Background
Powder inhalers are known in the art, and there are various types of powder inhalers. Existing powder inhalers can be divided into three main categories:
the first type: a reservoir type powder inhaler having a reservoir for storing a dose of powder therein and a dosing member for separating the dose of powder from the reservoir on each actuation and then passing the separated powder through a discharge conduit for inhalation into a patient. The disadvantages of such powder inhalants: one, the amount of powder delivered per time is not stable; secondly, the sealing performance of the powder inhaler is poor, so that the powder is easily affected with moisture in a humid environment to influence the expected effect; and thirdly, in the process of separating the powder in the storage, partial powder is remained in the powder inhaler, so that the powder inhaler is polluted and certain harm is caused to a user.
The second type: a multi-dose powder inhaler, wherein the powder is separately stored in advance in blisters on a blister strip, the blisters are evenly distributed on the blister strip, and the blister strip is mounted on a rotating disc inside the powder inhaler; each actuation of the powder inhaler causes a blister to be opened and the powder to be inhaled into the patient through the discharge tube.
