[0002] A vacuum negative pressure immobilization mat is a medical device that uses negative pressure to fix body position and relieve pressure. It typically consists of a bag, foam particles, and an air nozzle. It utilizes negative pressure technology to create a low-pressure environment, thereby promoting blood circulation and cell regeneration, reducing pain, and accelerating wound healing. However, existing vacuum negative pressure immobilization mats require the user to lie flat on them, which can cause discomfort due to the lack of head support. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a vacuum negative pressure fixing pad with automatic vacuum forming, which solves the problem that in the process of using existing vacuum negative pressure fixing pads, users need to lie flat on the vacuum negative pressure fixing pad, but due to the lack of support for the user's head, it is very uncomfortable for the user.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a vacuum negative pressure fixing pad with automatic vacuum forming, comprising a vacuum negative pressure fixing pad body, a fixing plate fixedly connected to the vacuum negative pressure fixing pad body, two boxes fixedly connected to the fixing plate, two fixing rods fixedly connected inside the boxes, a movable plate slidably connected through the two fixing rods, a connecting strip fixedly connected to the top of the movable plate, two connecting strips, and a connecting plate fixedly connected between the two connecting strips;

[0005] A rubber pad is fixedly connected to the top of the connecting plate, two telescopic rods are fixedly connected to the bottom of the movable plate, a movable plate is fixedly connected to the bottom of the two telescopic rods, a V-shaped strip is fixedly connected to the bottom of the movable plate, a spring is sleeved on the telescopic rod, and a fixing strip is fixedly connected to the bottom of the inner wall of the box, with several V-shaped grooves opened on the fixing strip.

[0006] As a further embodiment of this utility model: one end of the spring is fixedly connected to the bottom of the movable plate, and the other end of the spring is fixedly connected to the top of the movable plate.

[0007] As a further embodiment of this utility model: the bottom of the vacuum negative pressure fixing pad body is fixed and connected to an air inlet pipe, and a support plate is fixedly connected to one of the boxes.

[0008] As a further embodiment of this utility model: an air pump is fixedly connected to the top of the support plate, and the end of the air inlet pipe away from the vacuum negative pressure fixing pad body is fixed to the air pump.

[0009] As a further embodiment of this utility model: an air outlet pipe is fixed and connected to one side of the air pump, and the air inlet pipe is connected to the air pump.

[0010] As a further embodiment of this utility model: the connecting plate is located on top of the fixed plate, and the movable plate is located inside the box.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This vacuum negative pressure fixing pad features automatic vacuum forming. It incorporates a rubber pad, V-groove, movable plate, spring, and V-shaped strip. When the position of the rubber pad needs adjustment, pushing the connecting plate moves the connecting strip and movable plate. The movable plate then moves the telescopic rod, movable plate, and V-shaped strip. Because both the V-shaped strip and V-groove are designed with inclined surfaces, when the V-shaped strip moves on the V-groove, the inclined surface pushes it upwards, causing it to move a certain distance. The V-shaped strip then moves the movable plate upwards and compresses the spring. When the rubber pad is adjusted to the appropriate position, the V-shaped strip is located inside one of the V-grooves, and the spring... In its original length state, the spring provides resistance to the upward movement of the V-shaped strip, ensuring that the V-shaped strip remains stably positioned inside the V-groove. The rubber pad, when moving, needs to overcome the resistance of the spring. Therefore, the spring provides a certain limiting effect on the rubber pad, ensuring its precise position. This vacuum negative pressure fixing pad supports the user's head through the rubber pad, improving user comfort. The position of the rubber pad can be adjusted according to the user's head size, ensuring its precision and preventing accidental movement. Users do not need to readjust it for subsequent uses, enhancing ease of use.

[0013] This vacuum negative pressure fixing pad features automatic vacuum forming. It is equipped with an inlet pipe, an air pump, and an outlet pipe. When vacuum forming is required, the air pump is activated to extract air from inside the pad. The air enters the inlet pipe and the air pump, and finally exits through the outlet pipe, thus completing the automatic vacuum forming process. This automatic vacuum forming ensures the normal operation of the vacuum negative pressure fixing pad without requiring manual vacuuming, significantly reducing the workload of workers and guaranteeing the quality of the vacuum forming process.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-3 As shown, this utility model provides a technical solution: a vacuum negative pressure fixing pad with automatic vacuum forming, including a vacuum negative pressure fixing pad body 1, a fixing plate 2 fixedly connected to the vacuum negative pressure fixing pad body 1, two boxes 3 fixedly connected to the fixing plate 2, and two fixing rods 11 fixedly connected inside the boxes 3. Because of the fixing rods 11, when the moving plate 12 moves, the moving plate 12 will slide on the fixing rods 11. The fixing rods 11 play a role in supporting, limiting and guiding the moving plate 12, improving the stability and accuracy of the moving plate 12. The moving plate 12 is slidably connected through the two fixing rods 11. An air outlet pipe 7 is fixed and connected to one side of the air pump 5, and an air inlet pipe 6 is connected to the air pump 5.

