| 摘要 |
A normally hydrophobic, open-celled polyurethane foam for use on the surface of a disposable surgical drape is treated with the reaction product of a mineral acid and a fatty acid tertiary amine, wherein the amine is partially neutralized to a fatty acid tertiary ammonium salt which renders the foam material antistatic, while providing increased rates of fluid absorption and reduced tendency for lathering when the foam material is rubbed with water present on the foam material. An improved disposable surgical drape comprises an outer layer of the treated foam bonded to a fluid-impervious plastic layer attached to a fibrous base sheet.
