    摘要： A patient interface is described which is reduces the pressure of the mask on the users face. The patient interface has a sealing interface having an inner sealing member and an outer sealing member. The inner and outer sealing members are adapted to seal around the facial contours of a user providing a sealed fluid communication to the user's respiratory tract. The inner and outer sealing members are at least continuously in contact with each other around the portions where the sealing interface contacts the user's facial contours. The inner sealing member may be provided with cut outs to provide additional flexibility to particular areas, such as the nasal bridge, upper lip or cheek regions and may be provided with a contoured edge to better fit the facial contours of a user.

    摘要： A respiratory humidifier chamber for use with a breathing assistance apparatus is described. The chamber comprises a water-tight vessel having an inlet for receiving gases from the breathing assistance apparatus, and an outlet through which heated humidified gases exit the vessel for delivery to a patient. The chamber has a partition which divides the chamber into upstream and downstream sub-chambers. The sub-chambers are separated by the partition except for an aperture which passes through the partition and allows gaseous communication between the sub-chambers. The downstream sub-chamber includes a heater base which heats a volume of water contained within it The aperture is located above the volume of water. The upstream sub-chamber contains an internal heater which heats gases passing through it from the inlet to the aperture. At least part of the internal heater is located immediately adjacent the aperture.
