Vacuum cupping device absorbs the advantages of traditional cupping device, overcomes the shortcomings of traditional cupping through high-tech means, and rejuvenates the ancient cupping method of traditional Chinese medicine. The main feature is that the tank is transparent, and the negative pressure in the tank can be adjusted at will according to the patient's physical condition and illness, which is convenient for observing the skin changes in the tank and grasping the cupping time. Compared with traditional cupping, it has the same curative effect, but it is safer to use, has no scald, is simple to operate and is not easy to break, and is suitable for hospitals and families. Scholars at home and abroad have found that when the human body is pulled by negative pressure, a large number of bubbles will overflow on the skin surface, thus strengthening the gas exchange in local tissues. Through examination, it was also observed that negative pressure caused local capillary permeability change and capillary rupture, and a small amount of blood entered the gap, resulting in blood stasis, destruction of red blood cells, release of hemoglobin and autohemolysis. In the body's self-regulation, it has the effects of promoting qi and blood circulation, relaxing tendons and activating collaterals, relieving swelling and pain, expelling wind and removing dampness. , and play a positive role in stimulating it, prompting it to return to normal function.

The regulating function of cupping is based on negative pressure. First, it regulates the nervous system. Because of hemolysis, it gives the body a series of benign stimuli, which act on the peripheral receptors of the nervous system and transmit to the heart and reach the cerebral cortex. In addition, the warm stimulation of cupping on the local skin is introduced into the central nervous system through the reflex channels of skin receptors and vascular receptors, which makes it reflexively excited, thus regulating the excitement and inhibition process of the cerebral cortex, making it tend to be balanced, strengthening the regulatory function of the cerebral cortex on various parts of the body, making the corresponding tissues of the affected skin metabolize vigorously, enhancing the phagocytosis, recovering the body, adjusting the imbalance of Yin and Yang, and gradually curing the disease.
