Description

Technical Field

[0001] This invention relates to the field of medical assistive devices, and in particular to an adjustable body position support device for musculoskeletal ultrasound examination. Background Technology

[0002] Ultrasound examination is a non-invasive medical imaging technique that uses high-frequency sound waves to generate images of organs and tissues inside the body. Musculoskeletal ultrasound is a medical imaging technique used to evaluate soft tissue structures such as muscles, bones, joints, ligaments, and tendons. It is often used to examine knee joint injuries. During the examination, an auxiliary fixation device is used to bend the patient's leg to the required angle, so as to facilitate a comprehensive examination of the knee joint from all angles. In musculoskeletal ultrasound examination, the patient needs to maintain a specific position according to the examination site.

[0003] However, traditional ultrasound beds are mostly fixed structures, providing only basic support for lying flat. On the one hand, different patients have different heights and body types, and the examination sites have different requirements for body position. Fixed beds cannot be precisely adapted, forcing patients to actively exert force to maintain their posture, which can easily lead to muscle fatigue and body position deviation, affecting the clarity and stability of ultrasound image acquisition. On the other hand, traditional body position adjustment often relies on medical staff to manually drag and elevate the patient, which is cumbersome and inefficient, especially for emergency patients, critically ill patients, or examination scenarios that require maintaining a special posture for a long time, making it unsuitable. In addition, uneven support during manual adjustment may also cause joint compression and body slippage, reducing examination comfort and even causing patient resistance. Summary of the Invention

[0004] The main objective of this invention is to provide an adjustable body position support device for musculoskeletal ultrasound examination, which can effectively solve the problems of poor adaptability, low patient comfort, and low operation efficiency.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] An adjustable body positioning support device for musculoskeletal ultrasound examination includes a bed frame. The top of the bed frame has two sliding grooves (Section 1, Section 2, and Section 3). A sliding rod (Section 2) is fixedly installed within each sliding groove (Section 3). A backrest assembly is mounted on each sliding rod (Section 2) to support the patient's back at different angles. A screw (Section 1) is rotatably connected inside each sliding groove (Section 1). Each sliding rod (Section 1) is fixedly installed within each sliding groove (Section 2). An adjustment mechanism is mounted on each screw (Section 1). A support assembly (Section 1) is mounted on each sliding rod (Section 1). The support assembly (Section 1) includes a support rod (Section 1). A support assembly (Section 2) is mounted on the outer wall of each support rod (Section 1). The support assembly (Section 2) includes a screw (Section 2) and a support rod (Section 2). The adjustment mechanism can adjust the vertical height of the support rods (Section 1 and 2) and allows the support rod (Section 2) to rotate about the support rod (Section 1). The relative position of the support rods (Section 2 and 1) can be adjusted when the screw (Section 2) rotates.

[0007] Preferably, cotton sleeves are fixedly fitted onto the outer walls of both the first support rod and the second support rod.

[0008] Preferably, the backrest assembly includes a slider, a backrest cushion, and two fixed seats. The slider is slidably sleeved on the second slide rod and limited by the third slide groove. An electric push rod is fixedly installed on the top of the slider, and an mounting block is fixedly installed on the bottom of the backrest cushion. The output end of the electric push rod is hinged to the mounting block. Both fixed seats are fixedly installed on the top of the bed frame, and the backrest cushion is rotatably connected to the two fixed seats.

[0009] Preferably, the first support assembly further includes a second mounting base, which is slidably sleeved on the first sliding rod. A telescopic rod is fixedly installed on the top of the second mounting base, and a rotating arc plate is fixedly installed at the telescopic end of the telescopic rod. The first support rod is rotatably connected to the rotating arc plate.

[0010] Preferably, the second support assembly further includes a guide rod, the second screw is rotatably connected to the first support rod, the guide rod is fixedly connected to the first support rod, the second support rod is threaded onto the second screw and slidably mounted on the guide rod.

[0011] Preferably, a rotating handle is fixedly installed at one end of the screw.

[0012] Preferably, the adjustment mechanism includes a second motor, the output end of which is fixedly mounted with a rotating shaft, and both the rotating shaft and the first support rod are fixedly fitted with synchronous pulleys, and synchronous belts are fitted on the two synchronous pulleys.

[0013] Preferably, the adjustment mechanism further includes a mounting base, which is threaded onto the screw and slidably engaged with the slide groove. An electric push rod and a protective frame are fixedly mounted on the top of the mounting base. A protective cover is fixedly mounted on the output end of the electric push rod, and the motor is fixedly mounted inside the electric push rod.

[0014] Preferably, the screw is rotatably connected to the bed frame, two protective cylinders and a motor are fixedly installed at one end of the bed frame, one end of the screw is fixedly connected to the output end of the motor, the motor is located inside the protective cylinder, and a controller is fixedly installed at one end of the bed frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By adjusting the angle of the backrest assembly, layering the height, spacing, and angle of the support assembly, and coordinating the horizontal displacement, vertical lifting, and rotation of the adjustment mechanism, it can adapt to the needs of different heights, body types, and examination sites. It can achieve conventional positions such as lying flat, semi-sitting, and leg bending, as well as simulate special examination postures, breaking through the limitations of the traditional single support mode of ultrasound beds and effectively improving the scope of application.

