[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1

[0034] See also Figures 1 to 10 The present invention provides a technical solution: a radiation protection device for medical radiation diagnosis and treatment, comprising: a bed 11, a diagnosis frame 12 is arranged on the top of the bed 11, a telescopic rod 13 is arranged on the side of the diagnosis frame 12, and a socket 14 is inserted at the bottom of the telescopic rod 13, and a radiation inspection piece 15 is fixed at the bottom of the socket 14;

When the socket 14 moves vertically, the pressing block 21 presses against the surface of the gear switch 22 at different gears to realize the distance monitoring of the height of the socket 14. A distance sensor 9 is fixed on one side of the top of the bed body 11 close to the diagnosis frame 12. The distance sensor 9 monitors the distance between the distance sensor 9 and the patient's head to judge the patient's height;

[0036] The shielding component 3 is arranged on both sides of the socket 14. The shielding component 3 includes shielding lead plates 31 arranged on both sides of the radiological inspection piece 15. The control component 4 is controlled to work according to the height signal monitored by the socket 14, and the deployment angle of the shielding lead plates 31 is adjusted by the control component 4.

[0037] The shielding component 25 is arranged on both sides of the bed body 11. The shielding component 25 includes shielding lead plates 251 arranged on both sides of the bed body 11. The control component 26 works according to the height signal monitored by the socket 14, and the deployment angle of the shielding lead plates 251 is adjusted by the control component 26;

[0038] The expansion angles of the shielding lead plate 1 31 and the shielding lead plate 2 51 are adjusted according to the descending position of the socket 14, and the expansion angle of the shielding lead plate 1 31 is adjusted according to the height of the patient. The shielding range is adjusted by adjusting the expansion angles of the shielding lead plate 1 31 and the shielding lead plate 2 51 to reduce the area of ​​radiation exposure. When a local part of the patient needs to be tested, the radiological inspection piece 15 is controlled to move downward. When the whole body of the patient needs to be tested, the radiological inspection piece 15 is controlled to move upward to increase the detection range. When the radiological inspection piece 15 moves vertically, the socket 14 is driven to move vertically synchronously. When the socket 14 moves vertically, the pressing block 21 presses the different gears on the surface of the gear switch 22. The operation of the control component 1 4 and the control component 2 6 is controlled according to different gear signals, and the expansion angles of the shielding lead plate 1 31 and the shielding lead plate 2 51 are adjusted. Opening angle, when the patient climbs onto the bed 11, doctors generally recommend that the patient lie in the middle of the surface of the bed 11 to facilitate the radiation detection of the radiation inspection piece 15. The distance between the patient's head and feet and the two ends of the bed 11 is close. When the distance sensor 9 detects that the distance to the patient's head is long, it is judged that the patient is short. At this time, the control component 14 is controlled to make the two sets of shielding lead plates 131 close to each other, increasing the shielding range of the shielding lead plate 131. Through the above design, the shielding range of the shielding lead plate 131 and the shielding lead plate 251 is adjusted, so that the shielding range of the shielding lead plate 131 and the shielding lead plate 251 is adapted to the actual detection of the patient, so that the parts that do not need to be exposed are blocked, the area of ​​radiation exposure is reduced, the radiation impact of the surrounding environment is reduced, and the protection effect is improved.

[0039] The top of the shielding lead plate 31 is fixed to the outer wall of the rotating rod 32, the middle end of the rotating rod 32 is rotatably connected to the fixing plate 33, the fixing plate 33 is fixed to the surface of the socket 14, the two ends of the rotating rod 32 are rotatably connected to the connecting plate 34, the middle end of the connecting plate 34 is fixed to the socket 14, the fixing plate 33 supports and limits the middle end of the rotating rod 32, and the connecting plate 34 limits the end surface of the rotating rod 32, so that the rotation of the rotating rod 32 is more stable, and the rotation of the rotating rod 32 drives the shielding lead plate 31 to rotate synchronously, and the radiation of the radiological examination object 15 is blocked by two groups of shielding lead plates 31, and the shielding degree of the radiation is adjusted according to the expansion degree of the shielding lead plates 31, so that the range of the radiation is adapted to the patient.

[0040] The control component 4 includes a gear 41 fixed to the outer wall of the rotating rod 32, and a moving frame 42 is arranged on the top of the gear 41, and a rack plate 43 cooperating with the gear 41 is fixed on the bottom of the moving frame 42. The movement of the moving frame 42 drives the rack plate 43 to move synchronously. When the rack plate 43 moves, it drives the gear 41 to rotate, and the gear 41 drives the rotating rod 32 to rotate synchronously, which is convenient for driving the rotating rod 32 to rotate, thereby realizing the adjustment of the rotation angle of the shielding lead plate 31.

