It was alleged that a patient experienced a burn while using a mul-t-pad with an associated tp700 device.The model and lot number of the pad used was not specified by the user facility.The user facility identified that the patient received a few small water blisters about the size of a pea of their back.The patients son stated that the patient had sensitive skin which may be a contributing factor to the issue.An allevyn dressing was used for protection, however, no medication was applied and the patient was discharged the same day.The associated t-pump was allegedly tested and passed the operating temperature test.A review of the information associated with this event, identified that unless there was a specific device malfunction, the burn was likely misidentified.For a burn to occur, the device would need to be at least 44° c.Without a failure of the backup and primary thermostats, the highest temperature the t-pump can reach is 42° c.As there must be a failure of both the backup limit thermostat and the primary thermostat (operating temperature test) in order to achieve a temperature of 44° c that would allow for a burn to occur, it is most likely that the patient experienced a soft tissue injury from the mul-t-pad that was being used.This can be attributed to mechanical forces (such as pressure or sheer) created by the pad.The device could not be identified.
