Description

technical field

[0001] The invention relates to the technical field of radiation equipment, in particular to a miniaturized blood irradiation device. Background technique

[0002] Transfusion-associated graft-versus-host disease (TA-GVHD) is when immunocompromised or immunosuppressed patients cannot clear the blood transfused into their own immune-competent lymphocytes, making them engraft and proliferate the patient's tissues and organs in vivo. A fatal complication of transfusion that is recognized as non-self and targeted for immune attack and destruction. The purpose of irradiating blood is to inactivate T lymphocytes in blood products to the greatest extent, and to keep active blood components such as red blood cells, platelets, and granulocytes from being greatly damaged.

[0003] The radiation sources used in commercially available blood irradiation devices mainly include X-ray generators and radioisotope sources. Blood irradiated by these two radiation sources has c...
