Powered hydration system

1. A portable hydration system, comprising:

an outer bag;

a fluid reservoir for containing a volume of a potable fluid removably received within said outer bag, said fluid reservoir having a fluid outlet;

a pump received within said outer bag, said pump having an inlet and an outlet, said pump inlet being in fluid communication with said reservoir outlet, said pump outlet including a nozzle extending through an opening in said outer bag;

one or more sealing members for sealing said opening in said outer bag relative to said pump outlet;

a dispensing tube coupled to said pump outlet and defining a fluid passageway for supplying fluid to a user;

a switch mounted on said dispensing tube in electrical communication with said pump, said switch for selectively actuating and deactuating said pump; and

a wire passing within said fluid passageway and electrically coupling said pump with said switch.

2. The portable hydration system of claim 1 , wherein said outer bag and said dispensing tube are resistant to environmental contamination.

3. The portable hydration system of claim 2 , further comprising:

said outer bag is formed of a material which is resistant to one or both of chemical agents and biological agents; and

said dispensing tube is formed of a material which is resistant to one or both of chemical agents and biological agents.

4. The portable hydration system of claim 1 , wherein said switch is resistant to environmental contamination.

5. The portable hydration system of claim 4 , said switch is resistant to one or both of chemical agents and biological agents.

6. The portable hydration system of claim 1 , further comprising:

a fastener for releasably sealing an open end of said outer bag.

7. The portable hydration system of claim 1 , further comprising:

a length of tubing fluidically coupling said pump inlet and said reservoir outlet.

8. The portable hydration system of claim 7 , further comprising:

said length of tubing having a first end having a first fluid connector and a second end attached to said pump inlet; and

a reservoir outlet having a second fluid connector, said first and second fluid connectors adapted to be releasably connected to define a flow passageway therethrough.

9. The portable hydration system of claim 1 , further comprising:

said outer bag having an open end adapted to be sealed by one or both of folding and rolling said open end over upon itself; and

a fastener removably attachable to said outer bag for securing said outer bag in a sealed condition.

10. The portable hydration system of claim 1 , further comprising:

a user-actuatable valve located at a distal end of said dispensing tube.

11. The portable hydration system of claim 10 , wherein said user-actuatable valve is a bite valve.

12. The portable hydration system of claim 10 , further comprising:

said user-actuatable valve is detachable from said dispensing tube; and

a filtration member removably attachable to the distal end of said dispensing tube.

13. A hydration method, comprising:

providing a hydration system, said hydration system including:

an outer bag;

a fluid reservoir for containing a volume of a potable fluid removably received within said outer bag, said fluid reservoir having a fluid outlet;

a pump received within said outer bag, said pump having an inlet and an outlet, said pump inlet being in fluid communication with said reservoir outlet, said pump outlet including a nozzle extending through an opening in said outer bag;

one or more sealing members for sealing said opening in said outer bag relative to said pump outlet; and,

a dispensing tube coupled to said pump outlet and defining a fluid passageway for supplying fluid to a user; a switch mounted on said dispensing tube in electrical communication with said pump, said switch for selectively actuating and deactuating said pump; and

a wire passing within said fluid passageway and electrically coupling said pump with said switch;

at least partially filling said fluid reservoir with a potable fluid; and

operating said pump to deliver the potable fluid from said fluid reservoir through said dispensing tube and to a mouth of a user.

14. The method of claim 13 , wherein said outer bag and said dispensing tube are resistant to environmental contamination.

15. The method of claim 13 , further comprising:

said outer bag is formed of a material which is resistant to one or both of chemical agents and biological agents; and

said dispensing tube is formed of a material which is resistant to one or both of chemical agents and biological agents.

16. The method of claim 13 , wherein said pump is operated by actuating said switch by the user on said dispensing tube and electrically coupled to said pump.

17. The method of claim 16 , wherein said switch is resistant to any one or more of: environmental contamination, chemical agents, and biological agents.

18. A portable hydration system, comprising:

an outer bag;

a fluid reservoir for containing a volume of a potable fluid removably received within said outer bag, said fluid reservoir having a fluid outlet;

a pump received within said outer bag, said pump having an inlet and an outlet, said pump inlet being in fluid communication with said reservoir outlet, said pump outlet including a nozzle extending through an opening in said outer bag;

one or more sealing members for sealing said operating in said outer bag relative to said pump outlet;

a dispensing tube coupled to said pump outlet and defining a fluid passageway for supplying fluid to a user;

said nozzle including a flange adjacent an interior surface of said outer bag and a conduit portion extending from the flange through the opening in the outer bag;

a clamping ring attached to the flange, said clamping ring circumscribing the conduit portion adjacent an exterior facing surface of said outer bag to provide a clamping engagement between the clamping ring, the outer bag, and the flange;

said one or more sealing members disposed between one or both of:

the flange and the interior surface of the outer bag; and

the clamping ring and the exterior facing surface of said outer bag.
