NMPA in 2004 issued a "notice on the definition of medical nebulizer and other product classification" mentioned medical nebulizer: in the respiratory device system, one end is connected to oxygen, and the pressure of oxygen is used to atomize the agent placed in the nebulizer, and the resulting atomized gas is inhaled into the patient's mouth through the other end of the nebulizer, which is managed as a Class II medical device.
Medical nebulizer is mainly used to treat various upper and lower respiratory system diseases, such as cold, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis and other diseases occurring in the trachea, bronchi, alveoli and chest cavity. Nebulizer inhalation therapy is an important and effective treatment method for respiratory diseases, using a nebulizer inhaler to atomize the medicine into tiny particles, and the drug is deposited into the respiratory tract and lungs by breathing in, thus achieving painless, rapid and effective treatment.
Classification.
There are three main types, the mainstream type of compression nebulizer and ultrasonic nebulizer, and one is a net nebulizer. Nebulized inhalation for the elderly, young children and other special groups of people free of intravenous, intramuscular injection pain, become the tract of choice for respiratory disease therapy. With the popularity of nebulizer inhalation, the choice of medical nebulizer has gradually become the focus. From the technology, in medicine will be ultrasonic nebulizer called the first generation of nebulizer, compression nebulizer called the second generation of nebulizer, net nebulizer for the third generation of nebulizer, these three generations of products present nebulizer three stages of development.

Nebulizer products.
(1) inhaled glucocorticoids: can play a strong local anti-inflammatory effect, commonly used drugs are budesonide
(2) Bronchodilators: bronchodilators are mainly used to relieve bronchospasm, including anticholinergic drugs and β2 agonists
(3) Mucolytics: Ambroxol hydrochloride, acetylcysteine
(4)Antibacterial drugs

In terms of demand, China's medical nebulizer market demand is rising. 2019 China's medical nebulizer market demand reached 6.2 million units, an increase of 34.20% year on year, with a compound growth rate of 38.81%. Among them, the demand for compressed nebulizer reached 4.8 million units in 2019, accounting for 78%, which is the dominant product in the current market; followed by net nebulizer, the market demand reached 1.2 million units, accounting for 19%; the demand for ultrasonic nebulizer was 200,000 units, accounting for 3%. With the improvement of residents' health awareness, the expansion of per capita medical expenditure and national policy support, patients' demand for intelligent micro-net nebulizer products with therapeutic effects continues to expand. The demand for net nebulizer in China in 2020 is about 1.86 million units, up 55% year-on-year. 2022 China's medical nebulizer market demand will exceed 9 million units.

From the General Administration of Customs query data can be seen: since 2017 to 2021 years, medical nebulizer (90192000) exports jumped from 450 million units to 790 million units, total exports increased by about 75% year-on-year; export sales amount jumped from 3.99 billion yuan to 10.28 billion yuan, the total export amount increased by 157% year-on-year.
