Investigation summary: one sample was provided to our quality team for investigation.A device history review was performed and found no non-conformances associated with this issue during the production of this batch.The final product for lot ta10414 is assembled and packaged at a supplier site.We provided the product sample to the supplier for evaluation and they were able to verify the product was outside the blister pack which resulted in improper sealing of the blister package.The set is manually assembled and inserted into the machine, which seals the paper to form the unit packaging.Through their investigation it was determined that this issue likely occurred as a result of improper placement of the device into the blister machine by the operator which led to poor sealing of the blister pack.Improvements have been made on the blister machine to avoid reoccurrence of this issue, the reported lot was manufactured prior to these improvements being implemented.Complaints for this device and defect will continue to be monitored by our quality team for signs of emerging trends.Machine is considered as one of the sources of the problem reported by the customer at the issue is generated during the unitary packaging of the set into the blister machine.Manpower is considered at the root cause of the problem according to the available information.The operator placed incorrectly the set into the blister machine, result of a punctual operator´s carelessness due to the mold design related to the cavity.Conclusion: after the investigation, it is concluded that the most probably root cause is that the cavity of the mold is not suitable enough to support long sets, like iv sets and/or extension set and then, the operator has more difficult the manual task of introduce the set into the cavity.Capa is not required in this instance as an internal capa has already been implemented (capa-2018/055) and the blister machine has already been modified to include specific moulds for each type of product (the mould for phaseal products began to be used in the middle of january), in such a way that it avoids the equipment being trapped when it comes to sealing the blister.In this way, it avoids breakages in the equipment by not being trapped and ensures the correct welding of the blister.
