Abstract: An auto-reset dose release firing system (101) and a method of using same. The system can include an a stored energy device (109); a first plunger (103) movable between first, second, and third positions, the first plunger configured to be operatively coupled to a medicament canister (51); and a second plunger (104) movable between first and second positions; the first and second plunger being movable with respect to one another and shaped to define an evacuable chamber (185) therebetween. The first plunger and the second plunger can move together from their respective first positions to their respective second positions, due to a reduced pressure in the chamber, to cause a dose release valve (54) to fire. After firing, air can be allowed to move into the chamber to allow the first plunger to move with respect to the second plunger to its third position to allow the dose release valve to reset.

Abstract: A dose counter for use in connection with a device adapted for metered dispensing of a medication is described. The dose counter has a first count indicator that has a first indicia bearing surface, with the first count indicator being rotatable about a first axis. The dose counter also has a second count indicator that has a second indicia bearing surface, with the second count indicator being rotatable about a second axis. The second axis is disposed at an obtuse angle with respect to the first axis, and the first and second indicia bearing surfaces align at a common viewing area to collectively present at least a portion of a medication dosage count.

Abstract: The present disclosure relates to a dose indicator for a pressure-actuated metered dose inhaler (pMDI) device. In an embodiment, the dose indicator comprises a chassis element having a viewing portion, a display element located within the chassis element, a resilient deformable element, and an indexing element having an axis, translation of the indexing element along its axis from a first position to a second position causing deformation of the resilient deformable element in the same direction as translation of the indexing element resulting in generally greater displacement of portions of the resilient deformable element nearer to the axis relative to portions thereof further from the axis, the displacement of the portions of the resilient deformable element in the same direction as translation of the indexing element inducing indexing of the display element from a current position to a subsequent position relative to the viewing portion of the chassis element

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.
