  • Patent number: 9713683
    Abstract: The invention relates to a grid element for an inhaler which can be arranged in an air duct between a mouthpiece and a capsule chamber of the inhaler, it being possible for turbulence to be generated by means of the grid element in an airflow passing through the air duct. The grid element is characterized in that it comprises a preferably planar grid-type portion having a grid front side which points towards the capsule chamber and a grid rear side, at least one protruding element being arranged on the grid front side, by means of which a capsule that can be arranged in the capsule chamber can be loosely supported.

  • Publication number: 20170182255
    Abstract: An assembly for a drug delivery device (1) is proposed, comprising a housing (13) having a proximal end and a distal end, a dose member (23) which is displaceable in the proximal direction with respect to the housing for setting of a dose of a drug, a clutch member (28) which is displaced in the proximal direction with respect to the housing when setting the dose, and a stop member (30) configured to define a clutch stop position for the proximal displacement of the clutch member with respect to the housing, with the clutch member, when in the clutch stop position, being prevented from further displacement in the proximal direction with respect to the housing, wherein the clutch member and the dose member are configured to mechanically cooperate with one another when the clutch member is in the clutch stop position, thereby preventing further displacement of the dose member in the proximal direction with respect to the housing during setting of the dose. Furthermore, a drug delivery device (1) is proposed.

  • Patent number: 9205196
    Abstract: A method of preventing setting a dose which exceeds an amount of medication contained in a medication receptacle of a medication delivery device. The device comprising a piston rod comprising a second stop element, a drive device for moving the piston rod, and a dose setting member for setting a dose. The method comprising the steps of moving a dose limiting member which comprises a first stop element axially with respect to the piston rod during dose setting, and utilizing the first and second stop elements to stop an axial movement of the dose limiting member in the proximal direction when the first and second stop elements catch, limiting a movement of the dose setting member for increasing a set dose of medication. The dose limiting member and the piston rod only interact directly, when the first and second stop elements catch.

  • Publication number: 20090211576
    Abstract: Modifications of an inhaler and method of use thereof are described. In some embodiments, an inhaler may include one or more systems and/or methods that function to inhibit a child from accessing medicant from an inhaler. A system may function to inhibit a child from accessing an opening of an inhaler from which medicants are dispensed. In some embodiments, a system may inhibit a child from removing a cap for an inhaler. A system may function to inhibit a child from actuating an activation mechanism for an inhaler. A system may function to inhibit a user and/or a child from accidentally actuating an activation mechanism for an inhaler multiple times possibly resulting in an overdose. A system may function to inhibit an activation mechanism for an inhaler from actuating after the activation mechanism has been actuated a predetermined number of times.
