Two devices without their original packaging were returned for evaluation in used condition.Visual inspection found that the smiths medical devices contained adaptors and an extra stopcock not manufactured by smiths medical.Functional testing involved an occlusion test and found all fluid paths to be free and flowed normally.Verification of the adaptors was performed and found that water was not allowed to flow unless connected to another component, as expected.A review of the investigation documents was performed and deemed adequate and correct.Based on the evidence, the root cause was unable to be determined.It was determined that the root cause was not attributable to a smiths medical manufacturing process.
