US 5,121,514 A · Emergency support device with flexible polyethylene sheet

Abstract

This invention is an advancement in the safe and practical methods of transporting sick or injured patients. The Manhandler is a flexible stretcher constructed of pliable materials. The injured patient is firmly secured to the cot portion of the system by a flexible wrap of sturdy material that extends along each side of the patient's entire body and is secured across his body by a series of strong straps. The litter and the wrap are attached to two parallel flexible strips of material which form lifting grips. These side grips provide support when lifted from the side. A solid sheet of plastic material provides rigidity to the cot portion of the stretcher when side lift is applied, yet remains flexible to allow elevation of the feet and head when such lift is released. The supporting material is radio-opaque to allow x-rays without the necessity of removing the patient from the litter. The longitudinal movement of the patient is restrained, both by the securing straps and an additional stabilizing wrap at the foot of the stretcher. A bi-fold option of the stretcher is available which allows the cot portion of the system to be folded in half for use with children and smaller patients.

Dependent claims

An emergency support device for lifting and transporting a human patient while at the same time supporting and substantially immobilizing the patient, comprising:

an axially elongate unitary support layer made of a flexible sheet of polyethylene for extending along and providing support from beneath the patient, said support layer having a longitudinal axis and a transverse axis wherein said longitudinal axis extends the relatively longer length of the support layer and said transverse axis extends across the relatively shorter width of the support layer;
a top layer and a bottom layer surrounding the support layer and a first and second side wrap, each trap being integral with at least one of the top layer or bottom layer, each wrap extending along the sides of and at least partially across the top of the patient;
and
a plurality of straps for securely wrapping the side wraps around the patient;
wherein application of an upward lifting force along the longitudinal edges of the support layer substantially increases the axial rigidity of the support layer so as to provide support along the axial length thereof.

An emergency support device for lifting and transporting a human patient while at the same time supporting and substantially immobilizing the patient, comprising:

an elongated, generally rectangular support layer made from a unitary flexible sheet of polyethylene and dimensioned for supporting a human patient in a supine position, said support layer having a longitudinal axis extending from a first end of the support layer to a second end of the support layer along the relatively longer dimensioned thereof, and a transverse axis extending generally perpendicularly to the longitudinal access, from a first side of the support layer to a second side of the support layer;
such that in relation to said patient the longitudinal axis extends generally from head to toe, and the transverse axis extends generally from shoulder to shoulder of said patient;
said support layer being movable from a first position in which said support layer lies substantially within a plane, and a second position in which said first and second sides of said support layer are elevated above said plane such that said support layer in said second position generally defines a portion of the surface of a cylinder;
a top layer and a bottom layer surrounding the support layer and a first and second side wrap, each wrap being integral with at least one of the top layer or bottom layer, each wrap extending along the sides of and at least partially across the top of the patient, and a plurality of straps for securely wrapping the side wraps around the patient;
wherein application of an upward lifting force along the first and second sides of said support layer, when a patient is lying on said support layer, moves said support layer from said first position to said second position thereby causing said support layer to assume a configuration having an arcuate curvature from side to side while retaining substantial linearity from said first end to said second end along the longitudinal axis of the support layer.
