Abstract
Abstract A break-away scoop stretcher composed of three detachable frame sections adapted to be selectively interengaged to extricate and transport a critically injured person in various positions, including prone, seated and fetal, depending upon the position in which the injured person is found, the stretcher including pivot lock means for interconnecting the several sections in the desired position of use as well as permitting each section to be separated into opposing halves which may be fitted together about the injured person to avoid twisting, turning or other possible injurious movement to the person during extrication from the site of the injury and subsequent transport to a hospital.
