An occlusion assembly for compressing at least one tube, e.g. a pair of side-by-side flexible tubes, that comprises an occluding member for each tube placed within the assembly. Each occluding member is pressed into an occluding position by an element that is movable, e.g. in a space between the occluding members, to cause a tube-contacting portion of each occluding member to translate toward its associated tubing to compress it. In an embodiment, the element is a spreader that is positioned between two occluding members and acts to spread the distal ends of the occluding members away from each other as they press against their respective tubes. A main spring may be included that urges the spreader toward the distal ends of the occluding elements into an occluding position. The spreader may be moved against the biasing force of the main spring to move the occluding members into a non-occluding position near the proximal ends of the occluding elements, for example manually through a button ...

Occlusion assemblies facilitating occlusion of flexible tubing are disclosed. Occlusion assemblies may be associated with or form part of a medical infusion device and may facilitate fluid handling by such devices. Occlusion assemblies may position and immobilize tubing. Occlusion assemblies comprise a tubing occluder constructed and positioned to apply a force to tube(s) to occlude the tubes. Occlusion assemblies may be configured to include a single tube in certain cases, and in other cases to occlude multiple tubes, whether an odd number of tubes or an even number of tubes. Occlusion assemblies may include automatic actuators and in certain cases also include a manual actuator to provide an override function. Occlusion assemblies may include safety features, for example, to prevent a release of occlusion force on the tubing and/or convenience features, for example a retainer mechanism to hold the tube occluder in a non-occluding position. 1. An occlusion assembly for occluding at least one pair of collapsible tubes of a medical infusion device , comprising:for each pair of collapsible tubes, a first occluding member and a second occluding member, the first occluding member positioned adjacent to a first collapsible tube of the pair and the second occluding member positioned adjacent to a second collapsible tube of the pair, when the tubes are installed in the occlusion assembly for operation, the first occluding member and the second occluding member being further positioned adjacent from each other such that a space is defined between the first occluding member and the second occluding member, the space being on an opposite side of each occluding member than is the collapsible tube to which it is adjacent;a spreader positioned within the space and movable within the space from a first position to a second position, wherein movement from the first position to the second position causes the spreader to force at least a portion of the first and second occluding ...

Described herein are the occlusion assemblies configured to facilitate the opening and closing by occlusion of flexible tubing. In particular embodiments, the occlusion assemblies are associated with or form part of a medical infusion device, such as a hemodialysis device, peritoneal dialysis device, plasmapheresis device, etc., and may be controllably and automatically operated to facilitate fluid handling by such devices. The occlusion assemblies may be designed to position and immobilized the tubing and may include a frame or other support feature providing tubing guides and/or configured for attachment to or integration with a fluid handling assembly of a device of which they are part or with which they are used. The occlusion assemblies comprise a tubing occluder, which may be a mechanism constructed and positioned to apply a force to the tube(s) associated with the occlusion assembly to occlude the tubes and to release the force to allow the tubes to open for fluid flow. The occlusion assemblies and tubing occluders may be configured to include a single tube in certain cases, and in other cases to occlude multiple tubes, whether an odd number of tubes or an even number of tubes. Certain occlusion assemblies are specifically configured for occluding one or more pairs of tubes and may include tubing occluders having a separate occluding member for occluding each of the pair of collapsible tubes. The occlusion assemblies may include automatic actuators for operating the tubing occluders, and in certain cases also include a manual actuator to provide an override function. The occlusion assemblies may include a door designed and positioned to cover at least a portion of the tubes be included and tubing occluder mechanism.
