Abstract: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, ZNBXD
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.
