Embodiment 1

[0027] The propellant is dimethyl ether and carbon dioxide, and the proportion is 27kg of dimethyl ether and 1.5kg of carbon dioxide. When filling, the applicant's product musk pain relief liquid is used as the dosage material, and the weight is 80kg. The dosage is poured into the tank body , then seal it, and fill the tank with dimethyl ether and carbon dioxide in the steel cylinder respectively, thereby making the musk pain-relieving aerosol. Compared with the original musk pain-relieving aerosol, the prepared aerosol is more economical and environmentally friendly, and has no difference in drug efficacy.

Embodiment 2

[0029] Propellant is the same as embodiment 1, proportioning is dimethyl ether 4kg, carbon dioxide 16kg, during filling, is dosage material with the applicant's product ambroxol hydrochloride liquid, and weight is 10kg, and all the other processes are basically the same as embodiment 1. Thereby make ambroxol hydrochloride aerosol.

Embodiment 3

[0031] The rest are basically the same as in Example 1, except that the selected propellant is dinitrogen oxide, the proportion is 8 kg of dimethyl ether, 0.5 kg of dinitrogen oxide, and 5 kg of dosage.

Abstract

The invention relates to an environment protective type casting system of aerosol, which comprises one or several propellants, by employing the environment-friendly type propellant separately, or using the environment-friendly type propellant system consisting of several propellants, the compatibility of the feed liquid can be improved substantially.

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...
