1. A medical fluid cartridge comprising:
- a body comprising;
a first portion defining a meandering fluid passageway extending between a fluid inlet port and a fluid outlet port, anda second portion defining a fluid passageway extending between the fluid inlet port and the fluid outlet port, anda partition arranged so that a cross sectional area of the meandering passageway adjacent the fluid inlet port is less than a cross sectional area of the fluid passageway defined by the second portion adjacent the fluid inlet port;
wherein the partition is configured such that a first flow path of the meandering passageway adjacent the fluid inlet port is substantially parallel to a second flow path of the fluid passageway adjacent the fluid inlet port,wherein the partition is positioned adjacent to the fluid inlet port such that when fluid flows into the medical fluid cartridge via the fluid inlet port, the fluid is divided between the meandering fluid passageway and the fluid passageway defined by the second portion; and
wherein the meandering fluid passageway and the fluid passageway defined by the second portion are configured so that when fluid flows into the medical fluid cartridge via the fluid inlet port, a flow rate of fluid flowing through the meandering fluid passageway is less than a flow rate of fluid flowing through the fluid passageway defined by the second portion.

10. A medical fluid system comprising:
-
a medical fluid pumping machine; a magnet assembly defining a cavity, the magnet assembly being configured to generate a magnetic field within the cavity; and a medical fluid cartridge comprising; a body comprising; a first portion defining a meandering fluid passageway extending between a fluid inlet port and a fluid outlet port, and a second portion defining a fluid passageway extending between the fluid inlet port and the fluid outlet port, and a partition arranged so that a cross sectional area of the meandering passageway adjacent the fluid inlet port is less than a cross sectional area of the fluid passageway defined by the second portion adjacent the fluid inlet port; wherein the partition is positioned adjacent to the fluid inlet port such that when fluid flows into the medical fluid cartridge via the fluid inlet port, the fluid is divided between the meandering fluid passageway and the fluid passageway defined by the second portion; wherein the meandering fluid passageway and the fluid passageway defined by the second portion are configured so that when fluid flows into the medical fluid cartridge via the fluid inlet port, a flow rate of fluid flowing through the meandering fluid passageway is less than a flow rate of fluid flowing through the fluid passageway defined by the second portion. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
