During the set-up of the cellex photopheresis kit, it was noted the drive tube was not tightly fitting the centrifuge bowl brackets.The tubing was sliding up and down.When the drive tube is not tightly secured in the brackets and as the procedure starts, the centrifugal force used for the procedure may cause the drive tube to break inside the centrifuge compartment, therefore resulting in patient's blood loss.The patient was not connected to the device.The defect was noted during the installation of the kit.
