摘要 本研究旨在观察罐内负压与时间、罐内负压与毫针出针长度的关系。在肾俞穴部位燃拔火罐20 min,通过压力传感器用高速生理记录仪记录罐内负压变化情况。在肾俞穴行毫针刺,以不同负压加拔火罐,测量拔罐前后毫针进针长度变化。观察发现:(1)罐内负压的绝对值与拔罐时间呈逐渐下降趋势,在拔罐20 min后明显变小(P<0.05);(2)罐内负压使毫针向外运动(出针),相同压力下,男性出针长度大于女性(P<0.01)。罐内负压的大小以及性别可影响毫针出针长度。 This study was designed to observe the negative pressure in the cup during cupping, and to investigate the influence of negative pressure on the depth of filiform-needle inserted and retained. In the beginning, the change of pressure after cupping on acupoint BL23 for a span of 20 minutes was recorded. Acupuncture on acupoint BL23 was performed; the filiform-needle was retained and followed by cupping at different levels of negative pressure, and the changes of the depth of needle insertion was measured. The results showed: the absolute value of the negative pressure in the cup goes down with time and is significantly lower after 20 minutes (P〈0.05); the negative pressure in the cup causes the retreat of the inserted needle; and under the same pressure, there is a greater length measurement in needle retreat for male than for female (P〈0. 01 ). The length of needle retreat is related to the pressure in the cupping-cup and to gender.
