Description

Technical Field

[0001] The present invention belongs to the technical field of image examination auxiliary devices, and in particular relates to an infant auxiliary device for X-ray image examination. Background Art

[0002] In modern medical diagnosis, CT imaging has become an important tool for diagnosing infant and child diseases due to its high resolution and ability to clearly display the body's internal structures. However, due to their physiological and psychological characteristics, infants and young children often have difficulty cooperating during CT imaging, which brings many difficulties to the examination process. During CT scans, infants and young children may cry and move around due to fear or discomfort. This not only blurs the image and affects the accuracy of the diagnosis, but also increases the radiation exposure of infants and young children due to prolonged examination time. In addition, traditional CT examination auxiliary devices have problems such as unstable fixation and poor comfort when fixing the infant's position, and cannot meet the special needs of infants and young children during CT examinations. In existing technologies, the head support structure of conventional assistive devices is relatively fixed and cannot be flexibly adjusted to suit individual infant head shapes and different examination requirements. This makes it difficult for infants and young children to maintain an optimal and stable head position during examinations, affecting the accuracy of CT scans. Furthermore, most existing leg straps only provide a simple fixation function. For infants and young children of varying lengths and body shapes, or when performing CT scans on different joints or limbs, it is difficult to accurately secure the legs in the ideal position to meet scanning requirements. Therefore, in order to solve the above-mentioned problems in the prior art, the present invention proposes an auxiliary device for infants and young children for X-ray imaging examination. Summary of the Invention

[0003] To solve the above-mentioned problems in the prior art, the present invention designs an infant assistance device for X-ray imaging examinations. By providing a rotatable rotating base plate at the upper end of the examination bed and a head base plate rotatably provided at the front end of the rotating base plate, the patient's position can be flexibly adjusted according to the examination site. At the same time, leg sliders are symmetrically provided on both sides of the rear end of the rotating base plate. By adjusting the front and rear positions of the leg sliders on the rotating base plate and adjusting the left and right positions of the telescopic plates on the leg sliders, the device can be flexibly adjusted according to the patient's position and body size. In order to achieve the above technical effects, the present invention is implemented through the following technical solutions: an infant auxiliary device for X-ray imaging examination, comprising: an examination bed, a rotating base plate; A rotating base plate is provided at the upper end of the examination bed; The front end of the rotating base plate is provided with a head base plate, and leg slide grooves are symmetrically provided on both sides of the rear end for sliding connection with the leg sliders, and a head rotating shaft is provided in the middle for rotatably connecting with the rotating rod; the middle of the rotating rod is fixedly connected with the head plate, and one end is provided with a plurality of limit columns arranged in an array; the upper end of the leg slider is provided with a telescopic slide groove for sliding connection with the telescopic plate; the front end of the telescopic plate is provided with a leg rotating shaft for rotatably connecting with the leg base plate; the lower end of the rotating shaft is provided with a plurality of fixed teeth in an array; a hole is provided in the middle of the lower end of the leg base plate for setting a spring for fixed connection with the rotating shaft, and a plurality of movable teeth are arranged in an array below the hole for movably connecting with the fixed teeth; Furthermore, a limiting rod movably connected to the limiting column is provided on one side of the rotating base plate; Furthermore, the limiting column is slidably connected to the rotating rod and can be extended and retracted on the rotating rod; Furthermore, fixed slides are symmetrically arranged on both sides of the head plate to be slidably connected to the waist slider, an adjusting screw is arranged in the middle, and hand fixing belts are symmetrically arranged on both sides of the front end; the two ends of the adjusting screw are respectively threadedly connected to the waist sliders on both sides; a waist fixing plate is arranged on the upper end of the waist slider; Furthermore, the thread pitch of the middle portion of the waist slider is the same, and the thread rotation direction is opposite; Furthermore, the front end of the leg slider and the upper end of the telescopic slide are respectively threadedly connected to a fixing screw; a fixing knob is provided at the front end of the fixing screw; Furthermore, a base is provided at the bottom of the examination bed, a circular groove is provided in the middle for rotationally connecting to a worm gear, and a hole is provided on one side for rotationally connecting to a worm; the worm gear meshes with the worm gear; Furthermore, the leg bottom plate is L-shaped, with one side of the upper end fixedly connected to the leg fixing belt, and the other side having a groove for slidingly connecting the other end of the fixing belt; Furthermore, the hand fixing strap structure is consistent with the leg bottom plate structure and can be rotated on the head plate; Furthermore, the upper end of the examination bed is detachably connected to a clamping plate; a hole is provided in the middle of the clamping plate for rotatably connecting to a worm gear, and a hole is provided on one side for threaded connection to a clamping screw.

