Intelligent hospital bed and method for operating same
First Claim
1. An intelligent hospital bed comprising:
- a lower main frame,an upper frame provided with movable parts and articulated to the lower main frame, anda 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 includes multiple moving parts including;
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,the lower assembly including a raising/lowering mechanism articulated to the central support part of the upper assembly,wherein the pressure sensors are interconnected and associated with a control unit which controls multiple servo-motors adapted to move the movable parts of the upper frame, such that, when one or more of the pressure sensors detects a movement of the patient in real time, the control unit creates a map of pressure images to be processed to actuate specific servo-motors associated with the one or more of the pressure sensors for moving at least one of the movable parts of the upper frame; and
wherein the raising/lowering mechanism is adapted to be controlled by another of the servo-motors in order to control a linear up and down movement of the central support part,wherein each of the right side support part, the left side support part, and the central support part of the upper frame includes;
a fixed portion and an inclinable portion pivotally articulated to the fixed portion,the inclinable portions of the right side support part, the left side support part, and the central support part being linked to foldable sections of the mattress, wherein the intelligent hospital bed is configured to automatically recognize a pattern indicating and intention of the patient to sit up, lean back, or turn over from the map of pressure images, and to cause a movement of at least one of the movable parts of the upper frame in real time by action of the servo motors.

Abstract
The invention relates to an intelligent hospital bed comprising a lower main frame (1) and an upper frame (2) articulated to said lower main frame provided with movable parts, in which there is arranged a mattress (22) provided with several foldable sections, including a plurality of sensors arranged along the mattress (22) capable of measuring the initial force on the point at which the corresponding sensor is arranged, which sensors are interconnected to one another and associated with a control unit which controls servo-motors used for moving the movable parts of the upper frame (2) such that when a sensor detects a movement of the user in real time, a servo-motor which is associated with a corresponding sensor or a combination of sensors (S) moving at least one of the movable parts of the upper frame (2) is actuated.
