Patent ID: 7766301

Claim:
An occluder mechanism for occluding at least one collapsible tube carrying a liquid, comprising: an elongated, spring-biased occluding member having a first end and a second end, the first end pivotally mounted to a support structure and the second end linked to an occluder blade having a linking end and an occluding end; and a force actuator arranged and configured to cause transverse deflection of at least a portion of the occluding member between the first end and the second end, reducing the distance between the first end and the second end, wherein the occluding end of the occluder blade is positioned to compress the at least one collapsible tube when the occluding member is in a relaxed position; and the occluding end of the occluder blade is retracted from a position that compresses the collapsible tube when said portion of the occluding member is transversely deflected.
