Description

Technical Field

[0001] This invention relates to the field of frozen semen preservation technology, specifically to a device for thawing frozen semen used in breeding. Background Technology

[0002] Frozen semen technology for livestock allows artificial insemination to be carried out without time or geographical limitations, enabling mating to occur on non-working days or in remote locations, greatly improving the flexibility and efficiency of breeding. Furthermore, the long-term preservation characteristics of frozen semen mean that the semen of superior breeding males can be used whenever needed, avoiding resource waste caused by the limited lifespan of breeding males. Frozen semen thawing refers to rapidly thawing frozen semen at a specific temperature before insemination to restore sperm viability. There are two main thawing methods: dry thawing and wet thawing. Dry thawing involves directly immersing the frozen semen in a container at a specific temperature; wet thawing involves immersing the frozen semen in a thawing solution.

[0003] In existing technologies, frozen semen thawing equipment for breeding involves placing the frozen semen reagent tubing inside a water bath for thawing. However, when thawing multiple frozen semen reagent tubing, this requires frequent replacement of the thawing solution, making the operation cumbersome. Furthermore, heating can cause different temperatures of the thawing solution in different areas of the water bath. On the other hand, conventional frozen semen reagent tubing needs to be removed from the water bath after thawing and then injected into the diluent tank. This process causes changes in the ambient temperature of the frozen semen reagent tubing, resulting in insufficient environmental stability. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a frozen semen thawing device for insemination, thereby solving the problems mentioned in the background section. This invention circulates the thawing solution through a circulation mechanism, controlling the temperature during the flow process. This simultaneously provides a constant temperature effect to the frozen semen reagent tubing and the diluent tank, eliminating the need for frequent thawing solution replacements and ensuring a more stable temperature. Furthermore, the frozen semen reagent tubing does not need to be removed after thawing; a transfer mechanism directly delivers the thawed semen to the diluent tank, ensuring the frozen semen reagent tubing remains under a completely constant temperature environment and improving the thawing success rate.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a thawing device for insemination, comprising a thawing device body and frozen semen reagent tubing. The thawing device body includes a thawing chamber, a circulation mechanism, a connector assembly, and a transfer mechanism. A water bath channel is formed on the inner wall of the thawing chamber. A circulation mechanism is installed in the middle of the water bath channel. The interior of the water bath channel is divided into thawing channels. A transfer mechanism is inserted into the bottom outer side of the thawing channels. A diluent tank is inserted into the interior of the water bath channel. The end of the transfer mechanism is inserted into the interior of the diluent tank. The connector assembly is embedded into the interior of the thawing channels. The frozen semen reagent tubing is embedded below the connector assembly. Multiple frozen semen reagent tubings are frozen and thawed after being installed on the connector assembly. A cover plate is hinged to the rear end of the thawing chamber. A clamping block is attached to the inner wall of the water bath channel. The clamping block is used to clamp and fix the diluent tank. A gap is provided between the side of the diluent tank and the inner wall of the water bath channel.

[0006] Furthermore, the two ends of the defrosting channel are integrally formed with a first partition and a second partition, respectively. The bottom inner side of the first partition is connected to a bottom flow channel. Multiple heat-insulating sheets are inserted inside the defrosting channel, and the bottom inner side of the defrosting channel is connected to a diffusion channel.

[0007] Furthermore, one end of the diffusion channel is connected to the interior of the bottom flow channel, the surface of the second partition is provided with a top flow channel notch, and the bottom of the top flow channel notch is flush with the top of the heat-insulating sheet, and a gap is provided between the bottom of the heat-insulating sheet and the bottom of the inner wall of the defrosting channel.

[0008] Furthermore, the transfer mechanism includes a convex plate and a push plate. The convex plate is integrally formed on the surface of the thawing channel. Multiple sealing sleeves are formed on the surface of the convex plate. Insertion needles are inserted into the interior of the sealing sleeves. The rear end of the insertion needles is connected to a diversion tube.

[0009] Furthermore, the rear end of the diverting capillary is connected to a collecting pipe, one end of which is connected to a conveying pipe. The conveying pipe extends from the top of the diluent tank into the inside. A push plate is attached to the rear end of the insertion needle, and the end of each insertion needle is aligned with the bottom middle area of ​​two adjacent heat-insulating sheets.

[0010] Furthermore, the plug-in assembly includes a pressing plate, a pestle, and a lifting plate. The pressing plate has upright plates welded to both sides, and a magnetic suction plate is attached to the top inner side of the upright plate. The two ends of the lifting plate are attached to the bottom of the magnetic suction plate, and a pull rod is installed on the surface of the lifting plate.

