Description

Technical Field

[0001] The utility model relates to the technical field of pulmonary drug delivery systems, and particularly relates to a capsule-type powder inhaler. Background Technique

[0002] The powder inhaler is an important part of the pulmonary drug delivery system. Due to its large absorption area and no first-pass liver effect, the pulmonary drug delivery route has received extensive attention in the research and development field of drug delivery systems. Its clinical application has also developed from the traditional local treatment of asthma to the treatment of systemic diseases. Different from general drug delivery routes, pulmonary drug delivery requires the use of a specific inhalation device to complete the dispersion, atomization, and pulmonary delivery of the drug. The inhalation device plays a key role in the pulmonary drug delivery system.

[0003] The Chinese patent with the publication number "CN210644771U" discloses a "capsule-type powder inhaler", which includes a mouthpiece and a drug delivery device. The mouthpiece is detachably connected to the drug delivery device, and a piercing assembly is provided on the drug delivery device; the drug delivery device includes a first drug delivery assembly and a second drug delivery assembly. One end of the first drug delivery assembly is rotatably connected to one end of the second drug delivery assembly, and the other end of the first drug delivery assembly is snap-connected to the other end of the second drug delivery assembly; a first capsule groove is provided in the first drug delivery assembly, and a second capsule groove is provided in the second drug delivery assembly. The first capsule groove and the second capsule groove cooperate to form a capsule chamber, which is communicated with the mouthpiece, and the position of the capsule chamber is correspondingly arranged with the piercing assembly; a first air flow chamber communicated with the first capsule groove is provided on the back of the first capsule groove, and a second air flow chamber communicated with the second capsule groove is provided on the back of the second capsule groove. Both the first air flow chamber and the second air flow chamber are communicated with the outside, so that the powder will not stay in the drug delivery device, and it is more convenient to clean the drug delivery device and the mouthpiece. In the process of loading the drug, the first drug delivery assembly and the second drug delivery assembly need to be completely opened to put the capsule in, which is relatively laborious to operate, and will cause pollution to the internal capsule groove. At the same time, the piercing assembly in the second capsule groove will cause harm to the user under misoperation. Therefore, we propose a capsule-type powder inhaler. Content of the Utility Model

[0004] The purpose of the utility model is to provide a capsule-type powder inhaler to solve the problems of relatively laborious operation, pollution to the internal capsule groove, and harm to the user caused by the piercing assembly in the second capsule groove under misoperation proposed in the above background technique.

[0005] To achieve the above object, the present utility model provides the following technical solutions: A capsule-type powder inhaler, comprising a bottle body, a partition is snap-connected to the top of the bottle body, a medicine bin is fixedly connected to the left side of the bottom of the partition, and the top of the medicine bin penetrates through the partition and extends to the top of the partition. The upper and lower sides of the left side wall of the medicine bin are fixedly connected with limiting tubes, and the limiting tubes communicate with the medicine bin. A rotating ball is fixedly connected to the right side of the top of the partition, a nozzle housing is snap-connected to the top of the partition, a rotating groove is opened on the right side of the bottom of the nozzle housing, and the rotating ball is rotatably connected to the inner cavity of the rotating groove. A mounting plate is snap-connected to the lower side of the inner cavity wall of the nozzle housing in a circumferential manner, a filter screen is embedded in the left side of the top of the mounting plate, and a metal nozzle is embedded in the left side of the inner cavity top of the nozzle housing.

[0015] A dust-proof cover is snap-connected to the outer side wall of the nozzle housing.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: For this capsule-type powder inhaler, by opening the dust-proof cover and rotating the nozzle housing, the nozzle housing rotates through the support of the rotating groove and the rotating ball, and at the same time drives the mounting plate and the filter screen to rotate and move, exposing the medicine bin on the partition plate. After the capsule is placed in the medicine bin, the nozzle housing is reset. At the same time, pressing the pressing block drives the puncture needle on the mounting rod to move under the action of the limiting tube. The puncture needle moves into the medicine bin to pierce the capsule shell, and then inhale by putting the nozzle housing in the mouth to inhale the powder inside the capsule. Thus, it can make the medicine loading of the powder inhaler simpler, and will not cause pollution to the inside of the inhaler, and at the same time avoid the situation that the user is injured due to misoperation.
