At the same time, the support mechanism 3 and the support frame 1 can be used to adjust the support to different positions of the patient, thereby improving the practicality of the overall device.

[0032] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] Example 1:

[0034] Please refer to Figure 1 、 Figure 2, a pressure sore prevention device, which includes a support frame 1, both ends of the support frame 1 are fixedly connected with a baffle 2, the lower end of the support frame 1 and a position between the two baffles 2 is provided with a base 8, both ends of the base 8 are respectively fixedly connected to the baffles 2 at both ends, a support plate 10 is provided between the support frame 1 and the base 8, both ends of the support plate 10 are fixedly connected with a second fixed block 14, the upper end of the second fixed block 14 is provided with a limiting block 13, the lower end of the limiting block 13 is fixedly connected with a guide rod 11, the end of the guide rod 11 away from the limiting block 13 is fixedly connected with a first fixed block 12, one side of the first fixed block 12 is fixedly connected to the base 8, the first fixed block A second fixed block 14 is slidably connected between 12 and the limit block 13 and located on the outside of the guide rod 11. One side of the second fixed block 14 is fixedly connected to the support plate 10. The middle part of the upper end of the base 8 is fixedly connected to the electric telescopic rod 9. The telescopic end of the upper end of the electric telescopic rod 9 is fixedly connected to the middle part of the lower end of the support plate 10. A plurality of second slots 7 are provided at the upper end of the support frame 1, and a first slot 4 is provided in the middle part of the upper end of the support plate 10. A rotating mechanism 6 is provided inside the first slot 4, and a moving mechanism 5 is also provided inside the first slot 4. Support mechanisms 3 corresponding to the second slots 7 are provided at the upper end of the support plate 10 and at positions corresponding to the plurality of second slots 7.

[0035] The second support members 14 on both sides are driven by the second support members 14 to slide on the guide rods 11, thereby guiding and limiting the movement of the support members 10. When the support members 10 move upward, the support members 10 can push the second support members 3 to plug into the second notches 7, and then the support members 3 and the second notches 7 are plugged into the upper end of the support frame 1, so that the patient can lie on the support frame 1. In order to prevent the patient from maintaining a certain action and causing pressure sores on the body that is always under pressure, the support members 10 can be guided to move upward. The electric telescopic rod 9 can be started again, and the electric telescopic rod 9 pushes the support plate 10 to move upward. When the support plate 10 moves upward, the support plate 10 pushes multiple support mechanisms 3 to extend from the position of the second slot 7 to the upper end of the support frame 1, and then multiple support mechanisms 3 can be used to support different positions of the patient to prevent the occurrence of pressure sores. After the support mechanism 3 supports the patient for a long time, the electric telescopic rod 9 can be started to drive the support plate 10 to move down, and then the descending support plate 10 drives multiple support mechanisms 3 to move down to the inside of the second slot 7 and make the support mechanism 3 lower than the surface of the support frame 1, so that other positions of the patient can be supported by the support frame 1 to avoid the occurrence of pressure sores caused by long-term pressure.

[0036] Example 2:

[0037] The pressure sore prevention device provided in Example 1 is further optimized. Specifically, Figure 2 - Figure 5 As shown, the support mechanism 3 includes a support rod 15, which corresponds to the second slot 7. The support rod 15 is plugged into the second slot 7. The middle of the lower end of the support rod 15 is fixedly connected to a first fixed rod 16, and both ends of the lower end of the support rod 15 are provided with connecting components 17.

[0038] Specifically, the connecting assembly 17 includes a fixed column 18, the lower end of the fixed column 18 is fixedly connected to the support plate 10, a third slot 19 is opened in the middle of the upper end of the fixed column 18, and a connecting rod 21 is slidably connected inside the third slot 19. The upper end of the connecting rod 21 extends to the outside of the upper end of the fixed column 18 and is fixedly connected to the support rod 15.

[0039] Furthermore, one end of the connecting rod 21 away from the support rod 15 is located inside the third slot 19. In order to prevent the connecting rod 21 from sliding out of the third slot 19, sliders 22 are fixedly connected on both sides of one end of the connecting rod 21 located inside the third slot 19. Slide grooves 20 are provided on both sides of the inside of the third slot 19, and the sliders 22 are slidably connected to the slide grooves 20.

[0040] Specifically, the rotating mechanism 6 includes a motor 24, which is fixed at the middle position of one end of the first slot 4. The output end of the motor 24 is fixedly connected to a screw 23, and one end of the screw 23 away from the motor 24 is rotatably connected to the other end inside the first slot 4.

[0041] Specifically, the moving mechanism 5 includes a connecting block 26 , which is located inside the first notch 4 , is slidably connected to the first notch 4 , is threadedly connected to the screw 23 , and the upper end of the connecting block 26 is fixedly connected to the second fixing rod 25 .

[0042] Through the above structural design, it can be seen that when the patient is supported by multiple supporting mechanisms 3, the heights of the multiple supporting mechanisms 3 can be adjusted differently by cooperating with the moving mechanism 5 and the rotating mechanism 6. After the multiple supporting mechanisms 3 support the patient, the motor 24 can be started, and then the output end of the motor 24 drives the screw 23 to rotate inside the first notch 4. The rotation of the screw 23 can drive the connecting block 26 to move inside the first notch 4. The movement of the connecting block 26 can drive the second fixing rod 25 to move. The movement of the second fixing rod 25 can make the second fixing rod 25 move. When passing under the first fixing rod 16, the corresponding first fixing rod 16 can be squeezed by the second fixing rod 25. When the first fixing rod 16 is squeezed, the second fixing rod 25 pushes the first fixing rod 16 to move upward. When the first fixing rod 16 moves upward, the first fixing rod 16 pushes the support rod 15 to move upward. The upward moving support rod 15 can support a part of the patient's body to a higher height. At the same time, when the support rod 15 moves upward, the support rod 15 can drive the connecting rods 21 at both ends to move upward, and then the connecting rod 21 drives the slider 22 to slide upward inside the slide groove 20.
