The major factor influencing drip rate during intravenous infusion using a standard administration set is the variation in the venous pressure of the patient. Creep in the plastic material, though present, is shown to be unimportant. For steady and accurate infusion it is necessary to provide the ordinary gravity-fed administration set with some form of servo-control mechanism.
使用标准输液器进行静脉输液时，影响滴注速度的主要因素是患者静脉压的变化。塑料材料的蠕变现象虽然存在，但已证明并不重要。为实现稳定而精确的输液，有必要为普通重力输液器配备某种形式的伺服控制机制。
