Problems solved by technology

[0002] At present, the existing dry powder inhalers have various structural forms, but there are three main problems: one is that the dry powder inhalation rate is low, and research shows that only 8-16% of the drug particles can enter the airway and lungs; Dry powder is easy to be blown out of the device. Some dry powder inhalers have powder to be inhaled in bulk near the nozzle mouth. Once exhaled into the nozzle mouth, especially the elderly and children often exhale involuntarily when using it, the dry powder is easy to be blown off; Third, some nozzles are difficult to clean, and the pollutants on the nozzles will cause cross-infection

Abstract

Disclosed a dry powder gas dispersoid gelatinizing inhaler which inhaling the air current to make drug powder gas dispersoid and gelatinizied in the inhaler, comprising main body (11) and a sucker connector (12) connecting the main body. It is characterized in that a funnel-type charged hole (1) is mounted in the main body (11) through the tube of vortex cavity which also is through the sucker (9) of the sucker connector (12). The invention can significantly increase drug inhalation to get more drug particles reach lower respiratory and alveolar, while avoiding the drugs exhaled from device by the user, preventing cross-infection, reducing general side effect, and remarkable lightening economical pressure.

Description

technical field [0001] The invention relates to a medical device, in particular to a dry powder inhalation device, in particular to a dry powder aerosolization inhaler capable of aerosolizing medicinal powder. Background technique [0002] At present, the existing dry powder inhalers have various structural forms, but there are three main problems: one is that the dry powder inhalation rate is low, and research shows that only 8-16% of the drug particles can enter the airway and lungs; Dry powder is easy to be blown out of the device. Some dry powder inhalers have powder to be inhaled in bulk near the nozzle mouth. Once exhaled into the nozzle mouth, especially the elderly and children often exhale involuntarily when using it, the dry powder is easy to be blown off; The third is that some suction nozzles are difficult to clean, and the pollutants on the suction nozzles will cause cross-infection. Contents of the invention [0003] The purpose of the present invention is t...
