Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a downward-facing body positioning assistive device with limb movement function. Background Technology

[0002] In the field of intraocular surgery, postoperative care is crucial for patient recovery. Some patients require prolonged periods in a downward-facing position post-surgery, making postoperative positioning management a key factor in ensuring surgical success. Specifically, after vitrectomy combined with intraocular gas or silicone oil tamponade, the filling gas or silicone oil has low density, floats upwards, and has high tensile strength. Patients routinely need to maintain a downward-facing position to utilize the buoyancy of the filling material to press against the retinal tear, promoting retinal reattachment, balancing intraocular pressure, and reducing the risk of postoperative complications. To meet this clinical need, devices to assist patients in maintaining this position have emerged, such as common positioning tables and lying tables.

[0003] For example, Chinese patent CN220899004U discloses a multifunctional prone positioning table, including a main structure and an auxiliary structure. Adjustable components allow for height adjustment of the tabletop, support plate, and movable legs to accommodate the patient's height and the bed height. The auxiliary structure includes a positioning headrest and an IV stand for catheter insertion, improving patient comfort in sitting and lying positions. However, this prone positioning table only improves support through adjustable structures. When using this table, the patient still needs to remain in a static prone position, limiting limb movement. Prolonged static prone positioning can easily lead to muscle soreness, limb numbness, joint stiffness, pressure sores, and deep vein thrombosis, affecting the patient's motivation for rehabilitation and the recovery of physical function. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a downward-facing body positioning assistive device with limb movement function, in view of the above-mentioned defects of the prior art.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A downward-facing posture assistive device with limb movement function is constructed, including a support plate and a support frame disposed at the bottom of the support plate. The support plate is provided with a facial support for supporting the patient's face and maintaining a downward-facing posture. It also includes a lower limb movement component and an upper limb movement component. The lower limb movement component includes a swingable foot pedal mounted on the support frame for placing the patient's feet and assisting the patient's lower limb movement. The upper limb movement component includes an elastic element and a handle for the patient to pull. The handle is connected to the elastic element, and the elastic element can provide resistance to the handle to assist the upper limb movement.

[0007] As an improvement to the lower body positioning assistive device, the lower limb movement component includes a mounting frame disposed between the two support frames, the mounting frame being rotatably mounted with a rotating shaft, and two foot pedals respectively mounted at both ends of the rotating shaft.

[0008] As an improvement to the downward-facing body positioning assist device, the inner side of the support frame is rotatably provided with a rotating shaft, and there are two foot pedals, which are respectively installed on the rotating shafts on both sides, and the foot pedals are rotatably connected to the rotating shafts.

[0009] As an improvement to the lower body positioning assist device, the support plate has a cavity with an opening along its length that communicates with the outside. The handle is slidably connected to the opening, and the elastic element is located inside the cavity with its two ends connected to the inner wall of the cavity and the handle, respectively.

[0010] As an improvement to the aforementioned downward-facing positioning aid, the elastic element is an elastic band.

[0011] As an improvement to the downward-facing positioning aid, the facial support includes at least two vertically arranged support columns, the top of which extends laterally into a facial support platform with an arc-shaped groove.

[0012] As an improvement to the lower-positioning assistive device, the support plate is at least partially transparent to form an observation area for the patient to view the status of the lower limb motor components.

[0013] As an improvement to the downward-facing body positioning aid, each handle is provided with a grip ball at its outer end.

[0014] As an improvement to the lower body positioning assist device, at least two support frames are provided, located on both sides of the bottom of the support plate. Each support frame includes at least two support legs, and a connecting rod is provided between the two support legs. Each support leg has a sliding groove at its top, and the support plate has a guide shaft that is slidably connected to the sliding groove. A lifting adjustment assembly is provided between the support frame and the support plate.

[0015] As an improvement to the lower body positioning assist device, the lifting adjustment assembly includes a threaded cylinder disposed on the support plate, a screw installed inside the threaded cylinder, and a driver disposed between the two support legs. The driver is connected to the screw and is used to drive the screw to rotate and adjust the height position of the support plate.

