Abstract
The invention relates to an apparatus for the treatment of a medical liquid comprising a liquid treatment machine and a cassette insertable therein substantially made of a rigid base body of the cassette with fitted chambers and passages and a foil covering them.
Claims23
A set of medical fluid cassettes, comprising:
- a first cassette having a base body with a first chamber and passages, and a foil that covers the first chamber and passages;
- and
- a second cassette having a base body with first and second chambers and passages, and a foil that covers the first and second chambers and passages,
- wherein the first chamber of the first cassette is positioned to correspond to the first chamber of the second cassette, the second chamber of the second cassette is positioned to correspond to a region of the first cassette that does not include a chamber, the first chamber of the first cassette is positioned to align with a first actuator of a liquid treatment machine when the first cassette is disposed within a cassette compartment of the liquid treatment machine, the first chamber of the second cassette is positioned to align with the first actuator of the liquid treatment machine when the second cassette is disposed within the cassette compartment of the liquid treatment machine, the region of the first cassette that does not include a chamber is positioned to align with a second actuator of the liquid treatment machine when the first cassette is disposed within the cassette compartment of the liquid treatment machine, and the second chamber of the second cassette is positioned to align with the second actuator of the liquid treatment machine when the second cassette is disposed within the cassette compartment of the liquid treatment machine.

A set of medical fluid cassettes, comprising:
- a first medical fluid cassette forming a plurality of fluid channels and chambers, the plurality of fluid channels and chambers of the first medical fluid cassette being configured so that the first medical fluid cassette can be used with a medical treatment machine to provide a first type of medical treatment;
- a second medical fluid cassette forming a plurality of fluid channels and chambers, the plurality of fluid channels and chambers of the second medical fluid cassette being configured so that the second medical fluid cassette can be used with the medical treatment machine to provide a second type of medical treatment,
- 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 first type of medical treatment is different than the second type of medical treatment.
15-109. (canceled)
A medical system, comprising:
- a medical treatment machine defining a cassette compartment;
- and
- a set of medical fluid cassettes, comprising
- a first medical fluid cassette configured to be disposed within the cassette compartment of the medical treatment machine, the first medical fluid cassette forming 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 medical treatment machine is operated;
- and
- a second medical fluid cassette configured to be disposed within the cassette compartment of the medical treatment machine, the second medical fluid cassette forming a plurality of fluid channels and chambers, the medical system being configured to provide a second type of medical treatment when the second medical fluid cassette is disposed within the cassette compartment and the medical treatment machine is operated,
- 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 first type of medical treatment is different than the second type of medical treatment.
