Contribution to the design of hospital bed: Systematic for surveying the design requirements and functional requirements for synthesis of mechanism

Abstract

Hospital beds are of utmost importance in recuperations and welfare of bedridden patients. Not only providing comfort and safety, these equipment are also important in prevention and treatment of pressure sores. Healthcare works also benefits from adjustable hospital bed. These beds decrease the physical strain required from those workers, helping decrease musculoskeletal injuries. Fewer injuries handling patients provides a safer working environment. Initially is necessary to determine the user requirements, from interviews and market analysis. User requirements are hierarchized to determine which design requirement is most important in the user’s view, and these requirements are used to establish the functional requirements for synthesis of mechanisms. The survey signals to the development of mechanisms to movement bedridden patients that facilitate the patient transfer. Adding positions and functions to the product.
