Abstract: A management system for flexible lines, such as tubes and cables, used in the medical treatment of a patient includes a flexible expanse of material and a plurality of separate connectors mounted at different positions on the material. The connectors are separately operable for attaching and detaching respective lines independently of the attachment and detachment of other lines. Each of the connectors is preferably detachably mountable upon the material alternatively in different positions and orientations to accommodate the random positioning and orientation of the lines. The expanse of material lies supportably atop the body of the patient and can be selectively detachably separated into two line-connecting parts to quickly enable access to the patient's chest and abdominal areas for treatment. The expanse of material adjustably fastens selectively to patient reclining supports of different types such as stretchers and beds to facilitate transfer of the patient.
