The customer reported that during setup for a collection procedure, they received a 'pressure test error' alarm and noted air in the sample bag.The operator stopped the procedure and unloaded the set prior to connecting a donor.No donor was connected at the time of the event, therefore, no patient (donor) information is reasonably known.This product is not available within the us, but this report is being filed due to an alleged failure that could occur on a similarly marketed device platform cleared for use by the fda.

A review of the device history record (dhr) for this unit showed no irregularities during manufacturing that were relevant to this issue.The run data file (rdf) was analyzed for this event.Root cause: review of the rdf confirmed that during the initial loading of the kit, an alarm was generated during the disposables test due to access decay failure.Based on the event description of ¿air observed in the diversion bag line tubing¿, it is likely that the sample bag clamp was not occluding the tubing properly and air entered the sample bag during the disposable test.As the system was unable to maintain the necessary pressure, the alarm was generated.The operator unloaded the cassette and removed the kit to return to terumo bct for evaluation.There were no anomalies found with the returned kit upon inspection of the returned kit.Root cause was determined to be partial occlusion of the sample bag line clamp.Possible causes for this include, but are not limited to, a misassembly of the tubing within the clamp or a clamping advertently being left open.Corrective action: an internal capa has been initiated to evaluate reports of air in samplebag.
