Wound dressing retainer and fastening device
View Patent ↗An external wound dressing retainer includes a frame having an opening substantially surrounded by the frame, wherein the opening is bounded by a plurality of edges, wherein the frame includes a first side and a second side including an adhesive for adherence to skin of a patient; a flap having a plurality of edges, wherein the dimensions of the flap substantially correspond to the dimensions of the opening, and the flap is attached to the frame via a corresponding edge of the flap and the frame; and a sealing mechanism for releasably engaging non-attached edges of the flap to corresponding non-attached edges of the frame. The sealing mechanism is a zipper arrangement that includes complementary interlocking first and second grooves situated on the non-attached edges of the flap and the frame, respectively, further comprising a sliding element adapted to sealably join the first groove to the second groove.
1. An external wound dressing retainer comprising:
a flexible frame having an opening substantially surrounded by the frame, wherein the opening is bounded by a plurality of edges, wherein the frame includes a first side and a second side including an adhesive for adherence of the frame to skin of a patient;
a flexible flap having a plurality of edges, wherein the dimensions of the flap substantially correspond to the dimensions of the opening, and the flap is attached to the frame via a corresponding edge of the flap and the frame; and
a sealing mechanism for releasably engaging non-attached edges of the flap to corresponding non-attached edges of the frame, wherein the sealing mechanism includes a zipper arrangement having complementary interlocking first and second grooves situated on the non-attached edges of the flap and the frame, respectively, further including a sliding element adapted to sealably join the first groove to the second groove, wherein the sealing mechanism provides a liquid-proof seal between the edges of the flaps and the edges of the frame.
2. The external wound dressing retainer of claim 1 , wherein the sliding element further comprises one of a ridged surface and a tapered surface.
3. The external wound dressing retainer of claim 1 , further comprising a removable backing affixed to the second side of the frame.
4. The external wound dressing retainer of claim 1 , wherein the depth of the frame is sized to accommodate a dressing within the opening of the frame.
5. The external wound dressing retainer of claim 1 , wherein the flap is selectively movable from a closed position covering the opening to an open position so that the opening is uncovered.
6. The external wound dressing retainer of claim 1 , wherein the adhesive provides a water-resistant seal between the frame and the skin of the patient.
7. The external wound dressing retainer of claim 1 , wherein the flap is constructed of non-absorbent material.
8. The external wound dressing retainer of claim 1 , wherein the opening is one of 2″×2″; 4Δ×4″; 4″×6″; 5″×9″; and 8″×10″ in size.
9. The external wound dressing retainer of claim 1 , wherein the frame is substantially rectilinear.
10. The external wound dressing retainer of claim 9 , wherein the distance from an inner portion of the frame defined by any of the edges to an outer periphery of the frame is at least one inch.
11. The external wound dressing retainer of claim 1 , wherein the frame is constructed of semi-rigid foam material.
