The retaining element is configured to support the patient interface structure in sealing engagement with the face of the patient. The retaining element includes an adhesive and/or at least one strap. In addition, the patient interface structure is configured to be released from and re-engaged with the retaining element for re-positioning of the patient interface structure relative to the patient's face in a plurality of positions while the retaining element remains supported by the patient. ## Claims ### Claim 1 A patient interface system for delivering a flow of breathable gas to a patient, comprising: a patient interface support structure configured to be connected to a hose that delivers the flow of breathable gas; a pair of nasal pillows supported by the patient interface support structure, wherein each nasal pillow is configured to seal against an interior of the patient's nares; a support member configured to engage a bridge of the patient's nose; and a connecting member configured to connect the support member and the patient interface support structure, wherein said pair of nasal pillows is selectively repositionable in a plurality of positions relative to the support member while remaining engaged with the patient's nares. ### Claim 2 (depends on 1) A patient interface system according to claim 1, wherein each pillow comprises a bellows. ### Claim 3 (depends on 1) A patient interface system according to claim 1, wherein each pillow comprises a textured outer surface. ### Claim 4 (depends on 1) A patient interface system according to claim 1, wherein each pillow is received in an opening in the patient interface support structure and is removable from the opening. ### Claim 5 (depends on 1) A patient interface system according to claim 1, further comprising an upper lip support configured to support the patient interface support structure against the patient's upper lip. ### Claim 6 (depends on 1) A patient interface system according to claim 1, wherein the connecting member and the patient interface support structure are integrally formed. ### Claim 7 (depends on 1) A patient interface system according to claim 1, wherein the connecting member comprises a pair of slots configured to receive ends of a strap or straps. ### Claim 8 (depends on 1) A patient interface system according to claim 1, further comprising an elastic membrane connected to the pair of nasal pillows, wherein the elastic membrane is configured to be inflated by an increase of pressure in the patient interface support structure from receipt of the flow of breathable gas. ### Claim 9 (depends on 8) A patient interface system according to claim 8, further comprising an elastic membrane support connected to the elastic membrane. ### Claim 10 (depends on 9) A patient interface system according to claim 9, further comprising a stop connected to the elastic membrane support that is configured to limit inflation of the elastic membrane. ### Claim 11 (depends on 1) A patient interface system according to claim 1, wherein the support member is separable from the connecting member.
