(b)(4).Result of examination: the received sample was subjected to a visual and functional examination.The operating unit was already changed.However, the original operating unit was received in addition for investigation.The sample was found heavily contaminated.The device had previously been opened before submitting for investigation, because the cover caps were not available.The history log files showed different device alarms 1113, 1024 and 1105.For the performed long term test, the attached operating unit was mounted to the device.The test revealed no abnormalities nor any device alarms.The perfusor space showed inside several damages caused by fluid as well as the attached operating unit.There we found the contacts to be oxidized.The sample must have been exposed to a heavy amount of fluid out of its specification.Due to the penetrated fluid the device alarmed (1024 and 1105).The result was that the operating unit could not longer operate.In this case the syringe has to be removed from the pump, by the emergency release button.The device was subjected to wrong handling.Following is described in the ifu: · prior to administration, visibly inspect the pump and the accessories (especially the axial fixation) for damage, missing parts or contamination and check audible and visible alarms during selftest.· protect the device and the power supply against moisture.
