Abstract
A filter bag (200) and connector cartridge are used for collection of physiological fluids. The bag (200) includes an internal filter (206) and two seals (218, 220) on the perimeter. An inner seal (218) bonds the outer sheets (202, 204) of the bag and the filter, while the outer seal (220) bonds only the two outer sheets (202, 204) and acts as a safety seal. The bag includes a verification element that cooperates with a verification connector to ensure that the bag is properly attached to the fluid supply line before a fluid pump is enabled.
