  • Patent number: 12752068
    Abstract: 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.

  • Patent number: 12752070
    Abstract: 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.

  • Patent number: 12751852
    Abstract: A nasal dilation respiratory device and system configured to be attached to a user's nasal region to achieve nasal cavity dilation. The device comprises a support member having two end portions, an intermediate portion, and at least one attachment surface, and at least one connector including a first portion and a second portion. The first portion is attached to lateral regions of the user's nose, and the second portion is detachably connected to the attachment surface. The support member applies an outward force to the nasal alar through its end portions to expand the nasal cavity. The connection mechanism may include a hook-and-loop structure, and the support member may be arcuate, arch-shaped, or linear. The device features simple structure, stable wearing, effective dilation, and strong adaptability, suitable for improving nasal airflow and relieving nasal congestion and snoring.

  • Patent number: 12740886
    Abstract: An adjustable nasal dilator designed to fit on a patient's nose and apply an outward expansion force to enhance airflow through the nasal passages. The device includes a supporting member, a fitting assembly, and an adjusting assembly. The supporting member has at least two opposing ends configured to laterally fit against both sides of the patient's nose. The fitting assembly includes first connecting portions attached to the nose and second connecting portions attached to the two ends of the supporting member, which mutual engage during use. The adjusting assembly allows the user to independently control the expansion level of the device, representing a major innovation over existing products. Through its adjusting mechanism, the adjusting assembly regulates a tensioning member to vary the angle of the left and right ends of the supporting member.

  • Patent number: 12741113
    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.
