Abstract
A respiratory interface device including a fluid coupling device having a main body and an exhalation plate having a plurality of vent holes, the exhalation plate being separate from and coupled to the main body. The present invention further relates to a fluid coupling device including an exhaust portion having a plurality of vent holes having a tapered shape. A set of the vent holes has an incident angle that radiates and originates from a common point. The present invention also relates to an exhalation mechanism including a plurality of vent holes defined by a continuous straight inner wall extending from an interior surface to an exterior surface wherein an exterior circumference of the vent hole is offset with respect to an interior circumference.
Claims10
A respiratory interface device, comprising:
- a first main body;
- and
- a fluid coupling device operatively coupled to the first main body, the fluid coupling device including a second main body, and an exhalation plate, the exhalation plate comprising vent holes, the exhalation plate being separate from and coupled to the second main body, the vent holes have an arrangement selected from a plurality of linear rows and a non-linear pattern having a plurality of non-linear rows, wherein each vent hole in the arrangement has an associated incident angle, and wherein for all of the vent holes in the arrangement, each incident angle originates from a single common point.
A fluid coupling device for a respiratory interface device, comprising:
- a main body;
- and
- an exhaust portion having vent holes having a tapered shape and the vent holes having an arrangement selected from a plurality of linear rows and a non-linear pattern having a plurality of non-linear rows, wherein each of the vent holes in the arrangement has an associated incident angle and wherein for all of the vent holes in the arrangement, each incident angle radiates and originates from a single common point.
An exhalation mechanism for a respiratory interface device, comprising:
- an interior surface;
- an exterior surface;
- and
- vent holes each extending from the interior surface to the exterior surface, the vent holes having an arrangement selected from a plurality of linear rows and a non-linear pattern having a plurality of non-linear rows, each of the vent holes being defined by a continuous straight inner wall extending from the interior surface to the exterior surface, each of the vent holes having an interior circumference at the interior surface and an exterior circumference at the exterior surface, wherein for each vent hole the exterior circumference thereof is offset with respect to the interior circumference thereof, and wherein each vent hole in the arrangement has an associated incident angle, and wherein for all of the vent holes in the arrangement, each incident angle originates from a single common point.
