Abstract
A dialysis system includes: (i) a source of water made suitable for a dialysis treatment; (ii) at least one concentrate for mixing with the water from the source; (iii) a dialysis fluid pump; and (iv) a disposable set operable with the dialysis fluid pump and in fluid communication with the source of water and the at least one concentrate, the disposable set including a container having a first end and a second end, the container configured to allow the water and the at least one concentrate pumped by the dialysis fluid pump to enter at the second end and exit from the first end to mix for the dialysis treatment.
Claims28
A dialysis system comprising:
- a source of water made suitable for a dialysis treatment;
- at least one concentrate for mixing with the water from the source;
- a dialysis fluid pump;
- and
- a disposable set operable with the dialysis fluid pump and in fluid communication with the source of water and the at least one concentrate, the disposable set including a container having a first proximal end and a second distal end, the container configured such that the water and the at least one concentrate pumped by the dialysis fluid pump enters at the second distal end and exits from the first proximal end, via a passageway extending from the first proximal end to the second distal end, to mix for the dialysis treatment,
- wherein the first proximal end includes a connector, the connector defining at least one groove positioned and arranged on an outer surface of the connector,
- the at least one groove is configured to allow the water and the at least one concentrate, which are at least partially mixed together, to travel through the at least one groove formed between the connector and the container to a port of the container, and
- the connector is associated with at least one one-way valve configured to prevent the water and the at least one concentrate from flowing from an inside of the container and back through the passageway towards the first proximal end.

A dialysis system comprising:
- a source of water made suitable for a dialysis treatment;
- at least one concentrate for mixing with the water from the source;
- and
- a disposable set in fluid communication with the source of water and the at least one concentrate, the disposable set including a container having a first proximal end and a second distal end, the container including (i) a tube structured and arranged within the container, the tube extending from the first proximal end to the second distal end such that the water and the at least one concentrate to flow through the tube and enter the container at the second distal end and (ii) a port at the first proximal end, the port associated with at least one one-way valve such that the water and the at least one concentrate at least partially mixed for the dialysis treatment exit the first proximal end of container while the at least one one-way valve prevents the water and the at least one concentrate from traveling back through the tube towards the first proximal end, wherein the first proximal end of the container includes a connector, the port forming part of the connector, and wherein the connector is placed in fluid communication with the tube.

A dialysis system comprising:
- a source of water made suitable for a dialysis treatment;
- at least one concentrate for mixing with the water from the source;
- and
- a disposable set in fluid communication with the source of water and the at least one concentrate, the disposable set including a container having at least one outer seal forming a first proximal end and a second distal end, the container sealed within the at least one outer seal so as to form a passageway leading to the second distal end of the container, the container further including a port at the first proximal end, the port associated with at least one one-way valve, wherein
- the passageway is structured and arranged such that the water and the at least one concentrate enter the passageway, from the port at the first proximal end, and flow, according to the at least one one-way valve, through the passageway to enter the container at the second distal end, and
- the port is structured and arranged such that the water and the at least one concentrate that have at least partially mixed for the dialysis treatment to exit the first proximal end of the container while the at least one one-way valve prevents the water and the at least one concentrate from traveling back through the passageway.
