Abstract: A blood treatment device includes an extracorporeal blood circuit, a dialyzer and a dialysis fluid circuit. The extracorporeal blood circuit has an arterial portion, a venous portion, an air detector configured to monitor whether air is present in the venous portion, at least one blood pump configured to pump blood through the extracorporeal blood circuit, a venous hose clamp configured to selectively clamp or release the venous portion, a user interface, and a control unit. When the control unit receives information from the air detector that there is air in the venous portion, the control unit is configured to stop the blood pump, close the venous hose clamp, raise an alarm, and display on the user interface instructions for removing air in the venous portion and displaying status reports about the removal of air, and carry out automatic removal of air from the venous portion on a user-initiated basis.

Abstract: A light shield is arranged in a light shielding position with respect to a sensor or a blood leakage detector installed in a medical apparatus and monitoring for changes of transmittance in a translucent fluid carried in a tubing connected to the medical apparatus. The light shield has a non-transparent configuration and is configured to prevent environmental light from being incident on a relevant detection active sensor area. Further, a disposable kit for a medical apparatus which is arranged to be mounted to the medical apparatus and to carry pre-installed disposables to be used during a medical treatment comprises a hard-shell subassembly arranged to be positioned in a region of the medical apparatus in the vicinity of a detection active sensor area of a sensor which is sensitive to light and installed in the medical apparatus.

Abstract: An attachment assembly for attaching a fluid container to a fluid warmer of a system for extracorporeal blood treatment is disclosed. The assembly includes a hook-shaped fixture located on the fluid warmer, a pin-shaped fixture located on the fluid warmer, and receiving members located on the fluid container to receive the hook-shaped fixture and the pin shaped fixture located on the fluid warmer. A fluid warmer containing a hook-shaped fixture located on the fluid warmer and a pin-shaped fixture located on the fluid warmer of a fluid bag attachment assembly is also disclosed. Tubing guides present on the fluid warmer in conjunction with tubes of differing lengths attached to the fluid bag reduce the occurrence of usage errors during insertion of the fluid bag into the fluid warmer.

Abstract: A method for providing feedback on an expected and/or required user interaction in a blood purification device is disclosed. The method includes monitoring, at a current position in an operational flow of the blood purification device, whether a user interaction is expected and/or required in a subsequent step in the operational flow. If it is determined in the monitoring step that a user interaction is required and/or expected, the kind of required and/or expected user interaction is determined. A user interaction feedback indicating the determined kind of user interaction required and/or expected in the at least one subsequent step is then proactively activated at an active element corresponding to the user interaction in a graphical user interface.

Abstract: A method for providing animated feedback on an event state in a blood purification device is disclosed. The method includes detecting a pressed state of an active element on a graphical user interface of the device; triggering an event in the device in response to the detection of the pressed state of the active element; tracking the status of the triggered event, wherein said tracking includes detecting a plurality of states of the event, and wherein each detected event state is assigned a feedback representation variant at the active element; and setting the feedback representation variant at the active element as a user feedback indication in accordance with the detected event state. A device for performing the method is also disclosed.

Abstract: A method for providing feedback on user actions in a blood purification device is disclosed. Feedback may be provided by loading a task list defining process actions to be carried out into a processing environment of the blood purification device, wherein the task list includes at least one task assigned to a predetermined device and/or user action, selecting a set of sensors and/or detectors from sensors and/or detectors arranged in the blood purification device based on requirements of the task list, and for each task in the task list, querying the selected set of sensors and/or detectors, determining operational and/or device task states based on the sensor and/or detector outputs, and outputting a user feedback indication notifying the user on the determined task state. A blood purification device equipped with supporting hardware is arranged to carry out the method is also disclosed.