[0041] A moving seat 44 is fixed on the top of the moving frame 42, and a screw 45 is connected to the internal thread of the moving seat 44, one end of the screw 45 is fixedly connected to the output shaft of the motor 46, a fixing frame 47 is fixed to the outer wall of the motor 46, and the side of the fixing frame 47 is fixed to the surface of the socket 14. When the distance sensor 9 detects that the patient's height is too low, the motor 46 is controlled to rotate forward once, the motor 46 drives the screw 45 to rotate, and the rotation of the screw 45 drives the moving seat 44 to move away from the motor 46. The moving seat 44 drives the rack plate 43 to move synchronously through the moving frame 42, and the movement of the rack plate 43 drives the gear 41 to rotate clockwise, and the gear 41 By rotating the shielding lead plate 31 clockwise through the rotating rod 32, the two groups of shielding lead plates 31 are close to each other, so that the shielding lead plate 31 increases the shielding of the radiation of the radiological examination object 15. When it is necessary to detect the layout of the patient, the socket 14 is controlled to move down, the gear position at the lower end of the gear switch 22 is pressed, and the motor 46 is controlled to rotate forward once again to increase the shielding range of the shielding lead plate 31 again. When the patient's radiological examination is completed and the shielding lead plate 31 needs to be reset, the motor 46 is controlled to reverse to reset the position of the shielding lead plate 31. Through the above design, the parts of the patient that do not need to be examined by the shielding lead plate 31 are shielded by the shielding lead plate 31, thereby reducing radiation exposure.

[0042] The other end of the screw rod 45 is rotatably connected to the connecting plate 48. Limit rods 49 are fixed on both sides of the connecting plate 48, and the end faces of the limit rods 49 are fixed on the surface of the motor 46. When the screw rod 45 rotates, the movement of the moving seat 44 is limited by two sets of limit rods 49 to prevent the moving seat 44 from rotating synchronously with the screw rod 45, so that the lateral movement of the moving seat 44 is more stable.

[0043] A movable frame 52 is fixed to the surface of the shielding lead plate 51, and the bottom of the movable frame 52 is fixed to the outer wall of the rotating rod 56.

The movable frame 52 is driven to rotate synchronously according to the rotation of the rotating rod 56, and the rotation of the movable frame 52 drives the shielding lead plate 51 to rotate synchronously. By rotating the shielding lead plate 51, the range of the patient's body shielded by the shielding lead plate 51 is changed, and local parts that do not need radiation, such as arms, are shielded and protected to reduce radiation exposure.

[0044] A gear 2 55 is fixed to the outer wall of the rotating rod 2 56, and a belt 53 is meshed on the outer wall of the gear 2 55. A connecting belt 54 is fixed to one end of the belt 53, and the end face of the connecting belt 54 is fixed to the surface of the push plate 57. A pushing wheel 58 is inserted inside the push plate 57. When the shielding lead plate 2 51 needs to be reset, the pushing wheel 58 is pushed, and the pushing wheel 58 moves up to push the push plate 57 to move synchronously. The push plate 57 pulls the belt 53 to move through the connecting belt 54, and the belt 53 moves on the surface of the gear 2 55. When the belt 53 moves, it drives the gear 2 55 to rotate, and the gear 2 55 drives the rotating rod 2 56 to rotate synchronously, and the rotating rod 2 56 drives the movable frame 52 to rotate synchronously, so as to adjust the unfolding angle of the shielding lead plate 2 51.

[0045] The driving wheel 58 is set to be annular, and a limit seat 59 is provided on the side of the outer wall of the belt 53 close to the connecting belt 54, and the two ends of the limit seat 59 are fixed to the inner wall of the protective cover 81.

[0046] Embodiment 2

When the patient is subjected to a whole-body radiological examination, the socket 14 moves up, the gear position on the upper end of the gear switch 22 is pressed, and the distance between the two sets of shielding lead plates 2 51 needs to be increased, and the electric The operation of machine 2 66 drives screw 2 64 to rotate forward synchronously, and the forward rotation of screw 2 64 drives moving seat 2 63 to move upward, and moving seat 2 63 pushes support frame 61 to move upward synchronously through connecting plate 3 62, and support frame 61 drives pushing wheel 58 to move upward synchronously, and pushing wheel 58 pushes push plate 57 upward, and push plate 57 moves through connecting belt 54, belt 53, gear 2 55 and rotating rod 2 56 to drive movable frame 52 to unfold, and the distance between two sets of shielding lead plates 2 51 increases, and the shielding range of shielding lead plates 2 51 to the patient is reduced, so that the radiological examination piece 15 can perform radiological examination on the whole body of the patient.

The end face of the insertion rod 73 is fixed with a spring 74, and the end face of the spring 74 is fixed to the inner wall of the insertion cavity 72. Limit plates 82 are fixed on both sides of the surface of the insertion tube 71, and the inner wall of the limit plate 82 is in contact with the surface of the push plate 57. When a local inspection is required, the socket 14 moves downward, the gear position at the lower end of the gear switch 22 is pressed, the control motor 2 66 is reversed, the screw 2 64 reverses to drive the moving seat 2 63 to move downward, the moving seat 2 63 drives the driving wheel 58 to move downward through the connecting plate 3 62, and the driving wheel 58, the pressing force of the push plate 57 gradually decreases, and the spring 74 pulls the insertion rod 73 to move back to the inside of the insertion tube 71. The spring 74 gradually recovers from the stretched state to the normal state, and the insertion rod 73 pulls one end of the belt 53 toward the insertion tube 71, so that the belt 53 fits tightly against the surface of the gear 2 55. When the shielding lead plate 2 51 and the bed body 11 are close to a vertical state, the smaller the stretching degree of the spring 74, the smaller the indirect limiting force on the shielding lead plate 2 51. When the shielding lead plate 2 51 is closer to the bed body 11, the greater the stretching degree of the spring 74, the greater the indirect limiting force on the shielding lead plate 2 51, thereby increasing the stability of the shielding lead plate 2 51.
