Abstract
Abstract A guide device for an endotracheal tube which assists in intubating the trachea. The guide device includes a flexible bar which may be inserted in the endotracheal tube. A flexible line extends along the bar and has a free length at the inner end of the bar. When the line is pulled, the free length shortens and causes the inner end portion of the bar to flex in bowed fashion against the endotracheal tube. This urges the tube forwardly toward the trachea and away from the esophagus.

Claim 1
Independent Claim
358 words
In a device for intubating the trachea, the combination of: an elongate endotracheal tube of flexible construction adapted to intubate the trachea, said tube having one end portion insertable into the trachea and an opposite end portion which remains outside of the body during intubation; an elongate flexible bar member disposed within said tube and having a length to extend substantially between said end portions of the tube, said bar member having a first end located adjacent said one end portion of the tube and a second end located adjacent said opposite end portion of the tube; a fitting removably attached to said second end portion of the tube and adapted for connection with an air source to direct air into the endotracheal tube, said fitting having a side portion; an elongate flexible line extending generally along the length of said bar member and having one end connected with said first end of the bar member and an opposite end extending slidably through said side portion of the fitting and adapted to be pulled from the exterior of the endotracheal tube with the second end of said bar member contacting the fitting to retain the bar member in said tube when said line is pulled, said line having a slidable connection with said bar member at a preselected location thereon spaced from said first end of the bar member to provide a free length of the line between said first end of the bar member and said preselected location; and means for establishing a sliding connection of said line with said bar member at a location between said first end of the bar and said preselected location, whereby pulling of said opposite end of the line shortens said free length of the line to effect bowing of said bar member between said first end and said preselected location to engage the bar member against said tube in a manner to curve said one end portion of the tube toward the trachea, said sliding connection holding the line adjacent said bar member to effect smooth bowing of the bar member between said first end portion and said preselected location.
Claim 2
Dependent Claim
358 words
In a device for intubating the trachea, the combination of: an elongate endotracheal tube of flexible construction adapted to intubate the trachea, said tube having one end portion insertable into the trachea and an opposite end portion which remains outside of the body during intubation; an elongate flexible bar member disposed within said tube and having a length to extend substantially between said end portions of the tube, said bar member having a first end located adjacent said one end portion of the tube and a second end located adjacent said opposite end portion of the tube; a fitting removably attached to said second end portion of the tube and adapted for connection with an air source to direct air into the endotracheal tube, said fitting having a side portion; an elongate flexible line extending generally along the length of said bar member and having one end connected with said first end of the bar member and an opposite end extending slidably through said side portion of the fitting and adapted to be pulled from the exterior of the endotracheal tube with the second end of said bar member contacting the fitting to retain the bar member in said tube when said line is pulled, said line having a slidable connection with said bar member at a preselected location thereon spaced from said first end of the bar member to provide a free length of the line between said first end of the bar member and said preselected location; and means for establishing a sliding connection of said line with said bar member at a location between said first end of the bar and said preselected location, whereby pulling of said opposite end of the line shortens said free length of the line to effect bowing of said bar member between said first end and said preselected location to engage the bar member against said tube in a manner to curve said one end portion of the tube toward the trachea, said sliding connection holding the line adjacent said bar member to effect smooth bowing of the bar member between said first end portion and said preselected location.
Claim 3
Dependent Claim
38 words
The combination set forth in claim 1, wherein said establishing means comprises a loop attached to said bar member between said first end and said preselected location, said free length of the line extending slidably through said loop.
Claim 4
Dependent Claim
51 words
The combination set forth in claim 1, wherein: said bar member is a solid member having a passage therein extending substantially between said second end and said preselected location; and said line extends loosely through said passage and extends out of the passage adjacent said second end of the bar member.
