An external air source driven atomization device

Abstract

The invention discloses an atomization device driven by an external gas source, comprising: an external gas source, a gas drive control module, an atomization generator, an online particle size detection mechanism, and a particle size control feedback module. The external gas source is used for atomization The generator transports gas, and the particle size online detection mechanism is used to detect the particle size of the atomized aerosol generated in the atomization generator in real time, and feed back to the particle size control feedback module in real time. The particle size of the aerosol is controlled by the gas drive control module to adjust the gas delivery pressure and flow rate of the external gas source so that the particle size of the atomized aerosol meets the preset particle size threshold. The particle size of the atomized aerosol in the atomizer can be controlled in real time through the gas drive control module, particle size on-line detection mechanism and particle size feedback module, so the content of the atomized aerosol with the required particle size can be increased, and the atomization rate can be improved. The deposition rate of drugs in the lesions of the respiratory tract improves the efficiency of drug use and reduces the waste of medical resources.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an atomization device driven by an external air source. Background technique [0002] Nebulization device is a commonly used medical device for the treatment of respiratory diseases. The atomization device can deliver the atomized drug to the diseased part of the respiratory tract in the form of aerosol, so as to achieve the purpose of humidifying, relieving bronchospasm, eliminating airway edema, and promoting the discharge of airway secretions. Among them, different aerosol diameters can be deposited on different parts. Studies have shown that aerosol diameters of 5-20 μm are mainly deposited in the mouth, nose and upper respiratory tract; aerosols of 2-5 μm are mainly deposited in small bronchi and bronchioles; aerosols of less than 2 μm are mainly deposited in alveoli. Therefore, ideally for different respiratory diseases, it is necessary to choose atomized drugs with diffe...
