Tracheal tubes
First Claim
Patent Images
1. A tracheal tube comprising:
- a tubular shaft curved along a part at least of its length;
a sealing cuff towards one end of the shaft;
a single suction lumen extending longitudinally along one side of said shaft along a part of the length of the shaft, said suction lumen having an opening just above an upper end of said cuff on an outside of said shaft; and
a recess in the outer surface of said shaft, said opening being located to one side of said recess and said recess extending laterally away from said opening to a location adjacent an outside curve of said shaft such that secretions collecting at the outside curve of said shaft can be removed via said recess and said suction lumen.

Abstract
A tracheostomy tube has a sealing cuff inflated by an inflation tube extending in a channel along one side of the tracheostomy tube. A suction tube extends in a channel along the opposite side of the tracheostomy tube. The suction tube extends to the upper end of the sealing cuff and opens into a recess on the outside of the tracheostomy tube through a side opening oriented at right angles to the radius of the tracheostomy tube. The recess extends around about 90° of the tube towards its outer curve so that secretions collecting in this region can be removed.

8. A tracheal tube comprising:
- a tubular shaft curved along a part at least of its length;
a sealing cuff towards one end of said shaft;
a single suction tube extending longitudinally along one side of said shaft, said suction tube being closed at its end and having a side opening just above an upper end of said cuff in the outer surface of said shaft; and
a recess on the outside of said shaft, said tube being located at one end of said recess and said recess extending laterally away from said opening to a location adjacent an outside curve of said shaft, wherein said side opening of said suction tube is oriented at substantially right angles to a radius of said shaft and opens into said recess such that secretions collecting at the outside curve of said shaft can be removed via said recess and said side opening of said suction tube.
