Abstract
An inhalation apparatus for medicinal use which will deliver aerosolized medication to the patient that comprises up to about 80% of the medication aerosolized in essentially the same particle size distribution of the aerosol mist that originates from the nebulizer which produces the mist. The apparatus also provides delivered dose consistency over a wide range of patient breathing parameters.
Claims20
An aerosol inhalation apparatus for delivering a medicament containing mist to a patient comprising:
- (a) a housing including:
- (i) a first chamber having an inlet, an outlet and baffle means for providing a circuitous fluid flow path through said first chamber;
- and
- (ii) a second chamber having an inlet in communication with said first chamber and an outlet;
- (b) nebulizing means connected to said housing for communication with said first chamber for nebulizing a fluid medication containing the medicament to produce a particulate laden spray and for introducing said particulate laden spray into said first chamber;
- (c) a first flow control means for controlling fluid flow outwardly of said outlet of said first chamber;
- and
- (d) a second flow control means for controlling fluid flow between said outlet of said first chamber and said second chamber.
An aerosol inhalation apparatus for delivering a medicament containing mist to a patient comprising:
- (a) a housing including:
- (i) a first chamber having an inlet, an outlet and baffle means for providing a circuitous fluid flow path through said first chamber;
- (ii) a second chamber having an inlet in communication with said first chamber and an outlet;
- (iii) a third chamber having an inlet in communication with said second chamber and an outlet in communication with said first chamber;
- (b) nebulizing means connected to said housing for communication with said first chamber for nebulizing a fluid medication containing the medicament to produce a particulate laden spray and for introducing said particulate laden spray into said first chamber;
- (c) a first flow control means for controlling fluid flow between said outlet of said third chamber and said first chamber, said first flow control means comprises a pivotally mounted valve member for controlling fluid flow through said outlet of said third chamber;
- and
- (d) a second flow control means for controlling fluid flow between said outlet of said first chamber and said inlet of said second chamber, said second flow control means comprising a flapper valve pivotally mounted proximate said inlet of said second chamber for controlling fluid flow through said inlet.
The combination of a ventilator having an inlet port, an outlet port and an exhalation port in communication with a patient, an aerosol inhalation apparatus for delivering a medicament containing mist to the patient comprising:
- (a) a housing including:
- (i) an inlet chamber in communication with the outlet port of the ventilator and including an outlet;
- and
- (ii) a baffle chamber having an inlet in communication with said inlet chamber, an outlet in communication with the patient and baffle means for providing a circuitous fluid flow path through said baffle chamber;
- (b) nebulizing means for communication with said baffle chamber for nebulizing a fluid medication containing the medicament to produce a particulate laden spray and for introducing said particulate laden spray into said baffle chamber;
- (c) a first flow control means for controlling fluid flow outwardly of said outlet of said inlet chamber;
- and
- (d) valve means for controlling fluid flow between said outlet port of said ventilator and said baffle chamber and atmosphere.
