Background

The freezing technology of the ovum and the embryo is an important technical link for assisted reproduction, and the survival rate of the frozen ovum/embryo after thawing plays an important role in successful pregnancy. At present, the vitrification freezing technology is more and more widely applied to the preservation of ova and embryos, when the ova or the embryos are subjected to vitrification freezing preservation, after the ova or the embryos are loaded on a slide glass of a carrying rod and liquid nitrogen is rapidly put into the slide glass, the slide glass of the carrying rod needs to be sleeved by a slide glass cap to achieve the effect of protecting gametes or the embryos, then the carrying rod is placed into a freezing storage bracket and transferred into an ova or embryo preservation tank for preservation, and the whole process needs to be operated in the liquid nitrogen. At present, no device special for quickly and safely sleeving a slide into a slide cap in vitrification freezing exists, generally, after vitrification freezing is carried out, a slide rod loaded with an ovum or an embryo is put into a heat preservation box filled with liquid nitrogen, 2 tweezers are used for clamping the slide rod with one hand and the slide cap with the other hand, the slide is sleeved into the slide cap under the liquid level of the liquid nitrogen, then the slide rod is placed into a corresponding freezing storage bracket, and then the slide is transferred into an ovum or embryo storage tank for storage. However, the slide glass of the carrying rod is transparent and thin, the slide glass is difficult to be accurately sleeved into the slide glass cap under the liquid level of liquid nitrogen, and the liquid level of the liquid nitrogen is formed by water vapor condensation, so that the sight is blocked, and the difficulty is great for novices.
