Dialysis systems and methods for operating dialysis machines (e.g., peritoneal dialysis machines) for conducting dialysis treatments are disclosed. The dialysis system may include a dialysis machine for transferring dialysate to a patient from a dialysate bag. The dialysate may flow from the dialysate bag through a disposable cartridge or cassette positionable within the dialysis machine. A filter may be included in, coupled to, etc., the dialysis machine. In use, the filter may be configured to filter out air content from the dialysate. In some embodiments, the filter may be incorporated into and/or operatively coupled to the disposable cartridge or cassette inserted into the dialysis machine.

Embodiments of the present disclosure include a dialysis system having a disposable cartridge which includes one or more flowpaths arranged on or within the cartridge, where the one or more flowpaths including at least one of a blood flowpath for carrying a volume of blood to be treated in a dialyser and a dialysate flowpath, isolated from the blood flowpath, for delivering a flow of dialysate solution through the dialyser.

Systems and methods for cleaning and disinfecting a medical therapy device that delivers any one of hemodialysis, hemodiafiltration and hemofiltration. The system has a base module that has at least one segment of a controlled compliant flow path and at least one pair of jumpered ports configured on the base module. One or more components have connections connectable to the jumpered ports of the base module to provide for fluid communication between the segment of the controlled compliant flow path in the base module and a flow path defined by the one or more components. The base module is connected to the one or more components that define a flow path configurable for carrying out in part at least one function performed during any one of hemodialysis, hemodiafiltration or hemofiltration.

A portable hemodialysis system is provided including a disposable cartridge and a reused dialysis machine. The disposable cartridge includes a dialyzer, and a dialysate flow path and a blood flow path which flow in opposing directions through the dialyzer. The disposable cartridge includes pressure and fluid flow sensors for measuring the pressure and fluid flow in the dialysate flow path and blood flow path. In addition, the disposable cartridge possesses pump actuators (but not pump motors) for pumping dialysate and blood through their respective flow paths. Preferably, the disposable cartridge includes a filter for removing waste products from dialysate.

A portable dialysis cabinet for use in dialysis. The portable dialysis cabinet can have a size and weight that facilitates easy movement of the cabinet from one location to another with relative ease. The portable dialysis cabinet can have additional features necessary to facilitate portability, such as wheels and a handle. In general, the portable dialysis cabinet can contain all the necessary components for performing a dialysis session.

The hemodialysis system includes a closed loop dialysate flow path which includes a dialyzer and a reservoir for storing dialysate, and a closed loop blood flow path which passes through the dialyzer in the opposite direction as the dialysate flow path. In addition, the hemodialysis system includes pumps for pumping dialysate and blood through their respective flow paths, a flow sensor for measuring the flow rate of dialysate in the dialysate flow path, and a level sensor for measuring the level of dialysate in the dialysate reservoir. A processor is connected to the flow sensor, reservoir level sensor and pumps to provide a first closed loop control system including the processor, flow sensor and a first dialysate pump, and a second closed loop control system including the processor, level sensor and a second dialysate pump which enable the processor to initiate, monitor and maintain ultrafiltration.

Systems and methods for controlling fluid movement and volumes of fluid between a subject and a controlled compliant flow path. The controlled compliant flow path has a means for selectively metering in and metering out fluid from the controlled compliant flow path. An extracorporeal flow path is in fluid communication with the controlled compliant flow path across a semi-permeable membrane where the extracorporeal flow path has a first terminal end and a second terminal end.

A system and method for balancing flows of renal replacement fluid is disclosed. The method uses pressure controls and pressure sensing devices to more precisely meter and balance the flow of fresh dialysate and spent dialysate. The balancing system may use one or two balancing devices, such as a balance tube, a tortuous path, or a balance chamber.

A blood purification device includes a device body and a cassette. The cassette includes: a casing that accommodates a removal water receptacle; and pump tube. The device body includes fingers, a driving unit, and a housing. The cassette can be attached to and removed from the housing of the device body so that the pump tubes are positioned between the plurality of fingers and the outer surfaces of the casing.
