Abstract
A system for introducing a dose from a metered dose inhaler canister into the inspiratory stream (1B) of a ventilator system including an inspiratory tube (32), a Y connector (3), and an endotracheal tube (7) intubated in a patient, including a valved T connector (30) having a valved port (30A) and first (30B) and second (30C) ports coupled to conduct the inspiratory stream (1B) through the valved T connector, an MDI canister (14), and a nozzle adapter structure (31) having a first port (31A) for insertion into the valved port (31A) to open a valve thereof and a nozzle (31B) receiving a stem (14A) of the MDI canister (14) and ejecting a plume (17) of MDI medication particles upon activation of the MDI canister. A dry gas inlet (31D) receives dry gas which flows through the nozzle adapter structure (31) into the valved port (30A) and into the inspiratory stream (1B), and carries the plume from the nozzle adapter structure (31) through the valved port (30A) into the inspiratory stream (1B).
