Medicament dispensing device with a multimaterial diaphragm bounding a pneumatic force chamber
Issued: December 29, 2009
Inventor(s): Holroyd; Michael
Assignee(s): Norton Healthcare Limited
A metered dose inhaler for use with a pressurized aerosol container which is preferably breath-actuated. A preload is applied to the internal aerosol valve by an amount sufficient to result in a dose release, but this is prevented by the application of a pneumatic resisting force. The inhaler comprises a release device which, upon actuation, releases the resisting force and allows the preload to actuate the aerosol valve. A metered dose of medicament is then released for inhalation by the patient. The pneumatic resisting force is established by a negative pressure region defined in part by a diaphragm. The diaphragm includes a central disk of a first, relatively high stiffness material and a peripheral ring, coupled by a flexure of a second, relatively low stiffness material.

An inhaler, such as a breath-actuated metered-dose inhaler, for delivering medicament to a patient. The inhaler includes a housing for holding the medicament and having an air inlet and a medicament delivery port which together define an air flow path into which the medicament is dispensed. The air inlet includes an array of elongate apertures formed in the housing, the long sides of adjacent apertures facing each other. Each aperture is provided with a respective different opening in an outer surface of the housing. The opening of each aperture extends in two different planes such that, if at least a part of the opening is covered in one of the two different planes during inhalation by the patient, a void space is created between the cover and the aperture so as to provide an air flow path through the void space to the at least one aperture.
