The present invention. generally relates to urinary devices, and more particularly relates to non-invasive urinary devices. Many STP (Stand to Pee) portable urination devices are essentially funnels that share a similar shape and appearance. Typically, the funnel simply encompasses the vulva and directs urine out an exit spout, often resulting in urine leaking onto the wearer due either to insufficient seal, backsplash, or poor fluid dynamics which typically leave the user's vulva wet with mine deposits that require wiping.
Each unique urination attempt requires that the device either be adjusted, re-seated to ensure a seal, or even removed from a separate package and placed into the user's pants—an action that does not appear natural and requires varying levels of exposure. Spouti is the culmination of my efforts to eliminate the need to placement or adjustment with each urination attempt, concerns about leaking, and the need to wipe.
The present invention is an apparatus that satisfies the above needs. A novel, non-invasive, urinary device is described that allows a person with a vagina to urinate in a standing position without requiring the removal of any clothing resulting a urination attempt that transfers no urine to the clothes nor leaves traces of urine between the labia. Spouti will be roughly 30 cm in length with one end protruding slightly into the vaginal canal as it rests between the labia. In its final construction it will be a single unit with exit tubing inserted through the curved section of the funnel and bonded to the inner funnel wall to ensure separation does not occur.
The inlet opening which surrounds the urethral sphincter consists of a smooth elliptical cup that is mounted to a curved funnel and exit tube that works as a direct seal to prevent leakage. Unlike the medicine spoon which also surrounds the urethra, the cylinder body of Spouti uses the vulva to hold the device in place so the wearer does not need to press the device into the tender flesh of the urethral sphincter to achieve a seal. The elliptical shape is more conducive to creating a seal as it is not distorted by lateral pressure from the thighs. Due to the nature of the contact between the elliptical opening and the urethral sphincter the urine flows away from the body and never touches the vulva upon exit.
A generally cylindrical body consisting intersected by a small funnel which seals around the urethra.
A smooth elliptical inlet designed to be positioned around the urethra to maximize comfort and seal. The elliptical shape allows for some variation in the placement of the urethra as well as encourages the fluid dynamics of the funnel.
The small funnel that intersects the body is shaped with a curved section of the funnel which converges with the exit tube. The curved section of the section of the funnel and the flatter section of the funnel directs the mine for maximum flow and minimum backwards pressure.
The exit tube is both curved and flexible. The curve of the exit tube allows inserted extension tubing to come forward and outwards from between the user's legs to minimize kinking if the tube is pulled through the user's pants.
The presented invention is created through a silicone injection process. The initial design was derived from a model created in TinkerCad and cast in molds printed via a non-commercial model 3D printer. The presented device sits in the space between the inner labia and consists of a flat cylindrical body intersected by a funnel shaped cavity with flat wails slanted at a downwards angle. This cavity converges with a curved exit tube that points away from the urethra, into an additional section of silicone tubing that faces forward and away from the body.
The presented invention is inserted between the labia by placing the elliptical inlet over and around the urethral sphincter. When inserted correctly the cylinder body will have the curved exit tubing pointing downwards and away from the body while the clitoris rests above the smooth cylindrical half of the upper portion of the flattened cylindrical body.
During a urination attempt the silicone exit tubing may form a vacuum requiring the user to gently squeeze the tube to allow the remainder of the urine to flow out. Once inserted the presented invention is worn continuously throughout the day and does not require the user to reposition the device when urination is desired.
I hereby state that the submission, filed in accordance with 37 CFR 1 821(g) [or (h)], herein does not include new matter which goes beyond the initial disclosures in the international application.
