(b)(4).Two used space pump iv tubing sets, without packaging, were received for evaluation.The sets were received spiked into fenwal 1000ml bags of anti-coagulate citrate dextrose solution.In an attempt to replicate the reported event, the returned sets were primed with the returned solution bags, and loaded into an infusomat space pump as per the instructions for use.The pump rate was set at 325 ml/hr and the sets ran for approximately 30 minutes.During this time, there were no air bubbles observed in any location of the tubing sets and the pump did not alarm any errors.Furthermore, both sets were subjected to occlusion and air pressure (leakage) tests according to specification with acceptable results.Review of the discrepancy management system database performed for the reported lot number did not reveal any abnormalities or nonconformances of this nature.No adverse quality trends of this nature were identified during the complaint review process for the reported catalog number or lot number.Based on the results of this investigation, no specific conclusions can be made regarding the cause of the reported event.The returned sets met requirements according to specification, and the reported failure could not be reproduced.If additional pertinent information becomes available, a follow-up report will be filed.
