Reducible uterine tube birth control sleeve

Abstract

The invention discloses a reducible uterine tube birth control sleeve and belongs to the technical field of female birth control devices. The reducible uterine tube birth control sleeve has a key technical point that the reducible uterine tube birth control sleeve comprises an elastic sleeve body, wherein the sleeve body sequentially consists of a sleeve mouth, a neck part, a body part and a tailpart; the sleeve mouth is in a tubaeform and part of the edge of the sleeve mouth is thickened; the neck part is in a bottle neck shape and the size of the neck part corresponds to the diameter of theampulla of a human uterine tube; the tail part is also in a tubaeform and an open shape; and the sleeve body is also provided with a liquid penetration hole with a hole diameter smaller than the diameter of a ovum. The reducible uterine tube birth control sleeve is simple in structure, convenient in installation and use, few in side effects, ideal in birth control effect and good in reducibilityand is used for reducible birth control of the female.

Description

technical field [0001] The invention relates to a female fallopian tube contraceptive device, more specifically, it relates to a reversible fallopian tube contraceptive sleeve which prevents egg cells from entering the fallopian tube. Background technique [0002] At present, non-hormonal drugs for female contraception include barrier contraception, intrauterine devices, tubal sterilization, etc., which are all used clinically, each with its own advantages and disadvantages. Tubal sterilization is a widely used contraceptive method for women in clinical practice, mainly including tubal ligation, tubal ring, clip sterilization, tubal sticking, tubal embolism, etc. All kinds of tubal sterilization in the past mainly use various mechanical blocking effects to prevent sperm from entering the fallopian tube to achieve the purpose of birth control, but it does not affect the entry of egg cells into the fallopian tube. Although tubal sterilization is a simple, safe, and efficient ...

AI Technical Summary

Problems solved by technology

[0004] Umbrella embedding of the fallopian tube and ovary embedding, the principle is: after the egg is produced by the ovary, there is a space distance for the egg to enter the fallopian tube. The egg does not have the ability to move freely like the sperm. The egg itself does not have the function of "walking". The spatial distance of the fallopian tubes is achieved through the fallopian tube fimbria "catching" eggs (picking up eggs) and then through the peristalsis of the fallopian tubes to achieve position changes. Using this spatial distance, the peritoneum separates the ovaries and fallopian tubes into two different spaces: the abdominal cavity With the retroperitoneum, the umbrella of the fallopian tube cannot "catch" eggs and prevent egg cells from entering the fallopian tubes. However, this operation is extremely complicated, traumatic, and has a high failure rate.
