A metering device activated by a user induced airstream for an inhalation of a medicinal substance. The device includes: a closure cap; a piston; a mouthpiece; and an annular chamber disposed upstream of the mouthpiece. A storage chamber stores the substance which can be moved out of the storage chamber when the closure cap is removed. A metering rod for removing the medicinal substance out of the storage chamber into an emptying-standby position. In the emptying-standby position, the metering chamber is closed by the piston. The piston is displaceable by airstream into an emptying-release position. In the emptying-release position, a metering chamber is released and the substance removed by the suction airstream. The metering device includes an outer cylinder which accommodates an inner cylinder.

Metering device for the inhalation of a pulverulent substance

The present disclosure concerns a counting mechanism for a drug delivery device, comprising a first counting member comprising an interaction element, a second counting member comprising engagement elements that are configured to engage with the interaction element of the first counting member, and a separating member, wherein the first counting member is moveable relative to the separating member between a first and a second relative position, and the separating member is configured to prevent an engagement of the interaction element with the engagement elements when the first counting member is in the second relative position with respect to the separating member. Further, the present disclosure concerns a drug delivery device comprising said counting mechanism.

Counting mechanism for a drug delivery device and drug delivery device

A dosing device generating a gas flow with an active substance finely dispersed, with a first gas flow channel and with a dosing chamber that can be fitted in the area of the first gas flow channel, and a dosing chamber release mechanism with a separating element. The first gas flow channel and/or a connection between the first gas flow channel and the dosing chamber is blocked when the separating element is in a closed position. The first gas flow channel and/or the connection between the first gas flow channel and the dosing chamber is freed when the separating element is in an open position. A slide guide element can be driven by the under-pressure applied to the mouthpiece. The separating element and/or the slide guide element is provided with a slide element that influences the sliding friction properties.

Inhaler

A dosing device can be activated by a vacuum air stream of a user for the inhalation of a powder substance, particularly medicine, which is arranged in a supply chamber and which can be brought out of the same into an open emptying-ready position by a dosing chamber of a dosing rod when the mouthpiece-closure cap is removed. In particular, in order to improve dispensing, the provision of two air paths, of which one serves to open and empty the dosing chamber, and/or the second air path penetrates directly into a ring chamber in order to mix with the air flow containing the substance.

A metering device can be activated by a suction airflow of a user for inhaling a powdery substance, in particular of medicinal type, which is arranged in a supply chamber and can be brought out of there into an apparent discharge standby position by removing a mouthpiece sealing cap by a metering chamber of a metering rod. The metering device provides piston-extensible tabs for sealing off the metering chamber, particularly for the facilitated opening of the metering chamber.
