Description

Technical Field

[0001] This application relates to the field of radiation detection technology, specifically to a radiation detection protective device. Background Technology

[0002] The radiology department is an important auxiliary examination department in hospitals. In modern hospital construction, the radiology department is a department that integrates examination, diagnosis, and treatment. Many diseases in various clinical departments require examination through radiology equipment to achieve a clear diagnosis and auxiliary diagnosis. When patients undergo radiological examinations, in order to avoid damage to areas that do not need to be examined, they usually wear lead aprons on these areas. Lead aprons can minimize harm to patients by shielding them from radiation. However, using lead aprons for protection is not only cumbersome to put on and take off, but may also cause discomfort to patients. Therefore, a protective device for radiological examinations is proposed. Utility Model Content

[0003] The purpose of this application is to provide a radiation protection device to address the technical problem that using lead aprons for protection is not only cumbersome to put on and take off, but may also cause discomfort to patients.

[0004] To achieve the above objectives, this application specifically adopts the following technical solution:

[0005] A radiation protection device for radiation detection includes a fixed frame with a standing area and a driving mechanism. Two sliding rods and a sliding frame are slidably mounted on the fixed frame. The sliding rods and the sliding frame are connected or disconnected by a locking fastener. Two moving frames and a transverse frame are slidably mounted on the sliding frame. The two moving frames are staggered. A composite protective layer is provided between the sliding rods and the fixed frame, inside the moving frames and the transverse frames. The driving mechanism drives the sliding frames to slide.

[0006] Furthermore, the driving mechanism includes two rope-winding wheels and two guide wheels, each rotatably mounted on a fixed frame. A pull rope is wound on the rope-winding wheel, and the free end of the pull rope passes around the guide wheel and is connected to the sliding frame.

[0007] Furthermore, a drive rod and a worm are rotatably mounted on the fixed frame, and the rope winding wheel is connected to the drive rod via a bevel gear pair. A worm wheel that meshes with the worm is mounted on the drive rod.

[0008] Furthermore, a drive rack is slidably mounted on the fixed frame, and a fixed gear that meshes with the drive rack is mounted on the worm gear.

[0009] Furthermore, the locking element includes a protruding rod disposed on the sliding frame, a locking rod hinged to the sliding rod and a torsion spring disposed between the two, the locking rod being L-shaped and engaging with the protruding rod, and a guide slope being constructed on the locking rod.

[0010] Furthermore, the sliding frame has a first waist hole, and the moving frame is provided with a first screw that slides in cooperation with the first waist hole. The first screw is threaded with a first nut that abuts and overlaps with the sliding frame.

[0011] Furthermore, the sliding frame has a second waist hole, and the transverse frame is provided with a second screw that slides with the second waist hole. The second screw is threaded with a second nut that abuts and overlaps with the sliding frame.

[0012] Furthermore, the composite protective layer comprises a lead rubber layer, a tungsten alloy mesh layer, and a polyethylene matrix layer arranged sequentially.

[0013] The beneficial effects of this application are as follows: When using this application, the patient stands in the standing area, and by adjusting the position of multiple composite protective layers, the parts of the patient that need to be tested for radiation are exposed, while the parts that do not need to be tested are protected, thereby reducing the harm to the patient. Compared with the existing technology of wearing lead aprons for protection, there is no need to put on and take off, making it more convenient to use and without causing discomfort to the patient, thus making it more practical.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figures 1-3 As shown in one embodiment of this application, a radiation protection device for detection includes a fixed frame 1, a standing area 2 and a driving mechanism. The standing area 2 is for the patient to stand. Two sliding rods 3 and a sliding frame 4 are slidably arranged on the fixed frame 1. The sliding rods 3 are horizontal and slide vertically, and the sliding frame 4 is vertical and slides vertically. The sliding rods 3 and the sliding frame 4 are connected or disconnected by a locking fastener. Two moving frames 5 and a transverse frame 6 are slidably arranged on the sliding frame 4. The two moving frames 5 are staggered. Both the moving frames 5 and the transverse frame 6 are vertical and slide horizontally. A composite protective layer 7 is provided between the sliding rods 3 and the fixed frame 1, and inside the moving frames 5 and the transverse frame 6. The composite protective layer 7 can shield radiation. The composite protective layer 7 between the sliding rods 3 and the fixed frame 1 is a leg protective layer and can deform. The composite protective layer 7 inside the moving frames 5 is a torso or arm protective layer. The composite protective layer 7 inside the transverse frame 6 is a head protective layer. The driving mechanism drives the sliding frame 4 to slide.

