Developing a reciprocating mechanism for the emergency implementation of a Mechanical Pulmonary Ventilator using an integrated CAD-MBD procedure

Following the COVID-19 outbreak, redesign of an emergency mechanical pulmonary ventilator that is cheap and easily portable became necessary in several contexts, such as hotspots environments with poor resources. To address this important issue, a general multibody approach employed paper to develop reciprocating mechanism suitable for retrofitting existing manual ventilators through computer-aided engineering tools. By analyzing various basic articulated mechanisms typically found mechanics, prototype created reproduced three-dimensional environment using SOLIDWORKS's CAD software. Subsequently, high-fidelity model developed starting from geometry employing SIMSCAPE MULTIBODY software, extension MATLAB family programs can effectively efficiently perform kinematic dynamic simulations interest. As discussed paper, by carrying out numerous numerical experiments, virtual predict fundamental medical parameters, airflow introduced into patients, respiratory rate, ratio.
