Description

Technical Field

[0001] The invention relates to the technical field of radiation protection, and in particular to a medical radiation protection screen. Background Art

[0002] Radiation protection screens, also known as radiation shields, are barriers made of high-density materials (such as lead, steel, etc.) to absorb and block radiation energy and reduce the harm of radiation to personnel and the environment. In the medical field, radiation protection screens are often used in X-ray examination rooms, CT rooms, DR rooms, and operating rooms to provide necessary protection for medical staff and patients.

[0066] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0068] like Figures 1 to 6As shown, a medical radiation protection screen comprises a protective metal frame 1; a lifting frame 2, which is slidably mounted on the inner wall of the protective metal frame 1; a crossbeam 3, which is fixedly mounted on the inner wall of the lifting frame 2; a protective glass plate 4, which is fixedly mounted between the top surface of the crossbeam 3 and the inner top wall of the lifting frame 2; two protective glass frames 5, which are symmetrically fixedly mounted between the bottom surface of the crossbeam 3 and the inner bottom wall of the lifting frame 2; an adjustment mechanism, which is arranged between the two protective glass frames 5; an operation port 7, which is provided on the adjustment mechanism; an inner cavity 8, which is provided on the adjustment mechanism, and the inner cavity 8 is coaxially arranged with the operation port 7; and a sealing mechanism, which is arranged in the inner cavity 8 inside; a limit mechanism, arranged at the side position of the operation port 7; a guide port 11, opened at the side of the protective metal frame 1; a lifting mechanism, arranged on the lifting frame 2 and the protective metal frame 1; four legs 13, respectively fixedly mounted at the four corners of the bottom end of the protective metal frame 1; four moving wheels 14, respectively fixedly mounted on the bottom surfaces of the four legs 13, a display hanger 15 is arranged at the top side position of the lifting frame 2, an ultrasonic hanger 16 is arranged on the side of the protective glass frame 5, a support frame 17 is fixedly mounted on the side of the protective metal frame 1, and a hand support plate 18 is arranged at the movable end of the support frame 17;

[0069] In the initial state, the lifting frame 2 is stored in the protective metal frame 1, which occupies less space and is easy to place. When it is needed, the protective screen can be pushed to the use position through the legs 13 and the moving wheels 14, and then the lifting frame 2 can be driven by the lifting mechanism so that the lifting frame 2 moves out of the protective metal frame 1 for use. The ultrasound doctor can pass the operating arm through the operation port 7, and then operate the sealing mechanism through the limiting mechanism so that the operating arm of the ultrasound doctor can be sealed in the operation port 7 to prevent the radiation from passing through the operation port 7. When in use, the position of the operation port 7 can be adjusted by the adjustment mechanism for the ultrasound doctor to use it. The arm of the ultrasound doctor passing through the operation port 7 can be supported by the support frame 17 and the hand support plate 18 for long-term work. At the same time, the display can be hung on the display bracket 15 for easy viewing. The ultrasound bracket 16 is detachably arranged on the side of the protective glass frame 5. It can be directly installed on the side of the protective glass frame 5 when in use and can be directly removed when stored. This is an existing mature technology and will not be described in detail here. The ultrasound probe used for detection can be hung on the ultrasound bracket 16 for easy access.

[0070] like Figure 3 , Figure 4As shown, the adjustment mechanism includes: a slide plate 61, which is slidably mounted on the bottom surface of the crossbeam 3, and the two ends of the slide plate 61 are located on the inner side of the two protective glass frames 5; a connecting groove 62, which is provided on the bottom surface of the slide plate 61; a connecting frame 63, which is slidably mounted on the inner side wall of the connecting groove 62; an adjusting glass plate 64, which is fixedly mounted on the bottom surface of the connecting frame 63, and the operating port 7 and the inner cavity 8 are both arranged on the adjusting glass plate 64, and a protective curtain 19 corresponding to the operating port 7 is slidably mounted on the side surface of the adjusting glass plate 64; two springs 65, which are symmetrically fixedly mounted between the top surface of the adjusting glass plate 64 and the bottom surface of the slide plate 61; a friction plate 66, which is fixedly mounted on the bottom surface of the adjusting glass plate 64;

[0071] When adjusting the position of the operating port 7, the adjusting glass plate 64 can be pushed upward to make the connecting frame 63 slide in the connecting groove 62. At this time, the friction plate 66 on the bottom surface of the adjusting glass plate 64 is separated from the inner bottom wall of the lifting frame 2, and the slide plate 61 can be pushed to make it slide in the protective glass frame 5 to adjust the position of the operating port 7. After the adjustment is completed, the adjusting glass plate 64 can be loosened. Under the action of the spring 65, the friction plate 66 can fit tightly with the inner bottom wall of the lifting frame 2 to increase the friction so as to fix the slide plate 61 and the adjusting glass plate 64 for stable use.

