The specification discloses a portable dialysis machine having a detachable controller unit and base unit. 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 planar surface for receiving a container of fluid, a scale integrated with the planar surface, a heater in thermal communication with the planar surface, and a sodium sensor in electromagnetic communication with the planar surface. Embodiments of the disclosed portable dialysis system have improved structural and functional features, including improved modularity, ease of use, and safety features.

It is described an extracorporeal blood treatment apparatus (1) with a user interface (12) device capable configuring and allowing execution of one or more isolated ultrafiltration tasks during the course of a dialysis treatment. The extracorporeal blood treatment apparatus (1) is controlled in a normal mode, where dialysis fluid is fed to the blood treatment unit (2), and in an isolated ultrafiltration mode, where fresh dialysis fluid is no longer fed to the blood treatment unit (2).

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 based on a fluid flow rate set by the operator and on a prescribed dose value (D.sub.set).

A dialysis machine has a blood circuit, a blood pump, a dialyzer, a venous pressure sensor, a substituate line, and a control unit. The control unit can operate the blood pump in a first operating mode and in a special operating mode, and start the special operating mode after a trigger event. In the special operating mode, a blood pump conveying rate is controlled via a default value or regulated to a desired value, with the default or desired value being derived from a value determined before the started special mode or corresponding to the value. The presence of an obstacle is polled before the special mode, and depending on the presence thereof, the start of the special mode is blocked or delayed and/or the selection of the default value or the desired value on the presence of the obstacle differs from the selection without the presence of the obstacle.

A blood sampling transfer device that includes a lancing tape having a flow channel and a transfer cartridge removably connected to the lancing tape is disclosed. The blood sampling transfer device provides a closed system that reduces the exposure of a blood sample to both skin and environment and provides fast mixing of a blood sample with a sample stabilizer.

Apparatus and method for photo-chemical oxidation are disclosed herein. In one embodiment, a dialysis fluid regeneration system includes: a nanostructured anode; a source of light configured to illuminate the anode; and a cathode that is oxygen permeable.

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 based on a fluid flow rate set by the operator and on a prescribed dose value (D.sub.set).

A blood based solute monitoring system for measuring at least one blood solute species that has a first recirculation flow path in communication with a dialyzer. The first recirculation flow path is configured to allow a fluid to recirculate through a dialyzer such that the concentration of at least one solute species in the fluid becomes equilibrated to the solute species concentration of the blood compartment of the dialyzer. The blood solute monitoring system has at least one sensor to measure a fluid characteristic.

A computer-implemented method for controlling fluid flow rates during a biological fluid procedure, comprising providing a membrane separator configured to separate a biological fluid into filtrate and retentate, wherein concentration of retentate exiting the membrane separator is controllable by altering a flow rate of the retentate exiting the membrane separator. The computer-implemented method also comprises detecting a change of attenuated retentate particles within the filtrate, comparing the change of attenuated retentate particles within the filtrate with a threshold level, and providing a response action comprising altering the concentration of retentate exiting the membrane separator if the change of attenuated retentate particles within the filtrate exceeds the threshold level.

The disclosure relates to a blood treatment device for use in blood treatment therapies, comprising: an extracorporeal blood circuit, a dialyzer and a dialysis fluid circuit, wherein the extracorporeal blood circuit and the dialysis fluid circuit are separated from each other via a membrane provided in the dialyzer, via which blood can be filtered; at least one substitution solution pump, which is configured to supply a substitution solution to the extracorporeal blood circuit before and/or after the dialyzer; an effluent pressure sensor, which is configured to measure a pressure in the dialysis fluid circuit after the dialyzer, and a control unit, which is configured to automatically reduce a flow rate of the at least one substitution solution pump when an effluent pressure measured by the effluent pressure sensor drops during an ongoing blood treatment therapy.
