Description

Technical Field

[0001] This invention relates to the field of rehabilitation therapy equipment technology, specifically to an oblique prone inverted traction method and its self-service lumbar traction device. Background Technology

[0002] With the increasing prevalence of spinal disorders such as lumbar degenerative diseases, lumbar muscle strain, and lumbar disc herniation, lumbar traction, as a non-surgical intervention, has been widely used in clinical rehabilitation and home care. Traditional lumbar traction devices are mostly large hospital traction beds or specialized physiotherapy equipment. While these devices provide stable traction force and angle control, they generally suffer from being bulky, complex to operate, and requiring professional adjustment, making it difficult to meet the needs of patients for daily self-traction at home. Especially for those requiring long-term home rehabilitation, frequent trips to medical institutions not only increase time and financial costs but may also delay traction, affecting rehabilitation outcomes. Therefore, there is a clear market demand for lightweight, easy-to-operate, more effective, and self-controlled home lumbar traction devices.

[0003] Currently, home-use lumbar traction products on the market mainly fall into two categories: one is simple traction belts or slings, which achieve traction by suspending heavy objects or pulling manually. However, these products lack a stable support platform, resulting in short traction times, poor effects, and problems such as body slippage and uneven traction force. Furthermore, they cannot precisely control the traction direction, and long-term use may increase the burden on the lower back due to improper force. The other category is fixed traction brackets, which provide some support, but generally use a rigid connection structure, cannot be folded for storage, occupy a large space, and have limited height and length adjustment functions, making it difficult to adapt to the needs of patients of different heights and body types, and incompatible with various placement scenarios such as beds and floors. In addition, the fixing devices of existing products mostly use Velcro or simple buckles, which have insufficient friction with the body, making it easy for the straps to loosen or the body to shift during traction, thus reducing the traction effect or even causing secondary injury.

[0004] While some existing technologies have attempted to improve upon the aforementioned issues, significant limitations remain. For instance, some traction boards, despite adding handrails, fail to consider the natural arm angles of patients in a prone position, resulting in insufficient grip stability. Some designs feature extendable legs, but the adjustment process is cumbersome, requiring tools for disassembly and locking, hindering quick height adaptation. Others employ a flat structure, which, while foldable, fails to address the issue of excessive thickness and inconvenience when folded, and lacks anti-accidental opening design at the hinges, posing a storage safety hazard. Regarding strap fixation, most products use only open grooves for the straps, without adaptable structures for different strap widths. The smooth groove walls lack anti-slip treatment, often leading to strap slippage and fixation failure during actual use.

[0005] From a user experience perspective, an ideal home-use lumbar traction device must simultaneously meet three core requirements: "safety and stability," "convenience and adjustability," and "comfortable fit." Patients need to perform traction while lying prone, requiring them to move themselves, which places higher demands on the device's support stability and posture maintenance capabilities. Furthermore, family members may have differences in age and physical strength, necessitating an intuitive operating logic and error-tolerant design. In addition, ergonomic details that are frequently touched (such as the anti-slip properties of the straps, the grip feel of the handles, and the shock absorption of the support legs) directly affect user compliance and safety. However, existing products still have significant room for improvement in structural integration and functional refinement, particularly lacking a design scheme that organically integrates functions such as folding and storage, multi-directional adjustment, and anti-slip fixation, making it difficult for users to balance "effective traction" and "ease of use." Summary of the Invention

[0006] The purpose of this invention is to provide a prone traction method with a tilted position and a self-service lumbar traction device. The design incorporates a two-section folding telescopic traction plate and a telescopic fixing groove for the straps, facilitating patient self-operation. The combination of a slide rail, sliding plate, telescopic support legs, and pulleys enhances stability and mobility, meeting the needs of different body types and usage scenarios, and improving the safety and comfort of lumbar traction. The prone traction method differs from the supine traction method, making it more conducive to the repositioning of the lumbar disc herniation.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a method for inclined prone suspension traction and a self-service lumbar traction device, comprising a two-section folding telescopic traction plate. The upper end of the two-section folding telescopic traction plate is provided with a strap telescopic fixing groove, and the end face of the strap telescopic fixing groove is provided with a strap. The strap telescopic fixing groove extends from one side of the upper end of the two-section folding telescopic traction plate to the other side, forming a long strip-shaped through structure. The groove depth is sufficient to accommodate the strap part being embedded without affecting the strap's pull-out adjustment. The groove width gradually narrows from the outside to the inside, forming a guiding slope, which facilitates the strap to be quickly aligned with the groove and pushed in for fixation. One end of the strap is fixed to the end face of the groove, and the other end is a free end with a D-ring adjustment buckle. The user can pull the free end to adjust the length according to their own ankle circumference. After adjustment, the strap is locked by the D-ring buckle, so that the strap can closely fit the ankle contour. Combined with the limiting function of the groove, it maintains the relative fixation of the foot and the traction plate during traction, avoiding the influence of foot slippage on the transmission of traction force to the lumbar spine.

