Abstract
Abstract A readily cleaned and sterilized drainage platform for collecting fluids discarded during surgical operations includes a collection basin having three support trays. The two other or wing support trays are attached by overlapping hinges to a central support tray for convenient folding of the platform. When folded, the platform can be easily stored or, by extending a set of retractable rollers on the underside of the central support tray, can be readily moved within or between operating rooms. The drainage platform provides a confortable non-slip surface upon which several medical personnel may stand during an operation, and, for the convenience of the surgeon, also provides adjustable instrument trays.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
268 words
A portable surgical drainage platform for collecting fluids discarded during surgical operations, said platform comprising: a central support tray and two outer support trays situated adjacent opposite edges of said central support tray, each of said support trays including a trough at one end, an upper fluid receiving surface having a slight inclination for channeling fluids toward and into said trough, a drain for evacuating fluids from said trough, and means situated below said upper fluid receiving surface for supporting the same; means for rotatably attaching said outer support trays to said central support tray, said attaching means including overlapping hinges to prevent fluid from leaking between said outer support trays and said central support tray; means for locking each said outer support tray in a folded position when rotated about said attaching means with respect to said central support tray; means for damping the downward movement of each said outer support tray when unfolded to align said outer support trays with said central support tray; a plurality of removable perforated mats, said mats being situated upon said upper fluid receiving surfaces of said support trays to provide a non-slip surface through which fluids may pass; and means for moving said platform, said moving means including a plurality of vertically extendable and retractable roller mechanisms situated below said upper fluid receiving surface of said central support tray, a hand lever which can be releasably locked in one of two primary positions, and means for extending or retracting all said roller mechanisms simultaneously in response to the positioning of said hand lever to, respectively, raise or lower said platform.
Claim 2
Dependent Claim
