X-ray blood irradiator device

Abstract

The invention discloses an X-ray blood irradiation device, which comprises a frame, an X-ray source, a blood bag container and a high-voltage generator. The X-ray source and the blood bag container are arranged on the frame, and the X-ray The source includes an X-ray tube assembly and a vacuum assembly, the X-ray tube assembly includes an anode, a cathode, a first tube body and a second tube body, the first tube body and the second tube body are detachably connected to form an X-ray tube body, and the cathode and The anode is arranged in the X-ray tube body, the anode is detachably connected to the first tube body, the cathode and the anode are facing each other and detachably connected to the second tube body, and the vacuum assembly is used to evacuate the X-ray tube body of the X-ray tube assembly , the high-voltage generator is connected to the cathode through a high-voltage cable. Compared with the prior art, the operating cost of the X-ray blood irradiation apparatus of the present invention is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of blood irradiation instruments, in particular to an 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] At present, it is considered that irradiation of blood products before blood transfusion is the only effective way to prevent TA-GVHD. The mechanism is: lymphocytes are sensitive to radiation, and the appropriate dose of radiation can inactivate immune-competent lymphocytes and lose their abilit...

Problems solved by technology

[0006] However, X-ray tubes used in X-ray blood irradiator devices are expensive and have a limited lifespan

At present, the X-ray tube used in the X-ray blood irradiation device generally adopts the longest-lived metal-ceramic X-ray tube, and the cumulative exposure can reach more than 2,000 hours. However, the lifespan is only about one year, and the price is extremely high.

Under normal circumstances, the main reasons for the scrapping of metal-ceramic X-ray tubes are: the release of gas from the internal material makes the vacuum degree drop, sparking, damage to the cathode, damage to the anode, etc.
