Design of multi-functional bed for bedridden patient

This paper presents a novel design of a multi-functional bed for the bedridden patients, including elderly and maim persons. Most patients encounter difficulty in posture changing and moving. To overcome these problems, the proposed design conception is validated through the consolation with medical staff as well as from literature survey. A belt system is designed for transferring patient from the bed to a wheelchair. The bed mechanism design is analyzed first by the detailed mathematical model and related design parameters and functionalities are verified by the computer aided design software: Solid Works. Finally, simulation results demonstrate the effectiveness of the proposed design approach for solving these two problems.
