Conduit with magnetic connector

A patient interface comprising:

• a plenum chamber pressurisable to a therapeutic pressure of at least 6 cmH2O above ambient air pressure, said plenum chamber including a first plenum chamber inlet port and a second plenum chamber inlet port, each being sized and structured to receive a flow of air at the therapeutic pressure for breathing by a patient,
• a seal-forming structure constructed and arranged to form a seal with a region of the patient's face surrounding an entrance to the patient's airways, said seal-forming structure having a hole therein such that the flow of air at said therapeutic pressure is delivered to at least an entrance to the patient's nares, the seal-forming structure 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 to provide a force to hold the seal-forming structure in a therapeutically effective position on the patient's head, the positioning and stabilising structure comprising a tie, 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
• wherein the first plenum chamber inlet port includes a first plenum chamber magnet with a first polarity and the second plenum chamber inlet port includes a second plenum chamber magnet with a second polarity;
• wherein the positioning and stabilising structure includes a headgear conduit for directing air to the patient's nares at the therapeutic pressure, the positioning and stabilising structure comprising a first conduit connector assembly and a second conduit connector assembly, the first conduit connector assembly including a first connector magnet with the second polarity and a second connector magnet with the first polarity;
• wherein the first plenum chamber magnet is attracted to the first connector magnet and the first plenum chamber magnet repels the second connector magnet, and wherein the second plenum chamber magnet is attracted to the second connector magnet and the second plenum chamber magnet repels the first connector magnet;
• and
• wherein air is configured to pass from the first conduit connector assembly through the first plenum chamber inlet port and air is also configured to pass from the second conduit connector assembly through the second plenum chamber inlet port.