[0004] The beneficial effects of the present invention are: The present invention uses a worm gear mechanism to achieve free rotation of the rotating base plate, allowing coronal and sagittal scans and other multi-directional scans to be completed without manually moving the infant, thus avoiding delays in examinations and operational errors caused by repeated adjustments to the body position. The head support plate, through the cooperation of a retractable limit column and a limit rod, can dynamically adjust the support angle and achieve multi-level locking according to the differences in infants' head shapes and the requirements of different scanning areas such as the skull and neck, ensuring precise alignment of the scanning plane with the target area and effectively reducing artifacts or missed scans caused by improper head posture. At the same time, the leg slider that slides back and forth in the leg fixing structure and the telescopic plate that extends left and right, combined with the angle rotation function of the L-shaped leg base, can fix the lower limbs in any anatomical position, such as extension, slight flexion, and abduction, to meet the scanning requirements of leg length, leg spacing, and joints such as hip and knee joints of infants of different body sizes, such as premature and full-term infants. This solves the problem that traditional one-way restraints cannot adapt to complex scanning angles, significantly improving the clarity of limb images and diagnostic reliability. Finally, the waist fixation plate achieves symmetrical and synchronous movement through reverse threaded adjustment screws, which can quickly adapt to infants and young children with different waist circumferences, avoiding the risk of displacement or skin compression damage caused by traditional restraints due to loose or tight fixation. The hand fixation belt adopts the same rotatable design as the leg base plate and is locked by the engagement of the spring and the fixed teeth; it can adapt to a variety of different body position examinations.

