  • Patent number: 5601730
    Abstract: Methods and apparatuses for removing unwanted fluid such as gas from a processed blood product are disclosed. Methods include the steps of passing a blood product from a closed first container through a functional biomedical device to produce a processed blood product, flowing the processed blood product and an unwanted fluid from the functional biomedical device to a second container through a conduit, separating the unwanted fluid from the processed blood product in the second container, preventing the flow of the unwanted fluid from the second container through the passage to the functional biomedical device by using a clamp and passing the unwanted fluid from the second container to the first container through an outlet providing fluid communication between the second container and the first container. The outlet includes a barrier medium which allows the passage therethrough of the unwanted fluid but prevents the passage therethrough of the processed blood product.
