Abstract
A respiratory mask device includes a mask body that has a front gas inlet and a rear abutment end to contact a patient's face, left and right upper connectors disposed on left and right sides of the front gas inlet for connection with an upper head strap, left and right lower connectors respectively disposed beneath the left and right upper connectors, and left and right cantilever arms fixed at a top side of the mask body. The left and right cantilever arms extend downward and sideward from the top side and have bottom free ends carrying respective left and right upper connectors. With the cantilever arms, pulling forces can be dispersed uniformly on the mask body, and uncomfortable pressure experienced by a user may be eliminated.
