An improved trachea suction system includes a suction catheter with a high efficiency
suction control valve providing unobstructed fluid flow in its activated suction
applied mode for removal of viscous secretions at a low level of applied input
suction through the catheter. The valve also non-restrictive to air flow at the
distal tip of the catheter. The valve ideally part of a closed tracheal suction
system having a catheter isolator seal with a vortex action catheter cleaning chamber
located in front of the isolator seal which takes advantage of the high efficiency
characteristics of the suction control valve.
