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.
Claims25
A face mask assembly, comprising:
- a frame;
- a face mask;
- an elbow;
- and
- a modular connector configured to:
- connect the frame with the face mask and to the elbow to create a pathway to transmit positive pressure air or breathable air, the connector unitarily comprising:
- a fitting to detachably connect with the frame;
- a first interface end to assemble with and connect to the face mask;
- and
- a second interface end to assemble with and connect to the elbow, and
- wherein an annular passage connects the first interface end and the second interface end to allow the positive pressure air or breathable air to pass through and enter an airway,
- wherein an axis of the connector coincides with an axis of a gas outlet at the elbow,
- wherein the connector passes through a central opening of the frame and is fixedly connected to the frame to prevent sliding or rotation of the connector relative to the frame;
- wherein the first and second interface ends are unitarily formed as the connector and a length of the connector is at or between 3 to 50 mm;
- wherein an inner diameter of the connector does not exceed 80 mm;
- and
- wherein a minimum ratio between an opening area of the second interface end and an outer surface area of the frame is 1:20.
