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
The invention is directed to a drainage system for draining fluid from a tissue site that includes a drainage tube and a drainage manifold attached to the drainage tube. The drainage manifold includes a plurality of members, where each member includes a lumen, an outer wall, and an opening disposed through the outer wall. At least one web is configured to hold the plurality of members in a gathered position such that the plurality of members are adjacent each other, with the opening and the web extending over a common length of each member.
Moving the plurality of members from the gathered position to a dispersed position, such that the plurality of members are further apart from each other than in the gathered position, causes the at least one web to sever. In some embodiments, the opening is a single longitudinal channel extending along a longitudinal surface of each member, and the web structure includes longitudinal extent and/or score or perforation to guide severing.
The drainage manifold is coupled to a drainage tube via a transitional connector having a first end and an opposing second end, where the first end is coupled to the drainage manifold and the second end is coupled to the drainage tube such that the drainage tube is in fluid communication with the lumen of each member. Further embodiments include a reduced-pressure source and a fluid canister positioned in fluid communication between the drainage tube and the reduced-pressure source, where the fluid canister is configured to retain fluid communication with the drainage manifold.
Claims Coverage
The independent claims cover four related features: a manifold with severable web behavior when switching from gathered to dispersed positions, manifold-to-tube coupling using a transitional connector for lumen fluid communication, inclusion of a reduced-pressure source and a fluid canister for fluid communication, and a drainage manifold geometry where each member has only one opening consisting of a single longitudinal channel. The main inventive feature is that movement from gathered to dispersed positions causes the at least one web to sever.
Severable web that transitions manifold from gathered to dispersed positions
A drainage system comprising a drainage tube and a drainage manifold attached to the drainage tube, where a plurality of members each include a lumen, an outer wall, and an opening disposed through the outer wall, and at least one web holds the plurality of members in a gathered position such that the plurality of members are adjacent each other; moving the plurality of members from the gathered position to a dispersed position such that the plurality of members are further apart causes the at least one web to sever.
Transitional connector providing fluid communication between drainage tube and manifold lumens
A drainage system comprising a drainage tube and a drainage manifold attached to the drainage tube including a plurality of members with a lumen, an outer wall, and an opening disposed through the outer wall, at least one web holding the plurality of members in a gathered position, and a transitional connector having a first end and an opposing second end; the first end coupled to the drainage manifold and the drainage tube coupled to the second end of the transitional connector such that the drainage tube is in fluid communication with the lumen of each member, wherein moving the plurality of members from the gathered position to a dispersed position causes the at least one web to sever.
Reduced-pressure source and fluid canister retaining fluid communication
A drainage system comprising a drainage tube and a drainage manifold attached to the drainage tube including a plurality of members with a lumen, an outer wall, and an opening disposed through the outer wall, at least one web holding the plurality of members in a gathered position, a reduced-pressure source, and a fluid canister positioned in fluid communication between the drainage tube and the reduced-pressure source, wherein the fluid canister is configured to retain fluid communication with the drainage manifold, wherein moving the plurality of members from the gathered position to a dispersed position causes the at least one web to sever.
Single longitudinal channel opening per member and severing upon dispersion
A drainage manifold comprising a plurality of members, each member comprising a lumen, an outer wall, and only one opening disposed through the outer wall, the opening consisting of a single longitudinal channel that extends along a longitudinal surface of each member, and at least one web configured to hold the plurality of members in a gathered position such that the plurality of members are adjacent each other; wherein moving the plurality of members from the gathered position to a dispersed position such that the plurality of members are further apart causes the at least one web to sever.
Across the independent claims, the core claim coverage focuses on a drainage manifold whose members are held adjacent in a gathered position by at least one web, where switching to a dispersed position severs the web, and where fluid communication is defined via manifold lumens and optional coupling structures and reduced-pressure components.
