Claims
- 1. An apparatus for controlling movement of fluids during an extracorporeal blood treatment session, comprising:a hollow enclosure having a plurality of fluid input ports for receiving said fluids into said enclosure and a plurality of fluid output ports for expelling said fluids from said enclosure; internal fluid passageways disposed within said hollow enclosure for coupling together said fluid input ports, and said fluid output ports; at least one internal valve disposed within said hollow enclosure and connected to at least one of said internal fluid passageways for controlling movement of said fluid within said hollow enclosure during said extracorporeal blood treatment session; a filter in said hollow enclosure and connected to at least one of said internal fluid passageways for filtering said fluid, and wherein said filter is adapted to pass whole blood and filter blood clots therefrom; and wherein said filter comprises a first chamber and a second chamber within the enclosure which are separated from each other by a filter media.
- 2. The apparatus of claim 1 wherein the filter media comprises a woven mesh.
- 3. The apparatus of claim 2 wherein the woven mesh comprises a polyester.
- 4. The apparatus of claim 1 wherein said first chamber is at least partially formed of a first layer of elastomeric membrane material disposed on a first outer surfaces of said hollow enclosure.
- 5. An apparatus for controlling movement of fluids during an extracorporeal blood treatment session, comprising:a hollow enclosure having a plurality of fluid input ports for receiving said fluids into said enclosure and a plurality of fluid output ports for expelling said fluids from said enclosure; internal fluid passageways disposed within said hollow enclosure for coupling together said fluid input ports, and said fluid output ports; at least one internal valve disposed within said hollow enclosure and connected to at least one of said internal fluid passageways for controlling movement of said fluid within said hollow enclosure during said extracorporeal blood treatment session; and a filter in said hollow enclosure and connected to at least one of said internal fluid passageways for filtering said fluid, and wherein said filter is adapted to pass whole blood and filter blood clots therefrom.
- 6. An apparatus for controlling movement of fluids during an extracorporeal blood treatment session, comprising:a hollow enclosure having a plurality of fluid input ports for receiving said fluids into said enclosure and a plurality of fluid output ports for expelling said fluids from said enclosure; internal fluid passageways disposed within said hollow enclosure for coupling together said fluid input ports, and said fluid output ports; at least one internal valve disposed within said hollow enclosure and connected to at least one of said internal fluid passageways for controlling movement of said fluid within said hollow enclosure during said extracorporeal blood treatment session; and a filter in said hollow enclosure and connected to at least one of said internal fluid passageways for filtering said fluid, and wherein said filter is adapted to filter blood clots from whole blood, wherein said filter comprises a first chamber and a second chamber within the enclosure which are separated from each other by a filter media, and wherein the filter media comprises a mesh having a pore size of about 200 microns.
- 7. An apparatus for controlling movement of fluids during an extracorporeal blood treatment session, comprising:a hollow enclosure having a plurality of fluid input ports for receiving said fluids into said enclosure and a plurality of fluid output ports for expelling said fluids from said enclosure; internal fluid passageways disposed within said hollow enclosure for coupling together said fluid input ports, and said fluid output ports; at least one internal valve disposed within said hollow enclosure and connected to at least one of said internal fluid passageways for controlling movement of said fluid within said hollow enclosure during said extracorporeal blood treatment session; and a filter in said hollow enclosure and connected to at least one of said internal fluid passageways for filtering said fluid, and wherein said filter is adapted to filter blood clots from whole blood, wherein said filter comprises a first chamber and a second chamber within the enclosure which are separated from each other by a filter media, and wherein the filter media comprises a mesh having a pore size between about 200 microns and about 400 microns.
- 8. An apparatus for controlling movement of fluids during an extracorporeal blood treatment session, comprising:a hollow enclosure having a plurality of fluid input ports for receiving said fluids into said enclosure and a plurality of fluid output ports for expelling said fluids from said enclosure; internal fluid passageways disposed within said hollow enclosure for coupling together said fluid input ports, and said fluid output ports; at least one internal valve disposed within said hollow enclosure and connected to at least one of said internal fluid passageways for controlling movement of said fluid within said hollow enclosure during said extracorporeal blood treatment session; a filter in said hollow enclosure and connected to at least one of said internal fluid passageways for filtering said fluid, and wherein said filter is adapted to filter blood clots from whole blood, wherein said filter comprises a first chamber and a second chamber within the enclosure which are separated from each other by a filter media; and air evacuation means for evacuating air from at least one of said first and second chambers.
- 9. An apparatus for controlling movement of fluids during an extracorporeal blood treatment session, comprising:a hollow enclosure having a plurality of fluid input ports for receiving said fluids into said enclosure and a plurality of fluid output ports for expelling said fluids from said enclosure; internal fluid passageways disposed within said hollow enclosure for coupling together said fluid input ports, and said fluid output ports; at least one internal valve disposed within said hollow enclosure and connected to at least one of said internal fluid passageways for controlling movement of said fluid within said hollow enclosure during said extracorporeal blood treatment session; a filter in said hollow enclosure and connected to at least one of said internal fluid passageways for filtering said fluid, and wherein said filter is adapted to filter blood clots from whole blood, wherein said filter comprises a first chamber and a second chamber within the enclosure which are separated from each other by a filter media; and a second filter in said hollow enclosure.
