Abstract
A tube for delivering fluid that has a tube extending between a first opening and a second opening, an expandable cuff formed on a distal end of the tube, a resistant member formed around a portion of the tube, and a sleeve formed around the resistant member. Wherein, the sleeve presents a substantially smooth outer surface.
Claims21
An endotracheal tube assembly, comprising:
- an airway tube forming a fluid channel from a first opening to a second opening and defining a tube wall;
- a resistant member formed around a portion of the airway tube;
- a sleeve formed around the resistant member;
- and
- a first cuff formed along the airway tube proximate to the second opening;
- wherein, the sleeve is formed of a single material having a substantially smooth outer surface,
- wherein the sleeve and the resistant member have a first hole there through at a location proximate to a first inflation lumen and the airway tube has a second hole partially there through, the second hole aligned with the first hole;
- wherein an adhesive fluidly seals a perimeter of the first hole to fluidly couple the first cuff to the first inflation lumen such that fluid from the first inflation lumen is prevented from entering a space between the airway tube and the sleeve.
5 more elements
A method for manufacturing an endotracheal tube, comprising:
- forming an airway tube with at least two inflation lumen passageways defined in a wall of the airway tube;
- winding a resistant member around an outer portion of the airway tube;
- expanding a sleeve and positioning the sleeve around the resistant member;
- allowing the sleeve to contract to thereby compress the resistant member against the airway tube;
- cutting a first hole through the sleeve and the resistant member at a location proximate to one of the at least two inflation lumen passageways;
- cutting a second hole partially through the airway tube, the second hole aligned with the first hole;
- applying an adhesive along a perimeter of the first hole;
- and
- coupling a proximal and distal cuff to the airway tube and fluidly coupling one of the two inflation lumen passageways to one of the proximal and distal cuff through the second hole.
6 more elements
A method of coupling a cuff to an inflation lumen for an endotracheal tube, comprising:
- providing an endotracheal tube having an inflation lumen defined therein, a resistant material positioned around at least a portion of the endotracheal tube, and a sleeve positioned around at least a portion of the resistant material;
- cutting a first hole through the sleeve and the resistant material at a location proximate to the inflation lumen;
- cutting a second hole partially through the endotracheal tube, the second hole aligned with the first hole;
- inserting a stopper into the second hole and applying an adhesive around the stopper along a perimeter of the first hole;
- removing the stopper and coupling the cuff along the endotracheal tube to fluidly couple the cuff to the inflation lumen through the second hole.
