High flow therapy artificial airway interfaces and related methods
Embodiments of the present invention provide a device, system and method for providing high flow therapy interfaces for use in the treatment of respiratory conditions and in assisted respirations. In an embodiment of the invention, a nasal cannula for delivery of respiratory gases can include at least one nasal insert and at least one flange coupled to the at least one nasal insert where the at least one flange is configured to partially impede the egress of respiratory gasses delivered to an upper airway of a patient is provided. In another embodiment, a flange has a shape selected from the group consisting of a slotted, vented or slitted design and configured to partially impede the egress of respiratory gasses.
1. A nasal cannula for delivery of respiratory gases, the nasal cannula comprising:
at least one nasal insert; and
at least one flange coupled to the at least one nasal insert, the at least one flange configured to partially impede the egress of respiratory gasses delivered to an upper airway of a patient, wherein the at least one flange includes a top surface defining a corresponding top surface area,
wherein the at least one flange further includes at least one slot defining a corresponding implicit surface area, the top surface area of the top surface being substantially greater than the implicit surface area of the at least one slot; and
a flange retention connector configured to receive a detachable flange.
2. The nasal cannula of claim 1 , wherein the flange is configured to fit within the nostril of a patient.
3. The nasal cannula of claim 1 , wherein the flange is configured to fit outside the nostril of a patient.
4. The nasal cannula of claim 1 , wherein the nasal insert has two lumens.
5. A flange for a nasal cannula, the flange configured to detachably couple to a flange retention connector, the flange configured to partially impede the egress of respiratory gasses, wherein the at least one flange includes a top surface defining a corresponding top surface area, and wherein the at least one flange further includes at least one slot defining a corresponding implicit surface area, the top surface area of the top surface being substantially greater than the implicit surface area of the at least one slot.
6. The flange of the nasal cannula of claim 5 , wherein the flange is configured to fit within the nostril of a patient.
7. The flange of the nasal cannula of claim 5 , wherein the flange is configured to fit outside the nostril of a patient.
