    摘要： An inhaler for producing an inhalable aerosol of a powdered medicament includes an aerosolizing device in the form of a vortex chamber 1. The vortex chamber 1 has a tangential inlet port 3 and an axial port 2. The ratio of the diameter of the vortex chamber 1 to the diameter of the exit port 2 is between 4 and 12. The length of the exit port 2 is less than its diameter. The cross-section of the inlet port 3 is rectangular and is defined at the bottom and at the radially outermost edge by the walls of the vortex chamber 1. The cross-sectional area of the inlet conduit 7, which supplies the medicament in a gas flow to the inlet port 3, decreases in the direction towards the vortex chamber 1. The inlet conduit 7 may be curved. The inhaler is capable of repeatably producing an aerosol of a medicament with a high proportion of particles in the range 1 to 3 microns, while using a 20 relatively small amount of energy.

    摘要： An Inhaler for delivering an aerosolised dose of a powdered drug for inhalation by a user is disclosed. The inhaler comprises a drug entreinment device to a receive a package having a piercable lid containing a dose to be delivered, the device including a drug outlet tube terminating with a primary piercing element to pierce an opening in said lid when a package is located in the inhaler, a secondary piercing member to pierce a plurality of peripheral openings in said lid and, an airflow path to enable the supply of a charge of gas into the package via said peripheral openings to scour the interior of a pierced package such that all or substantially all of the dose is entrained in the gas and flows out of the package via the drug outlet tube. A medicament pack is also disclosed.
