Event Description
|
The customer reported that during a procedure on a rika plasma donation system they received the alarm "return pump track is not in position" 6 times while the donor was connected.Per the customer, the separation set was loaded by a newly trained operator.The procedure was ended and while trying to give rinseback there were "software supervisor error" and "non-recoverable procedure error" received , which resulted in prematurely ending the run with no rinseback.The donor was disconnected and given snacks and oral fluids.No medical intervention or adverse events were reported.Patient id, age and gender are not available at this time.

Manufacturer Narrative

Investigation: upon run data file (rdf) analysis the 234ml of plasma were collected before the run ended with no saline rinsed back to the donor.Donor information from the dlog is as follows: hct=40 weight=216lb.Total blood volume (tbv) calculation was based on assumed height of 4'.Female = 4070 ml tbv.234ml of plasma collected and 200ml of blood left in the channel = 434ml fluid removed from donor.The disposables set was returned to tbct for evaluation.A small dent was found in the return pump line of the separation set.This dent lines up with and is consistent with kinking of the separation set¿s return pump line tubing in the return pump.Through dlog investigation the tbct system engineer found no signs of high pressure or under delivery caused by this kink in the line, in which most likely only plasma passed through at the time of kinking.Photos taken of the pump did not indicate any loading error and the spot where the kink was located is not visible in the photo provided.When watching the same operator load on 31jul2023, it was noticed that she loaded the return pump before loading the collection manifold in a left to right motion, however, tbct is unable to confirm sequence in which the set was loaded on the day of the dd.Operators are taught in class that best practice is to load the collection manifold before loading the return pump and the device operator¿s manual instructs the operator to load the return pump from right to left.Loading in the return pump before the collection manifold is known to cause excess tubing and therefore kinks in the return pump.Therefore, even though it cannot be confirmed a deviation from best practice occurred, for clarification purposes, retraining of set loading is indicated.During investigation, a gap in the software protocol was found where the device can get stuck in a state at the beginning of rinseback if the pump tracks or valves are not working properly.The supervisor alarm stepped in as designed when the protocol did not advance as intended.Before the device was run again, a tbct system engineer went out to the site for a service inspection on 27jul2023.They were able to open and close the pump track without any noticeable interference, hang up, or friction.The device was determined to be working correctly, and paired with the findings on the set; the evidence suggests the issue may have been caused by incorrect operator loading.An email notification was sent by the terumo bct on 28jul2023, to inform the site supervisor and research staff that the device was cleared to use.Investigation is in process, a follow-up report will be provided.
