Description

Technical Field

[0001] This utility model relates to the field of veterinary medical device technology, specifically a multifunctional bovine live oocyte follicle fluid collection tube. Background Technology

[0002] Oocyte retrieval-in vitro embryo production (OPU-IVP) is a relatively new assisted reproductive technology compared to superovulation and in vivo embryo production (IVD). OPU-IVP is characterized by high efficiency, strong reproducibility, and minimal impact on donors. Therefore, in commercial embryo production, OPU-IVP is gradually replacing IVD and becoming a key method for expanding the breeding stock in cattle. During the OPU procedure, accurate collection of follicular fluid is crucial for subsequent IVP or related experimental requirements. However, existing collection tubes are mostly single-chamber structures (usually 50mL centrifuge tubes), leading to the forced mixing of different types of fluids, such as blood, follicular fluid of varying diameters, follicular cyst fluid, and flushing fluid from blocked tubes. This significantly impacts subsequent oocyte retrieval for IVP or other experimental needs. Therefore, frontline veterinarians urgently require a dedicated OPU collection device that can identify fluid properties in real time, supports classified collection, and has a simple and practical structure to improve oocyte retrieval efficiency and meet diverse experimental requirements.

[0003] Based on this, a multifunctional bovine live oocyte follicular fluid collection tube is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0026] The regulating component 2 includes a rotary valve core 21, which is rotatably connected to the inside of the tube cover 12. A sealing ring 22 is fixedly connected to the outer wall of the rotary valve core 21. The sealing ring 22 is slidably connected to a groove on the tube cover 12. The inner wall of the rotary valve core 21 is provided with a first interface and a second interface. A negative pressure pump rubber tube 25 is fixedly connected to the first interface, and a transparent silicone tube 26 is fixedly connected to the second interface.

[0027] In this embodiment, the adjusting component 2 can be used to adjust the follicular fluid, blood and cleaning fluid to enter different chambers respectively, avoiding cross-infection and facilitating the independent transfer of fluid from each chamber. The positioning component 3 can position the adjusting component 2, making the adjustment of the adjusting component 2 more precise and avoiding deviation.

[0028] In an optional embodiment, such as Figures 1-4 As shown, the transparent silicone tube 26 is made of medical-grade silicone and has an inner diameter of approximately 1.2 mm. Before performing live bovine oocyte retrieval, the negative pressure pump rubber tube 25 is connected to the external negative pressure pump, and the transparent silicone tube 26 is connected to the OPU oocyte retrieval needle.

[0029] In an optional embodiment, such as Figure 3 As shown, a knob 24 is fixedly connected to the top of the rotary valve core 21, and a fixed frame 23 is fixedly connected to the outer periphery of the top of the rotary valve core 21. A guide groove is provided on the fixed frame 23. By providing a guide groove on the fixed frame 23, the positioning block 32 will not deviate when it is squeezed and slid.

[0030] In an optional embodiment, such as Figure 2 As shown, the transparent tube 1 is divided into two, three or four independent collection chambers by the partition plate 11. Each independent chamber can be equipped with a label area 3A, 3B, 3C... The label content is letters, numbers or color blocks, so as to facilitate the differentiation of solutions within a certain period.

[0031] In an optional embodiment, such as Figure 2 As shown, the top of the partition plate 11 is level with or slightly lower than the top of the transparent tube 1, ensuring that the top of each collection chamber is completely open, thereby preventing the collection chamber from being closed and preventing liquid from entering.

[0032] In an optional embodiment, such as Figure 4 As shown, the positioning component 3 includes a mounting plate 31, a positioning block 32 fixedly connected to the side wall of the mounting plate 31, the positioning block 32 being inserted into a positioning groove on the fixed frame 23, a slider 33 fixedly connected to the bottom end of the mounting plate 31, the slider 33 being slidably connected to a groove on the tube cover 12, a guide rod 34 being sleeved inside the slider 33, one end of the guide rod 34 being fixedly connected to the inside of the groove, and a spring 35 being sleeved outside the guide rod 34, one end of the spring 35 being fixedly connected to the side wall of the slider 33, and the other end being fixedly connected to the inside of the groove. When the knob 24 is rotated, the fixed frame 23 is driven to rotate synchronously, causing the fixed frame 23 to press against the positioning block 32, causing the positioning block 32 to slide in the guide groove on the fixed frame 23. When it reaches the designated position, under the action of the spring 35, the slider 33 is driven to slide on the outer wall of the guide rod 34, causing the slider 33 to drive the mounting plate 31 and the positioning block 32 to move synchronously, so that the positioning block 32 is inserted into the positioning groove on the fixed frame 23, thereby completing the positioning.

[0033] In an optional embodiment, such as Figures 1-4 As shown, the transparent tube 1, the tube cap 12, and the rotary valve core 21 are made of medical-grade polypropylene material to ensure the safety of the product during use.

[0034] The above embodiment discloses a multifunctional bovine live oocyte follicular fluid collection tube. In use, the negative pressure pump rubber tube 25 is connected to an external negative pressure pump, and the transparent silicone tube 26 is connected to the OPU oocyte retrieval needle. Then, the knob 24 is turned, causing the rotary valve core 21 to rotate synchronously. The rotary valve core 21 drives the transparent silicone tube 26 and the negative pressure pump rubber tube 25 to rotate. When rotated to the designated position, under the action of the spring 35, the slider 33 slides on the outer wall of the guide rod 34, causing the slider 33 to drive the mounting plate 31 and the positioning block 32 to move synchronously. The positioning block 32 then engages with the positioning groove on the fixing frame 23, thus completing the positioning. At this time, the transparent silicone tube 26 is aligned with the separated chamber 3A. The negative pressure pump is then started to begin oocyte retrieval. During oocyte retrieval, the pale yellow follicular fluid falls directly into the chamber 3A through the transparent silicone tube 26. When red blood is observed inside the transparent silicone tube 26 during oocyte retrieval... Rotate knob 24 120° to rotate transparent silicone tube 26 synchronously. When positioning block 32 is inserted into positioning slot again, stop rotating. At this time, transparent silicone tube 26 is aligned with chamber 3B, allowing subsequent blood to flow into chamber 3B and avoiding contamination of follicular fluid in chamber 3A. When transparent silicone tube 26 is blocked, rotate knob 24 to rotate transparent silicone tube 26 synchronously, aligning transparent silicone tube 26 with chamber 3C. Then, inject 10mL of oocyte retrieval fluid with a syringe to flush the tube. Residual follicular fluid is collected back into chamber 3C. After oocyte retrieval, the fluid from each chamber is independently transferred to a culture dish for processing. In summary, the adjustment component 2 can be used to adjust follicular fluid, blood, and washing fluid to enter different chambers separately, avoiding cross-infection and facilitating the independent transfer of fluid from each chamber. The positioning component 3 can be used to position the adjustment component 2, making the adjustment more precise and avoiding deviations.
