  • Flow governors for use in medicinal inhalers
    Patent number: 11376378
    Abstract: A flow governor for use in a medicinal inhaler. The flow governor can include (i) a tubular element that defines at least a portion of an air flow path, the tubular element comprising at least one flexible wall configured to flex inwardly in response to an air flow in the air flow path; and (ii) an internal support structure, located within the tubular element and configured to preserve at least a predetermined cross-sectional area of the air flow path within the tubular element when the at least one flexible wall of the tubular element flexes inwardly.

  • Flow governor assemblies for use in medicinal inhalers
    Patent number: 11376379
    Abstract: A flow governor assembly for use with a medicinal inhaler. The assembly can include a housing that defines an air flow path; a flow governor positioned in the air flow path to govern air flow in the air flow path to a target governing volumetric flow rate; and a constriction in the air flow path. The flow governor can be configured to provide a variable, or dynamic, resistance to air flow in the air flow path as a function of air pressure drop between an inlet and an outlet of the flow governor. The constriction can be configured to provide a fixed, or static, resistance to air flow in the air flow path.

  • MEDICINAL INHALERS
    Publication number: 20190001085
    Abstract: A medicinal inhaler. The inhaler can include a housing, and an air flow path defined by at least partially the housing and including an air inlet and an air outlet. The inhaler can further include a flow governor and a breath-actuated dose release firing system. The flow governor can be positioned in the air flow path between the air inlet and the air outlet to govern air flow in the air flow path to a governing volumetric flow rate. The breath-actuated dose release firing system can be located in the housing and can be configured to release a dose of medicament at a firing volumetric flow rate less than the governing volumetric flow rate.
