Furthermore, the adjustment process is smooth and gentle, reducing discomfort caused by local pressure and improving patient safety and comfort.

Description

Technical Field

[0001] This utility model relates to the field of body positioning assistance technology, and in particular to a body positioning assistance device. Background Technology

[0002] Thoracic Surgery I is a specific department within thoracic surgery, categorized based on factors such as disciplinary development and disease classification. The specific services and specialties of Thoracic Surgery I vary between hospitals. Generally, Thoracic Surgery I primarily diagnoses and treats diseases of the lungs, esophagus, mediastinum, and chest wall, such as lung cancer, esophageal cancer, mediastinal tumors, pectus excavatum, and pectus carinatum. It also handles the treatment of chest injuries. Its medical team typically consists of chief physicians and associate chief physicians, possessing extensive clinical experience and professional skills. They are capable of performing various advanced treatments, including thoracoscopic minimally invasive surgery and robotic surgery, to improve patient outcomes and quality of life.

[0003] A postural assistive device disclosed in publication number CN116807817U, although the present invention relates to a postural assistive device, achieves the effect of assisting patients in performing a knee-hugging movement and fixing their body position. The present invention includes a safety baffle with a first clearance groove in the middle. A lower limb fixation component and an upper limb fixation component are slidably disposed in the first clearance groove. First toothed grooves are symmetrically formed on both sides of the lower part of the first clearance groove. A plurality of fixation components are fixedly disposed on both sides of the safety baffle. The lower limb fixation component includes a foot fixation structure, a popliteal fossa limiting structure, and a lower leg limiting structure. The foot fixation structure secures the patient's foot, while the popliteal fossa and lower leg limiting structures adjust and fix the angle between the patient's thigh and lower leg, preventing unpredictable changes in the patient's position during surgery and facilitating knee flexion. The upper limb fixation component includes a height adjustment structure and a hand fixation structure. Initially, the patient places their hand in the hand fixation structure for fixation. Subsequently, based on the patient's tolerance, a drive motor moves the upper and lower limb fixation components towards each other. Simultaneously, the height adjustment structure lowers the hand fixation structure, allowing the patient to assume a knee-hugging, back-flexed position for fixation. This achieves the effect of assisting the patient in performing the knee-hugging movement and stabilizing their position.

[0004] However, this positioning aid has the following drawbacks:

[0005] (1) When patients use body positioning assistive devices for treatment, the device angle may not be able to ensure that the patient is always in the best exposure position for the treatment operation, which will prolong the operation time of the staff and increase the risk of error.

[0006] (2) When patients use the postural assist device for treatment, the device may not be able to protect the patient's body, which may cause the patient to slip off the bed board, resulting in fractures or soft tissue contusions. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] The technical problem solved by this utility model is to provide a highly practical, simple-to-operate, and structurally simple positioning assistive device. This addresses the issues raised in the background art, such as the difficulty in ensuring the patient is always in the optimal exposure position during treatment using the positioning assistive device, leading to prolonged operation time for staff and increased risk of errors, and the possibility that the device may not adequately protect the patient's body, causing the patient to slip off the bed and suffer fractures, soft tissue contusions, etc.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model is implemented through the following technical solution: a body positioning assist device, comprising: a support component, a body positioning adjustment component, and a protective component, wherein the support component is composed of a support leg A and a support leg B, one end of the support leg A is fixedly connected to a connecting rod, and one end of the connecting rod is fixedly connected to the support leg B;

[0011] The body position adjustment assembly consists of a fixed rod and a buffer pad disposed between the connecting rods. A rotating block A is rotatably connected to the surface of the fixed rod. A hydraulic telescopic rod is fixedly connected to one end of the rotating block A. A rotating block B is fixedly connected to one end of the hydraulic telescopic rod. A limiting groove block A is rotatably connected to the surface of the rotating block B. A reclining plate A is fixedly connected to the top of the limiting groove block A. A buffer pad is fixedly connected to the top of the supporting leg A. The top of the buffer pad is movably connected to the reclining plate A.

