Problems solved by technology

At present, the widely used IUDs have many types of structures and have good birth control effects, but after investigation, it is found that there are still many deficiencies in their application: the IUDs are easy to fall off, easy to shift, easy to cause bleeding to cause infection, and the IUDs are easy to fall off. Pregnancy, backache, abdominal drop, etc.
Although those skilled in the art have made various improvements to birth control measures, due to problems such as low operability and poor safety, no birth control device can overcome the many shortcomings of the prior art so far.

Abstract

The invention discloses a cervical contraceptive device which contains a traditional Chinese medicine which is prepared from a medicinal herb of radix polygalae and used for killing sperms. The cervical contraceptive device comprises a circular tube bracket. The wall of the circular tube bracket comprises two layers, i.e., an outer layer which is a meshy wall braided with Nitinol wires and an inner layer which is a methyl vinyl silicone rubber layer with a thickness of 0.5mm to 1mm; one end of the circular tube bracket is provided with a first fixed circular ring, the other end of the circular tube bracket is provided with a second fixed circular ring; a slow-release suppository prepared from the medicinal herb of radix polygalae is installed in the circular tube bracket; the slow-release suppository prepared from medicinal herb of radix polygalae takes the shape of the head of a bullet, and a clearance is set between the outer perine of the slow-release suppository and the inner wall of the methyl vinyl silicone rubber layer; and a suppository fixing mesh is installed in a position in which the outer end of the second fixed circular ring is connected with the outer wall of the circular tube bracket. The cervical contraceptive device has reasonable structure and design. According to 3-year statistics of 265 cases of women of child-bearing age who use the device, symptoms of falling off, replacement, bleeding, infection, sore in waist, abdominal pain or intramural embedment and the like of the device never happen. The cervical contraceptive device provides a safe and reliable contraceptive device without side effects or complicating diseases for women of child-bearing age.
