(b)(4).One used space pump iv tubing set, without packaging, was received for evaluation.In an attempt to replicate the reported event, the returned set was primed with a normal saline solution 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 20 minutes.During this time, there were no air bubbles observed in any location of the tubing set and the pump did not alarm any errors.Furthermore, the set was subjected to an air pressure (leakage) test according to specification with acceptable results.There were no leakages observed.Based on the results of this investigation, no specific conclusions can be made regarding the cause of the reported event.The returned set met requirements according to specification, and the reported failure could not be reproduced.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.If additional pertinent information becomes available, a follow-up report will be filed.
