Description

Technical Field

[0001] This utility model relates to the field of pediatric radiological examination, and more specifically, to a body position adjustment and fixation device for pediatric radiological examination. Background Technology

[0002] In pediatric radiological examinations, children's large size differences and low cooperation often lead to low examination efficiency. Most existing positioning devices are difficult to adjust flexibly to accommodate the different sizes of children's heads, torsos, and legs, while some adjustable devices have complex adjustment structures and high costs. At the same time, traditional fixation methods are not comfortable enough and can easily exacerbate children's fear, further affecting the examination process.

[0003] How to invent a position adjustment and fixation device for pediatric radiological examinations to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a body position adjustment and fixation device for pediatric radiological examinations, which aims to improve the problems of existing devices being difficult to flexibly adjust to children's body size, having complex adjustment structures, and being costly.

[0005] This utility model is implemented as follows: A pediatric radiological examination positioning and fixing device includes a mounting part, which includes two opposing brackets. Two sets of vertically parallel guide rails are fixedly connected between the top ends of the two brackets. Three support parts are slidably connected on the upper guide rail, corresponding to the patient's head, torso, and legs, respectively. Three adjustment and limiting mechanisms are slidably connected on the lower guide rail. Each adjustment and limiting mechanism is fixedly connected to its corresponding support part, and each adjustment and limiting mechanism is provided with a restraint mechanism.

[0006] In a preferred embodiment of this utility model, each of the support parts includes a support plate body. Both ends of the support plate are integrally formed with connecting channels along the length direction. Each connecting channel is slidably engaged with a corresponding guide rail. The top surface of the support plate has a downwardly recessed structure, and the joints at both ends of the recessed structure are rounded.

[0007] In a preferred embodiment of this utility model, each of the adjustment and limiting mechanisms includes a main block. A connecting rod is integrally provided at both ends of the upper surface of the main block. The top end of each connecting rod is fixedly connected to the bottom surface of the corresponding support part. A receiving cavity is opened on the bottom surface of the main block. A sliding hole is opened through both ends of the main block. Both sliding holes are connected to the receiving cavity. An arc-shaped abutment limiting part is slidably connected to both ends of the receiving cavity. Both arc-shaped abutment limiting parts are connected to the synchronous adjustment mechanism.

[0008] In a preferred embodiment of this utility model, each of the arc-shaped abutment limiting parts is provided with an anti-slip protective pad on the surface of the guide rail facing the corresponding side, and each of the arc-shaped abutment limiting parts is integrally provided with a connecting slider at both ends. Each connecting slider is slidably connected in the corresponding guide groove, and the four guide grooves are respectively opened at both ends of the inner walls on both sides of the receiving cavity.

[0009] In a preferred embodiment of this utility model, the synchronous adjustment mechanism includes two racks and a gear. The two racks are located on both sides of the gear and are distributed in a mirror image. One end of each rack is fixedly connected to the surface of the corresponding arc-shaped abutment limiting part. The two racks are simultaneously meshed with the gear. The gear is fixedly sleeved on the bottom end of the rotating shaft. The rotating shaft is rotatably installed in a through hole opened in the inner wall of the top of the receiving cavity. A torsion spring structure is provided at the connection between the rotating shaft and the through hole. The top end of the rotating shaft extends to the outside of the main block and is fixedly sleeved with an adjustment knob.

[0010] In a preferred embodiment of this utility model, the constraint mechanism includes multiple sets of one-to-one corresponding mounting blocks. Each set of mounting blocks is fixedly installed at both ends of the top surface of the corresponding main block and is symmetrically distributed. One end of a constraint strap is fixedly connected to one side of the surface of one of the mounting blocks in each set. The other end of the constraint strap and one end of another mounting block are provided with a buckle structure that can cooperate with each other.

[0011] In a preferred embodiment of this invention, each of the constraint straps is made of elastic material and is provided with a length adjustment structure.

