Technical Field

The utility model relates to the technical field of embryo transplantation, in particular to a disposable catheter type transplantation tube.

Background

Embryo transplantation, also called fertilized egg transplantation, refers to a technique of transplanting an early embryo of a female animal or an embryo obtained by in vitro fertilization or other means into the body of the female animal to continue to develop into a new individual. The traditional transplantation methods are of two kinds: one method is to release the embryo stored in the thin tube of embryo into a petri dish, then load it under a microscope into a transplantation needle, and then transplant it into the mother, but this method faces the risk of embryo loss and bacterial contamination; the second method is to cut the embryo tubule and then insert it directly into the mother's oviduct for embryo transplantation, which is difficult to operate and is liable to cause damage and infection to the mother's oviduct. Bacterial contamination is easy to occur in the process of embryo transplantation, or other substances carried from the flesh such as the epidermis and the like enter the oviduct of the mother body in the process of injection, so that the oviduct of the mother body is contaminated and damaged.
