[0030] Example 1:

[0031] This invention provides a multifunctional external fixation stretcher for spinal cord injury, such as... Figures 1-7 As shown, it includes: two main stretcher poles 1 and a mounting plate 2. Several movable plates 3 are slidably arranged between the two main stretcher poles 1. A spinal traction device is installed on the movable plates 3. The mounting plate 2 is located below the two main stretcher poles 1. The left and right ends of the main stretcher poles 1 are connected to the mounting plate 2 through connecting columns 4 respectively. A position adjustment device is set between the mounting plate 2 and the movable plates 3. A vital signs monitor and a wireless communication module are installed on the mounting plate 2. The vital signs monitor communicates with the medical and health big data sharing platform through the wireless communication module.

[0032] The working principle and beneficial effects of the above technical solution are as follows: The stretcher body includes two main stretcher poles 1. At least three movable plates 3 are set between the two main stretcher poles 1. Sliding holes are provided at both the front and rear ends of the movable plates 3. The movable plates 3 are slidably connected to the front and rear main stretcher poles 1 through the sliding holes. The widths of the movable plates 3 are different. The left movable plate 3 corresponds to the head of the injured person, the middle movable plate 3 corresponds to the torso of the injured person, and the right movable plate 3 corresponds to the lower limbs of the injured person. Below the movable plates 3 is a whole mounting plate 2. The mounting plate 2 is connected to the main stretcher poles 1 through connecting columns 4. Column 4 can limit the sliding of the movable plate 3, preventing it from detaching from the main stretcher rod 1. A position adjustment device is installed on the mounting plate 2, allowing adjustment of the position of each movable plate 3, thereby adjusting the position of the spinal traction device on the movable plate 3. This facilitates adaptation to patients of different body types. During use, the patient is moved onto the movable plate 3, and the spinal traction device on the movable plate 3 actively tractions the patient's spine on the stretcher, relieving pressure on the spinal cord caused by fractures and dislocations, and reducing secondary injuries such as vertebral misalignment and nerve compression caused by bumps during transport. To ensure the safe transport of the injured, the stretcher is constructed from high-strength, lightweight carbon fiber, providing excellent shock resistance and effectively reducing secondary injuries during transport. Additionally, a vital signs monitor and wireless communication module are mounted on mounting plate 2. The vital signs monitor collects real-time vital signs data from the injured person on the stretcher, including heart rate, blood pressure, and blood oxygen saturation. The wireless communication module connects to both the vital signs monitor and a medical and health big data sharing platform. This platform is a comprehensive information system that integrates, stores, analyzes, and shares various types of medical and health data. The wireless communication module uploads the vital signs data collected in real-time by the vital signs monitor to the platform. Medical staff at the rear hospital can obtain information about the injured person in advance through this platform. Combined with the patient's medical history stored on the platform (such as whether there are underlying conditions like spinal deformities or hypertension), a preliminary treatment plan can be developed during transport, avoiding repeated examinations after admission and saving valuable time for the treatment of spinal cord injury patients.

[0033] Example 2:

[0034] Based on the above embodiment 1, as follows Figure 1 , Figure 4 , Figure 5As shown, the spinal traction device includes a spinal support plate 5 and a spinal traction mechanism. The spinal support plate 5 is positioned above the movable plate 3. Fixing straps 6 are provided on the front and rear sides of the spinal support plate 5. The ends of the two fixing straps 6 away from the spinal support plate 5 are detachably connected to each other. A driving block 7 is provided on the side of the spinal support plate 5 near the movable plate 3. The driving block 7 is slidably connected to the upper surface of the movable plate 3. A spinal traction mechanism is provided on the movable plate 3. The spinal traction mechanism is connected to the driving block 7 through a traction strap 8.

[0035] The spinal traction mechanism includes a traction cover 9, which is mounted on a movable plate 3. A drive motor 10 is mounted on the inner wall of one side of the traction cover 9. A take-up shaft 11 is mounted at the output end of the drive motor 10. Two openings are provided on the side of the traction cover 9 near the drive block 7. A traction belt 8 is mounted at the opening. One end of the traction belt 8 is connected to the drive block 7. The other end of the traction belt 8 is connected to the take-up shaft 11.

[0036] A limiting block 12 is provided on the traction belt 8. The limiting block 12 is slidably connected to the inner wall of the opening. A first inclined surface is provided on one side away from each other of the two limiting blocks 12. Sliding holes are symmetrically provided at the front and rear ends of the traction cover 9. A limiting rod 13 is slidably provided in the sliding hole. A second inclined surface is provided at the end of the limiting rod 13 near the traction belt 8. The end of the limiting rod 13 away from the second inclined surface extends to the outside of the traction cover 9 and is provided with a pull plate 14. A return spring 15 is sleeved on the limiting rod 13.

