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 producing an inhalable aerosol of powdered medicament is disclosed. The inhaler includes an aerosolizing device having a chamber of substantially circular cross-section, inlet and outlet ports at opposite ends of the chamber for the flow of drug laden air through the chamber between said ports and, a bypass air inlet for the flow of clean air into the chamber. The bypass air inlet is configured so that air entering the chamber through said inlet forms a cyclone in the chamber that interacts with the drug laden air flowing between the inlet and outlet ports.

摘要: A passive inhaler (1) for delivery of a powder-form inhalation formulation from a blister strip (2) with a plurality of blister pockets (3) is proposed. The inhaler comprises an impaction element (31) onto which the air stream can impact together with entrained inhalation formulation for better deagglomeration. Alternatively, the inhaler comprises an oscillating and/or vibrating device (35) for better de-agglomeration of the inhalation formulation. Alternatively or additionally, the inhaler comprises one or two mixing means for generating swirls, preferably with opposite rotation directions.

摘要: An inhaler for producing an inhalable aerosol of a powdered medicament comprises a cyclone (1) with a tangential air inlet (3) and an axial air outlet (4). The cyclone (1) aerosolises and retains an aerosol of powdered medicament in an airflow circulating between the inlet (3) and the outlet (4). The cyclone (1) has an exit port (2) which is open to atmosphere. When the aerosol is to be inhaled, the pressure in the cyclone (1) is increased by increasing the airflow to the inlet (3) which causes the aerosol to discharge through the exit port (2). The inhaler has the advantage that the rate of discharge of the aerosol can be controlled independently of the rate of airflow required to aerosolise the medicament.

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 curved wall (12), a tangential inlet port (3) and an axial exit port (2). The radius R of the vortex chamber (1) decreases with angular extend θ. The reduction in effective cross-sectional area of the vortex chamber accelerates the gas flow between the inlet (3) and the outlet (2) to reduce deposition of the medicament.
