Fluid flow occluder and methods of use for medical treatment systems
First Claim
1. An automated peritoneal dialysis system comprising:
- a reusable cycler that is constructed and arranged for coupling to a disposable fluid handling cassette containing at least one pumping chamber, whereinthe disposable fluid handling cassette is configured to be connected in fluid communication with a peritoneum of a patient via a first collapsible tube and with a second source and/or destination via a second collapsible tube; and
an occluder configured and positioned within the cycler to selectively occlude the first collapsible tube while not occluding the second collapsible tube,wherein the occluder comprises;
first and second opposed occluding members comprising spring plates pivotally connected together at opposite first and second ends;
a tube contacting member connected to, or comprising at least a portion of, at least one of the first and second occluding members; and
a single force actuator constructed and positioned to apply a force sufficient to bend both the first and second occluding members,wherein upon application of the force by the force actuator to bend the first and second occluding members, the tube contacting member moves between a tube occluding and an open position.

Abstract
An occluder, and methods for occlusion, that employs first and second opposed occluding members associated with each other, a tube contacting member connected to, or comprising at least a portion of, at least one of the first and second occluding members, and a force actuator constructed and positioned to apply a force to at least one of the first and second occluding members. Application of the force by the force actuator may cause the tube contacting member to move between a tube occluding and an open position. A release member may be configured and positioned to enable an operator to manually move the tube contacting member from the tube occluding position to the open position even with no force applied to the at least one of the first and second occluding members by the force actuator. In one embodiment, the force actuator may apply a force sufficient to bend both the first and second occluding members, so that upon application of the force by the force actuator (such as an air bladder), the first and second occluding members (e.g., spring plates pivotally connected at opposite ends) bend and the tube contacting member may move between the tube occluding and the open position.
