摘要
目的评估不同输液泵组合及夹管时间长短对临床应用输液泵系统静脉给药时流速误差的影响。方法实验测试流速为100 m L/h,溶媒为灭菌注射用水,对两种品牌输液器和两种输液泵的4种不同组合进行24 h无间断的流速检测,每种组合重复5次。结果 4种组合中,除了组合2ZNBXD型输液泵和贝朗输液器以外,其他3组组合的误差都控制在IEC允许的±8%误差范围之内;从夹管时间上分析,可以看出随着时间的延长,流速存在着逐步下降的趋势,尤其是组合4 ZNBXD型输液泵和康德莱输液器最为明显。结论只有严格筛选在误差范围之内的输液器,才能更好地满足输液泵的流速精度要求,提高临床输液安全保障;同时建议临床每隔6~8 h更换一次夹管位置。
Objective To assess the impact of different combinations of infusion pumps and clamping tube time on the flow rate error of the clinical application of intravenous infusion pump system.Methods The experimental test flow rate was 100 mL/h, and the solvent was sterile water for injection.The flow rate of 24 h without interruption was detected for four kinds of different combinations of two kinds of brands infusion sets and two kinds of infusion pumps, five times repeated for each combination.Results In addition to the second combination of ZNB-XD infusion pumps and B. Braun infusion sets,the errors of the other three groups were controlled within IEC allowable error range of ± 8%. There was a flow rate of gradual declining with clamping tube time, especially in the fourth combination, ZNB-XD infusion pumps and Kindly infusion sets. Conclusion The rigorous tests should be carried out for different combination infusion pumps and sets, before the clinical application of intravenous infusion pump system, to meet the system precision and improve the clinical transfusion security. The suggestion for the clinical was recommended that pinch position should be replaced every 6～8 h.
