The device history record was reviewed and indicated that the product was released accomplishing all quality standards.Few samples were received for the evaluation.Upon visual evaluation, all the sponges had radiopaque element adhered to the sponges.However, there was a piece of element that was loose from the rest of the sponges.Therefore, the reported condition is confirmed.The possible root cause could be during the element application process if when the element traverses around the pressure roller, heated roller, and bonding wheel that the element does not adhere properly, then the element can have the opportunity to become loose within the folds of the sponge.However, with the way the sponges are folded reduces the chance of the element from falling out throughout a procedure.Another possible root cause could be that during this process the element could have burnt in pieces and was caught between the sponges.The sample sponge will be sent to the production for quality awareness.As a preventive action, if the element has been in pieces, the sensors on the machine will shut down the machine, until the issue has been fixed and the defective sponges before the machine shutdown will be inspected.Regular inspections are performed based on the statistical sampling both physically and visually.Specifically, operators are required to inspect the samples at the beginning, middle and end of the lot production.These checks are noted on the device history record.
