Design and Fabrication of Low Cost Modified Maneuverable Standing Stretcher Wheelchair Transport System

Abstract

Wheel Chairs are one of the convenient man made structure which are highly useful for person with disability. The major problem of this wheelchair is the architectural obstacles such as stairs etc. Many researchers around the globe have worked on wheel chair design so as to make the user independent. The question of overcoming these obstacles by a wheelchair always is the most discussed topics in recent days.

This paper involves in fabricating a wheel chair which is motor operated. It is stair climbing wheelchair design which concept which overcomes the structural obstacles. The fabrication of an ergonomically designed battery operated wheel chair for multi usage is done.  Concept of stairs climbing function is embedded in the design by adopting new design and mechanism. The design considerations of the wheelchair are based on the standard design of the stairs which are constructed in India. The work deals with design and fabrication of wheelchair convertible to bed. It is also equipped with a standing aid which helps the disabled individual to stand up and perform certain work.

The design involves the  use of electrical linear actuators which consists of an assembly of motor driven power screw to make the transformation from sitting to a bed by using a hand held remote, overcoming the need of a another person to shift the patient from wheelchair to bed. This project offers multiple features over a standard wheelchair and is very economical in comparison to commercially available wheelchairs.