[0012] The protective assembly consists of C-limiting groove blocks and nuts disposed on both sides of the A-side and B-side lying plates. A rotating rod is rotatably connected to the inner wall of the C-limiting groove block, and a C-rotating block is rotatably connected to the surface of the rotating rod. A guardrail is fixedly connected to the top of the C-rotating block, and threaded rods are fixedly connected to both ends of the rotating rod. Nuts are threadedly connected to the surface of the threaded rods.

[0013] Optionally, both ends of the surface of the A-type lying plate are fixedly connected to B-type limiting groove blocks, and the inner wall of the B-type limiting groove block is rotatably connected to a D-type rotating block. The surfaces of the B-type limiting groove block and the D-type rotating block are both provided with A-type circular holes, and the inner wall of the A-type circular holes is rotatably connected to an A-type limiting rod. One end of the D-type rotating block is fixedly connected to the B-type lying plate, and the A-type limiting rod serves to rotate the B-type limiting groove block and the D-type rotating block.

[0014] Optionally, the surface of the A rotating block is provided with a B circular hole, the inner wall of the B circular hole is rotatably connected to a fixed rod, and both ends of the surface of the fixed rod are fixedly connected with limit tubes, which serve to limit the A rotating block.

[0015] Optionally, both the B rotating block and the A limiting groove block have C circular holes on their surfaces. The inner wall of the C circular hole is rotatably connected to the B limiting rod, which serves to rotate the B rotating block and the A limiting groove block.

[0016] Optionally, both the C-limiting groove block and the C-rotating block have D-shaped holes on their surfaces. The inner wall of the D-shaped hole is rotatably connected to a rotating rod, which in turn rotates the C-limiting groove block and the C-rotating block.

[0017] Optionally, the bottom of both support leg A and support leg B are fixedly connected with four casters, which are used to move the device.

[0018] (III) Beneficial Effects

[0019] This utility model provides a body positioning assistive device, which has the following beneficial effects:

[0020] 1. This positioning assistance device, through the setting of the positioning adjustment component, allows the patient to first lie on top of the A-bed and B-bed, with their upper body against the A-bed. The operator first activates the hydraulic telescopic rod. When the hydraulic telescopic rod extends, it exerts an outward pushing force on the A-rotating block, forcing the A-rotating block to rotate around the fixed rod in a direction away from the support component. The A-limiting groove block then drives the A-bed to rotate. Simultaneously, the other end of the hydraulic telescopic rod exerts a pulling force on the B-rotating block, causing the B-rotating block to pull the A-limiting groove block. The A-bed gradually tilts upward as the A-limiting groove block is pulled until the A-bed tilts to the target positioning angle for treating the patient's chest cavity. This achieves the effect of smoothly tilting the A-bed, with the patient's upper body against it, to the target positioning angle for treating the chest cavity, precisely adapting to the positioning requirements of chest cavity treatment. This avoids angle deviation and ensures that the patient's chest cavity is always in the optimal exposure position for treatment, reducing the reduction of treatment effectiveness or operational risks caused by positioning errors. Furthermore, the adjustment process is smooth and gentle, reducing discomfort caused by local pressure and improving patient safety and comfort.

[0021] 2. This positioning assist device, through the setting of protective components, allows the staff to first rotate the nuts at both ends of the rotating rod when the guardrail needs to be deployed for protection. This moves the rod along the threaded rod away from the C-limiting groove until the nuts separate from the side of the C-limiting groove. Then, the guardrail is manually pushed, and the C-limiting block rotates synchronously around the rotating rod. The rotating rod rotates synchronously within the D-circular hole of the C-limiting groove until the guardrail rotates to a protective angle perpendicular to the reclining board. Then, the nuts at both ends of the rotating rod are rotated in the opposite direction, moving the rod along the threaded rod towards the C-limiting groove until the nuts are firmly pressed against the side of the C-limiting groove. This achieves the effect of providing effective protection for patients lying on the A and B reclining boards. Thus, the guardrail can be quickly deployed when protection is needed and easily retracted when the patient needs to get on or off the reclining board, preventing the guardrail from becoming an obstacle. This balances the diverse needs of protective function and usage scenarios, ensuring structural stability and reliability. The guardrail will not shift due to the patient leaning against it, slight collisions, or slight shaking of the device, completely eliminating the risk of guardrail loosening and causing protective failure.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] Please see Figures 1 to 5 This utility model provides a technical solution: a body position assist device, including: a support component 1, a body position adjustment component 2 and a protective component 3. The support component 1 is composed of an A support leg 101 and a B support leg 103. One end of the A support leg 101 is fixedly connected to a connecting rod 102, and one end of the connecting rod 102 is fixedly connected to the B support leg 103.