[0011] Furthermore, multiple pestles are inserted into the bottom of the lifting plate, and multiple adsorption sleeves are inserted into the bottom of the pressing plate. A sponge collar is attached to the bottom of the inner wall of each adsorption sleeve, and the top of the frozen semen reagent tube is inserted upward from the bottom of the adsorption sleeve.

[0012] Furthermore, the sponge collar is fitted onto the top surface area of ​​the frozen sperm reagent tube, and the sponge collar is fixedly connected to the surface of the frozen sperm reagent tube after being frozen by the absorbed water. The pestle moves down and simultaneously embeds into the interior of each corresponding frozen sperm reagent tube. The insertion needle is used to insert into the bottom area of ​​each frozen sperm reagent tube.

[0013] Furthermore, the circulation mechanism includes a circulation pump, an extraction pipe, and a circulation pipe. A third partition is integrally formed on the inner side of one end of the water bath channel. The circulation pump is screwed into the interior of the defrosting box. An extraction pipe and a circulation pipe are respectively inserted into both ends of the circulation pump.

[0014] Furthermore, the ends of the extraction pipe and the circulation pipe are respectively connected to the two sides of the third partition. An electric heating sleeve is installed on the surface of the extraction pipe, and a temperature sensing module is installed on the surface of the circulation pipe.

[0015] The beneficial effects of this invention are:

[0016] 1. This frozen semen thawing device for breeding uses a circulation mechanism to circulate the thawing solution and control the temperature while it is in a flowing state. It also provides a constant temperature effect to the frozen semen reagent tubing and the diluent tank, eliminating the need for frequent replacement of the thawing solution and ensuring a more constant temperature.

[0017] 2. This frozen semen thawing device for breeding has thawing channels divided into water bath channels. With the help of the diffusion structure at the bottom of the thawing channels, the constant temperature thawing solution can be evenly flowed from the bottom to the top of each frozen semen reagent tube, so that each frozen semen reagent tube is in contact with the thawing solution at a fixed temperature. Therefore, multiple frozen semen reagent tubes can be thawed at the same time, and the problem of inconsistent thawing effect on frozen semen reagent tubes at different positions due to sequential thawing can be avoided.

[0018] 3. After the frozen semen reagent tubing of this insemination frozen semen thawing device is thawed, it does not need to be removed. With the help of the transfer mechanism, the thawed semen can be directly transported to the diluent tank, ensuring that the frozen semen reagent tubing is always in a completely constant temperature environment, thereby improving the success rate of thawing.

[0019] 4. The plug-in assembly used in this invention can directly install multiple frozen sperm reagent tubes and simultaneously perform the freezing and thawing processes. During freezing, the water absorbed in the sponge collar freezes to fix each frozen sperm reagent tube. After thawing, each frozen sperm reagent tube can be removed and a new frozen sperm reagent tube can be placed for freezing and reuse. Therefore, it can be recycled and multiple frozen sperm reagent tubes can be thawed conveniently, making the thawing process of multiple frozen sperm reagent tubes more convenient.

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] Please see Figures 1 to 7 The present invention provides the following technical solution: a thawing device for frozen semen used in breeding, comprising a thawing device body and a frozen semen reagent tubing 13. The thawing device body includes a thawing chamber 1, a circulation mechanism 4, a connector 3, and a transfer mechanism 5. A water bath channel 15 is formed on the inner wall of the thawing chamber 1. The circulation mechanism 4 is installed in the middle of the water bath channel 15. The interior of the water bath channel 15 is divided into thawing channels 16. The transfer mechanism 5 is inserted into the outer bottom of the thawing channels 16. A diluent tank 27 is inserted into the interior of the water bath channel 15. The end of the transfer mechanism 5 is inserted into the interior of the diluent tank 27. The insertion assembly 3 is embedded into the interior of the thawing channel 16. The frozen semen reagent tubes 13 are all embedded below the insertion assembly 3. Multiple frozen semen reagent tubes 13 are frozen and thawed after being installed on the insertion assembly 3. The rear end of the thawing chamber 1 is hinged with a cover plate 2. A locking block 26 is attached to the inner wall of the water bath channel 15. The locking block 26 is used to clamp and fix the diluent tank 27, and a gap is provided between the side of the diluent tank 27 and the inner wall of the water bath channel 15. This frozen semen thawing device for insemination can place multiple frozen semen reagent tubes 13 containing frozen semen into the interior of the thawing chamber 1, and complete the thawing process by heating with a water bath. The process of transporting the semen to the interior of the diluent tank 27 is also completed inside the thawing chamber 1.

