SECRETION CLEARING PATIENT AIRWAY MANAGEMENT SYSTEM
First Claim
1. A airway structure for operably securing a patient to an airway management system that has a new inspiratory fluid path and an expiratory fluid path, said airway structure having:
- an opening toward a distal end for allowing new inspiratory fluid from the airway management system to flow into a patient and used inspiratory fluid from the patient to flow back to the airway management system;
a double lumen portion defining a first lumen and a second lumen, said double lumen portion sized to be received within a patient'"'"'s mouth and extend into the patient'"'"'s throat;
said first lumen pneumatically connected to the new inspiratory fluid path; and
,said second lumen pneumatically connected to said expiratory fluid path.

Abstract
A pulmonary secretion clearing airway structure and related airway management system is disclosed that has a double lumen portion which each lumen of the double lumen portion operably secured to an airway management system so that inspiratory fluid (air/oxygen mixtures, with or without added water vapor) is delivered to the distal end of the ventilation catheter through one of the two lumens and expired inspiratory fluid, pulmonary secretions, and pulmonary fluids are removed from the patient through the other lumen. The expiratory fluid pathway preferably includes a secretion collection system for removing the pulmonary secretions and the like from the pathway, thereby improving operation and safety of the system. The airway structure can be a ventilation catheter or a supraglottic airway system such as laryngeal mask and the like.
