Description

Technical Field

[0001] This utility model belongs to the field of radiology and relates to an adjustment frame for radiology. Background Technology

[0002] When hospitals examine and treat patients, they need to use radiation devices to irradiate the patients. During the irradiation, a mobile frame with radiation protection function is used to block the parts that do not need to be examined.

[0003] Authorization announcement number CN212186534U discloses a special radiation protection mobile frame for radiology departments, including a base plate, uprights, and a first upper crossbar. The uprights are bolted to both ends of the top of the base plate. One end of each upright has a first upper fixing groove, and the bottom of the first upper fixing groove has a first lower fixing groove. The first upper crossbar is fitted inside the first upper fixing groove, and a first main tube is bolted to both ends of the bottom of the first upper crossbar. A first lead screw is installed inside the first main tube via bearings, and a first secondary tube is fitted to the bottom of the first main tube. An upper radiation protection curtain is fitted to the outside of the first main tube. This utility model has a simple structure, is easy to operate, and allows for adjustment of both height and shielding area, making it suitable for widespread promotion and use.

[0004] However, the radiation-proof curtains in the above-mentioned solutions are mostly connected to the brackets by bolts. When the curtains are worn out and need to be replaced, or when the number of curtains needs to be increased or decreased according to different radiation intensities, the disassembly and installation process is extremely cumbersome, which seriously affects the efficiency of the department. In addition, the existing devices generally lack effective hand support structures, and patients lack stable grip support points during examinations, which not only reduces the comfort of use, but also creates a risk of falls. Furthermore, the above-mentioned solutions use a double-sided screw linkage method to adjust the protective coverage of the radiation-proof curtains. Although this achieves the change of the shielding area, its operation must rely on the simultaneous coordinated rotation of both hands, and cannot be completed with one hand, which brings great inconvenience to medical staff for quick adjustments.

[0016] like Figures 1-5 As shown, a radiology adjustment frame includes a base 1, on which a slide rail 5 is provided. The slide rail 5 is used to support the sliding of the first crossbar 31 and the slide frame 21. A hand-holding mechanism is provided on the slide rail 5 to increase the hand-holding function of the adjustment frame. The height of the hand-holding handle 22 is adjustable. A fixing mechanism is provided on the inner wall of the slide rail 5 to facilitate the adjustment of the height position of the radiation shielding curtain 6 and to facilitate the subsequent disassembly and replacement of the radiation shielding curtain 6. An extension mechanism is provided at the bottom of the fixing mechanism to extend the radiation shielding curtain 6 to increase the radiation shielding range. The radiation shielding curtain 6 is provided on the fixing mechanism to block radiation. The hand-holding mechanism includes a sliding frame 21 and a handle 22. The sliding frame 21 is slidably mounted on the slide rail 5. The sliding frame 21 is used to support the installation of the handle 22. The handle 22 is fixed to the sliding frame 21 and is used for the patient to hold on.

[0017] The slide rail 5 has a socket 23, which is a cylindrical through hole. The socket 23 is used not only to receive the insertion of the pin 25, but also to receive the insertion of the rod 32.

[0018] A first spring 24 is fixedly installed on the slide frame 21. The first spring 24 is configured to apply force to the pin 25 so that the pin 25 is inserted into the socket 23. One end of the first spring 24 is fixed to the pin 25, and one end of the pin 25 penetrates the inner wall of the slide frame 21. The pin 25 is configured to be inserted into the socket 23.

[0019] The fixing mechanism includes a first crossbar 31, a cavity 38, and a groove 35. The first crossbar 31 is slidably disposed on the inner wall of the slide rail 5. The first crossbar 31 is provided to support the opening of the cavity 38 and the groove 35. The cavity 38 is opened on the inner wall of the first crossbar 31. The cavity 38 is provided to support the sliding of the limiting block 33. The groove 35 is opened on the first crossbar 31. The groove 35 is provided to support the storage of the pull frame 36. One end of the radiation-proof curtain 6 is fixed to the first crossbar 31.

[0020] The cavity 38 is square in shape. A limit block 33 is slidably provided on the inner wall of the cavity 38. The limit block 33 is used to support the installation of the insertion rod 32. The insertion rod 32 is fixed to one end of the limit block 33. One end of the insertion rod 32 passes through the side of the first crossbar 31. The insertion rod 32 is used to be inserted into the insertion hole 23.

