Construcción de un dispositivo electrónico portable para la supervisión de signos vitales de personas alejadas a los servicios de salud.

Abstract

A portable electronic device was implemented for the supervision of vital signs of people far from the health services, for the development of the prototype the following stages were taken into account: acquisition, data visualization and the alert stage. In the data acquisition stage, the XD-58C heart pulse sensor, MLX90614 temperature sensor, microphone to obtain respiration data and the MPX500P heart pressure sensor, and the Arduino Nano microcontroller were used for data processing. In the visualization stage, a serial communication was used that sends data to the mobile graphic interface in which the values of vital signs can be observed, in addition, a Wifi communication was implemented to send data to an online computer tool to be able to be visualized and analyzed by the medical staff in charge. Finally, in the alert stage, a data transmission block was used, in charge of issuing the alert message to the medical personnel in charge if vital signs were obtained out of the ordinary. In the results of the implemented prototype, all the requirements raised are met, having an autonomy of 2 hours with 14 minutes, enough time to be able to analyze vital signs of a patient, through the repetitive technique we have a coefficient of variation (CV) of less than 10 %, concluding that it is a stable device in all its measurements. It is recommended to obtain a better duration in the power supply of the solar panels device.
