摘要： Biological fluid filtration systems including biological fluid filtration devices capable of filtering blood or blood products, including the removal of leukocytes from the blood or blood product. Each system includes a means to automatically drain the biological fluid upstream of the biological fluid filtration media disposed in the biological fluid filtration device. Both single sided and double sided biological fluid filtration devices are disclosed, including double sided biological fluid filtration devices with a solid partition wall with a first independent fluid flow path on one side of the partition wall, and a second independent fluid flow path on the other side of the partition wall. Draining means include vent filtration devices, diaphragm draining devices, and biological fluid filtration devices that include an integral diaphragm. The biological fluid filtration devices include low hold-up volume filter underdrains that purge in excess of 95% of the initial air in the device before liquid begins to flow from the outlet, thereby allowing the devices to be used in bed side applications. Variable surface area biological fluid filtration devices are disclosed that further reduce hold-up volume.

摘要： A liquid filtration device useable for removing leukocytes from blood contains a first chamber which is in fluid flow relationship with a second chamber. Filtration elements separate the first chamber from the second chamber so that liquid flowing from the first chamber is filtered thereby prior to entry into the second chamber. A passage leads from the second chamber into the first chamber and a hydrophobic filter may be used to prevent liquid from the first chamber from flowing through the passage into the second chamber while allowing air to flow therethrough. An outlet is located in the second chamber, preferably at the bottom thereof. A second outlet may be located within the second chamber and may be placed in fluid flow relationship therewith by a conduit or the like.

摘要： An in-line liquid filtration device useable for filtration of blood, blood products or the like includes a housing having an inlet port, an outlet port, at least one filter element disposed in the housing between the inlet port and outlet port so as to filter liquid which flows into the filtration device via the inlet port. The filter element divides the housing into a first chamber and a second chamber. The device allows gases to vent the filtration device through the outlet port. The means may include a flow deflector within the first chamber and/or the second chamber. The means may also include a channel, preferably spiral, within either the first chamber and/or second chamber. The filtration device allows air therein to be purged downstream into either an air collecting bag or into the blood receiving bag without the manipulation of the height of the filtration device or the blood receiving bag.

摘要： The filtration method involves processing biological liquid from an enclosed flexible supply bag to a filtration media within a processing system wherein the flow of biological liquid within the system is restricted to allow the biological liquid to back up above the level of a port located upstream within the system and preventing gas from entering into the processing system through the port by maintaining the level of biological liquid above the port until the flow of biological liquid from the flexible supply bag ceases. The system automatically allows gas to enter into the system through the port when the flow of biological liquid ceases thereby draining the biological liquid into a receiving bag. The flow may be restricted by a narrow cross-sectional area within the processing system and the port may be covered by a hydrophobic filter media.

摘要： A flow diverter, vacuum control and tilting of the liquid filtering system are used alternatively or in conjunction to reduce foam production in a filtered liquid sample. A liquid filtering system includes an upper sample reservoir, a filter and a lower storage bottle. A vacuum is applied below the sample filter to draw sample liquid through the sample filter into the storage bottle. A flow diverter may be used to direct flow of the filtered liquid sample onto a sidewall of the storage bottle or guide flow to a bottom of the storage bottle. The vacuum may be regulated to reduce foaming. The liquid filtering system may be tilted to direct fluid to the sidewall of the lower storage bottle and reduce foaming.

摘要： A vacuum filtration apparatus for detecting microorganisms and particulates in liquid samples. The apparatus includes a base, an absorbent pad, a filter means, a funnel and a lid. The funnel is releasably attached to the base, and may contain an integral flexible seal for releasably sealing the filter means to the base. The outer wall of the lid may be segmented to make it flexible, this flexibility allows it to be releasably attached to the funnel or the base. The apparatus is designed so that any funnel will fit any base, and any lid will fit any base or any funnel when all parts are manufactured to normal tolerances. The apparatus may contain a means to keep the filter means wrinkle free in both the dry and wet states.
