PCT No. PCT/SE83/00432 Sec. 371 Date Jul. 13, 1984 Sec. 102(e) Date Jul. 13, 1984 PCT Filed Dec. 7, 1983 PCT Pub. No. WO84/02268 PCT Pub. Date Jun. 21, 1984.A device for stabilizing the pelvis of a lying patient in a preselected angular position relative to a conventional flat bed includes a generally, disc shaped body with two basically parallel planar surfaces. The body is intended to be placed between the lower extremities of the patient and is designed with a cavity, which extends from the edge of the body toward its center and conforms to and is somewhat bigger than the contours of the patient's pelvis as seen from the side, and has parts protruding from the respective planar surfaces, and preferably arranged in pairs on opposite sides of the body. The protruding parts are arranged to support the body far enough above the bed to give room for one extremity between the bed and the planar surface facing the bed while the other extremity rests on the opposite planar surface, thereby providing some moving space for the extremities between the protruding parts. In the said cavity supporting surfaces are arranged to support the lumbar region of the patient on one side and on the other side the hip bones of the patient, whereby the pelvis is stabilized essentially at a right angle to the bed. |
