  • Patent number: 7537605
    Abstract: An apparatus and method that is effective for the treatment of skin itch and skin rash is disclosed. The apparatus is contained within a body which can be easily manipulated with one hand, and which is powered by a self-contained battery. Also contained within the body is a heating means, controlled by a thermostat, a temperature selector if the heating means if intended to provide multiple temperatures, and means to warn the user when the desired temperature is reached. In addition the apparatus includes means to apply the heat in a cyclical manner, in which the heat is repeatedly applied and removed, with a cycle time and pulse width in which is controlled by user by means of a control located on the body heater and some other elements that can ensure only one substantially unique temperature is used.

  • Publication number: 20080053912
    Abstract: We propose unipolar magnetic particles as medicine carriers. The whole surface of each particle is monopolar, being either north or south. The particles repel each other and are repelled by same polar external magnet. Four or more magnets that are stereo located to apply the forces to a swamp of particles from all directions may, therefore, relocate the swamp, squeeze it, reshape it, and allow it to expand.
