The reasons for the lack of suction of the fire pot may include the lack of airtightness of the fire pot itself, insufficient combustion of the fire source and inappropriate adsorption parts, etc., which should be targeted for checking and timely replacement or selection of suitable parts.
1. Before the operation of fire cupping, the integrity of the fire can should be carefully checked and whether there are cracks or fissures, etc. Since the operation of fire can is mainly based on the principle of negative pressure, if the fire can itself is not sufficiently airtight to lead to gas leakage, the problematic fire cans should be replaced in time for the operation.
2. When performing fire cupping operation, usually choose the concentration of 95% alcohol as the fire source to burn the air inside the tank to form negative pressure, if the degree of alcohol is too low for the fire source, or burning is not sufficient, it will lead to suction reduction, so the operation should be used to burn the air with a suitable fire source.
3. The choice of cupping site should be muscle rich, if you choose to cupping for the joints of the limbs of the slender place easy to lead to leakage, or part of the selection of large caliber cupping to the bones of the prominent and muscle thinning will leak, so you need to choose the appropriate parts and suitable cupping operation to avoid air leakage.
If cupping treatment is needed, it should be completed under the operation of a professional physician or physiotherapist, and should not be operated by oneself to avoid adverse effects such as burns.
