  • Patient interface systems
    Patent number: 10512745
    Abstract: A patient interface is configured to deliver a flow of pressurized breathable gas to a patient's airways. The patient interface includes a central portion with an opening configured to deliver the pressurized breathable gas to the patient's nares. A first stabilizing portion extends from the central portion and is structured to engage an outer side of a respective one of the patient's nostrils. A second stabilizing portion is opposite the first stabilizing portion and extends from the central portion. In addition, the second stabilizing surface is structured to engage an outer side of a respective one of the patient's nostrils. The central portion, the first stabilizing portion and the second stabilizing portion cooperate to form a U-shape configured to cradle the patient's nose so that the tip of the patient's nose remains exposed when the patient interface is mounted on the patient's face.
