Abstract:
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 clamp for selectively engaging and disengaging a mating element resiliently received by the resilient clamp; wherein the resilient clamp comprises a pair of spaced, opposed jaws spanning a recess therebetween for receiving the mating element within the recess between the pair of jaws to transfer sufficient lateral force from the mating element to the shuttle member for sliding actuation thereof from the first configuration to the second configuration, wherein the pair of jaws deflect outwardly during reception of the mating element between the pair of jaws.
