A blood irradiator

Abstract

The invention relates to the technical field of medical equipment and particularly discloses a blood irradiation instrument based on X rays. The blood irradiation instrument comprises a high-voltage generator, an X-ray tube cooling system, an X-ray tube, an irradiation control and management system, a blood-bag storage and rotating mechanism and a body, wherein the high-voltage generator, the X-ray tube cooling system and the irradiation control and management system are all arranged on the body; the body is internally provided with a protective chamber; in the sealed protective chamber, the X-ray tube can emit 360-degree ring-shaped and conical X-ray beams to irradiate blood in a cavity body on a disc bracket; since a motor drives the cavity body to rotate around the X-ray tube, the blood and biological tissues and the like can receive uniform irradiation dosage and good uniformity of irradiation is ensured; the irradiation control and management system controls the high-voltage generator to drive the X-ray tube to carry out irradiation, so that the irradiation dosage can be controlled; and all the irradiation is in the protective chamber, so that good safety is ensured, other protective means are not needed and the medical cost is reduced.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an X-ray-based blood irradiation instrument. Background technique [0002] Blood irradiation means that after the blood is irradiated with X-rays or γ-rays, the lymphocytes with immune function are inactivated and the functional activity of other cells is maintained. Lymphocytes are mixed in human platelets or fresh blood. When this allogeneic blood or blood components containing a large number of immune-competent lymphocytes are transfused into immunocompromised patients, transfusion-associated graft-versus-host disease (TA- The occurrence of GVHD) can lead to the death of patients in severe cases. Irradiating blood or blood products with radiation can effectively inactivate immune-active T lymphocytes in the blood, and transfusion of radiation-irradiated blood or blood components can effectively prevent the occurrence of TA-GVHD and make blood transfusion safer.

AI Technical Summary

Problems solved by technology

According to the prevention mechanism of TA-GVHD, blood irradiation equipment uses X-ray device or γ-ray radiation source to control the dose of radiation to irradiate blood and blood products. It is a special equipment for irradiating blood. Radiation is harmful to the human body, and it is difficult to protect, and the radiation of radioactive elements is always in a state of radiation. Therefore, it is necessary to do a good job in radiation protection and management of radioactive elements, which increases medical costs.
