Event Description
|
This case was reviewed and investigated according to the manufacturer's policy.An internal review of similar complaint descriptions reported under mdr 2939520-2018-00023 prompted a re-investigation of the returned device as a potential similar complaint.On 05/07/2018, the manufactures sr.Manufacturing engineer, was requested to assist with the evaluation of the manufactures device bedside utility box (bub).Visual inspection of the returned bub was performed.No external physical damage was observed.The bub cover was removed to disassemble for a careful internal examination.No burnt smell was detected before or after disassembling the device.Discoloration and damage was noticed on the capacitor (c94) that is located on an internal board inside the manufactures device.According, to the inspection of the failed bub, the capacitor c94 appeared discolored due to excessive heat due to the capacitor failing.Measuring continuity of tp23 and tp21 to ground using multimeter, it was found that the 12v output is shorted.The circuit is designed to not supply power if a short is detected.The ao/ecg twin-ax cable connector requires 12v to power on, so this confirms that the failure was caused by the failed capacitor inside of the bub.This malfunction is being reported because a reinvestigation of the device found the capacitor had shorted and appeared discolored due to excessive heat.There is a potential for harm if the malfunction were to recur.

Event Description

This follow-up supplemental report #1 is being submitted to report additional investigation findings, to wit: there is no potential for harm if the malfunction were to recur.The investigation performed for this case indicates that an electrical component (capacitor c95) was damaged and discolored due to a short circuit which generated excessive heat.The manufacture's device is designed and tested to be in compliance with iec 60601-1 2005 edition, sub clause 11.2 - fire prevention and 11.3 - constructional requirements for fire enclosures of me equipment.Therefore, in the presence of a shorted capacitor within the manufacture's device, based on the design and specification of the manufacture's device, and further validated by safety testing and associated certification, such a fault condition would not result in being a source of ignition in the environment of intended use resulting in an explosion or fire.Potential consequences to the patients and hospital staff for this incident and if this incident were to recur would be to abandon use of manufacture's device technology due to no signal.This case was reviewed and investigated according to the manufacturer's policy.(b)(4).
