Claims
- 1. A blood treatment device, comprising:
i) a fluorescent bulb; ii) a light filtration material configured to remove a blood damaging wavelength of electromagnetic radiation emitted by the fluorescent bulb to produce filtered electromagnetic radiation; and iii) a blood bag support configured such that at least a portion of the filtered electromagnetic radiation from the bulb contacts a blood bag when positioned on the support.
- 2. The device of claim 1, wherein the material removes a blood product damaging wavelength that is absorbed by a nucleic acid.
- 3. The device of claim 1, wherein the material removes a blood product damaging wavelength that is absorbed by a protein.
- 4. The device of claim 1, wherein the material removes a blood product damaging wavelength that is absorbed by hemes.
- 5. The device of claim 1, wherein the material removes blood product damaging wavelengths that are absorbed by a nucleic acid, a protein and hemes.
- 6. The device of claim 5, wherein said filtered electromagnetic radiation has wavelengths between 320 and 400 nm.
- 7. The device of claim 1, wherein the blood bag support comprises said light filtration material, and said light filtration material comprises a short wavelength cutoff filter.
- 8. The device of claim 7, wherein the short wavelength cutoff filter is a 320 nm cutoff filter.
- 9. The device of claim 8, wherein said filtered electromagnetic radiation has wavelengths between 320 and 400 nm.
- 10. The device of claim 1, wherein said filtered electromagnetic radiation has a wavelength that is absorbed by flavins.
- 11. A method of treating a blood product in a blood bag, comprising:
a) providing i) a blood bag comprising a photoreactive compound and a blood product suspected of containing a pathogen and ii) a blood treatment device comprising a fluorescent bulb, a light filtration material configured to remove a blood damaging wavelength of electromagnetic radiation emitted by the fluorescent bulb to produce filtered electromagnetic radiation, and a blood bag support configured to receive the filtered electromagnetic radiation; b) positioning the blood bag on the blood bag support; and c) irradiating the blood bag with the filtered electromagnetic radiation so as to activate the photoreactive compound and inactivate the pathogen.
- 12. The method of claim 11, wherein the light filtration material removes a blood product damaging wavelength that is absorbed by a nucleic acid and a protein.
- 13. The method of claim 12, wherein the material removes blood product damaging wavelengths that are absorbed by a nucleic acid, a protein and hemes.
- 14. The method of claim 13, wherein said filtered electromagnetic radiation has wavelengths between 320 and 400 nm.
- 15. The method of claim 11, wherein the photoreactive compound is a psoralen.
- 16. The method of claim 15, wherein the blood product comprises plasma.
- 17. The method of claim 16, wherein the blood product comprises platelets.
- 18. A method of treating a blood product in a blood bag, comprising:
a) providing i) a blood bag comprising a photoreactive compound and a blood product suspected of containing a pathogen and ii) a blood treatment device comprising a fluorescent bulb and a blood bag support, wherein the end of the fluorescent bulb is blocked from irradiating the blood product; b) positioning the blood bag on the blood bag support; and c) irradiating the blood bag with the fluorescent bulb so as to activate the photoreactive compound and inactivate the pathogen.
- 19. The method of claim 18, wherein the photoreactive compound is a psoralen.
- 20. The method of claim 19, wherein the blood product comprises plasma.
- 21. The method of claim 20, wherein the blood product comprises platelets.
