The unit was returned and was tested using our standard operating procedures.Upon receipt, it was determined that the membrane switch intermittently shorted due to saline and blood contamination on the display.In addition, it was also noted upon receipt that the pole clamp release handle was missing, it was evident that the unit had been opened by the customer, and there appeared to be a dent on the membrane switch.As fluid contamination may damage internal components, the service and preventive maintenance schedule outlined in the operator's manual instructs the user to check the unit seals every six months.The manual provides the following cleaning instructions: "inspect the seal around the unit to make certain it is in good condition.Check also the seal around the touch screen and ceramic disks.Use dow corning 732 multipurpose rtv sealant or equivalent if needed to maintain fluid resistance." the manufacturing records for this serial number were reviewed and nothing notable was indicated.The unit had not been returned to belmont since it was initially shipped to the customer in 2016.There was no patient injury reported.Should additional information become available, a supplemental report will be submitted accordingly.
