Abstract
A dressing for use with percutaneous tubes/drains/pins and tracheostomies that is designed to be impermeable to aid in the prevention of leakage of body secretions or fluids and to help prevent microbes from entering the body around the percutaneous device from the outside of the dressing. The dressing includes three layers or more including a layer having antimicrobial, bacteriocidal, or hemostatic agents, a cushioned absorbent layer covered by an outer see through impermeable adhesive layer.
Claims25
A unitary percutaneous tube, positive pressure dressing with components including multiple concentric overlapping layers, the dressing comprising:
- a first component having an inner treatment layer configured to cover a percutaneous tube closure site on a patient, the side of the treatment layer to be engaged with the skin of the patient non-adhesively, being coated with therapeutic agents;
- a second component having an absorbent layer sized to cover and completely surround the inner treatment layer;
- and
- a third component having an impermeable layer having an outer perimeter, the impermeable layer being sized to cover and completely surround the absorbent layer and inner treatment layer, the impermeable layer having a peripheral adhesive portion radially distal to the outer perimeter of the impermeable layer and configured to attach to the patient's skin surrounding the absorbent layer and the inner treatment layer, the impermeable layer being transparent or translucent to allow viewing of the absorbent layer and fluids from the closure site which have been absorbed up by the absorbent layer and further having phalanges integrally formed as part of the impermeable layer to secure the dressing to a percutaneous tube that resides within the percutaneous tube closure site;
- wherein the inner treatment layer, absorbent layer, and impermeable layer are generally concentric overlapping layers having increasing sizes or diameters, so that the impermeable layer covers and overlaps the absorbent layer, which absorbent covers and overlaps the inner treatment layer and each layer is formed as an integral part of the dressing to form a single unit multi-layered dressing with integral phalanges.

A unitary percutaneous tube, positive pressure dressing with multiple concentric overlapping layers comprising:
- an inner layer having therapeutic treatment material and sized to cover a percutaneous tube closure site, the side of the inner layer to be engaged with the skin of the patient being non-adhesive and therapeutic;
- an intermediate layer of absorbent material sized to cover and completely surround the inner layer;
- and
- an outer layer of impermeable material covering and completely surrounding the inner layer, the intermediate layer having an adhesive portion configured to attach to the patient's skin surrounding the percutaneous tube closure site and further having phalanges integrally formed as part of the impermeable layer to secure the dressing to a percutaneous tube that resides within the percutaneous tube closure site;
- wherein the inner layer, intermediate layer, and outer layer are generally concentric overlapping layers having increasing sizes or diameters, so that when stacked, each layer completely covers the layer below and each layer is formed as an integral part of the dressing to form a single unit multi-layered dressing with integral phalanges.

A unitary percutaneous tube, positive pressure dressing with multiple concentric overlapping layers comprising:
- an inner layer including a therapeutic treatment material configured to non-adhesively cover a patient's percutaneous tube closure site at a first location;
- an intermediate layer including an absorbent material sized to completely surround the inner layer;
- and
- outer layer including an impermeable material sized to completely surround the intermediate layer, the outer layer having an adhesive portion configured to attach to the patient's skin surrounding the percutaneous tube closure site and further having phalanges integrally formed as part of the impermeable layer to secure the dressing to a percutaneous tube that resides within the percutaneous tube closure site;
- wherein, the inner layer, the intermediate layer, and the outer layer include a keyhole sized to fit the percutaneous tube;
- wherein the inner layer, intermediate layer, and outer layer are generally concentric overlapping layers having increasing sizes or diameters, so that when stacked, each layer completely covers the layer below and each layer is formed as an integral part of the dressing to form a single unit multi-layered dressing with integral phalanges;
- and
- a second dressing having a cushioned layer configured to attach to the patient's skin at a second location spaced from the first location, the second dressing having at least one adhesive strip configured to couple with the percutaneous tube to prevent the percutaneous tube from dislodging.
