The intranasal sponges and moisturizing liquid prevents and treats both abrasions from the nasal cannula and excessive drying of the mucosa. This reduces the incidence of nosebleeds in patients using supplemental nasal oxygen. ## Claims ### Claim 1 A nasal air moisturizing device to be used with a nasal cannula having a pair of prongs for delivering gas to a patient's nostrils, said device comprising: an outer shell having an interior volume and a pair of apertures positionable over the pair of prongs of the nasal cannula; and a moisture absorbent material having a portion positioned within the interior volume of the shell and a pair of protrusions extending outwardly through the pair of apertures of the shell, wherein the protrusions are positioned over the pair of prongs of the nasal cannula when the shell is attached to the nasal cannula, wherein a portion of the moisture absorbent material positioned within the shell is configured to receive moisturizing liquid and the pair of protrusions of the moisture absorbent material are configured to be positioned in the patient's nostrils to release the moisturizing liquid into breathing gas being delivered through the pair of prongs. ### Claim 2 (depends on 1) The nasal air moisturizing device as in claim 1, wherein the interior volume is configured to hold a moisturizing liquid, wherein the moisture absorbent material receives moisturizing liquids. ### Claim 3 (depends on 1) The nasal air moisturizing device as in claim 1, wherein the two protrusions which extend outwardly through apertures in the shell have passages therethrough which are configured to be disposed of the pair of prongs when the shell is attached to the nasal cannula. ### Claim 4 (depends on 1) The nasal air moisturizing device as in claim 1, wherein the moisture absorbent material is at least partially disposed within the shell with protrusions extending outwardly through the shell. ### Claim 5 (depends on 1) The nasal air moisturizing device as in claim 1, wherein the moisture absorbent material comprises a sponge. ### Claim 6 A method for providing an interface between a nasal cannula and a patient, said method comprising: providing a nasal cannula having prongs suitable without modification for placement in the nostrils of a patient for delivering a breathing gas to the patient; placing an assembly comprising a shell having an interior volume, a pair of apertures and a moisture absorbent material within the interior volume over the prongs of the nasal cannula, wherein the prongs extend from the interior of the shell through the apertures to an exterior of the shell and are covered by protrusions of the moisture absorbent material; positioning the protrusions of the moisture absorbent material which cover the prongs of the nasal cannula in the patient's nostrils so that the moisture absorbent material provides a moisture permeable barrier between the prongs and mucosa of the patient's nostrils; delivering a breathing gas to the patient's nostrils through the prongs of the nasal cannula; and wherein the moisture absorbent material contains a moisturizing liquid, wherein the moisture absorbent material releases the moisturizing liquid into the mucosa and the breathing gas to inhibit drying of the nasal mucosa. ### Claim 7 (depends on 6) The method of claim 6, wherein the moisture permeable barrier between the prongs and mucosa inhibits or prevents abrasion of the nasal septum and nasal turbinates. ### Claim 8 (depends on 6) The method of claim 6, wherein the patient is suffering from septal ulceration and nosebleeds from prior use of supplemental oxygen. ### Claim 9 (depends on 6) The method of claim 6, wherein the protrusions are inserted into the nostrils together with the nasal cannula. ### Claim 10 (depends on 9) The method of claim 9, further comprising introducing the moisturizing liquid into the shell through a port after the nasal cannula has been placed on the patient. ### Claim 11 (depends on 10) The method of claim 10, wherein a nasal saline solution and/or a bacteriostatic/bacteriocidal solution is introduced through the port. ### Claim 12 (depends on 10) The method of claim 10, wherein the moisturizing liquid is introduced into the shell through a port periodically without removing the shell from the patient. ### Claim 13 (depends on 9) The method of claim 9, further comprising replacing the assembly of the shell and the moisture absorbent material over the nasal cannula without replacing the nasal cannula.
