1. A sealing arrangement for use in a patient interface device for delivering a flow of breathing gas to an airway of a patient, the sealing arrangement comprising:
(a) a nasal pillow having a sealing surface structured to sealingly engage a surface of the patient at or about the airway;
(b) a first magnetic material disposed in or on the nasal pillow;
(c) a carrier member structured to be positioned across a nose of the patient; and
(d) a second magnetic material positioned in or on the carrier member, wherein the first magnetic material and the second magnetic material are positioned and structured to magnetically interact in a manner that the sealing surface of the nasal pillow toward the surface of the patient, responsive to the nasal pillow being disposed at or about the airway and the second magnetic material is disposed at a corresponding position to interact with the first magnetic material, wherein the nasal pillow comprises a third magnetic material positioned therein or thereon which is positioned and structured to interact with a magnetic material of another nasal pillow in an attractive manner when the nasal pillow engaged with a naris of the patient, and wherein the third magnetic material is positioned and structured to interact with the first magnetic material in a repulsive manner.
