1. A facial seal comprising:
a seal adapted to be coupled to a mask body, wherein the seal is formed from a pliable gel substance that recoils back to substantially its original shape when not stressed and has a resiliency defined as a Shore 00 durometer of less than about 10, and wherein the seal includes a first portion adapted to contact a face of a human user.
2. The facial seal of claim 1, wherein the seal comprises a peripheral wall portion having the first portion provided at a first end of the peripheral wall and a second portion provided ast an second end portion of the peripheral wall, wherein the second portin is adapted to attach to a body of a respiratory mask, and wherein the first portion is contoured.
3. The facial seal of claim 2, further comprising an attaching means for attaching the second portion to the body of the respiratory mask.
5. The facial seal of claim 1, further comprising means for strengthening the peripheral wall portion of the seal.
7. The facial seal of claim 1, wherein the resiliency of the seal is defined as a Shore 000 durometer of from about 20 to about 45.
8. The facial seal of claim 1, wherein the gel substance is a viscoelastic polyurethane polymer.
9. The facial seal of claim 1, further comprising a protective covering diposed over at least a portion of the seal.
10. The facial seal of claim 1, wherein the seal is also formed from a selectively formable substance that is adapted to be molded by a compressive force acting on the first portion from a first pattern into a second pattern and to retain the second pattern responsive to being so molded and even after the compressive force is removed.
11. The seal according to claim 10, wherein the selectively formable substance includes a combination of the gel substance and a stiffening agent.
12. The seal according to claim 11, wherein a mixture ratio of the gel substance to the stiffening agent gradually changes over a dimension of the seal.
a respiratory mask body;
a seal formed from a pliable gel substance that recoils back to substantially its original shape when not stressed and has a resiliency defined as a Shore 00 durometer of less than about 10, and wherein the seal includes a first portion adapted to contact a face of a human user, a second portion, and a wall extending between the first protion and the second portion; and
an attaching member coupled to the second portion of the seal and to the respiratory mask body to attach the seal to the respiratory mask body.
14. The mask of claim 13, wherein the attaching member is less resilient than the seal.
15. The facial seal of claim 13, further comprising means for strengthening the wall of the seal.
16. The facial seal of claim 13, wherein the seal has a generally triangular shape.
17. The facial seal of claim 13, wherein the resiliency of the seal is defined as a Shore 000 durometer of from about 20 to about 45.
18. The facial seal of claim 13, wherein the gel substance is a viscoelastic polyurethane polymer.
19. The facial seal of claim 13, further comprising a protective covering diposed over at least a portion of the seal.
20. The facial seal of claim 12, wherein the seal is also formed from a selectively formable substance that is adapted to be molded by a compressive force acting on the first portion from a first pattern into a second pattern and to retain the second pattern responsive to being so molded and even after the compressive force is removed.
21. The seal according to claim 20, wherein the selectively formable substance includes a combination of the gel substance and a stiffening agent.
22. The seal according to claim 21, wherein a mixture ratio of the gel substance to the stiffening agent gradually changes over a dimension of the seal.
