Background
There are various different kinds of powder inhalers known in the art of powder inhalers. Existing powder inhalers can be divided into three main categories:
first category: a reservoir type powder inhaler having a reservoir for storing a dose of powder therein, and a member for metering the dose of powder to be separated from the reservoir at each braking, and the separated powder is sucked into a patient through an exhaust pipe. Disadvantages of such powder inhalants: 1. the amount of powder delivered per time is unstable; 2. such powder inhalers have poor sealability, so that the powder is easily wetted in a more humid environment, affecting the intended effect; 3. during the separation of the powder in the reservoir, a portion of the powder remains inside the powder inhaler, which can contaminate the powder inhaler and cause some harm to the user.
The second category: a multi-dose powder inhaler in which the powder is stored separately in advance in blisters on a blister strip, the blisters being evenly distributed on the blister strip, the blister strip being mounted on a rotating disc inside the powder inhaler; one blister is opened every time the powder inhaler is actuated, and powder is inhaled into the patient through the discharge tube. The powder inhaler ensures the tightness of the powder better; the defects are that: 1. poor reproducibility, differences in front and back delivery of the same powder inhaler into the patient; 2. the powder inhaler is internally provided with powder residues, which can pollute the powder inhaler and cause a certain harm to a user; 3. powder remains in the blister, so that the performance of the powder does not reach the expected effect;
third category: in a single dose powder inhaler, the powder is stored in a single capsule independently in advance, the capsules are distributed on a capsule plate, a patient firstly takes out the capsules from the capsule plate when using the powder inhaler, then puts the taken-out capsules into a capsule chamber of the powder inhaler, the capsules are pierced by pressing a button, and the powder is sucked into the patient through a discharge pipe.
However, the prior chinese patent CN209884953U discloses an improved capsule type dry powder inhaler, in particular a capsule type dry powder inhaler in which the inhalation device is in a closed state, and the cap latches and covers the mouthpiece in the closed position by the closing element; then, the operating mechanism is pressed to unlock the closing element from the plate, so that the latch is designed, when the operating mechanism is touched by mistake, the closing element is easy to unlock from the plate, and therefore, when the operating mechanism is touched lightly, the closing element cannot unlock from the plate, and a certain force is required to be given to the operating mechanism, so that the closing element can unlock from the plate.
