Abstract
A patient interface is described which is reduces the pressure of the mask on the users face. The patient interface has a sealing interface having an inner sealing member and an outer sealing member. The inner and outer sealing members are adapted to seal around the facial contours of a user providing a sealed fluid communication to the user's respiratory tract. The inner and outer sealing members are at least continuously in contact with each other around the portions where the sealing interface contacts the user's facial contours. The inner sealing member may be provided with cut outs to provide additional flexibility to particular areas, such as the nasal bridge, upper lip or cheek regions and may be provided with a contoured edge to better fit the facial contours of a user.
