Abstract

Provided are drainage systems that may include a drainage manifold and may be suitable for draining fluid from a tissue site. The drainage manifold may include a plurality of elongate members having a moveable end that may be adapted to configure the drainage manifold to treat a uniquely shaped tissue site. The drainage manifold may be coupled to a drainage tube with a transitional connector to provide a drainage system capable of distributing reduced pressure to the tissue site to enhance the drainage of fluids.

Core Innovation

An adaptable wound drainage system is described for draining fluid from a tissue site using a drainage manifold coupled to a transitional connector and a drainage tube that provides fluid communication to the manifold. The system uses a reduced-pressure source connected to the drainage tube and an optional fluid canister in the drainage path.

The drainage manifold includes an elongate support positioned on a longitudinal axis and a plurality of elongate members having an oblong cross-sectional shape. Each elongate member has a first end that is moveable between a gathered position and a dispersed position relative to the longitudinal axis, where in the gathered position the elongate members are releasably secured longitudinally and circumferentially about the external surface of the elongate support.

Each elongate member comprises an opening disposed through an outer wall providing fluid communication between an inner lumen of the elongate member and the outer wall, and a longitudinal duct positioned on the outer wall between the first end and the second end. The elongate member further includes a reinforced portion positioned between the first end and the second end, with variants including sacrificial webs releasably securing gathered members to the elongate support.

The drainage manifold is further described with features for maintaining fluid communication under reduced pressure, reducing fluid pooling associated with seroma and hematoma, and mitigating pain during withdrawal. The transitional connector geometry includes tapering and an optional circular cross-section, and the system includes features for defining longitudinal grooves and central lumens.

Claims Coverage

The independent claims define a drainage system and a drainage manifold, together covering an adaptable manifold with oblong, moveable elongate members and fluid-communication structures, including a transitional connector and reduced-pressure drainage path features. Across the independent claims, the main inventive features include the gathered-to-dispersed moveability with releasable securement about an elongate support, the oblong elongate member structure with longitudinal duct and openings for fluid communication, and the coupling to a drainage tube via a transitional connector, with an additional independent-manifold claim adding sacrificial webs for releasable securement.

The independent claim set centers on an adaptable drainage manifold using oblong elongate members whose first ends move between gathered and dispersed positions, with releasable securement about an elongate support, and with longitudinal duct plus outer-wall openings that provide fluid communication from the elongate-member inner lumens. The drainage system couples the manifold to a drainage tube via a transitional connector, while the separate independent-manifold claim further specifies sacrificial webs between the elongate member and the elongate support to enable the gathered-position securement.
