  • Patent number: 11040157
    Abstract: A drive mechanism for a medicinal inhaler, the inhaler comprising: a patient port; a canister actuable by the drive mechanism to deliver a dose of medicament to the patient port, the drive mechanism comprising: a follower which moves between a first position in which the mechanism is primed for use and a second position in which the follower engages the canister to deliver a dose of medicament to the patient port, the follower being carried on a rocker plate which pivots as the follower moves between its first and second position, wherein the rocker plate engages a switch when the follower is in its second position to indicate that a dose of medicament has been delivered to the patient port.

  • Patent number: 10335563
    Abstract: An actuator for an inhaler, in particular a nasal actuator, is disclosed, the actuator comprising a body, a stem post and fixing means for fixing the stem post in the body. The body comprises a delivery passage for delivery of a medicament and a canister opening for insertion of a canister having a metering valve with a valve stem. The stem post comprises a stem socket for receiving the valve stem of a canister and comprises an orifice for discharging a medicament to the delivery passage. The stem post and body are adapted so they cooperate to define a transition chamber when the stem post is fixed in the body. Also disclosed is a method of forming an component for an actuator for an inhaler, and a method of assembling an actuator for an inhaler by inserting the stem post through the canister opening and into the body thereby.

  • Publication number: 20170007788
    Abstract: The present invention provides an actuator (10) for a nasal inhaler (5). The actuator comprises an elongate body (15) comprising a canister opening (11), a nose piece (30) adapted for nasal delivery of a medicament, and fixing means for fixing the nose piece to the elongate body (15). The nose piece is fixable to the body at an acute angle to the elongate body. A first portion of the nose piece defines an outlet (25) for discharging a medicament from the actuator. The nose piece is adapted and the elongate body is adapted so that when the nose piece is fixed to the elongate body, the nose piece and elongate body cooperate to define a fluid communication pathway from the canister opening to the outlet. The present invention is also directed to an inhaler comprising an actuator as discussed, and a canister.

  • Patent number: 9089661
    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.

  • Patent number: 8814009
    Abstract: An aerosol metering valve comprising: (a) a valve stem movable between a rest position and a firing position comprising: a body portion comprising a circumferential sealing surface (b) a valve body comprising: a body wall, and an internal chamber defined at least in part by the body wall; and (c) a metering gasket having an inner periphery defining an aperture, being disposed near the most interior end of the internal chamber and being configured to be able to form a transient, substantially fluid-tight face seal against the circumferential sealing surface of the valve stem, where at the rest position of the valve stem, the body portion of the valve stem is located within the internal chamber and as the valve stem is moved from its rest position towards its firing position the circumferential sealing surface of the valve stem contacts the metering gasket to form a face seal thereby closing a metering chamber and thereafter further movement of the valve stem towards its firing position causes the metering gask

  • Patent number: 8517019
    Abstract: This application discloses a dose counter device of the type for use on an aerosol dispensing assembly having an aerosol container and an actuator. The dose counter device is used for indicating the release of a dose of aerosol medication caused by the application of a force, in an axial direction, on the aerosol dispensing assembly. The dose counter device has a cap, a slider and a first counter ring. The cap is moved in a first direction along an axis of the container, which causes movement of the slider in a first linear direction laterally, relative to the axis of the container, as a function of the movement of the cap in the first direction. The first counter ring is rotated through a first arc in a first circumferential direction about the axis of the container, as a function of the movement of the slider in the first linear direction.
