Abstract

A massage device having a low-frequency voltage pulse generator (IG), which supplies an electromagnetic field coil (MZ), inside of which a human or animal body is placed, on the surface of which a magnet cover or magnet apron (MS) is located inside the field coil (MZ) and which is comprised of small permanent magnet magnetic plates (PM) which are flexibly connected with each other, so that these small magnetic plates (PM) exert a massaging effect on the surface of the body, because they are excited by means of the low-frequency electromagnetic field into pivoting oscillations. The massage effect stimulates the flow of blood and draining of lymphatic fluid and increases the effect of the electromagnetic low-frequency treatment.

Claims
