Wound barrier pad
View Patent ↗A wound barrier pad is provided having a housing with a housing opening. The housing has a truncated conical shape. A base plate with an opening is disposed in the housing, and the housing is filled with a fluid or padding. The wound barrier pad may also be embodied to have a cylindrical shape, a rectangular shape or other shape. The wound barrier pad may be incorporated into a garment. In another embodiment the wound barrier pad includes a ring and an adhesive such that the wound barrier pad may be directly adhered to the patient, thus eliminating the need for the garment. In another embodiment there is a wound barrier device having a pad assembly and an anti-shear member. The anti-shear member reduces frictional forces on the skin of a patient.
1. A wound barrier device comprising:
an anti-shear pad having a pad assembly, wherein the pad assembly includes:
an outer layer having opposed first and second outer layer surfaces;
a center member having opposed first and second center member surfaces and an internal surrounding surface that defines a center member opening in the center member;
a cap having opposed first and second cap surfaces;
a first adhesive;
wherein the cap is adhered to the second outer layer surface of the outer layer with the first adhesive, and the second outer layer surface is adhered to the first center member surface with the first adhesive such that the cap is held between the outer layer and center member and the cap is positioned such that the center member opening leads to the cap;
an anti-shear member and a second adhesive and wherein the second adhesive joins the second center member surface to the anti-shear member; and,
wherein the anti-shear member is a flexible bladder filled with a fluid and defines a leak-proof central bladder opening that is axially aligned with the center member opening.
2. The wound barrier device according to claim 1 wherein the outer layer and the center member are made of foam and impregnated with silver.
3. The wound barrier device according to claim 1 wherein the cap is made of a resilient material and has a relaxed cap position and a flexed cap position.
4. The wound barrier device according to claim 1 wherein the outer layer, the cap, and the center member are together movable from an anti-shear pad un-flexed position to an anti-shear pad flexed position, and when in the anti-shear pad flexed position the second outer layer surface, the second cap surface, and the second center member surface are convex.
