Item Desarrollo de un sistema para la gestión de mantenimiento de equipos biomédicos en el hospital san antonio de barbacoas, nariño(Universidad Santiago de Cali, 2022) Olaya Angulo, Jhonnier Andres; Rodríguez Estacio, Yonier Boanerges; Bermeo Varón, Leonardo Antonío (Director)The maintenance management of biomedical equipment in health care institutions plays an important role in providing quality service. Its implementation will make it possible to know the status of biomedical equipment through indicators, such as equipment availability, compliance with maintenance goals, and everything about its technology, which will result in a better service. Currently, information systems through specific systems and database management allow optimal management for the quality service provision. In particular, the San Antonio Hospital located in the department of Nariño in the municipality of Barbacoas does not have adequate management systems and performs this work using excel spreadsheets, which generates problems in aspects such as security, updating, and lack of control of the information. In addition, the high flow of information causes problems with filters and migration of information to another system, which can lead to loss of information or simply not transferring the data to other formats. Thus, in this work, we developed a system for the management of biomedical equipment maintenance called SYSGEB to be implemented in the Barbacoas Hospital. The system is made in PHP programming language in the Visual Studio Code platform, it is a web application that has a web server and MySQL database. SYSGEB has functional modules that allow keeping the equipment inventory, management indicators, maintenance schedule, reports, equipment lifecycle, alarms, and warehouse and user control. For its validation, preliminary functionality and system appreciation tests were carried out using the test cases method, as well as a usability test using the EUS (System Usability Scale) method. The results indicate that SYSGEB has the necessary parameters to carry out the maintenance management of biomedical equipment in favor of quality service and with a high percentage of effectiveness of use and satisfaction on the part of the people involved in the systemItem Sistema para la ubicación, sujeción y adquisición de señales mioeléctricas para el desarrollo de prótesis de amputación transhumeral(Universidad Santiago de Cali, 2022) Valencia Palacios, Angie Clarena; Bermeo Varón, Leonardo Antonío (Director)Myoelectric signal acquisition systems are currently of great benefit in research and the clinical field and rehabilitation. The prosthesis control with myoelectric systems is considered one of the best-known schemes with multiple benefits for people with different types of amputation. This is of a great interest since the arrangement, adjustment, and ergonomics of the mechanism that allows the distribution of the sensors, becomes a fundamental part in the control of prosthesis efficiency. In the present work is developed a system of location, fastening, and acquisition of myoelectric signals for prosthesis of a transhumeral amputation patient to avoid loosening, misadjustment, and fall of sensors. Additionally, to improve the electromyographic acquisition. System testing was performed on 6 (5-1) non-amputees and transhumeral amputees to evaluate the stability, ergonomics, and signal acquisition efficiency. The subject performed the gestures of (i) elbow flexion, (ii) elbow extension, (iii) forearm pronation, (iv) forearm supination, (v) hand opening, and (vi) hand closing. Is realized the feature extraction corresponding to rectified signal, mean absolute value, root mean square, and variance. The results indicate that the acquisition system replaces the tedious and time-consuming conventional acquisition protocols with adequate feature extraction.
