摘要:
An inhaler for delivery of a powder-form inhalation formulation from a blister strip with a plurality of blister pockets containing the inhalation formulation in doses. The inhaler comprises a metallic piercing member with two piercing elements extending parallel to each other and inclined to the lid of a blister pocket to be punctured. To operate the inhaler, an air stream of ambient air can be sucked or delivered in order to discharge the respective dose from an opened blister pocket and to deliver the dose with the ambient air as an aerosol cloud.

An inhaler is proposed having an insertable container and a monitoring device for counting uses of the inhaler. The monitoring device is arranged in a detachable housing part or fitted onto a mouthpiece of the inhaler. A supply air current is detected by means of a pressure sensor. A position sensor may further be provided.

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).
摘要:
A passive inhaler for delivery of a powder-form inhalation formulation from a blister strip with a plurality of blister pockets is proposed. The inhaler comprises a metallic piercing member with two piercing elements extending at least essentially in V-shape away from each other and being at least essentially flat. A contact member is arranged between the piercing elements to contact a lid of a blister pocket in an area between separate openings formed by the piercing elements in the lid,

The invention relates to a powder inhaler with at least one specially sharpened needle, to ensure the precise piercing or cutting open of capsules and hence the optimum delivery of powdered medicament compositions, medicament formulations or medicament mixtures, as well as ensuring that little effort is needed to perforate or cut open the capsule.
摘要:
A medicine dispensation device, in particular a multi-dose powder inhalator, for the dispensing of individual doses of medicine that has a number of medicine chambers contained in a medicine magazine shaped like a continuous loop. The medicine chambers form groups in such a manner that a mouthpiece reaches the different groups by an essentially complete rotation of the medicine magazine. This enables several medicine chambers—typically one, two or three—to be situated between two successive intake positions, which allows for a high density of medicine chambers and thus creates an inhalation device, which can be handled comfortably even when containing a great number of individual doses.

The invention relates to a medicament magazine with a plurality of doses of medicament, wherein the magazine is formed from a single foil strip in which pouches (2) for holding a medicament are formed as depicted in exemplary FIG. 1. The foil strip comprises for transporting the strip openings (4) on at least one side for the engagement of transporting pins. The foil strip has a certain width in the region of the pouches, which is less than the width of the foil in other regions, and the openings are arranged in this broader part of the foil strip. The invention also relates to a method and a device for opening a medicament magazine of this kind, the device preferably being constructed as a segmented wheel.
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.
