Description

Capsule powder inhalation device

Technical Field

The present utility model relates to a capsule powder inhalation device for delivery for the treatment of respiratory diseases, such as: pharmaceutical agents in powder form for asthma and chronic obstructive pulmonary disease.

Background

There are various different kinds of capsule powder inhalers known in the art of capsule powder inhalers. Existing capsule 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 type powder inhaler, 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 601 of the powder inhaler, the capsules are pierced by pressing a button 300, and the powder is inhaled into the patient through a discharge tube. Disadvantages of existing such products: 1. the existing powder inhaler has poor reliability; for example: (1) during lancing, the lancing member disengages from the button 300 member; (2) the inability of button 300 to be normally depressed will render the powder inhaler inoperable; 2. the powder inhaler cannot be cleaned sufficiently and is easy to cause pollution; 3. the use is not humanized and the use is not convenient enough; the assembly process is complex, the reject ratio is high, and the manufacturing cost is high.

Existing patent numbers: CN1953779B, patent name inhalation device, discloses a spindle technique, but its drawbacks are: the manner in which the suction nozzle 200 is mated with the capsule housing 600 results in greater sloshing between the suction nozzle 200 and the capsule housing 600 and is prone to sloshing. Sloshing can affect the stability of the dry powder inhaler during use.
