Abstract: Biological fluid filtration methods are provided for the treatment of gas within a biological fluid filtration system. A quantity of biological fluid is flowed under the force of gravity through a leukocyte removal filter and into a post-filter container. The post-filter container has a maximum vented volume that is approximately the same as the quantity of biological fluid flowed through the filter and into the post-filter container. At least a substantial portion of the gas in the post-filter container is vented therefrom without separately restricting expansion of the post-filter container and without manually manipulating the post-filter container to expel gas.

Abstract: Containers and components thereof for use in the medical industry and methods to manufacture the same are described. An example tab for use with a medical container includes opposing sheets sealed to define an open ended chamber into which a port is to be at least partially positioned. The port is to enable access to the medical container. The tab includes a tear seal defined by each of the opposing sheets and a first guide positioned on a first side of each of the tear seals. The tab includes a second guide positioned on a second side of each of the tear seals, wherein the first and second guides are to enable a tear to propagate substantially between the guides and adjacent the tear seals.

Abstract: Cart assemblies for use with blood filtration are described. An example cart assembly for use with blood filtration includes a base including a recessed portion to receive one or more containers defining compartments each to receive a container of a fluid transfer system. Additionally, the base includes a plurality of transport members coupled to respective portions of the base. A plane on which a surface of the recessed portion lies is below a portion of each of the plurality of transport members. Additionally, the cart assembly includes a hanger assembly comprising a plurality of suspension members from which another container of the fluid transfer system is to be suspended and a pole to couple the base to the hanger assembly.

Abstract: Biological fluid filtration systems and methods are provided for the treatment of air within the system. A filtration system includes a pre-filter container joined to an expandable post-filter container by a filter line having a filter. The post-filter container has a relatively smaller maximum volume, such that it limits the amount of gas in the post-filter container during and after filtration of a biological fluid, thereby improving removal of air from the post-filter container.

Abstract: Biological fluid filtration systems and methods are provided for the treatment of air within the system. A filtration system includes a pre-filter container joined to an expandable post-filter container by a filter line having a filter. The post-filter container includes a volume restriction that limits its expansion upon receipt of a filtered fluid. In use, a fluid is transferred from the pre-filter container, through the filter line and the filter, to the post-filter container. The volume restriction limits the expansion of the post-filter container during filtration, which increases the pressure within the post-filter container, thereby improving removal of air from the post-filter container.
