Diseño y construcción de un mouse adaptado al miembro superior afectado con secuela de mano espástica

Abstract

In order to enable access to assistive technology, this project focuses on the design and construction of a mouse adapted for the upper limb affected by spastic hand sequelae. The purpose is to provide an adapted work tool that allows the use of Information and Communication Technologies (ICT) in Ecuador. For the development of the mouse prototype design and construction, we began with a study of several assistive mice for individuals with spastic hand sequelae, based on analysis of alternative materials, accelerometers, and connectivity for construction. These concepts are presented in Chapter 1. Based on the concepts gathered in Chapter 1, a proposal for three alternatives for the mouse prototype design is generated. These proposals are evaluated using criteria rating tables, which allowed us to select the best alternative for the development of this project. Furthermore, based on the rating table criteria, the best material, microcontroller, connectivity, and accelerometer are selected. These alternative selections are presented in Chapter 2. Using Blender software, the 3D modeling was designed to subsequently ensure proper printing in flexible filament and PLA. These materials were selected using the material rating tables for this prototype. With the prototype design in place, the implementation in conjunction with mechatronic elements for the prototype's operation is detailed in Chapter 3. To validate the functionality of the mouse prototype, multiple tests were conducted with patients suffering from spastic hand disease. These tests yielded positive results, as shown in Chapter 4, demonstrating the prototype's functionality. Finally, the conclusions and recommendations of this project are presented.
