It seems that once the spinning function is engaged by twisting on the iv tubing, the part of the iv tubing that twists on no longer stays attached to the spiros.This ultimately makes it easy for the iv tubing to detach from the spiros because it then acts more like a slip-tip than a luer lock.And unfortunately, since the tubing detached from the spiros and the spiros was still attached to the microclave closest to the patient, the line remained open, allowing for the backflow of blood out of the patient.Part# ch2000s-c, lot# 13490092.The separation occurred between the primary set line and spiros.Chemo was infusing the day before the incident.After the patient was just infusing continuous fluids.The blood loss was estimated at 30mls.The event resulted in a decrease of hemoglobin level.The set up was a new primary line connected to a single lumen port with ns infusing continuously.We are returning the product to the manufacture.
