Portable urinal systems and methods of collecting urine

1. A portable urinal system comprising:

a handheld urinal comprising

a neck assembly configured to receive urine from the urethral opening of a user and including a user operated neck valve assembly that when in a normal closed position prevents urine flow through the neck assembly, and when opened by a user permits urine to flow through the neck assembly,

a urinal cup coupled to the neck assembly so that upon use of the urinal and opening of the neck valve assembly by the user, urine flows through the neck assembly into the urinal cup;

a reservoir having a larger volume than the urinal cup comprising

a lid assembly including a substantially rigid spout assembly configured to receive the neck assembly of the urinal such that the configuration of the neck assembly inserted into the spout assembly prevents spillage of urine transferred from the urinal to the reservoir, and

a reservoir cup configured to store urine received from the urinal via the spout assembly.

2. The system of claim 1 , wherein the system lacks an elongated corrugated connection between the urinal neck assembly and the lid assembly of the reservoir.

3. The system of claim 1 , wherein the neck assembly is substantially rigid.

4. The system of claim 1 , wherein the lid assembly comprises a spout valve assembly associated with the spout assembly and wherein the spout valve assembly is operated by coupling the urinal to the reservoir and by applying manual pressure on the urinal towards the reservoir cup causing the neck valve assembly and the spout valve assembly to open simultaneously.

5. The system of claim 1 , wherein the neck valve assembly comprises a sleeve housing a valve plunger, the valve plunger being biased to a valve closed position.

6. The system of claim 1 , wherein the neck valve assembly comprises a retainer cap preventing disassembly of the neck valve assembly without turning the retainer cap.

7. The system of claim 1 , wherein the urinal is sized in volume to receive about 400 to about 600 ml of urine, and wherein the reservoir is sized in volume to store at least about 1600 to about 6000 ml of urine.

8. The system of claim 1 , wherein the urinal neck assembly includes a releasably detachable adapter configured to receive urine from the urethral opening of a female when attached; and allows for the neck assembly to couple to the lid assembly when detached.

9. The system of claim 1 , wherein the urinal neck assembly is adapted for male use.

10. The system of claim 1 , wherein the neck assembly and urinal cup are releasably coupled.

11. The portable urinal system of claim 1 , wherein

the neck assembly has an upper section configured to receive urine from the urethral opening of the user, a middle section having a sleeve which houses a user operated sliding plug valve, and a lower section having an outlet and a plurality of coupling elements, and

the urinal cup coupled to the neck assembly via the plurality of complementary coupling elements.

12. A method of collecting urine with a portable urinal system, the method comprising:

providing a portable urinal system comprising

a handheld urinal comprising

a neck assembly configured to receive urine from the urethral opening of a user and including a user operated neck valve assembly permitting urine to flow through the neck assembly,

a urinal cup coupled to the neck assembly so that upon use of the urinal and operation of the neck valve assembly by the user, urine flows through the neck assembly into the urinal cup;

a reservoir having a larger volume than the urinal cup comprising

a lid assembly including a substantially rigid spout assembly and the lid assembly configured to releasably couple to the neck assembly of the urinal, and

a reservoir cup configured to store urine received from the urinal via the spout assembly;

positioning the handheld urinal to receive urine from the urethral opening of a user;

releasing urine into the neck assembly while opening the valve assembly and allowing urine to collect into the urinal cup;

closing the valve assembly after urination;

coupling the neck assembly of the handheld urinal to the lid assembly of the reservoir;

transferring urine collected in the urinal cup to the reservoir cup by opening both the neck valve assembly and the lid assembly such that urine collected in the urinal cup drains into the reservoir cup.

13. The method of claim 12 , wherein the neck valve assembly comprises a sleeve housing a sliding valve plunger, the valve plunger being biased to a valve closed position.

14. The method of claim 12 , wherein the portable urinal system lacks an elongated corrugated connection between the urinal neck assembly and the lid assembly of the reservoir.

15. The method of claim 12 , wherein the urinal comprises a neck assembly that is substantially rigid.

16. The method of claim 12 , wherein the urinal is sized in volume to receive about 400 to about 600 ml of urine, and wherein the reservoir is sized in volume to store at least about 1600 to about 6000 ml of urine.

17. The method of claim 12 , wherein the neck assembly includes a releasably detachable adapter configured to receive urine from the urethral opening of a female when attached; and allows for the neck assembly to couple to the lid assembly when detached.

18. The method of claim 12 , wherein the neck assembly is adapted for male use.

19. The method of claim 12 , wherein the lid assembly comprises a spout valve assembly associated with the spout assembly and wherein the spout valve assembly is operated by coupling the urinal to the reservoir and by applying manual pressure on the urinal towards the reservoir cup causing the neck valve assembly and the spout valve assembly to open simultaneously.
