The present embodiments provide a mobile medical device with at least one motor-driven wheel. The mobile medical device is movable on the at least one wheel. The motor-driven wheel is arranged on a hub assigned to the motor-driven wheel. The motor-driven wheel is reversibly removable from the hub and is pluggable back onto the hub manually and without aids. The present embodiments provide that the motor-driven wheel may be removed rapidly manually and without additional aids.

A fastening arrangement for a rim of a wheel on a wheel hub of a wheel carrier of a motor vehicle. The fastening arrangement includes a central screw which, on a fastening portion, has an external thread which engages in an internal thread of a step of the wheel hub. A tensioner produces a force-fitting connection between the wheel hub step and the central screw. A locking arrangement prevents unintentional release of the central screw. The locking arrangement has a carrier member and a blocking member, wherein the blocking member is pretensioned in relation to the carrier member by a locking spring member and is displaceable in the axial direction. The blocking member is arranged captively in the carrier member by a securing mechanism.
