(b)(4).It was reported that during the transfer from room to bath, the patient and the chair fell over the caregiver due to the breakage of the part linking the chair to the steering column.No injury caused for the patient.The device was inspected by an arjohuntleigh representative at the customer site and found to be out of its specification.We do not appear to have any other complaint with similar failure.It is considered as an isolated case.The received serial number showed that device was being used by 13 years what is 3 years outside its operational life time, and this way the device could contribute to the event.Instruction for use - ifu (operating and daily maintenance instruction 04.Cd.02/6 gb from april 2000) active at the time of the manufacturing.Is provided with each device.It includes information about safe and correct use of the product.It informs in foreword: "the useful life of this equipment, unless otherwise stated is ten (10) years, subject to preventative maintenance being carried out in accordance with the instructions for care and maintenance." ifu provides also safety instructions: "warning: do not overload the lift hygiene chair! it has a lifting capacity of 160kg." "warning! don't overload the scale.Remove the load immediately, when the max-symbol is on." despite many requests for return neither parts nor the device was returned to the manufacturer for further evaluation.Parts could not be evaluated by the manufacturer and no conclusions could be made.Therefore, the exact root cause of the breakage could not be established.The photographic evidence was provided which confirms reported detachment.From the pictures we can only suspect that the reason for the load cell breakage is overloading and lack of proper maintenance.From above findings and fact that we do not appear to have any similar complaints we conclude that this incident was caused by user error - e.G.: using the device after recommended operational lifetime.The received information and our evaluation as described above are showing that if alenti's safety instructions were followed in accordance to ifu, there would be no user at risk.
