Abstract: An apparatus for a safety-relevant application and a method for operating the apparatus. The apparatus has a user interface to display digits. The digits are intended to be filled with numerical values by a user. The user interface is designed to limit a selection of digits available for a user input when a numerical value is input by the user, for example the user's first input, for one of the digits that are to be filled.

Abstract: A medical fluid pump of the infusion or syringe pump design includes a fluid pump housing which includes a display unit, in particular a display or touch display, with a plurality of display panels that are prepared and configured to display at least one respective function parameter of the fluid pump, including at least one setting parameter which can be set directly by a user of the fluid pump and a plurality of operating parameters which cannot be set directly by the user. The representation of the at least one setting parameter stands out visually against the operating parameters, such as by displaying the at least one setting parameter in an enlarged size compared to the operating parameters.

Abstract: A medical pump system includes at least one medical fluid pump of a first type and at least one medical fluid pump of a second type. The medical fluid pumps can be assembled or arranged vertically, with one of the medical fluid pumps positioned above the other. Each medical fluid pump has a movable front flap with an integrated display and operating elements. The medical fluid pumps can be directly connected to one another in a vertical arrangement, or arranged in a vertical arrangement with the aid of a carrying or holding device. When the medical fluid pumps are vertically arranged, the displays and operating elements of the respective medical fluid pumps are aligned vertically.