[0037] The working principle and beneficial effects of the above technical solution are as follows: First, adjust the position of the movable plate 3 according to the body shape of the injured person so that the spinal traction device can be aligned with the corresponding position of the injured person. Among them, the left spinal support plate 5 is used to support the head of the injured person, and the neck of the injured person is fixed by the fixing straps 6 on both sides of the left spinal support plate 5. The middle spinal support plate 5 is used to support the torso of the injured person, and the waist or chest of the injured person is fixed by the fixing straps 6 on both sides of the middle spinal support plate 5. The right spinal support plate 5 is used to support the lower limbs of the injured person, and the lower limbs of the injured person are fixed by the fixing straps 6 on both sides of the right spinal support plate 5. The two ends of the fixing straps 6 are fixed. The connection is detachable, and the connection method can be Velcro or snap fasteners, facilitating quick connection or removal of the fixing strap 6. After the fixing strap 6 is fixed, the drive motor 10 is started. The drive motor 10 rotates, driving the take-up shaft 11 to rotate. The rotation of the take-up shaft 11 allows the traction strap 8 to wrap around it. The traction strap 8 drives the limiting block 12 to slide into the traction cover 9 at the opening. At the same time, the traction strap 8 drives the drive block 7 to slide on the upper surface of the moving plate 3. The drive block 7 drives the spinal support plate 5 to move to the left. The left-side fixing strap 6 provides cervical traction, and the middle fixing strap 6 provides lumbar traction. Alternatively, thoracic traction can be used, with the right-side fixation strap 6 securing the lower limbs. The spinal traction device provides active traction to the spine of the spinal cord injury patient, effectively repositioning the misaligned vertebrae, reducing spinal cord compression time, and preventing secondary injury during transport. When the first inclined surface of the limiting block 12 contacts the second inclined surface of the limiting rod 13, the first inclined surface can slide along the second inclined surface, causing the limiting rod 13 to slide outwards towards the traction cover 9. The pull plate 14 is connected to the traction cover 9 via a return spring 15. At this time, the return spring 15 is stretched. When the limiting block 12 passes the limiting rod 13, the elastic force of the return spring 15... When the limit rod 13 returns to its original position, the drive motor 10 stops rotating, and the spinal traction mechanism completes the traction of the spine. By limiting the limit rod 13, the spinal support plate 5 can be prevented from moving to the right, which improves the reliability of spinal traction and achieves stable fixation of the spinal cord injury patient. After the transfer is completed, first remove each fixation strap 6, then move the patient away, then control the drive motor 10 to rotate in the opposite direction, so that the traction strap 8 is released from the winding shaft 11, and the pull plate 14 is pulled outward, so that the limit rod 13 slides outward. Finally, the spinal support plate 5 can be manually reset for the next use.

[0038] Example 3:

[0039] Based on Example 2, such as Figure 1 As shown, a pad 16 is provided on the upper surface of the spinal support plate 5.

[0040] The working principle and beneficial effects of the above technical solution are as follows: The pad 16 is made of soft and elastic material, such as sponge pad, which can improve the comfort of the injured person on the spinal support plate 5 and prevent the injured person from being bumped, thus improving safety.

[0041] Example 4:

[0042] Based on any one of Examples 1-3, such as Figure 2 As shown, shock-absorbing devices 17 are respectively installed at the four corners of the lower surface of the mounting plate 2, and casters 18 are installed at the lower end of the shock-absorbing devices 17.

[0043] The working principle and beneficial effects of the above technical solution are as follows: During the process of transporting the wounded, the universal wheels 18 can improve the flexibility of the stretcher, making it easier to transport the wounded and reducing the burden on medical staff. By setting a shock-absorbing device 17 on the universal wheels 18, the shock-absorbing device 17 can be a shock absorber, which can improve the shock absorption effect of the stretcher and facilitate the rapid and stable transfer of the wounded in complex terrain.

[0044] Example 5:

[0045] Based on any one of Examples 1-4, such as Figures 1-3 As shown, protective plates 19 are provided at both the front and rear ends of the movable plate 3.

[0046] The working principle and beneficial effects of the above technical solution are as follows: the guard plate 19 is perpendicular to the moving plate 3, and the upper end of the guard plate 19 is higher than the moving plate 3. The guard plate 19 can limit and protect the front and rear sides of the injured person, prevent the injured person from falling off the stretcher, and improve the safety of the stretcher.

[0047] Example 6:

[0048] Based on any one of Examples 1-5, such as Figure 1 , Figure 2 As shown, cold compress bag placement boxes 20 are set on the front and rear sides of the movable plate 3.

[0049] The working principle and beneficial effects of the above technical solution are as follows: the cold compress bag placement box 20 can hold multiple cold compress bags, which makes it convenient for medical staff to apply cold compresses to the injured parts of the patient at any time to reduce swelling and pain.

