Abstract

Parts of a powdered medicine multi-dose administering device are assembled, powdered medicine is filled and assembly that is obtained is inspected all on an automatic production line to increase productivity while preventing the production of defective products. The powdered medicine multi-dose administering device is produced through automated steps of inserting a filter (12) in a filter-fitting portion (11a) of a container (10), inserting an inner cylinder (15) in the container body (10), filling the container with the powdered medicine through a ring-like opening between an opening in the upper part of the container and the inner cylinder, fitting an inner closure (19) to the container and to the inner cylinder, fitting a nozzle (20) to the container while coupling it to the inner cylinder, and inspecting the thus obtained assembly.

Description

technical field [0001] The present invention relates to an apparatus and a method for producing a multi-dose device for powdered medicaments (drugs), and in particular, to a device for producing powdered medicaments capable of administering any number of doses of powdered medicaments. Methods and apparatus for pharmaceutical devices. [0002] Powdered medicament multi-dose (multiple) administration devices contain the medicament in a container in an amount for multiple administrations, and meter and administer the medicament in an amount for each single dose. When producing and assembling this drug delivery device, the various procedures (steps) for assembling the various parts and for filling the device with a predetermined amount of powdered medicament sufficient for multiple administrations are all carried out automatically, and each device is assembled automatically. All checked after that. Accordingly, a method and an apparatus for the automated production of a multidos...
