Methods, systems and devices for non-invasive open ventilation with gas delivery nozzles within an outer tube

摘要

A non-invasive ventilation system may include at least one outer tube with a proximal lateral end of the outer tube adapted to extend to a side of a nose. The at least one outer tube may also include a throat section. At least one coupler may be located at a distal section of the outer tube for impinging at least one nostril and positioning the at least one outer tube relative to the at least one nostril. At least one jet nozzle may be positioned within the outer tube at the proximal lateral end and in fluid communication with a pressurized gas supply. At least one opening in the distal section may be adapted to be in fluid communication with the nostril. At least one aperture in the at least one outer tube may be in fluid communication with ambient air. The at least one aperture may be in proximity to the at least one jet nozzle.

1. A non-invasive ventilation system, the system comprising:
at least one outer tube with a proximal lateral end of the at least one outer tube adapted to extend to a side of a nose, wherein the at least one outer tube includes a wall and a throat section; at least one coupler at a distal section of the at least one outer tube for impinging at least one nostril and positioning the at least one outer tube relative to the at least one nostril; at least one jet nozzle positioned within the at least one outer tube at the proximal lateral end and in fluid communication with a pressurized gas supply; at least one pressure tap disposed within the at least one outer tube in fluid communication with a transducer; at least one opening in the distal section adapted to be in fluid communication with the at least one nostril; and at least one aperture defined through the wall of the at least one outer tube in fluid communication with ambient air, wherein the at least one aperture is in downstream proximity to the at least one pressure tap.
