Abstract
The present invention involves the partial carboxymethylation of cellulose to provide antithrombogenic characteristics when used as a hemo dialysis membrane. Partial carboxymethylation is obtained by reacting cellulose with an alkali chloroacetate.
Claims4
An artificial kidney machine having a hemo dialysis cellulosic membrane containing alkali carboxymethylation to the extent of about 5 - 12 percent of that alkali carboxymethylation which may be theoretically incorporated in said membrane.
A cell for subjecting blood to dialysis having a cellulosic dialysis surface containing alkali carboxymethylation to the extent of about 5-12 percent of that alkali carboxymethylation which may be theoretically incorporated into said surface.
