[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Please see the appendix Figure 1 - Appendix Figure 12This invention provides a multifunctional patient positioning support device for emergency transport, including a lifting frame 1. Multiple comfort mechanisms 5 are arranged around the lifting frame 1. A deformation mechanism 2 is arranged above the lifting frame 1. The comfort mechanisms 5 are used to reduce vibration forces and can connect the deformation mechanism 2 and the lifting frame 1. A stretcher mechanism 3 is arranged on the top of the deformation mechanism 2. The stretcher mechanism 3 functions as a stretcher and can be detached from the deformation mechanism 2. A rotating connection mechanism 4 is arranged on the top of the stretcher mechanism 3, which connects to the stretcher mechanism 3 and can maintain the stretcher mechanism 3 in an open state. Two rotating arms 7 are rotatably connected to the bottom sides of the lifting frame 1. A movable base frame 8 is arranged at the bottom of the lifting frame 1, and the interior of the movable base frame 8 is rotatably connected to... There are two hydraulic cylinders 29. Two rotating rods 6 are rotatably connected to the inner side of the movable base frame 8. The output end of hydraulic cylinder 29 is rotatably connected to the outside of the rotating rods 6. The bottom of four rotating arms 7 are fixedly connected to the two ends of the two rotating rods 6 respectively. When hydraulic cylinder 29 is activated, it can push the rotating rods 6 to rotate, thereby driving the rotating arms 7 to rotate. When the rotating arms 7 approach the vertical state, it drives the lifting frame 1 to rise, thereby making the device higher. When hydraulic cylinder 29 pulls the rotating rods 6, it drives the rotating arms 7 to rotate to a horizontal state through the rotating rods 6, thereby making the lifting frame 1 lower, thereby making the device lower. When one hydraulic cylinder 29 is activated, the device can be raised on one side and lowered on the other, which is suitable for transporting people down from an incline or an ambulance.
[0020] The deformation mechanism 2 includes a mounting frame 201, which provides the mounting position. A rotating frame 202 is rotatably connected to one side of the top of the mounting frame 201. A driving rod 203 is rotatably connected to one side of the rotating frame 202. A hydraulic cylinder 204 is rotatably connected to the middle of the bottom of the mounting frame 201. A driving frame 205 is rotatably connected to the middle of the top of the mounting frame 201. Rotation of the rotating frame 202 can push or pull the driving rod 203. When the rotating frame 202 pushes the driving rod 203, it can cause the driving frame 205 to tilt. When the rotating frame 202 pulls the driving rod 203, it can cause the driving frame 205 to rotate into a flat position. The output end of the hydraulic cylinder 204 is rotatably connected to one side of the rotating frame 202, and the driving rod 203 is away from the rotating frame. One end of the frame 202 is rotatably connected to the side of the drive frame 205 near the rotating frame 202. A fixing plate 206 is fixedly connected to the top of the mounting frame 201, providing the mounting position. A leg rotating plate 207 is fixedly connected to the top of the rotating frame 202. An upper body rotating plate 208 is fixedly connected to the bottom of the drive frame 205. A sliding groove 209 is provided in the middle of the fixing plate 206, and a sliding plate 210 is slidably connected inside the sliding groove 209. A sliding plate 211 is fixedly connected to the top of the mounting frame 201. The cooperation between the sliding plate 210 and the sliding groove 209 can limit the movement trajectory of the sliding plate 211. A fixing stop bar 213 is fixedly connected to one side of the top of the fixing plate 206, and a moving stop bar 214 is fixedly connected to one side of the sliding plate 211. When the distance between the fixed stop bar 213 and the movable stop bar 214 is at its minimum, the stretcher mechanism 3 can be clamped, thereby maintaining the stability of the stretcher mechanism 3. The rotating frame 202 is fixedly connected to the auxiliary support frame 215 away from the driving rod 203. The bottom of the sliding plate 211 is slidably connected to the top of the fixed plate 206. When the patient cannot lie down, the hydraulic cylinder 204 is activated. The output end of the hydraulic cylinder 204 retracts, which can drive the end of the rotating frame 202 near the hydraulic cylinder 204 to rotate upward, thereby driving the other end of the rotating frame 202 to rotate downward, thereby driving the leg rotating plate 207 to rotate downward. When the end of the rotating frame 202 near the hydraulic cylinder 204 rotates upward, it will also move closer to the fixed plate 206. This causes the driving rod 203 to move away from the auxiliary support frame 215, which in turn causes the bottom end of the driving frame 205 to rotate downwards, while the end of the driving frame 205 with the upper body rotating plate 208 rotates upwards. This causes the leg rotating plate 207 to move downwards and the upper body rotating plate 208 to move upwards, thus forming a new chair shape, making it convenient for the patient to sit. When the patient is lying down and unable to get out of bed and needs to be transferred, the hydraulic cylinder 212 is activated. The hydraulic cylinder 212 causes the sliding plate 210 to move away from the fixed stop bar 213, which in turn causes the sliding plate 211 to move away from the fixed stop bar 213, thereby moving the stretcher mechanism 3 on the sliding plate 211 to the patient's bed.To facilitate the patient's turning and lying on the stretcher mechanism 3, hydraulic cylinder 3 212 is activated again, causing the sliding plate 210 to move towards the fixed stop 213. This, in turn, moves the sliding plate 211 towards the fixed stop 213, allowing the stretcher mechanism 3 to reset. The patient can then be moved onto the device, saving time and effort, improving comfort, reducing patient pain, and avoiding the need for medical staff or family members to lift the patient onto the device or hold them by the corners of a sheet or other object. Such methods of patient transfer can easily lead to significant limb twisting, increasing patient suffering.
