2.4 Working principle
Principle of nebulization:
The mesh nebulizer works by electrically activating a piezoelectric
ceramic actuator (PZT), which transmits the generated vibration to the
adjacent carrier plate and the polymer mesh with numerous openings.
The vibration actively forces the liquid medication out by physically
breaking the surface tension of the solution through the mesh
openings, resulting in final nebulization. After the patient has put on
the mask covering the nose and mouth, the nebulized medication is
inhaled into the body through inhalation.
Principle of treatment:
The respiratory system is an open system. After inhalation, the
atomized drug can be absorbed directly through the mucous
membranes in the patient's oral cavity, throat, trachea, bronchi and
alveoli, etc. to achieve the purpose of treatment.
3. Device description
The nebulizer consists of the main unit, the medication cup and the
mask.