[0020] Two connecting strips 8 are fixedly connected to the top of the movable plate 12. A connecting plate 9 is fixedly connected between the two connecting strips 8. The connecting plate 9 is located on top of the fixed plate 2. The movable plate 12 is located inside the box body 3. A rubber pad 10 is fixedly connected to the top of the connecting plate 9. Two telescopic rods 15 are fixedly connected to the bottom of the movable plate 12. Because of the telescopic rods 15, the telescopic rods 15 connect the movable plate 17 and the movable plate 12, which can ensure the stability of the movable plate 17. The telescopic rods 15 can also restrict the spring 16, preventing the spring 16 from bending excessively when compressed and causing deformation, thus ensuring the normal operation of the spring 16.

[0021] Two telescopic rods 15 are fixedly connected to the bottom of a movable plate 17. A V-shaped strip 18 is fixedly connected to the bottom of the movable plate 17. A spring 16 is sleeved on the telescopic rod 15. Because of the spring 16, the spring 16 will provide a certain resistance to the upward movement of the V-shaped strip 18, so that the V-shaped strip 18 can be stably located inside the V-groove 14. When the rubber pad 10 moves, it needs to overcome the resistance of the spring 16. Therefore, the spring 16 can have a certain limiting effect on the rubber pad 10, ensuring the accuracy of the position of the rubber pad 10. One end of the spring 16 is fixedly connected to the bottom of the movable plate 12, and the other end of the spring 16 is fixedly connected to the top of the movable plate 17. A fixing strip 13 is fixedly connected to the bottom of the inner wall of the box 3.

[0022] The fixing strip 13 has several V-shaped grooves 14. The bottom of the vacuum negative pressure fixing pad body 1 is fixed and connected to the air inlet pipe 6. A support plate 4 is fixedly connected to one of the boxes 3. An air pump 5 is fixedly connected to the top of the support plate 4. Because of the air pump 5, the vacuum negative pressure fixing pad body 1 can be automatically vacuumed and formed by starting the air pump 5, which can ensure the normal operation of the vacuum negative pressure fixing pad body 1 and eliminates the need for manual vacuuming, thereby greatly reducing the labor intensity of the staff and ensuring the quality of vacuuming. The end of the air inlet pipe 6 away from the vacuum negative pressure fixing pad body 1 is fixed to the air pump 5.

[0023] The working principle of this utility model is as follows:

[0024] When the position of the rubber pad 10 needs to be adjusted, pushing the connecting plate 9 moves the connecting strip 8 and the moving plate 12. The moving plate 12 then moves the telescopic rod 15, the movable plate 17, and the V-shaped strip 18. Since both the V-shaped strip 18 and the V-groove 14 are designed with inclined surfaces, when the V-shaped strip 18 moves on the V-groove 14, the inclined surface of the V-groove 14 pushes the V-shaped strip 18 upward, causing it to move a certain distance. The V-shaped strip 18 then moves the movable plate 17 upward and compresses the spring 16. When the rubber pad 10 is adjusted to the appropriate position, the V-shaped strip 18 is located inside one of the V-grooves 14, and the spring 16... In its original length state, the spring 16 provides a certain resistance to the upward movement of the V-shaped strip 18, allowing the V-shaped strip 18 to be stably located inside the V-groove 14. When the rubber pad 10 moves, it needs to overcome the resistance of the spring 16. Therefore, the spring 16 can limit the rubber pad 10 to a certain extent, ensuring the accuracy of the position of the rubber pad 10. When it is necessary to vacuum the vacuum negative pressure fixing pad body 1, the air pump 5 is started to extract the air from the vacuum negative pressure fixing pad body 1. The air enters the air inlet pipe 6 and the air pump 5, and is finally discharged from the air outlet pipe 7, thus completing the automatic vacuum forming of the vacuum negative pressure fixing pad body 1.
