A fresenius field service technician (fst) was called onsite after a usr facility biomedical technician (biomed) reported that the blood pump rotor guide on a 2008t machine came off and cut into bloodline tubing during the patient's hemodialysis (hd) treatment.It was stated upon initial reporting that the patient did not experience a serious injury or require medical intervention as a result of the reported issue.The patient was transferred to another machine where treatment completed successfully with new supplies (brands unknown).The fst replaced the rotor to resolve the reported issue.The machine passed functional testing and was returned to the customer.The sample is available to be returned to the manufacturer for physical evaluation.Additional information was requested however a response was not received.

Manufacturer Narrative
|
Plant investigation: a complaint sample was returned to the manufacturer for physical evaluation.The blood pump rotor was returned with slightly loose guide sheaves (guide sleeves) on both rear tubing guide pins, however the sleeves could not be removed from the pin.There are signs of debris (shavings) on the rear guide pins from the guide sheaves.There is no deformation on the rear guide sheaves.No discrepancies were found on both front guide pins and sheaves.A missing ball bearing was encountered, which caused the locking lever to be loose.The rotor was installed into the blood pump module in as-received condition for testing.The returned rotor did not puncture the bloodline and there were no leaks during testing.The rear guide sheaves remained intact and did not fall off the pins.There was no damaged or deformation on the rear guide sheaves during testing.A records review was performed on the reported serial number.An investigation of the device manufacturing records was conducted by the manufacturer.There were no non-conformances, or any associated rework identified during the manufacturing process which could be related to the reported event.In addition, the device history record (dhr) review confirmed the results of the in-progress and final quality control (qc) testing met all requirements.The investigation into the cause of the reported problem was able to confirm the reported failure mode.
