ENDOTRACHEAL TUBE WITH DUAL PORT SUBGLOTTIC SECRETION SUCTIONING
First Claim
1. An endotracheal tube assembly comprising:
- an elongate tube having an outer wall defining an outer surface, the tube defining an elongate central lumen and an elongate suction lumen;
an inflatable cuff attached on a distal end portion of the elongate tube;
the outer wall of the elongate tube defining an opening for the suction lumen proximate to a proximal end of the inflatable cuff; and
a diffuser cap positioned on a distal portion of the outer wall of the tube over the distal opening for the suction lumen to define a first suction opening having a normal vector parallel to a tangent to an outer circumference of a transverse cross-section of the outer wall of the tube next to said first suction opening.

Abstract
The present invention provides in some embodiments, an endotracheal tube with subglottic secretion suction and a detachable suction line. The endotracheal tube is an elongate tube having an outer wall defining an elongate central lumen and an elongate suction lumen. The outer wall also defines an opening to the suction lumen near a distal end of the endotracheal tube An inflatable cuff is attached near a distal end of the elongate tube. The shoulder of the inflatable cuff is inverted in order to increase the diameter of the cuff from its distal end to its proximal end. A diffuser cap is positioned over the opening to the suction lumen and defines a fluid flow path for secretions into the suction lumen through the opening to the suction lumen.

21. An endotracheal tube assembly comprising:
-
an elongate tube having an outer wall defining a generally cylindrical elongate central lumen and a generally cylindrical outer surface and also defining an elongate suction lumen, wherein the elongate tube has a longitudinal axis extending along the length of the tube and a transverse axis extending across the width of the tube; an inflatable cuff attached near a distal end of the elongate tube, wherein the inflatable cuff has a proximal end and a distal end; the outer wall of the elongate tube defining an opening for the suction lumen proximal to the proximal end of the inflatable cuff; and a diffuser ring positioned around the outer wall of the elongate tube such that the diffuser ring at least partially covers the opening for the suction lumen wherein the diffuser ring includes a first diffuser ring channel parallel to the longitudinal axis of the elongate tube and a second diffuser ring channel parallel to the transverse axis of the elongate tube. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)
