阅读说明：本技术 单次剂量粉末吸入器 (Single dose powder inhaler ) 是由 克劳斯-迪特尔·贝勒 伯恩德·凯泽 于 2018-06-22 设计创作，主要内容包括：本发明提出一种用于鼻腔给药的单次剂量粉末吸入器(10),该单次剂量粉末吸入器具有扁平的吸入器壳体,该吸入器壳体由平面式的、沿连接平面(E)相互连接的两个壳体部分(1,2)构成。在这些壳体部分中成形有具有至少一个粉末容纳凹腔(11’)的药剂室(11)、进气开口(14)和由壁部(7)限制的气道,该气道从该进气开口(14)经由该药剂室(11)延伸至出口开口(12)。根据本发明,该进气开口(14)并不存在于与该出口开口(12)背离的侧面上,其中该气道提供气流经过该进气开口(14)相对于该出口开口(12)的方向改变。该气道的位于该药剂室(11)与该出口通道(12)之间的出口区段(13)具有多于一个弯曲部(6)。此外,在该出口开口(12)处成形有鼻形件(4),该鼻形件被设计为用于容纳到仅一个鼻孔中或用于容纳到两个鼻孔中。(The invention relates to a single dose powder inhaler (10) for nasal administration, comprising a flat inhaler housing which is formed from two housing parts (1, 2) which are connected to one another along a connecting plane (E) and are of planar design. A medicament chamber (11) with at least one powder-receiving recess (11'), an air inlet opening (14) and an air duct bounded by a wall (7) extending from the air inlet opening (14) to an outlet opening (12) via the medicament chamber (11) are formed in the housing parts. According to the invention, the air inlet opening (14) is not present on the side facing away from the outlet opening (12), wherein the air duct provides a change of direction of the air flow through the air inlet opening (14) relative to the outlet opening (12). The outlet section (13) of the airway between the medicament chamber (11) and the outlet channel (12) has more than one bend (6). Furthermore, a nose piece (4) is formed at the outlet opening (12), which nose piece is designed for receiving into only one nostril or for receiving into both nostrils.)