[0021] The stretcher mechanism 3 includes a waist plate 301, an upper body plate 302, and a leg plate 303. Two fixed handrails 304 are fixedly connected to the side of the upper body plate 302 away from the waist plate 301. A mounting base 305 is fixedly connected to the top of one side of the mounting frame 201, providing an installation position. A rotating cover 306 is rotatably connected to the top side of the mounting base 305. The rotating cover 306, in cooperation with the mounting base 305, can clamp the fixed handrails 304, thus facilitating the installation of the waist plate 301, upper body plate 302, and leg plate 303. A fixed rod 307 is fixedly connected inside the side of the mounting base 305 away from the rotating cover 306. A rotating sleeve 308 is rotatably connected to the outside of the fixed rod 307. The rotating sleeve 308 has an internal structure... A torsion spring 309 is present. A locking arm 310 is fixedly connected to the outside of the rotating sleeve 308. A locking block 311 is fixedly connected to the side of the locking arm 310 near the rotating cover 306. After the locking block 311 moves to the top of the anti-slip pad 313, it can press down on the rotating cover 306, preventing it from tilting. When the rotating cover 306 has an upward rotational force under external force, it will press even tighter against the locking block 311, preventing the rotating cover 306 from opening. Therefore, the rotating cover 306 can only be opened after the locking block 311 is rotated upwards away from the top of the rotating cover 306. A lever ear 312 is fixedly connected to the side of the locking arm 310 away from the rotating cover 306. The inner side of the leg plate 303 away from the waist plate 301... Two storage slots 315 are provided, with a limiting plate 316 slidably connected inside each slot 315. A movable hand lever 317 is fixedly connected to the side of the limiting plate 316 away from the waist plate 301. The limiting plate 316 and the storage slot 315 are interference-fitted; the movable hand lever 317 can only be pulled out of the storage slot 315 by pulling it forcefully. The movable hand lever 317 is retracted to prevent it from affecting the rotation of the leg plate 303. One end of the torsion spring 309 is fixedly connected to the inside of the rotating sleeve 308, and the other end of the torsion spring 309 is fixedly connected to the outside of the fixed rod 307. Anti-slip pads 313 are provided on the top of the mounting base 305 and in the groove of the rotating cover 306. The leg rotating plate 207 is away from the waist plate 301. An anti-slip sleeve 314 is fixedly connected to the top of one end of the mounting base 305. A torsion spring 309 is sleeved on the outside of the fixed rod 307. The movable hand handle 317 passes through one side of the leg plate 303. When medical staff need a stretcher, they can pull the lever ear 312 downwards, which will drive the locking arm 310 to rotate downwards. When the locking arm 310 rotates downwards, it will drive the rotating sleeve 308 to rotate, thereby compressing the torsion spring 309. After the locking arm 310 rotates downwards, the locking block 311 can move away from the end of the rotating cover 306 away from the mounting base 305. At this time, the rotating cover 306 can be rotated upwards to open. Then, the fixed hand handle 304 can be flipped upwards and pulled away from the leg rotating plate 207.The leg plate 303 is disengaged from the anti-slip sleeve 314. The leg plate 303, upper body plate 302, and waist plate 301 are then unfolded into a flat position. The rotating connecting mechanism 4 is used to maintain the stretcher mechanism 3 in its extended state, allowing it to be used as a stretcher. The stretcher mechanism 3 can then be removed from the top of the deformation mechanism 2 to become a stretcher. During installation, the leg plate 303 is first inserted into the anti-slip sleeve 314. Then, the rotating connecting mechanism 4 is used to release the extended state of the stretcher mechanism 3. The upper body plate 302 is rotated, and the fixed handrail 304 is placed into the mounting base 305 and the rotating pressure cover 306 to clamp the fixed handrail 304. The rotating connecting mechanism 4 is then used to maintain the stretcher mechanism 3 in a supported state, thus completing the installation of the stretcher mechanism 3.
