1. A medical system, comprising:
- a medical treatment machine defining a cassette compartment, the medical treatment machine comprising a plurality of piston pump members and valve members; and
a set of medical fluid cassettes, comprisinga first medical fluid cassette configured to be disposed within the cassette compartment of the medical treatment machine, the first medical fluid cassette comprising a cover foil attached to a base body, the cover foil and the base body cooperating to at least partially form a plurality of fluid channels and chambers, the medical system being configured to provide a first type of medical treatment when the first medical fluid cassette is disposed within the cassette compartment and the plurality of piston pump members and valve members of the medical treatment machine are operated in a first manner, at least one of the valve members of the medical treatment machine being aligned with a portion of the first medical fluid cassette that does not comprise a fluid channel or a chamber when the first medical fluid cassette is disposed within the cassette compartment; and
a second medical fluid cassette configured to be disposed within the cassette compartment of the medical treatment machine, the second medical fluid cassette comprising a cover foil attached to a base body, the cover foil and the base body cooperating to at least partially form a plurality of fluid channels and chambers, the medical system being configured to provide a second type of medical treatment that is different than the first type of medical treatment when the second medical fluid cassette is disposed within the cassette compartment and the plurality of piston pump members and valve members of the medical treatment machine are operated in a second manner that differs from the first manner,wherein the configuration of the plurality of fluid channels and chambers of the first medical fluid cassette is different than the configuration of the plurality of fluid channels and chambers of the second medical fluid cassette, and the medical treatment machine has the same structural configuration when operated with the first medical fluid cassette to provide the first type of medical treatment as when operated with the second medical fluid cassette to provide the second type of medical treatment.
