Description

 Title of Invention: Anti-body fluid cross condom and its production tools

 [0001] The present invention relates to a condom, and more particularly to an anti-body fluid cross condom and a production tool thereof, which are applied to the fields of family planning, preventive route infection and the like.

 Background technique

 [0002] Condoms are effective contraceptive tools for people's sexual life, and they can prevent the spread of diseases caused by the crossover of sexual life. The existing condom is cylindrical and has a seminal vesicle at the front end for containing semen to prevent semen leakage.

 technical problem

 [0003] In actual sexual life, ejaculation is rhythmic, repeated several times intermittently, in order to better get pleasure, ejaculation and ejaculation after ejaculation will involuntarily thrust a few times, this will make the front end of the seminal vesicle The semen overflows along the inner wall of the condom under the squeeze action, causing the fluid to cross, which increases the probability of contraceptive failure and disease transmission. There is also a fluid-liquid crossover that does not only exist in the ejaculation stage. During the whole sexual life, the condom wearer continuously secretes and lubricates the body fluid, and during the pumping action, the body fluid is also squeezed out of the end of the condom, causing the body fluid to cross. It also causes body fluids to cross. In order to prevent the problem of reflux of body fluids, the prior art has not yet been better solved.

 [0004] For example, the document of the publication No. CN2778239Y, Patent No. 200520069737.5 discloses a leak-proof condom which is connected between the seminal vesicle 1 and the glans by a flow passage port composed of the upper layer valve 2 and the lower layer valve 3, by the glans The liquid flowing out from the anterior urethral orifice enters the seminal vesicle through the flow port between the two valves. The seminal vesicle stores the liquid entering it. Since there is no negative pressure in the seminal vesicle to draw in the liquid, the liquid itself does not allow the liquid to flow in completely. The seminal vesicle, the pumping action, the pressure is dispersed, and does not concentrate the liquid into the seminal vesicle. Some liquid will flow out along the inner wall of the condom with the pumping action, causing the body fluid to cross, the risk of contraceptive failure and infectious diseases remains. Very high.

[0005] For example, an anti-overflow condom is disclosed in the document of the publication No. CN2479943Y, application No. 01222339.5, and an anti-overflow membrane 3 is provided between the pouch 2 and the glans, and the glans mouth communicates with the pouch 2 through the liquid outlet 4, Under the action of the dispersion pressure generated by the thrusting, the liquid flowing out of the urethral orifice of the glans can not be concentrated into the pouch. There is still some liquid that will flow out of the end of the condom with the pumping action, and there is the same risk.

 [0006] As another example, the document of the publication No. CN203154041U, application No. 201320080331.1 discloses a barrier ring type condom which is provided with a barrier ring 3 at the closed end of the sleeve body, and the pressure of the top of the penis is fully contacted with the barrier ring. The inlet of the barrier ring is tightly closed, and the ejaculation of the penis head is aligned with the obstruction area through the inner circular through hole of the barrier ring (see paragraph 15). The barrier ring is naturally extended to the closed end of the sheath by the pressure at the top of the penis, blocking The elastic force of the ring and the pressure at the top of the penis work together to keep the two close together, ensuring the closure of the barrier space (see paragraph 29) to solve the problem of semen backflow. The patented technical barrier ring has an inner circular through hole at the top of the penis, and is pressed against the closed end of the sleeve by the glans to achieve sealing. However, the actual use of the cymbal is only the insertion action, and the two can be pressed tightly, and the reverse action 吋 sleeve is not backward. The tension is not able to maintain the same compression state. Even if the shackle is pulled backwards to pull the sleeve to compress it, the sleeve is only attached to the outer skin of the penis, and the outer skin of the penis can be longitudinally within a certain range relative to the internal corpus cavernosum. Movement, the compression state is still difficult to last under the action of elastic force, so the drawbacks of semen reflux are still there, and this problem still needs to be solved by technology.

 BEST MODE FOR CARRYING OUT THE INVENTION

BEST MODE FOR CARRYING OUT THE INVENTION [0095] For a preferred embodiment of the invention, see Example 7 of the embodiments of the invention described below.

Embodiments of the invention

 [0096] In order to better understand the present invention, the technical solutions of the present invention will be described by way of embodiments with reference to the accompanying drawings, and the same components and configurations in the respective embodiments are described in the foregoing embodiments, and in the following embodiments, By default, this description is not a lack of technical features, and is hereby stated.

