CALCIUM-MODIFIED OXIDIZED CELLULOSE HEMOSTAT

摘要

A CALSIUM-MODIFIED OXIDIZED CELLULOSE HEMOSTAT PROVIDES FASTER HEMOSTASIS THAN DOES EITHER UNMODIFIED OR SODIUM-OR POTASSIUM-MODIFIED OXIDIZED CELLULOSE. THE PERCENTAGE BY WEIGHT OF CALSIUM IN THE MODIFIED OXIDIZED CELLULOSE MUST BE IN A RANGE BETYWEEN ABOUT 0.5 AND ABOUT 4, IN ORDER TO ENCHANCE HEMOSTASIS, WHILE NOT INTERFERING EXESSIVELY WITH BIOABSORBABILITY. IN A SECOND EMBODIMENT, AN OXIDIZED CELLULOSE HEMOSTAT IS MODIFIED WITH BOTH CALSIUM AND EITHER SODIUM OR POTASSIUM. THE SECOND EMBODIMENT MAY BE USED TO DELIVER ACID-SENSITIVE MATERIALS.
