Abstract
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.
Claims20
A mobile medical device comprising:
- a motor-driven wheel configured to move the mobile medical device;
- a hub associated with the motor-driven wheel, wherein the motor-driven wheel is configured to be arranged on the hub;
- a locking device configured to connect the motor-driven wheel to the hub and to release the motor-driven wheel from the hub;
- grooves in the locking device, wherein the locking device is configured to rotate;
- corresponding guide elements on a circumference of the hub to engage in the grooves;
- and
- a handle on the locking device, wherein the handle is arranged on an end face of the motor-driven wheel facing away from the mobile medical device,
- wherein the handle is configured to rotate about an axis between a first position and a second position, wherein the handle extends out from the end face of the motor-driven wheel in the first position, and wherein the handle is positioned adjacent to the end face of the motor-driven wheel in the second position,
- wherein the locking device is configured to be twisted in a first direction by hand using the handle to remove the motor-driven wheel and the locking device from the hub, and
- wherein the locking device is configured to be twisted in a second, opposite direction by hand using the handle to attach the motor-driven wheel and the locking device to the hub.

A mobile medical device comprising:
- a motor-driven wheel configured to move the mobile medical device;
- a hub associated with the motor-driven wheel, wherein the motor-driven wheel is configured to be arranged on the hub;
- an axle on which the hub is arranged and rotatably mounted;
- a locking device configured to connect the motor-driven wheel firmly to the hub and to release the motor-driven wheel from the hub;
- a handle on the locking device, wherein the handle is arranged on an end face of the motor-driven wheel facing away from the mobile medical device;
- grooves on a circumference of the hub;
- and
- corresponding guide elements of the locking device configured to engage in the grooves,
- wherein the handle is configured to rotate about an axis between a first position and a second position, wherein the handle extends out from the end face of the motor-driven wheel in the first position, and wherein the handle is positioned adjacent to the end face of the motor-driven wheel in the second position, and
- wherein the locking device is configured to rotate to:
- (1) disengage the guide elements from the grooves to remove the motor-driven wheel from the hub by hand using the handle, or (2) engage the guide elements in the grooves to attach the motor-driven wheel to the hub by hand using the handle.
