Medical instrument container system
View Patent ↗The system contains a molded plastic reticulated tray composed of a continuous rib that forms a tray rim and a plurality of intersecting ribs defining relatively large openings therebetween. The intersecting ribs are dished and having opposite ends connected to the continuous rib at spaced apart locations therealong. The plurality of intersecting ribs have rounded surfaces so that a fluid sterilant directed at the plurality of intersecting ribs from the outside, upon flowing through said openings, will follow and intimately contact said rounded surfaces to the tray interior so that those surfaces are cleaned thoroughly.
1. A container system for medical instruments, the system comprising:
a molded plastic reticulated tray having a continuous rib that forms a tray rim about a perimeter of the molded plastic tray;
a tray wall, formed from a plurality of ribs connected to the tray rim, the plurality of ribs having opposite ends connected to the tray rim at spaced apart locations therealong;
a middle portion of the plurality of intersecting ribs forming a tray base, the tray base having a plurality of perpendicularly intersecting ribs formed from the plurality of ribs, the intersecting ribs having a circular cross-section and central axes configured in a plane, said intersecting ribs being dished and defining openings therebetween whereby a fluid sterilant directed at the plurality of perpendicularly intersecting ribs from the outside, upon flowing through said openings, will follow and contact rounded surfaces to the tray so that those surfaces are cleaned; and
at least one instrument holder having a pair of resilient legs wherein each of said legs includes a free end terminated by a pair of quasi-hemispherical clips facing opposing directions and releasably engaging said plurality of intersecting ribs.
2. The container system defined in claim 1 , wherein the total area of said openings is at least twice the total longitudinal-sectional area of said plurality of intersecting ribs.
3. The container system defined in claim 1 , wherein the tray is molded of polyphenylsulphone.
4. The container system defined in claim 1 , wherein the tray is generally rectangular and said openings are square.
5. The container system defined in claim 4 , wherein the tray includes at least two similar latch fixtures affixed to the continuous rib opposite and facing away from one another, each latch fixture including a journal bearing and a keeper surface.
6. The container system defined in claim 5 , and further including a latch member hinged to each latch fixture at the journal bearing thereof.
7. The container system defined in claim 1 , and further including a reticulated cover which is a mate to said tray so that when the cover is inverted and positioned with its continuous rim in register with the continuous rim of the tray, the tray and cover make line contact and form a cage.
8. The container system defined in claim 7 and further including means for releasably clamping together the continuous rims of the tray and cover.
9. The container system defined in claim 8 , wherein the clamping means comprise a plurality of similar first latch fixtures affixed to the continuous rib of the tray, said first latch fixtures being opposite and facing away from one another, a plurality of second latch fixtures affixed to the continuous rib of the cover, said second latch fixtures being opposite and facing away from one another, each of said latch fixtures including a journal bearing and a keeper surface, said first and second latch fixtures being located directly opposite one another when the continuous ribs of the tray and cover are in register with one another, said opposite latch fixtures constituting a cooperating pair of latch fixtures, and a latch member hinged to one of each cooperating pair of latch fixtures at the journal bearing thereof, each said latch member being adapted to engage the keeper surface of the other latch fixture of each cooperating pair of latch fixtures.
10. The container system defined in claim 1 wherein said plurality of intersecting ribs include a first set of ribs spaced parallel to one another, a second set of ribs spaced parallel to one another, said first and second sets of ribs being orthogonal so that the ribs define rectangular openings.
11. The container system defined in claim 10 wherein said instrument holder is spanning at least one of said openings.
12. The container system defined in claim 11 wherein the length of each clip is slightly less than the side length of each of said openings.
13. The container system defined in claim 11 wherein said instrument holder also includes a plurality of spaced-apart depending posts which are adapted to straddle one of said plurality of intersecting ribs when the instrument holder is releasably engaging said different ones of said plurality of intersecting ribs.
14. The container system defined in claim 1 , wherein said pair of quasi-hemispherical clips are aligned along an axis substantially at the center of both of said quasi-hemispherical clips, wherein the axis is positioned substantially perpendicular to an axis aligned with one of each of said legs and substantially perpendicular to a first plane and a second plane, wherein one clip of said pair of quasi-hemispherical clips is located within the first plane and the other clip of said pair of quasi-hemispherical clips is located within the second plane, wherein said first plane is positioned in a different location along said axis than said second plane.
15. The container system defined in claim 1 , wherein each of said legs are positioned to be twisted about an axis aligned along a length of one of each of said legs, whereby twisting at least one of said legs displaces said pair of quasi-hemispherical clips from at least one of said plurality of intersecting ribs.
