1. A hand-held pump system, the system comprising:

  • a pumping portion comprising;

    a first channel comprising at least two compressible channels, each of the compressible channels adapted to create a separate fluid flow; and

    a housing;

    a rotor disposed in the housing and having a helical scroll engaged with the compressible channels, the helical scroll comprising;

    a first portion having an increasing radius along a first length of the rotor in the direction of fluid flow, the radius increasing from a first end of the rotor to a maximum value; and

    a second portion having a constant radius along a second length of the rotor, the helical scroll compresses the compressible channels in a peristaltic manner to capture and move fluid along the compressible channels; and

    a slot formed in the housing, the slot including a transverse portion, the fluid port receivable into the slot and secured into the transverse portion of the slot by rotation of the pumping portion relative to the drive portion.
