Abstract

Un inhalador de dosis medidas para usar con un recipiente en aerosol presurizado que es preferentemente activado con la respiración.Se aplica en la válvula interna de aerosol una carga previa (80) de la cantidad suficiente para resultar en la liberación de la dosis , pero esto es impedido por la aplicación de una fuerza de resistencia neumática (130). El inhalador comprende un aparato de liberación (110) que, al ser activado, libera la fuerza de resistencia y permite que la carga previa active la válvula de aerosol (135). Se libera entonces una dosis medida de medicamento para que el paciente la inhale. La fuerza de resistencia neumática es creada por una región de presión negativa definida en parte por un diafragma. El diafragma incluye un disco central de un primer material de rigidez relativamente alta y un anillo periférico, unidos por un flexor de un segundo material de rigidez relativamente baja.A metered dose inhaler for use with a pressurized aerosol canister that is preferably activated with breathing. A preload (80) of sufficient amount is applied to the internal aerosol valve to result in dose release, but this it is prevented by the application of a pneumatic resistance force (130). The inhaler comprises a release apparatus (110) which, when activated, releases the resistance force and allows the preload to activate the aerosol valve (135). A measured dose of medication is then released for the patient to inhale. The pneumatic resistance force is created by a region of negative pressure defined in part by a diaphragm. The diaphragm includes a central disc of a first material of relatively high stiffness and a peripheral ring, joined by a flexor of a second material of relatively low stiffness.
