HEADGEAR FOR BREATHING MASK

摘要

An interface assembly includes an interface, such as a mask, that is secured to a head using a headgear assembly. The headgear assembly can include at least one halo portion and a plurality of straps. The headgear assembly can include both a front halo portion and a rear halo portion. In some arrangements, the headgear and mask define an adjustable closed loop. In some arrangements, the headgear can include one or more rigid portions that contact the user's face to at least partially isolate a seal of the mask from tightening forces applied to the headgear. In some arrangements, the mask is an oral-nasal mask and the headgear applies a force to the mask comprising an upward force component. In some arrangements, the headgear can be contoured to the user's head.

主权项

1. An interface assembly, comprising:
a mask comprising a seal that surrounds and delivers a flow of breathing gas to a mouth and/or nose of a user; a headgear that secures the mask to the face of the user, the headgear comprising relatively rigid portions that contact the cheeks of the user and support the mask relative to the face of the user, the relatively rigid portions having sufficient rigidity to maintain a position of the mask and limit compression of the seal in response to tightening of the headgear, wherein the headgear further comprises an upper arm or strap extending rearwardly from each of the relatively rigid portions toward a location generally above the user's ear, and wherein the headgear further comprises a rear halo portion surrounding a parietal region of the user's head and coupled to the upper arms or straps, wherein a portion of the rear halo portion, the upper arms or straps, and the mask cooperate to form a front halo portion.