[0008] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0009] Example 1 like Figure 1-10 As shown, the upper end of the examination bed 2 is rotatably connected to the rotating base plate 4; The front end of the rotating base plate 4 is provided with a head base plate 6, and the rear end is symmetrically provided with leg slide grooves 5 on both sides for sliding connection with the leg sliders 16, and a head shaft 7 is provided in the middle to be rotatably connected to the rotating rod 10; the middle of the rotating rod 10 is fixedly connected to the head plate 9, and one end is provided with a plurality of limit columns 11 arranged in an array; the upper end of the leg slider 16 is provided with a telescopic slide groove 19 to be slidably connected to the telescopic plate 20; the front end of the telescopic plate 20 is provided with a leg shaft 21 to be rotatably connected to the leg base plate 23; the lower end of the shaft is provided with a plurality of fixed teeth 22 in an array; the middle of the lower end of the leg base plate 23 is provided with a hole to set a spring 26 to be fixedly connected to the rotating shaft, and the lower end of the hole is provided with a plurality of movable teeth 27 in an array to be movably connected to the fixed teeth 22; By rotating the worm 25 to drive the worm gear 3, the rotating base plate 4 fixedly connected to the worm gear 3 rotates on the upper end of the examination bed 2. This allows switching between coronal and sagittal scanning positions without moving the infant, thus solving the operational errors and infant stress problems caused by the traditional device's reliance on manual handling. Furthermore, a limiting rod 8 is provided on one side of the rotating base plate 4 and is movably connected to a limiting column 11; Furthermore, the limiting post 11 is slidably connected to the rotating rod 10 and can be extended and retracted on the rotating rod 10; The rotating rod 10 is connected to the middle part of the rotating base plate 4 through the head rotating shaft 7. The limit column 11 at the end can be extended and retracted within the rotating rod 10. When adjusting, the limit column 11 is pulled to extend out of the rotating rod 10, and the head base plate 6 is rotated to the target angle simultaneously. After releasing the limit column 11, it retracts under the action of the spring 26 and snaps into the slot of the limit rod 8 on the side of the rotating base plate 4, realizing multi-level locking of the head support angle, ensuring that the scanning layer is accurately aligned with the target area; Furthermore, fixed grooves 12 are symmetrically provided on both sides of the head plate 9 for sliding connection with the waist slider 29, an adjusting screw 13 is provided in the middle, and hand fixing straps 15 are symmetrically provided on both sides of the front end; the ends of the adjusting screw 13 are respectively threadedly connected to the waist sliders 29 on both sides; a waist fixing plate 28 is provided on the upper end of the waist slider 29; Furthermore, the thread pitch of the middle portion of the waist slider 29 is the same, and the thread rotation direction is opposite; When the adjustment knob 14 is rotated, the waist sliders 29 on both sides move synchronously and symmetrically due to the opposite rotation directions of the threads, driving the waist fixing plates 28 to adjust the spacing, closely fitting the waist circumference of the infant and restricting the twisting of the torso; Furthermore, the front end of the leg slider 16 and the upper end of the telescopic slide 19 are respectively threadedly connected to a fixing screw 17; the front end of the fixing screw 17 is provided with a fixing knob 18; The leg slider 16 slides back and forth along the leg chute 5 at the rear end of the rotating base plate 4. The medical staff manually pushes the slider to the appropriate position according to the length of the infant's legs, tightens the fixing knob 18 at the front end, and locks the slider on the chute track through the fixing screw 17 to prevent the slider from moving back and forth due to leg movement during the examination; The telescopic plate 20 is nested in the telescopic slot 19 at the upper end of the leg slider 16 and can be slid left and right to adjust the distance between the legs. When adjusting, loosen the fixing knob 18 at the upper end of the telescopic slot 19, push the telescopic plate 20 to the target position, tighten the knob and fix it with the fixing screw 17 to ensure the stability of the lower limbs in the horizontal direction; The leg base plate 23 is connected to the front end of the telescopic plate 20 via the leg shaft 21. A fixed tooth 22 is provided at the lower end of the shaft. A spring 26 is connected to a movable tooth 27 in an opening at the lower end of the leg base plate 23. When the leg base plate 23 is pulled upward, the movable tooth 27 stretches the spring 26 and separates from the fixed tooth 22, allowing the angle of the leg base plate 23 to be freely adjusted. After release, the spring 26 pushes the movable tooth 27 to engage with the fixed tooth 22, locking the anatomical position of the lower limb and preventing angle deviation caused by changes in muscle tension during scanning. Furthermore, the bottom of the examination bed 2 is provided with a base 1, a circular groove is provided in the middle for rotationally connecting to a worm wheel 3, and a hole is provided on one side for rotationally connecting to a worm 25; the worm 25 engages with the worm wheel 3; Furthermore, the leg bottom plate 23 is L-shaped, with one side of the upper end fixedly connected to the leg fixing belt 24, and the other side having a groove for slidingly connecting the other end of the fixing belt; Furthermore, the structure of the hand fixing strap 15 is consistent with that of the leg bottom plate 23 and can rotate on the head plate 9.

