Diseño e implementación de un sistema no invasivo de monitoreo de la presión arterial y de la frecuencia cardiaca combinadas: implementación mecánica, óptica y electrónica del tensiómetro.

Abstract

This project focuses on the implementation of a prototype capable of taking pressure and heart rate signals from a patient's wrist. The sizing, design, mechanical and electronic coupling of the prototype is presented. Based on the respective bibliography, the oscillometric method is used to determine the pressure and the oscillometric and photoplethysmographic method to determine the heart rate to transform these data into medical signals. The inflatable band and the digital sphygmomanometer piping system will be used as a mechanical base to adapt our electronic card controlled by the Arduino nano card that controls a micro pump, a solenoid valve, a pressure sensor, a heart rate sensor, a button, a LED and a system. feeding. The design of the card allows to have the measurements in real time of the process implemented for the oscillometric and photoplethysmographic methods to show them in the Labview interface, these data will be worked on to be able to obtain medical data of mean arterial pressure values in mmHg (millimeters of mercury), and the heart rate value in BPM (pulses per minute)
