Ring shaped hydration tube

Abstract

A personal hydration system is disclosed. The personal hydration system may include a body configured to form a loop around a user's torso. The body may define a cavity configured to contain fluid. The personal hydration system may include a tube in fluidic communication with the cavity. The personal hydration system may include a fluid seal coupled to the tube and configured to selectively allow fluid to pass through the tube.

What is claimed is: 
     
         1 . A personal hydration system comprising:
 a body configured to form a loop around a user's torso, the body defining a cavity configured to contain fluid;   a tube in fluidic communication with the cavity; and   a fluid seal coupled to the tube and configured to selectively allow fluid to pass through the tube.   
     
     
         2 . The personal hydration system of  claim 1 , wherein the body has an adjustable circumference. 
     
     
         3 . The personal hydration system of  claim 1 , wherein the body further comprises an outer sheath coupled to an inner bladder that defines the cavity, and the outer sheath is configured to form a complete loop around the user's torso. 
     
     
         4 . The personal hydration system of  claim 1 , further comprising a fluid port in fluidic communication with the cavity, and the tube couples to the fluid port. 
     
     
         5 . The personal hydration system of  claim 1 , wherein the tube has a first end and a second end opposite the first end, the first end of the tube being configured to be disposed outside of the body, the second end of the tube extending within the cavity and being configured to be in fluidic communication with the cavity. 
     
     
         6 . The personal hydration system of  claim 1 , wherein the tube includes a first set of barbs located at a first end of the tube and a second set of barbs located at the second end of the tube. 
     
     
         7 . The personal hydration system of  claim 1 , further comprising a set of straps coupled to the body. 
     
     
         8 . A personal hydration system comprising:
 a body configured to form a loop, the body having a bladder that is configured to form at least part of the loop, the bladder having an interior chamber configured to contain fluid and a fluid port in fluidic communication with the interior chamber; and   a fluid seal in fluidic communication with the interior chamber and configured to selectively allow fluid to pass through the fluid port.   
     
     
         9 . The personal hydration system of  claim 8 , wherein the bladder forms a complete loop. 
     
     
         10 . The personal hydration system of  claim 9 , wherein the interior chamber forms a continuous chamber. 
     
     
         11 . The personal hydration system of  claim 8 , further comprising a tube having a first end and a second end, the first end being coupled to the fluid seal, the second end being coupled to the fluid port. 
     
     
         12 . The personal hydration system of  claim 11 , wherein the second end of the tube extends within the interior chamber of the bladder. 
     
     
         13 . The personal hydration system of  claim 8 , further comprising a second fluid seal in fluidic communication with the interior chamber of the bladder and configured to selectively allow fluid to pass through a second fluid port. 
     
     
         14 . The personal hydration system of  claim 8 , wherein the body includes an outer sheath that has an adjustable circumference. 
     
     
         15 . A personal hydration system comprising:
 a body configured to form a loop, the body having a bladder configured to contain fluid, the bladder having a first end, a second end opposite the first end, an interior chamber, a flexible side wall that surrounds the interior chamber, and a fluid port in fluidic communication with the interior chamber, the first end being configured to couple to the second end;   a tube having a first end and a second end opposite the first end, the first end of the tube configured to be in fluidic communication with the interior chamber of the bladder; and   a cap configured to couple to the fluid port and form a fluid-tight seal.   
     
     
         16 . The personal hydration system of  claim 15 , wherein the first end of the bladder is removably coupled to the second end of the bladder. 
     
     
         17 . The personal hydration system of  claim 15 , wherein the body includes an outer sheath. 
     
     
         18 . The personal hydration system of  claim 17 , further comprising an insulating sheath disposed between the bladder and the outer sheath. 
     
     
         19 . The personal hydration system of  claim 15 , further comprising a manual pump coupled to the bladder and configured to pressurize the interior chamber to facilitate easier extraction of fluid. 
     
     
         20 . The personal hydration system of  claim 15 , further comprising a vent valve coupled to the body, the vent valve being configured to allow air to enter into the body while preventing fluid from exiting the vent valve.
