Nasal interface for supplying respiratory gases in sleep apnoea
The patent US12042603B2 describes a patient interface designed to deliver respiratory gases effectively to users. Central to this interface is a gasket portion that channels the flow of gases, complemented by a pair of pillow portions that extend from the gasket. These pillow portions are engineered to receive and direct the gas flow to the user. Each pillow portion features an upper opening and a lower end connected to the gasket. A notable innovation in this design is the inclusion of at least one rib within the pillow portions, which serves to enhance rigidity and prevent collapse during use. The rib is strategically positioned to lie within the gas flow, with its curvature and varying height contributing to the overall functionality of the interface.
Further claims detail the structural characteristics of the rib, including variations in height and cross-sectional thickness along its length. The rib's design allows for increased thickness towards the inner side of the pillow portion, ensuring optimal support. Additionally, the rib can extend downward from the upper opening and may have a rounded shape that blends seamlessly with the pillow's inner side. The patent also specifies that the rib's cross-sectional thickness can be greater than that of the pillow portion itself, with a tapering design from the lower to the upper end of the pillow. These features collectively aim to improve the performance and comfort of the patient interface, ensuring a reliable delivery of respiratory gases.
