  • Patent number: 6508757
    Abstract: A cost-effective fiberoptic endotracheal intubation aid that comprises a petalled tubular stylet, a medial member and a compress device is disclosed. The petalled tubular stylet is a section of tube made of malleable material and has a proximal end splitted into multiple longitudinal petals of certain length. The medial member is a resilient thin flat sheet with edge curb and the compress device is a clamp-like device.Such an intubation aid can be easily used in combination with conventional flexible fiberoptic bronchoscope and conventional endotracheal tube (E.T.). It will make the flexible insertion probe of F.O. bronchoscope as firm, preformable and manipulatable as a regular solid-wire stylet. Intubators using the present invention are able to visualize patient's pharynx area and simultaneously manipulate the tubular stylet for guiding E.T. into patient's trachea to a desired location.
