Description

Technical Field

[0001] The invention relates to the technical field of atomizers, and in particular to a silent atomizer with a heating function. Background Art

[0002] In recent years, due to environmental pollution, large-scale mutation of bacteria and viruses, the incidence of respiratory infections or non-infectious inflammation in children has continued to rise. The most commonly used treatment method in clinical practice is to use anti-inflammatory drugs, hormones, leukotriene blockers and other drugs for positive pressure ventilation nebulization. Positive pressure ventilation nebulization technology has now become relatively mature and has a good effect on alleviating and treating respiratory diseases. The medical nebulizer atomizes the liquid medicine into tiny particles, and the medicine enters the respiratory tract and lungs through inhalation, thereby achieving painless, rapid and effective treatment. It is a Class II medical device.
