USPTO Abstract
An apparatus for administering respirable pharmaceutical particles to at least one lung of a patient is disclosed. The apparatus comprises a ventilator (10) for cyclically forcing oxygen-rich air into at least one lung of the patient and collecting oxygen-depleted air exhaled by the patient. An inspiratory limb (30) is connected to the ventilator for carrying the oxygen-rich air from the ventilator to the patient, and an expiratory limb (40) is connected to the ventilator for carrying the oxygen-depleted air exhaled by the patient back to the ventilator. A Nebulizer (20) is connected to the inspiratory limb for introducing respirable pharmaceutical particles into the oxygen-rich air. A prefilter (42) is connected to the expiratory limb between the patient and the ventilator for removing respirable pharmaceutical particles from the oxygen-depleted air exhaled by the patient before it is returned to the ventilator.
