A portable medical apparatus for supporting a patient's arm having a top surface, a bottom surface, a peripheral surface, and an outer layer. The top surface has a front edge and a back edge opposite the front edge. The top surface defines a concave depression that extends into the top surface and slopes downward from the back edge to the front edge. The bottom surface is opposite the top surface. The peripheral surface connects the top surface to the bottom surface. The outer layer is connected to a portion of the peripheral surface and defines a pocket between the outer layer and the portion of the peripheral surface. The pocket has an opening adjacent to the top surface.