[0023] In the initial state, the slide bar 3, sliding frame 4, two moving frames 5, and lateral moving frame 6 are all in their initial positions. The two moving frames 5 are close to each other, and the lateral moving frame 6 is located in the middle of the sliding frame 4. The slide bar 3 and the sliding frame 4 are in contact and connected by a locking mechanism. The leg protection layer is in a retracted state. When the patient is undergoing radiation testing, they stand in the standing area 2. When both legs of the patient need to be tested, the slide bar 3 is disconnected from the sliding frame 4 by the locking mechanism. The sliding frame 4 is then driven upward by the drive mechanism until its bottom is above the patient's legs. At this point, the patient's torso and arms are protected by two torso or arm protection layers, and the patient's head is protected by a head protection layer. Then, radiation testing can be performed on both legs. When radiation testing is required on one leg, one of the slide bars 3 is disconnected from the sliding frame 4 by the locking mechanism. The sliding frame 4 is then driven upward by the drive mechanism, causing one of the slide bars 3 to slide upward as well. The leg protection layer is then extended until its bottom is above the patient's legs. The leg protection layer protects one leg of the patient, allowing for radiation testing on that leg. When radiation testing of the patient's head is required, the driving mechanism drives the sliding frame 4 upward, causing the two sliding rods 3 to slide upward together. Both leg protection layers are in the unfolded state until the top of the sliding frame 4 is located around the patient's chin. Then, the horizontal moving frame 6 is driven to slide away from the middle position of the sliding frame 4. When radiation testing of the patient's torso is required, the driving mechanism drives the sliding frame 4 upward, causing the two sliding rods 3 to slide upward together. Both leg protection layers are in the unfolded state. The two moving frames 5 are driven to slide away from each other, exposing the patient's torso. When radiation testing of the patient's arms is required, the driving mechanism drives the sliding frame 4 upward, causing the two sliding rods 3 to slide upward together. Both leg protection layers are in the unfolded state. The two moving frames 5 are driven to slide until they overlap, exposing the patient's arms. When radiation testing of one arm is required, one of the moving frames 5 is slid to expose the patient's arm.

[0024] In summary, when using this application, the patient stands on the standing area 2, and by adjusting the position of multiple composite protective layers 7, the parts of the patient requiring radiation detection are exposed, while the parts that do not need to be detected are protected, thus reducing harm to the patient. Compared with the existing technology of wearing lead aprons for protection, it does not require putting on and taking off, is more convenient to use, and does not cause discomfort to the patient, thus being more practical.

[0025] like Figures 1-4As shown, in some embodiments, the driving mechanism includes two rope-winding wheels 8 and two guide wheels 9, each rotatably mounted on the fixed frame 1. The rope-winding wheels 8 and the guide wheels 9 are both vertical. A pull rope 10 is wound on the rope-winding wheel 8. The free end of the pull rope 10 passes around the guide wheel 9 and is connected to the sliding frame 4. The free end of the pull rope 10 is fixedly connected to the sliding frame 4.

[0026] Referring to the above, in use, the two rope-winding wheels 8 are driven to rotate synchronously in opposite directions, and the two rope-winding wheels 8 tighten the two pull ropes 10 respectively. The two pull ropes 10 are guided and limited by the two guide wheels 9 respectively. The two pull ropes 10 together pull the sliding frame 4 upward. Conversely, the two rope-winding wheels 8 are driven to rotate synchronously in opposite directions, and the two rope-winding wheels 8 loosen the two pull ropes 10 respectively. The two pull ropes 10 are guided and limited by the two guide wheels 9 respectively. The sliding frame 4 slides downward due to gravity, thus driving the sliding frame 4 to slide.

[0027] like Figures 4-5 As shown, in some embodiments, a drive rod 11 and a worm gear 12 are rotatably mounted on the fixed frame 1. Both the drive rod 11 and the worm gear 12 are in the horizontal direction. The rope winding wheel 8 and the drive rod 11 are connected by a bevel gear pair 13. The bevel gear pair 13 includes two meshing bevel gears. The two bevel gears are respectively fixed on the rope winding wheel 8 and the drive rod 11. The two bevel gear pairs 13 are symmetrically distributed. A worm wheel 14 that meshes with the worm gear 12 is mounted on the drive rod 11. The worm wheel 14 is in the vertical direction and fixed on the drive rod 11.

[0028] Referring to the above, during use, the worm gear 12 is driven to rotate, and the worm wheel 14 will rotate due to meshing, driving the drive rod 11 to rotate together. When the drive rod 11 rotates, it drives the two rope wheels 8 to rotate through the two bevel gear pairs 13 respectively. Since the two bevel gear pairs 13 are symmetrically distributed, the two rope wheels 8 rotate in opposite directions, so as to drive the two rope wheels 8 to rotate synchronously in opposite directions. Self-locking is achieved through the transmission cooperation between the worm wheel 14 and the worm gear 12.

[0029] like Figure 5 As shown, in some embodiments, a drive rack 15 is slidably disposed on the fixed frame 1, the drive rack 15 slides in the horizontal direction, and a fixed gear 16 that meshes with the drive rack 15 is disposed on the worm 12, the fixed gear 16 is in the vertical direction and fixed on the worm 12.

