Abstract

The invention relates to a dialysis apparatus, comprising: a body with two planar sides, wells contained in the body, the wells being accessible from one planar side, a plurality of membranes for separating the wells into compartments, wherein each of said membranes is isolated one from another.

Claims (34)

1. A dialysis apparatus comprising:

a body with two planar sides, the body comprising an assembly of plates,

wells contained in the body, the wells being accessible from one planar side,

a plurality of membranes for separating the wells into compartments, wherein each of said membranes is isolated one from another, and

a carrier supporting a row of the membranes, each membrane being isolated one from another by the carrier;

wherein the carrier is of pressure sensitive adhesive material.

2. A dialysis apparatus, comprising:

a body with two planar sides,

wells contained in the body, the wells being open and accessible from one planar side, and closed on the other planar side,

a plurality of membranes for separating the wells into compartments, each of said membranes being isolated one from another,

at least one carrier, each of said carriers supporting a row of membranes.

3. The apparatus of claim 2 , wherein the carrier is of pressure sensitive material.

4. The apparatus of claim 2 , further comprising plates forming the body, the plates sandwiching the carriers.

5. The apparatus of claim 4 , the plates containing the compartments, a well being formed by a compartment of a plate facing a compartment of another plate.

6. The apparatus of claim 5 , wherein a recess surrounds each compartment, the membranes being received in the recesses.

7. The apparatus of claim 2 , wherein each of said membranes is in the form of a flat sheet.

8. The apparatus of claim 7 , wherein the membranes extend transversally to the planar sides.

9. The apparatus of claim 2 , further comprising plates, the body comprising an assembly of the plates, the plates sandwiching the membranes.

10. The apparatus of claim 9 , the plates containing recesses surrounding the compartments, the membranes being received in the recesses.

11. The apparatus of claim 9 , further comprising mechanical fastener for fastening the plates together.

12. The apparatus of claim 2 , each membrane being isolated one from another by the carrier.

13. The apparatus of claim 2 , wherein the carrier is comb-shaped with fingers delimiting cells for receiving the membranes.

14. The apparatus of claim 2 , comprising an 8×12 array of wells.

15. A method for assembling a dialysis apparatus, the dialysis apparatus comprising

a body with two planar sides,

plates forming the body, the plates containing compartments,

wells contained in the body, the wells being accessible from one planar side,

a plurality of membranes for separating the wells into compartments, wherein each of said membranes is isolated one from another,

at least one carrier supporting a row of membranes,

the method comprising the steps of:

providing said plates,

placing said carrier supporting a row of membranes between the plates, such that each of said membranes is isolated one from another,

fastening the plates together.

16. The method of claim 15 , wherein the at least one carrier is of pressure sensitive material, the step of fastening the plates consisting in exerting a pressure on the apparatus in order to cause the plates to stick together.
