[0020] The technical solutions of 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.

[0021] Example 1, such as Figures 1 to 5 As shown, a multifunctional spinal cord injury rehabilitation mesh treatment bed according to an embodiment of the present invention includes a bed body 1, on which a flexible mesh 11 is welded. The flexible mesh 11 has multiple mesh holes 111, and a mattress 12 is laid on the flexible mesh 11. A massage mechanism and a drive mechanism are fixedly installed on the bed body 1. Specifically, the massage mechanism includes a pair of sliding boxes 2, the upper end face of which is flush with the lower end face of the flexible mesh 11. Multiple massage rollers 21 are rotatably connected to the sliding boxes 2, and the massage rollers 21 protrude from the upper end face of the sliding boxes 2. The drive mechanism includes a pair of sliding rods 3, which are symmetrically fixedly connected to the bed body 1. A pair of first through holes 201 are opened on the sliding boxes 2, and the sliding boxes 2 are slidably connected to the pair of sliding rods 3. During the sliding of the pair of sliding boxes 2 on the sliding rods 3, the massage rollers 21 come into contact with the flexible mesh 11. As the sliding boxes 2 slide on the sliding rods 3, the massage rollers 21 roll on the lower end face of the flexible mesh 11 and squeeze the flexible mesh 11.

[0022] Specifically, the flexible mesh 11 can effectively reduce the probability of pressure ulcers in patients. The drive mechanism is activated periodically, causing the sliding box 2 to slide back and forth on the slide rod 3. During the sliding process of the sliding box 2, the flexible mesh 11 is squeezed upwards by the massage roller 21. As the position of the massage roller 21 changes, the position of the protrusion of the flexible mesh 11 also changes. After the flexible mesh 11 protrudes, it transmits pressure to the mattress 12, causing the mattress 12 to also deform and protrude, thereby achieving a massage of the patient's back and leg muscles.

[0023] Preferably, mounting plates 31 are welded to both ends of the slide rod 3. Bolts are provided on the mounting plates 31. The mounting plates 31 are installed on the bed 1 by bolts. The installation method is simple and reliable and easy to disassemble.

[0024] like Figure 3 , Figure 7 and Figure 8 As shown, in this embodiment, the drive mechanism includes a motor 32, which is welded to the bed 1. A rotating plate 33 is welded to the shaft of the motor 32, and a pair of transmission plates 34 are rotatably connected to the rotating plate 33. The end of the transmission plate 34 away from the rotating plate 33 is rotatably connected to the slide box 2. Specifically, a pair of second hinge posts 331 are welded to the rotating plate 33, and a fourth through hole 3401 matching the second hinge posts 331 is opened on the transmission plate 34. The transmission plate 34 is sleeved on the second hinge posts 331 through the fourth through hole 3401, and the second hinge posts 331 are rotatably connected within the fourth through hole 3401. A first hinge post 28 is welded to the slide box 2, and a fifth through hole 3402 matching the first hinge post 28 is opened on the transmission plate 34. The end of the transmission plate 34 away from the rotating plate 33 is sleeved on the fifth through hole 3402, and the first hinge post 28 is rotatably connected within the fifth through hole 3402. When motor 32 is started, its shaft drives rotating plate 33 to rotate clockwise. During this process, rotating plate 33 pulls transmission plate 34, causing a pair of sliding boxes 2 to slide on sliding rod 3. As motor 32 rotates, the pair of sliding boxes 2 move closer together until they are in contact. After they are in contact, motor 32 rotates counterclockwise, and the pair of sliding boxes 2 move away from each other. In use, the running time of motor 32 is controlled according to the patient's injury, thereby controlling the duration and frequency of massage.

[0025] It should be noted that the forward and reverse rotation of motor 32 is achieved by changing the direction of the current applied to the stator winding, thereby changing the direction of the rotor rotation. The principle is the same as that of an air conditioner compressor or an electric bicycle, and it is existing technology.

