As shown in fig. 4 and 5, a first accommodating chamber 101 for storing embryos and a second accommodating chamber 102 for storing liquid nitrogen are provided in the case 100, the first accommodating chamber 101 is provided in the center of the case 100, and the second accommodating chamber 102 surrounds the first accommodating chamber 101 from the side and the bottom.

The top of the second accommodating cavity 102 is provided with a plurality of top openings 103 which are oppositely arranged, and the top openings 103 are provided with nitrogen guide frames 300. As shown in fig. 5-7, the nitrogen guide frame 300 is composed of a plurality of tube bodies 301, two ends of the tube bodies 301 are provided with connectors 302 matched with the top openings 103, and the bottom of the tube bodies 301 is provided with a guide opening 303 arranged downwards. The liquid nitrogen in the second chamber 102 will volatilize during the transfer process, and the volatilized nitrogen will still have a lower temperature for cryopreservation of the embryo top. The volatilized cooler nitrogen gas enters the pipe body 301 from the top opening 103 through the joint 302 and moves downward into the first accommodation chamber 101 by the guide port 303. The nitrogen guide 300 can cool the embryo in the first accommodating chamber 101 from above, thereby cooling the embryo at all angles and improving the accommodating effect of the embryo. The top of the nitrogen guide frame 300 is provided with a connecting rod 304 for fixedly connecting each pipe body 301, and the connecting rod 304 is provided with a handle 305. When the nitrogen guide frame 300 is used, the nitrogen guide frame 300 can be quickly removed through the handle 305, and meanwhile, the handle 305 can also prevent the hands of an operator from being in contact with a low-temperature environment to cause frostbite.

As shown in fig. 5, the thermal insulation barrier 400 is disposed in both the case 100 and the folder 200. The heat-insulating barrier 400 can ensure the temperature in the case 100 and reduce the heat exchange with the outside.

The elastic sheet 502 is arranged in an arch shape, the top is fixedly connected with the supporting plate 501, and the elastic sheet 502 can absorb shock of the embryo in the first accommodating cavity 101 by means of self elasticity, so that damage of the embryo due to collision is avoided. Meanwhile, the elastic piece 502 is made of metal, so that the low-temperature condition in the first accommodating cavity 101 can be adapted.

As shown in fig. 8 and 5, an embryo box storage member 600 is provided in the first accommodation chamber 101, and the embryo box storage member 600 includes a receiving portion 601 and a handle 602. As can be seen in fig. 5, the handle 602 is fixedly connected to the accommodating portion 601 and extends upward out of the first accommodating cavity 101. The embryo box storage member 600 can facilitate the storage and taking of the embryo, and when the embryo needs to be taken out, the embryo can be quickly taken out by directly pulling the handle 602 above the first accommodating chamber 101.

As shown in fig. 4 and 5, the second accommodation chamber 102 has a liquid nitrogen inlet 104 at the top and a residual liquid outlet 105 at the bottom. Valves are provided on both the liquid nitrogen inlet 104 and the raffinate outlet 105, which are conventional and will not be further described herein.
