(b)(4).When receiving similar reportable events for system 2000 we have similar cases.We have been able to establish that there is a very low complaint rate relating to this kind of event-tub was tipping during use.With the amount of sold devices (arjohuntleigh manufactured over (b)(4) system 2000 baths to date) and in comparison to the daily use of them the ratio observed for complaints with this failure mode is considered to be very low and acceptable.The device was inspected by an arjohuntleigh rep at the customer site and found to be out of specification- base cover off, however, this failure couldn't contribute to reported incident.The device was being used for patient handling and in that way contributed to the event.No injury to the patient occurred.Patient was positioned on hygienic chair.Please note also that info provided by arjohuntleigh rep that contacted and visited the customer site showed that it was not possible to re-create this event and possibility of this event was called into question.From the above findings we come to conclude that this incident was caused by user error- user didn't follow recommended device handling procedures and warnings included in instructions for use.It is not likely that tube would have tipped if recommended procedures included in operation and product care instructions were followed, as proved by our test reports.We have not been able to find any contributing mfg anomalies.