[0017] 2. The slider displacement compensation design of the backrest component prevents the patient's body from slipping down. The composite material of the cotton cover cushions the pressure and reduces friction interference. The close-fitting adjustment of the support component reduces muscle tension and joint pressure, allowing the patient to maintain a stable posture for a long time without actively maintaining the position. This not only improves the patient's comfort but also avoids positional deviation caused by muscle fatigue, improves the clarity and stability of ultrasound image acquisition, and indirectly shortens the examination time.

[0018] 3. A dynamic adjustment system is constructed through motor drive and mechanical linkage: The transmission combination of motor one and screw one can finely adjust the position of the support components in real time according to changes in the patient's position. Motor two achieves precise dynamic control of the leg angle through synchronous pulley belt drive. Combined with the adaptive lifting of the electric push rod, a closed-loop adjustment is formed to adapt to changes in the patient's position and the real-time adaptation of the equipment, avoiding the drawback of traditional devices requiring shutdown and readjustment. At the same time, the sealed protection of the protective cylinder and protective cover, combined with the overload protection function of the controller, can automatically shut down the equipment in case of abnormality, ensuring equipment safety and preventing patient injury due to mechanical failure. This achieves a synergistic innovation of dynamic adjustment and intelligent protection, improving the safety of equipment use. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0027] like Figure 1-3 As shown, an adjustable body position support device for musculoskeletal ultrasound examination includes a bed frame 1. The top of the bed frame 1 has two sliding grooves 101, two sliding grooves 102, and a sliding groove 103. A sliding rod 106 is fixedly installed in the sliding groove 103. A backrest assembly 4 is provided on the sliding rod 106. The backrest assembly 4 can support the patient's back at different angles. The backrest assembly 4 includes a slider 405, a backrest pad 402, and two fixed seats 404. The slider 405 is slidably sleeved on the sliding rod 106 and limited by the sliding groove 103. An electric push rod 401 is fixedly installed on the top of the slider 405. An installation block 403 is fixedly installed on the bottom of the backrest pad 402. The output end of the electric push rod 401 is hinged to the installation block 403. The two fixed seats 404 are fixedly installed on the top of the bed frame 1. The backrest pad 402 is rotatably connected to the two fixed seats 404.

[0028] In this embodiment, the backrest assembly 4 is dynamically adjusted through a dual collaborative mechanism of telescopic drive of electric push rod 401 and horizontal sliding of slider 405: after the controller 2 triggers electric push rod 401, its output end drives backrest pad 402 to rotate around fixed seat 404 through mounting block 403, thereby achieving multi-angle support, improving the patient's lying comfort, reducing the frequency of manual adjustment by medical staff, and avoiding patient position shift due to muscle fatigue, thus indirectly improving the stability of ultrasound image acquisition.

[0029] Example 2

[0030] like Figure 4As shown, based on Embodiment 1, a screw 104 is rotatably connected inside the slide groove 101, and a slide rod 105 is fixedly installed inside the slide groove 102. An adjustment mechanism 5 is provided on the screw 104, and a support assembly 6 is provided on the slide rod 105. The support assembly 6 includes a support rod 601, and a support assembly 7 is provided on the outer wall of the support rod 601. The support assembly 7 includes a screw 701 and a support rod 703. The adjustment mechanism 5 can adjust the vertical height of the support rod 601 and the support rod 703, and can make the support rod 703 rotate about the support rod 601. When the screw 701 rotates, it can adjust the relative position of the support rod 703 and the support rod 601. Cotton sleeves 8 are fixedly fitted on the outer walls of both 601 and support rod 703. Support assembly 6 also includes mounting base 602, which is slidably fitted on slide rod 105. Telescopic rod 603 is fixedly installed on the top of mounting base 602. Rotating arc plate 604 is fixedly installed on the telescopic end of telescopic rod 603. Support rod 601 is rotatably connected to rotating arc plate 604. Support assembly 7 also includes guide rod 702. Screw 701 is rotatably connected to support rod 601. Guide rod 702 is fixedly connected to support rod 601. Support rod 703 is threaded onto screw 701 and slidably fitted on guide rod 702. A handle 704 is fixedly installed on one end of screw 701.

[0031] In this embodiment, the layered adjustment and adaptation design of support component 1 6 and support component 2 7 addresses the pain points of large individual leg shape differences and insufficient support stability in musculoskeletal ultrasound leg examinations. On the one hand, the telescopic rod 603 of support component 1 6 can adjust the initial support height of support rod 1 601 according to the patient's leg circumference, while the rotating arc plate 604 allows the angle of support rod 1 601 to be finely adjusted along the arc trajectory, ensuring its fit with the patient's leg joint and avoiding joint compression caused by rigid support. On the other hand, when the rotating handle 704 drives the screw 2 701 to rotate, support rod 2 703 slides precisely along the guide rod 702, flexibly adjusting the distance between it and support rod 1 601 according to the length of the patient's lower leg. This avoids muscle tension caused by the lower leg being suspended and prevents excessive support from hindering the examination of the ankle area. In addition, the cotton sleeve 8 on the outer wall of support rod 1 601 and support rod 2 703 is made of a composite material of high-density degreased cotton and breathable knitted fabric, which not only buffers the support pressure but also reduces the interference of clothing friction when the ultrasound probe moves, indirectly improving the efficiency of the examination operation.

