A Unique Electrical Thermal Stimulation System Comparable to Moxibustion of Subcutaneous Tissue

الملخص EN

Moxibustion strengthens immunity and it is an effective treatment modality, but, depending on the material quantity, shape, and composition, the thermal strength and intensity can be difficult to control, which may cause pain or epidermal burns.

To overcome these limitations, a heat stimulating system which is able to control the thermal intensity was developed.

The temperature distributions on epidermis, at 5 mm and 10 mm of depth, in rabbit femoral tissue were compared between moxibustion and the electric thermal stimulation system.

The stimulation system consists of a high radio frequency dielectric heating equipment (2 MHz frequency, maximum power 200 W), isolation probe, isolation plate, negative pressure generator, and a temperature assessment system.

The temperature was modulated by controlling the stimulation pulse duty ratio, repetition number, and output.

There were 95% and 91% temperature distribution correlations between moxibustion and the thermal stimulus at 5 mm and 10 mm of depth in tissue, respectively.

Moreover, the epidermal temperature in thermal stimulation was lower than that in moxibustion.

These results showed that heat loss by the electric thermal stimulation system is less than that by the traditional moxibustion method.

Furthermore, the proposed electric thermal stimulation did not cause adverse effects, such as suppuration or blisters, and also provided subcutaneous stimulation comparable to moxibustion.
