The side rod 91 is installed on the lifting plate 22, the lifting ring 9 is installed on the side rod 91, and the rotating column 92 is rotatably installed on the lifting ring 9. One end of the rotating column 92 is connected with the output end of the motor 6. By setting the lifting ring 9 and the side rod 91 to cooperate with each other, the rotating column 92 can be conveniently supported. The rotating column 92 is rotatably connected with the lifting ring 9 through a bearing. The stretcher 1 is provided with a guide rod 8. One end of the guide rod 8 is provided with a connecting ring 83, the connecting ring 83 is provided with a connecting block 81, the guide rod 8 is slidably provided with a guide ring 84, the guide ring 84 is provided with a side block 82, and the guide ring 84 is slidably connected with the guide rod 8. By setting the guide ring 84 and the guide rod 8 to cooperate with each other, the moving plate 31 can be conveniently guided and limited.By setting the connecting ring 83 and the connecting block 81 to cooperate with each other, the guide rod 8 can be easily supported. The lifting assembly includes a lifting rod 3 and a moving plate 31. The moving plate 31 is installed on the side block 82, and the lifting rod 3 is installed on the moving plate 31. The lifting rod 3 is equipped with an anti-slip pad. By setting the lifting rod 3, the stretcher 1 can be easily moved. By setting the anti-slip pad, the friction of the lifting rod 3 can be increased. The moving assembly includes a rack 7, a gear 71, a base rod 72, and a base column 73. The gear 71 is installed on the rotating column 92. The gear 71 meshes with multiple racks 7. One rack 7 is connected to one moving plate 31 through the base rod 72, and another rack 7 is connected to another moving plate 31 through the base column 73. By setting the base rod 72 and the base column 73, the rack 7 can be easily supported.

[0021] In this embodiment, as Figure 6 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the support assembly includes a second connecting plate 5, a support column 51, a lifting frame 52, and a lifting rod 53. The lifting rod 53 is mounted on the stretcher 1, the second connecting plate 5 is mounted on the lifting rod 53, the support column 51 is mounted on the second connecting plate 5, and the lifting frame 52 is mounted on the support column 51. By setting the second connecting plate 5, support column 51, lifting frame 52, and lifting rod 53, the air chamber 4 can be easily supported. The inflation assembly includes an air chamber 4, an air pipe 41, a push-pull rod 42, a piston 43, and an airbag 44. The air chamber 4 is mounted on the lifting frame 52, the push-pull rod 42 is mounted on the moving plate 31, one end of the push-pull rod 42 is mounted on the piston 43, and the airbag 44 is mounted on the support plate 16. The air chamber 4 is connected to the airbag 44 through the air pipe 41. The stretcher includes an air chamber 4, an air tube 41, a push-pull rod 42, a piston 43, and an air bag 44. When the motor 6 starts, it easily drives the rotating column 92 to rotate. When the rotating column 92 rotates, it drives the gear 71 to rotate. When the gear 71 rotates, it drives the rack 7 to move. When the rack 7 moves, it drives the moving plate 31 to move, removing the lifting rod 3 from the stretcher 1. The moving plate 31 then drives the push-pull rod 42 to move. When the push-pull rod 42 moves, it drives the piston 43 to move. The piston 43 then delivers gas from the air chamber 4 to the air bag 44 through the push-pull rod 42. The air bag 44 then inflates, protecting the patient's arms and legs from collisions with the side frame 12 and preventing secondary injuries, thus improving the stretcher's safety.

[0022] In this embodiment, as Figures 1-12 As shown in the figure, the working process of transferring a critically ill patient using a multi-functional stretcher provided in this embodiment is as follows: Step 1: The motor 6 starts and drives the rotating column 92 to rotate. When the rotating column 92 rotates, it drives the gear 71 to rotate. When the gear 71 rotates, it drives the rack 7 to move. When the rack 7 moves, it drives the base rod 72 and the base column 73 to move, which in turn drives the moving plate 31 to move. When the moving plate 31 moves, it drives the lifting rod 3 to move, and removes the lifting rod 3 from the stretcher 1. Step 2: At this time, the moving plate 31 moves, which drives the push-pull rod 42 to move. When the push-pull rod 42 moves, it drives the piston 43 to move. When the piston 43 moves, the gas in the air chamber 4 is delivered to the airbag 44 through the push-pull rod 42. At this time, the airbag 44 inflates to protect the patient's arms and legs.

[0023] In summary, in this embodiment, the multi-functional stretcher used for transferring critically ill patients utilizes a motor 6. The motor 6, when activated, facilitates the rotation of the rotating column 92. When the rotating column 92 rotates, it drives the gear 71 to rotate. The gear 71 then moves the rack 7, which in turn moves the base rod 72 and the base column 73, thereby moving the moving plate 31. The moving plate 31 then moves the lifting rod 3, allowing it to be moved into the stretcher 1 for storage. This storage of the lifting rod 3 when the stretcher is not in use reduces the risk of damage from impacts and minimizes the space occupied by the lifting rod 3. The base legs 11 provide support for the stretcher 1. The casters 17 facilitate patient transport by moving the stretcher. The connecting rod 13 supports the support plate 16. The connecting column 14 supports the first connecting plate 15. The support ring 2, support rod 21, and lifting plate 22 work together to support the motor 6 and lifting ring 9. The motor frame 61 and base frame 62 work together to support the motor 6. The lifting ring 9 and side rod 91 work together to support the rotating column 92, which is rotatably connected to the support frame via bearings. The lifting ring 9, through the sliding connection of the guide ring 84 and the guide rod 8, facilitates the guiding and limiting of the moving plate 31. The connecting ring 83, in cooperation with the connecting block 81, facilitates the support of the guide rod 8. The lifting rod 3 facilitates the transport of the stretcher 1. The anti-slip pad increases the friction of the lifting rod 3. The base rod 72 and base column 73 facilitate the support of the rack 7. The second connecting plate 5, support column 51, lifting frame 52, and lifting rod 53 facilitate the support of the air chamber 4. The air chamber 4, air pipe 41, push-pull rod 42, piston 43, and airbag 44 are all included. The motor 6... The start-up mechanism facilitates the rotation of the rotating column 92. When the rotating column 92 rotates, it drives the gear 71 to rotate. When the gear 71 rotates, it drives the rack 7 to move. When the rack 7 moves, it drives the moving plate 31 to move, removing the lifting rod 3 from the stretcher 1. At this time, the movement of the moving plate 31 drives the push-pull rod 42 to move. When the push-pull rod 42 moves, it drives the piston 43 to move. When the piston 43 moves, it delivers the gas in the air chamber 4 to the airbag 44 through the push-pull rod 42. At this time, the airbag 44 inflates, which can protect the patient's arms and legs, preventing the patient's arms and legs from colliding with the side frame 12 and causing secondary injuries, thus improving the safety of the stretcher.
