Abstract
A window dressing includes a primary layer having a window for viewing a catheter insertions site. The primary layer includes an adhesive layer on a lower, skin-contacting face of the primary layer. A transparent layer covers the window and adheres to the patients skin and to the top surface of the primary layer. A support structure has a stiffness that is greater than the primary layer and has an adhesive layer on the lower surface of a structural layer of the support structure. The support structure adhesive layer adheres to the support structure to the top surface of the primary layer.
Claims20
A window dressing comprising:
- a primary layer having a lower, skin-facing surface and an upper surface, the primary layer having a first stiffness and comprising a window portion having a window formed therein and a securement portion;
- a primary adhesive layer covering at least a portion of the lower, skin-facing surface of the primary layer;
- a support structure attached to the upper surface of the primary layer, the support structure comprising:
- a structural layer having a lower surface and an upper surface, the structural layer having a second stiffness that is greater than the first stiffness, and
- an adhesive layer covering at least a portion of the lower surface of the structural layer and adhering the structural layer to the top surface of the primary layer;
- a central region covering a catheter tube over a tube covering distance when the window dressing is applied to a patient;
- and
- a plurality of arms, each arm extending from the central region in both lateral and longitudinal directions, wherein the tube covering distance is greater than a thickness of each arm;
- and
- a transparent layer attached to the upper surface of the primary layer and covering at least a portion of the primary layer window, the transparent layer comprising:
- a transparent film having a lower surface and an upper surface, and
- an adhesive layer covering at least a portion of the lower surface of the transparent film and adhering a first portion of the transparent layer to the upper surface of the primary layer and a second portion of the transparent layer to the upper surface of the structural layer.
A window dressing comprising:
- a primary layer having a lower, skin-facing surface and an upper surface, the primary layer having a first stiffness and comprising a window portion having a window formed therein and a securement portion;
- a primary adhesive layer covering at least a portion of the lower, skin-facing surface of the primary layer;
- a support structure attached to the upper surface of the primary layer, the support structure comprising:
- a structural layer having a lower surface and an upper surface, the structural layer having a second stiffness that is greater than the first stiffness, and
- an adhesive layer covering at least a portion of the lower surface of the structural layer and adhering the structural layer to the top surface of the primary layer;
- a central region covering a catheter tube over a tube covering distance when the window dressing is applied to a patient;
- and
- a first arm and a second arm, each arm extending from the central region in both lateral and longitudinal directions, wherein the arms converge at a point that aligns with a centerline of the dressing;
- and
- a transparent layer attached to the upper surface of the primary layer and covering at least a portion of the primary layer window, the transparent layer comprising:
- a transparent film having a lower surface and an upper surface, and
- an adhesive layer covering at least a portion of the lower surface of the transparent film and adhering a first portion of the transparent layer to the upper surface of the primary layer and a second portion of the transparent layer to the upper surface of the structural layer.