[0016] The beneficial effects of this invention are as follows: This auxiliary device, by providing movable foot pedals and resistance handles, allows patients to perform limb movements while maintaining a downward-facing position, effectively alleviating physical discomfort caused by prolonged stillness. Moderate limb movement helps promote blood circulation and metabolism. The swinging movements of the lower limbs can improve blood flow in the lower limbs, while the movements of the upper limbs overcoming the resistance of the elastic elements can strengthen upper limb muscles. Overall, this helps the patient's physical function recover and, to a certain extent, promotes the recovery process after ophthalmic surgery. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] A downward-facing posture assistive device with limb movement function, such as Figure 1 As shown, the system includes a support plate 1 and a support frame 2 located at the bottom of the support plate 1. A facial support 3 is mounted on the support plate 1 to support the patient's face and maintain a downward-facing position. It also includes a lower limb movement component 4 and an upper limb movement component 5. The lower limb movement component 4 includes a swingable footrest 41 mounted on the support frame 2 for placing the patient's feet and assisting in lower limb movement. The upper limb movement component 5 includes an elastic element 51 and a handle 52 for the patient to pull. The handle 52 is connected to the elastic element 51, which provides resistance to the handle 52 to assist in upper limb movement. Specifically, the patient sits on the side closest to the facial support 3 via an external seat, lies prone on the support plate 1, and places their face on the facial support 3. The facial support 3 provides a support point for the patient's face, stably supporting it and allowing the patient to maintain a downward-facing position, meeting the specific post-operative positional requirements for promoting retinal reattachment after intraocular surgery. The patient places their feet on the swingable footrest 41 mounted on the support frame 2. This assistive device allows patients to swing their lower limbs using the foot pedal 41. This swinging motion simulates everyday lower limb movements, causing the lower limb muscles to contract and relax, thus assisting lower limb movement. Simultaneously, the patient grips and pulls the handle 52. Since the handle 52 is connected to the elastic element 51, which has elastic properties, the elastic element 51 deforms when the handle 52 is pulled. According to the principle of elasticity, this deformation applies resistance to the handle 52. As the patient overcomes this resistance, the upper limb muscles are exercised, further assisting upper limb movement. This assistive device, by providing a movable foot pedal 41 and a resistance-applied handle 52, allows patients to perform limb movements while maintaining a downward-facing position, effectively alleviating discomfort caused by prolonged stillness. Moderate limb movement helps promote blood circulation and metabolism. The swinging motion of the lower limbs improves blood flow, while the upper limb movement against the resistance of the elastic element 51 strengthens upper limb muscles, contributing to the overall recovery of the patient's physical function and, to some extent, promoting the recovery process after ophthalmic surgery.

[0028] In some embodiments of this application, the lower limb movement component 4 includes a mounting frame 43 disposed between two support frames 2. The mounting frame 43 is rotatably mounted with a rotating shaft 42, and two foot pedals 41 are respectively mounted at both ends of the rotating shaft 42. Specifically, when the patient uses the assistive device, they sit on the support plate 1 and place their feet on the two foot pedals 41 respectively. Since the mounting frame 43 is rotatably mounted on the rotating shaft 42 between the two support frames 2, and the foot pedals 41 are respectively fixed at both ends of the rotating shaft 42, when the patient performs lower limb movements, such as pedaling, their feet exert force on the foot pedals 41, causing the foot pedals 41 to rotate around the rotating shaft 42, thereby driving the entire mounting frame 43 to swing around the rotating shaft 42. Alternating pedaling with both feet can simulate the movement effect of stepping in place or pedaling a bicycle, prompting the lower limb muscles to contract and relax rhythmically, simulating daily lower limb activities, thereby achieving the purpose of assisting lower limb movement. This allows the patient to fully activate the lower limb joints and muscles through simple pedaling movements. For example, after intraocular surgery, when patients maintain a downward-facing position for an extended period, this component can help them perform moderate lower limb exercises, preventing muscle atrophy and poor blood circulation caused by prolonged inactivity, strengthening lower limb muscles, and maintaining normal lower limb motor function.

