1. A cassette for engagement with an infusion pump for delivery of a fluid to a subject comprising:

  • a housing having first and second ends for holding flexible tubing through which the fluid is directed, the tubing is configured for engaging a pumping mechanism of an infusion pump that moves the fluid through the tubing;

    an anti-flow valve mechanism that is biased against the tubing in a fluid non-delivery position to prevent flow therethough;

    a member operatively associated with the anti-flow valve mechanism to overcome the force-applying member bias to allow flow of fluid through the tubing when the housing is engaged with the pump; and

    the housing is configured and dimensioned for engagement with the infusion pump, wherein during or after engagement the member assumes a fluid delivery position to allow flow of the fluid through the tubing, while before or as the cassette is removed from the pump, the member assumes the fluid non-delivery position to prevent flow of fluid through the tubing.
