Abstract
Abstract An arm sling includes a semi-rigid trough which partially encircles and supports a patient's forearm, wrist, and hand. A yoke is connected to the sides of the trough at a location away from the distal end. An adjustable-length strap extends upward from the yoke over the front of the patient's ipsilateral shoulder, diagonally across the patient's back, and transversly across the front of the patient's body to an attachment point on the trough near the patient's elbow. An elbow piece adjustably fixed to the trough accommodates various elbow angles and arm widths. The yoke supports the patient's forearm, wrist, and hand in a cantilevered fashion at various elevations, while not interfering appreciably with lateral movement of the distal end of the trough and rotation of the patient's upper arm at the shoulder joint.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
156 words
A method of supporting an arm of a patient, comprising the steps of: forming a semi-rigid arm support member into a trough having a pair of lateral side portions positioned on each side of the patient's forearm; partially encircling the patient's forearm with the trough; placing the elbow and distal end of the patient's arm within the trough; coupling one end of a strap to the middle portion of the trough and coupling the other end of the strap to the trough near the patient's elbow; extending the strap over the ipsilateral shoulder of the patient, diagonally downwardly across the patient's back, and across the front of the patient's body, and adjusting the length of the strap to suspend the trough from the strap and elevate the patient's forearm to a predetermined position while permitting lateral movement of the distal end of the patient's forearm and rotation of the patient's upper arm at the shoulder joint.
Claim 2
Independent Claim
156 words
A method of supporting an arm of a patient, comprising the steps of: forming a semi-rigid arm support member into a trough having a pair of lateral side portions positioned on each side of the patient's forearm; partially encircling the patient's forearm with the trough; placing the elbow and distal end of the patient's arm within the trough; coupling one end of a strap to the middle portion of the trough and coupling the other end of the strap to the trough near the patient's elbow; extending the strap over the ipsilateral shoulder of the patient, diagonally downwardly across the patient's back, and across the front of the patient's body, and adjusting the length of the strap to suspend the trough from the strap and elevate the patient's forearm to a predetermined position while permitting lateral movement of the distal end of the patient's forearm and rotation of the patient's upper arm at the shoulder joint.
Claim 3
Dependent Claim
48 words
The method of claim 1 including the steps of attaching the respective ends of a yoke member to one of a pair of lateral side portions of the semi-rigid support member, and suspending the trough with the patient's forearm therein in a cantilevered fashion from the patient's shoulder.
Claim 4
Dependent Claim
42 words
The method of claim 1 or claim 2 including adjustably fixing an elbow piece at a predetermined angle to the arm support member to accommodate the angle of the patient's elbow corresponding to elevation of the patient's forearm to the predetermined position.
Claim 5
Dependent Claim
49 words
The method of claim 1 or claim 2 including the step of adjustably fixing an elbow piece at the predetermined angle to the arm support member, and adjusting the width of the proximate end of the trough to accommodate the width of the patient's arm with pressure-sensitive engaging means.
