    • Many embodiments of an airway assembly and methods of using an airway assembly are disclosed. In one embodiment, an airway assembly includes an outer tube, an inner tube disposed coaxially with the outer tube, and a seal disposed on the inner tube. The seal is movable between a collapsed position and an expanded position where the seal engages an airway. Another embodiment is an airway assembly that includes an outer tube having a proximal portion and a distal portion, and an inner tube disposed coaxially with the outer tube. The inner tube has a proximal portion and a distal portion. The proximal portion of the outer tube has an outer diameter that is larger than an outer diameter of the distal portion of the outer tube. The proximal portion of the inner tube has an outer diameter that is larger than an outer diameter of the distal portion of the inner tube. A further embodiment provides a method of using an airway assembly in an airway. The method comprises the steps of: providing an airway assembly having an outer tube, an inner tube disposed coaxially with the outer tube, and a seal disposed on the inner tube. The seal is inserted into the airway. The seal is moved from a collapsed position to an expanded position where the seal engages the airway. Fluid is moved through the inner tube and the seal. An additional embodiment provides a method of using an airway assembly in an airway. The method comprises the steps of: providing an airway assembly having an outer tube, and an inner tube disposed coaxially with the outer tube. The airway assembly is placed in a first status. The airway assembly is inserted into an airway when the airway assembly is in the first status. The outer tube is moved with respect to the inner tube to place the airway assembly in a second status. The outer tube is moved with respect to the inner tube to place the airway assembly in a third status.
    • 公开了气道组件的许多实施例以及使用气道组件的方法。 在一个实施例中,气道组件包括外管,与外管同轴设置的内管和设置在内管上的密封件。 密封件可在折叠位置和膨胀位置之间移动,其中密封件接合气道。 另一个实施例是一种气道组件,其包括具有近端部分和远端部分的外管以及与外管同轴设置的内管。 内管具有近端部分和远端部分。 外管的近端部具有比外管的远端部的外径大的外径。 内管的近端部具有比内管的远端部的外径大的外径。 另一实施例提供了一种在气道中使用气道组件的方法。 该方法包括以下步骤:提供具有外管,与外管同轴设置的内管和设置在内管上的密封件的气道组件。 密封件插入气道。 密封件从折叠位置移动到密封件接合气道的扩张位置。 流体通过内管和密封件移动。 另外的实施例提供了一种在气道中使用气道组件的方法。 该方法包括以下步骤:提供具有外管的气道组件和与外管同轴设置的内管。 气道组件处于第一状态。 当气道组件处于第一状态时,将气道组件插入气道中。 外管相对于内管移动以将气道组件置于第二状态。 外管相对于内管移动以将气道组件置于第三状态。
