    • Airway devices are provided for introducing an endoscope into a patient's gastrointestinal system that include a tubular proximal portion sized for placement in an oral cavity and including a passage for receiving an endoscope therethrough, and a curved distal portion. The distal portion may have a “C” shaped wall defining a channel extending from the passage to a distal tip of the distal portion. The proximal portion may include a flange for placement adjacent the patient's teeth when the airway device is inserted into the oral cavity, and the airway device may include sampling and fluid delivery lumens including ports on the face of the flange. The sampling lumen may include an inlet port within the passage, and the fluid delivery lumen may include an outlet port communicating with the channel such that the outlet port is offset distally relative to the inlet port.
    • 提供气道装置用于将内窥镜引入到患者的胃肠系统中,该系统包括尺寸适于放置在口腔中的管状近端部分,并且包括用于接收内窥镜的通道和弯曲远端部分。 远侧部分可以具有限定从该通道延伸到远侧部分的远侧末端的通道的“C”形壁。 当气道装置插入口腔时,近侧部分可包括用于放置在患者牙齿附近的凸缘,并且气道装置可包括取样和流体输送腔,其包括在凸缘表面上的端口。 采样腔可以包括通道内的入口端口,并且流体输送腔可以包括与通道连通的出口端口,使得出口端口相对于入口端口向远侧偏移。
