Ventilator valves are external attachments that supply oxygen at predetermined concentrations to patients suffering from COVID-19 or acute respiratory distress. Single-use valve sets can be printed using three-dimensional printing technology via a filament extrusion system or a polymer laser powder bed fusion process, and 3D printers can design the different elements of the valve using biomaterials like polyamide and polysulfone, polycarbonate, silicone rubber, and stainless steel. These disposable valves also eliminate the need for time-consuming sterilization. This paper discusses CFD simulations and design improvements in Venturi, splitter, and Charlotte valves based on basic flow quality factors.
