## Title
Packable emergency trauma stretcher

## Abstract

An emergency trauma stretcher comprised of flexible fabric such that the stretcher may be rolled or folded into a package for easy transport into locations where traditional stretchers are either not appropriate or not available. The stretcher is comprised of a support structure and handles. The support structure is comprised of longitudinal support members and lateral support members that are joined together at overlapping intersections. The handles are formed by looping the longitudinal and lateral support members at predetermined locations.

## Background
RELATED APPLICATION
This is the non-provisional filing of provisional application Ser. No. 60/328,382, filed on Oct. 11, 2001, entitled “Packable Emergency Trauma Stretcher.”


BACKGROUND OF THE INVENTION
This invention relates to a device comprising a light-weight flexible fabric stretcher for transporting injured humans or animals. Every year seriously injured humans and animals require transport from an emergency trauma situation where conventional stretchers or litters are not appropriate. Disaster sites, soft wet soil or sand, swat situations and circumstances where further dangerous episodes may prevent the entry of conventional medical services but nonetheless require a fast method to retrieve the critically injured person or animal. In situations such as these where conventional transport is not available or appropriate, rescue personnel may resort to carrying the injured to safety in a manner that may result in further injuring the person or animal.
There is a need for a flexible fabric stretcher that can be rolled or folded into a package that can be slung over a person's shoulder, carried by an animal, or dropped from a helicopter or other rescue transport without damage. The flexible stretcher must have no parts that can be destroyed during the impact from an air-drop of 100 feet of altitude. The stretcher must also be capable of being carried by an adult traversing distances that may be in excess of 200 feet.
SUMMARY OF THE INVENTION
The invention provides a stretcher comprising a support structure for transporting a body. The support structure is comprised of first set of longitudinal support members and a second set of lateral support members perpendicular to the first set of longitudinal support members. The stretcher further comprises a plurality of handles about the perimeter of the support structure. The support members of the stretcher are comprised of fabric. The support members of the stretcher may be bound by nylon thread or a heat seal, and the stretcher is foldable about itself to form a compact package.



BRIEF DESCRIPTION OF THE DRAWINGS
The invention is described in greater detail in the following description of examples embodying the best mode of the invention, taken in conjunction with the drawing figures, in which:
FIG. 1 is a top plan view of a first embodiment of the stretcher showing a lattice-like pattern of the support members and loop formation of the support members wherein the ends of the loops are used as handles, and
FIG. 2 is a top plan view of a first embodiment of a handle of the stretcher showing the support members gathered at the end of the loop to form a handle, which is shown as being stitched together.



DESCRIPTION OF EXAMPLES EMBODYING THE BEST MODE OF THE INVENTION
For the purpose of promoting an understanding of the principles of the invention, reference will be made to the embodiments illustrated in the drawings. It will, nevertheless, be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the invention illustrated herein, being contemplated as would occur to the one skilled in the art to which the invention relates.
The stretcher 10, as shown in FIG. 1, is comprised of a lattice-like support structure also forming handles. The support structure is comprised of a first set of longitudinal support members 12 and a second set of lateral support members 14 that are perpendicular to the first set of longitudinal support members 12. The first set of longitudinal support members 12 and the second set of lateral support members 14 are comprised of natural or man-made synthetic fiber, rope or yarn form, or nylon strapping construction. The stretcher 10 can hold an adult human or animal, and can be carried by at least two persons. The first set of longitudinal support members 12 and the second set of lateral support members 14 are looped at a plurality of points about the perimeter of the stretcher 10 to form handles 16. Alternatively, a solid piece of fabric may be used to form the entire span of the stretcher 10 so long as the solid piece of fabric maintains the foldable and packagable properties of the stretcher 10.
The stretcher 10 is preferably held together by stitching the first set of longitudinal support members 12 and the second set of lateral support members 14 at overlapping intersections 18 with a nylon thread or the like. Alternatively, the intersections 18 may be stitched together with any material that will be strong enough to hold the stretcher 10 together when the weight of a human or animal is applied to the stretcher 10. Additionally, the intersections 18 may also be riveted, heat sealed or bonded by an adhesive so long as the bonding means is strong enough to hold the first set of longitudinal support members 12 and the second set of lateral support members 14 of the support structure 11 together when the weight of a human or animal is applied to the stretcher 10.
FIG. 2 illustrates a close-up view of the handle 16 of the stretcher 10. The handles 16 are formed at the end of predetermined support members 12, 14 by gathering the support members 12, 14 in a manner to provide enhanced gripping capability. The handle 16 is preferably created by folding the first linear support member 12 or the second linear support member 14 in half and stitching the folded support member 12, 14 together with thread near the edges of the support member 12, 14. Alternatively, the handle 16 may be formed by way of heat seal or bonded by an adhesive so long as the bonding means is strong enough to hold the handle 16 together when the weight of a human or animal is applied to the stretcher 10. Additionally, the handles 16 may be formed by wrapping the first linear support member 12 or the second linear support member 14 around a flexible band made out of a material such as plastic or rubber. Alternatively, straps or shoulder harnesses may be hooked into the handles 16 thereby allowing fewer rescuers to carry a greater weight. Furthermore, the handles 16 may be larger than shown in the illustration so that they may be utilized in a variety of ways, such as being slung over the shoulder of one or more people.
Various features of the invention have been particularly shown and described in connection with the illustrated embodiments of the invention. However, it must be understood that these particular products, and their method of manufacture, do not limit but merely illustrate, and that the invention is to be given its fullest interpretation within the terms of the appended claims.

## Claims

1. A stretcher comprising:
a support structure for transporting a body; 
the support structure comprising a first set of longitudinal flexible support members and a second act of lateral flexible support members perpendicular to and intersecting the first set of support members;
