Description

Technical Field

[0001] The utility model relates to the technical field of respiratory products, in particular to a DPI inhaler trainer. Background Technique

[0002] In the treatment of respiratory diseases, inhalation therapy has been widely recognized and clinically applied. These devices have relatively high requirements for inspiratory flow rate. Peak inspiratory flow has an important impact on the ejection dose of drugs and the pulmonary deposition rate of drugs. Different types of dry powder inhalers (DPI) have different requirements for inspiratory flow rate. Therefore, due to their different internal resistances, to varying degrees, they also affect the magnitude of the inspiratory flow rate.

[0003] The Chinese patent with the publication number CN211798625U discloses a DPI inhaler trainer. By opening a ventilation port at the bottom of the breathing bottle and arranging a rotatable rotary turntable at its bottom, the top surface of the rotary turntable is divided into three exhalation areas. Rotating each exhalation area to directly below the ventilation port can realize the separate inspiratory flow rate training of three inhalants, namely tiotropium bromide, turbuhaler, and accuhaler. That is, the resistance conversion is realized by the number and diameter of the intake holes in each exhalation area. Then, by observing that the buoy is carried above the marking line by the airflow, it indicates that the inspiratory volume meets the standard, thereby indicating that the inhaled drug dose meets the standard.

[0004] Although the above DPI inhaler trainer can solve the corresponding technical problems, its mouthpiece is exposed to the air when not in use, resulting in the surface of the mouthpiece being prone to bacterial growth and dust attachment. As a result, subsequent users will unconsciously inhale bacteria and dust into their mouths during use, affecting health. Therefore, a DPI inhaler trainer is proposed. Summary of the Utility Model
