Abstract
Con el enfoque en el desarrollo de una tecnología de monitorización para caninos, se ha optimizado un prototipo de dispositivo wearable para monitorizar la frecuencia cardíaca en perros. Abordando las limitaciones de un prototipo previo que presentaba interferencias en la lectura de señales ECG debido al uso de electrodos adhesivos con el pelaje, carecía de conectividad inalámbrica y tenía un diseño poco ergonómico. Siguiendo una metodología basada en el modelo en V, se realizaron ensayos clínicos en 10 perros para cada prototipo (existente y optimizado), comparando las mediciones con métodos tradicionales como auscultación, electrocardiograma y monitores con módulos de BPM. También se realizaron comparativas entre señales registradas por prototipo y encuestas al personal médico para la validación del prototipo por etapa. El prototipo optimizado incorporó electrodos impresos en 3D de PLA conductivo, un nuevo código en Arduino IDE que ofrece una alternativa para el conteo de picos R y realizar el cálculo de FC y habilita la comunicación inalámbrica BLE, y un diseño en forma de cinturón ajustable para mayor comodidad. Los resultados mostraron una mejora significativa en la precisión del prototipo optimizado, con una disminución del margen de error del 14.71%. Los electrodos impresos en 3D demostraron ser funcionales, aunque se identificó la necesidad de mejorar su sensibilidad, evidenciado por la poca variabilidad en las señales. La comunicación inalámbrica BLE funcionó correctamente, permitiendo visualizar los datos de FC en tiempo real. Y las encuestas validaron un avance significativo comparado a la versión previa. El prototipo optimizado representa un avance en el desarrollo de una tecnología de monitoreo no invasivo para perros, con potencial aplicación clínica
With the focus on the development of a monitoring technology for dogs, a prototype of wearable device for monitoring heart rate in dogs has been optimized. Addressing the limitations of a previous prototype that presented interference in reading ECG signals due to the use of adhesive electrodes with fur, lacked wireless connectivity and had an unergonomic design. Following a methodology based on the V model, clinical trials were conducted on 10 dogs for each prototype (existing and optimized), comparing the measurements with traditional methods such as auscultation, electrocardiogram and monitors with BPM modules. Comparisons were also conducted between prototype signals and surveys of medical personnel for phase-by-phase prototype validation. The optimized prototype incorporated 3D printed electrodes of conductive PLA, a new code in Arduino IDE that offers an alternative for R peak detection and performing HR calculation and enables BLE wireless communication, and an adjustable belt-shaped design for greater convenience. The results showed a significant improvement in the accuracy of the optimized prototype, with a decrease in the error margin of 14.71%. The 3D-printed electrodes proved to be functional, although the need to improve their sensitivity was identified, evidenced by the low variability in the signals. The BLE wireless communication worked properly, allowing the viewing of HR data in real time. And the surveys validated a significant advance compared to the previous version. The optimized prototype represents progress made in the development of a non-invasive monitoring technology for dogs, with potential clinical application.
