Endotracheal tube
First Claim
Patent Images
1. An endotracheal tube adapted for insertion through the oral or nasal passage of a patient to provide a passage for artificial respiration comprising:
- an elongated, flexible air tube having a proximal end portion adapted to be located external to the patient and a distal end portion adapted to be located within the trachea;
means for sealing the air tube with respect to the trachea, said sealing means being capable of sealing the trachea at a point spaced from the subglottis; and
cushioning means covering at least a portion of the external wall surface of said air tube and being located such that on insertion of said tube in said patient said cushioning means lies between the cricoarytenoid joint and said external wall surface of said air tube to prevent contact of said air tube with the cricoarytenoid joint to reduce the incidence and severity of cricoarytenoid trauma.

Abstract
An endotracheal device comprises an air tube adapted to be inserted through the oral or nasal passage and into the trachea to provide an air passage for respirating a patient. The air tube includes an inflatable cuff mounted at the distal end, and a membrane containing a cushioning material disposed along the air tube adjacent the cuff in a position to prevent direct contact between the air tube and the cricoarytenoid joint and its surrounding tissues.

6. An endotracheal device for respirating a patient comprising:
-
a flexible air tube having a proximal end, distal end and outer surface, said air tube being adapted for insertion through the oral or nasal passage and into the trachea of the patient with said distal end being disposed within said trachea, said air tube providing a passage for respiration of the patient; a first air-inflatable cuff adjacent said distal end of said tube, said cuff being inflatable to create a seal between said air tube and said trachea when inserted in the patient, said cuff being capable of sealing the trachea at a point spaced from the subglottis; and a second cuff covering at least a portion of said outer surface of said air tube, said second cuff being positioned along said air tube such that on insertion of said tube in said patient said second cuff lies between the cricoarytenoid joint and said outer surface of said air tube to prevent contact of said air tube with the cricoarytenoid joint to reduce the incidence and severity of cricoanytenoid trauma. - View Dependent Claims (7, 8, 9, 10, 11)
