Additional Manufacturer Narrative
Qn# (b)(4).The sample was returned for evaluation.A visual exam was performed and no defects were observed.Oxygen entrainment testing was performed and during the setup it was observed that the assembly of the nut adaptor and the upper body was unstable.Even with that condition, the sample was able to be tested on oxygen entrainment testing with no functional issues.After the testing finished, the adaptor was carefully disassembled from the upper body and it was visually inspected.During the visual inspection wear was found on the internal tabs.Based on the investigation performed, the complaint is confirmed.Although the complaint is confirmed, there is not sufficient evidence to assure that this issue was originated during the manufacturing assembly or molding process.The wear on the internal tabs of the adaptor was most likely caused by the end user during the connection of the adaptor into the flowmeter that causes an unstable connection issue.
Event or Problem Description
It was reported that "the user found the connection part between the nut adaptor and the flowmeter was unstable before use.Therefore, a new unit was used instead".No patient involvement reported.
