Description

Male contraceptive device and method of manufacturing the same

[0001] This application claims priority to Chinese patent application No. 202410084456.4 filed on January 19, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present application relates to the technical field of medical devices, and in particular to a male contraceptive device and a manufacturing method thereof. Background Art

[0003] Male contraceptive devices are medical devices used to reduce the possibility of unwanted pregnancy between sexual partners and are also used to collect semen samples.

[0004] Among the related technologies, one is to achieve the function of receiving the semen ejaculated by male users by means of a tubular film wrapped around the outer circumference of the penis. However, the thickness of the film itself will have a certain impact on the experience of male users during use. The tight fit between the film and the penis to prevent semen from overflowing may cause allergic reactions, rashes or other friction discomfort in male users, affecting the user experience. Another method is usually to form a liquid channel in the vas deferens to guide the semen of male users to flow to the semen storage space formed in the seminal vesicle connected to the vas deferens, thereby achieving the function of retaining semen and achieving the effect of contraception. However, the vas deferens needs to be inserted into the urethra during use, which will cause pain or discomfort to the user, affecting the user's experience. Technical issues

[0047] The present application provides a male contraceptive device 100 .

[0048] In the embodiment of the present application, with reference to Figures 1 to 3, the male contraceptive device 100 includes a sperm storage vesicle 1, a fitting cover 2 and a gel layer 3. The sperm storage vesicle 1 has a sperm storage space, and the sperm storage space has a channel connected to the outside, and the channel includes at least a first liquid channel; the fitting cover 2 is connected to the sperm storage vesicle 1, and the fitting cover 2 has a structure with an opening on one side and a convexity toward the sperm storage vesicle 1 on the other side. A through hole 21 is provided on the side of the fitting cover 2 convex toward the sperm storage vesicle 1, and the first liquid channel is connected to the through hole 21; the gel layer 3 is made of a self-adhesive gel material, and the gel layer 3 is provided on the side of the fitting cover 2 away from the sperm storage vesicle 1. The side of the gel layer 3 away from the sperm storage vesicle 1 is at least partially concave, and the gel layer 3 is provided with a second liquid channel. The surface width between the outer edge of the gel layer 3 away from the second liquid channel and the side of the second liquid channel away from the sperm storage vesicle 1 is not less than 5 mm, and the second liquid channel is connected to the through hole 21.

[0049] In the present embodiment, the sperm storage vesicle 1 is preferably made of soft material, and materials such as silicone, rubber or latex can be used, which are not further limited here. After wearing, the shape of the fitting cover 2 near the side of the sperm storage vesicle 1 should be similar to the shape of the front end of the user's glans penis, and can be trumpet-shaped or bowl-shaped. The specific shape should be selected by the user according to the front end shape of the glans penis of most users, or it can be produced in different shapes, and the user can choose according to his own conditions. The material of the fitting cover 2 is preferably soft and non-toxic, such as silicone, rubber or latex, to improve the comfort of use. A through hole 21 is provided on the fitting cover 2 that is connected to the sperm storage space. When wearing, the user's urethra opening should be aligned with the through hole 21 so that semen can flow into the sperm storage space through the through hole 21 to achieve the collection of semen. Since the male's urethra opening is located at the lower position of the front end of the glans penis, the through hole 21 should also be arranged at the lower position of the fitting cover 2 so that the user's urethra opening can be better aligned with the through hole 21 to avoid the occurrence of semen overflow. Gel layer 3 should be made of a self-adhesive gel material. This gel should be biocompatible, soft, and elastic, ensuring that the male contraceptive device 100 is securely attached to the user's glans penis and is safe and comfortable to use. Examples of such materials include polyurethane gel, hydrogel, and silicone gel, which are not further defined herein. The width between the outer edge of gel layer 3, distal to the second liquid passage, and the second liquid passage should be no less than 5 mm. This appropriate gel adhesion area ensures a secure fit for the male contraceptive device 100, enhances adhesion tightness, and prevents semen leakage.

[0050] The male contraceptive device 100 proposed in the technical solution of the present application includes a sperm storage vesicle 1, a fitting cover 2 and a gel layer 3. The sperm storage vesicle 1 has a sperm storage space for storing semen, and the sperm storage space has a channel connected to the outside world. The channel is at least a first liquid channel. The fitting cover 2 is connected to the sperm storage vesicle 1 and has a through hole 21 connected to the first liquid channel. One side of the fitting cover 2 is open and the other side is convex to the sperm storage vesicle 1, and is used to fit on the user's glans. The gel layer 3 is made of a self-adhesive gel material. The gel layer 3 is arranged on the side of the fitting cover 2 away from the sperm storage vesicle 1. The gel layer 3 has a second liquid channel. The gel layer 3 is away from the second liquid channel. The surface width between the outer edge of the channel and the second liquid channel is not less than 5mm. The first liquid channel, the through hole 21 and the second liquid channel are connected. When wearing the male contraceptive device 100, the fitting cover 2 is placed on the user's glans. The side of the gel layer 3 away from the seminal vesicle 1 has a concave structure. Through the concave structure and self-adhesion, it can fit with the front end of the user's glans. The user's urethra is aligned with the second liquid channel, so that semen can flow into the semen storage space of the seminal vesicle 1 through the second liquid channel, the through hole 21 and the first liquid channel, thereby collecting semen to achieve the contraceptive effect. There is no need to insert the urethra, which improves the user's comfort.

