[0058] specific implementation

[0059] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0060] Case 1

[0061] Such as figure 1 As shown, the highly ductile jelly or paste 10 adopts one or more of polyvinyl acetate, polyvinyl butyral, vinyl acetate-vinyl butyral copolymer Mixtures, polymers mixed with non-toxic or low-toxic organic solvents, non-toxic or low-toxic plasticizers, organic solvents are mainly medical ethanol, which is harmless to human health and the environment, and is a non-toxic and harmless green solvent. You can also add solvents such as isopropanol and methyl acetate with a small proportion (with the development of science and technology, there may be completely non-toxic organic solvents developed in the future to completely replace low-toxic organic solvents. completely non-toxi...

Abstract

The invention discloses an application of an inflation type polymer contraceptive device in urethra, and relates to a contraception application that jelly or paste taking a polymer as a base material is applied to a male urethral orifice and expands to form a film through pressure generated when seminal fluid is ejected. The jelly or the paste has high ductility; the periphery of the jelly or the paste is adhered with a viscous colloid, or the jelly or the paste has viscosity, or the jelly or the paste is connected to the front end of an annular body or the front end of a tubular body in a viscous manner. The invention further discloses a using method and a manufacturing method of the inflation type polymer contraceptive device.

Description

technical field [0001] The invention relates to a contraceptive product, in particular to the application of an inflatable polymer contraceptive device in the urethra. Background technique [0002] Existing condoms, whether they are male or female, have a certain thickness, and the thicker the male, the lower the tactile sensation, causing many males to be unwilling to wear condoms. And if the condom is made thinner, the male's touch will be improved, but the thinner the condom, the easier it will be broken and perforated during sexual intercourse, leading to the risk of contraceptive failure and virus infection. The thinner the condom is, the outer penetration of sperm can be prevented, but the diameter of the virus is much smaller than that of sperm, so it is easy to penetrate out and cause virus infection. Although some condoms made of new materials can be made very thin, they are expensive and not easy to popularize. Moreover, even if they are made thinner, they will st...
