The patient completed treatment without further need for intervention.Evaluation: the sample returned, it consists in one unit for the returned sample was received inside of a plastic bag which is not its original packaging.Two photos were attached to the complaint, valve is not attaches to the tube.The product was received with the valve (asv) separated from the tube, it can be observed residuals of solvent around the tube tip, but the unit was already separated.It cannot be performed the pull test to confirm the unit is acceptable.These two mitigations are related to this failure reported to avoid the occurrence: production personnel starts verifying and fill the solvent container to the maximum level at the beginning of shift and the middle of shift.Production personnel joins all components immediately after solvent application., this to avoid any potential weakness in the bonding and both parts being stick together.These two indicators are key to ensure the piece has the right amount of solvent applied to make a correct bonding, any of these it could result in a weak bonding.Production personnel performs a 100% visual inspection to bond between valve to coil assembly (tube) production performs a leak and pull test to 4 units at shift start up, the end of every shift, the beginning of every job, the end of every job; a new lot of materials/components or equipment adjustment.Quality personnel inspects samples 15 units every 2 hours for the following: tubes are not kinked or coiled too tightly.Tubes shall not have flat spots, or other damage.Parts are free of damage (scuffs, pinch marks, etc.), cracks, crazing, cuts, or other workmanship defects that can affect assembly function or appearance.Leak test is properly performed.Based on the analysis conducted to the sample received, it was observed that the unit had solvent, it could not be attributed to insufficient solving, in addition al the pull test performed in process were acceptable, where is confirmed by sampling performed the lot passes this test.It was not confirmed the root cause that caused this detached, this up to date is an isolated condition reported, it will continue monitoring the mitigations established in process.As such, no corrective and preventive action could have been determined at this time.Smiths medical will continue the investigation and take actions as applicable.Production personnel was notified by quality engineer on 07-mar-2023 as awareness for the failure mode reported by costumer.A device history record (dhr) review was conducted which indicated all inspections were completed and no issues were noted during manufacture.
