[0027] The specific embodiment of the present embodiment will be described below with reference to the drawings.
[0028] Referring to Figure 1 , Figure 2 and Figure 3 , the utility model discloses an animal oocyte preservation device, including base 1, main support rod 2, vice support rod 3, nylon ring 4 and nylon grid 6, a nylon ring 4 can place multiple oocytes, generally is placed 5, the nylon ring 4 is oval type, and the short diameter of nylon ring 4 is 0.35mm, when dropping the cell, for example, a bovine oocyte diameter is 0.15mm, after 5 oocytes drop, the oocyte is maintained on the nylon ring 4 through the surface tension of the oocyte liquid and forms the liquid film, the base 1 top is fixedly installed main support rod 2, and the main support rod 2 top is provided with a plurality of vice support rods 3, and the vice support rod 3 tail end is provided with a plurality of nylon rings 4, and one base 1 can be provided with 5-10 vice support rods, and the embodiment selects 3 vice support rods, and simultaneously drops multiple groups of oocytes, which improves the oocyte preservation efficiency to a certain extent, and the central axis of the nylon ring 4 is parallel to the central axis of the main support rod 2, and the nylon ring 4 lower portion is fixedly provided with the nylon grid 6.
[0029] The base 1 is integrally arranged with the main support rod 2, and the main support rod 2 is welded to the top of the base 1, compared with the detachable magnetic support, the integrally arranged base 1 and main support rod 2 avoid falling off during the transfer process of the base 1.
[0030] The base 1 is provided with a ladder groove 7, the first magnetic ring 8 is arranged on the ladder groove 7, the bottle cap 9 is arranged corresponding to the ladder groove 7, the second magnetic ring 10 is fixedly arranged on the inner wall of the bottle cap 9, and the first magnetic ring 8 and the second magnetic ring 10 are adsorbed to ensure that the bottle cap 9 is stably fixed on the ladder groove 7.
[0031] The main support rod 2 and the vice support rod 3 are integrally arranged, and the vice support rod 3 is welded to the top of the main support rod 2.
[0032] An L-shaped rod 5 is fixedly installed at the end of the auxiliary support rod 3. The L-shaped rod 5 is made of metal. The end of the L-shaped rod 5 is fixedly installed to the side wall of the nylon ring 4. The L-shaped rod 5 is set to ensure that the central axis of the nylon ring 4 is perpendicular to the working platform. The L-shaped rod 5 and the nylon ring 4 are welded together.
[0033] The nylon mesh 6 includes interlaced arc-shaped nylon lines. The interlaced arc-shaped nylon lines catch the dripping oocytes, further reducing the risk of oocyte loss due to the failure of a single nylon loop to form a proper liquid film.
[0034] The inner diameter of the bottle cap 9 is larger than the outer diameter of the stepped groove 7. When the bottle cap 9 needs to be installed, the bottle cap 9 is placed upside down on the base 1.
