A hospital-grade basin holds water for washing patients, or alternatively converts easily / quickly for a patient's limb to rest comfortably within and across a portion of the basin. In a first embodiment, half-moon shaped openings on opposite sides of the basin side walks) comfortably support the limb at a reduced height with respect to adjacent side wall portions, which serve as a partial shield during wound irrigation, and aid fluid collection. The shaped openings may each be sealed with a hinged door in a closed position, using a friction fit, to form the traditional, watertight basin. In an alternate embodiment, the doors may be secured in the closed position using an elastomeric leaf-spring-shaped member. In other embodiments, rather than cutouts and doors, opposing portions of the side wall may instead be formed of an over-molded elastomeric material that conforms to the patient's limb, or may instead be formed like a bellows.

A splashback shield for attachment to a syringe for wound irrigation includes a generally dome-shaped shield with a conduit or tunnel through the top that narrows to form a nozzle as it extends substantially inside the shield. A number of air vents or passageways surround the conduit so when submerging and re-filling the syringe with irrigant with the shield attached any air trapped inside the shield escapes rather than drawn into the syringe. The air vents are preferably elongate tubular passageways that narrow exiting the shield, facilitating air escaping but the irrigant mixed with any blood and contamination tends not to pass through the vents. The device is an improvement over the conventional Zerowet® Splashield® product.
