Zusammenfassung:To provide a single-dose powder inhalator which is easy and cost-effective to produce, easy to use, and is improved with regard to deagglomeration of the contained powder and completeness of powder emptying.SOLUTION: The single-dose powder inhalator comprises an inhalator housing 1 having a housing part 1, in which at least one medicament chamber 11 with a dose of a powdered medicament is formed. The inhalator housing 1 has an outlet opening 13' and an outlet duct 13 which extends from the medicament chamber 11 to the outlet opening 13'. The outlet duct 13 is advantageously formed in the housing part 1. Also formed in the housing part 1 are an air inlet opening 12', on a side of the medicament chamber 11 that is facing away from the outlet opening 13', and an inlet channel 12. The inlet channel 12 extends from the air inlet opening 12' to the medicament chamber 11.SELECTED DRAWING: Figure 1 【課題】製造が容易かつ費用効率が高く、使用が容易であり、収容される粉末の解凝集と粉末を完全に空にすることとに関して改善された単回投与粉末吸入器を提供する。【解決手段】粉末薬剤の投与量を有する少なくとも1つの薬剤チャンバ11が形成されているハウジング部1を有する吸入器ハウジング1からなり、吸入器ハウジング1は、出口開口部13'と、薬剤チャンバ11から出口開口部13'まで延在する出口ダクト13とを有する。出口ダクト13は、有利にはハウジング部1に形成される。ハウジング部1にはまた、出口開口部13'から離れる方向に面している薬剤チャンバ11の側における空気入口開口部12'と、入口ダクト12とが形成され、入口ダクト12は空気入口開口部12'から薬剤チャンバ11まで延在する。【選択図】図1
