Design and Development of Mechatronic Emergency Ventilator for Treating Breathing Ailments

Abstract: This paper presents the design and development of a mechatronic emergency ventilator for treating breathing ailments. The system was developed to address the increasing demand for ventilators due to the COVID-19 pandemic. The ventilator consists of a mechanical system that provides the necessary air pressure and volume to the patient, and an electronic control system that regulates the respiratory rate and tidal volume. The system was designed with simplicity, portability, and cost-effectiveness in mind, using off-the-shelf components whenever possible. The stepper motor is interfaced with a stepper drive in order to impose a "PUSH-PULL" mechanism to run the AMBU bag, and Arduino is used to interface all of the sensors, motor, and supply. The "PUSH-PULL" technique is used to equalize air pressure. This meets every demand and requirement for the patient with Covid-19.