[0022] The rotating connection mechanism 4 includes four base cylinders 401, which provide installation positions. One end of each base cylinder 401 is fixedly connected to both sides of the waist plate 301. A limit slider 402 is slidably connected inside each base cylinder 401, serving both a limiting and piston function. A movable arc rod 403 is fixedly connected to one end of the limit slider 402, providing a connecting mechanism. A storage tank 404 is fixedly connected to the outside of each base cylinder 401. An inner cylinder 405 is fixedly connected to one end of the storage tank 404, providing an installation position. A return spring 406 is installed inside the inner cylinder 405, and a limit ring 407 is slidably connected inside the inner cylinder 405, providing a limiting function. Functionally, a stopper rod 408 is fixedly connected to the middle of the limiting ring 407. A stopper gasket 409 is fixedly connected to the end of the stopper rod 408 away from the inner cylinder 405. After the stopper gasket 409 is inserted into the channel between the base cylinder 401 and the loading tank 404, it can prevent the movable arc rod 403 from retracting into the interior of the base cylinder 401. A rotating cap 410 is fixedly connected to the end of the stopper rod 408 away from the stopper gasket 409. Two locking ears 411 are fixedly connected to the outside of the rotating cap 410. Two locking frames 412 are fixedly connected to the end of the loading tank 404 away from the stopper gasket 409. After the locking ears 411 and the locking frames 412 are engaged, the stopper gasket 409 can be kept inserted in the channel between the base cylinder 401 and the loading tank 404. The ends of the four movable arc rods 403 away from the limiting slider 402 are respectively... The upper body plate 302 and leg plate 303 are fixedly connected to both sides. The return spring 406 is sleeved on the outside of the stopper rod 408. The stopper rod 408 passes through the inner cylinder 405 near the stopper 409. Pressing the rotating cap 410 towards the stopper 409 will drive the stopper rod 408 to move into the container 404, thereby blocking the pipe connected to the base cylinder 401 with the stopper 409. Rotating the rotating cap 410 will drive the locking ear 411 to rotate into the locking frame 412, thus maintaining the seal of the container 404. Therefore, the liquid in the base cylinder 401 cannot continue to flow into the container 404, and the limiting slider 402 cannot move downward along the base cylinder 401, thereby enabling the waist plate 301 to be closed. The upper body plate 302 and leg plate 303 are supported, and the waist plate 301, upper body plate 302 and leg plate 303 are maintained in a supported state. When the rotating cap 410 is rotated in the opposite direction, and the locking ear 411 is disengaged from the inside of the locking frame 412, the rotating cap 410 is released. Under the elastic action of the return spring 406, the limiting ring 407 moves towards the rotating cap 410, which in turn moves the stop rod 408 and the stop pad 409 towards the inner cylinder 405. Therefore, the stop pad 409 will no longer block the pipe connecting the base cylinder 401 and the storage tank 404. At this time, the liquid in the base cylinder 401 will flow into the interior of the storage tank 404, which will allow the movable arc rod 403 to retract into the interior of the base cylinder 401.This allows the upper body plate 302 or the leg plate 303 to rotate following the upper body rotating plate 208 or the leg rotating plate 207.
[0023] The comfort mechanism 5 includes multiple fixed cylinders 501, which provide installation positions. The external surfaces of each fixed cylinder 501 are fixedly connected to the perimeter of the lifting frame 1. A buffer spring 503 is installed inside each fixed cylinder 501. A movable ring 502 is slidably connected inside each fixed cylinder 501. Multiple liquid passage holes 504 are opened inside the movable ring 502, limiting the flow rate of liquid inside the fixed cylinder 501. Connecting cranks 505 are fixedly connected to the top of the movable ring 502. The tops of the multiple connecting cranks 505 are fixedly connected to the perimeter of the mounting frame 201. The buffer springs 503... One end of the buffer spring 503 is fixedly connected to the bottom of the fixed cylinder 501, and the other end of the buffer spring 503 is fixedly connected to the bottom of the moving ring 502. When vibration occurs, the mounting frame 201 moves downward, which can compress the buffer spring 503. At the same time, the liquid in the fixed cylinder 501 needs to flow out through the liquid passage hole 504, thus limiting the flow rate of the liquid. Subsequently, when the moving ring 502 moves upward under the reaction force of the buffer spring 503, the upward speed of the moving ring 502 can be limited. Thus, while buffering the vibration force, the spring force can also increase the vibration force.
