specific Embodiment 1

[0019] Specific embodiment one: see figure 1 . figure 1 As shown, the condom 10 is impregnated with natural latex, and includes an isometric condom body 3 with an open end 1 and a closed end 2, the closed end has a sperm storage bag 4, and the open end has a crimp 5 . The diameter of the condom body 3 is 32mm±1mm, and the nominal width is 52±2mm. The length of the condom body 3 is 1.5 to 3 times the length of a common condom, and is between 280mm and 480mm.

[0020] When the condom is used, the inner diameter of the sealing ring formed at the base of the penis is slightly smaller than the diameter of the condom body. Because the diameter of the sealing ring is significantly larger than that of the penis, and it also has good expansibility, under the joint action of the extrusion of the root of the penis and the contraction of the vaginal opening, the condom will not fall off into the vagina, and it also has the effect of preventing semen from leaking Effect. When the cond...

specific Embodiment 2

[0021] Specific embodiment two: see figure 2 . figure 2 As shown, the condom 10 includes a different-diameter condom body 3 with an open end 1 and a closed end 2, the closed end has a sperm storage bag 4, the open end has a crimp 5, and the condom body 3 Divide into two parts cylinder body 6 and cylinder body 7. The diameter of the condom body 6 is 32mm±1mm, the nominal width is 52±2mm, and the length is 160mm+20mm. The diameter of the condom body 7 is 34 mm ± 1 mm, and the length is 1 to 2 times the length of the condom body, which is between 160 mm and 320 mm.

[0022] When using this kind of condom, the outer diameter of the seal ring formed at the root of the penis is significantly larger than that of the penis, and the effect of preventing the condom from falling into the vagina and semen from leaking out is obvious. In this kind of condom, the inner diameter of the sealing ring is not smaller than the diameter of the cylinder that is inserted into the penis, and is ...

specific Embodiment 3

[0023] Specific embodiment three, see image 3 . image 3 As shown, the condom 10 includes a different-diameter condom body 3 with an open end 1 and a closed end 2, the closed end has a sperm storage bag 4, the open end has a crimp 5, and the condom body 3 Divide into two parts cylinder body 6 and cylinder body 7. The diameter of the condom body 6 is 32mm±1mm, the nominal width is 52±2mm, and the length is 160mm+20mm. The diameter of the condom body 7 is 30 mm ± 1 mm, and the length is 1 to 2 times the length of the condom body, which is between 160 mm and 320 mm.

[0024] When this kind of condom is used, the inner diameter of the sealing ring formed at the base of the penis is obviously smaller than the diameter of the cylindrical body inserted into the penis. The condom not only has the functions of preventing shedding and semen leakage, but also has the effect of slowing down the blood flow rate of the penis and prolonging the time of sexual intercourse.

Abstract

A novel condom able to prevent it from dropping in vagina and the sperm from coming in vagina is made of elastic materials. It is a tubular body with a closed end having a sperm storing bag and an open end with rolled edge. It features that its length is 1.5-3 times longer than that of ordinary condom.

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 prevent disease infection and prevent AIDS. People have to choose the condom that the diameter of the condom barrel body is less than the diameter of the penis in order to prevent the condom from coming off in the vagina, or choose a condom with a binding mouth. However, due to inappropriate selection of condoms or incorrect use methods, or excessive activity, the condom may fall off into the vagina. Or when the amount of male ejaculation is large, after the semen in the semen storage bag is full, part of the semen will overflow out of the condom port, and then flow into the vagina. The above-mentioned phenomenon of condom falling off or semen overflowing will not only lead to unintended pregnancy of the woman, but also increase the chance of cross-infection of diseases. Even if you choose the right co...
