Medical device for treating skin itch and rash

摘要

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. The method, which is related to the apparatus as its governing principle, includes the application of heat at a precise, controlled temperature, for a specific period of time, t the skin at the location of the itch or rash. The temperature used depends upon the nature of skin discomfort, but is generally inside the range between 46-62° C. The temperature variation is generally controlled within +/−0.5° C. although it can be wider or narrower depends upon the nature of the itch treatment. In addition, the method includes a pulsating application of heat to the skin area, in which the heat is alternately applied and removed at a rate of approximately 1 second, with a total application time of between 10 and 30 seconds.
