Description

FIELD OF THE INVENTION[0001]The present invention relates generally to medical devices, methods, and kits. More particularly, the present invention relates to improved endotracheal tubes or patient ventilation tubes which prevent the leakage of proximal secretions to the distal airways.BACKGROUND OF THE INVENTION[0002]Mechanical ventilation by placement of endotracheal and other ventilation tubes can be a necessity for patients for a variety of reasons. For example, patients receiving anesthetics may require ventilation to temporarily take over their natural breathing mechanism. Here mechanical ventilation is used only for a relatively short period of time. Patients suffering from respiratory failure, in contrast, may be intubated and ventilated for days, weeks, or even longer while in intensive care. Ventilation tubes which enter the trachea through a patient's mouth or nose are generally referred to as endotracheal tubes. Ventilation tubes which are inserted through an incision in...

AI Technical Summary

Benefits of technology

The present invention provides improved ventilation devices and methods for ventilating patients. Specifically, it provides ventilation tubes that prevent the leakage of proximal secretions to the distal airways. Unlike conventional double-cuffed systems, the present invention achieves this by using a continuous positive pressure in the region between the primary and secondary cuffs. This positive pressure acts as a barrier to reduce further leakage of secretions and allows them to move uward and be easily aspirated. The invention also includes a pressurization lumen for continuously measuring and adapting pressure in the inter-cuff chamber. Overall, the invention improves ventilation by preventing leakage of secretions and promoting airflow.

Problems solved by technology

The occurrence of VAP leads to increased duration of ventilation and ICU stay and is associated with a high attributable mortality.

VAP also leads to more and specific antibiotic use, increasing the risk of development of multidrug resistant bacteria.

In spite of the use of these new types of endotracheal or tracheostomy tubes, the leakage of the proximal secretions to the distal airways still occurs.
