Test tube baby transplanting device and embryo transplanting method

Abstract

The invention provides a test tube baby transplanting device. The test tube baby transplanting device comprises a deep tube, wherein the upper part of the inner side of the deep tube is connected witha transplanting tube in a sliding manner; the transplanting tube and the deep tube are coaxially arranged; a retractable mechanism for controlling the transplanting tube to do retractable movement isarranged at the lower part of the inner side of the deep tube; the cross section of an inner side cavity of the transplanting tube is oval; a suction opening communicated with the inner side cavity of the transplanting tube is formed in the top end of the transplanting tube; the bottom end of the inner side of the transplanting tube is fixedly connected with a transplanting motor; the tail end ofa main shaft of the transplanting motor is fixedly connected with a transplanting thread rod; the outer side of the transplanting thread rod is in spiral connection with a sleeve; the other end of the sleeve is fixedly connected with a rubber piston block; and the rubber piston block is connected with the inner wall of the transplanting tube in the sliding manner. By adopting the test tube baby transplanting device, the probability that embryos are polluted can be reduced and the success rate of conception is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a test-tube baby transplantation device and an embryo transplantation method. Background technique [0002] Test-tube baby is a common name for in vitro fertilization-embryo transfer technology, which refers to the use of artificial methods to fertilize egg cells and sperm in vitro, and carry out early embryo development, and then transplanted into the mother's uterus to develop and give birth to babies. Initially successfully researched by British obstetrician Patrick Steptoe and physiologist Robert Edwards, this technology has caused a sensation in the world's scientific circles, and the embryos of test-tube babies need to be transplanted into the mother after fertilization. There is an increasing need for a test-tube baby transplantation device and a method of use thereof. [0003] Most of the IVF devices currently on the market have relatively simple settings for tra...

AI Technical Summary

Problems solved by technology

[0003] Most of the IVF devices currently on the market have relatively simple settings for transplantation, and do not consider possible air pollution during the transplantation process. If the embryos are contaminated during the transplantation process, it will reduce the In addition, the existing embryo transfer device does not take care of the main feelings of the transplanted mother, so when the transplantation is performed, it will cause certain stimulation to the uterine muscle tissue of the transplanted mother, and even accidentally injure the muscle tissue , which is not conducive to the overall transplantation work, etc., therefore, a test-tube baby transplantation device and its use method are proposed in view of the above problems
