| titleOfInvention | A method of manufacturing a supporting dressing for broken bones and other injured parts |
| abstract | A material suitable for making a rigid supporting dressing is made by immersing a loosely woven textile fabric in a mixture of an aqueous emulsion of a hard plastic material and a binding agent which is dissolved or dispersed in water and is active as a binding agent when dry and which is also insoluble in a solvent for the hard plastic material, and the fabric is then dried. Hard plastic materials are defined as synthetic resins having a brittle point above 20 DEG C. such as polymethylmethacrylate, polyisobutylmethacrylate and polystyrene. Binders specified include polyvinyl alcohol, casein, water-soluble cellulose derivatives (e.g. sodium carboxymethylcellulose), water-soluble acryl products (e.g. polyacrylamide and salts of polymethacrylic acid), polyvinylpyrrolidone and water glass. The dried fabric may be dipped into a solvent for the hard plastic material and applied to an injured limb in six or eight windings. Suitable solvents include ketones (acetone, methylethylketone), esters (ethyl and methyl acetates), acetals dimethyl formal, diethylformal and dimethylacetal) and chlorinated hydrocarbons (methylene chloride, ethyl chloride, isopropyl chloride, butyl chloride and dichloroethylene) and other low-boiling non-toxic compounds. The rate of evaporation and/or the flammability of the solvent may be regulated by addition of low-boiling esters, paraffin hydrocarbons and fluorochloro-hydrocarbons. In an example a loosely-woven spun rayon fabric is dipped into a mixture of an emulsion of polymethylmethacrylate and polyvinyl alcohol. The treated dried web is then immersed in acetone, excess solvent removed and the web applied to an injured limb to form a rigid dressing. Specification 780,795 is referred to. |
