Device (1) for handling a stretcher suitable to be installed in a helicopter cockpit for displacing the stretcher between a patient transportation position, in which the stretcher is arranged horizontally and parallel to a longitudinal axis (AL) of the helicopter, and a patient loading and unloading position in which the stretcher is at least partially removed from the helicopter cockpit substantially transversely to said longitudinal axis (AL), and vice-versa. The displacement of stretcher can be motor-driven and includes a vertical displacement device (14, 15, 16) of the stretcher in said loading and unloading position between a raised condition and a lowered condition which keeps the stretcher substantially horizontal,
