摘要:
A medicament dispensing device, a medicament magazine thereof, and a method of removing a medicament from the medicament magazine. The inhaler has a mouthpiece (9) and an air channel (4) connected thereto, as well as a medicament magazine with at least one medicament chamber containing a powdered medicament. A drive current is produced in the air channel, while a vacuum flow (5′) can be produced by the drive current and a constriction formed in the air channel. This narrowest part of the air channel that produces the vacuum flow is connected to a removal opening (2) which communicates with a control opening (3), in order to form an emptying current through the control opening via the removal opening. In a preferred embodiment the at least one medicament chamber including the control opening, the removal opening and a fill opening are housing in the one-piece medicament magazine.

An inhaler for inhaling powdered medicament from capsules is described. Once the capsule has been placed in the capsule holder (3), the patient can press an actuating member (8), which interacts with at least one pin (9) adapted to be pushed into the capsule holder (3), causing the medicament to be released. In a preferred embodiment, the actuating member (8) is constructed as a multi-functional actuating member (8a) wherein, in a first functional position, the closure element (6) can be disengaged from the lower part (1) in order to pivot the cover (5), and wherein, in a second functional position, the mouthpiece (4) engaging with the plate (2) can be released from the plate (2) in such a way that the mouthpiece (4) can be pivoted away from the lower part (1).

The invention relates to an apparatus for nebulising preferably powdered medicinal formulations, the nebulisation being assisted by propellant. According to the invention, the propellant is supplied in pulsed form to the powder cavity (1) containing the formulation, which is attached to the nozzle (3) from which the aerosol is emitted. The apparatus according to the invention provides an increase in the fraction of pulmonary particles in the aerosol leaving the nozzle (3).

The present invention relates to capsules for housing pharmaceutical preparations for powder inhalers with increased medicinal product safety and capsules for pharmaceutical preparations for powder inhalers with improved adaption to use in powder inhalers. The capsules consist of non-water-soluble, hydrophobic plastics, which themselves do not substantially influence the pharmaceutical quality of the contents, but improve the usability of the filled capsules in respect of their operation, the period of use and/or the geographical location of their use and are advantageous in various steps from manufacture to use.
摘要:
The invention is a medicament magazine having at least one medicament chamber for use in a powder inhaler, wherein the magazine is formed from two foil strips applied to one another and the at least one medicament chamber is formed between the foil strips as depicted in exemplary FIGS. 1a and 1b. The medicament chambers have an internal structure (3) which comprises in its interior a space for receiving a powdered medicament and stabilizes this inner space against external mechanical influences. In another embodiment in which the internal structure preferably also has a stabilizing function, the structure has means for opening one foil strip. In addition, the medicament chamber contains a retaining device which holds the internal structure on the medicament magazine after the medicament chamber has been opened.
