[0001] This utility model relates to the field of transportation device technology, specifically to an oocyte transportation device. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] With the in-depth research and commercial application of embryo engineering technology, the demand for oocytes from high-quality female livestock is increasing day by day. Since animal breeding bases are often far away from laboratories, experimental samples need to be transported back to the laboratory over a long period of time. Oocytes are affected by temperature and the stability of cell culture plates, which reduces their cell development capacity.

[0004] Therefore, companies design various transport containers, such as the oocyte and embryo transport device with announcement number CN205676484 U. This device connects the frame to the insulated box with elastic ropes. The frame is suspended, so when the culture plate box is placed on it for transport, it can play a damping role, reduce the vibration amplitude, and can naturally sway with the operation.

[0005] While the aforementioned transport box can ensure the stability of the cell culture plates and maintain the temperature of the plates inside, the following technical problems still exist during use:

[0006] Cell culture plate cassettes come in various sizes, but the frame size that holds them is fixed, which cannot accommodate cell culture plate cassettes of different sizes. The existing frame size for holding culture plate cassettes has poor adaptability. Utility Model Content

[0008] To achieve the above objectives, this utility model proposes an oocyte transport device, comprising a first box, a second box fixedly installed inside the first box, a carbon dioxide storage bottle disposed on the side wall of the first box, the carbon dioxide storage bottle being connected to the second box via a gas supply pipe, a plurality of heating tubes fixed on the side wall of the second box, a pair of sliding grooves disposed on the bottom wall of the second box along the diagonal length of the bottom wall of the second box, a guide rod fixedly disposed within the sliding groove, an L-shaped sliding plate slidably disposed on the guide rod, a spring fixedly disposed between the sliding plate and the side wall of the sliding groove, and a culture plate box being clamped between the L-shaped sliding plates.

[0009] A further configuration is provided, wherein a slide rod is fixedly installed at the bottom of the L-shaped slide, and a circular hole is formed in the center of the slide rod, through which a guide rod is disposed.

[0010] Further configuration includes an L-shaped groove on the side wall of the slide rail, with L-shaped sliders fixedly installed on both sides of the slide rod.

[0011] A further configuration is that the L-shaped groove is arranged along the length direction of the slide groove, and the slide rod is slidably disposed in the L-shaped groove via the L-shaped slider.

[0012] A second cover is further configured to be movable on the top of the second housing.

[0013] Further configuration involves the gas delivery tube penetrating the second box cover, with the gas delivery tube pointing towards the culture plate box.

[0014] Further configuration: the heating element is connected to a power source, the power source provides power to the heating element, and the heating element is located on the side wall of the second housing.

[0015] Further configured, a first box cover is movably mounted on the top of the first box.

[0016] Further configuration: the culture plate box is a rectangular box, and the two outer right-angled sides on the diagonal of the culture plate box are respectively set inside the two inner corners of the L-shaped slide.

[0017] A further configuration is provided, wherein a humidifier is fixedly installed on the top of the second housing.

[0018] The beneficial effects of one or more of the above technical solutions:

The guide rod 6 is set through the circular hole 71. The diameter of the circular hole 71 is larger than the diameter of the slide rod 74, so that the L-shaped slide plate 7 can move along the length direction of the guide rod 6. At the same time, the side wall of the slide groove 5 is opened with an L-shaped groove 51. L-shaped sliders 73 are fixedly installed on both sides of the slide rod 74, so that the slide rod 74 can be stopped at the upper limit in the length direction of the guide rod 6.

[0036] The L-shaped groove 51 is set along the length of the slide groove 5. The slide rod 74 is slidably set in the L-shaped groove 51 through the L-shaped slider 73. The L-shaped groove 51 and the L-shaped slider 73 are set to further improve the stability of the L-shaped slide plate 7 and prevent the L-shaped slide plate 7 from shifting during the adjustment process.

[0037] The first box 1 is movably provided with a first box cover 11 on the top. The second box 2 can be operated by opening the box cover, while preventing the first box 1 from being contaminated.
