温和灸感传体温度和灸距关系的研究

摘要

Objective To explore the relationship between the receptor temperature and moxibustion distance of mild moxibustion,and provide evidence for clinical moxibustion distance.Methods Mild moxibustion was carried out for 15min by adopting moxibustion shelf,and the moxibustion ash was shook off automatically for once every 3 min.The distance between moxa stick and temperature sensor was set as 2 cm,3 cm,4 cm and 5 cm,respectively,by ruler.The temperature was recorded for once every 2 s with photothermal detection system for moxibustion combustion to form a temperature profile.The initial temperature,maximum temperature and average temperature were observed,and the experimental data were analyzed via SPSS18.0 statistical software.Results The initial receptor temperature was (25.33±0.29) ℃when the moxibustion distance was 2 cm,(25.29±0.05) ℃ when the moxibustion distance was 3 cm,(25.43±0.17) ℃ when the moxibustion distance was 4cm,and (25.16±0.22) ℃ when the moxibustion distance was 5 cm,respectively.The maximum temperature was (74.96±1.20) ℃ when the moxibustion distance was 2 cm,(51.70±0.74) ℃ when the moxibustion distance was 3 cm,(49.33±0.40) ℃ when the moxibustion distance was 4 cm,and (42.50±0.26) ℃ when the moxibustion distance was 5 cm,respectively.The average temperature was (62.40±7.84) ℃-(62.68±7.58) ℃ when the moxibustion distance was 2 cm,(44.77±3.31) ℃-(45.11±3.21) ℃ when the moxibustion distance was 3 cm,(42.72±-3.86) ℃-(43.12±3.54) ℃ when the moxibustion distance was 4 cm,and (38.45±1.67) ℃-(38.50±1.63) ℃ when the moxibustion distance was 5 cm,respectively.The temperature curve showed that the fluctuation range was the maximum when the moxibustion distance was 2 cm,larger when the moxibustion distance was 3 cm,smaller when the moxibustion distance was 4 cm,and minimum when the moxibustion distance was 5 cm.There was no significant difference in the initial temperature of mild moxibustion at different distances,however,the maximum temperature,average temperature and the fluctuation range of temperature curve were closely related to the moxibustion distance.Conclusion The nearer the distance is,the higher the maximum temperature and average temperature as well as the larger the fluctuation range will be,and the farther the distance is,the lower the maximum temperature and average temperature as well as the smaller the fluctuation range will be.According to preliminary analysis,the temperature will be the most suitable when the moxibustion distance is 3 cm-4 cm.%目的:探讨温和灸灸温与灸距之间的关系,为临床施灸距离提供参数.方法:运用艾灸架实施温和灸15分钟,每3分钟自动抖灰一次,通过直尺设置艾条与温度传感器之间的施灸距离分别为2 cm、3 cm、4 cm和5 cm,采用艾灸燃烧光热检测系统每2s记录一次温度值,制成温度曲线图,观察其初始温度、最高温度及平均温度,实验数据由SPSS18.0统计分析.结果:初始温度,灸距2 cm时25.33±0.29℃,灸距3 cm时(25.29±0.05)℃,灸距4cm时(25.43±0.17)℃,灸距5 cm时(25.16±0.22)℃;最高温度,灸距2 cm时(74.96±1.20)℃,灸距3 cm时(51.70±0.74)℃,灸距4 cm时(49.33±0.40)℃,灸-5 cm时(42.50±0.26)℃;平均温度,灸距2 cm时(62.40±7.84)℃-(62.68±7.58)℃,灸距3 cm时(44.77±3.31)℃-(45.11±3.21)℃,灸距4 cm时(42.72±3.86)℃-(43.12±3.54)℃,灸距5 cm时(38.45±1.67)℃-(38.50±1.63)℃.温度曲线显示,灸距2 cm时波幅最大,灸距3 cm时波幅较大,灸距4 cm时波幅较小,灸距5 cm时波幅最小.不同距离温和灸初始温度无明显差异,而最高温度、平均温度及温度曲线波幅与距离关系密切.结论:距离越近最高温度及平均温度越高、波幅越大,距离越远最高温度及平均温度越低、波幅越小,初步分析灸距在3 cm-4 cm时温度最为适合.
