An apparatus for extracorporeal treatment of fluid and a process of setting up a medical apparatus for the delivery or collection of fluids are disclosed. According to the apparatus and the process, a control unit (10) is configured calculate set values of two or more of the fluid flow rates by imposing that an emptying time of containers of fresh fluid (16, 20, 21, 26) and/or a filling time of a waste container is substantially same as, or multiple of, the emptying time of one or more of the other containers of fresh fluid.

The specification discloses a portable dialysis machine having a detachable controller unit and base unit with an improved reservoir heating system. The controller unit includes a door having an interior face, a housing with a panel, where the housing and panel define a recessed region configured to receive the interior face of the door, and a manifold receiver fixedly attached to the panel. The base unit has a reservoir with an internal pan and external pan, separated by a space that holds a heating element. The heating element is electrically coupled to electrical contacts attached to the external surface of the external pan.

A blood purification apparatus that includes a blood circuit including an arterial blood circuit and a venous blood circuit and through which blood of a patient is allowed to extracorporeally circulate; a blood purification unit connected to and provided between the arterial blood circuit and the venous blood circuit and that purifies the blood flowing through the blood circuit; a blood pump provided to the arterial blood circuit and that delivers the blood of the patient from a distal end of the arterial blood circuit to a distal end of the venous blood circuit; a substitution line through which a substitution fluid is allowed to be introduced into the blood circuit; and an infusion portion attached to the substitution line and from which a predetermined liquid drug to be administered to the patient is allowed to be infused into the substitution line. The blood purification apparatus includes a control unit that executes a drug introduction mode in which the substitution fluid in the substitution line is introduced into the blood circuit, the control unit causing the liquid drug infused from the infusion portion in the drug introduction mode to be introduced into the blood circuit together with the substitution fluid; and a calculation unit that calculates a volume of the substitution fluid introduced from the substitution line into the blood circuit with the execution of the drug introduction mode.

A blood purification device includes a blood circuit for extracorporeally circulating blood of a patient; a liquid supply line for supplying a supply liquid to a blood purifier provided on the blood circuit or to the blood circuit a peristaltic liquid supply pump provided on the blood circuit or on the liquid supply line; a peristaltic waste liquid pump provided on a waste liquid line through which a waste liquid is discharged from the blood purifier; a water balance amount detection unit for detecting a water balance amount of the supply liquid and the waste liquid; and a water balance amount control unit that corrects one or both of pump speeds of the liquid supply pump and the waste liquid pump so that the water balance amount detected by the water balance amount detection unit matches a target water balance amount. The water balance amount control unit is configured to be able to switch between a first correction condition for correcting the pump speed on every water balance amount detection and a second correction condition for correcting the pump speed based on a plurality of water balance amount detection results.
