[0002] The nursing problems of the elderly in the aging society due to paralysis, cerebral hemorrhage and other diseases that require long-term bedridden have become a heavy burden for many families. Long-term bedridden patients are extremely prone to bedsores under the influence of physical factors such as temperature, pressure, and humidity. Most bedsores are caused by lying in bed for a long time without changing positions frequently, resulting in ischemia due to skin compression; especially patients with malnutrition and those with paralyzed limbs accompanied by sensory disorders are more likely to occur. Once bedsores occur, they not only cause difficulties in nursing, but also affect the recovery of patients, and in severe cases, they can even endanger life.

[0003] Currently, the devices used for preventing bedsores are mainly turning beds and inflatable pads. Turning beds are relatively bulky and inconvenient to move, and are only suitable for use in hospitals. While the existing anti-bedsore air cushions are rather difficult to turn patients over, increasing the labor intensity of nursing staff, and at the same time, it is difficult to effectively prevent bedsores.

[0024] As a further solution of the present invention, two docking pipes 602 are connected through the bottom surface of the outer side wall of the first connecting pipe 600. A horizontal pipe 603 is connected through the bottom surface of the docking pipe 602. Third connecting pipes 605 are respectively connected through the two ends of the horizontal pipe 603 close to the housing 700, and second connecting pipes 604 are respectively connected through the two ends of the horizontal pipe 603 far from the housing 700. The two second connecting pipes 604 are respectively connected to two turning airbags 201 close to the housing 700, and the two third connecting pipes 605 are respectively connected to two turning airbags 201 far from the housing 700.

[0025] Through the provided second connecting pipe 604 and third connecting pipe 605, the air pumped by the air pump 703 can enter the corresponding turning airbag 201 from the second connecting pipe 604 and the third connecting pipe 605, so that the bottom pad 100 is propped up at a certain angle. By providing the second electromagnetic valve 606, the third electromagnetic valve 607, the fourth electromagnetic valve 608 and the fifth electromagnetic valve 609, after the turning airbag 201 is filled with air, the corresponding electromagnetic valve can be closed, so that the air in the turning airbag 201 will not overflow, and at the same time, different turning airbags 201 can be selectively operated to be inflated to meet the needs of different usage scenarios.

[0026] As a further solution of the present invention, a bottom plate 300 is provided on the bottom surface of the bottom pad 100. One side of the bottom plate 300 is movably connected with a rotating plate 301. A bottom opening 303 is formed on the bottom surface of the bottom plate 300. Four bottom columns 302 are fixed on the bottom surface of the bottom plate 300. A placement plate 304 is fixed between the four bottom columns 302. Four fixing blocks 400 are fixed on one side of the top surface of the placement plate 304. A threaded rod 401 is movably connected between two opposite fixing blocks 400. A synchronous pulley 402 is fixed on one side of the outer sidewall of the threaded rod 401. A synchronous belt 403 is movably connected between the two synchronous pulleys 402. A servo motor 404 is fixed on the top surface of the bottom plate 300. The output end of the servo motor 404 is fixed to one end of one of the threaded rods 401. The threaded rod 401 is movably connected with a first limiter 405 on the periphery. The top of the first limiter 405 is movably connected with a rotating rod 406. Two second limiters 407 are fixed on the bottom surface of the rotating plate 301. One end of the rotating rod 406 is movably connected with the corresponding second limiter 407.

[0027] By providing the threaded rod 401, the first limiter 405, the rotating rod 406 and the second limiter 407, the rotating plate 301 can rotate a certain angle, so that the patient can lean on it, avoiding the discomfort caused by lying for a long time. By providing the synchronous belt 403, the synchronous pulleys 402 and the servo motor 404, the two threaded rods 401 can rotate synchronously, avoiding the situation that the rotation speeds of the two threaded rods 401 are slightly different, resulting in the blockage of the movement of the first limiter 405.

[0028] As a further solution of the present invention, a guiding groove 408 is formed on one side surface of the first limiter 405. Two guiding rods 409 are fixed on one side of the top surface of the bottom plate 300. The guiding rods 409 are engaged in the guiding groove 408.

