Patent

CA 2235218

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.

L'invention concerne un sac filtrant (200) et une cartouche de raccord, servant à recueillir des liquides physiologiques. Le sac (200) comprend un filtre interne (206) et deux joints d'étanchéité (218, 220) sur le périmètre. Les deux feuilles externes (202, 204) du sac et le filtre sont liées par un joint interne (218) et les deux feuilles externes (202, 204) seules sont liées par un joint externe (220) qui fontionne comme un joint de sécurité. Le sac comporte un élément de vérification qui coopère avec un raccord de vérification, ce qui permet d'assurer que le sac est raccordé correctement à la ligne d'alimentation en liquide, avant que la pompe à liquide ne soit actionnée.
