Problems solved by technology

However, gamma ray devices such as cobalt sources (60Co) have the following shortcomings and deficiencies: 1. Difficulty in protecting the radioisotope system; 2. Waste disposal problems; 3. Continuous attenuation of isotope sources 4. The isotope dose rate cannot be adjusted; 5. Due to the hazards of isotopes, the country has a high threshold for isotope source supervision and equipment requirements (lead-lined rooms are required or corresponding safety precautions are required), and it is difficult to promote and other shortcomings. Serious Limits its application in the field of biomedical research

specific Embodiment 1

[0020] figure 2 It is a schematic diagram of an embodiment of an A-type high-energy X-ray biological irradiation apparatus of the present invention, showing an embodiment using a single radiation chamber 15 structure. In order to destroy the hematopoietic system of experimental animals or inactivate cells, the experimental animals or cells are placed in the irradiation room, and the required voltage, current, irradiation time and dose are automatically adjusted and controlled by the computer to generate high-energy X-rays for Irradiation of experimental animals or cells.

[0021] When the present invention is in use, one of A, B, and C type magnetic separators is selected according to the quantity and purpose of the cells to be separated.

specific Embodiment 2

[0022] like image 3 As shown, shown is the schematic diagram of the B-type high-energy X-ray biological irradiation instrument of the present invention, wherein the X-ray tube 16 is arranged in the radiation chamber 15, and like this, the radiation source is placed in the radiation chamber 15 shielded by a group of large inclination angles. 1. The high-power ceramic X-ray tube 16 produces high-energy X-rays in a state of 360-degree rotation to irradiate objects in the irradiation chamber 15 without dead ends. Described X-ray tube 16 is installed in the irradiation room 15 of radiation shielding and is connected with cooling system, to dissipate, reduce the heat that X-ray instrument produces; Lining and boron carbide, graphite and other materials are bonded to a closed space surrounded by polyvinyl fluoride inner shell, and X-ray tube 16 tube heads are installed in the irradiation room. The required voltage, current, irradiation time and dose are automatically adjusted and c...

specific Embodiment 3

[0023] like Figure 4 shown in image 3 The basic deformation is specifically generated by setting two sets of high-inclination and high-power ceramic X-ray tubes 161 and 162 in the irradiation chamber 15 to generate high-energy X-rays in a fixed state to irradiate the objects in the irradiation chamber with X-rays. The X-ray tube is installed in a radiation-shielded irradiation room and connected to a cooling system to dissipate and reduce the heat generated by the X-ray instrument; the radiation-shielded radiation room is made of a metal shell, a lead plate lining and Boron carbide, graphite and other materials are bonded to the enclosed space surrounded by the polyvinyl fluoride inner shell, and the X-ray tube head is installed in the irradiation room. The required voltage, current, irradiation time and dose are automatically adjusted and controlled by the computer to generate high-energy X-rays, which are used to irradiate organisms (experimental animals) of different siz...

Each X-ray pipe comprises a pipe head, a control end of the pipe head is connected with the high pressure generator and the output end of the cooling system, the pipe head is used for emitting the X-rays, the radiation chamber is a closed space and is used for shielding the X-rays, and the pipe head is arranged in the radiation chamber. The device can achieve energy X-ray irradiation on cells of specific animal organism or microorganism, plants and animals in the radiation chamber. The biological irradiation device is applicable to various scientific research fields such as bone marrow transplantation, human genomics, immunology, oncology phymatology, radioecology, cells, microorganism inactivation and sterilization of the animals infected with infectious microorganisms.

Description

technical field [0001] The invention relates to a novel laboratory device for providing high-energy rays for biological ionizing radiation, in particular to a high-energy X-ray biological irradiation instrument which uses high-energy X-rays as a source of radiation to irradiate organisms and cells to generate biological ionizing radiation. technical background [0002] Research in radiology has found that the ionizing radiation effect of rays on organisms can destroy the body's hematopoietic and immune systems. Studies have confirmed that bone marrow transplantation is the most effective method for treating acute radiation sickness in animals. Therefore, the use of ionizing radiation to damage the body's hematopoietic and immune systems has also become a means of bone marrow transplantation research. In biomedical research such as leukemia bone marrow transplantation treatment, the ionizing radiation effect of radiation is used to destroy tumor cells in the body, and then b...
