Apparatus for collection of urine in females

Claim 2

Apparatus for obtaining from a female a urine specimen which is relatively uncontaminated by labial and vaginal secretions comprising, in combination, a urinary guide having a passageway formed through its base, means formed on said base adapted to register the female urethra with the passageway and seal off the urethra from the vagina, the vaginal vestibule and contiguous parts, and a collector assembly in fluid communication with said guide to collect a urine sample after the initial flow of urine washes the tissue adjacent the urethra orifice, said collector assembly including an entrapment chamber in fluid communication with the end of said urinary passageway remote from the urethra sealing means, a sample chamber, and means responsive to a preselected quantity of urine in said entrapment chamber to cause the urine flow to be transferred into said sample chamber.

Claim 3

Apparatus for obtaining from a female a urine specimen which is relatively uncontaminated by labial and vaginal secretions in accordance with claim 1 wherein said transfer means includes an upwardly sloping passageway between said urine passageway and said sample chamber overlying said entrapment chamber to permit the flow of urine to move interior of said sample chamber after said entrapment chamber is full, and a ball float valve adapted to seat and seal off an air vent between the entrapment chamber and said sloping passageway when said entrapment chamber is full.

Claim 4

Apparatus for obtaining from a female a urine specimen which is relatively uncontaminated by labial and vaginal secretions in accordance with claim 1 wherein said entrapment chamber is disposed interior of said sample chamber concentric to a tubular member which connects said urine passageway to said entrapment chamber, and said transfer means comprises a float assembly slidably mounted on said tubular member for movement between a first position when said tubular member is not in fluid communication with said sample chamber and a second position when said tubular member is in fluid communication with said sample chamber, and means responding to a preselected volume of urine in said entrapment chamber to move said float assembly to said second position whereby urine will thereafter flow into said sample chamber.

Claim 5

Apparatus for obtaining from a female a urine specimen which is relatively uncontaminated by labial and vaginal secretions in accordance with claim 1 and including means to permit urine in excess of that collected in the entrapment and sample chambers to overflow from said collector assembly, and vent means to vent said sample chamber and operable to seal off said overflow means after a urine specimen is obtained.

Claim 6

Apparatus for obtaining from a female a urine specimen which is relatively uncontaminated by labial and vaginal secretions in accordance with claim 1 wherein the transfer means responsive to the preselected quantity Of urine seals off the entrapment chamber so that the urine flowing into said sample chamber cannot be contaminated thereby.

Claim 7

Apparatus for obtaining from a female a urine specimen which is relatively uncontaminated by labial and vaginal secretions in accordance with claim 1 and including overflow means associated with said sample chamber of said collector assembly to permit the urine in excess of the capacity of the entrapment and sample chambers to flow out of said collector assembly, and means operable to seal off said entrapment chamber from said sample chamber.

Claim 8

Apparatus for obtaining from a female a urine specimen which is relatively uncontaminated by labial and vaginal secretions in accordance with claim 5 wherein said entrapment chamber is disposed interior of said sample chamber in open communication with the interior of said sample chamber through an opening in the top of said entrapment chamber, an open funnel is disposed through said opening in the entrapment chamber but spaced apart from the remote end of said urinary guide passageway, a tubular member forming part of said remote part of said urinary guide passageway slidably supported in the top of said sample chamber in axial alignment with the funnel retained in said entrapment chamber, said tubular member adapted to direct the urine flow from said urinary guide into said entrapment chamber until the level of urine therein rises above the lower edge of said funnel to trap a body of air in said entrapment chamber which in turn causes the subsequent flow of urine to overflow the funnel into said sample chamber, and means operable to axially wedge said tubular member into said funnel to seal off said entrapment chamber from said sample chamber.
