Description
Technical Field
The invention belongs to the technical field of medical equipment, and particularly relates to a uniform single X-ray source blood irradiation instrument.
Background
Transfusion-related graft versus host disease (TA-GVHD) is a fatal transfusion complication in which immunocompromised or immunosuppressed patients cannot clear immunocompetent lymphocytes in the input blood, allow them to engraft and proliferate in the body, recognize the tissues and organs of the patient as nonhexon substances, and perform immune attack and destruction as target targets. Transfusion-related graft versus host disease is clinically manifested as a lack of specificity, and is extremely prone to missed and misdiagnosis. There are studies showing that: the number of recipient infused lymphocytes that cause transfusion-associated graft-versus-host disease should be greater than 107/kg, and below 105/kg would not cause transfusion-associated graft-versus-host disease. However, only 104/kg lymphocytes in immunocompromised children trigger transfusion-associated graft versus host disease. In general, the greater the number of lymphocytes infused into the donor, the more severe the condition and the higher the mortality.
In the present day, irradiation of blood products prior to transfusion is the only effective method for preventing transfusion-associated graft versus host disease, the mechanism of which is: lymphocytes are sensitive to radiation, and through proper dosage of radiation, immunocompetent lymphocytes can be inactivated, proliferation capacity is lost, and functions of erythrocytes and platelets and activity of blood coagulation factors are not greatly influenced. The blood irradiator is a medical device for inactivating lymphocytes by irradiating blood or blood products with rays and preventing graft versus host disease related to blood transfusion in blood transfusion activities. From the radiation source, blood irradiation instruments can be classified into two types, one type of which irradiates blood or blood products with gamma rays generated by a radiation source (mainly Cs-137, co-60), and the other type of which irradiates blood or blood products with X-rays generated by an X-ray tube. Radioactive-source blood-irradiation apparatus require the assembly of several hundred to thousands of curie isotope radioactive sources, which presents a potential risk of nuclear leakage. The X-ray type blood irradiator has no risk of nuclear leakage, and no rays are generated when the device is powered off.
In order to solve the problem of the radiation uniformity of the single X-ray tube, the existing mechanism needs to be improved, so that the problem of the radiation uniformity of the single X-ray tube is solved.
