Desarrollo de un prototipo de respirador automático emergente para pacientes con dificultad de respiración

Abstract

The objective was to develop a prototype of an automatic respirator to help patients with respiratory deficiency in accordance with the medical requirements established in the ASTM F920-93 standard and the ARCSA specifications. The high rate of coronavirus infections at the national level means that those who fight against the virus suffer from respiratory failure, and being a very large number of infected has caused the health system to collapse and for this reason many patients cannot access to a hospital gurney where they can be assisted with artificial respiration. Pressure-controlled ventilation has been chosen, which will depend directly on the respiratory rate set by the patient. With the application of Conceptual Design, it has been possible to capture the most important needs that the user has in technical specifications of a breathing apparatus. The equipment is composed of an ambu bag that is compressed by a pair of arms that are directed by a gear train, the necessary torque is 60 kgf-cm, this servomotor is controlled by an electronic system that depends directly on the respiratory rate. By means of a pressure sensor the signal is sent that the equipment has reached the calculated pressure value and the process ends, it will automatically start the expiration process considering the time relationship between the I: E suitable for the patient in treatment. It is recommended to keep the equipment in a free space where its maintenance and sterilization is easy to carry out, as well as taking care in the way of operation that is given to the equipment to achieve the highest possible efficiency. The elements susceptible to failure after a long working time are the shaft and the gears because they are subjected to fatigue efforts.
