Abstract: Method of producing an administering device for infusing or injecting a product, whereby in order to mold a housing shell (1) serving as a case for components of the administering device in a multi-component injection molding process at least one pre-molded, transparent insert part (22, 23) made from a first plastic material is inserted in an injection mold molded to a shape matching the shape of the housing shell (1), a dimensionally stable, curable second plastic material is injected into the injection mold around the insert part (22, 23) to render it watertight and an opening left free in the second plastic material is closed to render it watertight by injecting on an elastomeric third plastic material.

Abstract: Administering device for infusing or injecting a product, comprising a housing (1, 2) with a first housing shell (1) and a second housing shell (2), a receiver (3) for the product formed in the housing (1, 2), a conveying mechanism (4) for conveying the product and a seal (10), which connects the housing shells (1, 2) to one another in a pressing contact rendering them watertight, which seal (10) is or has a sealing lip (13) which establishes the pressing contact with the first housing shell (1).

Abstract: Administering device for infusing or injecting a product, comprising a housing (1, 2) with a receiver (3) for the product, a compartment (7) for a power source in order to supply the conveying mechanism (4) with electrical energy, a first contact spring (15) which is disposed in the compartment and places a terminal of the power source in an electrically conducting contact by means of a spring force when the power source is disposed in the compartment (7), and a second contact spring (16) for establishing an electrically conducting contact for an opposite terminal of the power source, likewise by means of spring force.

Abstract: A device including a display for displaying operational and/or functional parameters of the device and a control unit with at least one control element for controlling the display and/or device, wherein the display is at least partly rotatable with respect to the device, and/or wherein the position of the at least one control element is modifiable or changeable with respect to the device. In some embodiments, the control functions of at least two control elements of the device are interchangeable. In some embodiments, the display is provided by data sent to the display at intervals, whereby the display is updated. In embodiments in which several display parts are rotatable, data is processed by a processing module prior to being sent to the display. A method of display and/or display and control manipulation is encompassed.
