Problems solved by technology

A disadvantage of this type of device is that if two units of blood or blood products are filtered through the device and collected into two separate receiving blood bags, the first unit will be utilized by the device in a relatively uncontaminated state. dirty (non-fouled) state of the filter element of the device is filtered, and the second unit will be filtered by the device using the filter element of the device in a relatively fouled state

Embodiment Construction

[0026] exist Figure 1 to Figure 5 One embodiment of a biological fluid filtration system constructed in accordance with the principles of the present invention is shown in . figure 1 The illustrated biological fluid filtration system 1000 includes feed blood 98, a first receiving blood bag 99, and a second receiving blood bag 99a. A biological fluid filter device (BFFD) 100 is interposed between the feeder blood bag 98 and the two receiver blood bags. A diaphragm drain (DDD 50 ) may be interposed between the feed blood bag 98 and the BFFD 100 . A first section of tubing 81 connects the outlet of the feed blood bag 98 to the inlet tube socket 51 of the DDD 50 . A second section of tubing 81 a connects the outlet header 52 of the DDD 50 to the inlet header 6 of the BFFD 100 . A third section of tubing 82 connects the first outlet hub 28 of the BFFD 100 to the inlet of the first receiving blood bag 99 . A fourth section of tubing 82a connects the second outlet hub 28a of the...

Abstract

A biological fluid filtration device, system, and method, for filtering a biological fluid, the device comprising a housing having an inlet, a first outlet and a second outlet, with a first fluid flow path defined between the inlet and the first outlet, with a second fluid flow path defined between the inlet and the second outlet, with a first biological fluid filtration media interposed between the inlet and the first outlet and across the first fluid flow path, with a second biological fluid filtration media interposed between the inlet and the second outlet and across the second fluid flow path, the housing essentially lacking a solid partition wall between the first biological fluid filtration media and the second biological fluid filtration media, a first flow restriction may be added downstream of the first biological fluid filtration media, and a second flow restriction may be added downstream of the second biological fluid filtration media, in another embodiment, the device comprises a housing having an inlet an outlet with a flow path defined between the inlet and the outlet, with a biological fluid filtration media interposed between the inlet and the outlet and across the fluid flow path, the device further including a flow restriction downstream of the biological fluid filtration media.

Description

technical field [0001] The present invention relates to the field of filtration, and more particularly, to improved low hold up (lowhold up) biological fluid filtration systems, including low hold up double sided biological fluid filtration devices, which are free of partition walls and capable of filtering biological fluids, including from Removal of components or chemicals from blood or blood products, including removal of white blood cells from packed red cells and removal of prions from blood or blood products. Background technique [0002] In US Patent No. 6,660,171 B2, filed March 27, 2001, entitled "HIGH CAPACITY GRAVITY FEED FILTER FOR FILTERING BLOOD AND BLOOD PRODUCTS," a dual-sided biological fluid filtration device is disclosed that includes a single inlet and a single outlet and a dividing wall. A double-sided biological fluid filtration device comprising a septum is disclosed in patent application Ser. No. 10 / 934,881, filed September 3, 2004, entitled "A BIOLOG...
