"Water needle" is a non-invasive green health care therapy. It is a new physical therapy instrument which integrates acupuncture skills, hot water foot bath, vibration massage, air billow massage, ozone sterilization and other functions under the guidance of the Nobel Prize in biochemistry, the theory of human meridians, the theory of five elements, the theory of blood circulation, foot reflexology and other theories.

By massaging the soles of feet with ultra-high pressure pulse water column generated millions of times per minute, the whole body meridians can be opened, blood circulation can be accelerated, and metabolism can be improved, so as to achieve the purpose of balancing yin and yang, improving the whole body pain and eliminating diseases. Acupuncture and moxibustion health care has been passed down since ancient times, but the traditional acupuncture and moxibustion health care requires high requirements, requiring experienced doctors to operate it personally, knowing acupuncture points all over the human body like the back of their hands, and requiring patients not to be afraid of acupuncture, which is a bit out of reach for modern people. In order to make the traditional acupuncture health care spread forever in the world, under the guidance of the Nobel Prize in biochemistry, the theory of membrane water channel, the theory of acupuncture and moxibustion in traditional Chinese medicine, the theory of human meridians, the theory of five elements, holographic biology, the theory of foot reflex and the theory of blood circulation, according to the principle of bionics, the "water needle" has set up fifteen models to simulate the feeling of artificial acupuncture or mechanical physiotherapy. For example, the second mode of acupuncture function is a continuous and dense acupuncture-like waveform, which is symmetrical, stable and regular, and its working frequency is 200Hz. It adapts to the law of human life, and the rhythmic rhythm can make people feel relaxed and comfortable. By gradually adjusting the intensity, the acupuncture stimulation gradually deepens, reaching the calf, knee and even the middle thigh. The higher the part that stimulates the sensation, the better the use effect. Another example is the acupuncture and massage function of the third mode: it is a waveform that imitates manual hammering from left to right alternately, which is still symmetrical and regular, and the working frequency is about once per second. It also gives people a relaxed feeling according to the law of human life. Intermittent stimulation can activate the nerves of the foot more effectively, penetrate into the human body strongly, and further enhance the vitality of the meridians. No matter which mode, it can play a very good health care effect.