[0072] like Figure 4 As shown, the sealing mechanism includes: a swivel 91, rotatably mounted on the inner wall of the inner cavity 8; four arc-shaped grooves 92, which are distributed in a ring array and opened on the side of the swivel 91; four guide rods 93, which are respectively slidably mounted on the inner walls of the four arc-shaped grooves 92; four connecting blocks 94, which are respectively fixedly mounted on one end of the four guide rods 93 located on the outside of the arc-shaped grooves 92; four adjusting rods 95, which are respectively fixedly mounted on the sides of the four connecting blocks 94, and one end of the adjusting rod 95 away from the connecting block 94 passes through the inner cavity 8 and is located on the inner side of the operation port 7; four pressing plates 96, which are respectively fixedly mounted on one end of the four adjusting rods 95 located on the inner side of the operation port 7, and the pressing plates 96 are made of elastic material, and the outer wall of the pressing plates 96 is provided with skin-feeling material; two pleated protective ring cloths 97, which are symmetrically fixedly mounted between the outer walls of the four pressing plates 96 and the inner wall of the operation port 7;

[0073] Before the ultrasound doctor's operating arm passes through the operating port 7, the protective curtain 19 corresponding to the operating port 7 can be pulled open to expose the operating port 7. Then the ultrasound doctor passes the operating arm through the operating port 7 and drives the rotating ring 91 to rotate through the limiting mechanism. When the rotating ring 91 rotates, the arc groove 92 on it can rotate with the rotating ring 91, and the connecting block 94 is slidably connected to the arc groove 92 through the guide rod 93, and the adjusting rod 95 on the connecting block 94 passes through the inner cavity 8. Therefore, when the arc groove 92 rotates, the connecting block 94 and the adjusting rod 95 can be driven to slide through the guide rod 93. The four pressure plates 96 can be moved synchronously to achieve synchronous adjustment, so that the pressure plates 96 can fit the arms of the ultrasound doctor, and the skin-feeling material on the outer wall of the pressure plates 96 ensures the comfort of the pressure plates 96 when in contact with the arms. When the pressure plates 96 are adjusted, the pleated protective ring cloth 97 between the pressure plates 96 and the operating port 7 can be retracted to fill the gap between the pressure plates 96 and the operating port 7 to prevent radiation from passing through. The setting of the sealing mechanism avoids the pressure on the arms of the ultrasound doctor caused by the curtain, making the ultrasound doctor's operation easier.

[0074] like Figure 3 , Figure 5 As shown, the limiting mechanism includes: a limiting opening 101, which is opened on the side of the adjustment glass plate 64, and the limiting opening 101 is connected to the inner cavity 8; a plurality of groups of limiting blocks 102, which are distributed in a ring array and fixedly installed on the inner side wall of the limiting opening 101; a pull rod 103, which is fixedly installed on the side of the rotating ring 91, and the end of the pull rod 103 away from the rotating ring 91 extends to the outside of the limiting opening 101; a plurality of limiting grooves 104, which are opened at the opposite end of the plurality of limiting blocks 102, and the limiting grooves 104 are adapted to the pull rod 103;

[0075] When driving the swivel 91, the pull rod 103 can be pulled to slide along the limit opening 101, which can drive the swivel 91 to rotate. During the sliding process, the pull rod 103 can contact the limit grooves 104 at the ends of the limit blocks 102 one by one, and when the rotation stops, the limit grooves 104 can limit the pull rod 103, so that the angle of the swivel 91 can be fixed.

[0076] like Figure 1 , Figure 6As shown, the lifting mechanism includes: a support plate 121, which is fixedly mounted on the bottom end of the lifting frame 2, and the support plate 121 is located on the inner side of the guide opening 11; a movable pulley 122, which is rotatably mounted on the top surface of the support plate 121; a fixed pulley 123, which is rotatably mounted on the side of the protective metal frame 1 through a bracket and is located directly above the guide opening 11; a winding roller 124, which is rotatably mounted on the side of the protective metal frame 1; a winding motor 125, which is arranged on the side of the protective metal frame 1 through a fixed frame, and the output end of the winding motor 125 is fixedly connected to the winding roller 124; a cable 126, which is fixedly mounted on the bracket, and the end of the cable 126 away from the bracket sequentially passes around the movable pulley 122, the fixed pulley 123 and is fixedly connected to the winding roller 124;

[0077] When the lifting frame 2 is lifted in the vertical direction, first, the winding motor 125 is started, and this key power source starts to work, driving the winding roller 124 to rotate clockwise or counterclockwise, thereby performing the winding or unwinding action. In this process, the movable pulley 122, the fixed pulley 123 and the cable 126 together constitute an efficient pulley group system, which greatly optimizes the power transmission path, so that the force required by the winding roller 124 when winding and releasing the cable 126 is significantly reduced, achieving a labor-saving effect. As the cable 126 is tightly wound around the winding roller 124 or gradually loosened, the other end of the cable 126 is guided by the movable pulley 122 and the fixed guide of the fixed pulley 123 to form a A stable and balanced traction path is formed, which ensures that the cable 126 will not deviate from the predetermined track when transmitting force. At the same time, the force efficiency of the system is further enhanced through the multiplication effect of the movable pulley 122. The retraction and extension of the cable 126 directly drives the movable pulley 122 connected thereto and the support plate 121 arranged under the movable pulley 122 to move up and down. The support plate 121 serves as a direct supporting structure of the lifting frame 2, and its up and down sliding is directly converted into the lifting action of the lifting frame 2. During the whole process, the lifting frame 2 slides smoothly along the pre-set guide port 11. The guide port 11 not only provides the necessary motion trajectory restriction for the lifting frame 2, but also ensures the stability and accuracy during the lifting process.
