Embodiment

[0024] Embodiment: A miniaturized blood irradiation device, including a blood cup 1 , a plurality of radiation sources, a plurality of radiation source tube racks 2 , a radiation shield and a box 3 . Wherein, the radioactive source tube racks are tubular, and one radioactive source is placed in each radioactive source tube rack, one end of the radioactive source tube rack is a closed end, and the other end is an open end, which is used for placing and replacing the radioactive source. Each radioactive source is connected with a cable, which is connected with the box body or the replacement cover through the cable, so that the radioactive source is fixed at the set position.

[0025] The radiation shield is located in the box, which includes a vertically arranged outer shield 4 and an inner shield 5, the outer shield is columnar, and the outer shield is provided with a limit hole that runs through its two ends. The hole is an eccentric hole, and the side wall of the limiting ho...

Abstract

The invention discloses a miniaturized blood irradiation device which comprises a blood cup, a plurality of radioactive sources, a plurality of radioactive source pipe racks, a radiation shielding cover and a box body. According to the blood irradiation device, a thin shielding system can be selected, so that the piece weight of the device is reduced, the device has better mobility, meanwhile, the energy consumption of the device is greatly reduced, the reliability, maintainability, replaceability, combination, integration and the like of the device are greatly improved compared with those of commercially available products, and the device can be used for medical treatment and public health departments and units which need to use irradiation blood in urban blood centers, surgical hospitals and field hospitals.

Description

technical field [0001] The invention relates to the technical field of radiation equipment, in particular to a miniaturized blood irradiation device. Background technique [0002] Transfusion-associated graft-versus-host disease (TA-GVHD) is when immunocompromised or immunosuppressed patients cannot clear the blood transfused into their own immune-competent lymphocytes, making them engraft and proliferate the patient's tissues and organs in vivo. A fatal complication of transfusion that is recognized as non-self and targeted for immune attack and destruction. The purpose of irradiating blood is to inactivate T lymphocytes in blood products to the greatest extent, and to keep active blood components such as red blood cells, platelets, and granulocytes from being greatly damaged. [0003] The radiation sources used in commercially available blood irradiation devices mainly include X-ray generators and radioisotope sources. Blood irradiated by these two radiation sources has c...
