Event Description
|
The customer would like the run data file investigated to determine a possible cause for the overflow into the platelet concentrate when the additive solution was added.There was not a transfusion recipient or patient involved at the time of the residual wbc testing, therefore no patient information is reasonably known at the time of the event.Donor unit #: 62221739831 wbc count is not available at this time.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.

Manufacturer Narrative

Investigation: one used trima set was received for investigation.Initial observations noted the needle, ac bag and product bags were rf sealed and removed prior to return.Blood is noted throughout the set.Visual inspection noted the mini pinch clamps were on the correct lines and in the closed position.The yellow pinch clamp was in the open position.The set was further inspected for any kinks, missing parts or misassembles and none were found.Lot number and expiry information are not available at this time.Investigation is in process.A follow-up report will be provided.
