Abstract

A midstream urine collector is disclosed having an open-ended funnel-shaped body with a cup mounted therein, the cup having an upwardly-directed mouth over which a cover of water-soluble material extends. The cup is substantially smaller than the flow passage through the body so as to permit the downward flow of urine through the passage past the cup. A deflector in the form of a disc-shaped shield is mounted within the funnel-shaped body above the water-soluble cover to protect the cover against rupture that might otherwise occur if the cover were impacted squarely by a forceful stream of urine as a patient commences voiding into the collector.

Claims

1. A midstream urine collector comprising a funnel-shaped body having a downwardly-tapering wall defining an upper inlet, a lower outlet, and a flow passage therebetween;

a cup member having an upwardly-directed mouth and being mounted within said passage below said inlet;

said cup member being substantially smaller than said passage to permit the downward flow of urine through said passage past said cup member;

a generally dome-shaped cover extending over said cup member formed of a non-contaminating water-soluble polymeric material capable of disintegrating within 2 to 15 seconds upon exposure to a stream of urine; and

deflecting means mounted within said body above said cover for shielding at least an upper portion of said cover against direct impingement by a stream of urine discharged into the inlet of said funnel-shaped body.

10. The collector of claim 1 in which said funnel-shaped body has inner and outer surfaces and is composed of a primary layer of water-soluble material which will dissolve or disperse when disposed in the water of a toilet bowl and a thin protective, but relatively weak, layer of water-insoluble material which lines said inner surface and prevents urine passing through said flow passage from contacting said primary layer;

said cup member having an outer surface which is exposed to said flow passage and an inner surface which defines an interior chamber below an upwardly-directed mouth;

said cup member being composed a primary layer of water-soluble material which forms the outer surface of the cup member and which will dissolve or disperse when disposed in the water of a toilet bowl and a thin protective, but relatively weak, layer of water-insoluble material which lines said inner surface of said chamber.

11. The collector of claim 10 in which said deflecting means comprises a generally disc-shaped shield supported by a support arm having a lower end connected to a collar extending about said cup member;

said shield, arm and collar being primarily formed of water-soluble material having upwardly and outwardly facing surface portions covered by thin layers of water-insoluble material.

2. The collector of claim l in which said deflecting means comprises a generally horizontal disc-shaped shield.

3. The collector of claim 2 in which said shield has a diameter smaller than that of said dome-shaped cover.

4. The collector of claim 2 in which said shield is generally imperforate.

5. The collector of claim 2 in which said shield has openings therethrough.

6. The collector of claim 2 in which said shield is provided with mounting means connected to said cup member.

7. The collector of claim 6 in which said mounting means comprises a support arm having an upper end joined to said shield and a lower end connected to a mounting collar.

8. The collector of claim 7 in which said mounting collar extends about said cup member.

9. The collector of claim 8 in which said mounting collar has a downwardly and outwardly sloping upper surface for deflecting urine away from said cup member.
