Embodiment 1

[0027] refer to Figure 1-4 As shown, an installation device for a hospital neutron irradiator includes a neutron irradiator 1, an irradiation port 2, a shielding cylinder 3, a base 4, and a base 5. The lower end surface of the base 4 is provided with a groove body 6, and the base 5 The upper end surface array of the upper surface of the upper surface of the upper end of each groove is provided with a limited groove 7, and the upper inner wall of each groove body 6 is rotatably connected with a screw rod 8, the lower end of the screw rod 8 is threaded with a threaded cylinder 10, and the upper end of the threaded cylinder 10 is fixedly sleeved with a slide plate 9, The lower end surface of the slide plate 9 is fixedly connected with the limit platform 11, the lower end surface array of the slide plate 9 is rotatably connected with a clamping plate 12, the lower end surface of the base 4 is provided with a chute 13, and the upper end surface of the base 5 is provided with a circ...

Embodiment 2

[0029] refer to Figure 1-4As shown, in the case that other parts are the same as in Embodiment 1, the difference between this embodiment and Embodiment 1 is that the base 4 is fixedly connected to the lower end surface of the neutron irradiator 1, and the horizontal section of the base 4 and the base 5 The length and width are equal in size, each groove body 6 and the limit groove 7 are arranged in an array corresponding to each other, and the upper end of the screw rod 8 that is rotated and sleeved in each groove body 6 passes through the upper inner wall of the groove body 6 and extends on the base 4 Above the upper end surface of the slide plate 9, the threaded barrel 10 extends below the slide plate 9, and the slide plate 9 is slidably arranged in the groove body 6, and the limit table 11 is fixedly connected to the lower end face of the slide plate 9 and fixedly sleeved on the outer surface of the threaded barrel 10. , the outer surface of the limiting platform 11 is inc...

Abstract

The invention discloses an installation device for a hospital neutron irradiator, relates to the field of neutron irradiators, and provides the following scheme aiming at the problems that the tail end of the existing hospital neutron irradiator is inconvenient to stably install and a covering opening is inconvenient to shield and prevent dust: the installation device comprises a neutron irradiator, an irradiation opening, a shielding cylinder, a base and a pedestal, a groove body is formed in the lower end face of the base, a limiting groove is formed in the upper end face of the base, a screw rod is rotationally connected to the upper inner wall of the groove body, the lower end of the screw rod is sleeved with a threaded cylinder and a sliding plate in a threaded mode, and the lower end face of the sliding plate is fixedly connected with a limiting table and rotationally connected with clamping plates in an array mode. AA sliding groove and a circular groove are provided with a thread fastening mechanism, and a clamping mechanism is arranged between the irradiation opening and the shielding cylinder. The installation device has the characteristics that the irradiation port can be conveniently shielded and prevented from dust, and meanwhile, the irradiation tail end of the neutron irradiator can be conveniently, efficiently, accurately and stably mounted.

Description

technical field [0001] The invention relates to the field of neutron irradiators, in particular to an installation device for hospital neutron irradiators. Background technique [0002] In 1936, G.L. Locher proposed the idea of ​​boron neutron capture therapy (BNCT). In 1951, William.H.Sweet et al first applied BNCT in the treatment of glioma. Due to the conditions at that time, the treatment was not successful. In the late 1960s, Japanese scholar H.Hatamaka became very interested in BNCT after studying at Massachusetts General Hospital of Harvard University. After returning to China, he and Sweet still insisted on researching and improving this technology. A boron-containing drug that is specifically absorbed and concentrated by tumors has been found. Improved neutron beam quality. After half a century of exploration and practice, the standard technology of thermal neutron capture therapy was finally established in Japan. After treatment for stage III and IV gliomas, ...
