Abstract

The main concept of this female condom design is to protect females from infectious diseases and prevent sperm from entering the vagina through a unique double-membrane column and extended protective membrane design that completely obscures female reproductive organs during sexual intercourse. The female condom is composed of a double-layered film column and a stretch film. The omega columnar body is designed as a condom to form a vaginal protective film, and the extended cover portion is adhered to the female genital vulva to completely prevent liquid contact. At the same time, the Omega column can also be reversed as a male condom. The double column is designed for unconventional sexual behavior. The lateral and longitudinal folds are designed to increase the plasticity of the columnar portion. This female condom can be made according to the user's preferred shape, texture, color and taste.

Description

Female condoms, procedures for making female condoms and the ability to make omega-like or Similar shaped condom design sealing device

The present invention generally relates to female condoms. In particular, the primary design of the present invention is intended to utilize the action of a layer film as a means of isolating infectious diseases and the passage of spermatozoa through the vagina during sexual intercourse. A thin, flexible, extended-cover design female condom can isolate direct contact between the genitals and fluids of sexual partners. At the same time, this design is intended to create a female condom that is easier to use and less expensive than the current one.

It is extremely urgent to create an excellent protection against infectious infections. The world's population has increased year by year, and the expected rate of pregnancy has also increased year by year. Sexually transmitted diseases, such as: AIDS is distributed worldwide. There are a number of preventive devices that have been introduced to reduce these factors, some of which are indeed effective, but so far no device has been able to comprehensively combine contraception and prevention of sexually transmitted diseases.

It is well known that existing condoms are inadequate. It must be maintained by the firmness of the penis. And it only wraps the penis part instead of the genital part, so it still can't control such as: herpes, sputum through the genital, anal or oral sex infection. In addition, the use or not is based on the will of the man and there are many inconveniences in the operation, such as in the dim light, often cause operational errors, and its too tight effect makes the penis feel worse.

The female condom just gives everyone the option of another condom. US Patent No. 5,094,450 (Fig. 1a) HESSEL describes an open film column device that is proximal to the cervix at the columnar end It contains internal hemorrhoids, and the outer ring is at the end of the beginning. However, this device only covers part of the genitals rather than all. Based on this, it does not prevent diseases that are infected through contact with the genital area or body fluid exchange. Plus its manufacturing costs far exceed the usual condoms.

In order to avoid the exchange of body fluids during sexual intercourse and to cover all the genitals to achieve contraception and disease prevention, US Patent No. 5269320 (Fig. 1b) HUNNICUTT has introduced a colloidal female condom with adhesive and extended cover functions. The portion of the extended cover is fixed to the genital and perineal parts in a sticky manner. The part that extends the screening function can be used as a panty or a male panty.

U.S. Patent No. 4,889,184 (Fig. 1c) SKURKOVICH's latex female condom extends a wider range of coverage and is secured to the genital area with a micro-adhesive or sling.

US Patent No. 5515862 (Fig. 1d) ARTSI introduces another similar female condom with a wider range of coverage. The beginning of the shield is composed of six areas of continuous seamless joints. The range of adhesion covers the pubic hairline. The columnar part is folded in a hexagonal shape, like the pattern of Hunnicutt.

The three adhesive female condoms mentioned above are made of waterproof, impervious film, such as latex or other bio-functional glue such as polyurethane, polyethylene, polypropylene, polyester fiber, nylon, poly Vinyl chloride, biopolymer, nitrile rubber, etc. Based on the structure of the shield and the columnar body forming a vertical shape or being connected to the columnar body at an angle, the manufacturing process of these female condoms is complicated and complicated, and the adhesive medium is attached to the shield part alone, and the column is attached. It has been difficult to make the shape of the body in the middle of the shelter. The use of latex as described in Figures 1b, 1c, complicated casting and adhesion procedures, results in a relatively high cost. On the other hand, if a flexible film is used, it is impossible to manufacture a shield portion of "continuous seamless joint" as described by Artsi, because the material of the film makes it difficult to manufacture. For example, it is technically difficult to fold a columnar film in a hexagonal shape as described by Artsi.

Therefore, a low-cost, female condom that is easy to manufacture/operate and has extended protection is urgent. In order to protect the internal and external parts of the reproductive organs during sexual acts, it is also possible to prevent the unplanned pregnancy and the spread of sexually transmitted diseases.

The primary consideration in this design is to provide a safe device for sex workers to protect against sexually transmitted diseases and prevent sperm from entering the vagina during sexual activity. This safety device is a double-layer elastic film female insurance made of polyethylene, polypropylene, polyester fiber, nylon, polyvinyl chloride, biopolymer, nitrile rubber or other materials in the shape of omega or similar. set.

Double-layered elastic films can be sealed with thermal, chemical, mechanical, optical, electrical or other energy sources. The sealed and joined omega-like film substrate constitutes two extending flanges which are opened to form a cover portion of the condom, and the omega-shaped columnar portion constitutes a female condom with one end sealed and one end opened.

