Abstract

A method and apparatus for electrically heating an acupuncture needle that has been inserted into a subject is disclosed. An applicator unit contains an electrical heating element thermally coupled to an acupuncture needle and directly to the skin adjacent to the acupuncture needle. Regulation and control of the heat supplied by the applicator unit is achieved through the control of electrical power supplied to the heating element. Either temperature or power control can be selected, and temperature indication is provided. In use, after the acupuncture needle has been inserted through the subject'"'"'s skin, the applicator unit is attached to the acupuncture needle and regulated electrical power is applied to produce controlled heat.

Claims

1. The method of heating an inserted acupuncture needle comprising the steps of:

thermally coupling said acupuncture needle to an electrical heating means,

detachably coupling said electrical heating means to said acupuncture needle for support and positioning, of said electrical heating means by said needle,

supplying electrical power to said electrical heating means thereby to generate heat,

controlling said electrical power supplied to said electrical heating means to control the amount of heat generated.

2. The method of claim 1 wherein the step of controlling said electrical power comprises changing said electrical power in response to the temperature of said acupuncture needle.

3. The method of claim 1 including the step of indicating temperature of said acupuncture needle.

4. The method of claim 1 including the step of supplying heat to the skin adjacent to said inserted acupuncture needle.

5. The method of claim 1 including the step of thermally coupling said electrical heating means to the skin adjacent to said inserted acupuncture needle.

6. The method of claim 1 including the step of mechanically clamping said electrical heating means to said acupuncture needle.

7. The method of heating a plurality of inserted acupuncture needles comprising the steps of:

thermally coupling each said acupuncture needle to a separate electrical heating means,

detachably supporting each of said electrical heating means by each of said acupuncture needles,

separately supplying and controlling electrical power to each of said separate electrical heating means.

8. The method of claim 7 including the step of supplying heat to the skin adjacent to each of said inserted acupuncture needles.

9. An instrument for acupuncture therapy of animal tissue comprising:

an acupuncture needle,

electrical heating means for thermally supplying heat to said acupuncture needle,

means mechanically detachably coupling said electrical heating means to said acupuncture needle for supporting and positioning of said electrical heating means by said needle, and

regulating means for regulating the amount of heat supplied by said heating means to said acupuncture needle for supply to said animal tissue.

10. The apparatus of claim 9 including a thermal coupling means for providing a thermal pathway between said acupuncture needle and said electrical heating means.

11. The apparatus of claim 10 wherein said electrical heating means comprises resistance wire wound upon an electrically insulating tube, and said thermal coupling means comprises said electrically insulating tube.

12. The apparatus of claim 10 wherein the combined weight of said electrical heating means and said thermal coupling means is less than 5 grams.

13. The apparatus of claim 10 including a second thermal coupling means providing a thermal pathway between said electrical heating means and the skin adjacent to said acupuncture needle.

14. The apparatus of claim 9 wherein said regulating means controls the electrical power supplied to said electrical heating means.

15. The apparatus of claim 14 wherein said regulating means comprises an electrical power transformer, a potentiometer having two electrical ends and a movable arm, said two ends being coupled to the secondary winding of said transformer, and said movable arm of said potentiometer and one of said ends of said potentiometer being coupled to said electrical heating means.

16. The apparatus of claim 9 including a temperature sensing means thermally coupled to said acupuncture needle, and means coupled to said temperature sensing means for indicating the temperature of said acupuncture needle.

17. The apparatus of claim 9 including a temperature sensing means thermally coupled to said acupuncture needle, said temperature sensor means electrically coupled to said regulating means thereby to maintain said acupuncture needle at a predetermined temperature.

18. The apparatus of claim 9 wherein said electrical heating means comprises an electronic circuit resistor.

19. The apparatus of claim 9 including means for supplying heat to the skin adjacent to said acupuncture needle.

20. The apparatus of claim 9 including clamping means mechanically fixing said electrical heating means to said acupuncture needle.

21. An instrument for acupuncture therapy of animal tissue comprising:

a plurality of acupuncture needles,

a plurality of electrical heating means, each said electrical heating means thermally coupled to one of said acupuncture needles,

supporting means mechanically detachably fixing each said electrical heating means to one of each said acupuncture needles for supporting and positioning each of said electrical heating means by one of each said needles, and

a plurality of regulating means, each said regulating means controlling the electrical power supplied to one of said electrical heating means.
