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 the wound drain connection and vacuum connection in a drain reservoir and protects the hydrophobic filter which is at the end of the vacuum passage communicating with the interior of the drain reservoir bottle. 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.

A continuous vacuum wound drainage system, comprising a base unit and a drain reservoir releasably secured to the base unit for partial evacuation to a subatmospheric pressure; wound connection means for connecting said drain reservoir to a wound and therewith for vacuum draining fluids from said wound; said base unit having a housing in turn having a forward facing groove which opens upward and is shaped and sized so that said drain reservoir is downwardly receivable in said groove, said base unit including control means and a power switch actuable for energizing said control means and a motorized vacuum pump actuable by said control means unit upon enabling of the latter by actuation of said power switch; said drain reservoir comprising a hollow upward opening bottle closed by a fixed cover, one end of said cover overhanging the side of said bottle; telescoping recess and leg means on said overhanging cover and the top of said base unit adjacent said groove, said telescoping recess and leg means being aligned substantially vertically for entering telescoped relation upon downward insertion of said drain reservoir into said groove in said base unit, said recess and leg means including an actuator for said power switch on said base unit and surface means on said cover overhanging end for actuating said power switch actuator in response to establishing of said telescoped condition of said recess and leg means due to insertion of said drainage receptacle and drain reservoir in said groove of said base unit.
