(b)(4).Complaint verification testing could not be performed as no sample was returned for analysis.A device history record review was performed and no relevant findings were identified.A verification of failure mode reported in the current manufacturing process was conducted as follows: 8 devices were taken from the current production, the samples were functionally inspected, and during the test the issue reported was not observed in the current manufacturing process.Without the device to evaluate, the complaint could not be confirmed and the probable cause could not be determined from the available information.Teleflex will continue to monitor and trend for reports of this nature.If the sample becomes available at a later date a follow up report will be submitted with investigation results.

Qn# (b)(4).The sample was returned for evaluation.A visual exam was performed and there were no defects observed.Functional testing was performed and the unit was connected to 110vac.The unit passed the initial power connect test and navigated through the power-on self-test (p.O.S.T.) with no issues.During the temperature display accuracy test the unit displayed the correct temperatures and properly alarmed in the high temperature scenario.The unit was prepared for the functional bench test where water, an adult breathing circuit (880-36kit), 2-3 lpm of air pressure, and a 382-10 concha smart water column was connected to the unit for a real time operational scenario.In addition to the named test parameters, the neptune operational values were set as follows: temperature was set at 37 c, mode was invasive, full rainout on the moisture scale.The neptune was turned on, values set.The unit successfully negotiated all pre-operational self-tests again and was functioning real time.The unit functioned without any interruption or functional anomalies for approximately 1 hour.Based on the investigation performed, the reported complaint could not be confirmed.Functional testing did not reveal any operational anomalies.
