Abstract
A device and method for injecting a sterile pyrogen free fluid uses a main filter having first and second compartments separated by a porous membrane. The first compartment has an inlet connected to a source of fluid to be filtered, and the second compartment has an outlet connected to an injection line. A pump is provided for circulating the fluid through the main filter and into the injection line. A secondary filter is provided downstream of the main filter and, in combination with pressure sensors, is used to determine if a rupture exists in the main filter.
