1. A cleaning and/or disinfection system (8) of a hollow tube (4), comprising:
the hollow tube (4);
a ring (18) mounted so as to slide over the hollow tube (4), the ring (18) enclosing an absorbent pad impregnated with a disinfecting and/or degreasing liquid, the absorbent pad being arranged around the hollow tube (4);
an electromechanical actuating device (20) of the ring (18) arranged inside the hollow tube (4), said device (20) including a longitudinal translational drive element (26), wherein the electromechanical actuating device (20) is a motorized linear potentiometer;
a longitudinal slot (11) is provided in the hollow tube (4), the longitudinal translational drive element (26) protruding through said longitudinal slot (11) and being mechanically connected to the ring (18), in order to move the ring (18) in longitudinal translation along the hollow tube (4);
characterized in that the hollow tube (4) is a lever for operating a door handle (2);
the system (8) also comprises a reservoir (16) of liquid disinfectant and/or degreaser, the ring (18) being integral with the reservoir (16), and the absorbent pad being in fluid communication with the reservoir (16);
the ring (18) and the reservoir (16) form a single piece; and
a first opening (22A) is provided in the ring (18) facing the absorbent pad, said opening (22A) leading into the reservoir (16), the reservoir (16) and the first opening (22A) being configured so that liquid flows from the reservoir (16) to the absorbent pad through the first opening (22A), when the lever is inclined downward.
