摘要： A unit dose dry powder inhaler includes a chamber housing containing a powder dispersion chamber. A chamber tube extends from the dispersion chamber into the mouthpiece. A cover or cup is rotatably attached to the chamber housing. A dose of a dry powder is contained at a powder location in the chamber housing. An air passageway leading from the powder location to the dispersion chamber is closed off by the cover. When the cover is rotated to an open position, the air passageway is opened. The user inhales on the mouthpiece drawing air through the powder location, the air passageway, the dispersion chamber and the chamber tube, through the mouthpiece and into the users lungs. The unit dose of dry powder is stored directly in, or is part of, the inhaler.

摘要： A unit dose dry powder inhaler has a dose unit within an inhaler housing. As the dose unit is pushed into the inhaler housing, a container on the dose unit is opened, releasing a pharmaceutical powder into the housing. The user inhales on a mouthpiece, drawing the powder and air into a dispersion chamber. The powder disperses in air, and the powder/air mixture is inhaled. The inhaler is inexpensive, compact, and simple to use.
摘要翻译： 单位剂量干粉吸入器在吸入器外壳内具有剂量单位。 当剂量单元被推入吸入器壳体中时，打开剂量单元上的容器，将药物粉末释放到壳体中。 使用者吸入吹嘴，将粉末和空气吸入分散室。 粉末分散在空气中，并且粉末/空气混合物被吸入。 吸入器便宜，紧凑，使用简单。

摘要： A unit dose dry powder inhaler has a dispersion chamber, optionally including one or more beads. A blister is supported adjacent to the dispersion chamber. A mouthpiece cover is removable from a mouthpiece, with movement of the mouthpiece cover causing the blister to open. An air flow path extends past or under the blister and into the dispersion chamber. As a result, the blister remains sealed until the inhaler is ready for use. The blister is then automatically opened when the mouthpiece cover is removed from the mouthpiece. Pharmaceutical dry powder is released from the blister and entrained in air flow through the inhaler, when the user inhales on the mouthpiece. The powder is dispersed in air within the dispersion chamber.
