Abstract
A catheter securement bandage may include a base layer formed with a multi-ply laminate comprising adhesive, gauze, and plastic layers. A top layer may similarly be formed with a multi-ply laminate comprising a layer adhesive, plastic, gauze, and an added layer of adhesive. By securing a hub portion and lure connector of a catheter, the catheter securement bandage maintains an optimal catheter insertion angle of the catheter into a patent this preventing kinking and obstruction of flow through the catheter.
Core Innovation
The disclosed invention provides a peripheral intravenous and arterial catheter securement device that includes a base layer formed with a multi-ply laminate comprising a first layer of adhesive, a second layer of gauze, and a third layer of plastic. The device further includes a first release liner protecting at least a portion of the adhesive on the base layer and a second release liner protecting at least an additional portion of the adhesive on the base layer. A top layer is formed with a multi-ply laminate comprising a first layer of adhesive, a second layer of gauze, and a third layer of plastic, with the first layer of adhesive on the top layer securing to the third layer of plastic on the base layer.
The top layer includes a first adhesive tab configured to attach to a hub portion of a catheter with an adhesive and a second adhesive tab configured to attach to a luer connector with an adhesive. The first adhesive tab and the second adhesive tab each includes a free-floating end not attached to the base layer. The first release liner and the second release liner only partially contact the first layer of adhesive on the base layer, and each includes a length greater than a length of the base layer.
The device is described as a securement bandage that secures the catheter hub and luer connector while maintaining an inclined catheter insertion angle to reduce catheter bending, kinking, and obstruction of flow. It provides wrap-around, suture-free stabilization and skin protection, and is described as improving performance as compared with tape/transparent dressings and hook-and-loop concepts.
Claims Coverage
The partial content identifies one independent claim, which covers the overall securement device architecture including multi-ply base and top laminates, two release liners, and a top layer with first and second adhesive tabs having free-floating ends. The dependent claims further narrow details of liner contact, a perforation dividing the tabs, and an inclined-angle securing arrangement for catheter insertion.
Multi-ply base layer with paired release liners
A base layer formed with a multi-ply laminate comprising a first layer of adhesive, a second layer of gauze, and a third layer of plastic; a first release liner protecting at least a portion of the adhesive on the base layer; and a second release liner protecting at least an additional portion of the adhesive on the base layer.
Multi-ply top layer with secured adhesive-to-plastic lamination
A top layer formed with a multi-ply laminate comprising a first layer of adhesive, a second layer of gauze, and a third layer of plastic wherein the first layer of adhesive on the top layer secures to the third layer of plastic on the base layer.
First and second adhesive tabs with free-floating ends
The top layer comprising a first adhesive tab configured to attach to a hub portion of a catheter with an adhesive and a second adhesive tab configured to attach to a luer connector with an adhesive, wherein each tab includes a free-floating end not attached to the base layer.
Partially contacting release liners with lengths greater than the base layer
The first release liner and the second release liner only partially contact the first layer of adhesive on the base layer, and each includes a length greater than a length of the base layer.
Overall, the claim coverage focuses on a catheter securement device built from a multi-ply base laminate with first and second release liners and a multi-ply top laminate that forms two adhesive tabs with free-floating ends. The dependent claims further specify liner unattached portions, a perforation dividing the top layer into the first and second adhesive tabs, and an inclined-angle securing arrangement for catheter insertion at the patient entry point.
Stated Advantages
Maintains an inclined catheter insertion angle to reduce catheter bending, kinking, and obstruction of flow.
Provides wrap-around, suture-free stabilization and skin protection.
Provides improved performance as compared with tape/transparent dressings and hook-and-loop concepts.
Documented Applications
Peripheral intravenous catheter securement, including securing a catheter hub portion and maintaining an inclined catheter insertion angle at a patient entry point.
Arterial catheter securement, including securing a catheter hub portion and a luer connector while maintaining an inclined catheter insertion angle to reduce catheter bending, kinking, and obstruction of flow.
