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. 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.

Claims

1. An electrical apparatus for treating an skin problem like skin lesion, condition and disease, through the controlled application of heat, comprising:

an heating means with an interface for contacting the skin and for providing one or more specific temperature(s) inside the range of about 46-62degree C. for a desired time and the interface being big enough to heat a diseased skin area for treating a skin problem;

an power source supplying power for the heating means;

a controlling means for maintaining the interface within ±

about 1 degree C. around the specific temperature during the desired time;

a housing having a contact end, the heating means positioned at or within the contact end, the controlling means located within the housing, and the power source means connected to or in the housing.

2. The apparatus according to claim 1 wherein the controlling means controls the interface within the best effective temperature range for a specific treatment in the desired time;

the best effective temperature range being a range within the working temperature range for that specific treatment, being not so high as to cause burning or significant discomforts, being high enough to minimizing the side effects such as edema.

3. The apparatus according to claim 1 wherein the controlling means controls the interface within the working temperature for a specific treatment in the desired time.

4. The apparatus in accordance with claim 1, further comprising signaling means to indicate that the heating means has reached the specific temperature.

5. The apparatus in accordance with claim 1, further comprising a selecting means allowing for selecting one of a multiplicity of temperatures, each good for a specific treatment, inside the range of 46-62 degree C., the interface providing the selected temperature without limitation in range.

6. The apparatus in accordance with claim 5 wherein each selected temperature supposing to be a best effective temperature for a particular treatment and, so, being inside 46-62 degree C.

7. The apparatus in accordance with claim 6 wherein the controlling means controls the interface within the working temperature for a specific treatment in the desired time.

8. The apparatus in accordance with claim 1, further comprising means to change the interface temperature for periodic heating of the skin, and wherein this means may provide control of frequency and/or duty cycle of said heating.

9. The apparatus according to claim 1 wherein the interface being a separate part of the heating means and being heated by the heating means.

10. The apparatus according to claim 9 wherein the controlling means controls the interface within the best effective temperature range for a specific treatment in the desired time;

the best effective temperature range being a range within the working temperature range for that specific treatment, being not so high as to cause burning or significant discomforts, being high enough to minimizing the side effects such as edema.

11. The apparatus according to claim 1 wherein the interface temperature is a specific temperature inside the range of about 49-53 degree C. during the desired time.

12. The apparatus according to claim 11 wherein the controlling means controls the interface within the best effective temperature for a specific treatment in the desired time.

13. A method for treating an skin problem like skin lesion, condition and disease, comprising the following steps:

selecting a heater with an interface for contacting and heating the skin;

raising temperature of the contact skin area to a predetermined working temperature for a specific treatment and within about 46-62 C to a desired precision;

and maintaining the temperature of the skin area within a certain range for a desired time.

14. A method in accordance with claim 13 wherein the certain range means within about ±

1 degree C.

15. A method in accordance with claim 13 wherein the certain range means within the working temperature for the specific treatment.

16. A method in accordance with claim 13, further comprising a step to change the skin temperature for periodic heating of the skin, and wherein this step may provide control of frequency and/or cycle of said heating.

17. A method in accordance with claim 13, further comprising a temperature selecting step for allowing selecting one of a multiplicity of temperatures, each good for a specific treatment, inside the range of 46-62 degree C., the skin being heated to the selected temperature without limitation in range.

18. A method in accordance with claim 17 wherein the certain range means within about ±

1 degree C.

19. A Apparatus for treating an skin problem like skin lesion, condition and disease, comprising the following steps:

a heater for providing laser, microwave, infrared light, ultrasound or any other energies capably of heating the skin to a specific temperature based on the type of a treatment inside the range of about 46-62 degree Celsius;

a detecting means for directly detect the temperature of the skin and/or the temperature of the very top of the material such as a grid for separating the skin from the heater, if any, that contact the skin;

a controlling means for controlling the heating energy so to control the skin temperature within the best effective temperature range for that specific treatment for a desired time.

20. A apparatus in accordance with claim 19, further comprising a selecting means allowing for selecting one of a multiplicity of temperatures for specific treatments.
