    摘要: Method for inactivating non-enveloped viruses using a viricide-potentiating agent. In a preferred embodiment, the method may be used to inactivate non-enveloped viruses present within a sample of whole blood or a blood product and comprises (a) adding to the blood sample a photoactivatable viricide, such as a psoralen, hypericin, methylene blue, toluidine blue or the like, which, when activated, is effective in inactivating enveloped viruses; (b) adding to the blood sample a viricide-potentiating chemical agent that increases the sensitivity of non-enveloped viruses to the activated viricide; and (c) activating the photoactivatable viricide. Preferably, the viricide-potentiating chemical agent includes a first moiety which possesses an affinity for a component of the non-enveloped virus and a second moiety which includes a lipid tail, the first and second moieties being structurally interrelated so that, when the first moiety becomes associated with a component of the non-enveloped virus, the second moiety penetrates or at least partially surrounds the viral capsid of the non-enveloped virus. Examples of the chemical agent include cationic lipopolyamines, such as dioctadecylamidoglycylspermine.

    摘要: A filtration system for the filtration of a biological fluid includes a filtration device (100) interposed between a fluid supply source (110) and a collection container (120). The filtration device (100) includes a filtration assembly disposed within a housing (210). The housing (210) has an inlet (212) for receiving unfiltered fluid from the supply source (110) and an outlet (214) for exiting filtered fluid to the collection container (120). The filtration assembly includes a central core (250) projecting into the housing (210) and surrounded by filter material (242). The housing (210) may be collapsible around the filter material (242) to aid in the flow of the fluid and minimize hold-up fluid upstream of the filtration device (100).

    摘要: Improved devices (1) for blood separations are provided based on the use of hollow fiber membrane arrays (6) in extra-lumenal crossflow filtration. Blood is processed extra-lumenally across an ordered array of microporous hollow fibers (6) to separate cells from plasma. By use of extra-lumenal crossflow filtration with suitably oriented fibers, the separation device is more efficient than existing devices which benefits a patient or donor by reducing extracorporeal volume.

    摘要: A liquid filtration device (129) useable for removing leukocytes from blood contains a first chamber (108) which is in fluid flow relationship with a second chamber (109). Filtration elements (103) separate the first chamber (108) from the second chamber (109) so that the liquid flowing from the first chamber (108) is filtered thereby prior to entry into the second chamber (109). A passage (111) leads from the second chamber (109) into the first chamber (108) and a hydrophobic filter (104) is used to prevent liquid from the first chamber (108) from flowing through the passage (111) into the second chamber (109) while allowing air to flow therethrough. An outlet (123) is located in the second chamber (109). A second outlet (124) is located within the second chamber (109) and is placed in fluid flow relationship therewith by a conduit (116).

    摘要: Filters (hollow-fibers, flat-sheet membranes or depth filters) for removing leukocytes and viral inactivating agents from whole blood or blood fractions are disclosed. One type of depth filter comprises a laid textile web which has been modified to attach a ligand for viral inactivating agents, a ligand for leukocytes, or ligands for both. An exemplary membrane comprises a polyethersulfone membrane that has been similarly modified. Filter devices for simultaneously removing leukocytes and viral inactivating agents from whole blood or blood fractions are also disclosed. One type of device comprises (1) a housing surrounding (2) activated carbon and (3) a mechanically stable polymeric material which may optionally be modified to attach a ligand for leukocytes. General methods for removing leukocytes and rival inactivating agents from blood are also disclosed.
