ABSTRACT:
This invention relates to a new and improved intubating device and more particularly to an intubating device wherein it can be determined that the metal stylet is properly positioned by the aspiration process without removal and subsequent reinsertion of the metal stylet. The intubating device consists of an assembly of a feeding tube in assembled relationship with a tube connector. A stylet holder having a stylet attached thereto is adapted to be assembled in telescoping relationship with the flexible feeding tube. The metal stylet is made of twisted metal wire so as to provide a rough exterior. The metal stylet is embedded in a blind hole in the hub of the stylet holder and is offset from the liquid passageway.
