Implementación de un prototipo de un sistema de red biométrica para el control de saturación de oxígeno con la tecnología bluetooth.

Abstract

The objective of this Titulation Work was the design and implementation of a prototype of a biometric system, with Bluetooth 2.4GHz technology, which allows the measurement of oxygen saturation in the blood, with the registration and sending to a mobile application (Android) and later, sending it to a database in a web page. The construction of the prototype was in two stages, the transmitter that is made up of four devices similar to a watch, in which the oxygen saturation levels are displayed in real time, both in percentage and in a graph of the variation of the same, values which are sent by the HC-05 Bluetooth modules and received by the next stage, the receiver, made up of a mobile application, and a database, which have a user-friendly graphical interface, where the data is displayed patient's personal data, as well as oxygen saturation levels. For the taking of results, the use of two market oximeters was considered, which were compared with the results obtained with the prototype, in two different scenarios, the first scenario was when the people were at rest, that is, about 10min before take the measurements, and in the second scenario it was attempted to perform the measurements after a physical activity. Finally, it was concluded that the prototype works and optimizes the time of doctors when it comes to monitoring the health of the patient and it is recommended to use this prototype to avoid direct contact with a patient, and monitor him or her remotely effectively and efficiently.
