In medical apparatus, for example a dialysis machine, a pump in conjunction with a multichambered reservoir is provided. The volume pumped is determined by counting the number of fills of the reservoir made during a pumping phase. A less expensive pump may be used whilst maintaining an accurate determination of the volume pumped.

Described are embodiments that include methods and devices for separating components from multi-component fluids. Embodiments may involve use of separation vessels and movement of components into and out of separation vessels through ports. Embodiments may involve the separation of plasma from whole blood. Also described are embodiments that include methods and devices for positioning portions, e.g., loops, of disposables in medical devices. Embodiments may involve use of surfaces for automatically guiding loops to position them into a predetermined position.

Implementations of a delivery device and method are disclosed. One implementation is a delivery device comprising a flow chamber with an inlet port for receiving a fluid flow in the flow chamber, and an outlet port for exiting a material from the flow chamber. The flow chamber may include a formation portion in which a suspension of the material is formed, and a collection portion that directs the suspension toward and/or into the outlet port. An amount of the material may collect in the collection portion adjacent the outlet port. The device may further comprise an insertion port for permitting insertion of the material in the flow chamber, and/or a pusher operable to move the amount of material through the outlet port. Related devices and methods also are disclosed.

A lid for closing an open ended blood chamber is provided. The lid is a one piece device forming an inlet to the blood chamber. The one piece device includes a filter media spaced apart from the inlet and wherein blood passing through the inlet passes through the filter media upon entry into the blood chamber. The filter media filters gross particulate from the blood passing therethrough. The one piece device further includes a vent port with an associated vent port cover to allow air separated to vent from the blood chamber.

A system for the extracorporeal elimination of carbon monoxide, includes at least one pump and a gas exchange chamber, wherein the at least one pump can be connected to the blood circulatory system of a person by way of a first tube section connectable to a cannula and is connected to a gas exchange chamber via a second tube section, wherein the system is configured to transfer blood, via the first tube section, from the blood circulatory system of the person by way of at least one pump into the gas exchange chamber, and to return the blood from the gas exchange chamber to the blood circulatory system of the person via the same first tube section.
