DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In order to provide sufficient cushioning and support for patients, existing turning pads usually adopt a closed structure design and are relatively thick, which easily restricts air circulation, resulting in poor air permeability of the turning pad. The sweat and heat of the patient in contact with the turning pad are difficult to evaporate, increasing the risk of pressure sores. Especially in hot weather, it is easy for patients to feel stuffy and uncomfortable, affecting their recovery.

[0024] To solve the defects of the above turning mat during use, please refer to Figure 1-Figure 4The utility model provides a turning pad for preventing pressure sores, which can automatically ventilate the lower air holes when the patient adjusts his posture and turns over. The upper air holes and ventilation slots can accelerate the circulation of air in the equipment, optimize the air permeability of the equipment, and avoid the accumulation of sweat and heat at the contact part between the patient and the equipment, thereby reducing the risk of pressure sores and enhancing the comfort of patients. The device is based on a support pad 1, and a stress pad 2 is hinged on one side of the top of the support pad 1. In order to improve the air permeability of the stress pad 2 while ensuring the supporting effect of the stress pad 2 on the patient, an adjustment mechanism 3 is provided between the support pad 1 and the stress pad 2. The adjustment mechanism 3 can provide sufficient supporting force for the stress pad 2 on the one hand, and can adjust the slope of the stress pad 2 on the other hand. The stress pad 2 is set to be adjustable, which can meet the posture adjustment needs of different patients, facilitate the patient to adjust to different postures, and improve the practicality of the device. A plurality of rows of lower air holes 6 are provided on the stress pad 2, and an air permeable pad 4 is provided on the top of the stress pad 2. A ventilation mechanism 5 for squeezing and discharging the gas in the lower air permeable holes 6 is provided on the back of the air permeable pad 4. A plurality of ventilation slots 7 are also provided, and ventilation holes 61 are provided on the inner wall of the lower air hole 6. The lower air hole 6 is connected with the ventilation slots 7 through the ventilation holes 61. When the patient leans on the breathable pad 4, the gas in the lower air hole 6 can be squeezed by the ventilation mechanism 5, and the gas in the lower air hole 6 can be squeezed and discharged from the ventilation holes 61 to the ventilation slots 7. The multiple columns of lower air holes 6 are evenly distributed at equal intervals, and the multiple ventilation slots 7 correspond to the multiple columns of lower air holes 6 respectively, and the ventilation slots 7 are arranged in strips. The squeezed and discharged gas can be discharged to the outside of the stress pad 2 along the ventilation slots 7, and new air can be injected into the lower air hole 6 in the process of the patient adjusting the posture to realize ventilation of the lower air hole 6, thereby promoting the circulation of air inside the equipment and optimizing the air permeability of the equipment.

[0025] In order to enable the equipment to achieve automatic ventilation as the patient turns over, a plurality of rows of squeezing rods 51 are specially provided, and the plurality of rows of squeezing rods 51 correspond to the plurality of rows of lower air holes 6 respectively. One end of the squeezing rod 51 is fixedly installed on the back of the air pad 4, and the other end of the squeezing rod 51 extends to the lower air hole 6 and a piston 52 is fixedly installed therein. The diameter of the piston 52 is adapted to the lower air hole 6, and the piston 52 can be pushed and pulled by the squeezing rod 51. During the pushing and pulling process, the piston 52 can realize the extraction and release of gas in the lower air hole 6. When the patient leans on the air pad 4, the air pad 4 squeezes the squeezing rod 51 to slide toward the inside of the lower air hole 6, and the squeezing rod 51 drives the piston 52 to press downward. The piston 52 presses downward to squeeze the gas in the lower air hole 6, so that the gas in the lower air hole 6 is discharged into the ventilation groove 7 through the ventilation hole 61.

