  • Publication number: 20250235655
    Abstract: A headgear for use in the Positive Airway Pressure field includes an inner layer, a bonding layer, a padding layer, film layers, and an adhesive. The inner layer is configured to be at least partially in contact with a patient's skin during use, while the bonding layer is configured to adhere an outer side of the headgear, which comes into contact with the air, to a fixed part by folding the headgear, thereby tightening or loosening the headgear. The padding layer, placed between the inner layer and the bonding layer, increases thickness. The film layers are provided between the inner layer and the padding layer, as well as between the padding layer and the bonding layer. The adhesive is configured to bond the layers together. The headgear has at least three layers and is made of at least two types of textile materials.

  • Publication number: 20250195811
    Abstract: A patient interface assembly with optimized connection methods and improved air-tightness. The patient interface assembly forms a complete channel to deliver positive pressure air when connected with an air supply tube and a ventilator. The patient interface assembly includes a patient interface pad, a frame, an elbow assembly, and a quick-release connector. The patient interface pad is fixedly connected to one end of the elbow assembly. The frame is positioned between the elbow assembly and the patient interface pad. The other end of the elbow assembly is connected to the quick-release connector. By reducing the connection steps between parts, the air-tightness of the patient interface assembly is enhanced, and the patient interface assembly is adaptable to various types of frames.

  • Publication number: 20250195817
    Abstract: A ventilation elbow assembly, which is directly connectable to a face mask. The elbow assembly includes an elbow, connector, ventilation port, noise reduction device, and quick-release connector. The elbow has a first interface, second interface, and annular channel. At the first interface, there is at least one stepped portion, which is configured to connect to the face mask and seal pressurized gas. A baffle is provided at the first interface, limiting frame movement relative to the face mask and elbow. The assembly also includes an anti-asphyxiation valve to prevent the patient from asphyxiation without continuous positive pressure in the elbow. With a connector, the elbow can first connect to the connector before the face mask, expanding the range of movement of the elbow assembly relative to the face mask. This is configured to increase the range of movement of the elbow assembly relative to the face mask.

  • Patent number: 12311106
    Abstract: A breathing mask includes a rigid member, an elastic member, and a foam member. The rigid member has an interface on the side away from the user's face for accessing the breathing gas of the continuous positive airway pressure device, and a flared joint on the side adjacent to the user's face. The elastic member is in communication with the inner cavity of the rigid member and is fixedly connected to the flared joint. The side of the elastic piece adjacent to the user's face at least partially abuts the user's nasal bridge area to form an elastic body part, and a support part connected to the elastic body part is provided on the side of the elastic member adjacent to the user's face. The foam member is fixed to the support part and, together with the elastic member, forms a sealing surface for fitting the user's face.

  • Patent number: 12263302
    Abstract: A heatable air delivery tube that maintains the temperature within the tube includes a patient interface end, an airflow generator end, and a heated spiral tube with metal wires that connects the two ends. The patient interface end includes a notch that allows for deformation to better achieve a seal when connected to other tubular connectors. The airflow generator end has a deformable connecting clamp, which allows for self-deformation to secure a snap-fit connection with the airflow generator. The inner diameters of the connectors of both the patient interface end and the airflow generator end are no larger than the tubular connectors they connect to, to ensure a better seal.
