Abstract
Disclosed herein is a ventilator text fixture comprising a ventilator port that connects to a ventilator through a breathing circuit; where the ventilator delivers air through the ventilator port to a ventilator test fixture at a rate and pressure that can be controlled by a user to simulate inhalation; an input port; where the input port is in fluid communication with the ventilator port; where the input port permits additional simulated secretions or test liquids to be pumped into the ventilator text fixture; one or more bent supports; a liquid reservoir; where the liquid reservoir is operative to hold test fluids; and one or more tubes; where the one or more tubes are in fluid communication with the ventilator port and the input port via the liquid reservoir; and where the one or more bent supports are operative to mimic an anatomy of the trachea.
