Abstract:
An elongate medical bandaging product for being dispensed in lengths suitable for a given medical use, comprising:(a) an elongate sleeve of a predetermined length formed of a moisture-impervious material and sealable to prevent entry of moisture; (b) a medical material having substantially the same predetermined length as said elongate sleeve and positioned within the sleeve in substantially moisture-free conditions and sealed therein against moisture until use, said medical material comprising: (i) a flattened tubular substrate having a pair of opposed, major surfaces defining side edges extending along the length of the elongate sleeve and characterized by being substantially free of cut fibrous ends; (ii) a reactive system impregnated into or coated onto said flattened tubular 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 (iii) a soft, flexible protective wrapping enclosing the flattened tubular substrate along its length to provide a cushioning barrier between the substrate and the skin of a patient when the material is in use.
