PURPOSE:To take surely a sharp cardiogram by planting a plurality of highly conductive metal needle on one surface of a metal disc like a frog so that the tips of the frog-like metal needles can reach the surface of any animal's body having long fur. CONSTITUTION:Metal needles 2 are planed on a metal disc 1 like a frog. The metal disc 1 and metal needles 2 may be molded integrally with a high conductive same metal material. The metal needles 2 are arranged in the concentric or any other form, and the number of the planted needles, interval between the needles, thickness and length of the needle are not particularly limited. However, while the tips of the metal needles 2 are preferably sharpened so long as these do not dangerously stick in the skin to provide a sharp cardiograph with reduced electric resistance, all tips of the metal needles 2 need to be arranged at a same level. A cable 3 connected to the metal needle 2 is mounted on the edge or rear surface of metal disc 1. Hands and legs are bound with a band made of an insulating material and applied to the rear surface of the metal disk 1 and a surface fastener or the like as a means for pressing the tips of the metal needles 2 to the skin. |
