Abstract
A medical dressing to treat sucking chest wound, and methods of forming the medical dressing. The methods include the steps of overlaying a cover layer on an intermediate layer and the intermediate layer on a base layer such that openings in the intermediate and base layers are aligned and the cover layer overlays the openings; fusing together the cover layer, the intermediate layer and the base layer by applying an annular welding tool face to at least one of the cover layer and base layer and applying welding energy to the template; and applying an adhesive layer on a side the base layer opposite to the intermediate layer, wherein the adhesive layer extends entirely around the opening.
Claims21
A method of forming a medical dressing comprising the steps of:
- placing a base layer on a flat substrate, the base layer having a first opening;
- laying an intermediate layer on the base layer, the intermediate layer having a second opening;
- laying a cover layer on the intermediate layer;
- aligning the first and second openings of the base and intermediate layers;
- centering the cover layer on the first and second openings;
- and
- applying energy to the cover layer, intermediate layer and base layer, whereby the energy fuses the cover layer, intermediate layer and base layer together;
- wherein the energy applying step includes fusing the cover layer, intermediate layer and base layer around the first and second openings except at slots extending beyond an outer edge of the cover layer and ending before an outer edge of the intermediate layer.
