[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0032] Refer to Figures 1 to 3 , a prone anti - pressure - sore protection pad, including a frame 1. The frame 1 has a rectangular frame 1 structure and is usually made of a strong metal material, such as aluminum alloy or stainless steel. Aluminum alloy material has the characteristics of light weight and corrosion resistance, while stainless steel is more durable. The four corners of the frame 1 are polished to be round to avoid scratching the user during use. A plurality of protection pad bodies 2 are fixedly connected to the top of the frame 1. The protection pad bodies 2 can be adjusted according to the body shape of the user to disperse the body pressure. Shells 3 are fixedly connected to the outer four corners of the left protection pad body 2. The shells 3 have a cylindrical hollow structure and are usually made of plastic material. The plastic shells 3 have the characteristics of light weight and low cost. A spring 4 is arranged inside the shell 3. The spring 4 is usually a spiral metal spring made of high - strength steel. The diameter and length of the spring 4 are selected according to the size of the shell 3 and the required supporting force. A limiting plate 5 is slidably connected inside the shell 3. The size of the limiting plate 5 is slightly smaller than the internal size of the shell 3 so that it can slide freely inside the shell 3;

[0033] The function of the limit plate 5 is to limit the compression stroke of the spring 4 and prevent the spring 4 from being damaged due to excessive compression. The top of the limit plate 5 is fixedly connected with a rubber rod 6. The rubber rod 6 is of a cylindrical structure and is made of soft rubber material. The diameter and length of the rubber rod 6 are selected according to actual requirements. The top of the rubber rod 6 is fixedly connected with a headrest pad 7. The headrest pad 7 prevents the head from directly contacting the protection pad body 2 and causing pressure sores. The adjacent sides of the two protection pad bodies 2 are rotatably connected with a rubber plate 9. The function of the rubber plate 9 is to connect the two protection pad bodies 2 so that they can rotate within a certain angle range to adapt to the body postures of different users. The surface of the rubber plate 9 is usually smoothed to make its rotation more smooth. On the front and back sides of the outside of the frame 1, there are fixedly connected with adjusting components for support. The adjusting component includes a fixed frame 12. Inside the fixed frame 12, there is fixedly connected with a connecting shaft 13. The function of the connecting shaft 13 is to provide rotational support for the rotating block 14 so that it can freely rotate inside the fixed frame 12. The surface of the connecting shaft 13 is usually smoothed to make its rotation more smooth. The outside of the connecting shaft 13 is rotatably connected with a rotating block 14. The outside of the rotating block 14 is fixedly connected with a support plate 15. The top of the middle protection pad body 2 is fixedly connected with a lumbar support pad 10. The function of the lumbar support pad 10 is to provide support for the user's waist and prevent the waist from directly contacting the protection pad body 2 and causing pressure sores.

[0034] Refer to Figures 3 to 5 , the top of the right protection pad body 2 is fixedly connected with a footrest pad 11. The position of the footrest pad 11 is relatively fixed and can provide stable support for the user's feet. The outside of the footrest pad 11 is in contact with the outside of the frame 1. Inside the lumbar support pad 10, there is a buffer layer 16. The bottom of the buffer layer 16 is fixedly connected with a tear-resistant layer 17. The bottom of the tear-resistant layer 17 is fixedly connected with a reinforcement layer 8. The material of the buffer layer 16 is gel. The gel has the characteristics of softness and good elasticity, can effectively relieve the pressure on the waist and provide comfortable support. When the buffer layer 16 is subjected to an external force, it will deform to a certain extent, thereby dispersing the pressure and protecting the waist from compression;

[0035] The material of the tear-resistant layer 17 is fiberboard, which has high strength and toughness and can effectively prevent the lumbar support pad 10 from being torn during use. The tear-resistant layer 17 has a flat sheet structure, and its thickness and strength are selected according to actual needs. The material of the reinforcement layer 8 is high-strength nylon, which has the characteristics of high strength, wear resistance, corrosion resistance, etc., and can provide additional strength and stability for the lumbar support pad 10. The outside of the tear-resistant layer 17 is arranged inside the lumbar support pad 10, the outside of the reinforcement layer 8 is arranged inside the lumbar support pad 10, the outside of the support plate 15 is rotatably connected to the inside of the fixing frame 12, the outside of the rotating block 14 is rotatably connected to the inside of the fixing frame 12, and one end of the spring 4 is fixedly connected to the outside of the limiting plate 5, and the other end of the spring 4 is fixedly connected to the inside of the housing 3. When an external force acts, the spring 4 will be compressed and elastically deformed to provide a certain supporting force.

[0036] Working principle: When the patient rests their head on the outside of the headrest pad 7, due to the external gravity, the headrest pad 7 can exert pressure on the rubber rod 6. Under the action of the rubber rod 6, the rubber rod 6 squeezes the spring 4 through the limiting plate 5, and then the spring 4 can be deformed, causing the spring 4 to be compressed inside the housing 3, thereby improving the comfort of the patient. By rotating the support plate 15, the support plate 15 can rotate around the connecting shaft 13 through the rotating block 14, and then the support plate 15 can be adjusted arbitrarily on the horizontal plane, and then the support for the patient's hand can be realized.

[0037] When the human body is in the prone position, the weight of the waist is transmitted to the reinforcement layer 8 and the tear-resistant layer 17 through the buffer layer 16. The buffer layer 16 is located in the innermost layer and is in direct contact with the human waist. Its main function is to provide soft support and buffering to reduce the pressure on the waist. When the human body is in the prone position, the buffer layer 16 can deform to a certain extent according to the shape and pressure of the waist, evenly disperse the pressure, and avoid excessive local pressure resulting in pressure sores. Through its own elastic deformation, the buffer layer 16 evenly disperses the pressure over a larger area, reducing local pressure. The reinforcement layer 8 is located between the buffer layer 16 and the tear-resistant layer 17. The function of the reinforcement layer 8 is to provide additional strength and stability to the lumbar support pad 10. It can prevent the lumbar support pad 10 from deforming excessively during use and maintain a certain shape, thereby better supporting the waist. At the same time, the reinforcement layer 8 can also share part of the pressure from the human body and reduce the burden on the buffer layer 16. The reinforcement layer 8 provides support and stability to the lumbar support pad 10 and prevents it from deforming excessively. The tear-resistant layer 17 is located in the outermost layer and mainly serves to protect the lumbar support pad 10. The tear-resistant layer 17 has high strength and wear resistance and can prevent the lumbar support pad 10 from being torn or damaged during use. It can withstand external friction and pulling forces and extend the service life of the lumbar support pad 10. The tear-resistant layer 17 protects the lumbar support pad 10 from external damage and ensures that it can play its role effectively for a long time. In this way, the three-layer structure cooperates with each other to jointly provide comfortable support and pressure sore prevention protection for the waist.
