Abstract

Abstract A portable treatment table comprises a plurality of separate patient support table sections interconnectable for supporting a patient during treatment at a convenient working level above the floor while lying in a generally horizontal position. Each of the table sections includes a cushion assembly with drops for supporting a portion of the patient's body mounted on a frame and a plurality of support legs are pivotally interconnected with the frame for movement between a folded-up position inside the frame for transporting the table sections and a downwardly extended position for supporting the patient during treatment. Connectors are provided for detachably interconnecting the frames of the table sections and a detachable head piece assembly is provided for supporting a patient's head for cervical adjustment while lying on the interconnected table sections. When not in use, the head piece assembly is stowed for transport beneath the cushions of the table sections inside the folded-up legs and frame.