[0026] like Figures 2 to 5As shown, due to the need to protect the patient's bones, the height of the massage roller 21 protruding from the upper surface of the sliding box 2 is limited. When the mattress 12 is laid down, the massage force of the massage roller 21 on the patient will be absorbed and reduced. Furthermore, the massage roller 21 is provided with two rows of protruding posts 22, which are symmetrically and fixedly connected to the massage roller 21. The height of each protruding post 22 is greater than the thickness of the flexible mesh 11, and the distance between each pair of protruding posts 22 matches the distance between the two rows of mesh holes 111. Specifically, as the massage roller 21 rolls on the lower surface of the flexible mesh 11, the protruding posts 22 penetrate the mesh holes 111 and protrude from the flexible mesh 11, increasing the massage force applied to the patient's muscles. This allows the massage force to act on deep muscle fibers, such as the erector spinae muscles in the back and the quadriceps muscles in the legs, thereby relieving chronic muscle tension and fascial adhesions, reducing the probability of muscle spasms in the patient, and further improving the massage effect.

[0027] Preferably, the protruding post 22 is a magnetic post, and the magnetic field strength of the magnetic post can have certain benefits for muscle tissue, such as relieving chronic soreness and repairing muscle damage.

[0028] It is worth noting that since the massage roller 21 protrudes from the slide box 2, the protruding massage roller 21 can cause discomfort to the patient when lying on the mattress 12. Furthermore, the slide box 2 is provided with a lifting component, which can lower the massage roller 21 into the slide box 2 or push the massage roller 21 out of the slide box 2.

[0029] Specifically, the lifting assembly includes a pair of wing plates 23 and an air pump 25. The pair of wing plates 23 are symmetrically welded to the side walls of the sliding box 2. An air box 24 is welded to the wing plates 23, and the air box 24 has a second air groove 2401 and a third air groove 2402, which are connected. A piston block 242 is slidably connected within the third air groove 2402, and a lifting block 241 is integrally formed on the piston block 242. The lifting block 241 passes through the air box 24 and is slidably connected to it. A fixing rod 27 is welded to the pair of lifting blocks 241. A waist-shaped hole 202 is formed on each opposite side wall of the sliding box 2, and the fixing rod 27 passes through the waist-shaped hole 202 and is slidably connected within it. The massage roller 21 is rotatably connected to the fixing rod 27. A pair of air pumps 25 are welded to the lower end face of the slide box 2. A first tube 26 is welded to the air pump 25. A second tube 261 is welded to the first tube 26. The end of the second tube 261 away from the first tube 26 is welded to the air box 24. The second tube 261 is connected to the second air groove 2401. A solenoid valve 262 is provided on the second tube 261.

[0030] Specifically, when a massage is needed for the patient, the air pump 25 is activated. The air pump 25 injects pressurized air into the second air groove 2401, which pushes the piston block 242 upward. After the piston block 242 is pushed upward, it lifts the massage roller 21 in the slide box 2, causing it to exert pressure on the flexible mesh 11. After the massage is finished, the solenoid valve 262 is opened, and the air in the second air groove 2401 and the third air groove 2402 is expelled. Under the action of gravity, the piston block 242 slides downward, and the massage roller 21 can descend into the slide box 2, ensuring the patient's comfort on the mattress 12.

[0031] The technical solutions described in the above embodiments of this application have at least the following technical effects or advantages: Compared with the prior art, in this embodiment, the flexible mesh 11 can reduce the pressure on the patient's body and lower the probability of pressure ulcers. Furthermore, during the sliding of the slide box 2 on the slide bar 3, while the massage roller 21 rolls and squeezes the flexible mesh 11, the protrusions 22 penetrate the mesh holes 111 to enhance the massage intensity on the patient's muscles, thereby effectively massaging and relaxing the patient's back muscles, reducing the frequency of muscle spasms, preventing muscle necrosis, and providing a guarantee for subsequent treatment.