[0030] In use, the thawing solution is first injected into the water bath channel 15. Then, the heating unit in the circulation mechanism 4 is activated to heat the thawing solution until it reaches the temperature required for thawing the frozen semen. Then, the connector 3, which has multiple frozen semen reagent tubes 13 inserted into it, is removed from the inside of the freezing equipment and inserted into the thawing channel 16 in the water bath channel 15. It is left to stand until the thawing process is completed. Throughout the thawing process, the circulation mechanism 4 controls the thawing solution to maintain a flow along the water bath channel 15. After thawing, the semen inside each frozen semen reagent tube 13 is punctured directly through the inner transfer mechanism 5. With the push of the connector 3, the frozen semen can be directly transferred to the diluent tank 27 already placed in the water bath channel 15, thus completing the entire thawing process.

[0031] In this embodiment, the defrosting channel 16 has a first partition 18 and a second partition 19 integrally formed at both ends. The bottom inner side of the first partition 18 is connected to a bottom flow channel 21. Multiple heat-insulating sheets 24 are inserted inside the defrosting channel 16, and a diffusion channel 23 is connected to the bottom inner side of the defrosting channel 16. One end of the diffusion channel 23 is connected to the interior of the bottom flow channel 21. The surface of the second partition 19 has a top flow notch 20, and the bottom of the top flow notch 20 is flush with the top of the heat-insulating sheet 24. A gap is provided between the bottom of the heat-insulating sheet 24 and the bottom of the inner wall of the defrosting channel 16. The water bath channel 15 is divided into a thawing channel 16. With the help of the diffusion structure at the bottom of the thawing channel 16, the constant temperature thawing liquid can flow evenly from the bottom to the top of each frozen sperm reagent tube 13, so that each frozen sperm reagent tube 13 is in contact with the thawing liquid at a fixed temperature. Therefore, multiple frozen sperm reagent tubes 13 can be thawed at the same time, and the problem of inconsistent thawing effect on frozen sperm reagent tubes 13 at different positions due to the sequential order is avoided.

[0032] Specifically, when the plug-in assembly 3, along with multiple frozen sperm reagent tubes 13, is placed inside the thawing channel 16, it will abut against the pressing plate 6 of the plug-in assembly 3 via the top of the water bath channel 15. Each frozen sperm reagent tube 13 is then inserted between two adjacent heat-insulating sheets 24. At this point, the frozen sperm reagent tubes 13 can be immersed in the water bath for heating and thawing. During the thawing process, the thawing fluid inside the water bath channel 15 is driven by the circulation mechanism 4 to form a flowing state. The thawing fluid at the bottom of the first partition 18 is blocked by the first partition 18, allowing it to flow only from the bottom. The liquid flows out from the bottom channel 21 of the part, enters the bottom area of ​​the thawing channel 16 along the connecting channel 22 and the diffusion channel 23, and flows in from the bottom area of ​​each heat-insulating sheet 24 at the same time. Therefore, the bottom of each frozen sperm reagent tube 13 can simultaneously contact the flowing and diffused thawing liquid. Finally, the thawing liquid flowing into the thawing channel 16 continues to be discharged from the top channel notch 20 on the second partition 19 towards the water bath channel 15 at the other end, and heats the diluent tank 27. The whole process ensures that the frozen sperm reagent tubes 13 can be heated synchronously.

[0033] In this embodiment, the transfer mechanism 5 includes a convex plate 29 and a pusher plate 32. The convex plate 29 is integrally formed on the surface of the thawing channel 16. Multiple sealing sleeves 30 are formed on the surface of the convex plate 29. Insertion needles 31 are inserted into the interior of each sealing sleeve 30. The rear end of each insertion needle 31 is connected to a diverting capillary tube 33. The rear end of the diverting capillary tube 33 is connected to a collecting pipe 34. One end of the collecting pipe 34 is connected to a conveying pipe 28, which extends from the top of the diluent tank 27 to the inside. The pusher plate 32 is attached to the rear end of each insertion needle 31. The end of each insertion needle 31 is aligned with the bottom center area of ​​two adjacent heat-resistant sheets 24. After thawing, there is no need to remove the needle; the thawed semen can be directly conveyed to the diluent tank 27 using the transfer mechanism 5, ensuring that the frozen semen reagent tubing 13 remains in a completely constant temperature environment, thus improving the thawing success rate.

