Abstract
An inhalation therapy device includes a collapsible aerosol storage bag ( ) having an opening which connects to the end of a dual port member, one port ( ) of which is in fluid communication with a nebulizer. During patient exhalation the aerosol storage bag becomes partially inflated with exhaled gas during the first part of exhalation. The laminar coherent aerosol jet exits the dual port member and remains coherent until reaching the end of the aerosol storage bag, at which time it diverges and expels all exhaled gas from the aerosol storage bag, thus filling the aerosol storage bag with aerosol. All escaping gas exits the aerosol storage bag via the remaining port ( ) of the dual port member, where it escapes into the ambient environment through the ambient port. The remaining dual port of the dual port member, in addition to providing means for escaping gas from the aerosol storage bag, is also in fluid communication with the ambient port and the mouthpiece ( ). Upon inhalation, the patient inhales the aerosol within the aerosol storage bag, the aerosol produced by the nebulizer during inhalation, and ambient air through the ambient port. The cycle is than repeated indefinitely.
