match each other. The column 132 is solid and vertical, and the slider 134 is solid and protruding, which contacts the inner wall of the liquid nitrogen tank. The column 132 is connected to the top plate 14 and the edge of the parallel plate 12 by the splicing blocks 133 at the upper and lower ends.

[0036] The pressing block 17 is further provided with an insert block 171. The upper end of the insert block 171 is connected to a magnetic suction plate 172. A solid block 173 is provided on the upper layer of the magnetic suction plate 172, and a control groove 174 is opened on the edge of the solid block 173.

[0037] The insert block 171 is perpendicular to the magnetic suction plate 172, and the solid block 173 is parallel to the magnetic suction plate 172. The control groove 174 is a recessed hollow shape and is symmetrically opened on the left and right sides of the solid block 173.

[0038] The assembly end 131 is also provided with a contact layer 1311. A limit block 1312 is provided at the edge of the contact layer 1311. A restraining block 1313 is provided at the outer center of the limit block 1312. The center of the restraining block 1313 is penetrated by a slide rod 1314. A push block 1315 is provided at the upper end of the slide rod 1314 and a locking bolt 1316 is provided at the center. A clamping block 1317 is also connected to the lower end of the slide rod 1314.

[0039] The contact layer 1311 is parallel and contacts the assembly frame 2. The limiting block 1312 allows the slide rod 1314 to pass through vertically through the restraining block 1313. The clamping block 1317 at the lower end of the slide rod 1314 contacts the edge of the assembly frame 2.

[0040] The specific functions and operation procedures of this embodiment are as follows: In this invention, the sika deer embryo cryopreservation rack can be formed into a complete cryopreservation rack by auxiliary structure 1 and assembly frame 2, etc. The assembly frame 2 can be parallelly connected to multiple sets of placement trays 4 through corner connecting rods 3. Then, the length of the connecting rods 3 is used to maintain a safe distance, ensuring that the cryopreservation structure 5 can load the sika deer embryos and then enter the liquid nitrogen tank for freezing. For this purpose, the parallel plate 12 of the auxiliary structure 1 can cooperate with the bottom block 11 to allow the pull block 15 of the top plate 14 to be uniformly controlled after entering the liquid nitrogen tank, and the bottom block 11 is embedded. During the process of inserting the anti-deviation column 13 into the bottom position of the liquid nitrogen tank, it can directly contact the inner wall of the liquid nitrogen tank to prevent tilting. After the entire assembly is installed into the liquid nitrogen tank, the pressing block 17 can be embedded through the auxiliary groove 16 of the top plate 14. The weight of the pressing block 17 can prevent floating due to insufficient weight, thus improving stability during freezing. Subsequently, the column body 132 of the anti-deviation column 13 can be connected to the top plate 14 and the parallel plate 12 through the upper and lower splicing blocks 133, and then connected to the assembly frame 2 through the assembly end 131. When placed into the liquid nitrogen tank, it can contact the slider 134 to form a stable vertical freezing position, preventing tilting and improving the accuracy of embryo freezing. The solid block 173 of the pressing block 17 can be directly controlled by the operator through the edge control groove 174. After entering the auxiliary tank 16, it can be fixed by the lower magnetic suction plate 172 and the insert block 171, improving the stability during weight increase and preventing automatic detachment. Furthermore, the contact layer 1311 of the assembly end 131 can limit the assembly frame 2 through the limiting block 1312. The restraining block 1313 of the rear limiting block 1312 allows the slide bar 1314 to pass through vertically, so that when the upper push block 1315 of the slide bar 1314 is manually controlled, the height of the clamping block 1317 can be controlled. Finally, after the clamping block 1317 is clamped and contacted with the edge of the assembly frame 2, the push block 1315 can be positioned by the locking bolt 1316, which improves the firmness of the assembly and the ease of disassembly, avoids the instability of the assembly frame 2 caused by simple interlocking assembly, and further improves the stability when carrying sika deer embryos for freezing.

[0041] Example 2: Figures 6 to 7 As shown: This invention provides a sika deer embryo cryopreservation rack. Its structure includes a label ring 51 provided in the freezing structure 5, a positioning ring 52 provided on the inner wall of the label ring 51, a non-slip surface 53 provided on the center of the positioning ring 52, and a through groove 54 opened at the center position, through which the freezing tube 55 is positioned.

[0042] The label ring 51 and the positioning ring 52 are located at the same center point. The anti-slip surface 53 is provided with anti-slip texture. The through groove 54 is circular and opened vertically to allow the freezing tube 55 to pass through. The freezing tube 55 is "T" shaped.

[0043] The freezing tube 55 is also provided with a hand-held block 551. The lower end of the hand-held block 551 is connected to a cover plate 552. The lower end of the cover plate 552 is connected to a locking body 553. The locking body 553 is adapted to the position of the locking layer 554 and communicates with the freezing tank 556. The freezing tank 556 and the locking layer 554 are both located inside the tube body 555.

[0044] The cover plate 552 is connected to the locking layer 554 of the tube body 555 via the locking body 553 to form a stable "T"-shaped through-through groove 54.

[0045] The specific functions and operation procedures of this embodiment are as follows: In this invention, the positioning ring 52 of the freezing structure 5 can be accurately labeled with a tag ring 51. Then, the positioning ring 52 can be adapted to the freezing tube 55 through the anti-slip surface 53 at the center and the through groove 54. After the freezing tube 55 is driven by the hand block 551 to disengage the locking body 553 of the covering plate 552 from the locking layer 554 of the tube body 555, the sika deer embryos can be placed into the freezing tank 556. Then, the locking body 553 is reconnected to the locking layer 554, so that the covering plate 552 and the tube body 555 can form a "T" shape, which improves the perpendicularity with the positioning ring 52. At the same time, the sealing can prevent liquid nitrogen from entering the tube body 555 and directly contacting the embryos during the freezing process, ensuring the safety of the embryos during freezing. Meanwhile, the covering plate 552 can directly contact the anti-slip surface 53, and the anti-slip property can prevent loosening, improve the adaptation accuracy with the positioning ring 52, and facilitate subsequent handling.
