Abstract
Abstract An instrument tray and basin for use in soaking, rinsing, and draining urological instruments and other instruments prior to use, and for supporting such instruments during transit and storage. The plastic tray is generally rectangular and compartmented, and has openings or perforations through its bottom wall. The basin is substantially deeper than the tray which it receives and is dimensioned so that when the tray is oriented in one direction it may rest on the bottom of the basin, with the soak solution in the basin covering all of the instruments carried by the tray, and when oriented in a second position at right angles to the first it may be suspended by the basin with the tray's apertured bottom wall above the liquid level. Support shoulders are provided for suspending the tray in its second position, and stop means limit the extent of relative lateral movement of the tray in either of its positions. The basin includes means for restraining wave development and for reducing the possibilities of splashing and spilling should the basin be moved with liquid therein.
