Patent number: 11957832Abstract: 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.Type: GrantFiled: October 2, 2020Date of Patent: April 16, 2024Assignee: Norton (Waterford) LimitedInventors: Declan Walsh, Paul Prendergast, Daniel Buck, Trevor Kent, Niall Thompson

Publication number: 20220323699Abstract: An inhaler includes a main body having a canister housing, a medicament canister retained in a central outlet port of the canister housing, and a dose counter having an actuation member for operation by movement of the medicament canister. The canister housing has an inner wall, and a first inner wall canister support formation extending inwardly from a main surface of the inner wall. The canister housing has a longitudinal axis X which passes through the center of the central outlet port. The first inner wall canister support formation, the actuation member, and the central outlet port lie in a common plane coincident with the longitudinal axis X such that the first inner wall canister support formation protects against unwanted actuation of the dose counter by reducing rocking of the medicament canister relative to the main body of the inhaler.Type: ApplicationFiled: June 29, 2022Publication date: October 13, 2022Inventors: Declan Walsh, Derek Fenlon, Simon Kaar, Jan Geert Hazenberg, Daniel Buck, Paul Clancy, Robert Charles Uschold, Jeffrey A.

Publication number: 20210302407Abstract: 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.Type: ApplicationFiled: January 30, 2018Publication date: September 30, 2021Applicant: Norton (Waterford) LimitedInventors: Daniel Buck, Declan Walsh, Paul Prendergast
