Publication number: 20090308388Abstract: A dry powder inhaler (101) comprises an inhaler body (110), including an air passageway, and a medicament container (120). The medicament container (120) holds a dose of medicament and is provided with at least one dispensing aperture (123) through which the medicament may be drawn from the medicament container (120). The medicament container (120) is displaceable from a first position, in which the dispensing aperture (123) is occluded, to a second position, in which the dispensing aperture (123) is open and air is able to flow along the air passageway. When the medicament container (120) is in the first position, the air passageway is occluded by the medicament container (120).Type: ApplicationFiled: June 26, 2007Publication date: December 17, 2009Inventor: Brindra Paul Singh Chawla

Publication number: 20090263408Abstract: A medicament package (10,30) comprises a vessel (12,32) adapted to hold a quantity of a liquid vehicle. The vessel (12,32) has an opening formed therein, to which opening is bonded a deformable enclosure (18,38). A medicament container (20) that contains a unit dose of a medicament is received within the enclosure (18,38), such that by deformation of the enclosure (18,38) the container(20) may be dislodged from the enclosure (18,38) into the vessel (12,32), whereby the medicament may escape from the container (20) and mix with the liquid vehicle. The medicament contained within the medicament container (20) is most preferably in admixture with sodium chloride.Type: ApplicationFiled: June 29, 2009Publication date: October 22, 2009Inventor: BRINDRA PAUL SINGH CHAWLA

Patent number: 7562769Abstract: A medicament package comprises a vessel adapted to hold a quantity of a liquid vehicle. The vessel has an opening formed therein. The opening engages a deformable enclosure which receives a medicament container that contains a unit dose of a medicament. The entire medicament package is sterile and is arranged such that by deformation of the enclosure the container may be dislodged from the enclosure into the vessel whereby the medicament may escape from the container and mix with the liquid vehicle. The medicament container is formed with one or more dispensing apertures through which the medicament may exit the container and/or liquid can enter the container. The medicament container may be formed as two or more components, the integrity of the container being maintained by its engagement with the enclosure and that integrity being lost once the container is released from the enclosure.Type: GrantFiled: March 11, 2004Date of Patent: July 21, 2009Assignee: Brintech International LimitedInventor: Brindra Paul Singh Chawla