[0010] Example 2 In this embodiment, the device can adapt to the scanning needs of infants and young children with multiple joints and complex body positions through multi-level adjustment; Cranial and brain-related structures, applicable to the cerebrum, cerebellum, brainstem, and skull base bones: the head base plate 6 can be rotated and adjusted from 0 to 60 degrees, and the limit column 11 is locked in multiple levels to ensure that the cranial scan baseline is accurately aligned with the CT gantry, clearly displaying the intracranial structure and skull base bone details; Cervical vertebra joint: The head plate 9 and the waist fixation plate 28 work together to limit the torso twisting. The angle adjustment of the head base plate 6 can maintain the physiological curvature of the cervical spine and avoid blurred spinal cord imaging caused by head shaking. It is suitable for the examination of cervical vertebral bodies, intervertebral discs and surrounding soft tissue lesions. Shoulder joint: The hand fixation strap 15 can be rotated and adjusted to a 0-90° abduction position, and can be fixed in position with the head plate 9 to fix the upper limbs on both sides of the body or in an abduction state, clearly displaying the shoulder glenoid fossa, proximal humeral epiphysis and surrounding ligament structures, suitable for the diagnosis of congenital shoulder dislocation, epiphyseal injury, etc. Elbow joint: The hand fixation strap can be locked at 15 degrees, and the forearm position can be fine-tuned with a 20-degree telescopic plate to ensure accurate scanning of the coronal and sagittal planes of the elbow joint. It is suitable for 3D reconstruction of supracondylar fractures of the humerus and developmental deformities of the elbow joint. Wrist and hand: The hand fixation strap 15 can lock the wrist joint in 30° dorsiflexion and 45° flexion, meeting the needs of fine imaging such as polydactyly and carpal bone dysplasia. Hip joint: The leg slider 16 moves forward and backward along the leg chute 5 to adapt to the hip joint positioning of infants and young children with different leg lengths; the telescopic plate 20 slides left and right to achieve 30°-60° abduction of the legs, combined with 15° internal rotation of the leg base plate 23, clearly displaying the acetabular index, femoral epiphysis position and joint space; Knee joint: The leg base plate 23 is locked in a 0-135° bending angle through the fixed teeth 22 and the movable teeth 27, meeting the requirements for tomographic scanning of distal femoral and proximal tibial epiphyseal injuries and knee ligament and meniscus lesions. It is particularly suitable for dynamic position assessment of congenital knee dislocation. Ankle and toes: The leg base plate 23 can lock the ankle in a neutral position, dorsiflex 10°, or plantar flex 20°, and cooperate with the telescopic plate 20 to fine-tune the foot distance, clearly displaying the distal tibia and fibula epiphysis, talus, and toe joint structure, suitable for precise imaging of congenital clubfoot and ankle fractures.

[0011] Example 3 In this embodiment, the device can be flexibly disassembled and installed by using a clamping plate to clamp it to the examination bed. In addition, in order to prevent artifacts from being generated during X-ray examination during CT imaging, the material selection must meet the requirements of being free of metal components, having good X-ray penetration, having uniform density, and not scattering or absorbing X-rays. Polymethyl methacrylate (PMMA, acrylic): low density, transparent, no metal components, low X-ray absorption rate, almost no artifacts; moderate mechanical strength, easy processing and molding, smooth surface, suitable for the production of lightweight and highly transparent clamping parts.

[0012] In summary, the present invention achieves free rotation of the rotating base plate 4 through the worm gear 3 and worm 25 mechanism, and can complete multi-directional scanning such as coronal and sagittal scans without manually moving the infant, thus avoiding examination delays and operational errors caused by repeated adjustments of body position; the head support plate can dynamically adjust the support angle and achieve multi-level locking according to the differences in infant head shape and the requirements of different scanning areas such as the skull and neck through the cooperation of the retractable limit column 11 and the limit rod 8, thereby ensuring precise alignment of the scanning plane with the target area and effectively reducing artifacts or missed scans caused by improper head posture; At the same time, the leg slider 16 that slides back and forth in the leg fixing structure and the telescopic plate 20 that telescopes left and right, combined with the angular rotation function of the L-shaped leg base 23, can fix the lower limbs in any anatomical position, such as extension, slight flexion, or abduction, to meet the scanning requirements of leg length, leg spacing, and joints such as hip and knee joints of infants of different body sizes, such as premature infants and full-term infants. This solves the problem that traditional one-way restraints cannot adapt to complex scanning angles, significantly improving the clarity of limb images and the diagnostic reliability. Finally, the waist fixing plate 28 achieves symmetrical and synchronous movement through the reverse threaded adjustment screw 13, which can quickly adapt to infants and young children with different waist circumferences, avoiding the risk of displacement or skin compression damage caused by traditional restraints due to loose or tight fixation. The hand fixing belt 15 is rotatable in the same way as the leg base plate 23, and is locked by the engagement of the spring 26 with the fixed teeth 22; it can adapt to a variety of different body posture examinations.
