Abstract: A medical bolster for alleviating the effects of poor circulation supports either the legs above the heart or the heart above the extremities to improve blood and lymph fluid flow in a patient. The collapsible bolster has an articulated frame pivotally connected together for adjusting the angle between the base frame member and the support frame member. A brace extends between the base frame and the support frame to fix and secure the frame in a selected position. The brace has a safety stop to prevent injury during collapse and the brace is oriented to vector the forces within the articulated frame.

Abstract: A folding bolster is used to treat circulation problems to prevent pooling of fluids in patients. The bolster has three members connected together end-to-end. A first member has a free end and a hinged end connected to a center member which has a hinged end and flexible joints connecting the base member which includes a ratchet device. The members are folded together to form an adjustable triangular frame with the free end of the first member engaging the ratchet device. A patient is supported by the center member to improve circulation.
