摘要:
(1) Dosing device for generating a gas flow with an active substance finely dispersed in the latter. (2) The invention relates to a dosing device for generating a gas flow with an active substance (2) finely dispersed in the latter, as a result of an underpressure applied to a mouthpiece (6) of the dosing device, with a first gas flow channel (60, 61, 62, 63, 68), and with a dosing chamber (14) that can be fitted in the area of the first gas flow channel, and with a dosing chamber release mechanism which has a separating element (54, 76, 77) that can be moved between a closed position and an open position, wherein 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 the closed position, and 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 the open position, and with a slide guide element (53, 55) on which the separating element (54, 76, 77) is movable between the closed position and the open position and can be driven by the underpressure applied to the mouthpiece, and wherein the separating element and/or the slide guide element is provided at least in the sliding contact area with a slide element (100a, 100b, 101) that influences the sliding friction properties. This design of the separating element and/or of the slide guide element ensures that the separating element is reliably triggered after a suction stream is generated, such that the function of the dosing device can be more precisely reproduced and is more reliable.

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.

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.
摘要:
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.

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.

The present invention relates to mucoactive agents, such as heparin which are useful in the treatment of diseases where excess mucus is present in the respiratory tract, such as cystic fibrosis and chronic obstructive pulmonary disease. In particular, the invention relates to pharmaceutical compositions for administration by pulmonary inhalation. It also relates to methods for producing particles suitable for pulmonary inhalation, such as spray drying or jet milling.
