Intelligent hospital bed and method for operating same

An intelligent hospital bed comprising:

• a lower main frame,
• an upper frame provided with movable parts and articulated to the lower main frame, and
• a mattress provided with several foldable sections on which a patient rests, the mattress including a plurality of pressure sensors arranged along the mattress capable of measuring the initial force of the patient at a point at which the corresponding sensor is arranged,
• wherein the upper frame comprises:
• a lower assembly articulated to the lower main frame in at least two pivot points located at opposite ends of the lower main frame;
• and
• an upper assembly on which the mattress rests, the upper assembly being provided with a right side longitudinal support part, a left side longitudinal support part, and a central support part which are connected to each other, the left and right side longitudinal support parts being connected to and respectively articulated to left and right lateral ends of the central support part, such that each of the support parts is capable of being inclined,
• wherein the pressure sensors are interconnected and associated with a control unit which controls servo-motors used for moving the movable parts of the upper frame, such that when one or more of the sensors detects a movement of the patient in real time, the control unit creates a map of pressure images to be processed to actuate the specific servo-motors associated with the one or more of the sensors for moving at least one of the movable parts of the upper frame;
• and
• the lower assembly includes a raising/lowering mechanism articulated to the central support part of the upper assembly which allows movement of the central support part linearly up and down, and the raising/lowering mechanism being controlled by another of the servo-motors.
