| 摘要 |
An extendable intubation device is disclosed that includes a tube assembly having a plurality of elongated tubes. Within the assembly, a base tube is coupled with an extension tube to maintain a continuous fluid pathway along the tube assembly during a fore-and-aft movement of the extension tube relative to the base tube. For example, a portion of the extension tube can be co-axially mounted within the lumen of the base tube. Additional extension tubes can be included. The length and curvature of the extendable intubation device can be manually adjusted by a control unit having at least one control wire. The control wire(s) are attached to the distal end of the most distal extension tube and can be employed to reciprocally move one or more of the extension tubes in a fore-and-aft movement relative to the base tube and/or selectively bend the tube assembly. |
