Research on the thermal effect difference between DAJ-4 multi-function moxibustion instrument and traditional moxibustion

Objective To compare the thermodynamic properties of moxibustion and thermal effect after moxibustion between the traditional moxibustion therapy and DAJ-4 multi-function moxibustion instrument.Methods Three healthy volunteers were selected.Separately,the traditional moxibustion and the moxibustion instrument were applied to Neiguan(PC 6) and Zusanli(ST 36),repeatedly for 3 times.The infrared imaging equipment was adopted to film the thermal figures of human body at different time points before and after moxibustion every 5 min.The temperature at the local moxibustion sites and the distal points [Laogong(PC 8),Yinlingquan(SP 9)] on the limbs was measured.Results In 15 min with the traditional moxibustion therapy,there was burning feeling in the moxibustion sites with the highest temperature of(41.43±0.13)℃.In 15 min with the moxibustion instrument,the highest temperature was up to(36.97±0.13)℃.In comparison of the temperature at the distal limbs before and after moxibustion,After 20 min with the traditional moxibustion therapy,the temperature at the distal limbs was reduced by about 0.6 ℃ as compared with that before moxibustion.After 20 min with the multi-function moxibustion instrument,the temperature at the distal limbs was increased by about 1.1 ℃.Conclusion The multi-function moxibustion instrument achieves better effect of increasing temperature at the distal limbs than that of traditional moxibustion.
