Abstract
Abstract Magnetic plasters are prepared from elastic magnetizable plastics sheets, which are either self-adhesive or may be fixed by means of self-adhesive plasters. They may optionally contain substances which stimulate the circulation of the blood in the self-adhesive layer.

Claim 2
Dependent Claim
83 words
A flexible, permanently magnetized plastic sheet compatible with the skin having a flux density of about 50 to 2000 Gauss, a thickness of from 0.2 to 5 mm, and which sheet has alternating positive and negative parallel magnetized strips and the positive and negative poles of the strips are at distances between each other of from about 4 to 10 mm, said sheet being self adhesive to the skin or attachable to the skin by a self adhesive plaster compatible with the skin.
Claim 3
Dependent Claim
26 words
