Liquid pump and related systems and methods

Abstract

Liquid pumps and related systems and methods are generally described.

What is claimed is: 
     
         1 . A device, comprising:
 a first leaf comprising a rigid surface, a deformable surface, and a space between the rigid surface and the deformable surface; and   a second leaf connected to the first leaf;   wherein the first leaf and the second leaf define a cavity into which a deformable, liquid-containing reservoir can be positioned.   
     
     
         2 . The device of  claim 1 , further comprising a deformable, liquid-containing reservoir within the cavity. 
     
     
         3 . The device of  claim 1 , further comprising a port fluidically connecting a source of a working fluid to the space between the rigid surface and the deformable surface. 
     
     
         4 . The device of  claim 2 , further comprising a port fluidically connecting a source of a working fluid to the space between the rigid surface and the deformable surface. 
     
     
         5 . The device of  claim 1 , wherein the second leaf comprises a second rigid surface, a second deformable surface, and a second space between the second rigid surface and the second deformable surface. 
     
     
         6 . The device of  claim 2 , wherein the second leaf comprises a second rigid surface, a second deformable surface, and a second space between the second rigid surface and the second deformable surface. 
     
     
         7 . The device of  claim 3 , wherein the second leaf comprises a second rigid surface, a second deformable surface, and a second space between the second rigid surface and the second deformable surface. 
     
     
         8 . The device of  claim 4 , wherein the second leaf comprises a second rigid surface, a second deformable surface, and a second space between the second rigid surface and the second deformable surface. 
     
     
         9 . A method of expelling liquid from a deformable reservoir positioned between a first leaf and a second leaf, the method comprising:
 transporting a working fluid into a space between a rigid surface of the first leaf and a deformable surface of the first leaf such that the volume of the space is expanded and liquid is expelled from the deformable reservoir.   
     
     
         10 . The method of  claim 9 , wherein the working fluid is transported into the space via a port in the first leaf. 
     
     
         11 . The method of  claim 9 , wherein the second leaf comprises a second rigid surface, a second deformable surface, and a second space between the second rigid surface and the second deformable surface. 
     
     
         12 . The method of  claim 10 , wherein the second leaf comprises a second rigid surface, a second deformable surface, and a second space between the second rigid surface and the second deformable surface. 
     
     
         13 . The method of  claim 11 , wherein the working fluid is a first working fluid, and further comprising transporting a second working fluid into the second space such that the volume of the second space is expanded. 
     
     
         14 . The method of  claim 12 , wherein the working fluid is a first working fluid, and further comprising transporting a second working fluid into the second space such that the volume of the second space is expanded.
