A catheter securement device 1 has a length and width approximately the size of one side of top layer border area DM-2270.
As noted in the figures, a carrier is used to support various layers of an exemplary dressing system 100 of the present disclosure. As shown therein, various layers can have a central area of DM-4305, which is an exemplary thin polyurethane (transparent window) film distributed by Global Biomedical Technologies LLC of Greensboro, GA coated on one side with a low tack pattern coated, medical grade pressure sensitive acrylic adhesive to create a highly breathable, transparent window dressing with the adhesive side of bottom layer facing towards the skin. Said base bottom layers of an exemplary dressing system 100 further comprises a border area of DM-2270, which is a film also distributed by Global Biomedical Technologies LLC of Greensboro, GA consisting of a nonwoven polyurethane fabric coated on one side with a medical grade, pressure sensitive acrylic adhesive blended with a proprietary additive, surrounding the DM-4305. Bottom layer border area DM-2270 is adhered to the periphery of bottom layer central area DM-4305 and skin.
The top layer dressing 130 is similar to bottom layer dressing 120 but larger than bottom layer dressing 120. Top layer dressing 130 has a central area of DM-4305 with an adhesive side facing towards the bottom layer dressing 120 and skin. The central area of top layer dressing 13—DM-4305 completely surrounds the bottom layer dressing 120. Top layer dressing 130 further comprises a border area DM-2270 surrounding top layer DM-4305 central area. Top layer dressing 130 border area DM-2270 is adhered to the periphery of top layer central area DM-4305 and the skin.
The dressing systems of the present disclosure may be applied as one unit design. Both the top layer and bottom layer come pre-assembled on a common carrier covering the adhesive. The top layer may have a removable window frame opposite the carrier to allow the dressing to maintain shape during application. The carrier is cut into three pieces creating two lateral areas and a central area. The central area of the carrier is covering the central area DM-4305 of the bottom layer. The central area of the carrier also covers the bottom layer border area DM-2270 above and below the bottom layer central area DM-4305. The central area of the carrier does not cover the bottom layer border area DM-2270 that is bilateral to bottom layer central area DM-4305. The central area of the carrier also covers the top layer area of DM-4305 and DM-2270 that over hangs above and below the bottom layer. The central area of the carrier does not cover the top layer area of DM-4305 and DM-2270 that over hangs the bottom layer bilaterally. The lateral areas cover the bottom layer border area DM-2270 that is bilateral to bottom layer central area DM-4305 and top layer area of DM-4305 and DM-2270 that over hangs the bottom layer bilaterally.
During application the central carrier area is removed first, allowing the two lateral areas of the carrier to hold the bottom layer onto the top layer and preventing separation during application. The dressing is applied to the wound then the lateral areas of the carrier are removed and the remaining dressing is completely adhered. The window frame is removed last if utilized.
Alternately, the carrier of a dressing of the present disclosure built as one unit may be not be cut allowing it to be removed as one solid piece. The window frame may overhang the top layer bilaterally creating an area to hold on to while applying the dressing system as a single unit.
Another alternate carrier may be cut into two equal pieces. The dressing built as one unit would be applied by partially removing both pieces equally, adhering over the wound before removing the carriers completely and adhering the dressing completely.
Another alternate carrier may be cut into two pieces. A central area carrier covering DM-4305 of bottom layer, DM-2270 of bottom layer, and inner periphery of DM-2270 of top layer. An outer peripheral carrier area can cover the outer periphery of DM-2270 top layer. The outer peripheral carrier area may extend past the outer periphery of DM-2270 top layer. This extension area provides a surface to hold onto (namely a grip portion) while placing the dressing on a patient.
The replacement top layer is the same material and design as the top layer and is different in that it has a carrier covering the adhesive of both DM-2270 and DM-4305 and may also have a removable window frame opposite the carrier to allow the dressing to maintain shape during application. The carrier of the replacement top layer is cut into three pieces creating two lateral areas and a central area. The central area of the replacement top layer carrier is covering the central area DM-4305 of the replacement top layer. The central area of the replacement layer carrier also covers the replacement top layer border area DM-2270 above and below the replacement top layer central area DM-4305. The central area of the replacement top layer carrier does not cover the replacement top layer border area DM-2270 that is bilateral to replacement top layer central area DM-4305. The replacement top layer carrier lateral areas cover the replacement top layer border area DM-2270 that is bilateral to the replacement top layer central area DM-4305. When placing the replacement top layer, the central area carrier is removed. This allows the view of an already in place bottom layer thru the replacement top layer central area DM-4305. The replacement top layer central area DM-4305 acts like and window to visualize the bottom layer border area DM-2270. Bottom layer border area DM-2270 acts like a guide in placing replacement top layer dressing centrally over the bottom layer to prevent replacement top layer border DM-2270 adhesive from contacting bottom layer border area DM-2270. This is important as central area DM-4305 adhesive of top layer and replacement top layer is removable from bottom layer border area DM-2270 top side opposite from the adhesive and bottom layer central area DM-4305 top side opposite from the adhesive. This visualization of the bottom layer border DM-2270 thru replacement top layer central area DM-4305 prevents replacement top layer border DM-2270 from contacting bottom layer border DM-2270 which may cause the dressing to fail during replacement top layer removal from the bottom layer.
Alternately, the replacement top layer carrier may be not be cut allowing it to be removed as one solid piece. The window frame of the replacement layer may overhang the replacement top layer bilaterally creating an area to hold on to while visualizing the bottom layer border DM-2270 thru replacement top layer DM-4305 and applying replacement top layer over a bottom layer and wound.
Another alternate replacement top layer carrier may be cut into two equal pieces. The replacement top layer would be applied by partially removing both carrier pieces equally, visualizing the bottom layer border DM-2270 thru replacement top layer DM-4305 and adhering over the bottom layer and wound before removing the carriers completely and adhering the replacement top layer completely.
Another alternate replacement top layer carrier may be cut into two pieces. A central area carrier covering DM-4305 and onto the inner periphery of DM-2270. An outer peripheral carrier area can cover the outer periphery of DM-2270. The outer peripheral carrier area may extend past the outer periphery of DM-2270. This extension area provides a surface to hold onto (namely a grip portion) while placing the dressing on a patient.
Dressing systems 100 of the present disclosure may be applied in a two-step process in which bottom layer dressing 120 is applied first followed by a replacement top layer dressing 130 as described. The bottom layer dressing 120 may also have a removable window frame opposite the carrier to allow the dressing to maintain shape during application. The bottom layer dressing 120 applied as the first step has a carrier cut into two equal pieces and applied by partially removing both pieces equally, visualizing the wound thru bottom layer central area DM-4305 and adhering over the wound before removing the carriers completely and adhering the bottom layer completely.
Alternatively, the bottom layer dressing 120 carrier may not be cut allowing it to be removed as one solid piece. The window frame of the bottom layer dressing 120 may overhang the bottom layer dressing 120 bilaterally creating an area to hold on to when placing the bottom layer dressing 120 on while visualizing the wound, intravenous device, or pain block catheter thru central area DM-4305.
The dressing system may be referred to as “2VIEW.”
