Abstract
A cast tape or medical bandaging product formed from a resin-coated or impregnated fabric material that includes a knitted substrate having a combination of non-fiberglass high and low tenacity yarns such as polypropylene, polyester and elastomer. The polypropylene and polyester yarns have a high number of filaments, typically 48 to 90 filaments. This significantly improves the surface area of the fabric, that helps help to hold the curable resin onto the fabric and avoids pooling. This in turn improves lamination layer-to-layer and gives the substrate high strength.
Claims28
A medical bandaging product, comprising:
- (a) a sleeve of a predetermined length formed of a moisture-impervious material and sealable to prevent entry of moisture;
- (b) a medical material positioned within the sleeve in substantially moisture-free conditions and sealed therein against moisture until use, said medical material comprising:
- (i) a substrate having a pair of opposed, major surfaces, said substrate being constructed of an elastomeric yarn to provide the substrate with a predetermined extensibility;
- and
- (ii) a reactive system impregnated into or coated onto said substrate, said system remaining stable when maintained in substantially moisture-free conditions and hardening upon exposure to sufficient moisture to form a rigid, self supporting structure.
An elongate medical bandage, comprising:
- (a) an elongate medical material adapted for being dispensed in lengths suitable for a given medical use and for being maintained in substantially moisture-free conditions until use, said medical bandage comprising:
- (i) a knitted substrate knitted of elastomeric yarns and defining a pair of opposed major surfaces;
- and
- (ii) a reactive system impregnated into or coated onto said substrate, said system remaining stable when maintained in substantially moisture-free conditions and hardening upon exposure to sufficient moisture to form a rigid, self supporting structure.
An elongate medical bandaging product for being dispensed in lengths suitable for a given medical use, comprising:
- (a) an outer container formed of a moisture-impervious material and sealable to prevent entry of moisture, the container comprising an elongate product-dispensing sleeve having a moisture-proof sealable opening on one end and an enlarged product storage package communicating with the dispensing sleeve;
- (b) an elongate medical material positioned in the container in substantially moisture-free conditions and sealed therein against moisture until use, said medical material comprising:
- (i) a knitted substrate having a pair of opposed, major surfaces.
- (ii) a reactive system impregnated into or coated onto said substrate, said system remaining stable when maintained in substantially moisture-free conditions and hardening upon exposure to sufficient moisture to form a rigid, self supporting structure;
- and
- (c) closure means for resealing the dispensing sleeve against entry of moisture after a predetermined length of the medical material has been dispensed for use to prevent hardening of the substrate remaining in the product container.
