[0002] Oral administration route is the most common administration route of most drugs and is the preferred administration route of patients. However, drugs using this route need to face the degradation of the gastrointestinal tract and the liver first-pass effect, so that the dose at the time of administration is large and the drug onset rate is slow. Subcutaneous injection administration inevitably needs to damage the patient's skin, which reduces the patient's medication compliance to some extent. The human alveolar wall is thin and densely covered with a large number of capillaries, drugs can quickly penetrate the alveolar mucosa and directly enter the blood circulation, the dose is small, and the effect is fast, which is the best treatment for lung diseases such as asthma and chronic obstructive pulmonary disease, and has good market prospects.

[0003] However, the mature devices on the market that use medicine powder capsules to complete pulmonary administration are all structures that assist single capsule administration. When patients need to use multiple doses or compound drugs at the same time, the device has a high repeatability. In the double capsule type medicine powder inhalation device developed and designed by some companies, the push button assembly that pierces the capsule is arranged on both sides of the capsule compartment. During use, the patient needs to press the push buttons on both sides at the same time, and there is no fixed end support, so that the capsules on both ends are not subjected to equal force, which may cause the capsules not to be completely pierced.

DETAILED DESCRIPTION

[0028] The following description is provided to enable any person skilled in the art to practice the present application. The preferred embodiments in the following description are only examples of the present application, and other obvious modifications can be made by those skilled in the art.

[0029] Figures 1 to 6 A preferred embodiment of the double-capsule type powder inhalation device of the present application is shown, which includes: a top cover shell 1, a mouthpiece assembly 2, a capsule compartment plate 3, a base shell 4, and a push button assembly 5. Among them:

[0030] like Figures 1-2 As shown, the top cover shell 1 and the suction nozzle assembly 2 are coaxially fixed to the base shell 4. The top cover shell 1 is fitted onto the suction nozzle assembly 2. One end of each of the three is fixed, and the other end can be rotated open sequentially along an arc. The capsule compartment plate 3 and the base shell 4 are fixed by snap-fit. The push button assembly 5 is located on the side where the suction nozzle assembly 2 and the top cover shell 1 can be opened. The push button assembly 5 is laterally connected to the capsule compartment plate 3. The push button assembly 5 includes an elastic member 51, needles 52, and a push button shell 53. The elastic member 51 is sandwiched between the push button shell 53 and the capsule compartment plate 3, providing the push button assembly 5 with a rebound force away from the capsule compartment plate 3. The elastic member 51 is preferably a compression spring. On the inner edge surface of the push button shell 53 facing the capsule compartment plate 3, four needles 52 are fixed in a two-row, two-column arrangement, with the needle tips pointing towards the capsule compartment plate 3. The outer contour lines of the push button housing 53 are smooth and flowing with the outer contour lines of the top cover housing 1 and the base housing 4, so as to prevent the push button assembly 5 from protruding from the overall shape of the device and reduce the risk of patients accidentally touching the push button assembly 5 due to collisions or shaking during carrying.

[0031] like Figure 3 As shown, the capsule compartment plate 3 has two capsule compartments 31 arranged side by side, each capable of holding two powder capsules simultaneously. These two capsules can contain the same drug or two different drugs, thus achieving the purpose of administering two doses of medication or compound medication in a single dose. This reduces the repetitive actions required by patients when taking two powder capsules at the same time, increasing medication efficiency and ensuring patient compliance. Four needle holes 32 are located on the end face of the capsule compartment plate 33 near the push button assembly 5, corresponding to the needles 52. The needles 52 can enter the capsule compartment 31 through the needle holes 32 to puncture the powder capsules. Two needles 52 enter the same capsule compartment 31. The push button assembly 5, located on one side, provides the patient with a fixed end to leverage when pressing the device, ensuring even and easy application of force and guaranteeing that the powder capsules in each capsule compartment 31 can be easily and completely punctured. Two viewing windows 33 are respectively provided on the side of the two capsule chambers 31. The viewing windows 33 are designed with a convex structure, which plays a certain role in magnification. Since the capsule chamber plate 3 is made of transparent material, the patient can easily observe the state of the powder capsules inside the two capsule chambers 31 through the convex structure viewing windows 33, so as to know whether the powder in the capsule has been completely released in this use. It can also remind the patient to empty the empty capsules inside the device in time for the next use of the device.

[0032] like Figures 4-6As shown, the mouthpiece assembly 2 includes a mouthpiece shell 21, a variable diameter interface 22, and a filter 23. The variable diameter interface 22 is fixed to the lower end of the mouthpiece shell 21, and the filter 23 is snap-fitted to the lower end of the variable diameter interface 22. Two circular grids are arranged side-by-side on the filter 23, and the grid area corresponds to the opening area of ​​the capsule chamber 31. By replacing the variable diameter interface 22 and the filter 23, the mouthpiece assembly 2 can be used in single-capsule powder inhalation devices, saving on the production cost of a series of products.
