The device was received for evaluation.Visual inspection revealed all the pump segments are disconnected from the support plate.There are no marks of solvent on the tubing.The reported condition was verified.During evaluation, it was noted the involved pump segments of tubing were not bonded to the support plates of the prismaflex set and showed very little to no trace of solvent used to achieve this bonding which is the cause of the event.The pump segment of tubing could remain in place in the sockets on the support place due to the friction between the tubing and the socket since the outer diameter of the tubing is of similar size as the socket.This allowed the defect to remain undetected at the integrity test performed on each set during assembly.However, this friction is not enough for the pump segment of tubing to remain connected to the support plate once the set is loaded on a prismaflex or prismax monitor, and the monitor¿s pump rotors apply pressure on the tubing.A nonconformance has been opened to address this issue.A batch review was conducted and there were no deviations found related to this reported condition during the manufacture of this lot.Should additional relevant information become available, a supplemental report will be submitted.
