Sistema de control de temperatura aplicado a la solución salina, para reducir los efectos de hipotermia durante la anestesia en cirugía.

Abstract

The heating of intravenous fluids has a very important task in medicine, since it prevents complications that can have serious consequences in patients. Currently there are equipment that offer heat fluids, with the disadvantage that such equipment are very expensive, work in open loop and also have no control over the heating system; As a more feasible option, a team has been developed that provides many more benefits in order to achieve a more controllable, more economical and closed loop system. The equipment works from a system PID worked in Arduino and the heating of a ceramic cartridge whose task is to reach the temperature set by the anesthesiologist, and then transfer the heat to a conductive material in which it is also coupled the fluid path that will enter the patient, thus heating the saline solution and being this sensed at the exit of the path to have temperature control of entrance to the human body.
