A dry powder inhaler for pulmonary or nasal use, employing capsules (323) containing a dose of powder for inhalation, comprising two operating components and an optional cover. Air is drawn by the patient via a mouthpiece or nosepiece (303) which is in communication with the capsule (323) and travels via air paths through the device and through the capsule (323) thereby dispersing and entraining the dose of powder. The capsule (323) is cut by cutting means (350, 351) located on one of the components (300), in a manner which eliminates or minimizes capsule debris and minimizes powder leakage during use. The inhaler body (300) and capsule cutting blades (350, 351) comprise a single operating component and they may be manufactured in a single unitary step. The invention affords a very economical and simple device for the delivery of pulmonary medicines.一種肺用或鼻用之乾燥粉末吸入器，其利用包含一劑量吸入粉末的膠囊(323)，該吸入器包括兩個操作組件及一選用蓋。病人經由一口含件或鼻接件(303)而抽吸空氣，空氣係與膠囊(323)連通且經由空氣路徑行進通過裝置及通過膠囊(323)，從而分散並挾帶該劑量之粉末。以消除膠囊碎屑或使膠囊碎屑減至最少且在使用期間使粉末洩漏降至最低的方式，藉由位於該等組件(300)中之一者上之切割構件(350、351)來切割膠囊(323)。吸入器本體(300)及膠囊切割刀片(350、351)包括單一操作組件且其等可在單一整體步驟中製造。本發明提供一種用於遞送肺部藥物之相當經濟實惠且簡單的裝置。
