Condom

Abstract

The invention discloses a condom comprising a cylinder with open end or closed end, and an inflatable packer filled gas with a round hole in the middle whose aperture is tiny smaller than diameter of penis while the exterior margin of inflatable packer is tiny bigger than exterior margin of vagina. The connection between open end of condom and inflatable packer can be processed by producing each earlier than connecting or by alternative method that making a small part of condom cylinder as a part of inflatable packer earlier than connecting. The open end is through the middle hole. Said condom can efficiently prevent the condom slipping, overflow of semen; reduce the fettered feeling of penis; and promote contraceptive success rate. The condom improved on this invention can increase excitability and prevent cross-infection of venereal disease efficiently.

Description

Technical field: [0001] The present invention relates to a condom. Background technique: [0002] The male condom is easy to use, not only can prevent pregnancy, but also can reduce and prevent some diseases. During use, male condoms often fall off due to inappropriate selection of condom size or vigorous activity, and semen flows into the uterus, which will lead to unintended pregnancy of the woman and increase the chance of cross-infection of diseases. People have to choose the condom whose diameter of the condom body is smaller than the diameter of the penis, because the restraint of the body of the condom affects the blood flow of the penis, making people feel uncomfortable; After male ejaculation, because the penis is soft, there is still the risk of the condom falling off, so he has to hold the open end of the condom with his hand within a short time after ejaculation, and pull it out of the vagina together with the penis, which makes the sexual life feel tense. Even...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned anti-slip condom is only limited to solving the technical problem that the condom is easy to fall off. Because the elastic anti-slip ring body is tightened on the penis, the penis has a greater feeling of being restrained during use. The fastening force between the elastic anti-slip body and the penis becomes smaller, there is still the risk of the condom slipping off, and there is still the problem of semen easily overflowing the condom port and flowing into the vagina, resulting in contraceptive failure

In addition, the above-mentioned anti-slip condom has an anti-slip ring body with a diameter smaller than that of the penis, which is difficult to put on the penis and is inconvenient to use.

[0005] The above-mentioned anti-slip condom itself only isolates the penis and vagina of men and women, and cannot effectively prevent cross-infection of the vulva part of men and women, and cannot fully meet people's requirements for preventing sexually transmitted diseases

And most of the prior art is by adding a sheet-shaped isolation film, and then wearing and fixing it through a traction device. The manufacturing process is relatively complicated, and it is inconvenient to wear and fix it.
