Abstract: A nebulization medicament delivery device is provided, which includes a mouthpiece opening; an airway; at least one first vent configured to introduce external air into the airway, wherein the mouthpiece opening is in communication with the at least one first vent through the airway; a nebulization module including a mesh and configured for nebulization; a first pressure sensor disposed inside the nebulization medicament delivery device and to be air-tightly isolated from the airway, and configured to detect external air pressure outside the nebulization medicament delivery device; a second pressure sensor disposed adjacent to the airway or within the airway, and configured to detect air pressure inside the airway; and a controller, which drives the nebulization module to perform nebulization based on air pressure difference between the external air pressure and the air pressure inside the airway.
