Pressurized fluid delivery system

Abstract

A fluid delivery system comprising a first bladder having a first inlet and a first outlet, the first bladder configured to contain liquid, a second bladder capable of being pressurized by inflation and having a second inlet, the second bladder being formed adjacent to the first bladder, such that the first bladder and the second bladder are integrated to form a pressurized fluid reservoir.

1 . A fluid delivery system comprising:
 a) a first bladder comprising a first perimeter, an inner wall surface and an outer wall surface, the first bladder also comprising one or more orifices through which a liquid may pass in and out of the first bladder;   b) a second bladder operably connected to the first bladder such that the first bladder and second bladder work together to form a pressurized fluid reservoir, the second bladder comprising a second perimeter, an inner wall surface and an outer wall surface;   c) one or more first-bladder-access orifices through which a liquid may pass in and out of the first bladder, and at least one port through which the second bladder can be inflated with a pressurized gas;   d) a perimeter seam along a portion of the perimeter of the second bladder.   
     
     
         2 . The system of  claim 1 , wherein the first outer wall surface of the first bladder and the second inner wall surface of the second bladder are in fluid communication. 
     
     
         3 . The system of  claim 1 , wherein the perimeter seam along a portion of the perimeter of the second bladder includes a portion of the first perimeter of the first bladder. 
     
     
         4 . The system of  claim 3 , further comprising one or more structure seams that adjoin the first and second bladders spaced from the perimeter of the second bladder. 
     
     
         5 . The system of  claim 1 , further comprising a first tube in fluid communication with the first bladder and an outlet. 
     
     
         6 . The system of  claim 1 , further comprising a filter operably connected with the first bladder. 
     
     
         7 . The system of  claim 1 , further comprising a compressed gas source operably connected to the second bladder and a valve operable to control inflation of the second bladder. 
     
     
         8 . The system of  claim 7 , wherein the compressed gas source contains argon. 
     
     
         9 . The system of  claim 1 , further comprising a pressurized gas source operably connected to the second bladder and configured to inflate the second bladder when the pressurized gas source is operated. 
     
     
         10 . The system of  claim 9 , wherein the pressurized gas source is configured to compress air into the second bladder. 
     
     
         11 . The system of  claim 4 , further comprising two chambers in fluid communication with one another in the first bladder, wherein the two chambers are separated by a single structure seam. 
     
     
         12 . The system of  claim 11 , wherein the single structure seam is located in approximately the center of the pressurized fluid reservoir which extends in a direction of a length of the pressurized fluid reservoir. 
     
     
         13 . The system of  claim 4 , further comprising a plurality of chambers in fluid communication with one another in the first bladder, wherein the plurality of chambers are separated by a plurality of structure seam elements. 
     
     
         14 . The system of  claim 13 , wherein the plurality of seam elements are in a leaf-shaped configuration located approximately in the center of the pressurized fluid reservoir.
