| 摘要 |
To facilitate rapid, accurate, blind access to the larynx or esophagus such as for emergency intubation of a patient's trachea and suctioning of the hypopharynx or esophagus, a medical device ( 10 ) includes an anatomically contoured guide element ( 12 ) having a channel ( 22 ) therethrough. Guide element ( 12 ) is positioned about and atop the larynx such that the wall of the channel forms an upward continuation of the laryngeal wall. An orotracheal tube ( 18 ) advanced through the channel is guided exclusively into the larynx and trachea without substantial risk of accidental intubation of the esophagus or other areas of the hypopharynx. Tunnels ( 150, 160 ) may be provided through the guide element for blindly guiding or aiming other tubular-type members selectively into the esophagus or larynx. A tubular handle ( 14 ) or curved blade ( 454 ) is connected to the guide element ( 12 ) to blindly insert guide element ( 12 ) into the throat. Alternative embodiments ( 310, 350, 410, 450 ) of medical device ( 10 ) are also described. |
