[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1: Please refer to Figures 1-4 , a pressure - sensitive anti - bedsore care mattress. The main body of the mattress is composed of a number of bottom boxes 1 spliced together. The bottom boxes 1 are square, which is convenient for splicing. Specifically, as Figure 1 shown, T - shaped grooves 3 are opened in the middle of the four sides of each bottom box 1. In this way, through the H - shaped connecting plate, two adjacent bottom boxes 1 can be connected together. The splicing design is convenient for freely customizing the shape of the mattress according to the shape of the bed board, and is applicable to bed boards of different sizes.

[0021] In this embodiment, a soft pad 2 is provided on the top of the bottom box 1. The edge of the soft pad 2 is connected to the edge of the top opening of the bottom box 1, endowing the mattress with the due "soft" characteristic.

[0022] As Figure 3 shown, a support block 4 is movably arranged up and down at the top opening of the bottom box 1. A pressure sensor 5 is provided in the central area of the top of the support block 4, and this area is fixedly connected to the soft pad 2. Thus, when the support block 4 moves down, the middle part of the soft pad 2 can be sunken inwards, so that the mattress is partially suspended. In practical applications, through the pressure sensor 5, the magnitude of the pressure and the pressure - receiving time at the position of the bottom box 1 can be monitored. The central control computer automatically controls the support block 4 to move down according to the magnitude of the pressure and the pressure - receiving time, so that the pressed area can be suspended, effectively reducing the risk of bedsore. Especially in the high - pressure area, long - term pressure can be avoided, the compression on the skin and soft tissues can be reduced, and the occurrence of bedsore can be effectively prevented.

[0023] Therefore, in the present invention, the main body of the mattress is modularly designed. By the pressure sensors 5 monitoring the pressure changes at local positions in real time, the pressure distribution of the mattress can be dynamically adjusted, effectively reducing the local high - pressure area and preventing the occurrence of bedsore caused by long - term lying in bed. For the specific circuit structure and algorithm, those skilled in the art can build them according to actual needs, which is not the focus of protection of the present invention.

[0024] In the present invention, the movement of the support block 4 is realized by a motor. Specifically, as Figure 4 shown, a screw groove 9 is opened at the bottom of the support block 4. A screw rod 10 is screwed in the screw groove 9. The screw rod 10 is fixedly connected to the top end of the output shaft of the adjusting motor 11. The adjusting motor 11 is fixedly installed on the inner bottom wall of the bottom box 1. By rotating the screw rod 10 forward and backward, the adjusting motor 11 can drive the support block 4 to move up or down.

[0025] Embodiment 2: Please refer to Figures 1-7 , on the basis of Embodiment 1, in this embodiment, at least one top groove 6 (two are provided in the present invention) is opened at the top of the support block 4. The massager 7 is arranged in the top groove 6. When the support block 4 moves down, the massager 7 can selectively stay in place or move up, asFigure 3 As shown, the massager 7 is composed of six small balls with rods. The small balls are arranged in a ring, and the ends of the rods are connected at one point.

[0026] As Figure 4 shown, a relief groove 8 corresponding to the position of the top groove 6 is opened at the bottom of the soft pad 2 to facilitate the entry of the massager 7.

[0027] In this embodiment, when the support block 4 moves downward, the massager 7 can remain in place. Thus, at this time, the entire soft pad 2 is sunken so that the compressed part of the patient's body is suspended. In this embodiment, when the support block 4 moves downward, the massager 7 can also move upward and enter the relief groove 8. At this time, the middle part of the soft pad 2 is sunken, and the relief groove 8 bulges. Through the bulge at the relief groove 8 by the massager 7, a certain massage effect can be achieved, relieving the muscle tension and discomfort caused by the patient's long-term bed rest, promoting blood flow, and further reducing the occurrence probability of pressure sores.

[0028] In this embodiment, the soft pad 2 is soft and stretchable, can be deformed by being pulled by the support block 4, and can also be deformed by being pushed up by the massager 7.

[0029] Regarding the movement of the massager 7, specifically, as Figure 4 and Figure 5 shown, the massager 7 is connected to the rotating rod 16 through the connecting column 13. The rotating rod 16 passes through the rod groove 17 in the support block 4 and then is rotatably connected to the telescopic rod 21. The telescopic rod 21 is movably telescopically arranged on the fixed ring 12. The fixed ring 12 is fixedly installed on the inner bottom wall of the bottom box 1. Thus, by controlling whether the telescopic rod 21 extends or not, it can be controlled whether the massager 7 remains in place or moves upward for massage.

