[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the pressure injury wound care device adopts a new structural design, and the angle of the auxiliary plate can be changed by setting an angle adjustment component, thereby optimizing the comfort of the patient. A massage component is also provided, and when the massage component is working, the lower surface of the patient's legs can be massaged to relax the patient's muscles. In addition, a disinfection component is also provided to disinfect the left side of the bed board, so that there are fewer germs around the patient and safety is improved. The specific contents are as follows: (1) The device for the care of pressure injury wounds is used. When the patient maintains a posture for a long time and needs to change the posture, the motor can be started. When the motor is working, the push plate is driven to move to the middle position of the bed board through the long pin and the limit rod. At this time, the push plate pushes the long plate, so that the long plate pushes the auxiliary plate through the top plate, so that the auxiliary plate rotates around the fixed axis. Finally, the angle of the auxiliary plate is changed, making the patient more comfortable. Furthermore, during the movement of the push plate, the limit rod enables the push plate to move only in the horizontal direction, thereby ensuring safety, and during the movement of the long board, the limit column enables the long board to move only in the vertical direction, and the lower surface of the limit column is convex, thereby limiting the moving distance of the long board and ensuring stability; Furthermore, during use, fences can be connected on both sides of the bed board, so that the patient is safer during treatment and will not fall out of bed. At the same time, soft bags are set on the fences to improve the comfort of the fences, thereby preventing accidental injuries due to bumps. (2) The device for nursing pressure injury wounds, during the movement of the push plate, drives the connecting shaft to rotate through the connecting rod, the tooth block and the gear. When the connecting shaft rotates, it drives the fixed plate to rotate synchronously. When the fixed plate rotates, the second magnet will intermittently hit the first magnet. At this time, the movable plate will make reciprocating linear motion in the vertical direction under the action of the mutual repulsive magnetic force of the first magnet and the second magnet, the column and the reset spring. Then, the movable plate will knock the patient's legs through the massage rod, so that the patient's leg muscles relax and improve comfort. Furthermore, the second magnets are distributed at equal angles on the surface of the fixed plate, thereby accelerating the frequency of the reciprocating linear motion of the movable plate, improving the working efficiency of the massage rod, and ultimately optimizing the comfort of the patient; (3) The pressure injury wound care device, when the connecting rod moves, will drive the pressure plate to move synchronously. When the pressure plate moves to squeeze the airbag, the airbag will spray disinfectant mist through the auxiliary tube and nozzle, so that the disinfectant can disinfect the air around the patient's leg pressure sore, thereby improving safety; Furthermore, when the airbag sprays disinfectant through the auxiliary tube and the nozzle, the first one-way valve allows the disinfectant to move only from the airbag toward the nozzle, and when the connecting rod and the pressure plate move back, the airbag will inflate again. At this time, the airbag sucks the disinfectant inside the working box into the airbag through the feed pipe. In this process, the second one-way valve allows the disinfectant to move only from the working box to the inside of the airbag. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Embodiment 1: By setting the motor 3, the long pin 4 and the limit rod 5, the push plate 6 can make a reciprocating linear motion in the horizontal direction, and finally the auxiliary plate 11 can be rotated to change the angle of the auxiliary plate 11, so as to improve the comfort of the patient. Figure 1-Figure 5 As shown: It includes a bed board 1 and an external connecting plate 25, the lower surface of the bed board 1 is fixedly connected with a bracket, the lower surface of the bed board 1 is fixedly connected with a lower connecting plate 2, the surface of the lower connecting plate 2 is bolted with a motor 3, and the output end of the motor 3 is fixedly connected with a long pin 4; The external plate 25 is fixedly connected to the left side of the bed board 1, and the airbag 26 is bonded to the surface of the external plate 25, and the fixed shaft 10 is fixedly connected to the surface of the bed board 1, and the auxiliary plate 11 is sleeved and connected to the surface of the fixed shaft 10, and the working box 27 is fixedly connected to the surface of the external plate 25, and the feeding pipe 31 is placed inside the working box 27; A device for nursing a pressure injury wound, further comprising: The surface of the long pin 4 is fixedly connected with an angle adjustment component for adjusting the angle of the auxiliary plate 11, the lower surface of the bed board 1 is fixedly connected with a column 17, and the surface of the column 17 is provided with a massage component for massaging the patient's legs; The surface of the external connecting plate 25 is provided with a disinfection component for spraying disinfectant, and the angle adjustment component includes a push plate 6 threadedly connected to the surface of the long pin 4, and the surface of the lower connecting plate 2 is fixedly connected to a limiting rod 5, and the limiting rod 5 runs through the interior of the push plate 6.

[0020] The angle adjustment assembly also includes a limit column 9 fixedly connected to the lower surface of the bed board 1, and the surface of the limit column 9 is sleeved with a long board 7, and the limit column 9 is symmetrically distributed about the center of the long board 7, the lower surface of the long board 7 is inclined, and the lower surface of the long board 7 is fitted with the upper surface of the push plate 6, and the upper surface of the long board 7 is fixedly connected with a top plate 8, the lower surface of the limit column 9 is convex, the upper surface of the top plate 8 is fitted with the lower surface of the auxiliary board 11, and the surface of the auxiliary board 11 is convex, and the surface of the bed board 1 is concave.

