  • Patent number: 8881731
    Abstract: A respiratory mask system is provided, in which while wearing a respiratory mask system, force generated by movement of a user's head and the like to induce laterally slipping a mask cushion may be reduced or absorbed. The respiratory mask system is provided with a mask cushion covering a nose, a nose and a mouth, or a full face. A first frame is connected with the mask cushion to supply respiratory gas under positive pressure. A second frame is connected with a headgear strap, in which the mask cushion is placed on a face side of the first frame and the first frame is placed on a face side of the second frame. The first frame is connected slidably with the second frame along a slide surface.

  • Patent number: 8393327
    Abstract: A headgear suitable for wearing a respiratory mask system wearing on the head of a user is provided, wherein it can be easily manufactured, the leakage of the positive pressure gas when pressurized is reduced, and a good wearing feel is achieved. The headgear is adapted to secure a respiratory mask, which contacts the face of the user to supply a positive pressure gas for respiration to the user, to the head of user. The headgear has a head mounted portion which is worn on the occipital of the user and a strap (3) connecting to this head mounted portion. The head mounted portion has at least one closed curved belt (1) which has thereon at least one junction (2). At least one junction provides the closed curved belt with a nonplanar structure adaptable to the shape of the head of the user.

  • Publication number: 20090014008
    Abstract: According to the present invention, there is provided a nasal respiratory mask contacting with the face of a user for supplying respiratory positive-pressure gas to the nose of the user, comprising at least a part attached tightly to the face that is attached tightly to the face of the user; a frame-fitting part for fitting to a frame; and an elastic connecting part that connects elastically the part attached tightly to the face with the frame-fitting part, wherein a facial side of the elastic connecting part is kept apart from the frame-fitting part side thereof for a required distance even in the absence of applied respiratory positive pressure. The nasal respiratory mask has advantages that it can be worn in an appropriate position without applying positive pressure at the start of wearing, scarcely disturbs the visual field during wearing, and can prevent prolongation of the time required for drying or occurrence of unsanitary condition after routine cleaning by washing with water.
