AI Technical Summary

Technical Problem

The existing polycystic dry powder inhalation device is dispersed to each capsule compartment when the user inhales drugs, resulting in a reduction in the efficiency of drug inhalation and the need to repeatedly replace the medicine capsule.

Method used

The rotating multi-capsule channel design is adopted. Through the cooperation of the flow guide and the driving part, the suction nozzle is connected to each capsule compartment in sequence, ensuring that it is only one capsule compartment at a time, avoiding suction dispersion, and switching the capsule compartment in sequence through the rotating driving part.

Benefits of technology

It improves the efficiency of drug inhalation, avoids suction dispersion, saves the steps of replacing the medicine capsules, and ensures that each capsule can absorb the medicine with the same efficiency.

Abstract

The present invention belongs to the technical field of medical devices, and particularly relates to a dry powder inhalation device with a rotating multi-capsule channel that is sequentially opened for inhalation, which is mainly used for administering in the form of a dry powder inhalant, and includes: a mouthpiece; a housing, a chamber is formed inside the housing; a plurality of capsule compartments are formed in the chamber and can be communicated with the mouthpiece; a diversion part is movably arranged between the mouthpiece and the plurality of capsule compartments to communicate the mouthpiece with one capsule compartment; a driving part is connected to the housing and the diversion assembly, and the driving part can rotate relative to the housing to drive the diversion assembly to move between the mouthpiece and the plurality of capsule compartments, so that different capsule compartments are communicated with the mouthpiece, solving the problem that: in the existing multi-capsule powder inhaler, when the user inhales the drug through the mouthpiece, the mouthpiece is communicated with each capsule compartment, resulting in the user's suction being dispersed into each capsule compartment, making it difficult for the user to inhale the drug, and thus reducing the inhalation efficiency.
