An automated peritoneal dialysis system and machine configured to perform dextrose mixing are disclosed. An example dialysis machine includes a pump, a first solution having a first formulation stored in a first container that is placed in fluid communication with the pump, and a second solution having a second formulation stored in a second container that is also placed in fluid communication with the pump. The first container has a first unique identifier indicative of the first formulation and the second container has a second unique identifier indicative of the second formulation. The dialysis machine also includes a logic implementer programmed to receive a therapy prescription and operate the pump if the first formulation indicated by the first unique identifier is specified by the therapy prescription, or the second formulation indicated by the second unique identifier is specified by the therapy prescription.

An apparatus for treating a medical fluid is provided which includes a treatment machine having a coupling surface, with a cassette made of a hard part having liquid-conducting passages which are covered by a flexible film being able to be coupled to the coupling surface of the treatment machine. A corresponding medical cassette is also provided. An air-free coupling of the flexible film of the cassette to the treatment machine is ensured in that air can be sucked out areally along a plane between the flexible film and the coupling surface during the coupling process and/or with a coupled cassette. A method for coupling the cassette and a method for checking the leaktightness of the cassette via the vacuum control of the air suction is also provided.

A system for performing a dialysis treatment includes a dialysis fluid machine; a disposable dialysis fluid carrying member operable with the dialysis fluid machine; and a venting filter provided by the disposable member, the venting filter positioned and arranged to be coupled along with the disposable member to the dialysis fluid machine to perform the dialysis treatment and to vent air from the disposable member.

A medical infusion fluid handling system, such as an automated peritoneal dialysis system, may be arranged to de-cap and connect one or more lines (such as solution lines) with one or more spikes or other connection ports on a fluid handling cassette. This feature may reduce a likelihood of contamination since no human interaction is required to de-cap and connect the one or more lines and the one or more spikes. For example, the automated peritoneal dialysis system may include a carriage arranged to receive the one or more lines each having a connector end and a cap. The carriage may move along a first direction so as to move the connector ends of the one or more lines along the first direction, and a cap stripper may be arranged to engage with the caps on the solution lines on the carriage. The cap stripper may move in a second direction transverse to the first direction, as well as to move with the carriage along the first direction.

The availability of a heart-lung machine in a box provides an opportunity for saving lives in emergency situations arising outside a hospital and for more cost effective care in hospital settings.

An automated peritoneal dialysis system and machine configured to perform dextrose mixing are disclosed. An example dialysis machine includes at least one pump, a first dialysate having a first dextrose level placed in fluid communication with the at least one pump, and a second dialysate having a second dextrose level placed in fluid communication with the at least one pump. The example dialysis machine also includes first and second valves placed between the first and second dialysates and the at least one pump. The example dialysis machine further includes a logic implementer programmed to operate the at least one pump and the first and second valves to mix the first and second dialysates so as to form a third dextrose level.

A method is provided for detecting leaks in a disposable medical fluid cassette that includes a base and a flexible membrane attached to the base in such a way that the base and the flexible membrane cooperate to at least partially form a fluid passageway. The method includes applying a first force to the flexible membrane, measuring a first physical property of a system that includes the medical fluid cassette a medical fluid pumping machine, removing the first force from the flexible membrane, applying a second force to the flexible membrane, measuring a second physical property of the system, and determining whether the medical fluid cassette leaks based on a comparison of the first physical property and the second physical property.

A dialysis fluid system includes a dialysis fluid inlet; a dialysis fluid outlet; a pump positioned and arranged to pump dialysis fluid through the dialysis fluid inlet and the dialysis fluid outlet; and an inductive heater located between the dialysis fluid inlet and the dialysis fluid outlet, the inductive heater including a fluid flowpath positioned and arranged to receive non-heated dialysis fluid from the dialysis fluid inlet and to output heated dialysis fluid to the a dialysis fluid outlet, a conductive heater element located within the fluid flowpath so as to be or act as a secondary coil of a transformer, and a primary coil of the transformer located outside of the fluid flowpath and positioned so as to magnetically induce a current into the conductive heater element, causing the conductive heater element and surrounding fluid to heat.

A medical fluid delivery system comprises: (i) a medical fluid delivery machine including a pneumatic manifold having pump and valve actuation areas and a pumping gasket overlaying the pump and valve actuation areas, sources of positive and negative pneumatic pressure, plural pneumatic valves located between the pneumatic sources and the pump and valve actuation areas, and a control unit in operable communication with the plural pneumatic valves; and (ii) a disposable cassette including a fluid pump chamber that aligns with the pump actuation area when the disposable cassette is mated with the pneumatic manifold, the disposable cassette including sheeting overlaying the fluid pump chamber, wherein the control unit is configured to operate the pneumatic valves to perform a conditioning routine that moves the pumping gasket and the cassette sheeting while mated in an attempt to remove small air pockets from between the pumping gasket and the cassette sheeting.

A dialysis system includes a disposable cassette including a flexible sheet and a plurality of dialysis fluid pathways, a plurality of actuators operable with the flexible sheet to direct dialysis fluid through the plurality of dialysis fluid pathways, and a controller configured to (i) determine at least one limitation of the plurality of dialysis fluid pathways, (ii) generate a flow schedule indicating how dialysis fluid should be directed through the plurality of dialysis fluid pathways in accordance with the at least one limitation, and (iii) control the plurality of actuators so that dialysis fluid is pumped through the plurality of dialysis fluid pathways according to the flow schedule.