[0051] In one embodiment of the present application, with reference to Figures 2 and 3, the male contraceptive device 100 further includes a fixing ring 4 and a connector 5. There is at least one connector 5, and the connector 5 is used to connect the fixing ring 4 and the fitting cover 2. The fitting cover 2 includes at least two connection points, one connection point connected to one end of a connector 5 or to the fixing ring 4, and the remaining connection points connected to one end of a connector 5, and the other end of the connector 5 is connected to the fixing ring 4.

[0052] In this embodiment, the male contraceptive device 100 is also provided with a fixing ring 4 and a connector 5, which can improve the wearing stability of the male contraceptive device 100 and prevent it from falling off the user's glans penis during use, thereby causing contraceptive failure. The fixing ring 4 needs to be in close contact with the user's coronal sulcus. The fixing ring 4 should be made of a material with a certain degree of elasticity, such as silicone, latex, or rubber. Because the length from the front end of the glans penis to the coronal sulcus varies from user to user, the connector 5 should also be made of a material with a certain degree of elasticity, such as silicone, latex, or rubber. The number of connectors 5 can be selected according to actual needs and can be one, two, or three, etc., and is not further limited here. It is understandable that the number of fixing rings 4 can be one or two, and at least two connection points of the fitting cover 2 are respectively connected to a fixing ring 4, which can increase the stability of wearing. For ease of production and manufacturing, the fixing ring 4 and the connector 5 can be an integrally molded structure to save materials and processing steps.

[0053] In one embodiment of the present application, at least a portion of the opening side of the fitting cover 2 is integrally connected to the sperm storage vesicle 1 , and the remaining portion of the fitting cover 2 is adhesively connected, snap-connected, or plug-connected to the sperm storage vesicle 1 .

[0054] In this embodiment, at least a portion of the open side of the contact cover 2 is integrally formed with the sperm storage vesicle 1, providing ease of processing and a strong and secure fit. The remaining portion is bonded to the sperm storage vesicle 1 by gluing, snapping, or plugging. The specific connection method can be selected based on the actual application scenario and is not further limited here.

[0055] In one embodiment of the present application, the gel material includes polyurethane gel.

[0056] In this embodiment, polyurethane gel is used as gel layer 3. Polyurethane gel is non-toxic and harmless, does not cause skin allergies, can directly contact the user's glans penis, and has a certain degree of self-adhesion, allowing the male contraceptive device 100 to be attached to the user's glans penis. Of course, in other embodiments, gel layer 3 can also be made of a self-adhesive gel material such as hydrogel or silicone gel.

[0057] In one embodiment of the present application, the connecting member 5 and the fixing ring 4 are made of elastic material, and the connecting member 5 and the fixing ring 4 are integrally formed and connected.

[0058] In this embodiment, the connector 5 and the fixing ring 4 are made of an elastic material, such as silicone, latex, or rubber, which can be deformed to accommodate the glans penises of different sizes, allowing all users to use the male contraceptive device 100 for contraception. The connector 5 and the fixing ring 4 are integrally formed, making them easy to process and strong.

[0059] In one embodiment of the present application, the sperm storage vesicle 1 has an initial state and a pressurized state. When the sperm storage vesicle 1 is in the pressurized state, the volume of the sperm storage space is greater than 2 ml.

[0060] The sperm storage sac 1 is also provided with an exhaust channel, the air inlet of the exhaust channel is located on the side of the sperm storage space close to the fitting cover 2, and is located above the opening of the through hole 21 close to the side of the sperm storage space.

