Patent ID: 12010988

Abstract:
This invention provides a low-temperature semen cryopreservation device, comprising: a box body for containing low-temperature cryoprotectant fluid; a tray, one end of which is pivotally connected to the inner side wall of the box body, and a limiting portion is provided on the tray for limiting the movement of the cryoprotectant tube. Two openings are sequentially arranged along the height direction on one side of the box body relative to the hinge end, with the height of one opening higher than that of the hinge end, and the height of the other opening lower than that of the hinge end; a limiting plate, which can be detachably inserted into either opening. When the limiting plate is switched from one opening to the other, the tray tilts to drive the cryopreservation tube to rotate 180 degrees, thereby ensuring the low-temperature cryoprotectant fluid to evenly fumigate the cryopreservation tube, improving the pre-cooling effect.
