Abstract

A fluidic connection system includes a membrane with an inner contact surface, an outer surface, and a pair of cover panels with perimeters, interior portions and edge strips. The panels are joined together at a seam extending transversely along their edge strips. A tube opening extends between the edge strips and is open at the membrane inner and outer surfaces. A tube or sheath includes a proximate end extending through the tube opening and terminating at the membrane inner surface and a distal end terminating in spaced relation from the membrane outer surface. Adhesive is applied to the membrane inner contact surface for releasably fastening the membrane on a patient'"'"'s skin. The system can be utilized as a wound dressing for draining wound exudate and for introducing liquid, e.g. growth factors and antibiotics, to the wound site. The membrane can comprise a semi-permeable material. In one embodiment the tube proximate end includes a side opening and extends through the membrane tube opening for placement adjacent to an inner skin contact surface. In another embodiment the tube proximate end is split to form a pair of opposed tabs, each of which is attached to a membrane panel. The tabs form a proximate end opening or mouth of the tube. The membrane panels can be adhesively secured to a patient'"'"'s penis for using the system as a condom catheter.
