It was reported that 10 minutes into hemodialysis treatment using a revaclear 400, an "external leakage" as well as "severe blood leak alarm" alarm were generated.Approximately 1/2 ml of blood was observed leaking out of the top of the dialyzer.Treatment was immediately stopped and blood was not returned to the patient.The patient was disconnected from the lines and the machine.Ancef (2g) was given to the patient post dialysis per doctor orders.There was patient involvement however, no patient injury or medical intervention was reported.No additional information is available.

Additional information: d9, h3, h6 and h10.The actual sample and two pictures were received for investigation.An internal blood leak into the dialysate path was observed on the sample, however, no external leak from the dialyzer was observed.The cause of the internal blood leak was found to be from the incorrect placement of a gasket inside of the dialyzer, where the blood was seeping through the support ring of the dialyzer.There were also two photos attached to the record and they were visually inspected.The first photo observed was a dialyzer that was connected to the tubing that was being used during patient therapy.There looked to be blood leaking internally in the dialysate path, with the blood looking to be slipping through the support ring of the dialyzer.The second photo showed the dialyzer from the first photo, just at a different angle.The photos were indicative of an internal blood leak, not an external blood leak.The caused was manufacturing related.A batch review was conducted and there were no deviations found related to this reported condition during the manufacture of this lot.Should additional relevant information become available, a supplemental report will be submitted.
