Abstract
An inhalation device for administering an aerosolized medication includes an incentive spirometer and a medication inhalation chamber having receptacle means adapted to receive a metered dose inhaler for misting aerosolized medication in the chamber. Further provided is a method for administering an aerosolized medication which involves training a subject to breath using the inhalation device and administration of the medication from the device.
Claims25
An inhalation device for administering to a subject an aerosolized medication, comprising:
- an air flow spirometer for indicating to the subject, the subject's inhalation performance;
- a medication inhalation chamber connected at a first chamber location to said indicating means;
- a mouthpiece connected to said chamber at a chamber location spaced from said first location;
- and
- means for connecting a metered dose inhaler to said chamber whereby to receive into said chamber a metered dose of aerosolized medication at a location sufficiently spaced from said mouthpiece connection so as to enable the chamber to hold aerosolized medication in suspension while baffling larger particles thereof to decrease the amount thereof in said suspension, air from said spirometer flowing through said chamber whereby to deliver smaller therapeutic aerosolized medication through said mouthpiece to said subject in conjunction with operation of said spirometer.
An inhalation device for administering an aerosolized medication, comprising:
- an incentive spirometer adapted for one-way inspiratory flow, said spirometer having an outlet and a flow regulator;
- an elongated hose having a mouthpiece at a downstream end and coupling means at an upstream end;
- and
- a medication inhalation chamber having a substantially cylindrical shape, said chamber having receptacle means opening into said chamber and adapted to receive a metered dose inhaler cannister for misting aerosolized medication into said medication inhalation chamber, said chamber placed in line between said outlet and said coupling means.
A method for administering an aerosolized medication to a subject comprising the steps of:
- providing an inhalation device for administering aerosolized medication, said device comprising:
- an air flow spirometer for indicating to the subject, the subject's inhalation performance,
- a medication inhalation chamber connected at a first chamber location to said indicating means,
- a mouthpiece connected to said chamber at a chamber location spaced from said first location, and
- means for connecting a metered dose inhaler to said chamber whereby to receive into said chamber a metered dose of aerosolized medication at a location sufficiently spaced from said mouthpiece connection so as to enable the chamber to hold aerosolized medication in suspension while baffling larger particles thereof to decrease the amount thereof in suspension, air from said spirometer flowing through said chamber whereby to deliver smaller therapeutic aerosolized medication through said mouthpiece to said subject in conjunction with operation of said spirometer:
- training said subject to inspire in such a way as to optimize subsequent delivery of aerosolized medication;
- delivering into said receiving means of said chamber a metered dose of aerosolized medication;
- and
- having said subject inspire medication to achieve therapeutic deposition of medication in a subject's airways.
