Description

Technical Field

[0001] This utility model relates to the field of frozen sperm and embryo thawing technology, and in particular to a frozen sperm and embryo constant temperature thawing device. Background Technology

[0002] Artificial insemination and embryo transfer techniques for animals are now widely used. The semen and frozen embryos used are stored in liquid nitrogen at -196°C and must be thawed before use. The thawing water temperature is usually between 36°C and 40°C, which necessitates the use of a constant-temperature thawing device. In the existing technology, most traditional constant temperature thawing devices are simply thawing boxes, heating blocks and placement racks used together. With this setup, after the test tubes containing semen and frozen embryos are placed into the placement rack, the rack needs to be manually removed and placed. The removal and placement process is inconvenient and wastes time and energy. At the same time, the placement racks are mostly fixed structures, which are not convenient for placing test tubes of different lengths, reducing the practicality and applicability of the constant temperature thawing device.

[0017] To accommodate test tubes of different lengths, a fixed cylinder 12 is fixedly installed on the upper surface of the base plate 9, and a rotating cylinder 13 is rotatably connected to the upper surface of the top plate 10. The rotating cylinder 13 passes through the upper surface of the top plate 10 and is fitted onto the outer surface of the fixed cylinder 12. A rotating block 14 is fixedly installed at the top of the rotating cylinder 13, and a second lead screw 15 is fixedly installed on the inner wall of the rotating cylinder 13.

A telescopic plate 18 that plugs into the fixed sleeve 16 is fixedly installed at the bottom end of the fixed block 17. A limit block 19 is fixedly installed at the bottom end of the telescopic plate 18, and a limit groove that matches the limit block 19 is opened through the outer wall of the fixed sleeve 16.

[0018] By setting up a defrosting chamber 1, a constant temperature heating block 2, a drain pipe 3, a lifting frame 4, a groove 5, a servo motor 6, a first lead screw 7, a sliding rod 8, a base plate 9, a top plate 10, a placement seat 11, a fixing cylinder 12, a rotating cylinder 13, a rotating block 14, a second lead screw 15, a fixing sleeve 16, a fixing block 17, a telescopic plate 18, and a limiting block 19, the device achieves convenient and quick access to the placement rack and the ability to place test tubes of different lengths. This improves the setup of existing constant temperature defrosting devices, allowing for rapid access to the placement rack and test tubes, saving time and effort. Furthermore, the length of the placement rack can be adjusted to accommodate test tubes of different lengths, enhancing the practicality and applicability of the constant temperature defrosting device.

[0019] A support assembly is provided below the top plate 10. The support assembly includes a lifting plate 20, which is located below the top plate 10. A support cylinder 21 is installed through the upper surface of the lifting plate 20. Four sliding plates 22 that are in contact with the fixing blocks 17 are fixedly installed on the side wall of the lifting plate 20. A locking block 23 is fixedly installed on the side wall of each of the two sliding plates 22. A slot 24 is opened on the side wall of each of the two fixing blocks 17. The locking block 23 and the slot 24 are both T-shaped. The inner wall of the locking block 23 and the slot 24 are slidably connected. Rubber blocks 25 are fixedly installed on the side wall of the other two sliding plates 22. Positioning grooves that are adapted to the rubber blocks 25 are opened on the side wall of the other two fixing blocks 17.

[0020] By setting up a lifting plate 20, a support cylinder 21, a sliding plate 22, a locking block 23, a locking groove 24, and a rubber block 25, the function of supporting the test tube is realized. By using the movable lifting plate 20 in conjunction with the support cylinder 21 to support the test tube, the stability of the test tube placement is improved after the test tube passes through the support cylinder 21, preventing the test tube from shaking inside the placement rack and improving the safety of the constant temperature defrosting device.

[0021] Working principle: When using the constant temperature thawing device to thaw semen and frozen embryos, first place the test tubes containing semen and frozen embryos into the rack. Add an appropriate amount of water to the inside of the thawing chamber 1. Then, use the constant temperature heating block 2 to heat the water to a suitable temperature. Next, adjust the distance between the bottom plate 9 and the top plate 10 according to the length of the test tubes. Rotate the rotating block 14. When the rotating block 14 rotates, it drives the rotating cylinder 13 to rotate on the outer upper surface of the fixed cylinder 12, simultaneously causing the second lead screw 15 to rotate inside the fixed cylinder 12. When the second lead screw 15 rotates, it drives the fixed cylinder 12 to move through the threaded groove. Under the action of the fixed sleeve 16, the fixed block 17 and the telescopic plate 18, the bottom plate 9 and the top plate 10 move away from each other or move closer to each other. The rotating cylinder 13 slides on the outer surface of the fixed cylinder 12, the telescopic plate 18 slides inside the fixed sleeve 16, and the limiting block 19 slides inside the limiting groove. When the distance between the bottom plate 9 and the top plate 10 reaches a suitable distance, the rotating block 14 stops rotating to fix the distance between the bottom plate 9 and the top plate 10.

[0022] Next, the test tube containing semen and frozen embryos is passed through the placement slot through the top plate 10, through the support cylinder 21 through the lifting plate 20, and placed inside the placement seat 11 on the bottom plate 9. Then, the lifting plate 20 is pulled down, causing the lifting plate 20 to slide along the side wall of the fixing block 17, the locking block 23 to slide inside the locking groove 24, and the support cylinder 21 to slide on the outer surface of the test tube. When the lifting plate 20 slides to the appropriate position, the rubber block 25 is inserted into the positioning groove to fix the position of the lifting plate 20, and the support cylinder 21 supports the test tube.

[0023] Next, the rack containing the test tubes is placed inside the thawing chamber 1, positioned above the lifting frame 4. Then, the servo motor 6 is started. When the servo motor 6 runs, it drives the first lead screw 7 to rotate inside the groove 5. As the first lead screw 7 rotates, it moves the lifting frame 4. Under the action of the sliding rod 8, the lifting frame 4 slides downwards inside the thawing chamber 1 along the outer surface of the first lead screw 7 and the sliding rod 8, simultaneously causing the rack to descend into the thawing chamber 1. This causes the rack to carry the test tubes into the heated water. Once the rack and test tubes have descended to the appropriate depth, the servo motor 6 is stopped, fixing the position of the rack and test tubes, thus thawing the semen and frozen embryos. After the semen and frozen embryos have thawed, the above operation is reversed to remove the rack and test tubes from the thawing chamber 1. After removing the rack and test tubes from the thawing chamber 1, the test tubes are then removed from the rack.

[0024] 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.