[0050] Example 7:

[0051] Based on any one of Examples 1-6, such as Figures 1-3As shown, a foot fixing device is provided on the rightmost movable plate 3. The foot fixing device includes a fixing cylinder 21 with a square cross-section. One end of the fixing cylinder 21 is connected to the upper surface of the movable plate 3. First mounting shafts are provided on the front and rear sides of the fixing cylinder 21. A first protective sleeve 22 is provided outside the first mounting shaft. An adjusting column 23 is slidably provided inside the fixing cylinder 21. A threaded hole is provided in the center of the adjusting column 23. Second mounting shafts are provided on the front and rear sides of the adjusting column 23. A second protective sleeve 24 is provided outside the second mounting shaft. A screw 25 is provided inside the fixing cylinder 21. The lower end of the screw 25 is rotatably connected to the upper surface of the movable plate 3. The upper end of the screw 25 passes through the threaded hole and is provided with an adjusting wheel 26. The screw 25 is connected to the threaded hole through an external thread.

[0052] The working principle and beneficial effects of the above technical solution are as follows: When the injured person is transferred to the stretcher, the injured person's ankle is placed between the first protective sleeve 22 and the second protective sleeve 24. Then, the adjusting wheel 26 is rotated, which drives the screw 25 to rotate. The rotation of the screw 25 drives the adjusting column 23 to slide downward in the fixed cylinder 21. The second protective sleeve 24 presses on the injured person's ankle. At this time, the injured person's foot can be fixed, which makes it easier to pull the injured person's spine to the left without causing the injured person to move as a whole. This improves the stability of spinal traction and enhances the safety of the injured person being transported by stretcher.

[0053] Example 8:

[0054] Based on any one of Examples 1-7, such as Figure 2 As shown, the position adjustment device corresponds one-to-one with the moving plate 3. The position adjustment device includes an electric push rod 27, which is mounted on the mounting plate 2. The output end of the electric push rod 27 is provided with a moving block 28. The lower end of the moving block 28 is slidably connected to the upper surface of the mounting plate 2, and the upper end of the moving block 28 is connected to the lower surface of the moving plate 3.

[0055] The working principle and beneficial effects of the above technical solution are as follows: When the electric push rod 27 retracts, it can drive the moving block 28 to slide to the left on the upper surface of the mounting plate 2, thereby driving the moving plate 3 to move to the left. When the electric push rod 27 extends, it can drive the moving block 28 to slide to the right on the upper surface of the mounting plate 2, thereby driving the moving plate 3 to move to the right. By setting a position adjustment device corresponding to the moving plate 3, the position of a single moving plate 3 can be flexibly adjusted, which facilitates the adjustment of the position of the spinal traction device on the moving plate 3, thereby adapting to patients of different body types.

[0056] Example 9:

[0057] Based on any one of Examples 2-8, such as Figure 6 , Figure 7As shown, an auxiliary support device is provided between two adjacent movable plates 3. The auxiliary support device includes: a slider 29, which is slidably connected to the upper surface of the mounting plate 2; a cylinder 30 is provided on the slider 29; a sliding rod 31 is slidably provided inside the cylinder 30; a mounting hole is provided inside the sliding rod 31; a support column 32 is slidably provided inside the mounting hole; the support column 32 is connected to the bottom wall of the mounting hole through a connecting spring 33; a main support seat 34 is provided at the upper end of the support column 32; a support air cushion 35 is provided on the main support seat 34; and the upper surface of the support air cushion 35 is... The surface is higher than the upper surface of the spinal support plate 5. Side support seats 36 are symmetrically arranged on both sides of the sliding rod 31. One end of the side support seat 36 is hinged to the side wall of the sliding rod 31, and the other end is hinged to the side wall of the movable plate 3. The upper end of the side support seat 36 contacts the bottom surface of the support air cushion 35. An installation cavity 37 is provided inside the side support seat 36, and a rotating shaft 38 is installed inside the installation cavity 37. The front and rear ends of the rotating shaft 38 are rotatably connected to the inner wall of the installation cavity 37, respectively. A spring is installed on the rotating shaft 38, and one end of the spring is connected to the rotating shaft 38. 8. The other end of the spring is connected to the inner wall of the mounting cavity 37. One end of the support air cushion 35 extends into the mounting cavity 37 and is connected to the outer wall of the rotating shaft 38. Two air storage boxes 39 are symmetrically arranged near the upper outer wall of the support column 32. The upper end of the air storage box 39 is connected to the support air cushion 35 through the air pipe 40. A piston plate 41 is slidably arranged inside the air storage box 39. A first rack 42 is arranged at the center of the piston plate 41. A through hole is provided on the side of the air storage box 39 away from the support column 32. The first rack 42 is close to the side support seat 3. One end of the 6 extends through a through hole to the outside of the gas storage box 39. A vertical plate 43 is provided on the outer wall of the gas storage box 39. A rotating shaft is provided on the front side of the vertical plate 43. A gear 45 is provided on the rotating shaft. The gear 45 meshes with the first rack 42. A second rack 44 is provided on the side of the gear 45 away from the first rack 42. The second rack 44 is parallel to the first rack 42. The second rack 44 is slidably connected to the front side wall of the vertical plate 43. The end of the second rack 44 away from the gas storage box 39 is hinged to the slide table 46. The slide table 46 is slidably provided on the side wall of the side support seat 36.

