Abstract

Provided is a filter apparatus, comprising two or more filter cartridges having a first end with an inlet and screen and a second end with an outlet and screen, and walls to contain a filter media held in a housing for holding the two or more filter cartridges in about the same orientation, and an attachment clamp connected to the housing. Also provided is a housing for holding two or more filter cartridges in about the same orientation and a method of using the filter apparatus and housing.

Claims

1. A filter apparatus, comprising:

two or more filter cartridges having a first end with an inlet and screen and a second end with an outlet and screen, and walls to contain a filter media;

a housing for holding the two or more filter cartridges in about the same orientation, and

an attachment clamp connected to the housing.

2. The filter apparatus of claim 1, wherein the housing comprises an upper plate and a lower plate for holding the two or more filter cartridges, the upper plate and the lower plate comprising openings for rotatably engaging the two or more filter cartridges, and

one or more support elements connecting the upper plate and the lower plate.

3. The filter apparatus of claim 2, wherein the attachment clamp is connected to one or more of the one or more support elements.

4. The filter apparatus of claim 2, wherein the one or more support elements comprise a combination of rods and support plates

5. The filter apparatus of claim 1, wherein the attachment clamp is a pole clamp.

6. The filter apparatus of claim 1, wherein the walls to contain the filter media comprise a cartridge tube.

7. The filter apparatus of claim 6, wherein the cartridge tube is transparent.

8. The filter apparatus of claim 1, wherein the inlet and outlet comprise an inlet connector and an outlet connector.

9. The filter apparatus of claim 8, wherein the outlet connector is connected to the cartridge tube by an outlet flange.

10. The filter apparatus of claim 9, wherein the outlet flange is conical.

11. The filter apparatus of claim 10, wherein the inlet connector is connected to the cartridge tube by an inlet flange.

12. The filter apparatus of claim 1, wherein the filter media comprises activated carbon.

13. The filter apparatus of claim 12, wherein the filter media is hydrogel coated activated carbon.

14. The filter apparatus of claim 1, wherein the walls to contain the filter media define a cylindrical shape.

19. A method of setting up a filter apparatus for a hemo filtration therapy, comprising attaching a filter apparatus according to claim 1 to an IV pole and rotating the cartridges to observe if there are lodged bubbles in the filter media.

20. The method of claim 19, wherein the housing is a connected structure.

15. A filter apparatus, comprising:

two filter cartridges having a first end with an inlet comprising an inlet connector connected to the cartridge tube by an inlet flange and screen and a second end with an outlet comprising an outlet connector and connected to the cartridge by a conical outlet flange and screen, and a transparent cartridge tube to contain a filter media;

a housing for holding the two filter cartridges in about the same orientation comprising an upper plate and a lower plate for holding the two filter cartridges, the upper plate and the lower plate comprising openings for rotatably engaging the two filter cartridges;

support elements comprising support plates and rods connecting the upper plat to the lower plate, and

a pole clamp connected to the support plates.

16. The filter apparatus of claim 15, wherein the filter media comprises activated carbon.

17. The filter apparatus of claim 15, wherein the cartridge tubes are comprised of a transparent material selected from the group consisting of a polysulfone, a polycarbonate, a polypropylene and an acrylic.

18. A housing for holding two or more filter cartridges in about the same orientation, comprising:

a connected structure comprising an upper plate and a lower plate, the upper plate and the lower plate comprising openings for rotatably engaging the two or more filter cartridges;

one or more support elements connecting the upper plate and the lower plate, and

an attachment clamp connected to the housing.
