Tracheal tube and ventilator system permitting endogenously-produced NO to be combined with respiratory gas
First Claim
1. A tracheal tube having a proximal end and a distal end adapted for insertion into a patient'"'"'s trachea with said distal end conducting, via a flow path between the proximal end and the distal end in the tracheal tube, a respiratory gas to a patient'"'"'s lungs, said tracheal tube having an input port, said input port comprising means for connecting an exterior of said tracheal tube to said flow path through said input port for causing gas, containing produced endogenously NO by a patient, to flow from a patient'"'"'s upper respiratory tract into said flow path during inspiration by a patient.

Abstract
A ventilator system and a tracheal tube, inserted into a patient'"'"'s trachea to carry gas to and from the lungs, permit a gas mixture containing endogenous NO, which is present in the upper respiratory tract, to be supplied to the lungs. The tracheal tube has a input port which forms a connection between the interior of the tracheal tube and the upper respiratory tract. The input port draws or forces an amount of the gas containing endogenous NO into the tracheal tube and this gas accompanies the respiratory gas into the lungs during inspiration.

16. A ventilation system comprising:
-
a tracheal tube having a proximal end and a distal end with a flow path therebetween, said distal end being adapted for insertion into a patient'"'"'s trachea; respiratory assist means, connected to said proximal end of said tracheal tube, for supplying respiratory gas to a patient'"'"'s lungs; a tubular arrangement having a first end adapted for insertion into a patient'"'"'s nostril for conveying a gas toward said first end during inspiration phases of a patient; and said tracheal tube having at least one gas communication path disposed at a predetermined distance from said distal end of said tracheal tube which connects an exterior of said tracheal tube with a flow path within said tracheal tube, said gas communication path causing gas, containing NO endogenously produced by a patient, to flow from a patient'"'"'s upper respiratory tract into said flow path during inspiration by a patient. - View Dependent Claims (17, 18, 19, 20)

21. A ventilation system comprising:
-
a tracheal tube having a proximal end and a distal end, said distal end being adapted for insertion into a patient'"'"'s trachea; respiratory assist means, connected to said proximal end of said tracheal tube, for supplying respiratory gas to a patient'"'"'s lungs through said tracheal tube along a respiratory gas path; a tubular arrangement having a first end adapted for insertion into a patient'"'"'s nostril and a second end in communication with said respiratory gas path said gas communication path causing gas, containing NO endogenously produced by a patient, to flow from a patient'"'"'s upper respiratory tract into said flow path during inspiration by a patient; and means for generating a gas flow from said first end of said tubular arrangement to said respiratory gas path during inspiration phases of a patient. - View Dependent Claims (22, 23)