[0008] Furthermore, the upper end of the two-section folding telescopic traction board is provided with a slide rail, the end face of which is provided with a slide plate, and the upper end of the two-section folding telescopic traction board is provided with a hand grip. The slide rail is arranged parallel to the longitudinal center line of the upper end of the two-section folding telescopic traction board and perpendicularly intersects the length direction of the strap telescopic fixing groove, forming a cross-shaped layout to constrain the displacement of the feet and the upper body respectively. The two ends of the slide rail extend to the upper edge of the traction board to ensure that the slide plate is supported by the track during the entire sliding stroke and will not come off. The slide plate is located at the end of the slide rail near the head of the traction board, and its initial position is close to the starting point of the slide rail. When the user is lying down, it can slide backward to adjust to a suitable position below the abdomen. The hand grip is set in the upper area of ​​the slide rail near the slide plate. The distance between the hand grip and the slide plate allows the elbows to naturally rest against the surface of the traction board when the hands are gripping, forming a stable force fulcrum to assist in completing the sliding adjustment of the slide plate or the action of getting up.

[0009] Furthermore, the lower end of the two-section folding telescopic traction plate is provided with telescopic support legs, and the lower end of each telescopic support leg is provided with a pulley. There are two telescopic support legs, symmetrically distributed on the left and right sides of the lower end of the two-section folding telescopic traction plate. Each support leg is composed of two sleeves, inner and outer, with the inner sleeve sliding up and down inside the outer sleeve. The pulley is installed at the lower end of each telescopic support leg, corresponding to each support leg. When the telescopic support leg is extended, the pulley is lowered to contact the support surface. When it is shortened, the pulley is raised and suspended in the air, ensuring that the traction device can maintain stable contact at the bottom under different support scenarios. At the same time, the rolling characteristics of the pulley enable convenient movement of the traction device.

[0010] Furthermore, the strap telescopic fixing groove extends laterally along the upper end of the two-section folding telescopic traction plate. The groove width is adapted to the embedding of straps of different widths. The inner side of the groove wall has shallow textures to enhance the anti-slip properties of the strap during fixation, ensuring that the strap is firmly connected to the patient's ankle and does not loosen. The width of the groove gradually narrows from the groove opening to the bottom of the groove. The minimum width is slightly larger than the thickness of the strap body, and the maximum width can accommodate the thickness of two layers of folded strap, so that straps of different widths can be smoothly embedded and will not wobble in the groove. The shallow textures on the inner side of the groove wall are composed of evenly distributed fine protrusions. The height of the protrusions is 0.5 mm to 1 mm, and the spacing is no more than 2 mm. When the strap is embedded in the groove, the protrusions are in direct contact with the surface of the strap. By increasing the micro-roughness of the contact surface, the static friction is improved. Even if the strap is repeatedly pulled during traction, it can maintain a firm fit with the groove wall and avoid ankle fixation failure due to strap slippage.

[0011] Furthermore, the slide rail is a long, narrow groove longitudinally formed along the upper end of the two-section folding telescopic traction plate. Its length is greater than the maximum sliding stroke of the skateboard. The edges of the groove are rounded to prevent the skateboard from scraping against the groove during sliding, ensuring a smooth and stable sliding process. The length of the slide rail is 15 centimeters longer than the distance the skateboard slides from the starting position to the farthest point, ensuring that the skateboard is always fully contained within the groove during the entire sliding process, without jamming due to overtravel. The rounded radius of the groove edge is 2 to 3 millimeters, resulting in a smooth, burr-free edge. When the bottom surface of the skateboard contacts the edge of the groove, the rounded corner structure can disperse local pressure and eliminate the sharp frictional resistance generated by direct contact between metal or hard materials, allowing the skateboard to be subjected to only uniform sliding friction force when pushed or pulled back, achieving linear and stable movement.

