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.

Claims

1. In combination, a generally rectangular instrument tray having a bottom wall and having side and end walls upstanding from said bottom wall, at least one of said walls having apertures so positioned therein to provide for the substantially complete drainage of fluid from said tray;

said tray having a length, measured from one upstanding end wall to the other, substantially greater than its width, measured from one upstanding side wall to the other; and

a soak basin having bottom, side, and end walls defining a chamber for removably receiving said tray;

said chamber having a depth substantially greater than the height of the upstanding walls of said tray and being both longer and wider than said length of said tray;

whereby, said tray is selectively receivable in said chamber in a first position wherein the length of said tray extends longitudinally of said basin and in a second position wherein said length of said tray extends transversely of said basin;

support means provided by said basin for supporting said tray in a fluid drainage and instrument storage position with its bottom wall spaced a substantial distance above the basin'"'"'s bottom wall when said tray is in its second position;

stop means provided by said basin and engagable with said tray for preventing relative horizontal movement of said tray without restraining relative vertical upward movement of the tray when said tray is in its second position; and

flanges projecting outwardly from the top of said end walls of said tray;

said support means comprising shoulders provided by said side walls of said basin;

said shoulders being engagable with said flanges for supporting said tray in its elevated second position.

2. The combination of claim 1 in which said side walls of said tray are provided with outwardly projecting flanges merging with the flanges of said end walls of said tray.

3. The combination of claim 1 in which said shoulders project inwardly into said chamber from said side walls of said basin.

4. The combination of claim 3 in which said shoulders are spaced below the upper limits of the basin'"'"'s side walls.

5. The combination of claim 3 in which a pair of said shoulders are provided along each of said side walls of said basin;

said shoulders of said pair being located adjacent opposite ends of each side wall of said basin.

6. In combination, a generally rectangular instrument tray having a bottom wall and having side and end walls upstanding from said bottom wall, at least one of said walls having apertures so positioned therein to provide for the substantially complete drainage of fluid from said tray;

said tray having a length, measured from one upstanding end wall to the other, substantially greater than its width, measured from one upstanding side wall to the other; and

a soak basin having bottom, side, and end walls defining a chamber for removably receiving said tray;

said chamber having a depth substantially greater than the height of the upstanding walls of said tray and being both longer and wider than said length of said tray;

whereby, said tray is selectively receivable in said chamber in a first position wherein the length of said tray extends longitudinally of said basin and in a second position wherein said length of said tray extends transversely of said basin;

support means provided by said basin for supporting said tray in a fluid drainage and instrument storage position with its bottom wall spaced a substantial distance above the basin'"'"'s bottom wall when said tray is in its second position; and

stop means provided by said basin and engageable with said tray for preventing relative horizontal movement of said tray without restraining relative vertical upward movement of the tray when said tray is in its second position;

said stop means comprising pairs of spaced upstanding opposing surfaces provided along each side wall of said basin;

said opposing surfaces being spaced apart a distance slightly greater than the width of said tray at each end thereof for limiting horizontal movement of said tray upon engagement with the side walls of said tray.

7. The combination of claim 6 in which said support means is engageable with said tray to support the tray with its bottom wall spaced above the basin'"'"'s bottom wall at a distance greater than the height of the tray'"'"'s upstanding walls.

8. The combination of claim 6 in which said pairs of spaced upstanding opposing surfaces project inwardly from each side wall of said basin.

9. The combination of claim 8 in which said basin is also provided with second stop means for limiting the extent of lateral sliding movement of said tray when the same is in its first position, said second stop means including pairs of spaced upstanding opposing second surfaces projecting inwardly from each end wall of said basin;

said pairs of second surfaces being spaced apart a distance slightly greater than the width of said tray at each end thereof for limiting the extent of lateral movement of said tray when the same is in its first position.

10. The combination of claim 9 in which said second surfaces merge with said first-mentioned surfaces to define reentrant corner portions of said basin;

said reentrant corner portions producing wave interference for reducing possibilities of splashing and spilling when said basin is moved with liquid contained therein.
