Detailed Description

Complete technical specification and implementation details from the patent document.

This application claims the benefit of priority to U.S. Provisional Patent Application No. 63/643,118 entitled “PROTECTIVE UNDERGARMENT FOR PREVENTION OF SEXUALLY TRANSMITTED DISEASES AND INFECTIONS,” filed on May 6, 2024, the contents of which are incorporated herein by reference in their entirety for all purposes.

All publications and patent applications mentioned in this specification are herein incorporated by reference in their entirety to the same extent as if each individual publication or patent application was specifically and individually indicated to be incorporated by reference.

Sexually transmitted diseases and infections are communicable health risks prevalent in society and can result in major health problems including disability and death. Many sexually transmitted diseases and infections do not have cures or effective treatments. Problematically, condoms used as a form of protection against such sexually transmitted diseases and infections usually do not extend all the way down to the base of a user's penis and beyond, and may not provide a good seal in the lower regions of a user's penis to serve as a barrier against infection. Furthermore, normal appearing skin of the genital and anal regions may be infected by bacteria, viruses, etc. associated with sexually transmitted diseases and infections which are not visible to the naked eye. This may lead to unsuspected transmission of sexually transmitted diseases and infection during sexual activity via regions of the body that condoms do not protect against such as the base of the penis, scrotum, inguinal region, anal region, etc.

Accordingly, there is a need for user-friendly and comfortable apparatuses that may provide barrier protection over the genital and anal regions of the male anatomy during sexual intercourse to prevent bi-directional infection and transmission of diseases between sexual partners.

In general, described herein are methods and apparatuses for a protective undergarment for the prevention of sexually transmitted disease and infections. According to one example, there is an undergarment constructed from an impermeable material, further having a raised central and cylindrical-shaped extension region with an opening configured to receive a shaft of a user's penis through the opening, and further configured to create a seal between the extension region and a condom placed over the user's penis and the extension region. In certain examples, the extension region may have a cylindrical or circular circumference configured to retain the condom's smooth and cylindrical or circular shape for a strong seal. In this or other examples, and to enhance the strength of the seal, the outer surface of the extension region may be smooth for the condom to better contour over to form a strong seal. Other ways that a strong seal may be achieved include longitudinal ribs or protrusions along the outer surface of the extension region, with an absence of circumferential or transverse ribs or protrusions along the outer surface of the extension region. Having circumferential or transverse ribs or protrusions on the outer surface of the extension region may interfere with the strength and quality of the seal by impeding the contouring of the condom to the outer surface of the extension region.

According to certain examples, the undergarment covers one or more of: a scrotum, buttocks, anus, perineum, inguinal region, and upper thighs of the user.

According to certain examples, a diameter of the opening of the extension region is 1-2 inches in length.

According to certain examples, the opening of the extension region is radially extendible to accommodate variable sizes of the shaft of the user's penis.

According to certain examples, one or more of a length and a thickness of the extension region is increased to bolster girth of the shaft of the user's penis for improvement of one or more of: (i) sexual stimulation and (ii) the seal between the extension region and the condom placed over the user's penis and the extension region.

According to certain examples, the impermeable material is a breathable fabric material, in which the breathable fabric material is configured for user comfort during wear.

According to certain examples, the impermeable material is a latex material.

According to certain examples, the extension region is constructed from an impermeable latex material and other regions of the undergarment are constructed from an impermeable breathable fabric material configured for user comfort during wear, further in which the latex material of the extension region is affixed to the breathable fabric material of the other regions via one or more of: (i) adhesive material, (ii) electro-scaling, and (iii) stitching.

According to certain examples, the extension region is an impermeable breathable fabric material configured for user comfort during wear having added latex material including one or more of: (i) a latex coating, (ii) stitched latex, and (iii) threaded latex, wherein the added latex material is configured to enhance one or more of: (a) stretchability of the extension region, (b) impermeability of the extension region, and (c) the seal between the extension region and the condom placed over user's penis and the extension region.

According to certain examples, the added latex material forms a ridge around the circumference of the extension region.

In certain examples, the latex coating or other material coating of the extension region's outer surface may be configured to create a strong seal with the condom by having a high coefficient of friction with the condom material, which may be latex. The added latex material may form a ridge or other arrangement around the circumference of the extension region to enhance the seal between the condom placed over the user's penis and the extension region and/or the girth of the user's penis.

According to various examples, protective undergarmentmay cover one or more of a user's scrotum, buttocks, anus, perineum, inguinal region, and upper thighs. According to yet other examples, protective undergarmentmay be modified for a female user to cover various parts of the external and internal female anatomy.

In certain examples, protective undergarmentmay be configured to be disposable after use. For example, at least undergarment bodymay be partially or fully constructed from easily removable, degradable, and/or inexpensive materials such as polyester that the user may, for example, tear off from their body after use for disposal.

In yet other examples, protective undergarmentmay be non-disposal and configured for longer use and wear, for example by being constructed at least partially or entirely from materials that are durable, washable, and easily disinfected for reuse. Such materials may include linen, cotton, nylon, microfibers, etc. In some examples, one or more components of protective undergarment, for example components that are most prone to environmental exposure or skin contact such as extension region, may be disposable, whereas undergarment bodymay be reusable.
