The present invention relates to an asthma detection device and a stand-alone asthma detection device. Both of these two asthma detection devices comprise at least one housing having a through hole a rotatable component connected to the housing and a gas detection module comprising a fan and a mini airflow sensor. Wherein, the detection device can be designed as a battery-free asthma detection device by connecting with a processor through a signal delivery unit. In addition, the detection device also can be designed as a stand-alone asthma detection device by further comprising a processor and a power supply module.本發明係有關於一種氣喘檢測裝置及獨立型氣喘檢測裝置,包含:至少一殼體,該殼體係具有一通口;一可旋轉元件,該可旋轉元件係與該殼體相接;及一包含風扇與微氣流感測元件之氣體感測模組。其中,該氣喘檢測裝置可藉由信號傳導單元連接一處理器,設計成免電池的氣喘檢測裝置。而獨立型氣喘檢測裝置可更包含一處理器及一電力供應模組設計成獨立運作之氣喘檢測裝置。1...氣喘檢測裝置13...信號傳導單元21...智慧型手機211...傳導連接單元212...顯示單元
