摘要:
Proposed is a novel soluble trauma-healing and hemostatic cellulose fiber capable of absorbing and readily dissolving hemorrhaging trauma loci when applied thereto and of promoting the hemostatic action of blood platelets and fibrin and cell adhesion to the trauma site. The coagulation protein-containing soluble trauma-healing and hemostatic cellulose fiber is produced in that after treatment of a natural or regenerated cellulose fiber with an aqueous sodium hydroxide solution, said fiber is carboxymethylated by reaction with a monochloro acetic acid solution for a given time (hours) in such a manner that the degree of partial substitution of the glucose units constituting the cellulose molecule (etherification degree) is 0.5-less than 1.0% and that, furthermore, the coagulation proteins fibrinogen, thrombin, and coagulation factor XIII are imparted by surface application or chemical bonding.
摘要:
Novel hemostatic soluble cellulose fibers for treating wound, when applied to a bleeding wound, which absorb moisture therein and are easily dissolved to thereby assist the hemostatic effect and cell adhesion to the wound of blood platelets and fibrin contained in the blood. These hemostatic soluble cellulose fibers for treating wound are prepared by treating natural or regenerated cellulose fiber with an aqueous sodium hydroxide solution, carboxymethylating it by reacting with a monochloroacetic acid solution for a definite period of time in such a manner as to give a partial degree of substitution (degree of etherification) of hydroxyl in the glucose unit constituting the cellulose molecules of from 0.5 to less than 1.0, and applying or chemically bonding a coagulating protein fibrinogen, thrombin or blood coagulation factor XIII.
