Abstract: A hose mount of a blood treatment machine, having a hose connection element as a component of the machine's internal hosing including at least one rigid sleeve portion that is adapted to position a flexible hose radially outside over the free end of the at least one sleeve portion, an axial stop formed or arranged on the outer circumference of the sleeve portion at a distance from the free end, and a flexible collar arranged or formed on the at least one sleeve element toward the free end with an axial distance to the axial stop in order to define an external circumferential groove between itself and the axial stop.

Abstract: The disclosure relates to an inverter having a first housing module, a second housing module, removably connected to the first housing module, and power-electronic components in both housing modules, wherein a cooling air channel, opening in the surroundings of the inverter, is delimited in the circumferential direction partially by the first housing module and partially by the second housing module. The first housing module is configured to mount to an external structure and the second housing module is configured to mount to the first housing module. The cooling air channel extends at a distance to a mounting plane of the inverter defined by the first housing module opposite the external structure.

Abstract: An electronic device is provided with a base as a first housing part and a cover as a second housing part, the first housing part and the second housing part being formed at least partially from conductive material. In an assembled state, the electronic device is electrically connected by a fastening pair respectively belonging to one of the two housing parts, the fastening pair having a pin with at least three pressure edges and a recess with an opening cross section adapted to the pin. In the assembled state, the pin protrudes into the recess in such a way that a holding force between the two housing parts is exerted between the pressure edges and the walls of the recess.