[0029] By providing the guiding rods 409 and the guiding groove 408, the position of the first limiter 405 can be limited, avoiding the situation that the first limiter 405 is inclined.

[0030] As a further solution of the present invention, a second connecting strip 106 is fixed on one side of the bottom pad 100. The second connecting strip 106 is fixed on the top surface of the rotating plate 301. A first connecting strip 105 is fixed on the other side of the bottom pad 100.

The bottom strip 506 and the engaging blocks 505 are distributed in a cross shape.

[0031] Through the provided engaging blocks 505, engaging openings 507, and bottom strips 506, the position of the bottom pad 100 on the side away from the second connecting strip 106 can be movably limited, thereby facilitating the movement of this side of the bottom pad 100.

[0032] As a further aspect of the present invention, L-shaped plates 500 are respectively fixed on the sides of the two first limiters 405 that are close to each other. A tension spring 501 is fixed on the side surface of the L-shaped plate 500 close to the servo motor 404. One end of the tension spring 501 is fixed with a mounting disc 502. A connecting rope 503 is fixed on one side surface of the mounting disc 502. Two pulleys 504 are fixed on one side of the bottom surface of the bottom plate 300. The connecting rope 503 passes through the corresponding pulley 504, and one end of the connecting rope 503 is fixed to one side of the corresponding bottom strip 506.

[0033] Through the provided pulleys 504 and connecting ropes 503, when the first limiter 405 moves, it can drive the connecting rope 503 to move. Furthermore, the connecting rope 503 can pull the first connecting strip 105 to move, such that the moving directions of the first limiter 405 and the first connecting strip 105 are opposite. Through the provided tension spring 501, when the first limiter 405 moves, the tension spring 501 can be stretched, and then the tensile force is applied to the connecting rope 503, such that after the rotating plate 301 rotates a certain angle, the connecting rope 503 can always pull the first connecting strip 105.

[0034] As Figure 2 shown, the two anti-side-slip airbags 200 on the rotating plate 301 are respectively the upper body left anti-side-slip airbag and the upper body right anti-side-slip airbag, and the two anti-side-slip airbags 200 on the bottom plate 300 are respectively the lower body left anti-side-slip airbag and the lower body right anti-side-slip airbag.

[0036] Among them, the upper body left anti-side-slip airbag and the upper body left turning airbag are staggeredly distributed, the upper body right anti-side-slip airbag and the upper body right turning airbag are staggeredly distributed, the lower body left anti-side-slip airbag and the lower body left turning airbag are staggeredly distributed, and the lower body right anti-side-slip airbag and the lower body right turning airbag are staggeredly distributed.

[0037] In summary: First, place the placement board 304 on the hospital bed and fix it. Then, plug the power cord 704 into the socket. After that, operate the display screen, and the display screen transmits the operation signal to the main control board 702. The main control board 702 controls the air pump 703 to start. The air pump 703 injects air into the first connecting pipe 600, and then into the bottom pad 100. Through the docking air pipe 103 and the air nozzle 104, it enters several main air bags 102. After that, the main control board 702 controls the first electromagnetic valve 601 and the air pump 703 to close, so that the main air bags 102 expand. The injection time is set in the touch screen 701, and the injection time can be selected to make the main air bags 102 expand to an appropriate degree. After that, the patient can lie on several main air bags 102. When the patient needs to turn left on the upper body, the medical staff operates the touch screen 701 to select the upper body left turning mode. The main control board 702 controls the fourth electromagnetic valve 608 to open and the air pump 703 to start. The air pump 703 injects air into the first connecting pipe 600, and then into the corresponding docking pipe 602 and the horizontal pipe 603. Finally, it enters the second connecting pipe 604 connected to the upper body left turning air bag, and then into the upper body left turning air bag, and through the connecting pipe 202 into the upper body left anti-side-slip air bag, so that the upper body left turning air bag and the upper body left anti-side-slip air bag are respectively injected with air and expand. At this time, the patient's upper body is lifted by the upper body left turning air bag at a certain inclination angle, and the upper body left anti-side-slip air bag blocks the patient's left side to prevent the patient from falling off the main air bag 102. After that, the fourth electromagnetic valve 608 is closed.

