ABSTRACT:
A cover, for a flexible patient breathing mask, which is made predominantly of a soft material and has an open bottom and an internal shape corresponding to the external shape of a patient mask. The cover has a socket piece opening opposite the open bottom. The socket piece opening corresponds to the socket piece on a patient mask. Openings are formed in the side faces of the cover, which allow visual access to the patient mask. The chin and cheek sections of the cover are deformable so that the mask is capable of distorting the cheek and chin sections of the breathing mask so that the mask is tightly fitted against the anatomy of the face of the patient to alter the shape of the cover through the application of force. The side edges of the cover may include at least one fastening device for straps for holding the cover and the mask tight against a patient's face, where the fastening device(s) may be hook-shaped.
