Nasal Ventilation Cannula System and Methods
First Claim
1. A ventilation apparatus comprising a nasal ventilation cannula, and gas delivery system, wherein the ventilation cannula comprises:
- a. A proximal end adapted to attach to the gas delivery system and a distal end adapted to engage with the nares,b. A sensing tube comprising a distal end configured to enter a nostril, a medial aspect directed toward the nostril septum, a lateral aspect directed toward the nostril lateral wall, an anterior aspect directed away from the skin, and a posterior aspect directed toward the skin,c. A gas delivery channel comprising a distal end coupled to the lateral aspect of sensing tube and terminating with a gas delivery nozzle at the distal end.

Abstract
A nasal cannula ventilation system is described for treating lung disease or for exercise conditioning, incorporating a Venturi system. The ventilation cannula comprises unique positioning features to positively locate a gas delivery nozzle in an optimal location to optimize Venturi performance, patient comfort and fitment to the patient. The cannula is low profile, making it as realistic to wear and use as a standard oxygen cannula, and is simple rending the cost reasonable. The ventilation cannula uses a simple low cost ventilator as a gas delivery control system which is compatible with existing gas sources. The system is used (1) during stationary use to unrest the respiratory muscles to increase tolerance to activity after a treatment session, or (2) to enable activity within a distance from a stationary gas source, (3) during ambulatory use using a portable gas source to enable mobility, and (4) for enhanced fitness conditioning.

a. A proximal end adapted to attach to the gas delivery system and a distal end adapted to engage with the nares; b. A sensing tube comprising a distal end configured to enter a nostril, the distal end comprising a medial aspect directed toward the nostril septum, a lateral aspect directed toward the nostril lateral wall, an anterior aspect directed away from the skin, and a posterior aspect directed toward the skin, c. A gas delivery channel comprising a distal end coupled to the lateral aspect of sensing tube and terminating with a gas delivery nozzle at the distal end; and wherein the gas exiting the gas delivery nozzle creates an expanding gas flow profile entering the nostrils, and wherein the distal end of the sensing tube comprises an indentation along the outside of the tube which is configured to allow clearance for the gas flow profile. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 17, 18, 19, 20)
