Abstract
A drug transfer system is adapted to transfer a powdered drug into a patient via inhalation. The drug transfer system includes a drug container or packet that removably inserts into an inhaler device. As the patient inhales from the inhaler device, the drug flows from the container, through the inhaler device, and into the patient's respiratory system. The system is adapted for ease of use without requiring the user to perform any cumbersome manipulations of the drug packet during insertion into the inhaler or during inhalation of the drug.
Claims26
A drug dispenser package, comprising:
- a blister containing a powder formed of a plurality of particles, the blister including:
- (a) a vertex;
- (b) a first limb extending outwardly from the vertex, wherein an air entry port is positioned at an end of the first limb opposite the vertex, the air entry port providing an entryway for air to flow into the blister;
- (c) a second limb extending outwardly from the vertex, wherein an air exit port is positioned at an end of the second limb opposite the vertex, the air exit port providing an exitway for air to flow out of the blister with at least a portion of the powdered drug;
- an aspiration hole separate from the air entry port and air exit port, the aspiration hole having a size that is less than the minimum size of all the particles of the powder such that the aspiration hole is sufficiently large to permit airflow into the blister but too small to permit a particle of the powder to pass through the aspiration hole;
- and
- wherein the blister comprises side walls that extend outwardly from a base at an angle of 90 degrees relative to the base
- an inhaler that removably docks with the blister, the inhaler adapted to transfer drug from the blister into a patient upon inhalation of the patient from the inhaler, the inhaler including a mouthpiece that inserts into the patient's mouth, a cap removably attached to the mouthpiece and sized and shaped to provide a storage space for the blister, and a blister interface that is removably attached to the mouthpiece and the cap and adapted to receive the blister in a manner that positions the blister in the inhaler in a proper orientation for use, wherein the blister interface includes an airflow hole that aligns with the air exit port of the second limb when the blister is positioned in the blister interface.
