Embryo transfer device and application method thereof

Abstract

The invention aims to provides an embryo transfer device and an application method thereof. By the embryo transfer device and the application method thereof, the embryo can be transferred to a correct position in uterus accurately under ultrasonic guidance so that embryo transfer success rate is increased. The embryo transfer device comprises a hard supporting core, a transfer tube and a guide tube, both the transfer tube and the guide tube are through, and an echo steel coil is arranged at the front end of the guide tube. The application method of the embryo transfer device includes steps of A, placing the supporting core into the guide tube, inserting the guide tube into the uterus, observing the position of the echo steel ring in the guide tube by an ultrasonic unit, regulating the guide tube until the guide tube locates at a proper position of the transferred embryo, and then removing the supporting core; B, connecting an injector with the transfer tube carrying the to-be-transferred embryo, inserting the transfer tube into the guide tube, regulating the position of the transfer tube relative to the guide tube until the transfer tube locates at the proper transfer position; and C, utilizing the injector to carry out implanting of the embryo, and then removing the guide tube and the transfer tube so as to complete the embryo transfer process.

Description

technical field [0001] The invention belongs to the technical field of medical consumables, and in particular relates to an embryo transfer device and a use method thereof which are beneficial to accurately locate the position of a guide tube, thereby improving the success rate of embryo transfer. Background technique [0002] The existing embryo transfer device usually sets the echo steel ring at the end of the transfer tube loaded with embryos, but in the actual embryo transfer process, the guide tube is first inserted instead of the transfer tube, so the echo coil is set at the end of the transfer tube. The steel ring is of little significance. Although there is a metal support core in the guide tube, its diameter is too small, and the echo intensity under ultrasound is weak. It is often difficult to accurately locate the position of the guide tube, which will eventually affect the implantation of the embryo and the outcome of pregnancy. Contents of the invention [000...
