For this purpose, the first correspondence between the nebulized gas volume and the corresponding drug dose may be fitted according to the range of the drug dose contained in the nebulizing cup 120 by actually measuring the nebulized gas volume corresponding to the drug dose in the system, for example, how many grams of drug dose are corresponding to the 1L nebulized gas volume, how many grams of drug dose are corresponding to the 2L nebulized gas volume, how many grams of drug dose are corresponding to the 3L nebulized gas volume, and so on.

And it should be noted that, the higher the requirement on calculating the dosage accuracy of the medicine, the higher the accuracy on calculating the volume of the atomized gas, and correspondingly, the higher the sampling frequency of the flow. Therefore, the high flow sampling frequency can be set as much as possible within the allowable range to improve the accuracy.
