Description

X-ray blood irradiator

Technical Field

An X-ray blood irradiator belongs to the technical field of blood irradiation.

Background

Transfusion-associated graft-versus-host disease (TA-GVHD) is a fatal complication of transfusion in which immunocompetent lymphocytes in transfused blood cannot be removed, transplanted in vivo, proliferated, identified as non-self substances in tissues and organs of a patient, and targeted for immune attack and destruction. The clinical manifestations of transfusion-related graft-versus-host disease are lack of specificity, and easy to miss diagnosis and misdiagnosis. There are studies showing that: the number of the input lymphocytes of the receptor causing the transfusion-related graft-versus-host disease is more than 107/kg, and if the number of the input lymphocytes is less than 105/kg, the transfusion-related graft-versus-host disease cannot be caused. However, only 104/kg lymphocytes can cause transfusion-related graft-versus-host disease in the case of immunodeficient children. In general, the higher the number of lymphocytes transfused into the donor, the more severe the disease, and the higher the mortality rate.

To date, irradiation of blood products prior to transfusion is the only effective method for preventing transfusion-associated graft-versus-host disease by: the lymphocyte is sensitive to radiation, and through proper radiation irradiation, the immunocompetent lymphocyte can be inactivated to lose the proliferation capacity, and the function of red blood cell and platelet and the activity of blood coagulation factor are not greatly influenced. The blood irradiator is a medical device which uses rays to irradiate blood or blood products, inactivates lymphocytes and prevents transfusion-related graft-versus-host disease in transfusion activities. From the radiation source, the blood irradiator can be classified into two types, one is to irradiate blood or blood products with gamma rays generated by a radiation source (mainly Cs-137, Co-60), and the other is to irradiate blood or blood products with X rays generated by an X-ray tube. Radioactive source type blood irradiator apparatuses require the assembly of several hundred to thousands of curie isotope radioactive sources, which presents a potential risk of nuclear leakage. The X-ray source type blood irradiator has no risk of nuclear leakage, and no ray is generated when the equipment is powered off. In order to avoid leakage of X-ray, the bulb tube of the existing X-ray source type blood irradiator is integrally arranged in an irradiation chamber, so that the irradiation chamber is large in volume, the wall of the irradiation chamber is made of lead with certain thickness, and two sides of the lead are provided with stainless steel plates for protecting the lead, so that the equipment is heavy, the occupied space is large, and the use is inconvenient.
