Abstract A patient interface, such as a nasal cannula, for delivering breathable gas to a user is disclosed. The interface includes a body configured to be positioned on a user’s face and one or more nasal prongs fluidly connected to a gas supply for insertion into, or directing gas toward, the user’s nares. The body incorporates at least one force- or movement-responsive element configured to react to forces or movements experienced in a first region of the interface. The element is deformable or articulated and operates to isolate, absorb, dampen, or otherwise reduce transfer of such forces or movements to other regions of the interface. This localised response stabilises the position of the nasal prongs relative to the nares, maintaining a desired therapy delivery configuration despite external disturbances or changes in facial geometry. The responsive element may comprise hinges, pivots, joints, or regions of preferential flexibility or deformation, and may be arranged, for example, in a bridge region between body portions. Multiple elements may be combined to provide coordinated responses. The interface thereby enhances comfort and positional stability during use. Abstract