[0029] In some other embodiments, the mounting bracket 43 and the support frame 2 are detachably connected. When the foot pedal 41 is not in use, the connection between the mounting bracket 43 and the support frame 2 can be disconnected, and the foot pedal 41 can be removed from the support frame 2, so that the patient has enough legroom when using it without moving, avoiding the patient's legs from bumping or hitting it.

[0030] In some embodiments of this application, such as Figure 2 As shown, a pivot 42 is rotatably mounted on the inner side of the support frame 2. Two foot pedals 41 are mounted on the pivot 42 on each side, and the foot pedals 41 are rotatably connected to the pivot 42. Specifically, when using this assistive device, the patient sits on the side closest to the face support 3 and places both feet on the foot pedals 41 on either side. When the patient's leg muscles exert force, the leg movement causes the feet to exert a forward or backward force on the foot pedals 41. Because the foot pedals 41 are mounted on the rotatable pivot 42 on the inner side of the support frame 2, and the foot pedals 41 and pivot 42 are rotatable, when the feet exert force, the foot pedals 41 will swing back and forth around the pivot 42, achieving a movement similar to stepping in place, thereby driving the lower limbs to perform flexion and extension movements. Simultaneously, because of the rotatable connection between the foot pedals 41 and pivot 42, when the patient's ankle makes a rotational movement, the foot pedals 41 can rotate accordingly, allowing the patient to perform ankle movements.

[0031] By swinging the foot pedal 41 back and forth, the thigh and calf muscles of the lower limbs can be effectively exercised, promoting blood circulation in these areas and preventing muscle atrophy due to prolonged inactivity. Simultaneously, the rotatable connection between the foot pedal 41 and the pivot 42 allows the patient to move their ankle joints during use, enhancing ankle flexibility and preventing stiffness. For patients who need to maintain a downward-facing position for extended periods, the design that allows for lower limb and ankle movement overcomes the limitations of traditional assistive devices, increasing the patient's independent movement space during rehabilitation and alleviating the boredom and discomfort caused by prolonged stillness, making treatment more acceptable and cooperative.

[0032] In other embodiments, the pivot 42 and the support frame 2 are detachably connected. Specifically, the support frame 2 is detachably connected to a bearing seat, and the pivot 42 is rotatably connected to the support frame 2 through the bearing seat. When the foot pedal 41 is not in use, the bearing seat can be detached from the support frame 2, and the foot pedal 41 can be removed from the support frame 2, so that the patient has enough legroom when not exercising, avoiding the patient's legs from bumping or hitting.

[0033] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the support plate 1 has a cavity 12, and the cavity 12 has an opening 13 along its length that communicates with the outside. The handle 52 is slidably connected to the opening 13. The elastic element 51 is located inside the cavity 12, and its two ends are connected to the inner wall of the cavity 12 and the handle 52, respectively. Specifically, when the patient grasps the handle 52 and pulls it along the opening 13, the handle 52 slides in the opening 13. Since one end of the elastic element 51 is connected to the handle 52 and the other end is connected to the inner wall of the cavity 12, as the handle 52 slides, the elastic element 51 is stretched. The elastic element 51 generates an elastic force in the opposite direction of the stretching, that is, it applies resistance to the handle 52. The patient needs to overcome this resistance and continue to pull the handle 52. When the patient releases the handle 52, the elastic element 51 returns to its original shape under its own elastic force, driving the handle 52 back to the initial position. This cycle is repeated to achieve reciprocating exercise of the upper limb. As the patient continuously overcomes the resistance of the elastic element 51 to pull the handle 52, the upper limb muscles need to exert continuous force, similar to strength training. This effectively exercises the biceps, triceps, and other muscle groups in the upper limb, enhancing muscle strength and preventing upper limb muscle atrophy caused by maintaining a fixed posture for a long time. During the process of pulling the handle 52, the contraction and relaxation of the muscles in the upper limb promotes the regular contraction and expansion of blood vessels, accelerating blood circulation in the upper limb and preventing blood stasis, numbness, and other conditions caused by prolonged stillness, thus helping to relieve discomfort in the upper limb.

