ABSTRACT:
A lyophilized foam sponge product having medically useful hemostatic and adhesive properties formed from the hydrocolloids, gelatin, pectin, and sodium carboxymethylcellulose and having a density of from about 0.01 to about 0.10 grams/cc. The gelatin is present at from about 20% to about 80% by weight of the final product and the pectin and sodium carboxymethylcellulose are each present at from about 10% to about 50% by weight of the final product. The product is prepared by forming an aqueous colloidal dispersion of hydrocolloids, aerating or foaming, freezing, and lyophilizing.
