A system for transporting an ill or injured patient includes a stretcher in combination with a plurality of medical care modules that respectively include medical devices such as an infusion pump, an oxygen supply device, a defibrillator, an EKG unit, or the like, and medical and first aid supplies such as bandages, splints, IV supplies, drugs, medical instruments, and the like. The stretcher includes a frame and a patient support surface, as well as module bays provided under the frame or a module carrier removably mounted on the frame. The several medical care modules each have the same dimensions and configuration so that they are modularly interchangeable to be received in any one of the module bays or on the module carrier. When the medical care modules are slidingly pushed into the module bays, electrical contacts are engaged to connect the modules with an electrical power supply and a data transfer bus, through the stretcher.