[0033] The body position adjustment component 2 consists of a fixed rod 201 and a buffer pad 207 disposed between connecting rods 102. A rotating block 202 is rotatably connected to the surface of the fixed rod 201. One end of the rotating block 202 is fixedly connected to a hydraulic telescopic rod 203. The rated load of the hydraulic telescopic rod 203 is ≥80kg, the effective stroke is 300-500mm, the angle adjustment range is 0-60°, the control accuracy is ±1°, and the telescopic speed is 0.5-1mm / s. One end of the hydraulic telescopic rod 203 is fixedly connected to a rotating block 204, and the rotating block 204... The surface of component 4 is rotatably connected to a limiting groove 205 (A). A reclining board 206 is fixedly connected to the top of the limiting groove 205. A cushioning pad 207 is fixedly connected to the top of the support leg 101. The cushioning pad 207 is made of medical-grade memory foam, with a thickness of 50mm ± 2mm, an elastic modulus of 50kPa ± 5kPa, and antibacterial properties conforming to GB / T20944.3. The top of the cushioning pad 207 is movably connected to the reclining board 206. Through the setting of the position adjustment component 2, the patient first lies down between the reclining board 206 and the reclining board 105. With the upper body resting against the A-side reclining board 206, the worker first activates the hydraulic telescopic rod 203. When the hydraulic telescopic rod 203 extends, it exerts an outward pushing force on the A-rotating block 202, forcing the A-rotating block 202 to rotate around the fixed rod 201 in a direction away from the support component 1. The A-limiting groove block 205 will then drive the A-side reclining board 206 to rotate. At the same time, the other end of the hydraulic telescopic rod 203 will exert a pulling force on the B-rotating block 204, causing the B-rotating block 204 to pull the A-limiting groove block 205. The A-side reclining board 206 moves with the A-limiting groove block 205. The movement gradually tilts upwards until the A-sit board 206 tilts to the target body position angle for treating the patient's chest cavity. This achieves the effect of the A-sit board 206, which allows the patient's upper body to fit smoothly, tilting to the target body position angle for treating the chest cavity. This precisely matches the body position requirements for chest cavity treatment, thereby avoiding angle deviation and ensuring that the patient's chest cavity is always in the optimal exposure position for treatment. This reduces the reduction of treatment effectiveness or operational risks caused by body position errors. Furthermore, the adjustment process is smooth and gentle, reducing discomfort caused by local pressure and improving patient safety and comfort.

[0034] The protective component 3 consists of a C-limiting groove block 301 and nuts 306 located on both sides of the A-side plate 206 and the B-side plate 105. A rotating rod 302 is rotatably connected to the inner wall of the C-limiting groove block 301. A C-rotating block 303 is rotatably connected to the surface of the rotating rod 302. A guardrail 304 is fixedly connected to the top of the C-rotating block 303. The guardrail 304 is made of stainless steel, with a height of 700mm ± 5mm, a lateral load capacity of ≥80kg, and a locking torque of 25N·m. Threaded rods 305 are fixedly connected to both ends of the rotating rod 302, and nuts 306 are threaded onto the surface of the threaded rods 305. When the guardrail 304 needs to be deployed for protection, the operator first rotates the nuts 306 at both ends of the rotating rod 302, causing it to move away from the C-limiting groove block 301 along the threaded rod 305 until the nuts 306 separate from the side of the C-limiting groove block 301. Then, the guardrail 304 is manually pushed, and the C-limiting groove block 304 is deployed. Block 303 rotates synchronously around the rotating rod 302 along with the guardrail 304. The rotating rod 302 rotates synchronously within the D-hole of the C-limiting groove block 301 until the guardrail 304 rotates to a protective angle perpendicular to the reclining board. Then, the nuts 306 at both ends of the rotating rod 302 are rotated in the opposite direction, causing them to move along the threaded rod 305 towards the C-limiting groove block 301 until the nuts 306 press tightly against the side of the C-limiting groove block 301. This achieves the effect of providing effective protection for patients lying on the A reclining board 206 and the B reclining board 105. Thus, the guardrail 304 can be quickly deployed when protection is needed, and it can also be easily retracted when the patient needs to get on or off the reclining board, preventing the guardrail 304 from becoming an obstacle. This balances the diverse needs of protective functions and usage scenarios, thereby ensuring that the locking structure is stable and reliable and will not shift due to the patient leaning against it, slight collisions, or slight shaking of the device, completely eliminating the risk of the guardrail 304 loosening and causing the protection to fail.

