The reported event was unconfirmed since the reported failure could not be reproduced.Visual evaluation of the returned sample noted one opened (without original packaging), reliaivac evacuator.Visual inspection of the sample noted no obvious visible defects.Concomitant, in-house evacuator tubing was attached to port a of the evacuator and used to suction in methylene blue solution (3 drops 1% aq methylene blue per 100ml distilled water).The balloon fully inflated with no difficulty and port b was closed off to create negative pressure.The device was able to successfully suction 400cc of solution and expel without issue.This meets the acceptance criteria.A device history record review was not required per the investigation.The instructions for use were found adequate and state the following: "10.Attaching to auxiliary suction: 10.I.) insert suction adapter into outlet port.10.Ii.) attach wall suction tubing to suction adapter.10.Iii.) during auxiliary suction, balloon will inflate and exudates will flow over balloon surface.10.Iv.) to discontinue auxiliary suction, remove suction adapter and close outlet port.Note: do not use with wall suction in excess of 210mm hg.11.To establish suction: 11.I.) open outlet port.11.Ii.) pump bulb until balloon fills container.11.Iii.) close outlet port.Note: hissing sound is normal and stops when maximum suction pressure is reached.Possible reflux of fluid to the patient is reduced during reliavac® evacuator reactivation by a built-in anti-reflux valve in the inlet port.12.To empty container: 12.I.) open outlet port.12.Ii.) invert unit.12.Iii.) pump bulb to empty quickly.13.To re-establish suction: - repeat step ¿11¿ above.Note: reflux of fluid to the patient is minimized during reactivation by a built-in anti-reflux valve on inlet port.14.To read fluid volume: 14.I.) open outlet port.14.Ii.) allow balloon to deflate.14.Iii.) read volume.Important: a.Check for fluid entering reliavac® evacuator.Lack of flow may indicate the following: i.All exudates have been removed.Ii.Wound drain is clogged and may require irrigation & aspiration (consult physician).Iii.Auxiliary wall suction pressure is above 210 mm hg.Iv.Deflated balloon: check all connections for air leak and drain perforations for exposure above the skin and follow step ¿11¿ above.If still deflated, replace the evacuator.B.When not using auxiliary suction during surgical wound closure, several activations of the reliavac® evacuator may be required to establish suction because of the following: i.Air entering partially closed wound.Ii.An operative air pocket." h11:section a through f - the information provided by bd represents all of the known information at this time.Despite good faith efforts to obtain additional information, the complainant / reporter was unable or unwilling to provide any further patient, product, or procedural details to bd.