[0012] The beneficial effects of this utility model are as follows: The pediatric radiological examination positioning and fixing device obtained through the above design separates the support part from the adjustment and limiting mechanism via a double guide rail configuration in the mounting part. This ensures support stability and overall structural strength while enabling zoned sliding adjustment and rapid locking of children of different body sizes. The restraint mechanism effectively restricts child movement. The overall structure is relatively simpler, reducing equipment costs and operational difficulty, and improving the efficiency and safety of pediatric radiological examinations.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a pediatric radiological examination body position adjustment and fixation device, including a mounting part 1, the mounting part 1 including two opposing brackets 101, two sets of vertically parallel guide rails 102 fixedly connected between the top ends of the two brackets 101, three support parts 2 slidably connected on the upper guide rail 102, the three support parts 2 respectively corresponding to the patient's head, torso and legs, and three adjustment limiting mechanisms 3 slidably connected on the lower guide rail 102, each adjustment limiting mechanism 3 being fixedly connected to the corresponding support part 2, and each adjustment limiting mechanism 3 being provided with a restraint mechanism.

[0021] Please see Figure 1 and Figure 3Each support part 2 includes a support plate body. Both ends of the support plate are integrally provided with connecting holes 201 along the length direction. Each connecting hole 201 is slidably engaged with the corresponding guide rail 102. The top surface of the support plate has a downward concave structure, and the joints at both ends of the concave structure are rounded.

[0022] The support plate has connecting holes 201 at both ends, which slide in conjunction with the guide rail 102, allowing the support part 2 to slide laterally along the guide rail 102. After adjusting the position, it is locked by adjusting the limiting mechanism 3. The recessed structure is ergonomic, improving the feeling of being enveloped when lying down and enhancing the child's sense of security. The rounded corner design reduces safety hazards during the examination process, and together with the restraint mechanism, it can improve the child's cooperation and indirectly improve the efficiency of radiological examinations.

[0023] Please see Figure 3 and Figure 4 Each adjustment limiting mechanism 3 includes a main block 301. Both ends of the upper surface of the main block 301 are integrally provided with connecting rods 306. The top end of each connecting rod 306 is fixedly connected to the bottom surface of the corresponding support part 2. The bottom surface of the main block 301 is provided with a receiving cavity. Both ends of the main block 301 are provided with sliding holes 302. Both sliding holes 302 are connected to the receiving cavity. Both ends of the receiving cavity are slidably connected with arc-shaped abutment limiting parts 303. Both arc-shaped abutment limiting parts 303 are connected to the synchronous adjustment mechanism.

[0024] The main block 301 has a receiving cavity at its bottom, with sliding holes 302 passing through both ends and communicating with the receiving cavity. It is fixed to the bottom of the support part 2 by a connecting rod 306 and slides synchronously with the support part 2. Two arc-shaped abutment limiting parts 303 are slidably connected inside the receiving cavity, and their surfaces can press against both sides of the guide rail 102. The opening and closing are controlled by a synchronous adjustment mechanism. The arc-shaped structure fits against the guide rail 102, increasing the contact area and improving locking stability. Compared with the traditional bolt fixing method, the operation is more convenient, the adjustment time is reduced, and it is suitable for the need for quick positioning during child examinations.

[0025] Furthermore, each arc-shaped abutment limiting part 303 is provided with an anti-slip protective pad on the surface facing the corresponding side guide rail 102. Each arc-shaped abutment limiting part 303 is integrally provided with a connecting slider 304 at both ends. Each connecting slider 304 is slidably connected in the corresponding guide groove 305. The four guide grooves 305 are respectively opened at both ends of the inner walls on both sides of the receiving cavity.

[0026] An anti-slip pad is provided on the surface of the guide rail 102 of the arc-shaped abutment limiting part 303 to increase friction and prevent slippage after locking. The two ends of the arc-shaped abutment limiting part 303 are embedded in the guide groove 305 via connecting sliders 304, restricting its movement direction and ensuring that it slides only radially along the guide rail 102, avoiding wobbling. The anti-slip pad cooperates with the guide structure to prevent the support part 2 from shifting after locking, ensuring reliable body positioning during radiological examinations and reducing the problem of repeated examinations due to child movement.

