Arm immobilization device and associated methods
The present disclosure provides exemplary arm immobilization devices for a person and associated methods of use. Thus, in one aspect, the disclosure provides a device including or comprising an outer shell including an internal cavity and a configurable structure disposed within the internal cavity of the outer shell. The outer shell can be configured and dimensioned to accommodate an arm of a person thereon. Expansion or contraction of the configurable structure can drive expansion or contraction of the outer shell. In another aspect, the disclosure provides methods for immobilizing an arm of a person that include providing an arm immobilization device and supporting the arm of the person with the outer shell and the configurable structure.
1. An arm immobilization device, comprising:
an outer shell including an internal cavity, wherein the outer shell defines an accordion structure, wherein the accordion structure includes bellow-type pleats,
a configurable structure disposed within the internal cavity of the outer shell, wherein the outer shell is configured and dimensioned to accommodate an arm of a person thereon, and
wherein expansion or contraction of the configurable structure drives expansion or contraction of the outer shell one or more adjustable straps for regulating a direction of expansion or contraction of the configurable structure and wherein expansion or contraction of the configurable structure is adjustable for varying degrees of at least one of abduction, adduction, internal rotation and external rotation.
2. The arm immobilization device of claim 1 , wherein the outer shell and the configurable structure provide support to the arm of the person.
3. The arm immobilization device of claim 1 , wherein the outer shell is configured and dimensioned to accommodate a detachable brace thereon.
4. The arm immobilization device of claim 1 , wherein the outer shell comprises planar side surfaces.
5. The arm immobilization device of claim 1 , wherein the configurable structure is at least one of an air-filled bladder, a liquid-filled bladder, one or more springs, a spring mechanism, a squeezable foam, and a memory foam.
6. The arm immobilization device of claim 1 , wherein the one or more adjustable straps include a buckle or a ratchet mechanism.
7. A method for immobilizing an arm of a person, comprising:
providing an arm immobilization device, the arm immobilization device including:
an outer shell including an internal cavity, wherein the outer shell defines an accordion structure, wherein the accordion structure includes bellow-type pleats,
a configurable structure disposed within the internal cavity of the outer shell, and
supporting the arm of the person with the outer shell and the configurable structure adjusting expansion or contraction of the configurable structure to vary a degree of at least one of adduction, internal rotation and external rotation; regulating a direction of expansion or contraction of the configurable structure by adjusting a length of adjustable straps secured to the outer shell.
8. The method of claim 7 , comprising detachably securing the outer shell to a belt secured around a torso of the person.
9. The method of claim 8 , comprising adjusting a position of the outer shell relative to the belt along a circumference of the belt and a vertical direction along the belt.
10. The method of claim 7 , comprising securing the arm of the person to the outer shell.
11. The method of claim 7 , comprising expanding or contracting the configurable structure to drive expansion or contraction of the outer shell.
12. The method of claim 7 , wherein the adjustable straps control expansion or contraction of the outer shell.
