Event or Problem Description
As per reported by the user facility: while compounding orders it was observed that no solution was being drawn/pumped from tralement (in a syringe on station 13) into the final containers.Station 13 dispensed a total of 17 times prior to the user noticing that solution was not flowing.There was no patient involvement.
Additional Manufacturer Narrative
This report has been identified as b.Braun medical inc.Internal report number (b)(4).B.Braun engineering reviewed the logs provided.The log files show occlusion readings that are consistent with the behavior exhibited by a clogged source line on station 13 near the spike.Priming shows that there is a severe occlusion response, but apex does not check for occlusions during priming.Because there is suction pressure built up in source line 13, there is a decreased sensitivity to occlusions because the baseline readings are compromised once the valve is opened.Due to the very small volume dispenses from line 13, coupled with the compromised baseline occlusion readings, apex does not alarm for occlusions, bubbles, or out-of-weight-tolerance issues, and station 13 is able to dispense in what appears to be a clogged state without alerting the user to any issue.One (1) used transfer set was returned for evaluation.Visual examination of the set noted no defects.The returned sample was occlusion tested per specification with passing results.A retained transfer set was also visually examined and no defects were noted.The retained set was occlusion tested per specification with passing results.A review of our discrepancy management system database found no related or similar discrepancies during the production of the batch.Based on the results of the sample evaluation, no specific conclusions can be made regarding the cause of the reported event.The ifu specifies that the user should watch the source line during priming to ensure that fluid is moving through it during the priming.If additional pertinent information becomes available a follow-up report will be filed.
