Abstract
A strapless respiratory facial mask for attachment to the wearer's face including a mask having a central section and three edges forming a generally triangular configuration for covering and surrounding the nose of the wearer; wherein the first and second edges of the mask extend along the opposite sides of the nose of the wearer, and the third edge extends across the upper lip area of the wearer. The central section of the mask is formed of a thermoplastic material and has a first central opening formed therein for making an external connection to the mask, and having a second central opening below the first central opening and an external tubular section connected to the second central opening for making a connection to a gas supply. The mask further includes an elastic and moldable cushioning material connected to the first, second and third edges of the mask to form a peripheral sealing section for engaging the facial contours and skin of the wearer's face. The peripheral sealing section includes first, second and third sealing section edges. In addition, the mask also includes a plurality of sealing strips formed of the cushioning material for attachment to one or more of the first, second or third sealing section edges for providing an increased sealing area for the mask.
