摘要
目的分析NICU中低出生体重儿使用微量输液泵与配套注射器的情况，对使用过程中存在的问题进行改进。方法通过误差精度的计算，对20ml无菌注射器设定不同的输液速度（1，5，6，10ml／h）、不同的输液时间（5min、30min、1h），进行对比实验，实验发现20ml无菌注射器泵入到最后阶段，总有0．5～1．5ml的残留液体无法泵入，输液泵显示注射完毕，对此将无菌注射器的尾部放在微量输液泵上的卡槽进行了调整，并将改进后20ml无菌注射器不同的输液速度（5、6、10ml／h）、不同的输液时间（5min，30min、1h）进行对比实验。结果根据对比实验发现误差是真实存在的，不同的输液速度误差精度分别为6．00％、3．80％、2．33％、1．30％。改进后的20ml无菌溶药注射器能够完全泵完所有液体，不同的输液速度、不同输液时间的误差精度优于改进前。结论微量输液泵与无菌溶药注射器经过改进后无药液残留，准确性高，误差小。
Objective To make a concrete analysis of miero-perfusion pump and compatible syringes used in neonatal intensive care unit （NICU） for low birth weight infants, and to find solutions to the defects in apphcation. Methods 20 ml sterile syringes were set different infusion rates （lml/h, 5ml/h, 6ml/h, lOml/h）, different infusion time （Smin, 30min, lh）. Then, the card slot on the micro-perfusion pump where the end of 20ml sterile syringe was placed was regulated. The regulated syringes were also set different infusion rates （Sml/ h, 6ml/h, lOml/h） and time as before. The error accuracy was calculated. Results The results showed that at the end stage of 20ml sterile syringes pumping, there was always 0.5~1.5 ml residual liquid which could not be pumped out, but perfusion pump displayed injection was completed. Before regulation, the error accuracy be- tween different infusion rates of 20ml sterile syringes was 6.00%, 3.80%, 2.33%, 1.30% respectively. However, after improvement, the red, dated syringes could completely pump all liquid out, and the error accuracy between different infusion rates and different infusion time was also superior to pre-improvement. Conclusions Im- proved micro-infusion pump and sterile solution prefiUed syringe have no drug residual, and display high accu- racy and small error accuracy.
