ABSTRACT:
Apparatus for selectively blocking passage of lipids in a liquid flow path. A baffle interposed in the liquid flow path is of nonpolar material and is arranged to permit liquid flow therethrough with contact of said liquid with the nonpolar material of the baffle for removing lipids from the flow. In one embodiment, the baffle is interposed between a wound drain connection and vacuum connection in a drain reservoir and protects a hydrophobic filter which is at the end of a vacuum passage communicating with the interior of the drain reservoir. The baffle enables use of a nonpolar material for the hydrophobic filter and avoids coating and thereby clogging of the hydrophobic filter by lipids in the liquid drained from a wound.
