AI Technical Summary
Existing pressure ulcer prevention positioning supports cannot be adjusted in height individually, nor can they adapt to changes in patient position, resulting in low comfort and easy damage.
The system employs the coordinated operation of a lifting drive belt and a guide traction belt. The lifting drive belt precisely controls the height and angle of the support block, while the guide traction belt ensures that the support block moves within a safe range. A synchronous gear structure is used to ensure traction synchronization, thus achieving adaptive support.
It enables precise height and angle adjustment of the support blocks, enhancing the stability and lifespan of the device, improving patient comfort and safety, and reducing the risk of pressure ulcers.

Technical Field
[0001] This utility model relates to the field of pressure ulcer prevention technology, specifically to a pressure ulcer prevention body support frame. Background Technology
[0002] Pressure ulcers, also known as pressure sores, are caused by prolonged pressure on local tissues, leading to persistent ischemia, hypoxia, and malnutrition, ultimately resulting in tissue necrosis and ulceration. When a part of the body is subjected to significant pressure for an extended period, capillary blood flow in that area is obstructed. This not only causes immense pain for the patient but also greatly increases the workload for caregivers. Anti-pressure ulcer positioning supports, as an important medical device, primarily function to reduce pressure on specific parts of the body, thereby effectively assisting patients in maintaining a proper posture, preventing the occurrence of pressure ulcers. They can reduce frequent discomfort caused by improper positioning, effectively prevent pressure ulcers, alleviate patient suffering, and keep the body in a relatively comfortable state. Furthermore, they help promote gastrointestinal motility, as patients can maintain a proper posture with the support of the support, facilitating the normal transport of food through the gastrointestinal tract.

[0027] Lifting drive belt 12 can be pulled during lifting to prevent lifting drive belt 12 from detaching from support lifting groove 31.
[0028] As shown in the drawings, Figures 3-4 The utility model provides a kind of anti-pressure sore body position support frame technical scheme: preferably, lifting drive belt 12 includes two drive columns 123, two drive columns 123 are set to inside left and right sides of support lifting groove 31 in parallel left and right, two drive columns 123 outer surfaces are commonly provided with lifting belt 122, lifting belt 122 outer surface is provided with several upper and lower penetrating fixing holes 124, drive column 123 front and rear ends are fixedly connected with lifting drive gear 121, rear lifting drive gear 121 rear end is provided with drive motor, the rotating directions of two drive motors are opposite, and front lifting drive gear 121 front end is rotatably connected to the inside of support lifting groove 31.
[0029] When the height of the support block 11 needs to be adjusted, the drive motor starts and drives the lifting drive gear 121 connected to it to rotate, thereby driving synchronous rotation. Because the two drive motors are installed in opposite directions, the reverse rotation of the two drive columns 123 will simultaneously wind the lifting belt 122, so that the lifting belt 122 lifts the middle part by winding, thereby raising and lowering the support block 11.
[0030] like Figures 3-4 As shown, this utility model provides a technical solution for a pressure ulcer prevention body positioning support frame: preferably, the support block 11 includes a support main block 111, the support main block 111 is disposed on the outer surface of the lifting belt 122, a movable fixing column 112 is fixedly connected inside the support main block 111, the movable fixing column 112 can pass through the fixing hole 124, a plurality of support main blocks 111 are respectively connected to the outer surface of the lifting belt 122 through the fixing hole 124, and a plurality of support main blocks 111 are connected in series on the outer surface of the lifting belt 122.