[0012] Furthermore, the skateboard is a flat structure that matches the slide rail. Its bottom surface has raised sliders that slide against the inner wall of the slide rail. The surface of the skateboard is treated with a frosting process to form a fine textured surface, increasing the friction when in contact with the patient's body and preventing the body from shifting during sliding. The raised sliders are two parallel strip-shaped protrusions, symmetrically arranged on the front and back sides of the bottom surface of the skateboard, precisely matching the width of the inner wall of the slide rail. The height of the sliders is consistent with the groove depth of the slide rail, ensuring that a small gap is maintained between the bottom surface of the skateboard and the bottom surface of the slide rail, avoiding direct friction damage to the slide rail. The frosted texture on the surface of the skateboard consists of evenly distributed fine granular protrusions, with a particle height not exceeding 0.3 mm, covering the entire plane in contact with the body. When the patient lies prone and places their abdomen or chest against the skateboard, the texture can embed into clothing fibers or the skin surface, forming a multi-point contact fixation effect. Even if the skateboard shakes slightly during adjustment, it can effectively inhibit the tendency of the body to slide.

[0013] Furthermore, the main support structure can be placed at an overall angle to form an oblique support structure, the angle of which can be adjusted, and the maximum angle of inclination does not exceed 15 degrees.

[0014] Furthermore, the supporting component is located in the upper region of the main support structure to support the user's upper body when lying prone during operation.

[0015] Furthermore, the component for gripping with both hands is fixedly mounted on one side of the upper part of the main support structure, allowing the user in a prone position to grip it with both hands.

[0016] Furthermore, the restraint straps are designed to be installed and fixed at a position that fits the user's ankle or calf.

[0017] This invention provides a method for inclined prone suspension traction and a self-administered lumbar traction device, which has the following beneficial effects: 1. Stable strap fit and connection This design incorporates a laterally extending strap telescopic fixing groove at the upper end of a two-section folding telescopic traction plate. The groove width accommodates straps of varying widths, enhancing both versatility and personalized fit. The shallow textured design on the inner side of the groove effectively increases static friction with the strap, preventing accidental loosening due to stress or sweat during traction. The strap itself secures the patient's ankle or lower leg, and its scientifically designed position ensures effective traction on the distal lower limbs. This series of design elements collectively ensures a secure and reliable connection between the patient's body and the traction device (ankle / lower leg) in an inverted, prone position, fundamentally eliminating the risk of slippage. This provides a fundamental safety guarantee for long-term, stable traction treatment, significantly improving both safety and effectiveness.

[0018] The sliding rails and slide plates work together to ensure stability and smoothness. The core sliding mechanism consists of a long, longitudinally positioned slide rail at the top of the traction board that precisely engages with a sliding plate with raised sliders on the bottom. The length of the slide rail is calculated to exceed the maximum sliding stroke of the sliding plate, providing ample space for the body to naturally descend during traction. The rounded edges of the slide rail grooves prevent scratching or obstruction of the sliding plate sliders at the edges, ensuring a smooth and seamless sliding process. Simultaneously, the surface of the sliding plate undergoes a frosted process, creating a uniform and fine texture that significantly increases friction between the plate and the patient's prone upper body (usually the chest and abdomen). This ingenious "smooth on the bottom, rough on the top" design ensures that the patient's body slides smoothly along the slide rails under gravity to generate continuous traction, while preventing unnecessary lateral or forward / backward displacement of the body on the sliding plate surface, thus ensuring a stable and accurate traction posture.

[0019] Adjustable tilt angle achieves natural gravity traction. The two-section folding telescopic traction board can be tilted as a whole, forming an inclined structure with the feet higher than the head, and its tilt angle can be adjusted according to the patient's tolerance and traction needs (maximum not exceeding 15 degrees). When the patient is placed on it in a prone position, the weight of the upper body generates a downward traction force along the inclined board surface. This traction force is transmitted through the torso to the lumbar spine, forming a continuous and gentle longitudinal stretching force. This method, which uses the patient's own weight as the primary traction source, is completely in line with the principles of human biomechanics and avoids muscle resistance and secondary injuries that may be caused by external mechanical forceful traction. The controllable angle design allows the magnitude of the traction force to be increased stepwise and gradually, making it easy for the patient to adapt and more safely and effectively opening the lumbar intervertebral space, creating space for intervertebral disc decompression and structural repositioning.

[0020] The handle provides active assistance and support. A hand grip is fixed to one side of the upper part of the traction board, providing a stable gripping point for patients in a prone position. During traction, patients can actively grip and slightly pull the handle upwards (towards the head) to apply an auxiliary pulling force to the upper body in the opposite direction of gravity traction. This action not only further enhances the stretching effect on the lumbar spine, achieving "superposition" and autonomous fine-tuning of the traction force, allowing patients to find the most suitable traction intensity based on their real-time sensation; more importantly, it provides a strong support point for the upper limbs, helping patients better control their body balance on the inclined board, stabilize their core posture, and alleviate neck or shoulder discomfort that may result from prolonged prone position, thus significantly enhancing the comfort, controllability, and overall therapeutic effect of the traction process.