[0034] In some embodiments of this application, the elastic element 51 is an elastic band. Specifically, when the patient pulls the handle 52 connected to the elastic element 51, the elastic element 51 is stretched as the handle 52 moves. Based on the elastic properties of the elastic element 51, a spring force opposite to the stretching direction is generated, forming resistance acting on the handle 52. The patient needs to overcome this resistance to continue pulling the handle 52, thereby exercising the upper limb muscles. When the patient releases the handle 52, the elastic element 51 returns to its initial state due to its elasticity, pulling the handle 52 back to a position close to the support plate 1, allowing the patient to perform the next pulling operation. The elastic band can be made of natural rubber, synthetic rubber (such as nitrile rubber, neoprene rubber), or elastic fibers (such as spandex, Lycra). In other embodiments, the elastic element 51 can also be a spring.

[0035] In some embodiments of this application, the facial support 3 includes two vertically arranged support columns 31, with the top of each support column 31 extending laterally into an arc-shaped grooved facial support platform 32. Specifically, when the patient uses this face-down positioning assistive device, they place their face on the facial support platform 32. The vertically arranged support columns 31 provide stable vertical support for the facial support platform 32, ensuring that the facial support platform 32 can firmly support the patient's face. The arc-shaped grooved facial support platform 32 conforms to the facial contours, distributing facial pressure and ensuring even force distribution across the face. Because its shape adapts to the face, it effectively reduces localized pressure on the face, allowing the patient to maintain a comfortable face-down position without affecting blood circulation due to excessive localized pressure.

[0036] The two support columns 31 work together to ensure the overall stability of the facial support 3, which can reliably support the patient's face and prevent the head from easily shaking when the patient is in a face-down position. This meets the requirements for postoperative stability after intraocular surgery and helps to promote retinal reattachment.

[0037] In some embodiments of this application, the facial support platform 32 employs a flexible pressure-reducing design. Its surface is covered with a 2-5cm thick medical-grade silicone or memory foam pad. The surface of the pad is ergonomically designed with a concave arc shape in the center. This arc shape increases the surface area in contact with prominent facial features such as the bridge of the nose and cheekbones by 30%-50% compared to traditional supports, effectively dispersing facial pressure and reducing the risk of skin redness or pressure sores caused by prolonged pressure. Furthermore, the top edge of the facial support platform 32 is equipped with a detachable U-shaped pillow fixing structure, such as Velcro fasteners or elastic rings distributed along the edge, which can fix a commercially available standard-sized U-shaped pillow, providing more options for patients who prefer to use auxiliary pads.

[0038] In some embodiments of this application, the support plate 1 is at least partially transparent, forming an observation area for the patient to view the status of the lower limb movement component 4. Specifically, a portion of the support plate 1 is made of transparent material to form the observation area. When the patient lies face down on the support plate 1, light can pass through the transparent observation area, allowing the patient's line of sight to see the lower limb movement component 4 below. This allows the patient to directly observe the position of their feet on the foot pedals 41, the swinging state of the foot pedals 41, etc., thus enabling real-time observation of their lower limb movements. The patient can see the status of the lower limb movement component 4 through the observation area, intuitively understanding their movement, such as whether the swing amplitude of the left and right foot pedals 41 is consistent, and whether their feet are correctly positioned on the foot pedals 41. This helps the patient adjust their exercise method in a timely manner, better control their lower limb movements, improve the accuracy and effectiveness of their exercise, and thus conduct lower limb training more scientifically.

[0039] In some other embodiments, the support plate 1 can be made entirely of a transparent material, depending on the requirements.

