The invention pertains to a computer-implemented method for evaluating a user interface (UI) of a medical device. The method involves the collection of sensor data, both textual and non-textual, during the use of the UI, which reflects the user's satisfaction with the interface during interaction. The non-textual sensor data is transformed into textual format, and all received sensor data is aggregated in a textual format. This aggregated data is then input into an assessment algorithm, which continuously determines an assessment dataset. The resulting dataset is then displayed on a result interface. The medical device can be any technical device used for medical purposes, such as a dialysis or plasmapheresis device. The UI can be a variety of interfaces, including a graphical user interface (GUI), a gesture-based interface, a voice interface, or a keyboard, and can be implemented directly in the medical device or in a separate device in data exchange with the medical device. The sensor data can come from various sensors, including text data, voice data, data from a virtual sensor, and image data from an optical sensor.

The present invention provides a first and a second a system for connecting a pipe of an extracorporeal circuit to a pressure transducer interface, the system comprising a transducer protector and an adapter, the transducer protector comprising a first main body comprising a first fluid path, a first connector for fluidly coupling a first end of the first fluid path to the pipe of the extracorporeal circuit, a second connector for releasably coupling a second end of the first fluid path to the adapter, and a hydrophobic gas-permeable membrane arranged in the first fluid path for separating the first end of the first fluid path from the second end; the adapter comprising a second main body comprising a second fluid path, a third connector for releasably coupling a first end of the second fluid path to the first fluid path of the transducer protector, and a fourth connector for releasably coupling a second end of the second fluid path to the pressure transducer interface. The second connector is a snap-fit connector and the third connector comprises a snap-fit counter-element for the second connector, or the fourth connector is a snap-fit connector configured to be connected to a counter-element of the pressure transducer interface.

The present invention comprises a transducer protector for an extracorporeal circuit, comprising: a main body comprising a fluid path; a first connector for fluidly coupling a first end of the fluid path to a pipe of the extracorporeal circuit; a second connector for fluidly coupling a second end of the fluid path to a pressure transducer interface; and a hydrophobic membrane arranged in the fluid path for separating the first end of the fluid path from the second end; wherein the second connector is a bayonet connector.

Tubing connector having an inlet for a liquid and an outlet for the liquid as well a first tubing connector element and a second tubing connector element, wherein the inlet and the outlet. The connector comprises at least one first pressure measurement chamber for measuring the pressure of the liquid which is present in said first wherein the first chamber is fluidly arranged between the inlet and the first tubing connector element or between the outlet and the second tubing connector element. The measuring surface is arranged in an angled orientation w.r.t to pumping plane. Further, a blood treatment device is adapted to accommodate the tubing connector.

Die vorliegende Erfindung betrifft ein Verfahren zum Durchführen einer Abfrage eines Spezifikationsmerkmals, welches in, an oder auf einer medizintechnischen Funktionseinrichtung angeordnet ist, mit dem Schritt: Abfragen des Spezifikationsmerkmals mittels einer mit der medizintechnischen Funktionseinrichtung funktionell gekoppelten oder zu koppelnden medizintechnischen Behandlungsvorrichtung oder einer hiermit in Signalübertragung verbundenen oder stehenden Einrichtung. Sie betrifft ferner eine medizintechnische Funktionseinrichtung, eine medizintechnische Behandlungsvorrichtung sowie eine Steuereinrichtung. Des Weiteren betrifft die vorliegende Erfindung ein digitales Speichermedium, ein Computer-Programm-Produkt sowie ein Computer-Programm.

The present invention provides a connector for positioning a pump hose segment in a pump bed of a medical peristaltic pump, characterized in that an optical data code, in particular a one-dimensional or two-dimensional barcode, is arranged on the connector.

A simulated cannula for a self-cannulation training system is provided. The simulated cannula includes a coupler that houses an LED light source and includes an electrical conductor and an optical fiber extending therefrom. The coupler can couple to a off-the-shelf cannula that can be easily modified for such purpose. The training system also includes a cannulation pad, a control unit, and first and second indicators. The control unit can include a rechargeable battery. The first indicator is activated when the cannula needle electrically completes the cannulation electrical circuit. The second indicator is activated when the cannula needle infiltrates or bypasses the simulated access and completes the infiltration electrical circuit. Methods of training a patient for self-cannulation, using the simulated cannula and training systems, are also provided.