[0021] Multiple traction postures integrated to improve treatment flexibility This device's ingenious structural design integrates three traction postures—oblique, prone, and inverted—into one. By adjusting the support legs to change the tilt angle, selecting straps to secure the ankles or lower legs, and using hand grips, patients can achieve different traction modes on a single body position. For example, the oblique position combines sliding with a skateboard to fully utilize gravity; the simple prone position is suitable for initial adaptation or gentle traction; while the inverted position, with the ankles securely strapped, allows for longer-term continuous traction. This integrated design, combining natural gravity traction with simple mechanical assistance, breaks through the traditional single mode of supine traction, especially making traction in the prone position possible, which is believed to be more beneficial for the reduction of certain types of herniated discs. It greatly improves the flexibility and practicality of traction therapy, meeting the personalized rehabilitation needs of patients at different stages of disease, with different symptom characteristics, and different tolerance levels.

[0025] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0027] How to use: First, the user needs to unfold the two-section folding telescopic traction plate 1 from its folded state and secure it with the locking device in the middle, ensuring that both sections remain straight and stable. After unfolding, adjust the length of the telescopic support leg 7 according to the required height of the placement location, and lock it in the appropriate position with the pins to keep the two-section folding telescopic traction plate 1 level and prevent tilting from affecting the traction effect. Then, use the pulley 8 at the lower end of the telescopic support leg 7 to move the traction device to the usage position. The rubber tread of the pulley 8 reduces noise during movement and ensures flexible steering. Once in place, it is ready for use.

[0028] Next, the user should lie face down on the upper part of the two-section folding telescopic traction board 1, adjusting their body position so that their waist roughly corresponds to the middle folding hinge of the two-section folding telescopic traction board 1, so that the traction force can be concentrated on the lumbar spine. While lying face down, the user can adjust their lower body appropriately so that their ankle can be easily placed into the strap 3 within the strap telescopic fixing groove 2. The strap telescopic fixing groove 2 extends laterally along the upper end of the two-section folding telescopic traction board 1. The shallow grooves on the inner side of the groove wall enhance the anti-slip properties of the strap 3 when fixed. After wrapping the strap 3 around the ankle, the user can adjust the tightness according to their own comfort, ensuring that the strap 3 is securely connected to the ankle and does not loosen.

[0029] After securing the ankles, the user can grip the handles 6 with both hands. The handles 6 are cylindrical grips, vertically fixed to the upper end of the two-section folding telescopic traction board 1 near the skateboard 5. Their height is adapted to the natural gripping position of an adult's arms when lying prone, facilitating stable force application. After gripping the handles 6, the user can slowly move their body along the length of the two-section folding telescopic traction board 1 by pulling with their arms, according to their own strength and traction needs. At this time, the skateboard 5 will slide along the slide rail 4, which is a long, longitudinal groove along the upper end of the two-section folding telescopic traction board 1. Its length is greater than the maximum sliding stroke of the skateboard 5, ensuring smooth sliding throughout the traction process. The raised sliders on the bottom of the skateboard 5 fit snugly against the inner wall of the slide rail 4, preventing significant resistance during sliding. The rounded edges of the groove further prevent scratching between the skateboard 5 and the groove, making the sliding process even smoother.

[0030] During the gliding process, the frosted surface of the skateboard 5 creates a fine textured surface, increasing friction with the patient's body and preventing displacement, ensuring the traction force is accurately applied to the lumbar region. Users can control the gliding distance and traction intensity based on their own comfort, achieving self-traction of the lumbar spine through repeated pulling and relaxing. During traction, the strap 3, secured by the strap's telescopic locking groove 2, keeps the lower body stable, while the movement of the upper body provides continuous and controllable traction to the lumbar spine, thereby stretching the intervertebral space and relieving lumbar muscle tension.

[0031] The traction device is best placed beside the bed. After traction, the user can slowly relax their arms to return to the initial position, then untie the straps 3, get up from the two-section folding telescopic traction board 1, and lie down to rest. The traction device can also be moved back to its storage position using the pulleys 8. To save space, the telescopic legs 7 can be retracted to their shortest length, and the two-section folding telescopic traction board 1 can be folded into a snug position and locked with the locking device to prevent accidental unfolding. The folded two-section folding telescopic traction board 1 is less than half the thickness of its unfolded state, making it easy to store and carry.

