Estudio y Construcción de un Sistema Ventilatorio Pulmonar Controlado.

Abstract

It was necessary to design and build a controlled-pulmonary ventilator system in Fagove Enterprise, whose price is cheap and meet the requirements of the existing equipment in the market that is why this system was designed and built by research and scientific methods comparing the different existing systems to select the best components. This prototype was developed by tactile screen of 7 inches, an Arduino development plate, pressure sensors, electro valves, regulator valves, pressure valves and regulated source. By combining all these elements, monitoring of the parameters to be controlled by sensors was gotten as a result, activating actuators if necessary in order to fulfill the exhalation and inhalation cycles. This precedure is carried out with oxigen and air. Proportional electro valves were used to control the flow managed by means of interface. By this investigation, ventilator equipment was built with good results, wich mean 7% less in sensibility of the sensors achieving the objective of this paper in order to apply tests of calibration necessary for the use. It is concluded that in this country, equipment with similar characteristics to the current ones can be developed reducing production costs. Therefore, it is recommended to give maintenance of the equipment regularly.
