Problems solved by technology

[0004] The technical problem to be solved in the present invention is aimed at the above-mentioned deficiencies of the prior art. According to the larger diameter of the egg, which is about 0.1-0.2 mm, it is easy to block, while the sperm is very small, with a sperm head length of 3.5-5.0 microns and a width of only 2.0-3.0 mm. Micron, it is not easy to "intercept", and the structural characteristics of the fallopian tubes are trumpet-shaped. In terms of design, the present invention has completely changed the traditional concept of blocking sperm in the past various fallopian tube birth control methods, and provides a method of blocking sperm by blocking egg cells. Enter the fallopian tube, simple structure, no interference to normal physiology, simple production and installation, safe and convenient, ideal and reliable birth control effect, more simple and reliable reproductive reproducibility, and reversible fallopian tube umbrella port implantation with practical operation feasibility combined birth control device

Embodiment Construction

[0023] refer to figure 1 , figure 2As shown, the reversible fallopian tube fimbria implanted combined birth control device of the present invention includes a capsule body 1, one side of the capsule body 1 is communicated with the water injection valve 3 through a catheter 2, and the other side of the capsule body 1 is connected to the solid body through a traction fixing line 4. The metal needle 5 is connected, and the capsule body 1 is divided into a three-layer structure, the outer layer is a silicone layer 1a, the middle layer is an ordinary rubber layer 1b, the inner layer is a nylon grid layer 1c, and the outer layer of silicone layer 1a is provided for the capsule body 1. Good biocompatibility, the inner nylon mesh layer 1c increases the strength of the capsule 1, and solves the problem of capsule 1 implantation and removal due to aging and fracture, thin and fragile walls, and tissue growth. It is a difficult problem to achieve the purpose of no need for tubal anasto...

Abstract

The invention discloses a reducible uterine tube umbrella mouth implanted type combined birth control device and belongs to the technical field of uterine tube blockage. The device has a key technicalpoint that the device mainly comprises a sack body, wherein one side of the sack body is communicated with a water injection valve through a pipeline and the other side of the sack body is connectedwith a solid metal needle through a traction fixing thread. The device is simple in structure, convenient in installation and use, ideal in birth control effect and good in reducibility, and is used for reducible birth control of the female.

Description

technical field [0001] The invention relates to a fallopian tube fimbria birth control device, more specifically, it relates to a reversible fallopian tube fimbria implanted combined birth control device by blocking 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 sim...
