Abstract

A new type of dry powder inhalation device, by providing a capsule type dry powder inhalation device with a plurality of capsule chambers (1a, 1b, 1c, 1d) arranged in parallel, providing a separate way to contain each active ingredient of the combination product The drug dispenser of the drug or its mixture has a simple structure and is easy to operate. In addition, each capsule chamber (1a, 1b, 1c, 1d) can adjust the parameters of the air inlet channel and the air outlet channel according to the properties of the powder of the drug or its composition, so as to set its proper mist particle distribution for each active ingredient.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to a novel dry powder inhalation device, in particular to a capsule type dry powder inhalation device. Background technique [0002] Dry powder inhalers (DPIs) are well known for their use in the treatment of bronchiectasis, typically driven by the patient's inspiratory flow, and aerodynamically disperse the drug into an inhalable powder. [0003] Capsule-type dry powder inhaler is a known dry powder inhaler, which includes a capsule chamber and an actuating part for opening the capsule chamber, and the opening of the capsule is mainly realized by shearing force, acupuncture or cutting, wherein Acupuncture is the most common opening mechanism, such as the capsule-type inhaler disclosed in US 8196578 B2. [0004] For capsule-type DPI with acupuncture mechanism, the powder contained in the capsule is released through the needle-punctured hole of the capsule during nebulization, and when ...
