CircOlectric (COL) bed, a brand name for an electronically controlled bed that can be vertically rotated 210 degrees, allowing a patient to move vertically from the prone to supine position. It is used especially in orthopedics and in the treatment of patients with severe burns and pressure ulcers. The bed consists of a strong aluminum circular frame supporting an anterior and a posterior straight frame within the exterior aluminum circle. The patient is “sandwiched” and secured between the two straight frames during rotation. Compare Foster bed, hyperextension bed, Stryker wedge frame.
