Abstract

The invention discloses a pain-alleviating cryospray device provided with a specific aerosol valve and an actuator. A pain-alleviating cryospray is prepared from components in percentage by mass as follows: 80%-95% of a cryogen, 3%-19.5% of a pressor and 0.5%-2% of a wetting agent. 0.5%-2% of the wetting agent is weighed in percentage by mass and poured into an aerosol can through a trace and precision metering device, the specific aerosol valve is mounted, and the aerosol can is sealed; the aerosol can is filled with 80%-95% of the cryogen in percentage by mass and then filled with 3%-19.5% of the pressor, the specific actuator is added, and the pain-alleviating cryospray device is obtained. The cooling holding time of the cryospray is shorter, bad reactions such as cold burn and the like can be avoided, and the instant cooling temperature can be adjusted between subzero 10 DEG C and subzero 30 DEG C. The product can be rapidly atomized when sprayed out, is sprayed in a bunchy fog manner and has certain impact sense to enhance the pain-alleviating effect.

Description

technical field [0001] The invention belongs to the field of aerosol technology, and in particular relates to an analgesic freezing spray with a specific aerosol valve and actuator, and also relates to a preparation method of the aerosol product. Background technique [0002] The aerosol product refers to a product in which the composition is sealed and contained in an aerosol can equipped with an aerosol valve at the injection port, and is sprayed out in a predetermined form under the pressure of the propellant. The main spray forms of aerosol products are mist, foam, powder or micelles, among which mist is the more common spray form. [0003] The liquefied gas in the aerosol can is instantly sprayed out in the form of mist. Due to the heat absorption effect of gasification, it absorbs a large amount of surrounding heat and quickly cools down, so as to achieve the effects of cold therapy such as pain relief, anti-swelling, and reduction of secondary damage.
