X-ray blood irradiator

Abstract

The invention discloses an X-ray blood irradiator comprising an X-ray unit, a rotating carrier disc, an X-ray shielding case, an air-water cooler, a human-machine interface and an industrial personal computer. The X-ray unit comprises a metal ceramic X-ray tube, a high tension generator and a high-tension cable; the X-ray tube and the rotating carrier disc are disposed inside an irradiation chamber enclosed by the X-ray shielding case. A blood container is mounted on the rotating carrier disc. The rotating carrier disc is driven to rotate by a motor. A filter is added to a path of the X-ray emitted by the X-ray tube. Instead of radioisotopes, the X-ray unit is used as an irradiation source; the irradiator needs highly fewer shielding materials than a gamma-ray irradiator; the irradiator is small and portable and generates X-ray only when required; safety hazards are eliminated; the problem of disposal of nuclear waste is also avoided.

Description

Technical field [0001] The invention belongs to medical equipment, used for inactivating lymphocytes with immune activity in the blood, and specifically relates to an X-ray blood irradiator. Background technique [0002] The irradiation processing technology of blood (or blood products) has been widely used since the 1970s, especially for bone marrow transplant patients, leukemia patients or patients with weakened immune function. At present, most blood irradiators use radioisotope sources (such as commonly used cesium-137 and cobalt-60) to generate gamma rays, and selectively inactivate immunologically active lymphocytes in the blood by controlling the dose of radiation to prevent blood transfusion. The occurrence of graft-versus-host disease. The gamma-ray energy emitted by the isotope source is very high (the gamma-ray energy of cesium-137 is 662keV, and Co-60 emits 2 gamma-rays with energies of 1.17MeV and 1.33MeV respectively), which requires a lot of shielding and high-lev...

Problems solved by technology

The γ-ray energy emitted by the isotope source is very high (the γ-ray energy of cesium-137 is 662keV, and Co-60 emits 2 γ-rays with energies of 1.17MeV and 1.33MeV respectively), which requires a lot of shielding and high-level protection; The isotope source emits gamma rays continuously, and there are certain safety hazards in the blood bank and hospital environment; the isotope source will decay and needs to be calibrated regularly, and the irradiation time needs to be gradually extended; Disposal of the problem
