Abstract: A patient arm support comprises a first elongate resilient segment extending along an axis having a top and a bottom surface. The bottom surface is configured to rest upon a substantially planar surface and the top surface is configured to support an upper portion of the patient's arm. A second elongate resilient segment is attached to the first elongate resilient segment extending along the axis. The second elongate resilient segment has a top and a bottom surface, the bottom surface being configured to rest upon a substantially planar surface and the top surface being configured to support a lower portion of the patient's arm. A lengthwise channel is formed in the top surface of the second elongate resilient segment. The lengthwise channel may have a V-shaped cross-section configured to receive a portion of the patient's hand.

Abstract: A tubular assembly having a plurality of lumens is configured for insertion into the mouth and throat of a patient with a proximal end of the tubular assembly extending from the patient's mouth and a distal end of the tubular assembly extending into the patient's esophagus. The tubular assembly further includes a transition portion near the tubular assembly. The transition portion is configured to transition from a relatively radially large proximal end to a relatively radially small distal end, with the relatively radially small distal end being in communication with at least one of the lumens. The relatively radially large proximal end is configured to abut the aryepiglottic folds of the patient to arrest insertion of the tubular assembly with the relatively radially small distal end of the transition portion extending into the patient's esophagus.
