Description

Technical Field

[0001] The invention relates to the technical field of fixing devices, in particular to a fixing device for taking X-rays of newborn babies. Background Art

[0002] Radiographs, also called imaging tests, provide pictures of the inside of the body (whole or part of it). Imaging helps doctors diagnose disease, determine its severity, and monitor patients after a disease is diagnosed. Most imaging tests are painless, relatively safe, and noninvasive (that is, they do not require cutting the skin or inserting equipment into the body). Imaging tests are used for: radiological tests [such as x-rays, angiograms, and computed tomography (CT)] and radionuclide scans [including positron emission tomography (PET)].

[0003] When newborns undergo imaging examinations such as X-rays and CT scans, special fixation devices are needed to ensure that they can maintain a stable and appropriate position, because infants cannot follow instructions well to maintain a specific posture, and the correct position is very important for obtaining accurate images. The use of appropriate fixation devices can not only improve the image quality, but also help reduce the need for repeated shooting, thereby reducing the radiation dose received by the infant.

[0004] Most traditional fixation devices use elastic bands to fix the newborn. There is no airbag cushioning, and the tightening force of the elastic band on the newborn cannot be adjusted. The elastic band has a small area. If the pressure of the elastic band is too high, it may injure the newborn. If the pressure of the elastic band is too low, it cannot provide enough pressure, and the newborn will move inside the device, affecting the filming effect. Summary of the invention

[0037] Furthermore, a pipe groove for laying a pipe between the airbag 6 and the inflatable part 4 is arranged in the frame 11, and the pipe between the airbag 6 and the inflatable part 4 adopts a flexible bellows, which is convenient for free stretching or contraction as the position of the airbag 6 changes.

[0038] The specific principles are as follows: Pull the vertical receiving plate 162 to both sides along the slide groove 13 to make the internal space between the tightening parts 16 large enough to facilitate the placement of the dummy 5 (simulating a newborn baby), turn the knob 154, and drive the non-return plate 151 to rotate through the threaded rod 153, so that the non-return plate 151 is in a state of being vertical to the slide groove 13, blocking the slider 163 to prevent the tightening part 16 from sliding downward, and at this time the first spring 165 is located in the notch 152. This setting of the notch 152 can prevent the rotation of the non-return plate 151 from affecting the first spring 165. The dummy 5 is placed in the frame 11, and the two arms of the dummy 5 are fixed on the right arm ring 23 and the left arm ring 24 respectively, and the head is placed on the headrest 25. The two legs are respectively passed through the right leg hole 34 and the left leg hole 35, and the two legs are limited. The dummy 5 is in a lying posture as a whole, and then the handle of the vertical receiving plate 162 is pulled and the knob 154 is turned to turn the check plate 151 into the concave hole of the slide groove 13. The tightening part 16 can slide inward along the slide groove 13 over the check plate 151, and the handle is pulled. The tightening part 16 is slowly slid toward the two sides of the dummy 5 by hand, and the elastic belt 166 will first contact the two sides of the body of the dummy 5. At this time, the dummy 5 will squeeze the elastic belt 166, and the elastic belt 166 will initially fix the dummy 5. The elastic belt 166 is squeezed by the dummy 5 and bends, pulling the horizontal receiving plate 161 downward, so that the horizontal receiving plate 161 rotates around the center point of the connecting wheel 169. When the connecting wheel 169 rotates with the horizontal receiving plate 161, the pull rope is pulled. Since the pull rope is fixed to the connecting ring 48 on the blocking ring 46, The pull rope drives the blocking ring 46 to move, so that the blocking ring hole 47 is located at the exhaust port 45. At this time, the second spring 49 is stretched, and the compressed air in the inflation bottle 41 is filled into the airbag 6 along the pipeline through the blocking ring hole 47 and the exhaust port 45. The airbag 6 swells and covers the body of the dummy 5, fixing the dummy 5 to prevent it from moving and affecting the filming effect. The airbag 6 increases the contact area between the tightening part 16 and the dummy 5, and more firmly binds the dummy 5 in the frame 11. In addition, the airbag 6 is relatively soft and will not cause damage to the dummy 5. After the filming is finished, the handle 43 is turned to drive the piston rod 42 to rotate and move outward, and the piston 44 moves backward with the piston rod 42 to reduce the air pressure in front of the inflation bottle 41, and the gas in the airbag 6 is pumped back into the inflation bottle 41 until the gas in the airbag 6 is completely pumped back, and the tightening part 16 is pulled to both sides, the elastic band 166 leaves the dummy 5 and returns to its original state, and the horizontal receiving plate 161 rotates around the center of the connecting wheel 169 under the action of the torsion spring. When the horizontal convex plate 167 abuts against the vertical convex plate 168, the horizontal receiving plate 161 stops rotating, the pull rope on the connecting wheel 169 rotates, and the pull rope is in a relaxed state, and the second spring 49 will move in the opposite direction. Pull the blocking ring 46 to make the blocking ring hole 47 leave the exhaust port 45, and the rest of the blocking ring 46 blocks the exhaust port 45. The inflation bottle 41 is closed, and the dummy 5 is taken out of the frame 11. The handle 43 is rotated in the opposite direction to drive the piston rod 42 to rotate and move inward. The piston 44 moves forward with the piston rod 42 to squeeze the internal gas and increase the air pressure in the inflation bottle 41, making it convenient to inflate the airbag 6 next time. Then, the rotating knob 154 is turned again to drive the check plate 151 to rotate through the threaded rod 153, so that the check plate 151 is in a state of vertical slide groove 13, blocking the slider 163 to prevent the tightening part 16 from sliding downward.