[0030] As Figure 6 shown, the bottom end of the connecting column 13 is fixedly connected with a movable block 14. The movable block 14 is vertically movably arranged inside the rotating rod 16 and is supported upward by the support spring 15. When the massager 7 moves upward, if it presses too tightly against the patient's body, it will reversely compress the support spring 15 through the movable block 14. Through the setting of the support spring 15, the massager 7 can automatically adapt to various parts of the patient's body.

[0031] In the present invention, the bottom end of the telescopic rod 21 is fixedly installed on the driven piston 22. The driven piston 22 is movably arranged in the piston groove and is supported downward by the lower support spring 23. It also includes an air chamber 24, which is opened inside the fixed ring 12 and is connected to the piston groove through a communicating pipe. An active piston 25 is vertically movably arranged in the air chamber 24. As Figure 5 and Figure 7, a support rod 26 is fixedly installed at the top of the active piston 25. A pressing plate 27 is movably arranged up and down inside the support rod 26. The bottom of the pressing plate 27 is supported by a vertical spring 28. The top of the pressing plate 27 is connected to the supporting block 4 through a pressing rod 29; When the supporting block 4 moves downward, it will also drive the active piston 25 to move downward through the pressing rod 29 and the support rod 26. When the active piston 25 moves downward, the air in the air chamber 24 is filled into the piston groove through the connecting pipe. The gas filled in the piston groove makes the driven piston 22 move upward. When the driven piston 22 moves upward, the massager 7 can be driven to move upward through the telescopic rod 21, the rotating rod 16 and the connecting column 13.

[0032] In this embodiment, an exhaust pipe 30 is further provided. One end of the exhaust pipe 30 is communicated with the connecting pipe, and the other end is communicated with a bottom groove 32 opened at the bottom of the bottom box 1. An electromagnetic valve 31 for controlling the on-off of the pipeline is provided on the exhaust pipe 30. If you don't want the massager 7 to move upward, just open the electromagnetic valve 31. After the electromagnetic valve 31 is opened, when the active piston 25 moves downward again, the air can be discharged through the exhaust pipe 30 and will no longer push the driven piston 22 upward.

[0033] In the present invention, as Figure 5 shown, a slider 18 is further fixedly installed on the inner wall of the rod groove 17. The slider 18 is slidably arranged in the vertical sliding groove 19 and the spiral sliding groove 20. The vertical sliding groove 19 and the spiral sliding groove 20 are opened on the outer wall of the rotating rod 16 one above the other and communicated with each other; When the supporting block 4 moves downward and the rotating rod 16 moves upward, the slider 18 slides in the vertical sliding groove 19. At this time, it is in the first half; until the active piston 25 moves to the lowest position and the driven piston 22 moves to the highest position, at this time the slider 18 is located at the intersection of the vertical sliding groove 19 and the spiral sliding groove 20; As the supporting block 4 continues to move downward, the pressing rod 29 will compress the vertical spring 28 through the pressing plate 27, and the rotating rod 16 can no longer move upward. At this time, as the supporting block 4 continues to move downward, the slider 18 will move in the spiral sliding groove 20. Through the movement of the slider 18 in the spiral sliding groove 20, the rotating rod 16 can be driven to rotate, and then the connecting column 13 and the massager 7 are driven to rotate. Through the rotation of the massager 7, its massage effect can be further improved.

[0034] Embodiment Three: Please refer to Figure 4 and Figure 5 , on the basis of Embodiment One and Embodiment Two, in this embodiment, a wing ring 38 is fixedly installed on the outer wall of the supporting block 4. The bottom of the wing ring 38 is connected with a moving plug 34 through a connecting rod 35. The moving plug 34 is movably arranged in an inner cavity 33 formed inside the fixed ring 12; As Figure 4As shown, a one-way air outlet pipe 37 is provided at the top of the inner cavity 33. A one-way air inlet pipe 36 is connected to the side of the top end of the inner cavity 33. The other end of the air inlet pipe 36 is open at the bottom groove 32. In addition, a plurality of ventilation holes are evenly formed in the edge of the soft pad 2. When the support block 4 moves downward, the moving plug 34 is also driven to move downward through the connecting rod 35. When the moving plug 34 moves downward, external air is inhaled into the inner cavity 33 through the air inlet pipe 36. When the support block 4 moves upward, the external air in the inner cavity 33 can be discharged through the air outlet pipe 37, and the discharged air finally discharges from the ventilation holes, so as to enhance the ventilation effect of the mattress and further avoid the occurrence of pressure sores.
