Female urinary device
An external female urinary device includes a connecting and urine collecting component (CUCC) and a urine directing and discharging component (UDCC) configured to connect with the CUCC. The CUCC tapers from a larger orifice to a smaller orifice. The CUCC has a ring defining the larger orifice. The ring is made of a material capable of adhering to urethral orifice surrounding skin (UOSS) as well as to the inner facing surfaces of the labia minora and/or the labia majora after the CUCC is pressed against that UOSS. The ring remains adhered to the UOSS without requiring an external force for keeping the ring in contact with that skin.
1. A urine collection device comprising:
a urine collecting component (UCC) comprising a hollow funnel having a larger upper orifice and a smaller lower orifice, the hollow funnel tapering from the upper orifice to the lower orifice; and
a urine discharging component (UDC) comprising a hollow tube adapted to communicate with the lower orifice of the UCC and provide a continuous duct for passage and discharge of urine from the UCC, wherein
the UCC further comprises a margin ring that defines the upper orifice, the margin ring having a crescent shape characterized by a back side peak and a front side peak, the back side peak extending a first vertical distance from the lower orifice and the front side peak extending a second vertical distance from the lower orifice, the first vertical distance being greater than the second vertical distance,

an outer surface of the UCC is formed from a semi-rigid, smooth surface viscoelastic material having a surface tension equivalent to or less than that of skin such that, upon the UCC being pressed against the labia minora and/or the labia majora while the labia minora and/or the labia majora is in a moistened state and then releasing such pressing force, the outer surface of the UCC will remain adhered to an inner wall of the labia minora and/or the labia majora without an adhesive.
4. The urine collection device of claim 1 , wherein
the UCC is dimensioned such that, upon being inserted within the labia majora and the labia minora, the UCC is further retained in position by exertion of a closing-in force on the UCC by inner walls of the labia majora and/or inner walls of the labia minora.
5. The urine collection device of claim 1 , wherein
the back side peak of the margin ring is adapted for insertion into the vaginal orifice for positioning the upper orifice of the margin ring to circumscribe the urethral orifice.

the viscoelastic material that adheres to the internal skin of the vulva is a biocompatible silicone based material or a biocompatible polytetrafluoroethylene based material.
7. The urine collection device of claim 1 , wherein
the UCC and the UDC are adapted to retain their spatial configurations relative to one another upon the UCC being adhered to moistened internal skin of the vulva.
8. The urine collection device of claim 1 , wherein
the UCC and the UDC are a single entity structure.
9. The urine collection device of claim 1 , wherein
the margin ring of the UCC comprises a substantially horizontal flat contact surface for pressing against the UOSS, the flat contact surface being substantially perpendicular to a substantially vertical upper edge of an outer wall of the hollow funnel.
10. The urine collection device of claim 1 , wherein
the urine collection device excludes support structures adapted for applying an external force for keeping the margin ring pressed against the UOSS.
11. The urine collection device of claim 1 , further comprising:
a flexible and resilient skirt connected to and surrounding the UCC, the skirt being connected to an approximate middle region of an outer surface of the UCC, the outer surface of the UCC tapering between the larger upper orifice and the smaller lower orifice of the hollow funnel, the skirt having an oval shape and tapering from a smaller circumference at a point where the skirt is connected to the UCC to a larger circumference at a lower free end of the skirt.
12. The urine collection device of claim 11 , wherein
the skirt is formed from a semi-rigid, smooth surface viscoelastic material having a surface tension equivalent to or less than that of skin such that, upon the skirt being pressed against the internal skin while the internal skin is in a moistened state and then releasing such pressing force, the skirt will remain adhered to the internal skin without an adhesive.
13. The urine collection device of claim 1 , wherein
the UCC is configured such that, upon insertion into the vulva of a female user, the back side peak of the margin ring is positioned to abut an anterior wall of the vagina.
14. A method of using the urine collection device of claim 1 , comprising:
inserting the UCC into the vulva of a female user, with the margin ring positioned within the labia minora and the upper orifice of the margin ring circumscribing the urethral orifice; and
pressing the margin ring against the UOSS, while the UOSS is in a moistened state, so as to generate an adhesion force between the margin ring and the UOSS, such that upon releasing the pressing force the margin ring remains adhered to the UOSS without an adhesive.
15. The method according to claim 14 , further comprising:
before inserting the UCC into the vulva, applying a biocompatible wetting-agent to the margin ring of the UCC and/or an internal skin surface of the vulva.