[0021] The other end of the limiting block 33 is provided with a pull rod 34 and a second spring 37. The pull rod 34 is provided to support the installation of the pull frame 36. One end of the second spring 37 is fixedly connected to the inner wall of the cavity 38. The second spring 37 is provided to apply force to the limiting block 33 so that one end of the limiting block 33 is tightly attached to the inner wall of the cavity 38. One end of the pull rod 34 passes through the inner wall of the groove 35 and is fixedly installed with the pull frame 36. The pull frame 36 cooperates with the pull rod 34 to pull the limiting block 33 to move.

[0022] The extension mechanism includes a second crossbar 42, a limiting rod 45, and a limiting cylinder 44. The second crossbar 42 is fixed to the other end of the radiation-proof curtain 6. The second crossbar 42 and the first crossbar 31 are used to support the installation of the radiation-proof curtain 6. The limiting cylinder 44 is fixed to the second crossbar 42, and the limiting rod 45 is fixed to the bottom end of the first crossbar 31. The bottom end of the limiting rod 45 slides on the inner wall of the limiting cylinder 44. The limiting cylinder 44 and the limiting rod 45 are used to limit the movement of the second crossbar 42, which facilitates the vertical movement of the second crossbar 42.

[0023] The second crossbar 42 has a mounting groove 49, and a shaft 410 is rotatably connected to the inner wall of the mounting groove 49. The shaft 410 is used to support the installation of the first connecting rod 43. The first connecting rod 43 is fixed on the shaft 410. The first connecting rod 43 is used to support the installation of the second connecting rod 41. The end of the first connecting rod 43 is rotatably connected to the second connecting rod 41. The bottom end of the first crossbar 31 is provided with a mounting seat 46, which is used to support the rotation of the second connecting rod 41. One end of the second connecting rod 41 is rotatably connected to the inner wall of the mounting seat 46.

[0024] A worm gear 48 is fixed on the shaft 410, and a worm 47 is rotatably connected to the inner wall of the mounting groove 49. The bottom end of the worm 47 passes through the bottom end of the second crossbar 42, and the worm 47 meshes with the worm gear 48. The arrangement of the worm gear 48 and the worm 47 means that when the worm 47 rotates, it will drive the shaft 410 to rotate through the worm gear 48.

[0025] During the use of the adjustment frame, when it is necessary to adjust the height of the radiation shielding curtain 6, pull the pull frames 36 on both sides. When the pull frames 36 move, they will drive the limit blocks 33 on both sides to slide towards each other along the inner wall of the cavity 38 through the pull rod 34. When the limit blocks 33 slide towards each other, they will squeeze the second spring 37 and simultaneously drive the insertion rod 32 to move until one end of the insertion rod 32 leaves the insertion hole 23. At this time, the fixation of the first crossbar 31 can be released. Then slide the first crossbar 31 along the inner wall of the slide rail 5 until the radiation shielding curtain 6 on the first crossbar 31 moves to a suitable height position and the insertion rod 32 corresponds to the corresponding insertion hole 23. Then release the pull frame 36. At this time, under the action of the second spring 37, the insertion rod 32 will be inserted into the corresponding insertion hole 23, thereby fixing the first crossbar 31. With the above settings, it is convenient to adjust the height of the radiation shielding curtain 6, and the radiation shielding curtain 6 can be disassembled and replaced as needed. At the same time, the number of radiation shielding curtains 6 can be flexibly increased or decreased according to actual protection needs.

[0026] When it is necessary to extend the range of the radiation shielding curtain 6, the worm gear 47 can be rotated, which drives the worm wheel 48 to rotate. When the worm wheel 48 rotates, it will drive the first connecting rod 43 to deflect through the shaft 410. When the first connecting rod 43 deflects, it will drive the first crossbar 31 to move through the second connecting rod 41 and the mounting base 46. Since the position of the first crossbar 31 is fixed and it is limited by the limiting rod 45 and the limiting cylinder 44, the second crossbar 42 will move vertically. In conjunction with the first crossbar 31, the purpose of stretching the radiation shielding curtain 6 can be achieved, which is beneficial to improving the radiation shielding range.

[0027] Furthermore, it is equipped with a handle 22 to provide hand support for patients, and the height of the handle 22 can be adjusted via the pin 25 and the socket 23.

[0028] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