 [0097] Embodiment 1, as shown in FIG. 1 , the body fluid cross-over condom is provided with a jacket 1 with a front end closed, and the front end of the jacket 1 is a glans accommodating space, and the glans head is placed in the glans accommodating space; The inner sleeve 1 is provided with an elastic inner sleeve 2, the inner sleeve 2 is substantially the same direction as the outer sleeve 1, and the inner sleeve 2 has a circular cross section, and the front end and the rear end of the inner sleeve 2 are respectively laid, and the inner sleeve 2 is front end The diameter of the sleeve 2 is smaller than the diameter of the rear end. In this embodiment, the sleeve 2 is gradually enlarged from the front end to the rear, and has a tapered shape as a whole; the inner sleeve 2 is located at the rear of the glans, and the inner sleeve 2 has at least a front end diameter smaller than the diameter of the outer sleeve 1. The front end of the inner sleeve 2 is tightly clamped on the penis of the back of the glans by its own elastic force. There is no gap between the front end of the inner sleeve 2 and the penis, and the rear section gradually relaxes the degree of tightness to the penis; The end is connected to the inner wall of the outer casing 1, and the inner casing 2 and the outer casing 1 form a front-loaded body fluid accommodating space 3, and the body fluid accommodating space 3 means a space for accommodating the body fluid flowing to the rear along the inner wall of the outer casing 1. The inner sleeve 2 can be integrally formed with the outer sleeve, or can be separately formed and then bonded.

 [0098] The sleeve structure package 吋 is rolled up from the end of the outer end of the outer sleeve 1 to the glans accommodating space, and the inner sleeve 2 has elasticity, and the curling action starts from the rear part, part or all of the roll Put it in and put it in the bag. When the inner sleeve 2 is partially wound into the crucible, the front end of the inner sleeve 2 is not rolled up. After the glans are used, the glans contain the air and then wrap the glans. After the glans are spread over the glans, the tuck is slightly pulled. Body, because the outer sleeve and the glans are elastic, it is easy to use even if the front end of the inner sleeve 2 falls into the coronal groove, and the loose sleeve continues to be swollen to the root of the penis; the crimping method is more suitable for the front end of the inner sleeve 2 The front sleeve.

[0099] When the front end of the inner sleeve 2 is relatively rearward, it can be fully entangled, and the pullable strip 41 can be rolled up together with the outer side of the outer sleeve. The front end of the pull belt 41 forms a pulling end 42 and the pulling end 42 can be fully wound. Into the outer casing, as shown in Fig. 25, the casing in the figure is in a state in which the drawstring has not been rolled up, and the pull-up end 42 will be wound into the sleeve after being rolled up; the pull-up end 42 may not be fully wound into the outer casing, as shown in Fig. 26. In the figure, the sleeve is in the rolled up state, and the pulling end 42 is not wound into the sleeve; the pulling end 42 is not involved in the sleeve, and the holding end 42 must be located before the inner sleeve 2, The rear end of the strap is located behind the front end of the inner sleeve 2; the strap may be one or more than two, one for each 吋 can be strip-shaped or cylindrical, the drawstring is more than two 吋, the rear end can be connected together, and the pull-up end 42 can also be multiple; using 吋, the glans contain space to exclude air and wrap The glans, the curled portion is stretched to expose the pulling end 42, and then the pulling end 42 is pulled back, and the curled sleeve is stretched by the pulling belt, so that the front end of the inner sleeve 2 is turned into the inner side of the outer sleeve, and is tightly hung on the penis. After the strap is fully extended, remove the strap and continue to extend the sleeve to the base of the penis for use.

[0100] When the front end of the inner sleeve 2 is relatively rearward, it can be completely entangled, and the rib 44 can be connected between the front end of the inner sleeve 2 and the outer sleeve 1. As shown in FIG. 31, the glans accommodating space is excluded by using 吋. After the air wraps the glans, the curled sleeve is stretched, and the front end of the inner sleeve 2 is turned over and pulled onto the penis by the lacing 44, and the sleeve is swollen to the root of the penis, and the body fluid is used by the window between the ribs 45 It flows backward to the body fluid accommodating space 3, which is simpler than the draw tape type.

 [0101] When the front end of the inner sleeve 2 is relatively rearward, an axial stack may be disposed on the outer casing of the front portion of the joint of the outer sleeve 1 and the inner sleeve 2, as shown in FIGS. 32 and 33, and stacked in FIG. The folding stack 46 is shown in Fig. 33, and the stack is a wave stack 47, as long as it can shorten the axial extension of the outer sleeve, such as natural pleat stacking, spiral type, and inner sleeve. The front end of the tube 2 is close to the glans accommodating space at the front end of the outer casing 1. When the shape is matched, the two can be attached together, and the stack is rolled up with the outer sleeve 1 and the inner sleeve 2, and can be put into the package after being rolled. After using the 吋, the glans contain space to exclude the air and wrap the glans. After the slab is over the stacking position, the shovel is stopped, and the rolled up part of the casing is unfolded, and the stack of the outer casing 1 is axially stretched. The inner casing 2 is partially pulled and pulled back. Since the front end of the inner casing 2 and the glans are elastic, it is easy to cause the front end of the inner casing 2 to fall into the coronal groove at the back of the glans, and then continue to expand the casing. Roll up the part to the root of the penis and use it; this method is simpler than the drawing method. In order to determine the stacking position well, it may be further marked with a pattern of other colors on the jacket at the stack or on the inner sleeve at the corresponding stack.

