Medical material employing carboxymethyl cellulose

摘要

The purpose of the present invention is to provide a medical material which, while retaining high liquid absorbency and styptic properties through gelation of CMC, can maintain shape stability even after absorbing a liquid; which has excellent conformance to the skin; and through which the body surface to which it is to be applied is visible. This medical material is a structure comprising regenerated cellulose fibers including carboxymethyl cellulose fibers in which the degree of substitution of the hydroxyl groups in the glucose units making up the cellulose molecule is at least 0.1 but less than 0.5, wherein the medical material is characterized in that the structure has the form of a woven and/or nonwoven fabric, and when the structure is impregnated with physiological saline, the range of the 10% modulus in both the longitudinal direction and the lateral direction of the structure is 0.2 N/50 mm-5.0 N/50 nm, inclusive.
