20090139924 | Biological fluid filtration apparatus - Apparatus for use in a biological fluid processing or fluid filtration system is provided. The biological fluid processing or fluid filtration system has novel open and closed loop processing systems wherein the gases transferred into and out of the system during processing pass through a porous medium in upstream and/or downstream gas inlet or outlet housings or vents in a manner which precludes the fluid being processed or filtered from ever contacting the housings or vents. Each housing or vent is separated from the fluid by a column of gas in its respective transfer line. The upstream gas inlet housing or vent is in communication with the unfiltered biological fluid, and the downstream gas inlet housing or vent is in communication with the filtered biological fluid. | 06-04-2009 |
20090270837 | MULTI-PURPOSE TUBING APPARATUS - An improved tubing device, preferably for use in the medical industry is provided. The tubing device provides a seamless transport path by using the tubing itself as the transport means without any other internally wetted parts, or connections, to provide a substantial reduction in the number of fluid contact components, and eliminate the need for cutting tubes into segments to be later bonded via tubing connectors. This can reduce the risk of contamination of the transported materials and can also reduce the use of chemicals such as adhesives and bonding agents. | 10-29-2009 |
20100108592 | BIOLOGICAL FLUID FILTRATION SYSTEM UTILIZING BY-PASS LINE AND TUBE SUPPORT DEVICE - An improved biological fluid filtration system is shown having, seriatim, a blood container, a biological fluid filtration device downstream of the blood container, and a blood receiving container downstream of the biological fluid filtration device; a bypass line is provided to allow fluid communication between the blood container and the blood receiving container, the bypass line includes a loop, the loop of the bypass line being configured to be disposed above the blood container at a sufficient height to prevent the passage of fluid around the leukocyte depletion device; the loop of the bypass line being disposed in a tube support device, the tube support device being configured to support substantially the entire weight of the biological fluid filtration system without substantially crimping said bypass line. | 05-06-2010 |
20100140150 | Biological Fluid Filtration System and Biological Fluid Filter Used Therein - A biological fluid processing or fluid filtration system is provided having novel open and closed loop processing systems wherein the gases transferred into and out of the system during processing pass through a porous medium in upstream and/or downstream gas inlet or outlet housings or vents in a manner which precludes the fluid being processed or filtered from ever contacting the housings or vents. Each housing or vent is separated from the fluid by a column of gas in its respective transfer line. The upstream gas inlet housing or vent is in communication with the unfiltered biological fluid, and the downstream gas inlet housing or vent is in communication with the filtered biological fluid. | 06-10-2010 |
20110024349 | Filter Media Surface Modification for Enhanced Sealing and Apparatus Utilizing the Same - A novel surface treatment is provided for portions of filter media coming in contact with the filter media holder, such as filter housing. In certain applications, the treatment is also applied to the filter media holder, depending on the application. Filter media having at least two distinct surface property modifications are provided in liquid filtration applications to enhance the performance of a filtration system, reduce the cost of the system, provided a visual means of detecting fluid bypass, and minimize fluid holdup volume within the filter media, all with substantially no loss of performance performances parameters, even in steam sterilization applications. | 02-03-2011 |
20110163024 | BIOLOGICAL FLUID FILTRATION SYSTEM AND BIOLOGICAL FILTER USED THEREIN - A biological fluid processing or fluid filtration system is provided having novel open and closed loop processing systems wherein the gases transferred into and out of the system during processing pass through a porous medium in upstream and/or downstream gas inlet or outlet housings or vents in a manner which precludes the fluid being processed or filtered from ever contacting the housings or vents. Each housing or vent is separated from the fluid by a column of gas in its respective transfer line. The upstream gas inlet housing or vent is in communication with the unfiltered biological fluid, and the downstream gas inlet housing or vent is in communication with the filtered biological fluid. | 07-07-2011 |
20120181236 | PRECHARGABLE FLUID FILTRATION METHOD AND APPARATUS - A fluid filtration apparatus is provided which includes at least a functional biomedical device having an inlet and an outlet, a first biological fluid container in fluid communication with the inlet of said functional biomedical device, a first biological fluid receiving container downstream of the functional biomedical device in fluid communication with the outlet of the functional biomedical device, and having an excess of fluid, such as air or gas, in the first biological fluid container or biological fluid receiving container (either placed therein during manufacture, or added later) sufficient to drain the system. A method of using the apparatus is disclosed. | 07-19-2012 |
20140171883 | Hemostatic Agent and Method - One aspect of the invention is a method of treating a wound to clot blood. A sponge material is applied to the wound. The sponge comprises a starch having hemostatic properties and at least one binding agent. The sponge may further comprise a porous, flexible material. | 06-19-2014 |
