CONFORMABLE MEDICAL DRESSING WITH SELF SUPPORTING SUBSTRATE
FIG4B is a top plan view of another exemplary embodiment of a medical dressing prior to the addition of a self supporting substrate
The linear cut 31 can provide a tab 33 that creates a beginning point at which the carrier 27 may be easily lifted from backing 14 and peeled. Although cut 31 may also be a nonlinear cut which is known in the art, the preferred embodiment includes a linear cut. Linear cuts form a more distinct tab 33 to facilitate removal of the carrier 27. Tab 33 can also be formed away from the linear cut 31 as a shape in carrier 27, as shown in FIG4B.
