A STIMULATION COIL USING MAGNETIC MIRROR AND USE THEREOF

摘要

The magnetic stimulation coil utilizes the magnetic mirror effect to stimulate nerves or muscles in the human body for diagnosis and therapy. The magnetic stimulation coil consists of a coil which generates a magnetic field using an electric current supplied from a power supply and a magnetic mirror which generates a magnetic field similar to the one generated by the coil. In this case, the magnetic mirror is made of ferromagnetic material which has high magnetic permeability. The magnetic stimulation coil with the magnetic mirror effect has advantages over a conventional techniques that it has better power efficiency and less heat generation. These advantages are very important in magnetic stimulators which are used for diagnosis and therapy in the hospital or for improvements and rehabilitations of impaired functions of a human being. Accordingly, the magnetic stimulation coil can be applied to various treatment devices such as urinary incontinence treatment, physical therapy, obesity treatment, arthritis treatment, and various kinds of health promoting devices.
