Abstract

A system for reducing airway obstructions of a patient may include a ventilator, a control unit, a gas delivery circuit with a proximal end in fluid communication with the ventilator and a distal end in fluid communication with a nasal interface, and a nasal interface. The nasal interface may include at least one jet nozzle, and at least one spontaneous respiration sensor in communication with the control unit for detecting a respiration effort pattern and a need for supporting airway patency. The system may be open to ambient. The control unit may determine more than one gas output velocities. The more than one gas output velocities may be synchronized with different parts of a spontaneous breath effort cycle, and a gas output velocity may be determined by a need for supporting airway patency.

Core Innovation

The disclosure describes an open nasal/non-invasive ventilation system that secures an open nasal interface to a patient using a left cannula and a right cannula connected to each other by an adjustable inter-connector that allows pivoting of respective distal ends. The distal ends are aligned with the patient’s left and right nostrils, and tubing is extended around the left and right ears to secure the nasal interface.

The system provides tubing coupled to the proximal ends of the left and right cannulas, where the tubing includes a ventilator gas delivery channel and a pressure tap conduit. The nasal interface includes a nozzle for each cannula that delivers ventilation gas from the tubing to the cannula.

The disclosure also describes the arrangement as supporting a method that administers ventilation therapy to a patient via the same nasal interface configuration, with ventilation gas delivered through the ventilator gas delivery channel of the tubing and the cannulas via the respective nozzles.

Claims Coverage

The independent claim set comprises 2 independent methods. Across the independent claims, there are recurring inventive features centered on an adjustable pivoting inter-connector, ear-extended securing tubing with a ventilator gas delivery channel and a pressure tap conduit, and nozzle-equipped left and right cannulas that deliver ventilation gas.

Across both independent claims, the core coverage is the combined use of a pivoting adjustable inter-connector for nostril alignment, tubing that includes a ventilator gas delivery channel and a pressure tap conduit, ear-extended securing of the nasal interface, and nozzle-equipped left and right cannulas for delivering ventilation gas from the tubing to the patient.
