Description

Improved embryo transplantation tube

Technical Field

The utility model relates to the technical field of embryo transplantation tubes, in particular to an improved embryo transplantation tube.

Background

The embryo transfer tube is a disposable medical consumable for transferring the embryo cultured in vitro into the uterine cavity by a specially designed special tube. The using method comprises the steps of placing the inner core of the outer sleeve into the outer sleeve after the vagina is opened by the vaginal speculum, inserting the outer sleeve containing the inner core into the cervical canal in advance, wherein the insertion depth is generally 4-5 cm, and the insertion depth needs to be adjusted according to the length of the cervical canal of each person. Then the inner core is pulled out, and the inner sleeve filled with the embryo is inserted into the outer sleeve to send the embryo into the uterine cavity. The insertion depth of the outer sleeve is proper, and after the proper depth is found, the fixing ring is just blocked at the cervix by adjusting the fixing ring on the outer sleeve, so that the outer sleeve is prevented from being displaced in the waiting process.

Need estimate the male degree of depth once in advance when embryo transfer pipe uses under prior art to adjust the position of retainer plate, if the degree of depth is improper after inserting, when needing readjustment retainer plate, either pull out readjustment, perhaps stretch into the vagina deep with the oval pincers and carry the retainer plate, inject a bit or pull out a bit with the outer tube again and adjust, be difficult for also can't see shortcoming such as scale mark of front end clearly with the range of accuse removal retainer plate. In addition, the number of times of the outer sleeve going in and out is increased in the adjusting process, the intima is easily injured to cause bleeding, and the success rate of the test-tube baby is easily influenced by the bleeding. The improved embryo transplantation tube is not pulled out, the ovum circular forceps are used for stretching in to adjust, the inconvenience in use can also cause sight line obstruction, the sight line obstruction can not be clearly adjusted, the fixation between the fixing ring and the outer sleeve is unreliable, the fixing ring and the outer sleeve can slide, the stability is general, and therefore the improved embryo transplantation tube is provided.

SUMMERY OF THE UTILITY MODEL
