Abstract: A breath actuated metered dose inhaler may comprise a canister fire system configured to fire a medicament containing canister in response to patient inhalation. The canister fire system may comprise a pneumatic force holding unit and having a rest configuration in which a metering valve of the canister is in a refill configuration; a prepared configuration in which a canister actuation force is retained by the pneumatic force holding unit and the canister fire system is actuatable by patient inhalation induced airflow; and a fire configuration in which the metering valve is in a dose delivery position. When in the prepared configuration, the force retained by the pneumatic force holding unit may be reduced by less than about 6% over a period of 5 minutes, preferably less than about 3% over a period of 5 minutes.

Abstract: Disclosed herein is a quality control method for predicting premature degradation in mechanical properties of a series of moulded plastics components, the moulded plastics components being formed from a batch mixture comprising a cross-linkable polymer and a peroxide cross-linking agent. The method comprises selecting a subset of the series of moulded plastics components and obtaining a material specimen from the subset; and then extracting and measuring a residual peroxide content of the specimen. According to the invention, the measured residual peroxide content is representative of a probability of the pre-measuring mature age-related degradation in the entire series of moulded plastics components, and may therefore be compared against a threshold residual peroxide content to determine whether the entire series of components is of acceptable quality.
