One (1) confidence kit no needles [product code: 2839-13-000] was returned to the customer quality unit (cqu).For evaluation.Visual examination of the complaint sample revealed that the confidence pump body cracked at the distal tip, where the flex tube exits the part.The crack initiated at the tip and propagated to a length of approximately 2.5 inches.Additionally, it should be noted that the crack formed through the middle of the pump body approximately 70-80 degrees from the parting line.At manufacturing the pump undergoes a 100% high pressure testing in-process where the safety relief valve is actuated ensuring proper functionality and prevention of pump cracking.A definitive root cause cannot be determined at this time.A potential root cause for this failure is that the safety relief valve did not actuate properly to relieve pressure, and that the pump body inner diameter may have been too small.Without the lot number manufacturing record review could not be completed.No systemic trends requiring immediate action have been observed, this complaint file will be closed with no further action required.If information is obtained that was not available for the initial medwatch, a follow-up medwatch will be filed as appropriate.
