Abstract

Abstract A portable bathtub having a frame portion, a liner portion, and leg portions which facilitate use of the bathtub on a carrier surface such as on a stretcher. The frame includes a horizontally disposed, open center member made up of a plurality of telescoping portions. The dimensions of the open center of the frame are larger than the carrier surface. The legs are pivotally attached to the frame, and at least two of the legs are contoured so that upon selected rotation thereof the bottom support end can be located in different lateral positions whereby upon positioning the legs inwardly the tub can be supported on a stretcher and upon positioning the legs outwardly the frame can be lowered below the carrier surface with the liner thereof draped over the carrier surface and the frame and leg portions hanging down the sides, whereby to provide a flush surface on the carrier for easy movement of patients onto the carrier surface.
