Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a comprehensive air flow nebulizer. Background Art

[0002] A nebulizer is a commonly used medical device, mainly used for treating respiratory diseases; its main function is to atomize liquid medicine into water mist, so that patients can directly inhale the medicine into the respiratory tract, thus directly acting on the surface of the respiratory tract. Therefore, atomization medication treatment usually has a good therapeutic effect. Currently, there are mainly two types of nebulizers, one is a compressed air nebulizer, and the other is an ultrasonic nebulizer. Due to limitations in structure and output power, the fineness of the atomized particles is relatively limited; if the two are combined, and ultrasonic atomization is superimposed on the basis of sputtering atomization, the atomization effect will be significantly enhanced; however, if the above two types of nebulizers are directly integrated, not only will the volume be large, but the cost will also be high. The technical solution disclosed in the patent with the patent publication number CN103405835B and the patent name "Comprehensive Medical Nebulizer" solves the above technical problems. When in use, a face mask for buckling on the patient's face is installed at the mist outlet on the side of the nebulizer, and the air inlet at the bottom of the nebulizer is communicated with the air source through a trachea. An air inlet column is fixed at the bottom of the nebulizer, and an air inlet communicating with the inner cavity of the nebulizer is provided in the middle of the air inlet column. The trachea is inserted at the air inlet column. However, the air inlet column is cylindrical, and the trachea is directly inserted on the air inlet column, which is easy to fall off and affects the atomization treatment. Summary of the Utility Model
