Nasal interface for separate inspiratory and expiratory gas delivery
The patent US12070553B2 describes a patient interface designed for the delivery of inspiratory gases and the collection of expiratory gases through a pair of nasal interfacing components. Each component is engineered to create a substantial seal with the user's nares, ensuring effective gas exchange. The interface includes a valve that selectively controls gas flow, allowing for different operational modes. In the first mode, inspiratory gases are delivered through one nasal component while expiratory gases are collected through the other. The second mode reverses this flow. Additionally, a further mode enables simultaneous delivery of inspiratory gases to both components, with the valve facilitating transitions between these modes.
The design incorporates a partition between the nasal components, which can provide mechanical fluid disconnection or adjustable connection between their respective gas flow paths. The valve is strategically located in a bridge region connecting the nasal components, allowing for fluid communication adjustments. The interface also features conduits for connecting to gas sources and downstream devices, enabling the management of inspiratory and expiratory lines. Sensors are included to monitor gas flow and pressure, providing indications of potential leaks or therapy interruptions. Furthermore, a retention system is integrated to secure the interface on the user's face, allowing for easy adjustment and repositioning. This innovative design aims to enhance the efficiency and comfort of respiratory therapy for users.