[0027] Furthermore, the synchronous adjustment mechanism includes two racks 307 and one gear 308. The two racks 307 are located on both sides of the gear 308 and are distributed in a mirror image. One end of each rack 307 is fixedly connected to one side surface of the corresponding arc-shaped abutment limiting part 303. The two racks 307 are simultaneously meshed with the gear 308. The gear 308 is fixedly sleeved on the bottom end of the rotating shaft 309. The rotating shaft 309 is rotatably installed in the through hole opened in the inner wall of the top of the receiving cavity. A torsion spring structure is provided at the connection between the rotating shaft 309 and the through hole. The top end of the rotating shaft 309 extends to the outside of the main block 301 and is fixedly sleeved with an adjustment knob 310.

[0028] Rotating the adjustment knob 310 drives the gear 308 to rotate, causing the racks 307 on both sides to move synchronously in opposite directions. This drives the arc-shaped abutment limiting parts 303 to release the guide rail 102, thus adjusting the position of the corresponding support part 2. After adjustment, releasing the knob causes the torsion spring structure to drive the gear 308 to rotate in the opposite direction, and the two racks 307 to reset, causing the two arc-shaped abutment limiting parts 303 to abut against the guide rail 102 again. Synchronous clamping controlled by the knob is more convenient to operate than the traditional dual-sided independent adjustment structure, shortening the adjustment time, reducing the difficulty of operation for medical staff, and reducing children's anxiety while waiting.

[0029] Furthermore, the constraint mechanism includes multiple sets of corresponding mounting blocks 311. Each set of mounting blocks 311 is fixedly mounted on both ends of the top surface of the corresponding main block 301 and is symmetrically distributed. One end of a constraint band 312 is fixedly connected to one side of one mounting block 311 in each set. The other end of the constraint band 312 and one end of another mounting block 311 are provided with a snap-fit ​​structure 313 that can cooperate with each other.

[0030] Two mounting blocks 311 are symmetrically fixed at both ends of the top of the main block 301 for mounting restraint straps 312. One end of the restraint strap 312 is fixed to one side mounting block 311, and the other end is connected to the opposite side mounting block 311 via a snap-fit ​​structure 313, allowing for quick application and removal. Addressing the issue of children's fear and lack of cooperation, the restraint straps 312 can fix the limbs or torso, preventing movement from affecting examination results, reducing the number of repeated examinations, and improving efficiency. The restraint mechanism is integrated with the adjustment and limiting mechanism 3, resulting in a compact structure that is easy to disassemble and clean.

[0031] Furthermore, each constraint band 312 is made of elastic material and has a length adjustment structure.

[0032] The restraint strap 312 is made of elastic material (such as elastic band), which can stretch slightly with the child's body movements to avoid discomfort caused by excessive tightness. It features Velcro, buckles, or sliding adjustment mechanisms to adjust the length of the restraint strap 312 according to the child's body shape, ensuring effective fixation while reducing pressure. This alleviates fear caused by restraint and improves cooperation.

[0033] Working principle: In use, first adjust the position of the three support parts 2 by sliding them laterally along the upper guide rail 102 according to the shape of the child patient's head, torso, and legs. Then, rotate the gear 308 by rotating the corresponding adjustment knob 310 in sequence. This causes the racks 307 on both sides to drive the arc-shaped abutment limit part 303 to release the guide rail 102. After the position of the support part 2 is adjusted, release the knob. The torsion spring structure drives the gear 308 to rotate in the opposite direction, causing the arc-shaped abutment limit part 303 to press against the lower guide rail 102 through the anti-slip protective rubber pad and lock the support part 2. At the same time, the elastic restraint strap 312 is used to bind and fix the corresponding body parts of the child using the buckle structure 313. The concave rounded corner structure at the top of the support plate conforms to the curve of the child's body, improving comfort and safety. Ultimately, this achieves rapid adjustment of body position, stable fixation, and restraint of the child's limbs, ensuring the efficient conduct of radiological examinations.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
