Abstract

The invention provides a single X-ray source blood irradiator and a irradiation method thereof, and belongs to the technical field of blood irradiators. The single X-ray source blood irradiator comprises a frame and an X-ray tube disposed on the frame. A blood bag carrying device is disposed under the X-ray tube, the blood bag carrying device is composed of a bottom plate, and an outer wall and an inner wall disposed in the bottom plate, a ring-shaped blood bag containing cavity is formed between the outer wall and the inner wall, the blood bag containing cavity is used for containing blood or a blood product to be irradiated, the bottom plate of the blood bag carrying device is movably disposed on the frame through a rotating shaft, and the rotating shaft is connected with an output shaft of a rotary motor through a transmission member. The single X-ray source blood irradiator fully utilizes X rays emitted from the X-ray tube, the efficiency of utilization can be raised, the rotary motor can make the blood bag carrying device rotate, the blood or the blood product in the blood bag can be forced to flow, the blood or the blood product in local areas can change positions, so the blood or the blood product can be more uniformly irradiated.

Description

technical field [0001] The invention relates to the technical field of blood irradiation apparatus, in particular to a single X-ray source blood irradiation device and an irradiation method using the single X-ray source blood irradiation device. Background technique [0002] Transfusion-associated graft-versus-host disease (TA-GVHD) is the inability of immunocompromised or immunosuppressed patients to remove immune-competent lymphocytes in the transfused blood, allowing them to engraft and proliferate in vivo, and identify the patient's tissues and organs as non- It is a deadly blood transfusion complication in which the target is immune attacked and destroyed. The clinical manifestations of TA-GVHD lack specificity, and it is easy to miss and misdiagnose. [0003] Studies have shown that the number of recipient lymphocytes that cause TA-GVHD should be greater than 10 7 / kg, if less than 10 5 / kg will not cause TA-GVHD. However, it has been reported that only 10 4 / kg l...
