A patient fluid removal compensation volume may be determined to make up for the patient fluid removal that does not occur during machine down times, and the patient fluid removal rate may be increased until the compensating volume is satisfied.

The present specification describes a modular, portable hemofiltration system, for providing improved clearance levels of blood toxins, which includes at least one roller pump that is designed and operated to generate a rapidly varying pressure profile of fluid within at least a blood circuit of the hemofiltration system.

Dialysis systems comprising actuators that cooperate to perform dialysis functions and sensors that cooperate to monitor dialysis functions are disclosed. According to one aspect, such a hemodialysis system comprises a user interface model layer, a therapy layer, below the user interface model layer, and a machine layer below the therapy layer. The user interface model layer is configured to manage the state of a graphical user interface and receive inputs from a graphical user interface. The therapy layer is configured to run state machines that generate therapy commands based at least in part on the inputs from the graphical user interface. The machine layer is configured to provide commands for the actuators based on the therapy commands

The present invention provides an extracorporeal dialysis apparatus which allows the automation of some operations in order to make possible a safe home treatment or to facilitate the treatment process for example the priming and/or the blood return process. Thus, the object is to automatically perform a series of processes from hemodialysis preparation to treatment completion safely, reliably and speedily, and to significantly reduce the labor and supply costs.

An apparatus for ultrafiltration of a patient being overhydrated due to congestive heart failure, comprising a tube set including a connector (21) for connection to a patient line (3) for access to the peritoneal cavity of the patient. A flow pump (41-43) is arranged for addition and removal outflow and inflow (recirculation) of fluid from/to the peritoneal cavity. An osmotic agent peristaltic pump (16) is arranged for replenishment of glucose solution to the fluid added to the peritoneal cavity for promoting ultrafiltration. The glucose is replenished intermittently for keeping a concentration of glucose substantially constant in the peritoneal cavity. The flow pump comprises a pressure chamber (43) with rigid walls and a flexible pump bag (41) arranged therein. An air pump (45) pressurizes the chamber for outflow of fluid from the peritoneal cavity by a sub pressure and inflow of fluid to the peritoneal cavity by an overpressure, which pressures are maintained within safe limits.

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 present invention provides a hemodialysis machine comprising a removably mountable cartridge having at least one inlet and at least one outlet, the cartridge defining a fluid pathway between said at least one inlet and said at least one outlet, a sanitisation device having an inlet and an outlet, a conduit connected between an outlet of the cartridge and the inlet of the sanitisation device and, a conduit connected between the outlet of the sanitisation device and an inlet of the cartridge.
