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.

f) means for attaching said sealing strips to one or more of said first, second or third sealing sections of said peripheral sealing section, and for attaching said sealing strips and said peripheral sealing section of said mask to the facial contours and skin of the wearer to provide a customized mask for tightly sealing said mask and for preventing the leakage of gas therefrom.

2. A respiratory mask in accordance with claim 1, further including a plurality of metal strips connected to one or more of said first, second and third sealing sections of said peripheral sealing section for maintaining the desired shape and adaptability of said mask against the bridge of the nose and upper lip of the user'"'"'s face.

3. A respiratory mask in accordance with claim 1, wherein said central section of said mask has a contoured shape for receiving the wearer'"'"'s nose therein.

4. A respiratory mask in accordance with claim 1, wherein said tubular section further includes an annular central opening for alignment with and connection to said second opening of said central section.

5. A respiratory mask in accordance with claim 1, wherein said tubular section further includes a first end for connection to gas supply means and a second end having an auxiliary vent component therein, and said tubular section having a check valve mounted therein.

6. A respiratory mask in accordance with claim 1, wherein said central section of said mask further includes a pair of vent holes formed therein adjacent to said central opening.

7. A respiratory mask in accordance with claim 1, wherein said means for attaching include double-sided adhesive film, double-sided adhesive tape, pressure-sensitive adhesive, pressure-sensitive glue, pressure-sensitive gel or other adhering material.

8. A respiratory mask in accordance with claim 1, wherein said means for attaching includes a peelable protective covering for protecting the skin attaching surface of said means for attaching prior to use.

9. A respiratory mask in accordance with claim 8, wherein said peelable protective covering is made of paper, cellophane, polyvinyl chloride (PVC), aluminum foil, polyethylene (PE), Teflon, silicone tapes, gels, plastic film or composites thereof.

10. A respiratory mask in accordance with claim 1, wherein said thermoplastic material is selected from the group consisting of ethyl vinyl acetate, methyl vinyl acetate, methyl acrylate, urethanes, an acrylic or a carboxylate compound.
