Description

Powder suction device
Technical Field
The invention relates to the field of medical instruments, in particular to a powder inhalation device.
Background
Known in the art of powder inhalers are various types of powder inhalers, and the existing powder inhalers can be classified 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; 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. The powder inhaler better ensures the tightness of the powder; the disadvantages are as follows: firstly, the repeatability is poor, and the difference exists between the front and back delivery of the same powder inhaler to a patient; secondly, the powder inhalator is polluted due to the residual medicine powder inside the powder inhalator, so that certain harm is caused to a user; thirdly, powder residue exists in the bubble cap, so that the performance of the powder does not achieve the expected effect;
the third type is a single-dose powder inhaler, powder is independently stored in a single capsule in advance, the capsule is distributed on a capsule plate, when a patient uses the powder inhaler, the capsule is taken out from the capsule plate firstly, then the taken-out capsule is placed in a capsule chamber of the powder inhaler, the capsule is punctured by pressing a button 3, and the powder is inhaled into the body of the patient through a discharge pipe.
