Abstract
A nasal or full-face mask frame includes a main body and a vent assembly provided to the main body. The vent assembly includes a plurality of holes arranged in at least one column. The holes are positioned on a relatively flat and/or non-recessed portion of the main body.
Claims64
A mask frame for a mask assembly useful for treating sleep disordered breathing of a patient, the frame comprising:
- a one-piece main body of molded polycarbonate material;
- and a vent portion adapted to allow washout of gases exhaled by the patient, the vent portion being provided to the main body, the vent portion including a plurality of holes of substantially circular cross section arranged in the polycarbonate material, wherein all of the holes extend through the molded material and are positioned on a continuous, substantially planar portion of the main body, the substantially planar portion containing all of the holes being positioned and aligned between an apex of the main body and an aperture to receive an elbow, the aperture being positioned below the apex, the continuous, substantially planar portion containing all of the holes being laterally centered with respect to the apex, wherein at least a part of the substantially planar portion is not substantially recessed with respect to surrounding portions of the frame and the holes of the vent portion are grouped on the substantially planar portion, so that gas exiting the holes will avoid interference with the frame, thereby helping to reduce noise;
- and wherein the substantially planar portion is positioned on the main body at a location generally corresponding to a nasal bridge of a patient when the mask frame is positioned on a face of the patient.
A mask frame for a mask assembly useful for treating sleep disordered breathing of a patient, the mask frame comprising:
- a one piece main body comprising molded polycarbonate material, said main body having a bore adapted to engage an elbow assembly, said main body defining a vertically oriented longitudinal axis extending across a center of the bore, said main body having a continuous vent surface intersecting the longitudinal axis as seen in front view and being positioned superior to the bore, the vent surface being substantially planar as seen in a cross-section taken perpendicular to the longitudinal axis;
- and a pattern of holes adapted to allow washout of gases exhaled by the patient, the pattern of holes being arranged in at least one substantially vertical column positioned on said continuous, substantially planar vent surface, said column extending substantially parallel to the longitudinal axis, all of said holes extending through the molded polycarbonate material and being positioned on the continuous, substantially planar vent surface, wherein at least a part of the substantially planar vent surface is not substantially recessed with respect to surrounding portions of the frame and the vent surface is positioned and oriented on the main body, so as to reduce noise-inducing interference between gas exiting the holes and adjacent portions of the main body.
A mask frame assembly for a mask assembly useful for treating sleep disordered breathing of a patient, comprising:
- a one piece main body having a bore extending through polycarbonate material;
- an elbow received within the bore;
- and a pattern of gas washout vent holes of substantially circular cross section adapted to allow washout of gases exhaled by the patient, the pattern of holes extending through polycarbonate material of the one piece main body, each of said holes being provided on a continuous, substantially planar surface aligned between an apex of the main body and the bore, the bore being positioned below the apex, the continuous, substantially planar surface containing all of the vent holes and being laterally centered with respect to the apex, wherein at least a part of the substantially planar surface is not substantially recessed with respect to surrounding portions of the frame so as to avoid noise inducing interference between gas exiting from the holes and the surrounding portions of the frame;
- and wherein the substantially planar surface is positioned at a location on the main body adapted to correspond to a nasal bridge of a patient when the mask frame is positioned on a face of the patient.

A full face mask assembly for treating sleep disordered breathing of a sleeping patient, the mask assembly comprising:
- a molded polycarbonate frame;
- a silicone cushion attached to the frame and adapted to form a seal with the patient's face;
- an elbow assembly adapted to connect to an air delivery tube to deliver gas to the patient;
- a forehead support;
- and a headgear assembly, wherein the frame comprises:
- a main body;
- an upper support member that supports the forehead support;
- lower headgear anchor points adapted to anchor straps of the headgear assembly;
- a lower bore that engages the elbow;
- and a vent assembly positioned proximate an apex of the main body and aligned between the lower bore and the upper support member, the vent assembly comprising:
- a continuous vent surface proximate the apex and being inclined such that when the mask assembly is mounted on a patient's face, the vent surface faces upward and away from the patient's face;
- and a plurality of holes of substantially circular cross section adapted to washout gases exhaled by the patient, all of the holes being arranged in a grouping and positioned on the continuous vent surface, at least some of the plurality of holes being offset from other holes within the grouping, wherein a length of the vent surface in a direction parallel to the longitudinal axis of the frame is longer than a width of the vent surface in a direction perpendicular to the longitudinal axis of the frame, wherein at least a part of the vent surface is not substantially recessed with respect to surrounding portions of the frame so as to avoid noise inducing interference between gas exiting from the holes and the surrounding portions of the frame.

A mask assembly for treating sleep disordered breathing of a patient, the mask assembly comprising:
- a molded polycarbonate frame;
- a cushion adapted to form a seal with the patient's face;
- a cushion clip that retains the cushion to the frame, the frame including a plurality of recesses to receive the cushion clip;
- an elbow assembly provided to the frame and adapted to connect to an air delivery tube to deliver gas to the patient;
- a forehead support;
- and a headgear assembly adapted to support the mask assembly proximate the user's face, wherein the frame comprises:

- a lower bore that engages the elbow;
- and a vent assembly adapted to allow washout of gases exhaled by the patient, the vent assembly being positioned superior to the lower bore, the vent assembly comprising:
- a flat and substantially smooth surface;
- and a plurality of holes of substantially circular cross section arranged through the flat and substantially smooth surface, wherein the holes of the vent assembly are not substantially recessed so as to avoid noise inducing interference between gas exiting from the holes and the adjacent portions of the frame.
