Waterproof cast liner system and method of use

A waterproof cast liner system comprising:

• a) an inverted waterproof cast sleeve comprising:
• i) an insertion end having an insertion end opening;
• ii) an extended end having an extended end opening;
• iii) a sleeve conduit extending from the insertion end opening to the extended end opening;
• said sleeve conduit having an inside surface and an outside surface;
• wherein the inverted waterproof cast sleeve is configured for placement over a limb with the insertion end extending around said limb and the extended end configured inverted back over the outside surface of the sleeve conduit to form a waterproof cast liner comprising:
• an outer layer of the inverted sleeve;
• an inner layer of the inverted sleeve;
• and
• an inverted end;
• wherein the outer layer and inner layer are configured to overlap each other to form said waterproof cast liner;
• b) a seal between the inner layer and outer layer to produce a waterproof enclosure between the inner layer and outer layer;
• c) a padding material configured within the waterproof enclosure between the outer layer and inner layer;
• d) a rigid layer configured over the outer layer to produce a waterproof cast.

A method of making a waterproof cast, said method comprising:

• a) providing a waterproof cast liner comprising:
• i) an inverted waterproof cast sleeve comprising:
• an insertion end having an insertion end opening;
• an extended end having an extended end opening;
• a sleeve conduit extending from the insertion end opening to the extended end opening;
• said sleeve conduit having an inside surface and an outside surface;
• b) providing a padding material;
• c) providing a rigid material;
• d) extending the insertion end of the waterproof cast sleeve over a limb to produce a covered limb;
• e) applying said padding material over said covered limb;
• f) inverting the waterproof cast sleeve by configuring the extended end back over the covered limb to produce an inverted sleeve comprising:
• i) an outer layer of the inverted sleeve;
• ii) an inner layer of the inverted sleeve;
• and
• iii) an inverted end;
• wherein the padding material is configured between the outer layer and inner layer of the inverted sleeve;
• g) coupling the inner layer and outer layer of the inverted sleeve together proximal to the insertion end to produce a seal between the inner layer and outer layer and a waterproof enclosure between the inner layer and outer layer of the inverted sleeve;
• wherein the padding is configured within said waterproof enclosure;
• h) applying said rigid material over the inverted sleeve to produce a waterproof cast.