[0061] In this embodiment, the sperm storage vesicle 1 has an initial state and a compressed state. If the sperm storage vesicle 1 is made of a rigid material, it will not deform in the compressed state, and the volume of the sperm storage space in the initial state and the compressed state is the same. If the sperm storage vesicle 1 is made of an elastic, deformable material, when the sperm storage vesicle 1 is deformed in the compressed state, the volume of the internal sperm storage space should be greater than 2 ml, so that the minimum capacity of the sperm storage space is greater than the minimum value of 2-6 ml of the typical male single ejaculation volume. The sperm storage vesicle 1 is also provided with an exhaust channel connected to the outside world, so that when semen flows into the sperm storage vesicle 1, it can be exhausted and decompressed through the exhaust channel. This prevents the increase in pressure in the sperm storage space from preventing semen from entering the sperm storage space, resulting in semen leakage and causing contraceptive failure. It is understood that the volume of the sperm storage space in the compressed state of the sperm storage vesicle 1 can be 3 ml, 4 ml, 5 ml, 6 ml, or 7 ml, without further limitation here, and can be selected based on the user's ejaculation volume. The air inlet of the exhaust channel is set in the semen storage space above the semen storage sac 1 and is located above the opening of the through hole 21 close to the semen storage space. Under normal circumstances, as the semen flows into the semen storage space, the liquid level will gradually rise from the lower space of the semen storage space and the front space away from the fitting cover 2 to the upper space of the semen storage space and the rear space close to the fitting cover 2. Since the volume of the semen storage space under pressure is still greater than the ejaculation amount, when ejaculation is completed, the semen liquid level has not yet reached the semen storage space above the opening of the through hole 21 close to the semen storage space. The exhaust channel is set in this space. The exhaust channel will only expel excess gas, and will not cause semen overflow, which will make the contraception ineffective.

[0062] In one embodiment of the present application, referring to FIG. 4 ,

[0063] The fitting cover 2 is made of a flexible material and has a flipping state. When the fitting cover 2 is in the flipping state, the gel layer 3 and the fitting cover 2 are flipped synchronously in the opposite direction of the opening of the fitting cover.

[0064] In this embodiment, the fitting cover 2 is made of a flexible material, such as silicone or rubber. The fitting cover 2 can be flipped with its opening facing the direction of the seminal vesicle 1, and the gel layer 3 can be flipped synchronously with the fitting cover 2. Depending on the length of the fitting cover 2, the length of the flippable part of the fitting cover 2 is also different, so that the gel layer 3 is away from the outer edge of the second liquid channel and close to the seminal vesicle 1, so that the partial surface between the outer edge of the gel layer 3 away from the second liquid channel and the side of the second liquid channel away from the seminal vesicle 1 forms an annular convex structure. Such a structure can make the opening of the second liquid channel away from the seminal vesicle 1 further away from the seminal vesicle 1 than the gel layer 3 is away from the outer edge of the second liquid channel, so that the user can align the second liquid channel with the urethral opening. After aligning the second liquid channel with the urethral opening, the user flips the opening of the fitting cover 2 away from the seminal vesicle 1, and the gel layer 3 flips synchronously, so that the annular convex structure of the gel layer 3 becomes a concave structure, and fits with the front end of the user's glans, which is not only convenient for the user to wear, but also increases the wearing stability.

[0065] In one embodiment of the present application, as shown in FIG1 , the male contraceptive device 100 further includes a check member 6 , which is used to unidirectionally guide the flow from the through hole 21 to the semen storage space.

[0066] In this embodiment, a return member 6 is disposed within the semen storage space, one end of which is connected to the through-hole 21. This member serves to unidirectionally direct the flow from the through-hole 21 to the semen storage space, preventing semen that has entered the semen storage space from overflowing through the through-hole 21 again, thereby improving semen collection efficiency and contraceptive effectiveness. The return member 6 may be a tubular structure made of an elastic material, having a fluid passageway therein. One end is hermetically connected to the through-hole 21 of the contact cover 2, and the other end is provided with a mouth-like slit. The return member 6 has a conductive state, in which it deforms to open the mouth-like slit to allow the fluid to flow through, and a blocked state, in which it closes the mouth-like slit to separate the fluid from the passageway.

[0067] In one embodiment of the present application, the check member 6 includes a base and an opening and closing member, the base has a third liquid channel, the base and the fitting cover 2 are connected so that the third liquid channel is connected to the through hole 21, the opening and closing member and the base can be opened and closed, and the opening and closing member has a conducting state of opening to conduct the through hole 21 to the semen storage space and a blocking state of closing to block the semen storage space from the through hole 21.