[0040] In some embodiments of this application, a grip ball 53 is provided at the outer end of the handle 52. Specifically, when the patient uses the upper limb movement component 5, their hand grips the grip ball 53 at the outer end of the handle 52. The grip ball 53 has a certain elasticity and friction. When the patient pulls the handle 52, the hand naturally applies grip force to the grip ball 53. During the pulling process, the elasticity of the grip ball 53 allows the hand to feel a certain reaction force. The reaction force stimulates the hand muscles to continuously adjust the force, while the friction between the hand and the grip ball 53 ensures that the hand will not easily slip during the pulling process, ensuring a stable connection between the hand and the handle 52, thereby allowing the patient to pull the handle 52 more effectively for upper limb movement. In addition, when the patient is not performing upper limb pulling exercises, they can use the grip ball 53 to perform grip training, which helps to enhance the grip strength of the hand and exercise the hand muscle groups.

[0041] In some embodiments of this application, such as Figure 5 and Figure 6As shown, two support frames 2 are provided, located on the bottom sides of the support plate 1 respectively. Each support frame 2 includes at least two support legs 21, with a connecting rod 22 between the two support legs 21. Each support leg 21 has a groove at its top, and the support plate 1 has a guide shaft 11 that slides through the groove. A lifting adjustment assembly 23 is provided between the support frame 2 and the support plate 1. Specifically, the two support frames 2 are located on the left and right sides of the bottom of the support plate 1 respectively. The two support legs 21 of each support frame 2 are connected by the connecting rod 22 to form a stable support structure. The guide shaft 11 at the bottom of the support plate 1 is inserted into the groove at the top of the support leg 21 to achieve a sliding connection, allowing the support plate 1 to move up and down. When the height of the support plate 1 needs to be adjusted, it is operated through the lifting adjustment assembly 23. After the lifting adjustment assembly 23 is activated, it drives the guide shaft 11 of the support plate 1 to slide up and down along the groove, thereby changing the height position of the support plate 1 to adapt to the needs of different patients' heights, usage habits, or different scenarios. In addition, the patient's feet can be placed on the connecting rods 22 of the two side support frames 2 to assist the patient in performing lower limb lifting exercises.

[0042] In other embodiments, the number of connecting rods 22 may be set to 1, 2 or 3 as required.

[0043] It should be noted that when the lower limb movement component includes a mounting frame 43, a rotating shaft 42, and a foot pedal 41, it provides the patient with wheel-like foot pedal movement, which also has the same effect of lower limb lifting during this movement. In this case, in order to ensure the stability of the support frame 2 foundation, the number of connecting rods 22 in a single support frame 2 can be set to one, eliminating the need for connecting rods 22 to assist the patient in lower limb lifting movements.

[0044] In some embodiments of this application, such as Figure 7As shown, the lifting adjustment assembly 23 includes a threaded cylinder 231 disposed on the support plate 1, a screw 232 installed inside the threaded cylinder 231, and a driver 233 disposed between the two support legs 21. The driver 233 is connected to the screw 232 and is used to drive the screw 232 to rotate and adjust the height position of the support plate 1. Specifically, when it is necessary to adjust the height of the support plate 1, the driver 233 between the two support legs 21 is activated. After the driver 233 operates, it drives the screw 232 connected to it to rotate. Since the screw 232 is installed inside the threaded cylinder 231 disposed on the support plate 1, according to the transmission principle of the thread, the rotation of the screw 232 will cause it to move axially within the threaded cylinder 231. When the screw 232 moves up or down, it will push the support plate 1 to rise or fall synchronously along the sliding groove at the top of the support leg 21, thereby achieving precise adjustment of the height position of the support plate 1. By utilizing the cooperation of the threaded cylinder 231 and the screw 232, and controlling the number of rotations and direction of the screw 232 via the actuator 233, the height of the support plate 1 can be precisely adjusted. This allows for personalized adjustments to meet the needs of different patients; for example, taller patients can raise the support plate 1, while shorter patients can lower it, making it more comfortable for them to maintain a downward-facing position while using the device. Using the actuator 233 to drive the screw 232 is much easier and more convenient than manually adjusting the height of the support plate 1. Patients or medical staff only need to activate the actuator 233 to adjust the height, eliminating the need to manually raise or lower the support plate 1 with considerable effort, thus reducing the difficulty and workload of adjustment.

[0045] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
