Description

[0001] This application is a divisional application of Chinese patent application CN202321848737.X, filed on July 14, 2023, entitled “A powder inhaler device and medicine box with auxiliary air inlet holes”. Technical Field

[0002] The present application relates to the technical field of powder inhalers, which are used for delivering powdered medicines, and more specifically to a powder inhaler device with an auxiliary air inlet hole. Background Art

[0003] In the field of powder inhaler technology, there are various types of powder inhalers. Existing powder inhalers can be divided into three categories:

[0004] The first category: a reservoir-type powder inhaler, which has a reservoir inside that can store a certain amount of powder. The powder inhaler also has a quantitative component that can separate a certain amount of powder from the reservoir at each brake, and then the separated powder is inhaled into the patient's body through the exhaust pipe. The disadvantages of this type of powder inhaler are: 1. The amount of powder delivered each time is unstable; 2. The sealing of this type of powder inhaler is poor, so the powder is easily damp in a relatively humid environment, affecting the expected effect; 3. During the separation of the powder in the reservoir, some powder will remain inside the powder inhaler, which will cause pollution to the powder inhaler and cause certain harm to the user.

[0005] The second category: multi-dose powder inhaler, the powder is independently stored in the blisters on the blister belt in advance, the blisters are evenly distributed on the blister belt, and the blister belt is installed on the rotating disk inside the powder inhaler; each time the powder inhaler is braked, a blister is opened, and the powder is inhaled into the patient through the discharge tube. This type of powder inhaler better ensures the sealing of the powder; its disadvantages: 1. Poor repeatability, there are differences in the delivery of the same powder inhaler to the patient before and after; 2. There will be residual powder inside the powder inhaler, which will cause pollution to the powder inhaler and cause certain harm to the user; 3. There will be powder residue in the blister, causing the performance of the powder to not achieve the expected effect;

[0006] The third category: single-dose powder inhaler, the powder is stored in a single capsule in advance, and the capsules are distributed on the capsule plate. When using, the patient first takes out the capsule from the capsule plate, and then puts the taken capsule into the capsule chamber of the powder inhaler. Press the button to puncture the capsule, and the powder is inhaled into the patient's body through the discharge tube.

[0007] However, the existing Chinese patent CN207640761 U discloses a powder medicine inhaler, which specifically discloses that a part of the air flows into the through hole through the ventilation slit, passes through the screen, and is then inhaled into the user's body through the mouthpiece. The airflow flowing into the through hole from the two ventilation slits merges into the main airflow flowing into the capsule chamber from the main air inlet at the bottom of the capsule chamber (the main air inlet at the bottom of the capsule chamber is the structure of the capsule chamber, that is, the air inlet of the capsule chamber in the figure), and interacts with each other to form turbulence, so that the powder medicine is fully dispersed under the drive of the turbulent gas and enters the user's body through the screen and the suction nozzle in turn. There are two disadvantages in designing the ventilation slits in this way: (1) Since it enters the capsule chamber together with the main air at the bottom, due to the long path, the turbulent force forming turbulence at the bottom will be relatively small, and the force for fully breaking up the powder will be relatively small; (2) Since the hole is actually opened at the connection between the carrier plate and the capsule chamber, since it is necessary to ensure the puncturing action of the puncturing mechanism and a certain amount of powder is required in the capsule chamber, the connection between the capsule chamber and the carrier plate requires a lot of force. The design of the opening will weaken the connection force at the connection between the carrier plate and the capsule chamber, which may cause certain operational obstacles. Utility Model Content
