(b)(4).When reviewing similar reportable events we have found a number of the complaints with similar fault description (stretcher not closed properly).Taking into consideration that over (b)(4) concertos have been sold 1996, the complaint ratio is considered to be low.From the info obtained via the technician visiting the site, it is indicated the tilting locking mechanism at some point was not working properly, despite there being no issue in closing the stretcher in place it was difficult to open the mechanism as lever needed to be pulled to release it was missing.This means that the concerto/basic device was not up to spec when the event took place.The device was being used for pt handling and in that way contributed to the event.A complete investigation was performed and has identified the following: the stretcher tilting mechanism function of this product, makes it possible and easier to clean the device.The locking mechanism is placed below the stretcher.To tilt the stretcher for cleaning purposes this mechanism has to be unlocked and after the cleaning and before use it should be locked and checked to be locked, as indicated in the instructions for use (ifu).Looking at the incident description we can assume that it is likely that the caregivers made an error in not locking the mechanism, and this directly contributed to the reportable event as later in use the stretcher tilted with a pt on it.The text below is taken from instruction for use (04.Ba.02/5us,ca from 11/2004) which would be delivered this device: "warning: make sure that the catch has locked (click sound) the stretcher after putting it back in place." therefore it appears from our eval that a number of use errors caused the event.The most relevant use error is related with the failure to lock the stretcher in combination with wrong pt position on the device as it is stated in the instruction for use and this directly contributed to the reportable event.We have not been able to find any contributing manufacturing anomalies.The root cause of the complaint was found to be an use error as the received info and our eval as described above are showing that if the ifu safety warnings are followed there will be no pt or caregiver risk.(b)(4).