[0021] During use, the patient maintains a posture for a long time, which leads to low comfort. When the posture needs to be changed, the motor 3 on the surface of the lower connecting plate 2 can be started. When the motor 3 is working, the push plate 6 is driven to move to the middle position of the bed board 1 through the long pin 4 and the limit rod 5. At this time, the push plate 6 pushes the long board 7, so that the long board 7 pushes the auxiliary board 11 through the top plate 8, so that the auxiliary board 11 rotates around the fixed axis 10 inside the bed board 1, and finally the angle of the auxiliary board 11 is changed to make the patient more comfortable. During the movement of the push plate 6, the limit rod 5 makes the push plate 6 move only in the horizontal direction to ensure safety. During the movement of the long board 7, the limit column 9 makes the long board 7 move only in the vertical direction, and the lower surface of the limit column 9 is convex, which limits the moving distance of the long board 7 and ensures stability.

[0022] Embodiment 2: Different from Embodiment 1, the massage component can be used to massage the patient's legs, thereby improving the patient's comfort. Figure 6-Figure 9 As shown: The massage assembly includes a connecting shaft 13 rotatably arranged on the lower surface of the bed board 1, a connecting rod 12 is fixedly connected to the surface of the push plate 6, and the connecting rod 12 is an inverted "L" shape when viewed from above, and the surface of the connecting rod 12 is fixedly connected to tooth blocks 14 at equal intervals, the surface of the connecting shaft 13 is fixedly connected to a gear 16 meshing with the tooth blocks 14, and the connecting shaft 13 is symmetrically distributed about the center of the bed board 1, and the surface of the connecting shaft 13 is fixedly connected to a fixing plate 15.

[0023] The upper surface of the fixed plate 15 is fixedly connected to a second magnet 23, and the second magnet 23 is distributed at equal angles on the upper surface of the fixed plate 15. The massage component also includes a movable plate 20 sleeved and connected to the surface of the column 17, and the lower surface of the movable plate 20 is fixedly connected to a first magnet 22, and the magnetic poles of the lower surface of the first magnet 22 are the same as the magnetic poles of the upper surface of the second magnet 23.

[0024] The lower surface of the column 17 is fixedly connected to a connecting plate 18, and the upper surface of the connecting plate 18 is fixedly connected to a return spring 19 which plays an elastic return role, and the other side of the return spring 19 is fixedly connected to the lower surface of the movable plate 20, and the upper surface of the movable plate 20 is fixedly connected to massage rods 21 at equal intervals.

[0025] During the movement of the push plate 6, the push plate 6 drives the connecting shaft 13 to rotate through the connecting rod 12, the tooth block 14 and the gear 16. When the connecting shaft 13 rotates, the fixed plate 15 is driven to rotate synchronously. When the fixed plate 15 rotates, the second magnet 23 will intermittently approach the first magnet 22. When the second magnet 23 approaches the first magnet 22, the movable plate 20 rises under the action of the repulsive magnetic force. At this time, the reset spring 19 is stretched, and when the second magnet 23 is away from the first magnet 22, the movable plate 20 moves back under the action of the reset spring 19. Repeat the above process, the movable plate 20 will make reciprocating linear motion in the vertical direction under the action of the repulsive magnetic force of the first magnet 22 and the second magnet 23, the column 17 and the reset spring 19, and then the movable plate 20 will knock the patient's legs through the massage rod 21 to relax the patient's leg muscles and improve comfort. The second magnets 23 are distributed at equal angles on the surface of the fixed plate 15, thereby accelerating the frequency of the reciprocating linear motion of the movable plate 20, improving the working efficiency of the massage rod 21, and finally optimizing the patient's comfort.

[0026] Embodiment 3: Different from Embodiment 2, the air at the left side of the bed board 1 (i.e., the patient's thigh position) can be disinfected by setting a disinfection component, thereby improving the safety when changing the pressure sore dressing. Figure 2 , Figure 6-Figure 10 As shown: The disinfection assembly includes a pressure plate 24 fixedly connected to the end of the connecting rod 12, and the disinfection assembly also includes a nozzle 28 fixedly connected to the surface of the external plate 25, and the lower surface of the nozzle 28 and the upper surface of the airbag 26 are fixedly connected with an auxiliary tube 29, and the surface of the auxiliary tube 29 is fixedly connected with a first one-way valve 30, the feed pipe 31 is fixedly connected to the airbag 26, and the surface of the feed pipe 31 is fixedly connected with a second one-way valve 32.

[0027] When the connecting rod 12 moves, it will drive the pressing plate 24 to move synchronously (such as Figure 2 and Figure 6As shown in the figure, when the pressing plate 24 moves to the left, it will eventually contact and squeeze the airbag 26. When the pressing plate 24 moves to squeeze the airbag 26, the airbag 26 will spray disinfectant mist through the auxiliary tube 29 and the nozzle 28, so that the disinfectant can disinfect the air around the patient's leg pressure sore, thereby improving safety. When the airbag 26 sprays the disinfectant through the auxiliary tube 29 and the nozzle 28, the first one-way valve 30 allows the disinfectant to move only from the airbag 26 to the nozzle 28. When the connecting rod 12 and the pressing plate 24 move back, the airbag 26 will expand again. At this time, the airbag 26 sucks the disinfectant inside the working box 27 into the airbag 26 through the feeding pipe 31. In this process, the second one-way valve 32 allows the disinfectant to move only from the working box 27 to the inside of the airbag 26. The first one-way valve 30 and the second one-way valve 32 ensure the stability of the flow of the disinfectant, and backflow will not occur.

[0028] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
