Abstract:
1. A dialysis fluid cassette comprising: a rigid body having a first recessed portion; and a flexible backing covering the first recessed portion, the flexible backing cooperating with the first recessed portion of the rigid body to at least partially form a gas release chamber that has a liquid inlet port, a liquid outlet port, and a gas outlet port, wherein the gas release chamber is configured such that, when the dialysis fluid cassette is disposed within a cassette compartment of an associated dialysis machine, the gas outlet port is positioned near a top region of the gas release chamber and the liquid inlet and outlet ports are positioned near a bottom region of the gas release chamber; wherein the gas release chamber has a height sufficient to allow a first liquid in the top region of the gas release chamber to remain substantially stagnant as a portion of a second liquid in the bottom region of the gas release chamber flows through the gas release chamber from the region of the gas release chamber and the second liquid in the bottom region of the gas release chamber is maintained as the portion of the second liquid flows through the gas release chamber from the liquid inlet port to the liquid outlet port, and the first and second liquids are miscible liquids.
