Description

Arm massager

Technical Field

The invention relates to the field of medical appliances, in particular to an arm massager.

Background

The theory of meridians of traditional Chinese medicine tells us that the finger tips of the five fingers of a person have meridian points, and each point corresponds to different internal organs in the body. People can check the health condition of the internal organs by kneading the acupoints on the fingers. The massage method comprises the following steps: the finger tips of one hand are pinched with the thumb and index finger of the other hand, and then repeatedly pressed. Can be used for relieving fatigue by massaging body frequently. The acupoints of the human body are massaged by fingers, and the fingers of the massagers are fatigued due to longer massage time; in addition, because the nails of the fingers directly press the skin, the nails are easy to hurt the skin, and deep nail scars are often left on the skin after massage, which is not beneficial to the health of the skin, especially the skin of children. Massage by using a massager has become a requirement for people to massage acupoints to treat diseases and eliminate fatigue.

The massager is a new generation of health care equipment developed according to physics, bionics, bioelectricity, traditional Chinese medicine and years of clinical practice. The multifunctional acupuncture and moxibustion instrument not only has a plurality of simulation functions, so that people can actually feel the wonderful feeling of acupuncture, massage, immunoregulation and other functions, but also has the unique effect of treating hypertension. Can relax muscles, relax nerves, promote blood circulation, strengthen cellular metabolism, strengthen skin elasticity, relieve fatigue, obviously relieve various chronic pains, acute pains and muscular soreness, relax body, relieve pressure, reduce skin wrinkles and the like. Modern social life rhythm causes that most people can only work with both hands in front of an office desk, and the most damaged nature is arms of people, so that people need to massage and keep healthy on the arms frequently.
