A Robotized Bed for Bedridden Patients

Abstract

Longtime bedridden patients may have serious problems from the immobilization and a reposition of their body can be often request at least to mitigate effects in pulmonary complications and pressure ulcers. This paper approaches the problem on how to give basic movements to those patients to help in those situations by permitting body repositioning through movements of bed segments. The solution is proposed in term of design of structure and control of a robotized hospital-type bed in which the bed structure is portioned in segments that are properly activated and controlled by a specific mechanism with a specific controlled operation. The proposed solution is tested and characterized via simulations whose results verify the feasibility and efficiency of the proposed solution for a future implementation in hospital frames.
