  • CONTINUOUS FLUID DELIVERY SYSTEM AND METHOD
    Publication number: 20150273137
    Abstract: The continuous fluid delivery systems includes a fluid pumping device comprising a pump housing comprising a base member with a plurality of inlet ports and at least one outlet port and at least two pairs of opposing pistons movably associated with the housing. Each pair of opposing pistons at least in part defines a respective pumping chamber of the fluid pumping device. The pistons in each pair of opposing pistons may be independently controlled such that any one of the plurality of inlet ports or the at least one outlet port is independently selectable to be in fluid communication with one of the respective pumping chambers. A drive system may be interfaced with the respective pistons to at least reciprocally operate the pistons relative to the base member. The pump housing and the at least two pairs of opposing pistons may comprise a disposable unit.
