摘要： An occlusion assembly for compressing a pair of collapsible tubes comprises a frame comprising a tubing guide configured for positioning the collapsible tube. The occlusion assembly also comprises a tubing occluder mounted to the frame with an occluding member constructed and positioned to controllably occlude or release occlusion of the collapsible tube. A door mounted to the frame is positioned to cover at least a portion of the collapsible tube and tubing occluder when closed and provide user access when open. The assembly includes a retainer mechanism engaged by the door when the door is closed to permit operation of the tubing occluder when the door is closed and retain the tubing occluder in a non-occluding configuration when the door is opened.

摘要： A drain cassette for a dialysis unit has a fluid channel between venous and arterial connection ports, and a valve may controllably open and close fluid communication between a drain outlet port and the venous connection port or the arterial connection port. A blood circuit assembly and drain cassette may be removable from the dialysis unit, e.g., by hand and without the use of tools. A blood circuit assembly may include a single, unitary member that defines portions of a pair of blood pumps, control valves, channels to accurately position flexible tubing for an occluder, an air trap support, and/or other portions of the assembly. A blood circuit assembly engagement device may assist with retaining a blood circuit assembly on the dialysis unit, and/or with removal of the assembly. An actuator may operate a retainer element and an ejector element that interact with the assembly.

摘要： An occlusion assembly for compressing a pair of collapsible tubes comprises an occluding member for each tube. Each occluding member is forced into an occluding position by a spreader positioned within a space between the occluding members that slides along a side of each occluding member causing a tube-contacting portion of each occluding member to compress the collapsible tubes. A main spring may be included that urges the spreader toward the distal ends of the occluding members and into an occluding position. The spreader may be moved against the biasing force of the main spring into a non-occluding position near the proximal ends of the occluding members either manually through a button and linkage assembly coupled to the spreader, or by an automatic actuator coupled to the spreading element.

摘要： 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. Such occlusion assemblies may include safety features, for example, to prevent a release of occlusion force on the tubing when the door is not in a closed position and/or convenience features, for example a retainer mechanism to hold the tube occluder in a non-occluding position when the door is open with the tube occluder in the non-occluding position.