[0034] Specifically, after the water bath heating and thawing is completed, by pushing the push plate 32, each insertion needle 31 is inserted into the bottom of the thawed frozen semen reagent tube 13. Then, by pressing the top pull rod 10 and cooperating with the pestle 11, the thawed semen portion inside each frozen semen reagent tube 13 can be pushed along the insertion needle 31 into the inside of the diversion tube 33, and then pushed along the collection pipe 34 and the delivery pipe 28 into the inside of the diluent tank 27. By repeatedly pulling the pull rod 10, the semen mixed diluent accumulated in the diversion tube, the inside of the frozen semen reagent tube 13, the collection pipe 34 and the delivery pipe 28 can be repeatedly transported into the inside of the diluent tank 27 in conjunction with the diluent.

[0035] In this embodiment, the insertion assembly 3 includes a pressing plate 6, a pestle 11, and a lifting plate 9. Upright plates 7 are welded to both sides of the pressing plate 6. A magnetic suction plate 8 is attached to the top inner side of the upright plate 7. Both ends of the lifting plate 9 are attached to the bottom of the magnetic suction plate 8. A pull rod 10 is installed on the surface of the lifting plate 9. Multiple pestles 11 are inserted into the bottom of the lifting plate 9, and multiple adsorption sleeves 12 are inserted into the bottom of the pressing plate 6. A sponge collar 14 is attached to the bottom of the inner wall of each adsorption sleeve 12. The top of the frozen sperm reagent tube 13 extends upwards from the bottom of the adsorption sleeve 12. The sponge collar 14 is fitted onto the top surface area of ​​the frozen sperm reagent tube 13, and after the adsorbed water is frozen, the sponge collar 14 is fixedly connected to the surface of the frozen sperm reagent tube 13. The pestles 11 move downwards and simultaneously embed into the interior of each corresponding frozen sperm reagent tube 13. The insertion needle 31 is used to insert into the bottom area of ​​each frozen sperm reagent tube 13. The plug-in assembly 3 can directly install multiple frozen sperm reagent tubes 13 and simultaneously perform freezing and thawing processes. During freezing, the water absorbed in the sponge collar 14 freezes and fixes each frozen sperm reagent tube 13. After thawing, each frozen sperm reagent tube 13 can be removed and a new frozen sperm reagent tube 13 can be placed for freezing and reuse. Therefore, it can be recycled and can also facilitate the thawing of multiple frozen sperm reagent tubes 13, making the thawing process of multiple frozen sperm reagent tubes 13 more convenient.

[0036] Specifically, the top of the frozen semen reagent tube 13 containing the collected semen is inserted into the adsorption sleeve 12, and the water-absorbing sponge ring 14 is brought into contact with the surface of the frozen semen reagent tube 13. In the initial state, pulling the lever 10 will attract the magnetic plates 8 at both ends of the lifting device. Then, the entire insertion assembly 3 and the inserted frozen semen reagent tube 13 can be placed in the freezing equipment in a horizontal or inclined position. After freezing, the sponge ring 14 can be fixedly connected to the frozen semen reagent tube 13 by the freezing phenomenon. When the above thawing process is carried out, the insertion assembly 3 can be taken out directly by pulling the lever 10. After the above thawing process, the freezing phenomenon of the sponge ring 14 can be removed at the same time. Therefore, each frozen semen reagent tube 13 can be easily removed after use.

[0037] In this embodiment, the circulation mechanism 4 includes a circulation pump 17, an extraction pipe 36, and a circulation pipe 38. A third partition 35 is integrally formed on the inner side of one end of the water bath channel 15. The circulation pump 17 is screwed into the interior of the thawing chamber 1, and the extraction pipe 36 and circulation pipe 38 are respectively inserted into both ends of the circulation pump 17. The ends of the extraction pipe 36 and circulation pipe 38 are respectively connected to the two sides of the third partition 35. An electric heating sleeve 37 is installed on the surface of the extraction pipe 36, and a temperature sensing module 39 is installed on the surface of the circulation pipe 38. The circulation mechanism 4 circulates the thawing fluid and controls the temperature during the flow, simultaneously providing a constant temperature effect to the frozen sperm reagent tubing 13 and the diluent tank 27. This eliminates the need for frequent thawing fluid replacement and ensures a more constant temperature. Specifically, by starting the circulation pump 17, the thawing fluid inside the water bath channel 15 can be extracted through the extraction pipe 36. The fluid is then repeatedly heated in the extraction pipe 36 with the help of the electric heating sleeve 37. The fluid is then transported back into the water bath channel 15 through the circulation pipe 38. The temperature of this portion of the thawing fluid is measured by the temperature sensing module 39, and the heating temperature of the electric heating sleeve 37 is controlled based on the measurement data, so that the thawing fluid inside the entire water bath channel 15 always remains in a flowing state and always at a constant temperature.

[0038] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

[0039] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
