Abstract
Abstract A collapsible and portable stretcher having a breakdown rectangular frame and a flexible sheet forming a bed for the stretcher but removable therefrom. The flexible sheet has side flats which can be drawn and held together over the bed by way of hooks on one flap and cord-receiving members on the other flap, a cord being threaded through the cord-receiving members to form loops which are caught on the hooks, the cord then being drawn tight and snugged. The stretcher is rapidly disassembled and packed into a compact carrying pack formed from the bed itself and the removable flexible sheet can itself, without frame, be utilized for securing and carrying a patient.
