Abstract
An apparatus for use in conjunction with a metered dose inhaler which includes a novel valve system to aid in the delivery of aerosolized medicament to a subject. The apparatus also includes a novel rotational flow generator to aid in the useable delivery of said medication and avoid its loss either in the apparatus or by non-useful delivery to said subject.
Claims50
An apparatus for aerosol medication delivery, comprising:
- a holding chamber having a first and second ends, the first end being adapted to accept a source of aerosol medicament;
- and
- a mouthpiece member provided at the second end of the holding chamber, for delivering aerosol medicament to a subject, the mouthpiece member comprising:
- a housing defining a passage through which aerosol medicament can be supplied to a subject and comprising a sidewall in which an opening is formed that opens to the outside of the housing;
- and
- a one-piece valve member comprising a first valve element in the passage that permits delivery of aerosol to a subject during inhalation and blocks the passage during exhalation and a second valve element that blocks the opening in the sidewall of the housing during inhalation and is movable away from the opening to permit the flow of air to the outside of the housing from the passage during exhalation.
A mouthpiece member for aerosol medicament delivery, having first and second ends, the first end being adapted to accept a source of aerosol medicament and the second end being adapted for delivering aerosol medicament to a subject, the mouthpiece member comprising:
- a housing defining a passage through which aerosol medicament can be supplied to a subject and comprising a sidewall in which an opening is formed;
- and
- a one-piece valve member comprising a first valve element that permits delivery of aerosol to a subject during inhalation and blocks the passage during exhalation and a second valve element that blocks the opening in the sidewall of the housing during inhalation and is movable away form the opening to permit the flow of air to the outside of the housing from the passage during exhalation.
An apparatus for aerosol medication delivery, comprising:
- a mouthpiece member for delivering aerosol medicament to a subject,
- a holding chamber having first and second ends, the mouthpiece member being disposed at the second end of the chamber and
- a receptacle member being disposed at the first end of the chamber, the receptacle member comprising:
- an opening adapted to accept a source of aerosol medicament,
- a vent permitting fluid communication for the entry of outside air into the holding chamber, and
- a means for imparting a rotational flow to the outside air entering the holding chamber.
