Medicament dispensing device, medicament magazine therefor and method of removing a medicament from a medicament chamber
摘要：
The invention relates to a medicament dispensing device, particularly a multi-dose powder inhaler, a medicament magazine thereof, and a method of removing a medicament from the medicament magazine as depicted in exemplary FIG. 1. 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.
摘要（中）：

本发明涉及药物分配装置，特别是多剂量粉末吸入器，其药剂盒，以及从药剂盒中去除药物的方法，如图示例所示。 吸入器具有接口（9）和连接到其上的空气通道（4），以及具有至少一个含有粉末状药物的药物室的药剂盒。 在空气通道中产生驱动电流，而可以通过驱动电流和在空气通道中形成的收缩来产生真空流（5'）。 产生真空流的空气通道的最窄部分连接到与控制开口（3）连通的去除开口（2），以便通过去除开口形成通过控制开口的排空电流。 在优选实施例中，包括控制开口，去除开口和填充开口的至少一个药剂室容纳在一体式药剂盒中。
