1, suction and extraction time and suction and extraction force The general suction and extraction time is 10 to 15 minutes. Short for 5 minutes, up to 30 minutes. If the patient meets the tight pain is particularly difficult, you can start earlier. If the patient feels comfortable, the suction force of the can is not very large, and the local muscles and more plump, the time can be longer. Physical thinness and weakness, the power to be small, time to be short, the number of cupping to be less; physical fitness and muscle plump, can suction force to be large, the number of cupping to be more, suction time to be long. The patient is more sensitive, less tolerant, the time of cupping should be short; the patient is more tolerant, the time of cupping should be long. New patients receiving cupping therapy (patients receiving cupping therapy for the first time) should have a shorter time. Older patients who often receive cupping therapy, suction and extraction time should be longer. Need to excite, improve the functional state of the body, suction and extraction time should be short, suction and extraction force should be small, the number of cans should be less. For example, flash cupping, generally 5~10 minutes, is used to treat all kinds of paralysis. For all kinds of pain, need to inhibit, suction and extraction time should be long, suction and extraction force should be large. 2, the course of cupping Acute diseases cupping treatment once a day, chronic diseases cupping treatment once every other day, 10-15 consecutive treatments for a course of treatment. 3, cupping marks Cupping marks purple and black and dull, is a sign of blood stasis and cold. If there is a large black and purple mark when walking the can, it suggests that there is wind-cold. If the marks do not recede for several days, it often indicates that the disease has a long history and needs more treatment for a period of time. The marks are scattered purpura, varying in depth, for the signs of qi stagnation and blood stasis. Pale purplish blue with plaques, suggesting deficiency of qi and blood stasis. Bright red can mark, suggesting yin deficiency and fire exuberance. After suction, there is no can mark or although there is, but immediately disappear after starting the can and return to the normal color, suggesting that the disease is still light. However, obese and anemic patients, there is often no suction and extraction marks. Being sucked and plucked parts in 5 minutes, there are obvious signs of sucking and plucking, indicating that the part is a sick part. In the back of a large area after walking cans, such as red dots concentrated in the vicinity of an acupuncture point, suggesting that the acupuncture point where the viscera abnormal. 4, local itching A very small number of patients in the process of cupping or after cupping, the local skin plucked itching and other symptoms. This is because the patient’s local skin is too sensitive to cans, especially the repeated use of bamboo cans. This phenomenon can not make special treatment, generally take the can after the itching symptoms slowly disappear, if necessary, external rub dermatitis ping to stop itching. If necessary, rub dermatitis to stop the itching. For this kind of patients, different kinds of cans can be replaced, alternating between the parts of the cupping treatment. Fainting During cupping, a very small number of patients may suffer from fainting or even shock. This is mainly due to the patient’s excessive tension in the first time cupping, too sensitive to pain, weak or too hungry and fatigue; or too much suction power of the fire can; or cupping time is too long and caused. At this time, the patient feels dizzy, upset and want to vomit, pale, cold limbs, cold sweat, shortness of breath, pulse frequency and small. Treatment should immediately remove the can, make the patient lying on the bed, drink some hot water or sugar water. Slightly heavier patients can be acupressure nasolabial groove on the upper 1/3 of the Renzhong point, or is located on the back of the hand, the thumb and forefinger bifurcation of the Hegu point, you can return to normal. Continue to lie flat on the bed for 15 minutes before leaving the treatment room. 6, the treatment of blisters Local skin delicate or cupping for too long, or suffering from the disease is rheumatism, edema, it is easy to occur cupping local skin blisters, single or multiple, scattered or gathered. There are times when blistering is not a bad thing, and some intentionally use blistering therapy. However, blisters should be prevented as much as possible during cupping so as not to interfere with continuous treatment. As long as careful, sometimes suction and extraction force is too strong, especially in summer, sweating more, cupping time should be appropriately short. If blisters occur, generally small scattered blisters can not be dealt with, the patient is asked not to break, so that it is naturally absorbed; if the blisters are large and hairy, in the routine iodine povidone or alcohol disinfection, with a syringe, in the edge of the blisters stabbed, the water will be drawn out, and then applied to the purple ointment or scalding cream can be. If in order to prevent infection, or if infection occurs, antibacterial drugs can be taken. 7, the treatment of burns in the use of flash fire method of cupping, if dipped in 95% alcohol is too much, burning alcohol can be dripped onto the patient’s skin, or the mouth of the can, the inside wall of the can is dipped in burning alcohol, often resulting in scalding of the skin. Therefore, cupping burning cotton balls to be slightly pinched, dipped in 95% alcohol dosage should be moderate, in order not to drip appropriate. This can avoid the occurrence of burns other than. For mild skin burns without special treatment, there is pain in the patient can be local topical application of green ointment or oil, generally 2 ~ 3 days within the symptoms of natural subsidence; for the emergence of blisters of the skin burns, to be in aseptic operation to suction blisters within the liquid to the exposure treatment, can be externally coated with scalded potion, generally 2 weeks or so the traumatic lesions can be cured.
