Abstract
Description
technical field
[0001] The invention relates to an aerosol environment-friendly projectile system for medical treatment. Background technique
[0002] Aerosols are generally composed of doses and propellants. According to the dispersion of the doses in the propellant, aerosols can be divided into three types: solution type, emulsion type and suspension type. When in use, the aerosol is ejected from the nozzle of the aerosol valve. The propellant is the power source of the aerosol and one of the indispensable key parts of the aerosol product. The aerosol product relies on it The stored energy can be ejected and used. And the application effect of the product, in addition to the factors of the formula and preparation process itself, and the combined effect of the valve and the actuator, the performance, proportion and type of the propellant will also have a greater impact on the effect. According to whether the propellant used in the aerosol is Freon or not, the aerosol is d...
