Patent ID: 7651010

Claim:
A multiple-fluid sourcing assembly, comprising: first and second container members containing first and second fluids, respectively; first and second conduits in respective fluid communication with the first and second container members to allow the fluids to pass therethrough; a mounting member to which the first and second containers are mounted such that the first and second conduits are disposed at a predetermined spacing from each other; wherein the first conduit comprises a first compressible portion and a first downstream valve in the first conduit disposed downstream of the first compressible portion and configured to allow the first fluid to flow substantially only downstream of the first downstream valve, the first compressible portion being resiliently compressible such that fluid therein is forced downstream through the first downstream valve when the first compressible portion is compressed, with the first compressible portion being resiliently biased towards an uncompressed state to draw the first fluid into the first compressible portion when the first compressible portion is decompressed; wherein the second conduit comprises a second compressible portion that is compressible to pump the second fluid therethrough from the second container member; and a pumping mechanism which comprises a pumping member disposed between the first and second compressible portions, wherein the pumping member is configured to rotatably engage the compressible portions and to alternatively compress all of the compressible portions simultaneously and then decompress all of the compressible portions simultaneously so that a consistent amount of fluid is pumped through each of the compressible portions during each compression.
