Abstract
Abstract Disposable endotrached tubes are provided, such tubes having an adapter portion integral with a body portion through a juncture, with a lumen of substantial constant diameter extending throughout the body portion and juncture, the lumen opening into the adapter through a region of generally nonturbulent flow. In one embodiment, the juncture portion is corrugated to provide a flexible connection at any desired angle between adapter and body portion.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
258 words
A unitary disposable endotracheal tube for insertion through the mouth or nose of a patient into the trachea during a surgical operation or the like, comprising: a gently curved body portion having a substantially constant outside diameter of a size such that said portion is adapted to fit in the trachea of the patient; an adapter portion at the end of said tube opposite said body portion, said adapter being suitable for atTaching said tube to surgical equipment, and said adapter having a maximum inside diameter approximately equal to said outer diameter of said body portion; a juncture portion joining said body portion with said adapter portion, said juncture portion being of a length greater than said adapter portion but less than said body portion, and said juncture portion gently curving in such a manner that the end of said juncture portion adjacent said body portion is axially aligned therewith while the end of said juncture portion adjacent said adapter is axially aligned with said adapter; a lumen of generally uniform diameter extending throughout said juncture and body portions of said tube, opening through a gently curved region of nonturbulent flow into said adapter at one end, and through a beveled opening in said body portion at the end of said tube opposite said adapter, the diameter of said lumen throughout said juncture and said body portion being not greatly smaller than said maximum diameter of said adapter; said body portion, said juncture and said adapter being constructed as an integral unit of a suitable synthetic polymeric material.
Claim 2
Dependent Claim
258 words
A unitary disposable endotracheal tube for insertion through the mouth or nose of a patient into the trachea during a surgical operation or the like, comprising: a gently curved body portion having a substantially constant outside diameter of a size such that said portion is adapted to fit in the trachea of the patient; an adapter portion at the end of said tube opposite said body portion, said adapter being suitable for atTaching said tube to surgical equipment, and said adapter having a maximum inside diameter approximately equal to said outer diameter of said body portion; a juncture portion joining said body portion with said adapter portion, said juncture portion being of a length greater than said adapter portion but less than said body portion, and said juncture portion gently curving in such a manner that the end of said juncture portion adjacent said body portion is axially aligned therewith while the end of said juncture portion adjacent said adapter is axially aligned with said adapter; a lumen of generally uniform diameter extending throughout said juncture and body portions of said tube, opening through a gently curved region of nonturbulent flow into said adapter at one end, and through a beveled opening in said body portion at the end of said tube opposite said adapter, the diameter of said lumen throughout said juncture and said body portion being not greatly smaller than said maximum diameter of said adapter; said body portion, said juncture and said adapter being constructed as an integral unit of a suitable synthetic polymeric material.
Claim 3
Dependent Claim
260 words
A unitary disposable endotracheal tube for insertion through the mouth or nose of a patient into the trachea during a surgical operation of the like, comprising: a gently curved body portion having a substantially constant outside diameter of a size such that said portion is adapted to fit in the trachea of the patient; an adapter portion at the end of said tube opposite said body portion, said adapter being suitable for attaching said tube to surgical equipment, and said adapter having a maximum inside diameter approximately equal to said diameter of said body portion; a juncture portion joining said body portion with said adapter portion, said juncture portion being of a length greater than said adapter portion but less than said body portion; said juncture portion being corrugated to provide a flexible connection at any desired angle between said adapter and said body portion, the outside diameter of said corrugated portion being not significantly greater than the outside diameter of either said body portion or said adapter, a lumen of generally uniform diameter extending throughout said juncture and body portions of said tube, opening through a gently curved region of nonturbulent flow into said adapter at one end, and through a beveled opening in said body portion at the end of said tube opposite said adapter, the diameter of said lumen throughout said juncture and said body portion being not greatly smaller than said maximum diameter of said adapter; said body portion, said juncture and said adapter being constructed as an integral unit of a suitable synthetic polymeric material.
