Objectives：The warm needle acupuncture techniques (WNAT) combines the acupuncture effects and heat generated by moxibustion. Although stainless steel needles have been used empirically for WNAT, stainless steel needle has extremely low thermal conductivity and may not deliver designable heat to acupuncture points. The present study compared thermal conductivity of several types of needles made from iron, silver or stainless steel and developed a method enhancing thermal conduction in stainless needle.
Methods：We measured temperatures reaching at 1cm or 2.5 cm from moxa using a digital thermometer (DT-3891F, CEM, Shenzhen, China). and the types of iron, silver or stainless steel needles were compared. Effects of insulation paints on thermal conduction of stainless steel needles were also explored.
Results & Conclusions : Silver needle and traditional needle showed high thermal conductivity while marked heat loss was seen in stainless steel needles. Coating of insulation paint in stainless steel needle prevented the heat loss during WNAT,
