Abstract
In one embodiment, the dressing has a base which is to be adhered to a patient about a catheter site, an aperture in the base to pull a catheter line through and a cover with a window that is folded over and onto the base in a sealed manner. In another embodiment, the dressing has two covers with windows for folding over separate sections of a base to seal in the components of a catheter assembly with multiple catheters extending from a common housing.
Core Innovation
The invention relates to a dressing for a catheter site that includes a base adhered to a patient and a catheter passage structure formed in the base. The base includes an adhesive and an opening for passage of a catheter therethrough from the catheter site, together with a slit extending from the opening to an edge for passage of a catheter line therethrough to the opening. A cover is secured to the base for movement between an opened position spaced from the base and a closed position over the base.
The cover includes a window with a preformed bubble for positioning over and encasing a catheter on the base, and the window has a frame secured about a periphery with an adhesive on an outer surface thereof for securement to the base. In one described configuration, the base is defined by a pair of sections defining an L-shape with the opening disposed in one section and the cover extending from that section. The cover and the base arrangement permits the cover to be closed over the base to provide protection while the catheter is positioned by the window structure.
In additional described configurations, the cover window is a polyurethane of rectangular shape with a preformed bubble, and the base includes a sheet of medical grade polyethylene with a removable silicone release liner disposed over the adhesive. The cover includes a U-shaped polyethylene frame secured to a periphery of the window, with adhesive and a removable silicone release liner disposed over the adhesive of the frame. A further configuration includes a catheter assembly having multiple catheters extending therefrom, with first and second movable covers that provide viewing through windows while each cover is positioned for encasing the catheter line or multiple catheters.
Claims Coverage
The independent claims cover catheter-site dressings with an adhesive base having catheter passage features and movable covers providing window viewing and catheter encasement. Three independent claims are present, each adding specific structural limitations for the base and cover/window features.
Movable cover with framed window and preformed bubble on adhesive base
A dressing comprising a base with adhesive for adhering to a patient; a slit extending from an opening to an edge for passage of catheter line therethrough; an opening for passage of a catheter therethrough from the catheter site; and a cover secured to the base for movement between an opened position spaced from the base and a closed position over the base, the cover having a window with a preformed bubble for positioning over and encasing a catheter on the base and a frame secured about a periphery of the window with an adhesive on an outer surface thereof for securement to the base, the base being defined by a pair of sections defining an L-shape with the opening disposed in one of said sections and with said cover extending from said one section.
Medical-grade polyethylene adhesive base with removable silicone release liner and rectangular polyurethane window cover
A dressing comprising a base including a sheet of medical grade polyethylene with an adhesive on an underside thereof for adhering to a patient and an opening for passage of a catheter therethrough from the catheter site and a removable silicone release liner disposed over said adhesive of said sheet; and a cover having a window of polyurethane of rectangular shape with a preformed bubble for positioning over and encasing a catheter on said base, a U-shaped polyethylene frame secured to a periphery of said window and an adhesive on a surface thereof for securement to said base and a removable silicone release liner disposed over said adhesive of said frame; the cover being secured to said base for movement between an opened position spaced from said base and a closed position over said base.
Two-section L-shaped base with first and second movable covers for single and multiple catheters
A dressing for a catheter site having a catheter assembly with multiple catheters extending therefrom comprising a base having an adhesive on an underside thereof for adhering to a patient; a pair of sections defining an L-shape; an opening in one of said sections for passage of a catheter line of the catheter assembly therethrough from the catheter site; and a slit extending from said opening to an edge of said base for passage of the catheter line therethrough to said opening; a first cover of medical grade plastic secured to said one section of said base for movement between an opened position spaced from said base and a closed position over said base, the first cover having a frame with an adhesive thereon for securement to said base, a window within said frame for viewing said base and the catheter line thereon and a removable release strip over said adhesive of said frame; and a second cover of medical grade plastic secured to another section of said pair of sections of said base for movement between an opened position spaced from said base and a closed position over said base, the second cover having a second frame with an adhesive thereon for securement to said base, a second window within said second frame for viewing said base and a multiple catheters of the catheter assembly thereon and a removable release strip over said adhesive of said second frame.
The claims cover an adhesive catheter-site base with catheter passage openings and slits, paired with movable covers having window structures. The claims further specify window encasement using preformed bubbles, framed adhesive securement, removable silicone release liners or release strips, and, where multiple catheters are present, first and second movable covers associated with different base sections and viewing windows.
