Supraglottic tube for introducing laryngeal mask, has guiding unit mounted on guide lumen for modifying curvature radius of tube, where guiding unit includes pressure member and flexible traction member

摘要

The tube (1) has a respiration lumen (11) including breathing air supply and instrumentation. A guiding unit (4) is mounted on a guide lumen (13) for modifying a curvature radius of the tube. The guiding unit includes a pressure member and a flexible traction member (41), and an oesophageal lumen (12) is provided for an oesophageal input. The guide lumen is closed at a proximal end, and the guide lumen is arranged between the respiration lumen and oesophageal lumen. The lumens are formed by anterior-and posterior partition walls.
