1. A liquid infusion apparatus, comprising:

  • a liquid conduit comprising a proximal segment, a distal segment and an intermediate segment therebetween, the intermediate segment having a flexible elastic tubular member of selected cross-sectional dimensions;

    a fluid connector in fluid communication with the proximal and intermediate segments; and

    a flow valve in fluid communication with the intermediate and distal segments, the flow valve comprising a shuttle member slidably disposed within a housing about the distal segment, the shuttle member being configured for lateral movement relative to an elongated axis of the distal segment, the shuttle member being configured to operate in a first configuration to impede fluid flow through the liquid conduit and in a second configuration for which fluid flow through the liquid conduit is unimpeded, the shuttle member comprising a resilient grasper for selectively engaging and disengaging a mating actuator resiliently received by the grasper;

    wherein the resilient grasper comprises a pair of spaced, opposed jaws spanning a recess therebetween for engaging the mating actuator within the recess between the pair of jaws to transfer sufficient lateral force from the mating actuator to the shuttle member for sliding actuation thereof from the second configuration to the first configuration.
