Description

Technical Field

[0001] The utility model relates to the technical field of anti-bedsore mattresses, in particular to an anti-bedsore mattress with a turning over function. Background Art

[0002] Bedsores, also known as pressure ulcers or bedsores, are caused by long-term compression of local tissues in the human body, resulting in continuous ischemia, hypoxia, and malnutrition, which lead to tissue ulceration and necrosis. Patients who are bedridden for a long time face the problem of continuous compression of local limbs. If the limbs are under pressure for a long time and cause tissue hypoxia, bedsores will occur. Therefore, patients who are bedridden for a long time need to turn over and activate their bodies frequently. The common anti-bedsore mattresses currently have the function of assisting patients to turn over, but they still cannot alleviate the problem of blood circulation problems caused by long-term compression. Patients still face a greater risk of tissue necrosis.

[0003] In the prior art, patent number: CN213607674U discloses an anti-bedsore air mattress with a turning over function, including a base, the top of the base is connected to a mattress frame, one end of the interior of the mattress frame is installed with a third air cushion, and the other end of the interior of the mattress frame is connected with a first air cushion and a second air cushion, the second air cushion is located at a position on one side of the first air cushion, a controller is installed on one side of the mattress frame, and an air pump is fixed inside the mattress frame near the bottom of the first air cushion. The utility model can manually inflate and deflate the first air cushion and the second air cushion in turn through the cooperation of the first air cushion, the second air cushion, and the solenoid valve and other structures, so as to facilitate the patient to turn over to the left or right, and at the same time, the cyclic operation of turning over on the left side, lying flat, turning over on the right side, and lying flat can be realized through the function time setting.

[0004] Although the above-mentioned anti-bedsore air mattress can achieve the purpose of helping the patient to turn over by setting up an air pump and multiple air cushions, in actual application, there are still the following shortcomings: when turning over the patient on the turning air mattress, the patient needs to move to a suitable position, and the patient is generally located in the middle of the bed, resulting in poor turning effect.

[0023] Embodiment 1

[0024] like Figure 1-4 As shown, the utility model proposes an anti-bedsore mattress with a turning over function, comprising a mattress body 1, a notch is provided on the top wall of the mattress body 1, and two mountain-shaped turning over pads 2 are symmetrically and rotatably installed in the notch, and two rectangular openings are formed between the two mountain-shaped turning over pads 2, and two limiting columns 9 are fixedly installed on the left and right inner walls of the mattress body 1, and two annular pads 3 are slidingly sleeved on the peripheries of the two limiting columns 9, and the top wall of each annular pad 3 passes through a rectangular opening, and racks 4 are fixedly installed on the upper and lower inner walls of the annular pad 3, and a servo motor 5 and a bearing block 6 are fixedly installed on the left and right inner walls of the mattress body 1 respectively, and a rotating rod 7 is fixedly connected to the output end of the servo motor 5, and the end of the rotating rod 7 away from the servo motor 5 is rotatably connected to the bearing block 6, and two gears 8 are fixedly sleeved on the periphery of the rotating rod 7, and the gears 8 are simultaneously engaged with the corresponding two racks 4, and a lifting mechanism is fixedly installed on the bottom inner wall of the mattress body 1 for driving the two mountain-shaped turning over pads 2 to tilt.

[0025] In this embodiment: the lifting mechanism includes two hydraulic pumps 12 fixedly mounted on the inner wall of the bottom of the mattress body 1, and the output ends of the hydraulic pumps 12 are fixedly connected to fixed blocks. Through this arrangement, starting the hydraulic pump 12 can drive the fixed blocks fixedly connected to the output ends to be lifted and lowered; the bottom of the mountain-shaped turning pad 2 is fixedly mounted with a slide rail 13, and the bottom side of the slide rail 13 is slidably mounted with an articulated block 14, and the articulated block 14 is hinged to the corresponding fixed block. Through this arrangement, when the fixed block is lifted or lowered, the articulated block 14 will be driven to rotate and lift, and at the same time, the articulated block 14 will slide in the slide rail 13, and support the mountain-shaped turning pad 2 to drive one side thereof to lift and lower, so that the mountain-shaped turning pad 2 can be tilted; the tops of the annular pad 3 and the mountain-shaped turning pad 2 are flush with the top of the mattress body 1. Through this arrangement, it is avoided that the uneven height affects the comfort.

[0026] Embodiment 2

[0027] like Figure 1-4 As shown, the utility model proposes an anti-bedsore mattress with a turning over function. Compared with the first embodiment, a support column 10 is fixedly installed on the bottom inner wall of the mattress body 1, and rotation holes are opened on both sides of the support column 10. Through this arrangement, other components can rotate with it through the rotation holes on the support column 10; a rotating shaft 11 is fixedly installed on the bottom of the mountain-shaped turning over pad 2, and the rotating shaft 11 is rotatably connected to the support column 10. Through this arrangement, the bottom of the support column 10 is supported by the support column 10, and the mountain-shaped turning over pad 2 can also rotate thereon; a through hole is opened on the support column 10, and the rotating rod 7 passes through the through hole. Through this arrangement, the position of the support column 10 is prevented from hindering the rotation of the rotating rod 7.

[0028] Working principle: When using this device, first start the servo motor 5 according to the patient's position. The servo motor 5 drives the rotating rod 7 to rotate on the bearing block 6. The rotating rod 7 drives the two gears 8 fixedly mounted on the periphery thereof to rotate. The gears 8 drive the two racks 4 meshing therewith to move in the opposite direction, thereby driving the annular pad 3 fixedly connected to the rack 4 to rotate on the two limit columns 9. The tops of the two annular pads 3 are horizontally displaced left and right, thereby helping the patient to move left and right to a position suitable for turning over. Start the hydraulic pump 12 to drive the fixed block fixedly connected to its output end to rise. When the fixed block rises, it will drive the hinge block 14 to rotate and rise. At the same time, the hinge block 14 will slide in the slide rail 13, and support the mountain-shaped turning pad 2 to drive one side thereof to rise, so that the mountain-shaped turning pad 2 can be tilted, and the tilting of the mountain-shaped turning pad 2 can help the patient to turn over.

[0029] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