[0030] Referring to the above, when using it, medical staff can kick the drive rack 15 with their feet to make the drive rack 15 slide horizontally. The fixed gear 16 rotates due to the meshing action and drives the worm gear 12 to rotate together. Therefore, medical staff do not need to bend over and drive the worm gear 12 to rotate by hand, making it more convenient to use.

[0031] like Figure 2As shown, in some embodiments, the locking element includes a protruding rod 17 disposed on the sliding frame 4. The protruding rod 17 is horizontal and fixed on the sliding frame 4. A locking rod 18 is hinged to the sliding rod 3 and a torsion spring 19 is disposed between the two. The torsion spring 19 is horizontal and its two ends are fixedly connected to the sliding rod 3 and the locking rod 18 respectively. The locking rod 18 is L-shaped and abuts against the protruding rod 17. A guide slope 20 is constructed on the locking rod 18.

[0032] Referring to the above, in the initial state, the locking lever 18 is vertical and abuts against the protruding rod 17, and the torsion spring 19 is in its natural state. When the sliding frame 4 slides, it will drive the sliding rod 3 to slide together, so as to connect the sliding rod 3 with the sliding frame 4. When it is necessary to disconnect the sliding rod 3 from the sliding frame 4, the locking lever 18 is rotated to the inclined direction and away from the protruding rod 17, and the torsion spring 19 is compressed. At this time, if the sliding frame 4 slides, it will not drive the sliding rod 3 to slide together, so as to disconnect the sliding rod 3 from the sliding frame 4. Then, the locking lever 18 is released, the torsion spring 19 returns to its natural state, and the locking lever 18 rotates back to the vertical direction. When the sliding frame 4 slides down to the initial position, the protruding rod 17 first abuts against the guide slope 20, forcing the locking lever 18 to rotate to the inclined direction, and the torsion spring 19 is compressed. Then, the torsion spring 19 returns to its natural state, and the locking lever 18 rotates to the vertical direction and abuts against the protruding rod 17.

[0033] like Figure 3 As shown, in some embodiments, the sliding frame 4 is provided with a first waist hole 21, the first waist hole 21 is in the horizontal direction, the moving frame 5 is provided with a first screw 22 that slides with the first waist hole 21, the first screw 22 is in the horizontal direction and fixed on the moving frame 5, and a first nut 23 that abuts and overlaps with the sliding frame 4 is threaded on the first screw 22.

[0034] Referring to the above, in the initial state, the first nut 23 is tightened and contacts the sliding frame 4, preventing the moving frame 5 from sliding, thus locking the moving frame 5. In use, the first nut 23 can be loosened to move away from the sliding frame 4, and then the moving frame 5 can be driven to slide, causing the first screw 22 to slide within the first waist hole 21. When the sliding frame 4 slides to the desired position, the first nut 23 is tightened and contacts the sliding frame 4, thereby relocking the moving frame 5 and improving the stability of use.

[0035] like Figure 3 As shown, in some embodiments, the sliding frame 4 is provided with a second waist hole 24, the second waist hole 24 is in the horizontal direction, the transverse frame 6 is provided with a second screw 25 that slides with the second waist hole 24, the second screw 25 is in the horizontal direction and fixed on the transverse frame 6, and a second nut 26 that abuts and overlaps with the sliding frame 4 is threaded on the second screw 25.

[0036] Referring to the above, in the initial state, the second nut 26 is tightened and contacts the sliding frame 4, preventing the transverse frame 6 from sliding and thus locking the transverse frame 6. In use, the second nut 26 can be loosened to move away from the sliding frame 4, and then the transverse frame 6 can be driven to slide, causing the second screw 25 to slide within the second waist hole 24. When the transverse frame 6 slides to the desired position, the second nut 26 is tightened and contacts the sliding frame 4, thereby relocking the transverse frame 6 and further improving the stability of use.

[0037] like Figure 6 As shown, in some embodiments, the composite protective layer 7 includes a lead rubber layer 701, a tungsten alloy mesh layer 702, and a polyethylene matrix layer 703 sequentially distributed. The lead rubber layer 701 has a thickness of 3-5 mm, the tungsten alloy mesh layer 702 has a mesh size of 80-100, and the polyethylene matrix layer 703 has a thickness of 8-12 mm. The high-density lead element in the lead rubber layer 701 has a strong absorption capacity for gamma rays and neutron rays, and a thickness of 3-5 mm is sufficient to achieve basic attenuation. The high atomic number tungsten in the tungsten alloy mesh layer 702, through the photoelectric effect and... Compton scattering further shields high-energy rays. The 80-100 mesh structure reduces weight while forming a spatial scattering barrier, reducing secondary radiation. The polyethylene matrix layer 703, with its high hydrogen content, effectively slows down fast neutrons through elastic collisions. The 8-12mm thickness can reduce neutron energy to thermal neutron levels. The addition of boron enhances the capture effect. The composite protective layer 7, consisting of lead rubber layer 701, tungsten alloy mesh layer 702, and polyethylene matrix layer 703, has a lower total density than pure lead plates, which helps reduce the overall weight.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application.
