Publication number: 20110094507Abstract: 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.Type: ApplicationFiled: December 29, 2008Publication date: April 28, 2011Applicants: Vectura Delivery Devices Limited, Boehringer Ingelheim GmbH, CD PatentsInventors: Herbert Wachtel, Quentin John Harmer, Matthew Neil Sarkar, Ivan Milivojevic

Publication number: 20090090362Abstract: A blister piercing element for puncturing the Hd of a blister containing a dose of medicament for inhalation by a user is disclosed. The piercing element comprising an outlet opening for the passage of medicament entrained in an airflow out of the blister and, a piercing head extending beyond and overhanging the opening that cuts a flap in a lid of a blister and pushes it away from the opening during insertion.Type: ApplicationFiled: April 13, 2006Publication date: April 9, 2009Applicant: Vectura Group PLCInventors: Quentin John Harmer, Roger William Clarke, Stephen William Eason, Andreas Mark Meliniotis

Publication number: 20080135441Abstract: A blister pack comprising a plurality of spaced blister cavities each configured to receive and store an individual dose of medicament for inhalation by a user is disclosed. The pack includes a foil layer and an outer polymer layer and each blister cavity, or a number of blister cavities, are separated from an adjacent blister cavity, or number of adjacent blister cavities, by a region of weakness formed by substantially removing or displacing a portion of the outer polymer layer from the foil layer.Type: ApplicationFiled: April 13, 2006Publication date: June 12, 2008Applicant: Vectura Group PLCInventors: Andreas Mark Meliniotis, Peter Alan Evans, Stephen William Eason, Quentin John Harmer

Publication number: 20080115785Abstract: 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.Type: ApplicationFiled: October 31, 2007Publication date: May 22, 2008Applicant: Vectura Delivery Devices LimitedInventors: Stephen William Eason, Quentin John Harmer, Matthew Neil Sarkar, John Pinon, Michael John Dunkley, Roger William Clarke, Stephen Henry Hill

Patent number: 7025056Abstract: 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 ?. 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.Type: GrantFiled: May 10, 2002Date of Patent: April 11, 2006Assignee: Vectura Delivery Devices LimitedInventors: Stephen William Eason, Raymond Anthony Edgson, Quentin John Harmer, Roger William Clarke

Patent number: 6948496Abstract: 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.Type: GrantFiled: July 20, 2001Date of Patent: September 27, 2005Assignee: Vectura, LimitedInventors: Stephen William Eason, Quentin John Harmer, Matthew Neil Sarkar
