Intubating airway device

Abstract

An airway device for human or animal use includes an airway tube having a first end and a second end, the first end of which is surrounded by a laryngeal cuff configured to fit over the laryngeal inlet of a patient when in situ. The first end of the airway tube is provided with an intubating ramp configured to direct a tube inserted through the airway tube into the laryngeal inlet of the patient when in situ.

1 . An airway device for human or animal use comprising an airway tube having a first end and a second end, the first end of which is surrounded by a laryngeal cuff configured to fit over the laryngeal inlet of a patient when in situ, wherein the first end of the airway tube is provided with an intubating ramp configured to direct a tube inserted through the airway tube into the laryngeal inlet of the patient when in situ wherein the intubating ramp is provided with a groove which runs longitudinally along the full length of the intubating ramp from the first end to the second end of the longitudinal ramp. 
     
     
         2 . The airway device as claimed in  claim 1  wherein the intubating ramp is provided on the internal wall of the dorsal side of the airway tube. 
     
     
         3 . The airway device as claimed in  claim 1  wherein the first end of the airway tube is of greater diameter than the remainder of the airway tube. 
     
     
         4 . The airway device as claimed in  claim 1  wherein the internal wall of the ventral side of the airway tube is flattened. 
     
     
         5 . The airway device as claimed in  claim 1  wherein the intubating ramp is provided with a plurality of grooves. 
     
     
         6 . The airway device as claimed in  claim 1  wherein the tip of the laryngeal cuff is elongate. 
     
     
         7 . The airway device as claimed in  claim 1  wherein the tip of the laryngeal cuff is provided with a protrusion on the back dorsal side thereof. 
     
     
         8 . The airway device as claimed in  claim 1  wherein a side wall of the second end of the airway tube is provided with a supplementary gas inlet. 
     
     
         9 . The airway device as claimed in  claim 1  wherein the first end of the airway tube is of widened diameter or flared. 
     
     
         10 . The airway device as claimed in  claim 2  wherein the first end of the airway tube is of greater diameter than the remainder of the airway tube. 
     
     
         11 . The airway device as claimed in  claim 2  wherein the internal wall of the ventral side of the airway tube is flattened. 
     
     
         12 . The airway device as claimed in  claim 2  wherein the intubating ramp is provided with a plurality of grooves. 
     
     
         13 . The airway device as claimed in  claim 2  wherein the tip of the laryngeal cuff is elongate. 
     
     
         14 . The airway device as claimed in  claim 2  wherein the tip of the laryngeal cuff is provided with a protrusion on the back dorsal side thereof. 
     
     
         15 . The airway device as claimed in  claim 2  wherein a side wall of the second end of the airway tube is provided with a supplementary gas inlet. 
     
     
         16 . The airway device as claimed in  claim 3  wherein the first end of the airway tube is of widened diameter or flared. 
     
     
         17 . The airway device as claimed in  claim 3  wherein the internal wall of the ventral side of the airway tube is flattened. 
     
     
         18 . The airway device as claimed in  claim 3  wherein the intubating ramp is provided with a plurality of grooves. 
     
     
         19 . The airway device as claimed in  claim 3  wherein the tip of the laryngeal cuff is elongate. 
     
     
         20 . The airway device as claimed in  claim 3  wherein the tip of the laryngeal cuff is provided with a protrusion on the back dorsal side thereof.