[0102] Using the 吋, the front end of the inner sleeve 2 is tightly clamped on the penis at the back of the glans, and the body fluid and semen secreted by the wearer flow along the inner side to the rear end of the outer casing 1 during the pumping process, and the liquid flows to the inner sleeve 2 The front end 吋, because the front end of the inner sleeve 2 is tightly clamped on the penis, the tight portion has no gap to the liquid in a high resistance state, and the rear portion is in a low resistance state, under the guidance of the low resistance passage between the inner sleeve and the outer sleeve The liquid flows to the rear closed space and is stored in the body fluid accommodating space 3, and is not leaked from the tail end of the outer casing, thereby preventing the wearer from contacting the body fluid and the semen, and effectively improving the effect of contraception and disease prevention. [0103] In the same way, the structure effectively improves the accommodation space of the semen and the body fluid, and is not limited to the front end of the outer casing 1. The volume space is distributed around the front half of the outer casing, and has strong dispersibility, effectively preventing the liquid from accumulating in front. The part is crushed and broken.

 [0104] Further, the penis is covered by the inner sleeve 2 and the outer casing 1 of the inner sleeve 2, and does not come into contact with the wearer's body fluid, and the sputum is not easily lubricated by the body fluid, and is clean and comfortable after being taken off. .

 [0105] Since the front end of the inner sleeve 2 is elastically bound to the penis, the binding force of the inner sleeve 2 forms a large frictional resistance between the front end of the inner sleeve 2 and the penis, and is affected by the frictional resistance, pulling the end of the outer sleeve 1 off. , the inner sleeve 2 is turned outward, and the inner sleeve 2 is finally separated from the cockroach penis under the frictional resistance retention, and the inner sleeve 2 is turned over without the body fluid of both sides, so that the other body fluid on the outer surface of the outer sleeve 1 is not easily stained. To the wearer's glans, the body fluid can be further prevented from crossing; while the existing condoms not only wear the body fluid at the end of the wearer, but also cross the body fluid contaminated at the end of the condom. At the glans site, the technique can be effectively reduced or avoided on these issues.

 [0106] By the elastic binding force of the front end of the inner sleeve 2, when the wearer pulls out the sputum from the other body, the initial stage is not held by the hand, and the whole body does not fall off in the other body, but the process of the inner sleeve 2 gradually eversion The front end of the inner sleeve 2 is moved to the crown groove, and the front end is embedded in the crown groove. Under the edge of the protruding head of the glans, the retention effect on the front end of the inner sleeve 2 is obviously increased, and the inner sleeve 2 is finally separated.

 [0107] Sexual life 吋, feeling and impulsiveness mainly come from the glans, the inner casing 2 does not cover the glans, so it does not affect the stimulation caused by the friction to the glans, and maintains the pleasure of the glans stimulation, but the inner casing 2 wrapped in the secondary sense of the impulse and the source of the impulsive part of the head of the glans, the coat 1 and its two-layer structure, can be isolated to reduce frictional stimulation, can inhibit the pleasure of the penis, achieve some delay, give the other side more climax.

[0108] Regarding the inner sleeve shape, in the example, the inner sleeve 2 is gradually enlarged from the front end to the rear end, and has a tapered shape as a whole, and in addition to this linear change, other shapes which are nonlinearly changed may be employed. , such as curve changes, step changes, and is not limited to always increase and the diameter of the inner casing leading edge is the smallest, as shown in Figure 2, the front section of the inner casing is convex, and the front section of the inner casing is concave, as shown in Figure 3. 4 shows the front section of the inner sleeve is stepped, the front section of the inner sleeve is wavy as shown in Fig. 5, and the front side of the inner sleeve is not the smallest diameter as shown in Fig. 6. It only needs to satisfy the diameter of the front end of the inner sleeve which is smaller than the diameter of the rear end. The front end of the sleeve is sized to fit the penis at the back of the glans, and the rear end of the inner sleeve is sized to be connected to the outer sleeve, and is not limited to these forms; the inner sleeve is axially longer The crucible can be axially divided into two parts, the rear section is the cylinder 201, and the front section is the reduction cylinder 202, as shown in Figs. 2 to 5, which can maintain the front end sealing property and reduce the pressure of the rear section on the penis. It also has a large body fluid accommodating space 3; the reciprocal change of the diameter can also make the variable diameter cylinder 202 better positioned on the penis, the hoop is firmer and the sealing is better.