[0032] Example 2: Considering that during use, patients lie on the mattress 12 for extended periods, resulting in prolonged pressure on the patient's back skin. The lack of breathability prevents sweat evaporation, keeping the skin moist and significantly reducing its tolerance. This ultimately leads to persistent ischemia and hypoxia, gradually causing skin redness and damage. In severe cases, the damage can penetrate into muscles and bones, forming ulcers that are difficult to heal. To address the above technical problems, this application proposes the following technical solution: like Figures 2 to 6 As shown, the fixed rod 27 has a ventilation cavity 2701 inside, and connecting pipes 271 connected to the ventilation cavity 2701 are welded to both ends of the fixed rod 27. Multiple connecting pipes 271 are connected to the first pipe body 26. A third through hole 2702 is provided on the fixed rod 27, and a second through hole 2101 matching the third through hole 2702 is provided on the massage roller 21. A first air groove 2201 and an air jet hole 2202 are provided on the protrusion 22.

[0033] Specifically, during the massage of the patient, the air pump 25 continuously supplies air into the ventilation chamber 2701. As the massage roller 21 rotates on the fixed rod 27, the second through hole 2101 and the third through hole 2702 will continuously align. When the second through hole 2101 and the third through hole 2702 are aligned, the air in the ventilation chamber 2701 can enter the first air groove 2201 from the second through hole 2101 and finally be ejected from the jet hole 2202. The ejected air blows through the mattress 12 onto the patient's back to circulate air.

[0034] Furthermore, the air jet 2202 is formed on the side wall of the protrusion 22, and the opening of the air jet 2202 faces the end away from the massage roller 21. The air jet 2202 formed on the side wall of the protrusion 22 can prevent it from being blocked by the mattress 12, ensuring the air jet effect while also expanding the air jet area.

[0035] Furthermore, the cross-section of the jet hole 2202 is conical, and the opening area of ​​the jet hole 2202 gradually decreases from the position away from the first air groove 2201, which can increase the air pressure ejected from the jet hole 2202 and facilitate the airflow through the mattress 12.

[0036] Preferably, during massage of the patient, the air pump 25 is connected to an oxygen tube at its air inlet, causing the jet nozzle 2202 to spray oxygen. Oxygen can accelerate blood circulation, help excrete metabolic waste, relieve muscle tension caused by hypoxia-induced fatigue, and improve the massage effect.

[0037] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: Compared with the prior art, in this embodiment, while massaging the patient, air is blown on the patient's back to accelerate the evaporation of sweat from the patient's back skin, making the skin dry, improving the skin's tolerance, ensuring the patient's skin's continuous blood and oxygen supply capacity, and preventing the patient's skin from being damaged.

[0038] Example 3: To improve the breathability of the mattress 12 and further protect the patient's skin, this application proposes the following technical solution, specifically: like Figure 1 and Figure 2 As shown, the interior of the mattress 12 has a honeycomb structure, which allows the airflow blown into the mattress 12 to be evenly dispersed and discharged.

[0039] Furthermore, a silicone layer 13 is adhered to the mattress 12, and the silicone layer 13 has multiple micropores 131. The silicone layer 13 is soft and delicate, with low friction when in contact with the skin, making it less likely to cause redness, swelling, itching, or other discomfort. Moreover, the silicone layer 13 is not easily deformed or worn, and daily cleaning only requires simple wiping or washing with water. It is also less prone to bacterial growth, indirectly ensuring hygiene and reducing the health risks associated with bacterial contact. The micropores 131 ensure airflow.

[0040] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: Compared with the prior art, in this embodiment, the mattress 12 can make the airflow spray evenly on the patient's skin surface, improve the massage effect on the patient's muscles and make all parts of the patient's skin in contact with the mattress 12 dry.

[0041] Obviously, the above-described embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include these modifications and variations.
