Abstract: 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.

Abstract: A holder attachable to a person's belt supports an open drink container in an upright condition so that the container can be removed to consume its contents. In a preferred embodiment, the container is a wide-mouthed container with a removable lid and the holder has an upper retaining portion for reception of the container in a downward direction to a preselected operative position. A lower stop portion carried with the retaining portion engages the bottom of the container in the operative position thereof to support the weight of the container. An intermediate portion can also be provided between the retaining portion and the stop portion to press inwardly against the container and stabilize it against substantially lateral forces.