The diameter of the opening part of the female condom is designed to allow the penis to be implanted and rhythmic while the Omega column is sufficient to accommodate the penis. The cover is sufficient to cover the scope of the reproductive organs to prevent penetration of liquids. It can even extend up and down to avoid contact with the genital skin of a sexual partner.

In addition to these specific descriptions, the Omega columnar body can be made into other shapes such as a bell shape, a rectangular shape, or a combination of these.

Another technical feature of the device is that the attachment medium is attached to the outer layer of the cover portion of the film and attached to the release paper. At the same time, you can choose whether to apply full or partial adhesion to the Omega column and the cover.

Any of the films that can be used to secure the mask portion to the vulva can be used as an "attachment medium" or "adhesive medium". It can be electrostatic or industrial adhesives such as polyisoprene, decane, polyacrylate. It can also be a micro-adhesive hydrogel or a non-sticky effect of petrolatum, lanolin, ointment, cream, lotion, ester, honey and syrup. The advantage of the micro-adhesive effect or the non-adhesive effect is that the cover portion can be adjusted even after the film has been attached and not painfully pulled by the pubic hair when peeled off from the female body afterwards. At the same time, the semen is not reversed due to tearing of the film due to excessive pulling.

Another technical feature is the addition of a spermicide or antibacterial agent to the adhesive portion. It can also add nutrients such as vitamins or minerals.

Another technical feature is that it can add or embellish the uneven inside and outside of the columnar body to promote sexual desire, reduce static electricity or promote female narrowing of the vagina, especially suitable for multiple production and vaginal relaxation. Women.

Another design of this design is to design the cover part or Omega column into different shapes, sizes, colors, transparency, texture, and also add patterns, words or signs to enhance the protection effect, beauty and sexuality. .

Another technical feature is that the shape and size of the shield portion or the columnar portion can be made according to the type of the user and the size of the cover portion.

Another technical feature is that the front and rear films of the shield portion can be made into the same or different sizes and shapes according to individual needs.

Another example of this design is that the female condom can be added with a lubricant, flavor or taste to make it look "color and fragrance".

Another example of this design is that the columnar body can be reversed into a male condom.

Another example of this design, the omega-like film is a longitudinal seal that promotes outward and left-side stripping rather than front-to-back stripping.

Another example of this design is that it uses a longitudinal seal to form two columns of double omega-like shapes, making it not limited to vaginal behavior or anal sex.

Another example is that the columnar body is folded longitudinally prior to sealing. This allows the columnar body to achieve a larger storage space in a predetermined space to reduce the tightness and pressure of the beginning of the female condom.

Another example is the lateral folding of the end of the omega column at 5 to 25 mm at the end of the omega column before the double-layer film is sealed so that the end of the omega column has a larger diameter than the beginning. This will make the soft ring at the end acting as a vaginal fixation more secure.

Another model is that the column and cover of the female condom is made up of more than two films. Combined into.

Another model is that the release paper is made of materials that are distinguishable using touch.

The main purpose of this female condom is to cover the vulva/genital organs to provide foolproof protection against sexually transmitted diseases that are infected through sexual activity and to prevent sperm from entering the vagina.

The principle and operation process of this female condom can refer to the following illustration.

Figure 2 illustrates an overview of the manufacturing embodiment of the design embodiment, illustrating the design of the design at low cost and the manner in which it is used. For example, a double-layered elastic film 1 is spread out on a workbench. The thermal energy will make the film sealing machine 3 into an omega or similar shape. One of the above-mentioned "smear-adhesive or adhesive medium machine" 4 is applied to all or part of the mask portion 5 of the upper film, and the release film 6 is covered with a film of the same width. The assembly is turned over so that the attachment medium and the release paper are bonded to the lower layer of the film. Or at the same time, the adhesive medium and the release paper are bonded on the front and back sides of the double-layer film. Another method is to first attach the adhering medium to the release paper and then attach the paste to the film. When the upper and lower layers of the two-layer film have been joined to the attachment medium and the release paper, the assembly is then cut into the final product 10 by means of a compressor or a roller cutter 9. The cutting point of the Omega column is close to the seal, and the bottom of the Omega base forming shield portion 11 is cut vertically or at a specific angle in a straight line or curve.

As mentioned above, the film can be added to the pattern, text, texture, etc. according to personal preference before sealing. The cover portion can also be made into different shapes. In order to make the film easier to peel off, the backing paper can be attached to the inside of the shield portion. Similarly, for this point, the material of the peelable adhesive tape can also be selected from materials having a different touch feeling than the film to make it easy to be distinguished. Other production processes can be made according to the principles of this design and the original intent. For example, the attachment medium or adhesive may be partially or fully covered in the omega column or shield portion. Or the film is cut and attached to the medium and the release paper. Or be sealed by other methods such as laser or electric current.

