Abstract:
1. A dialysis system, comprising: a dialysis machine having a cassette compartment configured to receive a dialysis fluid cassette that comprises a fluid channel formed between a base and a flexible membrane that is attached to the base, the cassette compartment being configured such that the membrane of the dialysis fluid cassette is positioned adjacent a machine block of the dialysis machine when the dialysis fluid cassette is disposed in the cassette compartment of the dialysis machine; a valve member at least partially disposed in a recess defined by the machine block, the valve member being substantially aligned with a portion of the fluid channel of the dialysis fluid cassette when the dialysis fluid cassette is disposed in the cassette compartment of the dialysis machine, the valve member comprising a sealing cap that seals off a pressure passage in communication with the valve member, the sealing cap forming a deformable area configured to deform outwardly when pressurized fluid is introduced into the sealing cap of the valve member via the pressure passage, wherein the valve member is configured so that the deformable area contacts the membrane of the dialysis fluid cassette and obstructs the fluid channel of the dialysis fluid cassette to control dialysis fluid flow through the dialysis fluid cassette when the dialysis fluid cassette is disposed in the cassette compartment of the dialysis machine and the deformable area is outwardly deformed by introducing pressurized fluid into the sealing cap of the valve member.
