银质针在温热针法中热传导作用

Heat conduction characteristic of silver needle in heating therapy

目的探讨不同针具在人体组织的热传导性能 ,为进一步研究银质针疗法可能的作用机理提供依据。方法将诊断为腰腿痛病患者 2 3例 ,用不同直径和材料的银质针、不锈钢针刺入腰部的L4、L5横突 ,控制温度分别设定为 60℃、70℃、10 0℃ ,测定皮肤进针点及进针点向针尖 2 5cm处针身的温度变化。结果两种不锈钢针针身温度随着控制温度的增加 ,温度变化不明显(P >0 0 5 ) ;银质针的针身温度升高明显 (P <0 0 1)。结论银质针在人体组织的热传导性能比不锈钢针好 ,温热银质针对慢性软组织损害治疗效果比不锈钢针好 ,可能与银质针良好的导热性能有关。

ObjectiveTo investigates the heat conduction characteristic of three kinds of needle in human soft tissue chronic injury and to research the mechanisms of silver needle therapy.MethodsIron needle and silver needle in different delimiters were used in 23 patients with low back pain and their skin temperature were tested.ResultsThe change of temperature in two kinds of iron needle was not significantly different( P >0.01),but that of the silver needle significantly rised( P > 0.01). ConclusionThe heat conduction characteristic of silver in human soft tissue was better than that of iron needle. The better heat conduction characteristic of silver in human soft tissue maybe related to the better therapy effects.
