Abstract
A dialysis fluid pressure manifold system includes a plurality of pump and valve chambers controlling a flow of dialysis fluid; a header including a plurality of pneumatic passageways, each passageway in pneumatic communication with one of the pump or valve chambers; a plurality of electrically actuated pneumatic valves; and a plate defining a plurality of pneumatic apertures, each pneumatic aperture in pneumatic communication with one of the plurality of electrically actuated pneumatic valves, the plate providing the apertures each with an o-ring seal for airtight connection with the pneumatic passageways of the header.
Claims18
A dialysis fluid pressure manifold system comprising:
