ABSTRACT:
A face mask for the delivery of a gas to a patient includes a body portion forming an open sided chamber having a peripheral edge for contacting the face of the patient. The body portion has an integrally formed nose portion and chin portion and increases in width from the nose portion toward the chin portion giving the body portion generally triangular shape. A nose portion has a reduced dimension such that a contour of the nose portion conforms to the contour of the nose of the patient forming a sealing fit therebetween. The nose portion has an upper end terminating in all apex extending toward the bridge of the nose and is configured to contact the nose at a point substantially below the bridge of the nose so as to eliminate interference between the nose portion and the eyes of the patient. An elastic strap is secured proximal the peripheral edge of body portion to retain the face mask against the face of the patient. The elastic strap is affixed along the upper end of the nose portion proximal the apex and meets the face mask at an angle such that the upward urging of the face mask is substantially eliminated. A chin portion is formed proximal the lower end of the nose portion and includes a forward peripheral wall depending from a horizontal shelf of the nose portion. The peripheral wall is configured to contact a forward portion of the chin of the patient. The chin portion also includes a skirt formed about the forward peripheral wall that depends inwardly toward the patient and is configured to receive the chin of the patient.
