Claim 7

The invention of claim 5 wherein the pad comprises: an elongated mass of an absorbent material; and an elastic mesh tube disposed around to cover the absorbent material, said mesh tube defining the first and second ends of the pad, and effective to generate a gentle, even pressure to hold the urinary drainage device in place.

Claim 8

The invention of claim 1 wherein the tube is oval in cross-section and the posterior and anterior ends are situated at opposite ends of a major axis of the oval tube.

Claim 9

A noninvasive urinary drainage device for a female user comprising: a resilient, elastomeric urinary catheter which terminates at one end in a slanted tip section shaped to seal around the urethral orifice of the user; a resilient, elastomeric, substantially circular, plate-like disc secured to the catheter adjacent the tip such that the circular disc surrounds the catheter, said circular disc shaped to mechanically engage the labia minora of the user and defining upper and lower parallel, planar surfaces co-extensive with the circular disc such that the circular disc is foldable and conformable to the anatomy of the user, without reinforcing ridges; a resilient, elastomeric, oval, plate-like disc secured to the catheter adjacent the circular disc such that the oval disc surrounds the catheter and the circular disc is interposed between the tip section and the oval disc, said oval disc positioned offset on a major axis of the oval disc and said oval disc shaped to mechanically engage the labia majora of the user, said oval disc defining upper and lower parallel, planar surfaces co-extensive with the oval disc such that the oval disc is foldable and conformable to the anatomy of the user, without reinforcing ridges; said tip section defining a posterior end and an anterior end, said posterior end extending farther from the circular disc than the anterior end and said catheter oriented such that the posterior and anterior ends of the tube are oriented along the major axis and the posterior end is situated nearer the perimeter of the oval disc than is the anterior end; an elongated, disposable, elastic, absorbent pad which defines an indentation sized to removably receive the oval disc, a passage within the recess positioned to receive the catheter, and first and second ends adapted for connection to a sanitary belt, said pad providing a gentle, even pressure holding the circular and oval discs in place; said pad shaped and configured to hold the circular and oval discs in engagement with the labia minora and majora of the user, respectively, and the tip section of the catheter in sealing relationship with the urethral region of the user in a noninvasive manner.

Claim 10

A noninvasive urinary drainage device for a female user comprising: a resilient, elastomeric urinary catheter which terminates at one end in a slanted tip section shaped to seal around the urethral orifice of the user; a resilient, elastomeric, substantially circular, plate-like disc secured to the catheter adjacent the tip such that the circular disc surrounds the catheter, said circular disc shaped to mechanically engage the labia minora of the user and defining upper and lower parallel, planar surfaces co-extensive with the circular disc such that the circular disc is foldable and conformable to the anatomy of the user, without reinforcing ridges; a resilient, elastomeric, oval, plate-like disc secured to the catheter adjacent the circular disc such that the oval disc surrounds the catheter and the circular disc is interposed between the tip section and the oval disc, said oval disc positioned offset on a major axis of the oval disc and said oval disc shaped to mechanically engage the labia majora of the user, said oval disc defining upper and lower parallel, planar surfaces co-extensive with the oval disc such that the oval disc is foldable and conformable to the anatomy of the user, without reinforcing ridges; said tip section defining a posterior end and an anterior end, said posterior end extending farther from the circular disc than the anterior end and said catheter oriented such that the posterior and anterior ends of the tube are oriented along the major axis and the posterior end is situated nearer the perimeter of the oval disc than is the anterior end; an elongated, disposable, elastic, absorbent pad which defines an indentation sized to removably receive the oval disc, a passage within the recess positioned to receive the catheter, and first and second ends adapted for connection to a sanitary belt, said pad providing a gentle, even pressure holding the circular and oval discs in place; said pad shaped and configured to hold the circular and oval discs in engagement with the labia minora and majora of the user, respectively, and the tip section of the catheter in sealing relationship with the urethral region of the user in a noninvasive manner.

Claim 11
