- Abstract: The medical ultrasonic nebulizer was introduced in terms of composition,working principle and testing principle and method of the maximum nebulization rate.The testing characteristics of the volumetric and gravimetric methods were compared.A series of experiments were conducted using the whole-unit gravimetric approach.The initial liquid charge was indicated to be the primary factor affecting the maximum nebulization rate,and the influence increased significantly when the nebulizer's nominal volume got expanded.References were provided for medical testing staffs in selecting testing methods.
