Removable Elbow Brace

Abstract

A brace to protect an elbow during healing, particularly for pediatric applications, is constructed from multiple thermoformable parts. The thermoformable parts harden like a cast, fitting partially around the humerus and the forearm as well as covering the posterior aspect of the elbow. The thermoformable parts are held in place by straps that extend between the parts, cupping the humerus and forearm therebetween. The brace may be customizable to any shape and size to the wearer. The brace may be easily removed for comfort or for washing and then replaced to provide continued support.

DETAILED DESCRIPTION

[0012] Before the present invention is described in further detail, it should be understood that the invention is not limited to the particular embodiments described, and that the terms used in describing the particular embodiments are for the purpose of describing those particular embodiments only, and are not intended to be limiting, since the scope of the present invention will be limited only by the claims.

[0013] An elbow brace according to an embodiment of the present invention is shown in FIGS. 1-3. Shell 10 is constructed of a single piece of thermoformable material, such as the Exos® thermoformable composite plastic material offered by DJO, LLC of Lewisville, Tex. A material of this type is taught by U.S. Pat. No. 5,645,671, which is incorporated by reference herein. The material is designed to be adjustable and reformable such that it may be conformed to any desired shape with the application of heat, and then provide a solid and rigid structure after cooling. A material such as Exos® is lightweight, waterproof, and relatively easy to clean. As shown in the figures, an upper shell section 12 of shell 10 is bent with respect to the lower shell section 14, with an elbow section 16 between these two sections of shell 10. The angle between upper shell section 12 and lower shell section 14 may be formed as desired by the medical professional applying the device, including as a right angle. As can be seen in the figures, shell 10 is shaped so that the patient's arm is cupped within the thermoformable material of shell 10, with openings at either end and around the sides of the elbow area such that air may easily pass to the patient's skin.

[0014] FIG. 4 depicts shell 10 in an alternative embodiment of the invention, in this case shell 10 shown as a flat piece before forming onto the arm of a patient. In this embodiment, shell 10 includes perforations through its thermoplastic material in order to improve the quantity of air reaching the patient's arm within the brace. Any number and size of perforations may be employed, provided that the rigidity of shell 10 is not compromised thereby. Shell 10 in this embodiment also includes slots 28 which are cut at elbow section 16. The purpose for slots 28 is to ease the formation process by providing relief at the portion of shell 10 that will be subject to the most substantial bending during the forming process. Any number of slots 28 may be including in this embodiment, and the depth of the slots may be modified as desired and as best suits any particular thermoplastic material used for the construction of shell 10.

[0015] The angle between upper shell section 12 and lower shell section 14 may be maintained during use while on a patient's arm by means of elbow strap 18. Elbow strap 18 passes from one side of upper shell section 12, under lower shell section 14, and then attaches at the opposite side of upper shell section 12. One or both ends of elbow strap 18 may be attached with hook-and-loop fasteners. One end of elbow strap 18 may be permanently attached with stitching, adhesives, or the like. Because hook-and-loop fasteners may be easily detached and reattached at various positions, elbow straps 18 may be adjusted for length as desired, which may to a limited degree adjust the angle between upper shell section 12 and lower shell section 14.

[0016] Upper shell section 12 and lower shell section 14 are formed by curling each of these ends of shell 10 into a roughly round shape around the area where the patient's arm is fitted. These sections 12 and 14 may be held closed around the arm during use by tightening connectors. In the embodiment of the figures, closures 20 that secure and tighten laces 22 extending from anchors 26 serve as the tightening connectors. Closures 20 contain a spool that allows for tightening or loosening of laces 22 by turning closures 20 either clockwise or counterclockwise. Closures 20 may be held to shell 10 by means of hook-and-loop fasteners. Anchors 26 may be attached to shell 10 by adhesives, stitches, or other secure means. Closures such as closures 20 are sold by, for example, BOA® Technology Inc. of Denver, Colo. Such a device is taught by U.S. Pat. No. 11,457,698, which is incorporated herein by reference. These closures are commonly used for sports equipment such as ski boot lacing. Other types of connectors could be used in alternative embodiments of the invention, including, for example, the use of straps or traditional lacing.

[0017] Ring pad 24 is attached within shell 10 inside elbow section 16, as seen most clearly in FIG. 1. Ring pad 24 is sized and positioned to receive the point of the patient's elbow when the device is worn. Ring pad 24 may be formed of any compressible yet sturdy material to provide comfort to the patient. Ring pad 24 may be formed of a water-resistant material in order to prevent damage to the device should it be exposed to rain or other sources of moisture. Ring pad 24 may be attached at elbow section 16 with any sufficiently durable adhesive.

[0018] To fit the device to the patient, shell 10 begins as a flat piece. Ring pad 24 is attached at elbow section 16 of shell 10. A medical professional bends and curls shell 10 to form upper shell section 12 fitted loosely around the patient's upper arm, while lower shell section 14 is fitted loosely around the patient's lower arm, with the patient's elbow resting comfortably in ring pad 24. Once shell 10 is shaped as desired, elbow strap 18 is pulled into place and secured with the hook-and-loop fasteners. Laces 22 are fitted around closures 20 at both upper shell section 12 and lower shell section 14, and then closures 20 are turned in order to draw these sections of shell 10 down securely but comfortably in place around the patient's arm. When the patient desires to remove the device, closures 20 are loosened so that laces 22 are released, and elbow strap 18 is removed at one or both ends.

[0019] Unless otherwise stated, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although any methods and materials similar or equivalent to those described herein can also be used in the practice or testing of the present invention, a limited number of the exemplary methods and materials are described herein. It will be apparent to those skilled in the art that many more modifications are possible without departing from the inventive concepts herein.
