ABSTRACT:
Apparatus is provided for injecting medication into a ventilator circuit. An elbow connects an endotracheal tube to the external ventilator circuit. A port in the elbow is connected to a flexible sheath leading to an actuator receiving an MDI canister. A catheter extends from the actuator substantially through the sheath to a position adjacent the elbow. When it is desired to inject medication, the actuator is moved to a position adjacent the elbow, thus projecting the discharge end of the catheter to a position within the endotracheal tube, but short of the open end thereof.
