STERILE FLUID FILTRATION CARTRIDGE AND METHOD FOR USING SAME

摘要

A filtration assembly is presented which removes bacteria and endotoxin from a solution so that a sterile fluid is produced. The sterile fluid is suitable for direct on-line infusion to a patient from a device, such as a dialysis machine. The filtration assembly is constructed so that two separate filtration compartments exist, resulting in redundant filtration of the fluid prior to infusion. Each compartment holds a filter which preferably consists of a longitudinal bundle of semipermeable hollow fibers. The filter is sized so that it creates a separate area within the compartment for filtrate and infusate flow. This redundant filtration produces a lower risk of creating a pyrogenic or septic condition in the patient due to filter failure.
