Resumen (en)
In this article, it is proposed a prototype oriented to nurse-call, which allows to create and inform the request of emergency care of a patient to the public, by means of embedded devices like the Raspberry Pi and a Display Touchscreen LCD. The emergency call is carried out by means of a network of switches that activate a channel, then this signal is conditioned and processed to be transmitted by means of a serial bus RS-485, then the received message is decoded and shown on an LCD screen, finally the request information is stored in a database. Some experiments were conducted to evaluate the energy consumption, the rate of data loss, the scope, as well as tests to validate the scalability of the prototype. The results show that the proposal presents an increase in the demand of electric energy, mainly due to the characteristics of the technology used, however, the results show that the designed system allows to quantify the dynamic in the time of the nurse-call and is compatible with other similar systems.
Resumen (es)
En este artículo se propone un prototipo orientado al llamado de enfermería el cual permite generar e informar la solicitud de atención de emergencia de un paciente al público por medio de dispositivos embebidos como las Raspberry Pi y un Display Touchscreen LCD. El llamado de emergencia se realiza por medio de una red de pulsadores que activan un canal; luego, esta señal es acondicionada y procesada para ser transmitida por medio de un bus serial RS-485; después, el mensaje recibido es decodificado y mostrado en una pantalla LCD; finalmente, la información de la solicitud es almacenada en una base de datos. Se realizaron experimentos para evaluar el consumo energético, la tasa de pérdida de datos, el alcance, así como pruebas para validar la escalabilidad del prototipo. Los resultados muestran que la propuesta presenta un aumento en la demanda de energía eléctrica debido, principalmente, a las características de la tecnología utilizada; sin embargo, los resultados muestran que el sistema diseñado permite cuantificar la dinámica en el tiempo del llamado a enfermería y es compatible con otros sistemas similares