Prior to sexual activity, the female user 16 can peel off two of the shield portions 11 on the base of the omega as shown in Figures 3a and 3b. The lubricant-loaded middle finger 17 or introducer is then implanted into the open end 13 of the Omega column to the end 14, as shown in Figure 5a. Next, a lubricant-coated omega column is implanted into the vagina 15 as shown in Fig. 4a. When the middle finger 17 or the introducer is still in the vagina, the palm and the other four fingers press the cover portion 11 against the periphery of the reproductive organs, and the other hand peels off the attached release paper 6, as shown in Fig. 5b. The release paper 6 below is also peeled off in the same manner. For easy distinction, the material of the release paper 6 can be different from the film. As shown in Fig. 4b, after the shield portion 11 has been secured to the genital area, the middle finger or introducer can be withdrawn and the Omega column 12 remains in the vagina. The user can implant a soft ring 27 or any fixed device at the end of the Omega column to secure the Omega column in the vagina. If there is a substrate film, it can be removed from the shield at an appropriate time. Stripped.

After the sexual behavior, the cover portion 11 is peeled off from the outer vagina and then the omega column 12 is withdrawn and discarded. Omega or the like, which can refer to the Greek alphabet (Ω) or the Chinese character (convex), refers to the combination of the protruding shape of the Omega column 12 and the extended shape of the shield portion 11.

Figures 6a-c illustrate a model that does not contain release liner attachment. As previously described, it is sealed by a combination of two sheets of elastic film into an omega or similarly shaped seal 18, the sealing seam 2 of which the omega-like substrate forms the extended shield portion 11. The long omega-like portion forms the Omega column 12 of the female condom.

Figure 6b, as previously described, the genitals of the female user 16 are completely covered by the female condom. The female condom start 13 is part of the safe sex and the anal part is covered by the individual. If the anal portion needs to be covered, the rear portion 23 can be expanded during the manufacturing process.

Figure 6c is a stand-up view of the female user 16. As shown in the figure, this female condom is more fixed, more comfortable, and more aesthetic than the female condom described by HESSEL. It is not like HESSEL's design. When standing, the outer ring hangs in the vagina.

Figures 7a-c show screen portions 11 of different shapes. In addition to the elongated shape, it can also be cut 19 into a heart shape. When used, it is like a heart standing in the vagina/pubic bone.

Figure 8a depicts the portion of the vagina/pubis that can be generalized when the base portion constitutes the extended shield portion 11 to cut 19 at a particular angle (Fig. 8b).

Figure 9 depicts the frontal leafed portion and Figure 10 depicts a minimalist template.

Figure 11 depicts the female condom of the Omega column 12 folded longitudinally 20. Such a folding method can increase the space of the Omega column 12, and can reduce the tightness of the opening end when in use.

Figures 13a-b, as discussed above, shortening the posterior portion 23 of the shield portion may not be covered to the anus. The front and rear dimensions of the cover can be made according to the individual's suitability.

Figures 14a-b, the two sheets of film are sealed in a longitudinal direction such that the double-sided substrate of the Omega forms the extended shield portion 11 which can be peeled left and right. This design can be made into double omega columnar bodies 12 and 24, which can be used simultaneously on both vaginal and anal sex.

Figures 15a-b, so if it is a male user, both sexual intercourse and anal sex can be protected.

Figure 16 depicts the implantation of a soft ring 27 to the end of the column to secure it in the vagina. The ends of the columnar bodies of the two-layer film are laterally folded 26 from each other at 5 to 25 mm when sealed, as shown in Figs. 16a and 16b.

In order to facilitate the implantation, the diameter of the soft ring 27 when lying down must be smaller than the width of the column body, but in order to avoid the soft ring falling when the condom is peeled off or during sexual intercourse, the soft ring 27 must be in a vertical manner. Implanted at the end. Sealing the end of the columnar body with the fold 26 allows for ample space to allow the soft ring 27 to be placed in the vertical direction at the end of the columnar body.

In Fig. 17, a female condom can be sealed 18 into an omega column 12 and a shield portion 11 in a multilayer film. Although this design increases the difficulty of production, it can reduce the tightness of the open end in sexual behavior.

This condom can completely block the internal and external parts of the female reproductive organs when properly used, and prevent the exchange of body fluids during the sexual activity of the partner. Because it completely blocks the genital organs, it can be free from vaginal discharge, bleeding or odor. Because of its unique design, it can be used in different occasions such as bathing, bathing, swimming pool, nautical, seaside and oral sex and anal sex without worrying about pollution. Made according to different permeability, it can cover pubic hair, scars, abnormal physiological structures and pigmentation. Because of its lightness in use, it can be worn at any time before sexual activity and removed at any time afterwards. Unlike ordinary condoms, it does not need to be based on the hardness of the penis during sexual intercourse. Because of the uniqueness of the design, the simplicity of the manufacturing process and the ease of use, the thin film is made. Therefore, it has a more sensitive touch and a sense of heat than the previous condom.

The above description is only a preferred embodiment of the present invention, and the scope of the patent application according to the present invention is Equal variations and modifications are intended to be within the scope of the present invention.
