Claims
- 1. A casting system for application to a body portion, which comprises, before application of the casting system to said body portion, an outer layer tubular substrate carrying a water hardenable resin wherein the substrate is at least 2 mm thick and an inner layer comprising an undercast padding material comprising hydrophobic fibres or yarns.
- 2. A system as claimed in claim 1 wherein the substrate is a single layer.
- 3. A system as claimed in claim 1 wherein the substrate is a knitted substrate.
- 4. A system as claimed in claim 1 in which the resin carrying substrates is elastically extensible.
- 5. A system as claimed in claim 4 having an elasticity sufficient for it to recover to 60% of the width when stretched by 100% in the width direction.
- 6. A system as claimed in claim 4 in which the tubular material is rendered elastically extensible by means of an elastic yarn or thread.
- 7. A system as claimed in claim 1 wherein the tubular substrate comprises an elastic component.
- 8. A system as claimed in claim 1 wherein the tubular substrate comprises differently coloured materials.
- 9. A system as claimed in claim 8 wherein the substrate comprises more than one differently coloured yarns knitted into a pattern.
- 10. A system as claimed in claim 1 wherein the resin is a polyurethane prepolymer.
- 11. A system as claimed in claim 1 wherein resin is present in an amount of at least 50 gm per square meter of substrate.
- 12. A system as claimed in claim 1 wherein the resin carrying tubular substrate is provided with apertures.
- 13. A system as claimed in claim 12 wherein the substrate is a knitted substrate and the apertures are holes included within the knitting pattern.
- 14. A system as claimed in claim 12 wherein the apertures are from 1 to 100 mm.sup.2 in area.
- 15. A system according to claim 1 wherein the inner layer is in the form of a tube.
- 16. A system as claimed in claim 1 in which the padding material comprises a lofted non-woven fabric.
- 17. A system as claimed in claim 16 in which lofted non-woven fabric has a thickness of 3 to 8 mm.
- 18. A system as claimed in claim 16 in which the lofted non-woven fabric is attached to an inner support layer of tubular elastic extensible material.
- 19. A bandage system as claimed in claim 18 in which the non-woven fabric and the inner support layer are bonded together.
- 20. A system as claimed in claim 1 in which walls of the inner layer of the tube comprises non-elastic material compressed into folds to form circumferential corrugations whereby the tube is adapted to be radially extensible.
- 21. A system as claimed in claims 20 wherein the inner support layer comprises a knitted fabric.
- 22. A system as claimed in claim 1 wherein the inner and outer layers are bonded together.
- 23. A system as claimed in claim 22 wherein the inner and outer layers are adhesively bonded together.
- 24. A system as claimed in claim 22 wherein the inner and outer layers are stitched together.
- 25. A system as claimed in claim 1 further comprising a resin-impermeable water-soluble layer intermediate the inner and outer layers.
- 26. A system as claimed in claim 1 within a sealed pouch.
- 27. A system as claimed in any one of claims 1 to 26 wherein the tubular substrate is rolled up into a torus.
- 28. A system as claimed in claim 26 within a water and moisture-proof pack.
- 29. In combination a bandage system of claim 1 and an applicator therefor.
- 30. An orthopaedic cast formed from the casting system claimed in claim 1.