[0038] When the patient needs to turn right on the upper body, the medical staff operates the touch screen 701 to select the upper body right turning mode. The main control board 702 controls the fifth electromagnetic valve 609 to open and the air pump 703 to start. The air pump 703 injects air into the first connecting pipe 600, and then into the corresponding docking pipe 602 and the horizontal pipe 603. Finally, it enters the third connecting pipe 605 connected to the upper body right turning air bag, and then into the upper body right turning air bag, and through the connecting pipe 202 into the upper body right anti-side-slip air bag, so that the upper body right turning air bag and the upper body right anti-side-slip air bag are respectively injected with air and expand. At this time, the patient's upper body is lifted by the upper body right turning air bag at a certain inclination angle, and the upper body right anti-side-slip air bag blocks the patient's right side to prevent the patient from falling off the main air bag 102. After that, the fifth electromagnetic valve 609 is closed.

[0039] When the patient needs to turn over to the right in the lower body, the medical staff operates the touch screen 701 to select the lower body right turn-over mode. The main control board 702 controls the opening of the third electromagnetic valve 607 and the activation of the air pump 703. The air pump 703 injects air into the first connecting pipe 600, and then enters the corresponding docking pipe 602 and the horizontal pipe 603, and finally enters the third connecting pipe 605 connected to the lower body right turn-over airbag. Then it enters the lower body right turn-over airbag and enters the lower body right anti-side-slip airbag through the connecting pipe 202, causing the lower body right turn-over airbag and the lower body right anti-side-slip airbag to be inflated by injecting air respectively. At this time, the patient's lower body is lifted by the lower body right turn-over airbag at a certain inclination angle, and the lower body right anti-side-slip airbag blocks the patient's right side to prevent the patient from falling off the main airbag 102. Then the third electromagnetic valve 607 is closed.

[0040] When the patient needs to turn over to the left in the lower body, the medical staff operates the touch screen 701 to select the lower body left turn-over mode. The main control board 702 controls the opening of the second electromagnetic valve 606 and the activation of the air pump 703. The air pump 703 injects air into the first connecting pipe 600, and then enters the corresponding docking pipe 602 and the horizontal pipe 603, and finally enters the second connecting pipe 604 connected to the lower body left turn-over airbag. Then it enters the lower body left turn-over airbag and enters the lower body left anti-side-slip airbag through the connecting pipe 202, causing the lower body left turn-over airbag and the lower body left anti-side-slip airbag to be inflated by injecting air respectively. At this time, the patient's lower body is lifted by the lower body left turn-over airbag at a certain inclination angle, and the lower body left anti-side-slip airbag blocks the patient's left side to prevent the patient from falling off the main airbag 102. Then the second electromagnetic valve 606 is closed.

[0041] The temperature sensor 203 can monitor the temperature inside the main airbag 102 in real time, transmit it to the main control board 702, and finally display the temperature on the touch screen 701.

[0042] When the air pressure sensor 204 detects that the pressure inside the main airbag 102 is lower than the specified value, the air pressure sensor 204 transmits the pressure information to the main control board 702. The main control board 702 controls the opening of the first electromagnetic valve 601 and the air pump 703, and the air pump 703 injects air into the main airbag 102.

[0043] When the patient lies on the main airbag 102 and it is necessary to tilt the upper body of the patient, the servo motor 404 is started. The rotation of the servo motor 404 drives the rotation of the threaded rod 401 connected thereto. Through the transmission of the synchronous belt 403 and the synchronous pulley 402, the rotation of another threaded rod 401 is driven, thereby driving the movement of the two first limiters 405. The movement of the first limiter 405 pushes the rotating rod 406 to rotate, so that the rotating plate 301 is propped up at a certain angle. At the same time, when the first limiter 405 moves, it drives the L-shaped plate 500 to move. The movement of the L-shaped plate 500 drives the movement of the tension spring 501. The movement of the tension spring 501 drives the movement of the mounting disc 502. The movement of the mounting disc 502 drives the movement of the connecting rope 503. The movement of the connecting rope 503 drives the movement of the bottom strip 506. The movement of the bottom strip 506 drives the movement of the engaging block 505. The movement of the engaging block 505 drives the movement of the first connecting strip 105.
