A user facility clinical manager reported that a dialyzer blood leak occurred ten seconds after the initiation of the patient¿s hemodialysis (hd) treatment.The blood leak was noted as being an internal blood leak.The leak was visually observed on the upper head of the dialyzer on the arterial side.The machine, a fresenius 4008s machine, alarmed appropriately with a blood leak alarm.Blood leak test strips were not used as the leak was visually observed on the upper head of the dialyzer on the arterial side.There were broken membranes observed near the upper head cap of the dialyzer.The patient¿s estimated blood loss (ebl) was not quantifiable as it was not possible to return the extracorporeal circuit in its entirety.There was no patient injury, adverse events, or medical intervention required as a result of this event.The patient was restarted on a new machine and treatment completed successfully with new supplies.The complaint device was reported to be discarded and not available to be returned to the manufacturer for evaluation.

Plant investigation: the reported complaint was not confirmed as the complaint device was not returned for manufacturer evaluation.A photo and a video clip were provided by the customer.In the photo, the upper header of a dialyzer connected to a machine is shown to be filled with blood.Also, from near the upper dialysate port, blood appears to collect outside of the fibers near the dialysate port area.In the video, a dialyzer is shown to be connected to a running machine.Blood is visible in the upper header near the dialysate port and in the connecting dialysate hose.A production records review was performed on the reported lot.An investigation of the device history records (dhr) was conducted by the manufacturer.There was no indication of product nonacceptance, deviation, non-conformance, rework, labeling or process control failure during the manufacturing process which could be associated with the reported event.The reported lot number passed pyrogen testing, was within sterilization dosage parameters and passed all release criteria.The lot met all release criteria.A definitive conclusion regarding the complaint incident cannot be reached without physical examination of the actual device.Therefore, the complaint is not confirmed.
