The invention discloses an internet-based
ray protection device and method for
medical radiation diagnosis and treatment. The device comprises a
workbench, wherein a rectangular through hole and a receding groove are formed in the
workbench, a rotating shaft is transversely and rotationally connected in the rectangular through hole, the outer wall of the rotating shaft is fixedly sleeved with a diagnosis and treatment
bed, two symmetrical first sliding rails are fixedly connected to the top of the
workbench, and first sliding blocks are slidably connected to the tops of the two first sliding rails. The device is simple in structure, a rotating motor is started to drive a rotating
lead plate to rotate, then the rotating
lead plate can be stored, the rotating
lead plate is prevented from occupying the space, the rotating lead plate is prevented from being frequently carried, and a patient can be diagnosed and treated at any time; and by starting a stepping motor, the diagnosis and treatment
bed can be rotated, the rotating lead plate can slide towards the inner side, and diagnosis and treatment personnel can conveniently diagnose and treat the patient at the optimal position in the later period.
