The reported event was confirmed as use related based on the sample evaluation and ifu.Visual evaluation noted a round silicone channel drain attached to tubing.The drain end was submerged in water and tubing connected to an in-house 3 spring evacuator.The evacuator was compressed and outlet port closed.The evacuator suctioned no water.The drain was disconnected and evacuator tested without it to ensure evacuator functioned with no issues.The drain was dissected to identify what appeared to be dried blood and/or human tissue clogging all 4 of the channels.The lot number is unknown; therefore, the device history record could not be reviewed.The instructions for use were found adequate and state the following: "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.".
