Positive airway pressure (PAP) mask
A flexible positive airway pressure (PAP) mask body, frame, and cushion are described. The mask body includes prongs that insert through and act upon apertures of the mask frame to connect the mask frame to the mask body. An airtight seal may be created between the mask body and the mask frame by a ball and socket connector, of the mask frame, having an elongated portion that extends through and has an outer perimeter commensurate with an aperture located in the mask body. The mask body may be configured with elongated portions that extend from the mask body chamber and to ends of eye sockets of the user. Headgear may couple to end portions of the mask frame corresponding to the elongated portions of the mask body. When pulling pressure by the headgear, additional contact is created between elongated portions of the mask cushion and the user's face.
1 . A positive airway pressure (PAP) mask assembly comprising:
a mask frame including a concave surface including a first aperture and a second aperture therein, the mask frame further including an extension element extending from the concave surface;
a mask body formed from a polyvinyl chloride, the mask body comprising a convex surface, a first prong and a second prong each extending outwardly from the convex surface, and a third aperture in the convex surface; and
a mask cushion coupled to the mask body, the mask cushion comprising a gel,
wherein a distance between the first prong and second prong is reduced when a force is applied to the convex surface of the mask body,
wherein the first prong and the second prong are configured to be inserted through the first aperture and the second aperture, respectively, when the distance is reduced,
wherein the first prong and the second prong are configured to act upon the first aperture and the second aperture, respectively, to removably connect the mask body to the mask frame, and
wherein the extension element of the mask frame is configured to be inserted through and provide a seal with the third aperture of the mask body when the first prong and the second prong act upon the first aperture and the second aperture, respectively.
2 . The PAP mask assembly of claim 1 , wherein the mask frame further includes a socket portion of a ball and socket connector.
3 . The PAP mask assembly of claim 1 , wherein:
the mask frame further includes a convex surface; and
the first prong and the second prong are configured to be inserted through the first aperture and the second aperture, respectively, when a force is applied to the convex surface of the mask frame.
4 . The PAP mask assembly of claim 3 , wherein a distance between the first aperture and the second aperture is increased when the force is applied to the convex surface of the mask frame.
5 . The PAP mask assembly of claim 1 , wherein the mask body is configured to fit over at least a portion of a nose of a user.
6 . The PAP mask assembly of claim 1 , wherein the mask body is configured to fit over a mouth and at least a portion of a nose of a user.
7 . The PAP mask assembly of claim 1 , wherein the mask body further includes a retaining element therein, the retaining element being configured to reshape and retain the convex surface of the mask body to features of a face of a user.
8 . A mask frame for a positive airway pressure (PAP) mask assembly, the mask frame comprising:
a concave surface;
a convex surface
a first aperture within the concave surface, the first aperture configured to receive a first prong extending from a convex surface of a mask body;
a second aperture within the concave surface, the second aperture configured to receive a second prong extending from the convex surface of the mask body; and
an extension element extending from the concave surface,
wherein the mask frame is configured to removably connect to the mask body when the first aperture and the second aperture are acted upon by the first prong and the second prong, respectively,
wherein the extension element is configured to be inserted through and provide a seal with a third aperture of the mask body when the first aperture and the second aperture are acted upon by the first prong and the second prong, respectively,
wherein the first aperture and the second aperture are configured to receive the first prong and the second prong, respectively, when a force is applied to the convex surface of the mask frame,
wherein a distance between the first aperture and the second aperture is increased when the force is applied to the convex surface.
9 . The mask frame of claim 8 , further comprising a socket portion of a ball and socket connector.
10 . The mask frame of claim 8 , wherein the mask frame is constructed using a thermoplastic polymer.
11 . The mask frame of claim 10 , wherein the thermoplastic polymer is polypropylene.
12 . The mask frame of claim 8 , wherein the mask frame is constructed using polyvinyl chloride.