[0068] In this embodiment, the check member 6 comprises a base and an opening and closing member. The base defines a third liquid passage. The base is connected to the contact cover 2 to connect the third liquid passage to the through hole 21. The opening and closing member is openably connected to the base, with the opening and closing member having a conductive state (open to connect the through hole 21 to the semen storage space) and a closed state (closed to block the semen storage space from the through hole 21), thereby preventing semen from flowing back. Depending on the method of opening and closing the opening and closing member and the base, the opening and closing member can adopt different structures. In one example, the opening and closing member is a valve flap made of an elastic material. A portion of the valve flap's edge is connected to the end surface of the base near the semen storage space. The valve flap has the ability to deform to open toward the semen storage space to connect the through hole 21 to the semen storage space, and to adhere to the periphery of the third liquid passage of the base to block the flow from the semen storage space to the through hole 21. In another example, the opening and closing member includes a barrier and a baffle. One end of the base is tightly connected to the fitting cover 2, so that the third liquid channel is connected to the through hole 21. The barrier is protruding from the end face of the base close to the semen storage space and encloses a receiving cavity with an opening. The baffle is movably inserted into the receiving cavity and has a conducting state away from the base to conduct the liquid channel, and a blocking state close to the base to separate the liquid channel. In another example, the opening and closing member can be a diaphragm. One end of the base is tightly connected to the fitting cover 2, so that the third liquid channel is connected to the through hole 21. The diaphragm is connected to the end face of the base close to the semen storage space and includes two connection points, which are symmetrically arranged on both sides of the diaphragm. The diaphragm is made of elastic material and has a conducting state in which it deforms to conduct the liquid channel, and a blocking state in which it returns to its original shape to separate the liquid channel. In another example, the opening and closing member includes a baffle and a movable groove. Two connecting posts are symmetrically arranged on either side of the baffle. Two hooks are protruding from at least two connecting posts on the side away from the baffle. Two movable grooves are symmetrically arranged on either side of the base near the semen storage space. The movable grooves are provided with through-holes, and the connecting posts are correspondingly inserted into the through-holes so that the hooks engage and connect within the movable grooves. As long as the check member 6 can ensure the unidirectional flow of the through hole 21 to the semen storage space, the specific structure of the check member 6 is not further limited herein.

[0069] In one embodiment of the present application, as shown in FIG1 , the male contraceptive device 100 further includes a flow guide 7 , which is protruded from the outer peripheral surface of the through hole 21 close to the semen storage space toward the semen storage space, and includes at least one protrusion.

[0070] In this embodiment, the sperm storage vesicle 1 made of a flexible material is easily deformed when subjected to external force. The deformed sperm storage vesicle 1 may block the through hole 21. The setting of the guide member 7 ensures that the deformed sperm storage vesicle 1 is still at a certain distance from the through hole 21, and there is always a certain gap, which ensures that during the semen collection process, the semen can smoothly flow from the inner cavity of the through hole 21 into the sperm storage space in the sperm storage vesicle 1, avoiding affecting the semen collection effect. Among them, the protrusion can be provided with one, two or even more, and this application does not make specific restrictions on this. The provision of the guide member 7 further ensures the smooth flow of semen during the use of the male contraceptive device 100, and further enhances the user experience of the male contraceptive device 100.

[0071] The present application also provides a method for manufacturing a male contraceptive device 100, which is used to manufacture the male contraceptive device 100 as described above. Referring to Figures 5 to 7, the method for manufacturing the male contraceptive device 100 includes the following steps:

[0072] Step S1: connecting the sperm storage vesicle 1 and the fitting cover 2 so that the first liquid channel is in communication with the through hole 21 to obtain an assembly;

[0073] Step S2: The gel layer 3 with the second liquid channel is arranged on the side of the fitting cover 2 away from the seminal vesicle 1 , and the second liquid channel is connected to the through hole 21 .

[0074] In this embodiment, the sperm sac 11 and the fitting cover 22 are first connected, either by gluing or by integral molding, to form an assembly in which the first liquid passage communicates with the through hole 21. Next, a gel layer 33 defining a second liquid passage is attached to the side of the fitting cover 22 facing away from the sperm sac 11, connecting the second liquid passage to the through hole 21. This completes the basic structural assembly of the male contraceptive device 100.

[0075] In one embodiment of the present application, in step S1 , at least a portion of the fitting cover 2 is integrally formed with the sperm storage vesicle 1 , and the remaining portion is connected to the sperm storage vesicle 1 by gluing, snapping, or plugging.

The heating temperature is controlled to be between 50 and 90°C, for example, 50°C, 55°C, 60°C, 65°C, 70°C, 75°C, 80°C, 85°C, 90°C, or any temperature within the aforementioned ranges, without further limitation. The gel reaction time is between 5 and 20 minutes, for a more complete reaction, for example, 5 minutes, 6 minutes, 7 minutes, 8 minutes, 9 minutes, 10 minutes, 11 minutes, 12 minutes, 13 minutes, 14 minutes, 15 minutes, 16 minutes, 17 minutes, 18 minutes, 19 minutes, 20 minutes, or any temperature within the aforementioned ranges, without further limitation.

[0090] In one embodiment of the present application, the ratio of polyether polyol to isocyanate in the gel prepolymer is 100:12-18.

[0091] In this embodiment, the ratio of polyether polyol to isocyanate in the gel prepolymer is 100:12 to 18. The gel prepolymer within this ratio range produces a gel layer 3 with better viscosity, is soft and elastic, is less likely to fall off, has a better contraceptive effect, and is comfortable to use. The ratio can be 100:12, 100:13, 100:14, 100:15, 100:16, 100:17, 100:18, or any ratio within the above ranges, and is not further limited here.
