The first surface of the substrate is affixed to a removable release pad that completely covers the first surface area of the substrate. Further, a pull tab is provided that is part of the release liner and is located in the cutout of the skirt of the substrate such that a peel force can be transferred from the release liner to the housing at the location where the cutout reaches the housing. 一种贴片式注射装置，包括壳体，粘合基底，粘合基底具有带有用于皮肤贴附的第一表面区域的第一表面，以及部分地贴附到壳体的与第一表面相对的第二表面，以及可移除释放衬垫。贴附到壳体的第二表面的表面区域小于第一表面区域，并且多余的区域限定至少部分地围绕壳体的基底的裙部。基底的第一表面贴附到完全覆盖基底的第一表面区域的可移除释放衬垫。此外，提供拉片，其为释放衬垫的一部分并且位于基底的
