Abstract

An adjustable type of wheeled sick bed can also act as a wheel chair, having a spring mattress in three sections pivoting with each other. The mattress is structured in a weblike network, and under its front and rear sections are provided rocker gears for rotating the sections from a horizontal position to yield the wheel-chair. A sump is provided beneath the central section of the mattress to exhaust via a drainage pipe or urinal. A plastic covering is hung vertically to cover the front and rear sections of the bed, to shield the patient while taking a bath on the bed, the sullied water of the bath exiting via the sump and drainage pipe. The central part of the bed, at a point corresponding to the buttocks of a patient lying in the bed, is provided with a soft, hollow-set round urn, to allow the patient sitting on the bed to eliminate. The sick bed is easy to assemble and disassemble, and is portable, light-weight and highly versatile.
