Abstract

The aim of this work is to design and control of a mechanical ventilator with the simplest strategy that satisfies the need for low-cost mechanical ventilation. This design should be rapidly manufactured in large quantities to make it possible to safely ventilate a COVID-19 patient. The process in approaching that, is to first identify the minimum requirements for a low-cost ventilator, based on the information of many clinicians with respect to the design against these requirements, conducting immediate testing, reporting the results. Two different ventilator concepts are proposed, such that the ventilator can be operated in case of a pressurized air-oxygen mixture is available or not. The proposed design is inspired by medical professionals and adult patients battling COVID-19. It allows gentle air delivery to the patient with capability for both volume control and pressure support modes. The mechanism design is user-friendly and easy to manufacture, the sophisticated control system ensures flexible inputs, patient data monitoring, and various levels of alarms. Simulation results and experimental work are presented and have shown to be applicable compared to previous works.