[0032] Example 3

[0033] like Figure 4-6As shown, based on Embodiment 2, the adjustment mechanism 5 includes a second motor 501. A rotating shaft 502 is fixedly installed at the output end of the second motor 501. Synchronous pulleys 503 are fixedly sleeved on both the rotating shaft 502 and the support rod 601. A synchronous belt 504 is sleeved on the two synchronous pulleys 503. The adjustment mechanism 5 also includes a mounting base 505. The mounting base 505 is threaded onto the screw 104 and slides with the slide groove 101. An electric push rod 506 and a protective frame 508 are fixedly installed on the top of the mounting base 505. A protective cover 507 is fixedly installed at the output end of the electric push rod 506. The second motor 501 is fixedly installed inside the electric push rod 506. The screw 104 is rotatably connected to the bed frame 1. Two protective cylinders 3 and the first motor 107 are fixedly installed at one end of the bed frame 1. One end of the screw 104 is fixedly connected to the output end of the first motor 107. The first motor 107 is located inside the protective cylinder 3. A controller 2 is fixedly installed at one end of the bed frame 1.

[0034] In this embodiment, the device achieves precision, safety, and scenario adaptability through a multi-power source collaborative modular protection design: when motor 107 drives screw 104 to rotate, mounting base 505 slides smoothly along slide groove 101, which can drive support component 6 and support component 7 to move horizontally synchronously, adapting to the leg support needs of patients of different heights and avoiding misalignment of examination sites due to patient position deviation; motor 2 501 drives support rod 601 to rotate around the arc of rotation through the transmission structure of synchronous pulley 503 and synchronous belt 504. The rotation of plate 604 allows for adjustment of the patient's leg bending angle from 0° to 90° with a stable transmission ratio, avoiding jamming or overshoot during angle adjustment. Meanwhile, the protective sleeve 3 provides enveloping protection for motor 107, and the protective cover 507 provides sealed protection for motor 2 501, effectively preventing coupling agent drips and dust accumulation from corroding motor components during the examination, thus extending the device's service life. The integrated operation design of controller 2 reduces the operational complexity for medical personnel, making it particularly suitable for emergency and critical care scenarios where rapid musculoskeletal ultrasound examinations are required.

[0035] Working principle:

[0036] The patient first lies on one side of the backrest cushion 402. Then, the electric push rod 401 is activated wirelessly via the controller 2 module. When the output end of the electric push rod 401 extends or retracts, it drives the backrest cushion 402 to rotate via the mounting block 403. At the same time, the electric push rod 401 moves horizontally via the mounting block 403 and the slide rail 103, allowing the patient to lie comfortably on the bed frame 1. Then, the patient places their leg joints on the cotton sleeve 8 on the surface of the support rod 601, so that the support rod 601 initially supports the patient's legs. Then, the lower leg is placed on the cotton sleeve 8 on the surface of the support rod 703, so that the patient's lower leg is supported and the patient's legs are relaxed. The patient does not need to actively bend their legs for a long time, reducing the difficulty of the examination. Then, the medical staff can use instruments to perform an ultrasound examination on the patient's leg muscles.

[0037] Medical staff can also start motor 107 via the wireless module of controller 2. The output of motor 107 drives screw 104 to rotate. When screw 104 rotates, it engages with mounting base 505, causing mounting base 505 to slide within slide groove 101. When mounting base 505 moves, it drives support component 6 and support component 7 to move synchronously, causing support rod 601 and support rod 703 to move horizontally. This allows support rod 601 and support rod 703 to rotate with the backrest cushion 402. The device is designed to fit the patient's leg length, effectively expanding its applicability. Simultaneously, manually rotating the handle 704 causes the screw 701 to rotate. This rotation of the screw 701 drives the support rod 703 to slide between the screw 701 and the guide rod 702. This allows the support rod 703 to move closer to or further away from the support rod 601, thus adjusting the distance between the support rod 601 and the support rod 703 according to the patient's lower leg length. This ensures the patient's feet are not obstructed by the device, further improving patient comfort.

[0038] Furthermore, medical personnel can also activate motor 2 501. The output of motor 2 501 drives the rotating shaft 502 to rotate. The rotating shaft 502 drives the support rod 1 601 to rotate through two synchronous pulleys 503 and a synchronous belt 504. When the support rod 1 601 rotates, it drives the support rod 2 703 to rotate, which in turn drives the patient's lower leg to rotate, thereby adjusting the bending state of the patient's leg. This facilitates various testing procedures. Moreover, after the electric push rod 2 506 is activated, it can vertically push the protective cover 507 to move, causing the support rod 1 601 and the support rod 2 703 to move vertically, pulling on the patient's leg joint. In conjunction with other adjustment structures, the equipment ensures that the patient's body remains in a comfortable state during the examination, improving its applicability.
