AIM:To construct the automatic control system mainly composed of sliver needle for heat conduction,and to verify its validity and stability so as to study the action mechanism of sliver needle for heat conduction and exploit patrol equipment for the sliver needle. METHODS:The method of testing was selected for the construction of unit for temperature controlling.The changes of temperature shown in the heat conduction system,the real temperature of needles at the corresponding skin spots,in the middle of and on the tip silver needle was measured in 35 patients with soft tissue leisure. RESULTS:The temperature of control unit shown was positively related to the temperature of real testing(r=0.9991,P< 0.05).The temperature controlling unite could effectively control warming up to temperature of the sliver needle,with high stability(F=30.21,P< 0.01). CONCLUSION:The silver needle temperature controlling unit realizes the automatic control of sliver needle temperature.
