Abstract

A dialysis system includes a dialysis instrument including at least one pump actuator; a disposable cassette operable with the at least one pump actuator; a plurality of supply containers connected fluidly to the disposable cassette; and a cart which includes a rotatable bearing plate onto which the instrument and supply containers are loaded, the bearing plate allowing a patient to turn the instrument and supply containers relative to the cart for selective access to the instrument or the supply containers.

Claims

1. A dialysis system comprising:

a dialysis instrument including at least one pump actuator;

a disposable cassette operable with the at least one pump actuator, the disposable cassette including a first originating supply line and a second originating supply line, each of the first and second originating supply lines extending from the disposable cassette to a first set of branching supply lines and to a second set of branching supply lines;

a plurality of supply containers, each supply container including a solution line connectable to one of the supply lines of the first set of branching supply lines or one of the supply lines of the second set of branching supply lines; and

a device configured to recognize whether a line interfacing with the instrument is one of the solution lines from one of the supply containers or a line from one of the first and second sets of branching supply lines.

2. The dialysis system of claim 1, wherein the first and second sets of branching supply lines each include at least four branching supply lines.

3. The dialysis system of claim 2, which includes a clamp on each originating supply line.

4. The dialysis system of claim 1, wherein the device is configured to recognize whether a line interfacing with the instrument is one of a single bag solution, a multiple chamber bag solution, and a multiple bag solution that requires mixing.

5. The dialysis system of claim 1, wherein the plurality of supply containers are first supply containers and the solution lines are first solution lines, and which includes a plurality of second supply containers, each second supply container including a second solution line connectable to one of the supply lines of the first set of branching supply lines or one of the supply lines of the second set of branching supply lines, and an autoconnection mechanism configured to (i) disconnect the first set of branching supply lines from the first solution lines, and (ii) connect the second set of branching supply lines to the second solution lines.

6. A dialysis system comprising:

a dialysis instrument including at least one pump actuator;

a disposable cassette operable with the at least one pump actuator, the disposable cassette including a first originating supply line and a second originating supply line, each of the first and second originating supply lines extending from the disposable cassette to a first set of branching supply lines or to a second set of branching supply lines;

a plurality of first supply containers, each first supply container including a first solution line connectable to one of the supply lines of the first set of branching supply lines or one of the supply lines of the second set of branching supply lines;

a plurality of second supply containers, each second supply container including a second solution line connectable to one of the supply lines of the first set of branching supply lines or one of the supply lines of the second set of branching supply lines; and

an autoconnection mechanism configured to (i) disconnect the first set of branching supply lines from the first solution lines, and (ii) connect the second set of branching supply lines to the second solution lines.