[0058] The working principle and beneficial effects of the above technical solution are as follows: The two ends of the supporting air cushion 35 are respectively wrapped around the rotating shaft 38. The supporting air cushion 35 located on the main support seat 34 is filled with gas and is in an expanded state. Under the support of the main support seat 34, the supporting air cushion 35 between the left moving plate 3 and the middle moving plate 3 can support the neck of the injured person, and the supporting air cushion 35 between the middle moving plate 3 and the right moving plate 3 can support the waist of the injured person, avoiding secondary injury caused by the neck or waist of the injured person being suspended or unsupported. When the two moving plates 3 move towards each other, the moving plate 3 drives the sliding rod 31 to slide downward in the cylinder 30 through the side support seat 36. The angle between the side support seat 36 and the sliding rod 31 decreases. The side support seat 36 drives the second rack 44 to slide towards the air storage box 39. The second rack 44 drives the first rack 42 to slide away from the air storage box 39 through meshing with the gear 45. The first rack 42 drives the piston plate 41 to slide away from the support column 32. As the piston plate 41 slides, the air pressure on the side near the support column 32 decreases, and the gas in the support air cushion 35 flows into the space on the side of the piston plate 41 near the support column 32. At the same time, as the distance between the two moving plates 3 decreases, the distance between the upper ends of the two side support seats 36 also decreases accordingly. Under the action of the spring, the rotating shaft 38 rotates and rolls the end of the support air cushion 35 onto the rotating shaft 38. During the rolling process, excess gas can be accelerated and squeezed into the air storage box 39, while ensuring that the support air cushion 35 located on the main support seat 34 can remain in an expanded state. This allows the support air cushion 35 to support the wounded while also adapting to the distance between the moving plates 3, improving the adaptability of the support air cushion 35. When the distance between the two moving plates 3 is shortened, it indicates that the wounded person is small in size, and the wounded person is mostly a woman or a child. As the sliding rod 31 slides downward, the connecting spring 33 extends, which can reduce the supporting force of the support air cushion 35 and prevent the supporting force of the support air cushion 35 from being too large and causing secondary injury to the wounded person.When the two movable plates 3 move away from each other, the movable plates 3 drive the sliding rod 31 to slide upward in the cylinder 30 via the side support 36, increasing the angle between the side support 36 and the sliding rod 31. The side support 36 drives the second rack 44 to slide away from the gas storage tank 39 on the front side wall of the vertical plate 43. At the same time, the slide table 46 slides on the side wall of the side support 36. The second rack 44, through meshing with the gear 45, drives the first rack 42 to slide into the gas storage tank 39. The first rack 42 drives the piston plate 41 to slide closer to the support column 32. The piston plate 41 can then squeeze the gas stored in the gas storage tank 39 into the air pipe 40 and flow into the support air cushion 35 through the air pipe 40. As the distance between the two movable plates 3 increases, the distance between the upper ends of the two side support 36 increases accordingly. Part of the support air cushion 35 located in the mounting cavity 37 is pulled out to the outside of the mounting cavity 37 and is pulled out as the gas in the gas storage tank 39 flows into the support air cushion 35. The support air cushion 35 outside the mounting cavity 37 is filled with gas and expands. Both ends of the support air cushion 35 are supported by the upper ends of the side support seats 36. The expanded section of the support air cushion 35 can adapt to the distance between the two moving plates 3, thus providing stable support for the patient's waist or neck. The increased distance between the two moving plates 3 indicates that the patient is relatively large, and is likely an adult male. As the sliding rod 31 slides upward, the connecting spring 33 compresses and pushes the support column 32 upward within the mounting hole. The support column 32 drives the main support seat 34 upward, which in turn pushes the support air cushion 35 upward, thereby enhancing support for the patient's neck or waist. Because the patient is in a spinal traction state, while enhancing support for the neck or waist, the neck or waist protrudes upward. For larger patients, this enhances the spinal traction force, avoids insufficient traction, improves the reliability of spinal traction, completes the stable fixation of spinal cord injury patients, and improves the safety of transport.
