<p><P>PROBLEM TO BE SOLVED: To provide a magnetic therapeutic device which prevents the drop-out of the magnetic therapeutic device by long-time attaching thereof and perspiration. <P>SOLUTION: The magnetic therapeutic device has a magnetic generator and a polymeric hydrogel for fixing the same to an organism, in which the polymeric hydrogel includes a polymeric matrix formed by copolymerizing and crosslinking a nonionic polymerizable monomer and a corsslinkable monomer, a lubricant and water. The lubricant contains at least≥50 wt.% polymer prepared by polymerizing a polyhydric alcohol monomer and the polymer satisfies the conditions of an average molecular weight 150 to 4,000, water solubility and ä(the number of the ether; groups existing in the polymer + the number of the hydroxyl groups existing in the polymer)/the number of the carbon atoms existing in the polymer}≥1/3 and has at least one unit derived from the polyvalent alcohol monomer having≥3 hydroxyl groups in the repeating unit of the polymer. <P>COPYRIGHT: (C)2003,JPO</p> |
