Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
238 words
An intubating device permitting aspiration of gastric juices to determine proper positioning of the device having a stylet which can be positioned within a human patient without removal of the stylet comprising: a. a tube connector having connected at one end thereof a flexible feeding tube for conveying liquid nourishment to the patient and having an opening at the other end; b. a stylet holder having a circular flange portion extending from the stylet holder for hand manipulation of the stylet holder and an opening at one end of the stylet holder for receipt of a supply of liquid nourishment; c. a hub at the other end of said stylet holder extending from said circular flange; d. a blind hole in said hub extending from the end of said hub towards said circular flange, said hole being offset from the center of said hub; e. a fluid passageway extending through said stylet holder; f. a metal stylet fixedly embedded in said blind hole and extending therefrom and forming a one-piece unit with said hub; g. said stylet holder and stylet adapted to be positioned in telescoping relationship with said tube connector and said feeding tube with the fluid passageway unobstructed by said stylet; h. whereby when the intubating device is initially positioned an aspiration process can be accomplished through the unobstructed fluid passageway and after the device is properly positioned liquid nourishment can flow unobstructed through said passageway.
