Abstract

The invention relates to an embryo transplantation tube which comprises an outer tube, a heat insulation tube and an embryo tube. The heat insulation tube is of an open or closed structural form. The heat insulation tube comprises a heating layer and a heat insulation layer. The outer tube is connected in the heat insulation tube. The outer tube comprises a straight part and a bent part. The bent part and the straight part are integrally formed in one time, one end of the straight part is provided with a fixed bolt, the other end of the straight part is provided with a cervix opening fixing part, and the cervix opening fixing part is movably connected to the straight part of the outer tube, the bent part is marked with a graduated scale, and the peripheral surface of the bent part is sleeved with a sealing cap. The embryo transplantation tube has the advantages that the embryo transplantation tube is low in cost, clinicians and laboratory workers operate the embryo transplantation tube conveniently, the transplanting efficiency is improved, the surgical operation time is shortened, the embryo transplantation tube has a fixing effect and conforms to the human physiological anatomy structure, it is guaranteed that an embryo is in a homoiothermal state before implantation, the embryo implantation rate and pregnancy rate can be improved, and the embryo transplantation tube can be further clinically popularized and applied later.

Description

technical field [0001] The invention relates to the technical field of fetal transplantation, in particular to an embryo transfer tube. Background technique [0002] In vitro fertilization-embryo transfer technology (commonly known as test-tube baby) is an effective means to treat refractory infertility. In general, it is divided into the following steps: ovulation induction, egg retrieval, in vitro fertilization, embryo transfer and luteal support. Among them, in vitro fertilization-embryo transfer is a process in which gametes form embryos outside the body, and then the embryos are transplanted back into the female body, which plays a connecting role in IVF. Embryo transfer is one of the key links, but the existing embryo transfer operation has the following deficiencies and defects. [0003] First of all, the embryo transfer tube used in the prior art is usually imported from abroad, and the cost is high. The embryo transfer tube in the existing technology is a sleeve-t...
