Anti-body fluid cross condom and its production tool

Abstract

An anti-body fluid cross-over condom, comprising a sheath (1) with a closed front end, where the closed front end of the sheath (1) is a glans accommodating space, an inner sleeve (2) is arranged inside the outer sheath (1), and the front end of the inner sheath (2) and the rear end are open, the diameter of the front end of the inner sleeve (2) is smaller than the diameter of the rear end, the inner sleeve (2) is located at the back of the glans, the diameter of the front end of the inner sleeve (2) is at least smaller than the diameter of the outer sleeve (1), and the inner sleeve (2) At least the front end of the tube (2) is tightened on the penis at the back of the glans, and the rear end of the inner sleeve (2) is connected with the outer sleeve (1), and a body fluid with an open front is formed between the inner sleeve (2) and the outer sleeve (1) Hold space (3). Also provided is a condom production tool. The condom can effectively prevent backflow of body fluids, and improve the effect of contraception and prevention of disease transmission.

Description

technical field [0001] The invention relates to a condom, in particular to a body fluid cross preventing condom and a production tool thereof, which are applied in the fields of family planning, prevention of disease transmission through sexual routes, and the like. Background technique [0002] Condoms are effective contraceptive tools during people's sexual life, and can prevent disease transmission caused by body fluid crossing during sexual life. The existing condom is cylindrical, and the front end is provided with a seminal vesicle, which is used to accommodate semen and prevent semen from leaking out. [0003] technical problem [0004] In actual sexual life, ejaculation is rhythmic and completed several times in short intervals. In order to get better pleasure, the ejaculator will involuntarily thrust several times during and after ejaculation, so that the semen in the seminal vesicle at the front end will be released. Under the extrusion of the pumping action, the...

Problems solved by technology

The inner circular through hole of the barrier ring of this patented technology is located at the top of the penis, and the seal is realized by pressing the glans towards the closed end of the sleeve body. However, in actual use, the two can only be close together during the insertion action, and the sleeve body does not move backward during the reverse action. Therefore, the same compression state cannot be maintained. Even if the sleeve body is pulled backward to make it compact when worn, the sleeve body is only attached to the penis cortex, and the penis cortex can be longitudinally within a certain range relative to the internal cavernous body of the penis. Move, the compressed state is still difficult to last under the action of elastic force, so the disadvantage of semen backflow still remains, and this problem still needs to be solved technically
