Event Description
|
On (b)(6) 2017, the following information was provided to kci by the central supply representative: the v.A.C.Freedom¿ therapy (system) was allegedly sparking and smoking with no injuries to the patient or staff.On (b)(6) 2017, the device was tested per quality control (qc) procedure by kci field service, and the unit passed the qc checks and met specifications.On (b)(6) 2017, the device was placed with the patient.On (b)(6) 2017, kci quality engineering determined the device revealed evidence of thermal damage to the data port assembly via external inspection.Further evaluation found evidence of a foreign substance could be seen on the device housing, in the data port assembly, and within the data port protective cover.Internal inspection of the device revealed the foreign substance within the device as well.There was also thermal damage to the insulation of the data port wires, which exposed the electrical conductors.The composition and source of the foreign substance could not be determined; however it is consistent with fluid ingress.The device was reassembled and plugged into the original power cords.The device immediately produced a burnt odor and smoke began to emit from the data port connection.The device would not power up on battery power or when plugged in.Functional testing could not be performed.The returned power cords were found to be in good condition and to function properly.
