The invention includes a portable modularized medical unit that may be transported by airplane, helicopter, truck, rail, or ship to and from any location where emergency medical care, trauma care, surgical care, intensive care, isolation care, critical care, mass casualty, exam treatment or emergency medical evacuation are needed. The unit includes a rigid parallelepipedal frame that serves as the rigid exoskeleton of the unit that is a rigid aluminum parallelepipedal frame with a plurality of longitudinal metal tracks in the unit to provide the attachment or connection points for various medical components inside the internal portion of the portable modularized medical unit and that are rigidly attached to the interior surface of the base structure of the rigid parallelepipedal frame to provide multiple connection and attachment points for the components in an airworthy but removable manner to the base structure, walls, or roof of the rigid parallelepipedal frame so that the components internal to the unit may be attached, removed, relocated, replaced, and rearranged inside of the portable modularized medical unit.
