ABSTRACT:
A basin adapted to receive and contain a fluid draining from an irrigated wound or abscess on a portion of a person's body. The basin is anatomically contoured and dimensioned to permit a fluid tight seal between the person's skin and the basin when a potion of the rim of the basin is in juxtaposition with a variety of contoured portions of the body such as the trunk, arm head, finger, neck, and the like. The basin consists of a bowl-like container having unitary construction and having a flat, substantially planar bottom portion. The perimeter of the bottom portion is trilobate, having a plurality of convex curves or lobes around the outer periphery thereof. The lobes are convex, projecting generally outward from the center of the bottom portion, each lobe having a different radius of curvature than the other lobes. The bottom portion of the basin is bounded by a smooth continuous wall projecting upward and slightly outward from the periphery of the bottom portion. Near the superior aspect or top of the wall, the wall curves gracefully outward and upward to form a peripheral rim flange around the top of the basin. The width or lateral extension of the rim flange varies along the periphery of the rim and provides means for holding the basin without exposing fingers to the content of the basin. The outermost edge of the rim flange is shaped to direct the flow of a fluid spilled thereon into the basin under the force of gravity rather than away from the basin as occurs with prior art basins having a recurved rim flange. The basin, which is multi-contoured to adapt to a variety of anatomical topographies, presents an overall shape operable for enabling the nested stacking of a number of such units to reduce storage space.
