  • Combined pelvic tray, workstation and fluid collection device
    Patent number: 5454797
    Abstract: A disposable laminar device for collecting body fluids during obstetric, gynecologic, proctologic or urologic procedures or examinations is formed from sheet plastic. The device includes a planar area which is placed on the edge of an examination table, with the patient's buttocks on top. The patient's weight holds the device, but it may also be clipped to the table. Projecting outward from and cantilevering off the table edge is a collection region of the lamina, contiguous with the planar area. The collection region includes a drain portion which receives and directs fluids draining from the perineal area of the patient into a cup integrally formed in the lamina. The drain portion is bordered by a raised ridge or dike which prevents fluids from spreading under the buttocks onto the planar area. The collection region also preferably includes a flat work area and receptacles formed therein to hold solutions, instruments, swabs, and the like.
