[0029] Please refer toFigure 1-6 , the present utility model provides an anti - bedsore air cushion with a massage function, including a bottom plate 100. A anti - bedsore air cushion 101 is fixed on the top surface of the bottom plate 100, and an air pump 102 is fixed on the bottom surface of the bottom plate 100. The output end of the air pump 102 is connected with a connecting pipe 103, and one end of the connecting pipe 103 is communicated with the anti - bedsore air cushion 101. On one side of the bottom surface of the bottom plate 100, there is a fixing plate 200. A plurality of sleeve columns 201 distributed in a circle are fixed on the top surface of the fixing plate 200. A first spring 202 is arranged in the sleeve column 201. A contact plate 206 is movably clamped in the sleeve column 201. A connecting rod 203 is fixed at the center of the top surface of the contact plate 206. The connecting rod 203 movably passes through the top surface of the sleeve column 201. A spherical limiting cover 204 is fixed on the top surface of the connecting rod 203. A rolling ball 205 is rotatably connected in the spherical limiting cover 204. A lifting component is arranged on one side of the bottom surface of the bottom plate 100.

[0030] Further, as Figure 5 shown, a circular limiter 300 is arranged on one side of the bottom surface of the bottom plate 100. A toothed ring 301 is rotatably connected in the circular limiter 300. The top of the inner side wall of the toothed ring 301 is fixed to the outer side wall of the fixing plate 200.

[0031] By arranging the circular limiter 300, the position of the toothed ring 301 can be movably limited, thereby facilitating the rotation of the fixing plate 200.

[0032] Further, as Figure 5 shown, the lifting component includes three electric push rods 401 distributed in a circle. The electric push rods 401 are fixed on one side of the bottom surface of the bottom plate 100. Three fixing blocks 400 distributed in a circle are fixed on the outer side wall of the circular limiter 300. The output end of the electric push rod 401 is fixed to the top surface of the corresponding fixing block 400.

[0033] By arranging the electric push rods 401, the fixing plate 200 can move up and down, thereby driving the rolling ball 205 to move up, so that the rolling ball 205 contacts the patient's back and massages the patient's back.

[0034] Further, as Figure 2 and Figure 4 shown, roller shafts 500 are respectively arranged on both sides of the bottom plate 100. Rotating shafts 502 are respectively fixed at both ends of the roller shafts 500. A breathable cloth 501 is connected between the outer side walls of the two roller shafts 500. A support frame 104 is fixed on the bottom surface of the bottom plate 100. Side rods 504 are respectively fixed at the top of the opposite two side surfaces of the outer side wall of the support frame 104. The rotating shafts 502 are movably connected to the corresponding side rods 504.

[0035] By providing the roller 500, the position of the breathable cloth 501 can be fixed. By providing the side rod 504, the position of the roller 500 can be rotationally limited, so that the breathable cloth 501 can move and always be in a tensioned state.

[0036] Further, as shown in Figure 4 Figure 5, a second gear 503 is fixed to the outer side wall of the rotating shaft 502. A rack 600 is arranged below the second gear 503. The rack 600 meshes with the second gear 503. A limiting strip 601 is fixed to the bottom surface of the rack 600. Two mounting rods 602 are respectively fixed to the opposite two side surfaces of the outer side wall of the bottom plate 100. Two positioning columns 603 are fixed to one side of the mounting rod 602. The positioning columns 603 are movably engaged with the limiting strip 601. An anti-falling strip 604 is fixed to one end of the two positioning columns 603.

[0037] By providing the rack 600, the second gear 503 can rotate. By providing the positioning columns 603 and the limiting strip 601, the position of the rack 600 can be movably limited.

[0038] The working process of this solution is as follows: When preventing bedsores from occurring on the patient's back, start the air pump 102. The air pump 102 pumps air into the anti-bedsore air cushion 101, so that the anti-bedsore air cushion 101 can support the patient and keep the air on the patient's back in a circulating state to prevent bedsores from occurring.

[0039] When massaging the patient's back, operate the PLC controller 402. The PLC controller 402 controls the three electric push rods 401 to start synchronously. The output end of the electric push rod 401 drives the upper part of the annular limiter 300, so that the rolling ball 205 contacts the patient's back. By controlling the upward movement distance of the electric push rod 401, the contact pressure between the rolling ball 205 and the patient's back can be adjusted. Then start the motor 303. The motor 303 rotates to drive the first gear 302 to rotate. The first gear 302 rotates to drive the toothed ring 301 to rotate. The toothed ring 301 rotates to drive the sleeve column 201 to rotate, and further makes the rolling ball 205 rotate. The rolling ball 205 rotates to massage the patient's back.

[0040] When the breathable cloth 501 is tensioned and the patient lies on the breathable cloth 501, when the two sides of the top surface of the breathable cloth 501 approach each other, the breathable cloth 501 moves at this time. The movement of the breathable cloth 501 drives the corresponding roller 500 to rotate, and then drives the second gear 503 to rotate. The rotation of the second gear 503 drives the rack 600 to move. The movement of the rack 600 further stretches the second spring 702, and at the same time, the second spring 702 on the other side is also stretched. At this time, the breathable cloth 501 extends out on the two rollers 500, so that the breathable cloth 501 is always in a tensioned state. When the patient gets off the anti-bedsore air cushion 101, the second springs 702 on both sides pull the rack 600 to move, and then the two rotating shafts 502 wind the excess breathable cloth 501 on the roller 500, so that the breathable cloth 501 is in a tensioned state.

