Abstract: A collapsible patient supporting carrier configured as either a backboard or a stretcher for being pulled or towed behind a person, animal or vehicle, such as a bicycle, motorcycle, snow mobile or jet ski. The carrier comprises a plurality of support sections interconnected by connecting mechanisms that are configured to selectively place the carrier in a collapsed condition having a support surface for carrying medical supplies or an extended condition for transporting an injured person. Each support section is made up of a frame and one or more support members, such as a rigid plate or a somewhat flexible material, attached to the frame. The forward end of the carrier has a tow connector member to connect to a tow member for towing. Transport members, such as wheels, skis or a floatation member, are operatively connected near the second end of the carrier to facilitate movement over a surface.
