    摘要： A sealing arrangement for forming a seal between a patient's face and a patient interface device for use in delivering a flow of a treatment gas to the patient includes a generally planar substrate body having a first side and an opposite second side. The substrate body includes a main portion having an opening defined therethrough that is sized and configured to encompass the mouth and nose of the patient. The sealing arrangement further includes a first adhesive layer disposed on the first side of the substrate body and a second adhesive layer disposed on the second side of the substrate body. The first adhesive layer is sized and configured to adhere to the skin of the patient with a first adherence force and the second adhesive layer is sized and configured to adhere to a cushion of the patient interface device with a lesser second adherence force.

    摘要： A heat and moisture exchanger (HME) for engaging a patient's nose while retrofit into a plenum chamber of a patient interface. The HME includes a frame configured to couple to a ridge of the patient's nose, and a cradle coupled to the frame. The cradle is configured to be positioned proximate to the patient's nares. The HME also includes an HME material coupled to the cradle. The HME material is configured to retain moisture exhaled by the patient. Air is configured to pass through the HME material when entering and exiting the patient's nares. The HME engages and is secured to the patient's nose independently of any other structure.

    摘要： A nasal interface uses asymmetrical nasal delivery elements to deliver an asymmetrical flow through the interface to both nares or to either nare, and a mouthpiece may be inserted to maintain a leak, to improve dead space clearance in the upper airways, decrease peak expiratory pressure, reduce noise, increase safety of the therapy for smaller patients and reduce resistance in the interface allowing desired flow rates to be achieved at reduced motor speeds of associated flow generating devices. Different forms of fittings, such as sleeves or inserts can be attached to nasal delivery elements to improve or optimize the therapeutic effects of nasal high flow. It may allow high pressures to be achieved at lower flow rates, reduce noise, improve patient comfort and efficiently clear anatomical dead space.
