Sistema de automatización y control para una silla-bipedestadora en el Centro de Rehabilitación Física Bendiciones

Abstract

ABSTRACT The use of assisted mobility equipment for people with physical disabilities allows the integration of these people into society and interaction with their daily lives. For this reason, this project focuses on improving the process of changing the state of a wheelchair to a standing frame by designing an automation and control system for a standing frame for the rehabilitation center "Bendiciones". The present project describes the design of an automation and control system incorporated in a wheelchair - standing frame, whose owner is Mr. Cristian Núñez who has 90% of physical disability caused by paraplegia. In order to carry out this project, a mechanism that adapts to the characteristics of the wheelchair is required, since in principle the chair works manually and was designed with that sole purpose in mind. The elevation mechanism and the system to be implemented must not alter the physical structure of the two-legged chair, nor must it interfere with its main operation. The operation of the automation and control system of the Standing Frame consists of the use of a mobile mechanism that allows the vertical displacement of the wheelchair, supporting the weight of the structure, as well as the patient's body weight. The movement of this mechanism must provide a linear and stable movement, besides having a manual control that allows operating the vertical movement of the chair without the need of assistance personnel and above all, providing free mobility in the change of the patient's posture. As a result, there will be an efficient system implemented in the two-legged wheelchair that performs this process in an automated and controlled way, keeping the integrity and good functioning of the working devices, covering with this the specific needs of the patient.
