Description

Technical Field

[0001] The utility model relates to the technical field of semen preservation, in particular to a medium preservation device for low-temperature preservation of semen. Background Art

[0002] Huyang is a unique sheep breed in my country and one of the few white lambskin and multi-lamb sheep breeds in the world. Huyang has the advantages of fast growth, early maturity, estrus in all seasons, high multiple birth rate, tender and delicious meat, and light smell. In order to increase the fertilization rate when raised in captivity, the semen of rams is collected for frozen storage, so antifreeze substances are needed to store the semen of rams. For this reason, people have screened out the most suitable antifreeze substances for semen storage through experiments. These substances are placed in reagent tubes, and then the reagent tubes are placed in low-temperature storage boxes.

[0003] However, the existing low-temperature preservation boxes are similar to refrigerators, and most of them have an integrated internal structure without a thermal insulation structure in the middle. As a result, when the low-temperature preservation box is opened to take out a tube of antifreeze substance, the remaining reagent tubes will also be exposed, causing large temperature changes. Repeated use will cause the antifreeze substances in the remaining reagent tubes to be damaged, affecting the activity of the Hu sheep sperm; and opening the low-temperature preservation box multiple times will cause the internal cold air to escape, resulting in unnecessary waste.

Cold air flows inside the cold air delivery pipe 1, and the heat preservation tubes 2 are isolated from each other to avoid the exposure of the other semen storage tubes 5 when the semen storage tube 5 is stored, thereby ensuring the quality of the frozen material in the semen storage tube 5 and avoiding damage to the sperm activity. When it is necessary to place the semen storage tube 5 into the heat preservation tube 2, first press the installation tube 3 downward to make the fixed head 15 snap into the slots at different positions, so that the pre-cooling plate 10 and the pre-cooling conduction structure 9 are connected, so as to pre-cool the inside of the installation tube 3 in advance, and ensure that when the semen storage tube 5 is placed, the internal temperature of the installation tube 3 is too high to affect the semen storage tube 5.

When the semen storage tube 5 is placed in the mounting tube 3, the top of the conduction head 94 abuts against the bottom of the pre-cooling plate 10. When the semen storage tube 5 needs to be placed, the mounting tube 3 drives the extrusion wheel 14 to move, and the extrusion wheel 14 squeezes the deformation plate 92, thereby deforming and moving the deformation plate 92, and inserting the top of the conduction head 94 into the thermal insulation component 11, and abutting the bottom of the conduction head 94 and the pre-cooling plate 10 together, thereby pre-cooling the inside of the mounting tube 3 to ensure that the temperature inside the mounting tube 3 is reduced.
