摘　　要：目的实验室制备恒速灌肠器用于测定肛门直肠控制液便的能力,定量评价大便失禁的严重程度。方法运用4个普通灌肠器(各由一个容器和一条与其底部相通连的引出皮管所组成),改变其几何形状和空间结构,重新组合成一个恒速灌肠器。结果实验室制备的恒速灌肠器能够输出足以克服直肠任何阻力的脉冲恒速水流(可以调试为标准速度1ml/s)。失禁组水保持试验测定分值为(228.08±215.11)ml,而对照组则为(1434.17±304.50)ml,二组间比较显示有显著性意义(P<0.01)。结论由恒速灌肠器提供的脉冲恒速高压水流能够用于肛门直肠控便功能的评估,恒速灌肠法具有客观、即时、定量的优点。Objective To design a speed-constant rectal lavage apparatus for assessing the rectal and anal function in liquid stool continence and the degree of fecal incontinence. Method The apparatus was assembled by four common rectal lavage apparatuses, each with a container and a drainage tube. Results The device could output a pulsed and speed-constant water stream with high pressure, capable of overcoming any rectal resistance change. The test for liquid continence in 12 patients with incontinence (n=12) and 12 normal control subjects (n=12) found that the retained liquid volume was significantly lower in the incontinence group than in the control group (P<0.01). Conclusion Fecal incontinence could be evaluated with the speed-constant rectal lavage apparatus, which yields objective and quantitative results.
