Abstract: An irrigation basin is disclosed for retaining waste fluids, having a support surface and a trough. The support surface is designed so that a patient can rest a head or extremity, such as a hand or foot, on the surface, while medical personnel flush the head or extremity with fluid or drain wounds found in the body part. The waste fluids are retained by the trough around the support surface. The irrigation basin is also useful for washing the hair of injured or immobile patients, and may further function as an emesis basin. In a preferred embodiment, the support surface slopes to drain fluid into the trough. The support surface can be concave to help cradle the head or other body part. The support surface can also be lower than the outside wall of the trough to minimize fluid splashes outside of the basin. Ribs can be provided in the walls of the basin to increase basin strength and prevent sliding when multiple basins are stacked.