[0024] Working principle: When the patient is unable to lie down, hydraulic cylinder 204 is activated. The output end of hydraulic cylinder 204 retracts, causing the end of rotating frame 202 near hydraulic cylinder 204 to rotate upwards. This causes the other end of rotating frame 202 to rotate downwards, thereby causing the leg rotating plate 207 to rotate downwards. As the end of rotating frame 202 near hydraulic cylinder 204 rotates upwards, it also moves towards the fixed plate 206, causing the driving rod 203 to move away from the auxiliary support frame 215. This causes the bottom end of driving frame 205 to rotate downwards, while the end of driving frame 205 with the upper body rotating plate 208 rotates upwards. This allows the leg rotating plate 207 to move downwards and the upper body rotating plate 208 to move upwards, thus forming a new chair shape, making it convenient for the patient to sit. When the patient is unable to get out of bed and needs to be transferred, The hydraulic cylinder 212 can be activated, which can move the slide plate 210 away from the fixed stop 213. This, in turn, can move the sliding plate 211 away from the fixed stop 213, thereby moving the stretcher mechanism 3 on the sliding plate 211 to the patient's bed, making it easier for the patient to turn over and lie on the stretcher mechanism 3. At this time, the hydraulic cylinder 212 can be activated again, causing the slide plate 210 to move towards the fixed stop 213, thereby moving the sliding plate 211 towards the fixed stop 213. This will allow the stretcher mechanism 3 to return to its original position, at which point the patient can be moved onto the device. This saves time and effort, improves comfort, reduces patient pain, and avoids the need for medical staff or family members to lift the patient onto the device or grab the four corners of a sheet or other object to place the patient on the device. Such methods of transferring patients can easily lead to large twisting of the patient's limbs, increasing the patient's pain. When medical staff need a stretcher, the lever 312 is pulled downwards, causing the locking arm 310 to rotate downwards. This downward rotation of the locking arm 310 causes the rotating sleeve 308 to rotate, compressing the torsion spring 309. After the locking arm 310 rotates downwards, the locking block 311 moves away from the end of the rotating cover 306 away from the mounting base 305. The rotating cover 306 can then be rotated upwards to open. The fixed handle 304 is then flipped upwards and pulled away from the leg plate 207, causing the leg plate 303 to move away from the anti-slip sleeve 314. The leg plate 303 is then... 3. The upper body plate 302 and waist plate 301 are unfolded into a flat position. The stretcher mechanism 3 is then kept in an open state by the rotating connection mechanism 4. At this time, it can be used as a stretcher. The stretcher mechanism 3 can be taken out from the top of the deformation mechanism 2 to become a stretcher. During installation, first insert the leg plate 303 into the anti-slip sleeve 314. Then, use the rotating connection mechanism 4 to release the open state of the stretcher mechanism 3. Rotate the upper body plate 302 and put the fixed hand handle 304 into the mounting base 305 and the rotating pressure cover 306 to clamp the fixed hand handle 304. Then, use the rotating connection mechanism 4 to keep the stretcher mechanism 3 in a supported state. The installation of the stretcher mechanism 3 can be completed. Pressing the rotating cap 410 towards the stopper 409 causes the stopper rod 408 to move into the container 404, thus blocking the pipe connected to the base cylinder 401 using the stopper 409. Rotating the rotating cap 410 then causes the locking ear 411 to rotate into the locking frame 412, maintaining the seal of the container 404. Therefore, liquid in the base cylinder 401 cannot continue to flow into the container 404, preventing the limiting slider 402 from moving downwards along the base cylinder 401. This supports the waist plate 301, upper body plate 302, and leg plate 303, maintaining their supported state. When the rotating cap 410 is... 10. After the reverse rotation causes the locking lug 411 to leave the inside of the locking frame 412, the rotating cap 410 is released. Under the elastic action of the return spring 406, the limiting ring 407 can be driven to move towards the rotating cap 410. This will then drive the plug rod 408 and the plug pad 409 to move towards the inner cylinder 405. Therefore, the plug pad 409 will no longer block the pipe connecting the base cylinder 401 and the storage tank 404. At this time, the liquid in the base cylinder 401 will flow into the interior of the storage tank 404, which will allow the movable arc rod 403 to retract into the interior of the base cylinder 401. This will enable the upper body plate 302 or the leg plate 303 to rotate with the upper body rotating plate 208 or the leg rotating plate 207.
