Affected devices: aquilex fluid control system consisting of pump: aql-100p: (b)(4).Scale: aql-100cs: (b)(4).Patient harm was not reported.In general, the description of the event is very poor.As no statement was made about the extent of the deficit problems and no queries were answered nor were the units sent in for examination, a malfunction that could fulfil the reporting criteria cannot be completely ruled out at present.Further attempts will be made to obtain more information about the complaint situation and to retrieve the units from the complainant.A follow-up report will be submitted.

The reported event could be not confirmed.There are no indications of a manufacturing issue.The returned device showed severe signs of mishandling, but the functional tests were passed.The complaint scenario could not be confirmed, and a malfunction was excluded.Additional reasons why the deficit displayed by the pump does not correspond to the expected deficit, include uterine perforation, non-return of irrigation fluid to the waste containers, so the system cannot calculate the deficit (e.G.Fluid remaining on the floor, doctor's clothing or under-buttocks-drape; use of additional suction system with its own collection containers), or wrong manual determination of the deficit.The most possible root cause is one of the aforementioned device-independent issues.