[0041] According to the above working process, it can be seen that: by setting the annular limiter 300, the position of the toothed ring 301 can be movably limited. By setting the sleeve column 201, the contact plate 206, the first spring 202 and the connecting rod 203, the contact pressure exerted by the rolling ball 205 on the patient's back can be adjusted. By setting the electric push rod 401 and the first spring 202, the rolling ball 205 can contact the patient's back, and at the same time, the contact pressure exerted by the rolling ball 205 on the patient's back can be adjusted, thereby changing the massage strength on the patient's back. Through the rolling ball 205, when the fixing plate 200 rotates, it can massage the patient's back, so as to massage the patient's back, avoiding the situation that the patient's back aches and feels uncomfortable when lying on the anti-bedsore air cushion for a long time, and at the same time, the massage strength can be adjusted, improving the comfort of the patient's back massage.

[0042] By setting the breathable cloth 501, the breathable cloth 501 can be protected, avoiding the situation that the anti-bedsore air cushion 101 is punctured by sharp objects. By setting the roller 500, the second gear 503, the rack 600, the positioning column 603 and the second spring 702, the breathable cloth 501 is always in a tensioned state, so that the breathable cloth 501 can always protect the top surface of the anti-bedsore air cushion 101, avoiding the situation that the movement of the patient drives the breathable cloth 501 to move, resulting in a reduction in the protection performance of the anti-bedsore air cushion 101.

[0043] Further as Figure 4 shown, one end of the rack 600 is fixed with a side plate 700, one side surface of the side plate 700 is fixed with a moving column 701, the periphery of the moving column 701 is provided with a second spring 702, the other two opposite side surfaces of the outer side wall of the bottom plate 100 are respectively fixed with two stabilizing blocks 703, the positioning column 603 is correspondingly movably connected with the stabilizing blocks 703, one end of the second spring 702 is fixed with one side surface of the side plate 700, and the other end of the second spring 702 is fixed with one side surface of the stabilizing block 703.

[0044] Through the arranged moving column 701 and the second spring 702, the movement of the breathable cloth 501 can drive the movement of the rack 600, and further drive the movement of the moving column 701.

[0045] Furthermore, as shown in Figure 2 and Figure 5 As shown, a chassis 305 is fixed to the bottom surface of the annular limiter 300, a mounting plate 304 is fixed to the inner side wall of the chassis 305, a motor 303 is fixed to one side surface of the mounting plate 304, a first gear 302 is fixed to the output end of the motor 303, and the first gear 302 meshes with the toothed ring 301.

[0046] Through the arranged motor 303 and the first gear 302, the toothed ring 301 can rotate, and further the fixing plate 200 can rotate, so that the rolling ball 205 can massage the patient's back.

[0047] Furthermore, as shown in Figure 1 As shown, a PLC controller 402 is fixed to one side of the outer side wall of the support frame 104. The three electric push rods 401 are respectively electrically connected to the PLC controller 402, the motor 303 is electrically connected to the PLC controller 402, and the air pump 102 is electrically connected to the PLC controller 402.

[0048] Through the arranged PLC controller 402, the three electric push rods 401 can be started synchronously, and further drive the movement of the fixing plate 200.

[0049] In summary: When preventing the patient's back from getting bedsores, start the air pump 102. The air pump 102 pumps air into the anti-bedsore air cushion 101, so that the anti-bedsore air cushion 101 can support the patient, making the air on the patient's back in a circulating state and preventing bedsores from occurring.

[0050] When massaging the patient's back, operate the PLC controller 402. The PLC controller 402 controls the three electric push rods 401 to start synchronously. The output end of the electric push rod 401 drives the annular limiter 300 to move upward, so that the rolling ball 205 contacts the patient's back. By controlling the upward movement distance of the electric push rod 401, the contact pressure between the rolling ball 205 and the patient's back can be adjusted. Then start the motor 303. The motor 303 rotates to drive the first gear 302 to rotate. The first gear 302 rotates to drive the toothed ring 301 to rotate. The toothed ring 301 rotates to drive the sleeve column 201 to rotate, and further the rolling ball 205 rotates. The rolling ball 205 rotates to massage the patient's back.

[0051] When the breathable cloth 501 is tensioned and the patient lies on the breathable cloth 501, when the two sides of the top surface of the breathable cloth 501 approach each other, the breathable cloth 501 moves at this time. The movement of the breathable cloth 501 drives the corresponding roller 500 to rotate, and then drives the second gear 503 to rotate. The rotation of the second gear 503 drives the rack 600 to move. The movement of the rack 600 causes the second spring 702 to be further stretched. At the same time, the second spring 702 on the other side is also stretched. At this time, the breathable cloth 501 on the two rollers 500 extends, so that the breathable cloth 501 is always in a tensioned state. When the patient gets off the anti-bedsore air cushion 101, the second springs 702 on both sides pull the rack 600 to move, and then the two rotating shafts 502 wind up the excess breathable cloth 501 on the roller 500, so that the breathable cloth 501 is in a tensioned state.

[0052] The anti-bedsore air cushion 101, the air pump 102, the motor 303, the electric push rod 401 and the PLC controller 402 can all be purchased on the market. They are mature technologies in this field and have been fully disclosed. Therefore, they will not be repeated in the specification.
