The following fields were updated due to additional information: d.10 device available for eval yes.D.10 returned to manufacturer on: 07/08/2020.Investigation conclusion: the customer reported ¿the tubing leaked at the connection of a quad-fuse and the tpn filter at 2:00pm¿.Received from the customer was one used extension set model 10015817 lot unknown.Attached to each of the set¿s four female luers was a male luer with approximately five inches of severed tubing from an unknown set.The set was visually inspected for kinks, incomplete bonding engagements, holes/tears in the tubing or damages to the components.Traces of clear liquid was observed in the set¿s tubing.No other abnormalities were observed on the set during visual inspection.To prepare the set for functional testing a lab microbore filter extension set was attached to the set¿s male luer.An 18 gauge lab cannula was attached to the end of the lab extension set.The received attached partial severed sets were first verified that their male luers were securely attached to the set¿s four female luers connectors, then removed and a lab microbore extension set was attached to each of the female luers.Functional testing was performed by attaching a lab 10ml bd syringe filled with blue-dyed water to each of the lab extension sets and depressing the plunger.No leaking was observed at any of the connection sites, components, or tubing on the set.The set was pressure tested while submerged underwater with the fluid still contained within the set at 30 psi.A lab stopcock was attached to the lab extension set¿s male luer.No fluid or air bubbles were noted to be leaking at any of the connection sites, components, or tubing on the set.The set¿s female and male luer components were inspected under a microscope to determine if any damage was noted.No damage was observed on the components during visual inspection.The received male luers with severed tubing were also inspected under a microscope with no damage observed.Equipment used (visual inspection and testing performed on 14-sep-20).Air pressure regulator with pressure gauge, eq00151, calibration due date: 07-nov-20.Dino lite microscope, eq106199, ncr.Optical ram-cnc, eq08204, calibration due date: 05-feb-21.The device history record for extension set model 10015817 lot unknown could not be conducted because the lot information was not provided.The root cause of the customer¿s report of leaking was not identified as we were unable to replicate the event during functional testing.H3 other text : see h10.