[0026] After the patient squeezes the squeezing rod 51 and the piston 52 into the lower air vent 6, as the patient adjusts his posture, the piston 52 cannot automatically draw fresh air into the lower air vent 6. In order to solve this technical problem, a connecting spring 53 is sleeved on the outer surface of the squeezing rod 51. The upper end of the connecting spring 53 is fixedly connected to the back of the air pad 4, and the lower end of the ventilation mechanism 5 is fixedly connected to the top of the stress pad 2. When the squeezing rod 51 is squeezed into the lower air vent 6, the connecting spring 53 will also be deformed as it is squeezed. After the connecting spring 53 is deformed, it has elastic force. When the patient adjusts his posture or turns over, the pressure of the patient on the air pad 4 disappears, and the connecting spring 53 can push the air pad 4 upward through its own elastic force. The air pad 4 drives the piston 52 to slide upward through the squeezing rod 51. The upward sliding of the piston 52 can draw fresh air from the outside into the lower air hole 6, thereby realizing the ventilation operation of the lower air hole 6.

[0027] Due to the gap between the stress pad 2 and the breathable pad 4, dust and impurities can easily enter the lower air holes 6 and the ventilation slots 7 from the gap between the two, which can easily cause dust to accumulate in the air pad 4, affecting the hygiene of the equipment. In addition, the gap between the stress pad 2 and the breathable pad 4 is small, which makes it more troublesome to clean. In order to solve this technical problem, side sealing plates 11 are fixedly connected to both sides of the stress pad 2. A plurality of side air holes 8 are opened on the side sealing plates 11. The plurality of side air holes 8 are respectively connected to a plurality of ventilation slots 7. The two sides of the stress pad 2 and the breathable pad 4 are blocked by the side sealing plates 11. The setting of the side air holes 8 can prevent the side sealing plates 11 from affecting the ventilation effect of the ventilation slots 7, and a filter is provided in the side air holes 8 to intercept a large amount of dust and impurities.

[0028] In order to further optimize the ventilation effect of the equipment, a plurality of rows of upper ventilation holes 9 are opened on the upper surface of the stress pad 2, and the plurality of rows of upper ventilation holes 9 correspond to the plurality of rows of lower ventilation holes 6 respectively, and the upper ventilation holes 9 are arranged in a ring shape, and the axis of the upper ventilation holes 9 is solidly arranged for fixing the extrusion rod 51. The upper ventilation holes 9 cooperate with the lower ventilation holes 6 to make the equipment have a double-layer ventilation design, which can further promote the circulation of air.

[0029] In order to provide sufficient support for the stress pad 2, refer to Figure 2 As shown, the support seat 31 is fixedly installed on the back of the stress pad 2, and a support rod 32 is rotatably installed inside the support seat 31. A limiting plate 33 is fixedly connected to the center position of the top of the support pad 1. A plurality of limiting grooves 34 for the support rod 32 to be inserted are provided on the limiting plate 33. By inserting the support rod 32 into different limiting grooves 34, the inclination angle of the support rod 32 can be controlled, and then the slope of the breathable pad 4 can be controlled. By limiting the support rod 32 by the limiting plate 33, the support rod 32 can provide sufficient supporting force for the breathable pad 4, thereby providing a stable supporting effect for the patient.

[0030] Since the lower end of the breathable pad 4 is hinged to the support pad 1, in order to ensure that the breathable pad 4 can rotate smoothly, the lower end of the breathable pad 4 cannot be flush with the hospital bed, resulting in a gap between the breathable pad 4 and the hospital bed, affecting the user experience. In order to solve this technical problem, a transition pad 10 is installed at the lower end of the breathable pad 4. The transition pad 10 is provided with anti-slip grooves. The material of the transition pad 10 is a deformable material such as high-density sponge, memory foam or latex, so that the transition pad 10 can adaptively deform with the rotation of the breathable pad 4. The breathable pad 4 can be transitioned to the hospital bed through the transition pad 10 to avoid a fault between the breathable pad 4 and the hospital bed, thereby enhancing the comfort of equipment use, and the setting of the anti-slip grooves can also enhance the anti-slip property of the equipment.
