The device involved is tego® connector.The reporter stated that an air bubble was detected on a fresenius 6008® device, resulting in an alarm and blood pump stopping.Upon check, a large air bubble is visible in the bloodline, right after the arterial tego connector in close proximity to the patient catheter.The machine was put to circulate until the air disappeared and then the patient was again connected.The alarms reoccurred again after approximately 3 hours of dialyses.There were 2 tegos used, 1 tego used on the arterial line and used on the venous line.The tego connector that will be returned was initially being used on the patient on (b)(6) 2022 and the event occurred on (b)(6) 2022 during normal dialyses treatment.The event occurred approximately after 1.5 dx treatments.The tego connector was removed immediately after the event was detected.There was no blood loss and no additional treatment was required.There was no patient harm reported.
