Background

Aerosol therapy refers primarily to aerosol inhalation therapy. Aerosol refers to fine solid or liquid particles suspended in air. Thus, aerosol inhalation therapy uses an aerosolizing device to disperse a drug into tiny droplets or particles that are suspended in a gas and into the respiratory tract and lungs. Inhaled drugs can reach the respiratory tract and lungs of the affected area directly, and thus act faster and more effectively than oral drugs. Because the medicine directly enters the respiratory tract, the dosage of the medicine only needs one tenth of other administration modes at most, and the toxic and side effect of the medicine is obviously reduced, which is particularly important for children and old people. Humidify the air passage and dilute the sputum, and can be widely used for various respiratory diseases. For some diseases (such as cold) which mainly cause virus infection and can be self-healed, the aerosol inhalation treatment can obviously relieve symptoms and shorten the course of disease. The medicine has direct action, has obvious and quick effect on relieving the bronchial asthma and is superior to other treatment modes; the patient can be saved even in critical moments.

But current atomizing device can only continuously atomize, can exhale the liquid medicine after the atomizing to the outside air when the patient exhales to cause the waste of liquid medicine, need stir needs atomizing liquid medicine or powder in advance, the phenomenon that the medicine deposits takes place very easily among the atomizing process, thereby mixes the uneven effect that influences the atomization treatment because of the liquid medicine.
