Abstract

A novel occlusive dressing which allows the escape of fluid and air in cases of penetrating thoracic trauma. The dressing comprises a one-way valve that lies flat on the body of the patient during use such that the fluid from the wound is able to drain away without air from the surrounding environment penetrating the wound.

Claims

1. A dressing comprising

a bandage section having a perimeter sufficient to occlude a wound, and

a valve section that allows the escape of fluid, wherein the valve section lies substantially on the same plane as the bandage section.

2. A dressing, as in claim 1, wherein the bandage section comprises a transparent area.

3. A dressing, as in claim 1, wherein an outer edge of the bandage section is provided with adhesive.

4. A dressing, as in claim 3, wherein the adhesive is covered with a removable protective outer film prior to use.

5. A dressing, as in claim 1, wherein the valve section comprises a one-way valve.

6. A dressing, as in claim 5, wherein the one-way valve comprises a flutter valve.

7. A dressing, as in claim 6, wherein the flutter valve comprises one leaflet.

8. A dressing, as in claim 6, wherein the flutter valve comprises two leaflets.

9. A dressing, as in claim 5, wherein the one-way valve is housed in a substantially rigid casing.

10. A dressing, as in claim 1, wherein the bandage section is substantially elliptical or circular in shape.

11. A dressing, as in claim 1, wherein the bandage section is provided with an extending tag section, wherein the extending tag section facilitates easy gripping of the dressing.

12. A dressing, as in claim 1, wherein the valve section can be provided with a collection bag.

13. A dressing, as in claim 1, wherein the dressing comprises a waterproof material.

14. A dressing, as in claim 1, wherein the dressing comprises a non-allergenic material(s).

15. A dressing, as in claim 1, wherein the dressing comprises a plastic material.

16. A dressing, as in claim 1, wherein the dressing comprises a latex.

17. A dressing, as in claim 1, wherein the valve section is provided with an irrigation flushing system.

18. A dressing, as in claim 17, wherein the irrigation flushing system comprises an aperture in the casing of the valve section through which fluid can be inserted.

19. A dressing, as in claim 17, wherein the irrigation flushing system comprises a tube and a valve.

20. A dressing, as in claim 19, wherein the tube is provided with perforations.

21. A dressing, as in claim 1, wherein the bandage section comprises one or more membrane layers.

22. A dressing, as in claim 21, wherein the bandage section comprises two or more membrane layers, and wherein, in use, air or fluid is provided between the membrane layers, such that tension is applied to a wound.
