Abstract
Abstract A urine collection system for females comprised of a soft, flexible, sealing member forming a seal around the external urethral ostium, by conformation to and adhesion to the tissue surface. A conduit, or drain, passes through the sealing member leading to collection and storage means for the urine. A positioning or orientation member is provided to achieve alignment of the conduit lumen through the sealing member with the urethral orifice.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
191 words
An enclosed, self-contained female urine collection system which can be worn for extended periods of time and which avoids the necessity for catheterization, whereby transurethral transport of micro-organisms are avoided, or minimized, said system comprised of in combination: (a) a flexible conduit for conducting urine from the urethral ostium to a urine collection and storage zone, said conduit having an internal diameter essentially the same as the urethra, and said conduit having disposed therein a movable, urethral positioning member whereby said conduit can be axially aligned with said urethral ostium, (b) a support member affixed to and circumferentially encompassing one end of said conduit and having disposed thereon a pliable, adhesive sealing medium whereby the lumen of said conduit can be sealably positioned in alignment with the ostium of said urethra using said urethral positioning member and whereby said conduit does not penetrate said urethra, but is maintained in a leak-free relationship therewith so that urine can flow from said urethral ostium through said conduit to said collection and storage zone, and (c) said urine collection and storage zone located at a point on said conduit distant from said urethral ostium.
Claim 2
Dependent Claim
191 words
An enclosed, self-contained female urine collection system which can be worn for extended periods of time and which avoids the necessity for catheterization, whereby transurethral transport of micro-organisms are avoided, or minimized, said system comprised of in combination: (a) a flexible conduit for conducting urine from the urethral ostium to a urine collection and storage zone, said conduit having an internal diameter essentially the same as the urethra, and said conduit having disposed therein a movable, urethral positioning member whereby said conduit can be axially aligned with said urethral ostium, (b) a support member affixed to and circumferentially encompassing one end of said conduit and having disposed thereon a pliable, adhesive sealing medium whereby the lumen of said conduit can be sealably positioned in alignment with the ostium of said urethra using said urethral positioning member and whereby said conduit does not penetrate said urethra, but is maintained in a leak-free relationship therewith so that urine can flow from said urethral ostium through said conduit to said collection and storage zone, and (c) said urine collection and storage zone located at a point on said conduit distant from said urethral ostium.
Claim 3
Dependent Claim
