Event or Problem Description
Arjo became aware of the nimbus 4 mattress over-inflation.The malfunction was observed by the customer¿s maintenance technician during preparing the mattress for use.No patient was involved and no injury occurred.When the failure occurred, the field safety corrective action was not completed on the involved product.The mattress was taken out of use and quarantined.
Additional Manufacturer Narrative
The cause of the automatt overinflation is the incorrect circulation of the air in the automatt sensor pad (mattress base) due to a damaged inner tube.The tpu (thermoplastic polyurethane) tube may break over time due to the extruding force of the silicone tube and the external bending force, causing air accumulation in automatt.In summary, the nimbus 4 mattress did not meet its specification since the automatt sensor pad was faulty.No patient was involved when the reported issue occurred.No injury was claimed.The complaint was decided to be reportable due to the risk of patient¿s fall because the mattress was not corrected as per the field safety corrective action ( fsn-suz-001-2021).
