c) unidirectional valve (8) is connected to the porous permeable membrane (9A) to allow unpurified blood into the membranes (16, 17) using the channel (11);

d) a chamber (26) is connected to membranes (16, 17) through channel (13) to store L1 solution provided with bubble trapper valve (25) to prevent entry of air bubbles into the chamber (26);

e) outlets of chambers (18, 15) are connected to waste outlet (19) through channel (19A, 19B) respectively to carry impure L2 solution; and

f) outlets of membranes (17,16) are connected to purified blood outlet (20) through channels (20A, 20B) respectively to circulate purified blood to veins.

2. ) The apparatus as claimed in claim 1, wherein the flow of L2 solution into the chambers (15, 18) is controlled using knobs (2, 3).

3. ) The apparatus as claimed in claim 1, wherein knob (1) is used to control the flow of impure blood and L1 solution into the membranes (17, 16), and allows either the impure blood or the L1 solution into a membrane (17, 16) at any given time and maintains impure blood in any one of the membranes (17, 16) and L1 solution in the other membrane (17, 16).

4. ) The apparatus as claimed in claim 1, wherein knob (1A) is used to control the flow of pure blood from the membranes (17, 16) through the channels (20A, 20B) to the outlet (20) and opens one of the channels (20A, 20B) at any given time.

5. ) The apparatus as claimed in claim 1, wherein valves (4, 5) are used to control the flow of L2 solution from the chambers (15, 18) to the outlet (19) through channels (19A,19B).

6. ) The apparatus as claimed in claim 1, wherein valve (6) controls the removal of waste collected in impermeable jacket (9) through the outlet (19).

7. ) The apparatus as claimed in claim 1, wherein said membranes (16, 17) are biocompatible and are made up of polymers selected from a group comprising polyvinyl halides, polyurethanes, polystyrene derivatives, polyolefins, polyester series condensates, cellulose series high polymers and combinations thereof and said polyurethanes selected from a group comprising segmential polyurethanes and polyurethane urea.

8. ) The apparatus as claimed in claim 1, wherein said polymer membranes (16, 17) are sandwiched between single/multi layered nano-carbon/bio-compatible medicated metallic or non metallic (nylon or any other polymeric or other materials) nets and said are placed in “

V”

shape.

9. ) The apparatus as claimed in claim 1, wherein said channel (11) is divided into two sub channels (11A, 11B) to connect membranes (17, 16) respectively.

10. ) A method of assembling an apparatus for purification of blood, wherein said method comprising steps of:

a) placing membranes (16, 17) in chambers (15, 18) respectively;

b) connecting impermeable jacket (9) having porous permeable membrane (9A) to the membranes (16, 17) through channel (11);

c) connecting chamber (26) to the membranes (16, 17) through channel (13);

d) connecting outlets of the chambers (18, 15) to waste outlet (19) through channel (19A, 19B) respectively and connecting outlets of the membranes (17,16) to purified blood outlet (20) through channels (20A, 20B) respectively; and

e) mounting valves (4, 5) on to said channel (19A, 19B) respectively to control flow of waste and fixing knobs (1, 1A) to control flow of unpurified blood through channel (11) and purified blood through channels (20A, 20B).

11. ) The method as claimed in claim 10, wherein knob (2, 3) are placed to control flow of L2 solution through channel (12) which is connected to chambers (15, 18).

12. ) The method as claimed in claim 10, wherein valves (27, 28) are placed to control flow of L1 solution into membranes (17,16) through sub channels (11A, 11B).

13. ) The method as claimed in claim 10, wherein said polymer membranes (16, 17) are placed in “

V”

shape.

14. ) The method as claimed in claim 10, wherein said polymer membranes (16, 17) are sandwiched between single layered nano-carbon nets.

15. ) A method for purification of blood, wherein said method comprising steps of:

a) allowing impure blood to undergo coarse filtration through porous permeable membrane (9A) to remove the waste through outlet (19);

b) directing coarse filtered impure blood using knob (1) into one of the membranes (16 or 17) to undergo filtration while refreshing the other membrane (16, or 17) using L1 and L2 solution at a given time; and

c) collecting waste material into L2 solution after filtration and thereby removing the waste through the outlet (19) to obtain purified blood in outlet (20).

16. ) The method as claimed in claim 15, wherein the filtration of blood involves removal of waste such as urea, uric acid, creatinine and other metabolites.

17. ) The method as claimed in claim 15, wherein the refreshment of membranes (16 and 17) involves removal of impurities which are blocked inside the membranes (16 or 17) and maintaining L1 solution inside the membrane (16 and 17) and L2 solution outside the membrane (16 and 17) but inside the chamber (15, 18).
