SECRETION CLEARING VENTILATION CATHETER AND AIRWAY MANAGEMENT SYSTEM

摘要

A pulmonary secretion clearing ventilation catheter and related airway management system is disclosed. The ventilation catheter 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 patent 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. An improved inflatable cuff is also disclosed that permits a slight air leakage in the pneumatic seal between the patient's lungs and the environment, thereby facilitating removal of pulmonary secretions from the patient's lungs.

主权项

1. A ventilation catheter configured to engage with the pre-pharyngeal/pharynx and intratracheal regions of an airway and for operably securing to an airway management system, the ventilation catheter comprising:
an open 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; a double lumen portion defining a first lumen pneumatically connected to provide an inspiratory fluid pathway for new inspiratory fluid and a second lumen pneumatically connected to provide an expiratory fluid pathway for used inspiratory fluid, the first lumen substantially parallel to the second lumen and configured to occupy the prepharyngeal/pharynx region; a single lumen portion formed from an intersection of the first lumen with the second lumen for protrusion into the intratreacheal region, the single lumen portion including an open distal end for allowing the new inspiratory fluid from the airway management system to flow into a patient and the used inspiratory fluid from the patient to flow back to the airway management system; and at least one.
