1. A device, comprising:
- i) a fluorescent source of electromagnetic radiation comprising a plurality of tubular bulbs, each of said bulbs having first and second ends and a middle region;
ii) a blood bag support configured such that at least a portion of said electromagnetic radiation from said bulbs contacts a blood bag when positioned on said support; and
iii) a means for allowing said contact of electromagnetic radiation from at least a portion of said middle region while preventing said contact of electromagnetic radiation from at least a 2 cm portion of each of said first and second ends.

Abstract
Methods and compositions are described for treating contaminants in material intended for in vivo use, and in particular blood and blood products for human use. Contaminants in blood cell preparations are inactivated prior to long term storage and transfusion. Inactivation is accomplished using a device having a unique temperature control design.

7. A device, comprising:
-
i) a fluorescent source of electromagnetic radiation comprising a plurality of tubular bulbs, each of said bulbs having first and second ends and a middle region, wherein the first and second ends generate substantially more heat than the middle region;
ii) a blood bag support configured such that at least a portion of said electromagnetic radiation firm said bulbs contacts a blood bag when positioned on said support; and
iii) a means for controlling the temperature of the blood bag when positioned on said support by allowing said contact of electromagnetic radiation from at least a portion of said middle region while preventing at least a portion of the heat generated from each of said first and second ends from contacting the blood bag. - View Dependent Claims (8)
