Abstract

Embodiments of apparatuses and methods for preventing facial wounds caused by an applied ventilation mask are provided. For example, the apparatus includes a cushion formed in an inverted “V” shape, wherein the cushion comprises a superior portion and two inferior portions, wherein the superior portion corresponds to the vertex of the inverted “V” shape, wherein the superior portion is configured to cushion the nose of a human, and wherein the two inferior portions are configured to cushion the cheekbones of a human.

Claims

1. An apparatus for preventing facial wounds caused by an applied ventilation mask, comprising:

a ventilation mask for providing breathable gases to a patient,

a single piece, same-molded, cushion formed in an inverted “

V”

shape in which the lower portion of the inverted “

V”

is open, and including a plurality of ribs for cushioning, relieving pressure, and absorbing shock applied to said cushion by said ventilation mask,

wherein the cushion comprises a superior portion and two inferior portions,

wherein the superior portion corresponds to the vertex of the inverted “

V”

shape and has increased thickness to cushion the bridge of a wearer'"'"'s nose,

wherein the superior portion is sized and shaped to contact the nose of a human while the two inferior portions are sized and shaped to respectively contact the cheekbones of the human such that the superior portion cushions the nose from the ventilation mask and the two inferior portions cushion the respective cheekbones from the ventilation mask.

2. The apparatus of claim 1, wherein the cushion is sized and shaped to be thicker where the cushion contacts a pressure point of the face of the human.

3. The apparatus of claim 1, wherein the superior portion is thicker than at least one of the two inferior portions.

4. The apparatus of claim 1, wherein the cushion includes a cushioning material selected from the group consisting of:

silicone and a hydrocolloid material.

5. The apparatus of claim 1, wherein the cushioning material is a flexible material.

6. The apparatus of claim 1, wherein the cushion includes a cushioning material including an injectable gel selected from the group consisting of:

a silicone elastomer, medical grade gel, and foam rubber.

7. The apparatus of claim 1, wherein the cushion is operative to redistribute pressure applied by a ventilation mask away from a pressure point.

8. The apparatus of claim 1, wherein the cushion is dimensioned to accommodate the ventilation mask.

9. The apparatus of claim 1, further comprising a medication coating applied to a surface of the cushion.

10. The apparatus of claim 9, wherein the medication coating is selected from the group consisting of:

a vasodilator and an antibiotic ointment.

11. The apparatus of claim 1, wherein the cushion includes a perforation.

12. The apparatus of claim 1, wherein the cushion includes a plurality of pores.

13. The apparatus of claim 1, wherein the cushion further defines openings adjacent to the ribs.

14. The apparatus of claim 13 in which said cushion has a thickness and said openings extend through a portion of said thickness.

15. The apparatus of claim 13 in which said cushion has a thickness and said openings extend through said thickness.

16. The apparatus of claim 1, wherein the superior portion includes a lip protruding from the superior portion.

17. The apparatus of claim 1, further including an attachment means for attaching the cushion to the ventilation mask.
