Abstract: A diffuser element for use over a vent opening of a breathing assistance apparatus. In some configurations, the diffuser element is formed by knitting or weaving one or more threads together into an interlocking pattern. In some configurations, the diffuser pad has a first surface and an opposing second surface and at least the first surface includes a surface texture. Arrangements for coupling the diffuser element to a structure that defines or carries the vent are also disclosed.

Abstract: Headgear for a respiratory interface comprising multiple separate sections of material joined to form the headgear and different levels of resilient extensibility or stretchability in at least four different parts or straps of the headgear.

Abstract: One variation of a dynamic tactile interface includes a tactile layer defining a peripheral region and a deformable region adjacent the peripheral region; a substrate coupled to the peripheral region, a fluid conduit adjacent the deformable region, a fluid channel fluidly coupled to the fluid conduit, and a via fluidly coupled to the fluid channel and passing through the back surface; a bladder fluidly coupled to the via and the substrate; a structure adjacent a first side of the bladder; and a platen adjacent a second side of the bladder opposite the first side and compressing the bladder against the structure substantially perpendicular the longitudinal axis of the bladder and substantially parallel the substrate to displace fluid from the bladder and into the fluid channel to transition the deformable region from a retracted setting into an expanded setting.

Abstract: The dynamic tactile interface includes: a tactile layer defining a peripheral region and a deformable region adjacent the peripheral region and operable between a retracted setting and an expanded setting; a substrate including an attachment surface and coupled to the peripheral region and defining a fluid conduit adjacent the deformable region and a fluid channel fluidly coupled to the fluid conduit; a border region proximal a periphery of the substrate and defining a cavity configured to receive an instrument, the cavity supporting the instrument in a first configuration and releasing the instrument in a second configuration; and a bladder fluidly coupled to the fluid channel and coupled to the cavity, the instrument compressing a portion of the bladder in the first configuration to displace fluid from the bladder into the fluid channel to transition the deformable region from the retracted setting to the expanded setting.