[0035] Both ends of the surface of the A-type lying plate 206 are fixedly connected to the B-type limiting groove block 104. The inner wall of the B-type limiting groove block 104 is rotatably connected to the D-type rotating block. The surfaces of the B-type limiting groove block 104 and the D-type rotating block are both provided with A-type circular holes. The inner wall of the A-type circular hole is rotatably connected to the A-type limiting rod. One end of the D-type rotating block is fixedly connected to the B-type lying plate 105. The A-type limiting rod is used to rotate the B-type limiting groove block 104 and the D-type rotating block.

[0036] A circular hole B is provided on the surface of rotating block A 202. The inner wall of circular hole B is rotatably connected to fixed rod 201. Both ends of the surface of fixed rod 201 are fixedly connected to limit tubes. The limit tubes serve to limit the movement of rotating block A 202.

[0037] Both the B rotating block 204 and the A limiting groove block 205 have C circular holes on their surfaces. The inner wall of the C circular hole is rotatably connected to the B limiting rod. The B limiting rod is used to rotate the B rotating block 204 and the A limiting groove block 205.

[0038] Both the C-limiting groove block 301 and the C-rotating block 303 have D-shaped holes on their surfaces. The inner wall of the D-shaped hole is rotatably connected to the rotating rod 302. The rotating rod 302 is used to rotate the C-limiting groove block 301 and the C-rotating block 303.

[0039] Both support leg A 101 and support leg B 103 are fixedly connected to four casters at their bottoms. These casters enable the device to be moved.

[0040] In this invention, the working steps of the device are as follows:

[0041] First step: The patient first lies down on top of the A-bed 206 and B-bed 105, with the upper body against the A-bed 206. The staff first activates the hydraulic telescopic rod 203. When the hydraulic telescopic rod 203 extends, it will exert an outward force on the A-rotating block 202, forcing the A-rotating block 202 to rotate around the fixed rod 201 in a direction away from the support component 1. The A-limiting groove block 205 will drive the A-bed 206 to rotate. At the same time, the other end of the hydraulic telescopic rod 203 will exert a pulling force on the B-rotating block 204, causing the B-rotating block 204 to pull the A-limiting groove block 205. The A-bed 206 gradually tilts upward as the A-limiting groove block 205 is pulled, until the A-bed 206 tilts to the target body position angle for treating the patient's chest cavity.

[0042] The second step: When the guardrail 304 needs to be deployed for protection, the staff first rotates the nuts 306 at both ends of the rotating rod 302, so that it moves away from the C-limiting groove block 301 along the threaded rod 305 until the nuts 306 separate from the side of the C-limiting groove block 301. The guardrail 304 is then manually pushed, and the C-rotating block 303 will rotate synchronously around the rotating rod 302 with the guardrail 304. The rotating rod 302 rotates synchronously in the D-circular hole of the C-limiting groove block 301 until the guardrail 304 rotates to a protection angle perpendicular to the lying board. Then, the nuts 306 at both ends of the rotating rod 302 are rotated in the opposite direction, so that they move closer to the C-limiting groove block 301 along the threaded rod 305 until the nuts 306 are pressed tightly against the side of the C-limiting groove block 301.
