  • Patent number: 8087112
    Abstract: A lightweight, collapsible and portable stretcher for effective use under extreme circumstances such as use in disaster and war affected terrains. The stretcher includes a wheel assembly having an alternative use as a container for the collapsible stretcher. The invention has particular advantages in military or disaster environments in that it allows one person, a carrier, to perform an evacuation of an injured person, whereas prior art stretchers require two or more persons to effectuate an evacuation of an injured person. Additionally, the carrier person can utilize the stretcher to transport or pull an injured person while reserving independent functions of his or her hands. Accordingly, the lightweight collapsible and portable stretcher can be operated hands-free by a single carrier person.
