Abstract
An airway ventilation device for insertion in an elongate body cavity is provided. The airway ventilation device includes an endotracheal tube and an inflation cuff. The inflation cuff is toroidal in shape and includes one or more recessed attachment zones which allow for movement of the endotracheal tube without breaking the seal between the inflation cuff and the elongate body cavity.
Claims19
An airway ventilation device for insertion in an elongate body cavity, the device comprising:
- a tube comprising a distal end, a proximal end, and at least two attachment zones;
- and
- a toroidal shaped inflation cuff comprising an outer surface, an inner surface, a distal end, a medial portion, and a proximal end, wherein the toroidal shaped inflation cuff is adapted to attach to the tube at the at least two attachment zones, wherein a first attachment zone, in comparison to the proximal end of the inflation cuff, is located at a distance further from the proximal end of the tube, and wherein a second attachment zone, in comparison to the distal end of the inflation cuff, is located at a distance further from the distal end of the tube and wherein the outer surface is in communication with the trachea upon inflation.
An airway ventilation device for insertion in an elongate body cavity comprising:
- a tube comprising a distal end, a proximal end, and at least one attachment zone;
- and
- a toroidal shaped inflation cuff comprising an outer surface, an inner surface, a distal end, a medial portion, and a proximal end, wherein the toroidal shaped inflation cuff is adapted to attach to the tube at the at least one attachment zone, wherein the at least one attachment zone, in comparison to the proximal end of the inflation cuff, is located at a distance further from the proximal end of the tube, and wherein the at least one attachment zone, in comparison to the distal end of the inflation cuff, is located at a distance further from the distal end of the tube and wherein the outer surface is in communication with the trachea upon inflation.
