A comfortable, well-sealing respiratory mask with an annular comfort layer. The respiratory mask includes a rigid component, an elastic component, and an annular comfort layer. The rigid component is equipped with a gas delivery interface and an annular interface; the elastic component is connected to the rigid component and features a first accommodation area designed to house the user's mouth and nose or only the nose. On one side of the elastic component far away from the rigid component, there is at least one pressing part designed to seal at least a portion of the user's nose; the annular comfort layer has a second accommodation area that communicates with the first accommodation area, covering at least part of the pressing part and jointly forming a sealed surface with the elastic component.

A respiratory mask configured to adapt and comfortably seal according to the facial features of different users. The respiratory mask includes a support chamber, a cushioning part, and a comfort layer. The support chamber has curved sidewalls and two circular openings of varying sizes. The cushioning part includes of an elastic body and a sponge body. The fixed side of the elastic body is connected to the support chamber. The sponge body has a curved side and a connecting side that connects to the elastic body. The first side of the comfort layer is configured to make partial contact with the user's face, while the second side of the comfort layer connects to the sponge body. Both the cushioning part and the comfort layer are configured to deform, collaboratively ensuring a tight seal around the user's face.

A connector can be installed on the frame of a mask assembly used for the treatment of sleep apnea. This connector can be detachably connectable to a mask and an elbow, making it compatible with various masks and elbows. The commonality of the connector offers more choices for patients. While ensuring effective exhaust, the connector is also easy to clean, reducing the risk of patients getting infections from mold and pathogens. The connector includes a first interface end, a second interface end, and an annular channel to connect to the first interface end and the second interface end. The axis of the connector coincides with the axis of the gas outlet of the elbow. The connector passes through the central opening of the frame and is securely connected to the frame.

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.

A frame assembly for a ventilator to deliver gas includes: a frame with a first interface set on the patient's forehead, a second interface near a nasal side of the patient, and a hollow tube; wing elements, to connect to a headgear to secure the frame on the patient's face, having a first wing element and a second wing element. The hollow tube extends from the patient's first nasal side, ascends towards the first temporal region, further rises to the forehead, then extends to the second temporal region and reaches the second nasal side, to form a contour that at least partially encircles the patient's eyes and nose. A support portion, set on an inner wall of the hollow tube, is to prevent the gas delivery device from bottoming out.

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.

A nasal mask for sealing the area from the nose tip to the upper lip of the user. It includes a flexible part that curves towards one side of the user's face. The flexible part has at least one protrusion, a chamber to accommodate gas, a first opening and at least one second opening. The flexible part includes a sealing section that, during use, surrounds the area at least including the nose tip, the first nostril, and the second nostril of the user, and makes contact with the area around the nostrils. The sealing section has at least one thin region and a support region that is thicker than the thin region. The nasal mask may also include a rigid part, an exhaust port, and a spring structure.
