Description

Electric signal application pad{ELECTRIC SIGNAL APPLYING PAD}

The present invention relates to a pad for applying an electric signal, and more particularly, to a pad for applying an electric signal in which the pad has an asymmetric shape.

Recently, interest in health of the general public is increasing, and accordingly, various devices for health promotion have been developed and distributed in various ways.

Low-frequency stimulators stimulate local areas of the human body with low-frequency currents generated from low-frequency generators, and are widely used in the treatment of obesity or pain and recovery of fatigue after exercise.

In recent years, with the development of medicine, the mortality rate from various infectious diseases has decreased significantly, but the incidence rate of cerebrovascular diseases, nervous breakdowns, and chronic diseases is on the rise, and the main cause is a busy social life and the resulting accumulation of overwork and fatigue. , Mental tension, irregular eating habits, etc. Due to lack of exercise, blood vessels are narrowed or waste products are accumulated, leading to physical disorders.

In particular, blood vessels play an important role in human life activities. When you are young, the elasticity of blood vessels is strong and blood circulation is ideal. Symptoms may include dizziness, numbness in the hands and feet, systemic weakness, and high blood pressure.

On the other hand, low-frequency therapy devices are becoming popular as physical therapy devices for more effective stimulation of the body part through which blood vessels pass, and conventional low-frequency therapy devices include a low-frequency generator and a plurality of attachment pad-type conductive plates. The low-frequency generator can be operated while attached to the area to be treated, and electrical stimulation is applied to the skin and muscles to release the lumped muscles.

In addition to low-frequency stimulators, various devices that apply electrical signals to the skin or body using wearable pads such as ion topolysis and reverse ion topolysis have been developed.

Since most of the current electric signal application pads are manufactured in a uniform shape, there may be cases in which the function cannot be properly performed depending on the part of the body to which it is attached.
