Dry powder inhalation device having deagglomeration/aerosolization structure responsive to patient inhalation

Abstract

An inhalation device for dry powder containing a chamber capable of receiving a dose of powdered medicament. The chamber is in communication with a patient port in the form of a mouthpiece or nasal adapter. The inhalation device also contains a deagglomeration/aerosolization apparatus capable of deagglomerating and/or aerosolizing a dose of powdered medicament and is operable by a patient-independent energy output source. The inhalation device further includes detection apparatus that ascertains patient inspiration through the patient port, and a control apparatus that actuates the deagglomeration/aerosolization apparatus in response to detection of patient inspiration.
