Abstract

Provided herein is an innovative hemoperfusion system and method including a thermal-fused broad-spectrum biocidal iodinated interactive polymer for the treatment of biological contaminants in body fluids. In one exemplary embodiment, the system and method utilizes a Triosyn® thermal fused broad-spectrum iodinated interactive polymer, included in a hemoperfusion column, for devitalizing high levels of cell-free microorganisms in whole blood and biological fluids in relation with the characterization of blood cells viability and function post-treatment.

Claims (17)

1. A hemoperfusion filtration system, comprising:

a) a centrifuge for whole blood to provide a red blood cell concentrate;

b) a dilution unit for diluting said red blood cell concentrate;

c) a chamber containing a demand disinfectant iodinated resin and a plurality of diffusers for maximizing the contact of said diluted red blood cell concentrate and said iodinated resin; and

d) a pump for moving said diluted red blood cell concentrate through said chamber at a selected flow rate.

2. The hemoperfusion filtration system of claim 1 , wherein said chamber is composed of a filter capsule, inlet end cap and a first mesh and a second mesh, wherein said inlet end cap is located close to said first mesh.

3. The hemoperfusion filtration system of claim 2 , wherein said filter capsule comprises the plurality of diffusers present between said first mesh and said second mesh.

4. The hemoperfusion filtration system of claim 1 , further comprising: c′)a centrifuge for removing residual plasma that is present in said diluted red blood cell concentrate after passage through said chamber; and f′) a filter for removing leukocytes.

5. The hemoperfusion filtration system of claim 1 , further comprising: e′″) a transfusion unit for transfusing said diluted red blood cell concentration after passage of said column into a human.

6. The system as in claim 1 , wherein said centrifuge centrifuges said blood at 37° C. at 3200 RPM for five minutes.

7. The system as in claim 1 , wherein said dilution unit dilutes said red blood cell concentrate using saline or other acceptable physiological fluid at 37° C.

8. A portable hemoperfusion filtration system, comprising:

a) a means for removing plasma from whole blood to provide a red blood cell concentrate;

b) a dilution device for diluting said red blood cell concentrate;

c) a chamber containing a demand disinfectant, said demand disinfectant being an iodinated resin contained in said column; and

d) a pump for moving said diluted red blood cell concentrate a blood constitute through said chamber column at a selected flow rate.

9. A hemoperfusion filtration chamber comprising a demand disinfectant iodinated resin and a plurality of hydrodynamnic diffusers, wherein the diffusers function to increase the contact efficacy between the iodinated resin and bacteria in blood that is passed through said chamber.
