    摘要： The present invention discloses a positioning and stabilising structure for a patient interface for delivery of a supply of pressurized air or breathable gas to a patient's airways, the positioning and stabilising structure comprising: a first spacer fabric strap portion including: a first fabric layer; a second fabric layer; a central fabric layer between the first fabric layer and the second fabric layer; and an unbroken loop layer on the second fabric layer such that the second fabric layer is between the central fabric layer and the unbroken loop layer, wherein the central fabric layer, the first fabric and the second fabric are warp/weft knitted together, and wherein the unbroken loop layer comprises loops and is configured to fasten to hooks of a hook and loop fastener to enable length adjustment of the positioning and stabilising structure; a second spacer fabric strap portion, the second spacer fabric strap portion including: a third fabric layer; a fourth fabric layer; a second central fabric layer between the third fabric layer and the fourth fabric layer, wherein the second spacer fabric strap portion omits unbroken loops, and wherein the second central fabric layer, the third fabric layer and the fourth fabric layer are warp/weft knitted together, and wherein the first spacer fabric strap portion has 6% to 10% elongation when a 10 Newtons force is applied, and wherein the second spacer fabric strap portion has 10% to 20% elongation when a 10 Newtons force is applied.

    摘要： A patient interface comprises: a plenum chamber (3200) pressurisable to a therapeutic pressure above ambient air pressure, said plenum chamber including a plenum chamber inlet port sized and structured to receive a flow of air at the therapeutic pressure for breathing by a patient; a seal-forming structure (3100) constructed and arranged to seal with a region of the patient's face surrounding an entrance to the patient's airways, said seal-forming structure being constructed and arranged such that the flow of air at said therapeutic pressure is delivered to an entrance to the patient's nares, and the seal-forming structure being constructed and arranged to maintain said therapeutic pressure in the plenum chamber throughout the patient's respiratory cycle in use; a positioning and stabilising structure configured to hold the seal-forming structure in a therapeutically effective position on the patient's head, the positioning and stabilising structure comprising a tie, and the tie being constructed and arranged so that at least a portion overlies a region of the patient's head superior to an otobasion superior of the patient's head in use; and a vent structure formed in the plenum chamber and configured to allow a continuous flow of gases exhaled by the patient from an interior of the plenum chamber to ambient; wherein the patient interface is configured to leave the patient's mouth uncovered during therapy, wherein the seal-forming structure is shaped and dimensioned such that no portion of the seal-forming structure enters into the patient's nares during use, wherein the seal-forming structure (3100) comprises two lateral support regions (3112.3; 3117), each located at a lateralmost side of the seal-forming structure (3100), and a medial region (3112.1; 3113, 3115) positioned between the lateral support regions, the naris openings passing through the seal-forming structure at the medial region, wherein the lateral support regions (3112.3; 3117) are thicker than the medial region (3112.1; 3113, 3115), and
    wherein the seal-forming structure further comprises two mid-lateral regions (3112.2), each of the mid-lateral regions being positioned laterally outward from and adjacent to the medial region and medially inward from and adjacent to a corresponding one of the lateral support regions, the mid-lateral regions being thicker than the medial region and thinner than the lateral support regions.
