Problems solved by technology

The problem that exists when applying above-mentioned carrier device is: the handle of hook, " shovel " or ring is longer, in addition, liquid nitrogen vaporizes in the air, produces mist, when requiring to add outer tube quickly, operation is inconvenient, and the time needed is longer Long, the front end of the freezing hook, "shovel" or ring is easy to be touched, so that the frozen embryo or egg will fall off and be lost; when using the above-mentioned carrier device, if the handle is shortened, due to the The temperature is very low, and the operator is not convenient for hand-held operation and observation

Abstract

The invention discloses a freezing carrier device for vitrifying embryo and ovum in auxiliary procreation technology, which consists of a small cirque, a sliding groove, a supporting structure of the small cirque, a handle, an outer tube, a protective cap and a marking plug. The freezing carrier device for vitrifying the embryo and the ovum in the auxiliary procreation technology can improve the freezing speed of the embryo and the ovum and the defreezing and recovery survival rate of the embryo and the ovum, and reduce the lost of the embryo and the ovum caused by collision and the error and frostbite of operators.

Description

technical field [0001] The invention relates to a cryogenic carrier device, in particular to a carrier device used for loading embryos or oocytes obtained from artificial in vitro culture in human assisted reproductive technology during vitrification cryopreservation. Background technique [0002] At present, in artificial assisted reproductive therapy, under the action of ovulation-stimulating drugs, multiple eggs can be obtained, and multiple embryos can be obtained after in vitro fertilization, but only 1-3 embryos can be implanted during embryo implantation. In order to prevent pregnancy failure or other reasons of demand, the remaining high-quality embryos or eggs are cryopreserved, and the frozen embryos or eggs can be thawed, transplanted or fertilized in the next cycle, which improves the utilization rate of embryos and eggs. Embryos are frozen at minus 196°C, stop developing, and can be stored for several years. [0003] Vitrification, a method of rapidly freezing ...
