Connecting piece for breathing machine frame

Abstract

The utility model relates to the technical field of respiratory therapy, and particularly discloses a connecting piece which is installed on a frame in a mask combination for treating sleep breathing disorder and detachably connected with a mask and an elbow, can be matched with different masks and elbows, is good in generality, can provide more choices for patients, and is easy to clean and convenient to use while guaranteeing the exhaust effect. The risk that a patient is infected with molds, pathogens and the like can be reduced. The connecting piece comprises a first interface end used for being assembled and communicated with the mask, a second interface end used for being assembled and communicated with the elbow, and an annular channel communicating the first interface end and the second interface end and allowing pressurized air to pass through to enter an airway of a patient. The axis of the connecting piece coincides with the axis of the gas outlet of the elbow, and the connecting piece penetrates through the central opening of the frame and is fixedly connected with the frame; the wall thickness of at least part of the connecting piece is smaller than 3 mm, the length of the connecting piece is 3-50 mm, and the inner diameter of the connecting piece is not larger than 80 mm.