[0032] Example: Example 1 This embodiment provides a prone traction method with a tilted placement and a self-service lumbar traction device, mainly composed of a two-section folding telescopic traction plate 1. The upper end of the two-section folding telescopic traction plate 1 is provided with a strap telescopic fixing groove 2, and a strap 3 is installed on the end face of the strap telescopic fixing groove 2. The strap telescopic fixing groove 2 extends laterally along the upper end of the two-section folding telescopic traction plate 1, and its width can accommodate straps 3 of different widths. The inner side of the groove wall has shallow textures to enhance the anti-slip properties of the strap 3 during fixation, ensuring a stable connection between the strap 3 and the patient's ankle. The middle of the two-section folding telescopic traction plate 1 has an openable and closable folding hinge. The two sections of the plate are connected by the hinge and can be folded to a close-fitting state. The thickness of the folded plate is less than half that of the unfolded state. A locking device is provided at the hinge to lock it after folding to prevent accidental unfolding. In use, the user lies prone on the two-section folding telescopic traction plate 1, fixes their ankle in the strap 3, and achieves lumbar traction through their own upper limb strength.

[0033] Example 2 This embodiment further optimizes the structure based on Embodiment 1. A slide rail 4 is provided at the upper end of the two-section folding telescopic traction plate 1, and a sliding plate 5 is provided on the end face of the slide rail 4. The slide rail 4 is a long, narrow groove longitudinally formed along the upper end of the two-section folding telescopic traction plate 1, with a length greater than the maximum sliding stroke of the sliding plate 5. The edges of the groove are rounded to prevent the sliding plate 5 from scraping against the groove, ensuring smooth and stable sliding. The sliding plate 5 is a flat plate structure that matches the slide rail 4. Its bottom surface has raised sliders that slide against the inner wall of the slide rail 4. The surface of the sliding plate is treated with a frosted process to form a fine textured surface, increasing friction when in contact with the patient's body and preventing body displacement during sliding. A hand grip 6 is also provided at the upper end of the two-section folding telescopic traction plate 1. The hand grip 6 is a columnar grip structure, vertically fixed to the upper end of the two-section folding telescopic traction plate 1 near the sliding plate 5. The outer periphery of the grip is covered with a flexible anti-slip layer, and its installation height is adapted to the natural bending position of an adult's arm when lying prone, facilitating stable application of force with both hands. When the user lies face down, their body is in contact with the skateboard 5, and they hold the handles 6 with both hands to pull the skateboard 5 along the slide rail 4, thereby achieving lumbar traction.

[0034] Example 3 This embodiment adds a support and adjustment structure to the first embodiment. The lower end of the two-section folding telescopic traction plate 1 is equipped with a telescopic support leg 7, and the lower end of the telescopic support leg 7 is equipped with a pulley 8. The telescopic support leg 7 is a sleeve assembly that can vertically extend and retract along the lower end of the two-section folding telescopic traction plate 1. The outer wall of the sleeve has multiple sets of annular positioning holes, and the telescopic length is locked by pins to adapt to the support needs of beds or floors of different heights, ensuring the traction device is placed stably. The pulley 8 is vertically installed at the lower end of the telescopic support leg 7 via an axle. The outer circumference of the pulley is covered with a rubber tread, and its diameter is proportional to the thickness of the telescopic support leg 7, ensuring flexible steering when moving the traction device while avoiding excessive noise or wear when in contact with the ground. In use, the length of the telescopic support leg 7 can be adjusted according to the height of the placement position to keep the two-section folding telescopic traction plate 1 horizontal, and then the traction device can be moved to a suitable position via the pulley 8, improving ease of use.

[0035] Example 4 This embodiment combines the structural features of embodiments two and three. The upper end of the two-section folding telescopic traction board 1 is equipped with a slide rail 4, a slide plate 5, and a handle 6, while the lower end is equipped with telescopic support legs 7 and pulleys 8. The strap telescopic fixing groove 2 extends laterally along the upper end of the two-section folding telescopic traction board 1. The strap 3 is installed on the end face of the strap telescopic fixing groove 2. The shallow texture on the inner side of the groove wall enhances the anti-slip properties of the strap 3, ensuring a stable ankle fixation. The slide rail 4 is a long, narrow groove with rounded edges. The raised slider on the bottom surface of the slide plate 5 slides against the inner wall of the slide rail 4. The frosted texture on the surface of the slide plate prevents body displacement. The handle 6 is vertically fixed to the upper end of the two-section folding telescopic traction board 1 near the slide plate 5, facilitating stable application of force by the user's hands. The telescopic support legs 7 can extend and retract vertically and are locked by pins. The pulleys 8 allow for flexible movement of the traction device. The user lies prone on the skateboard 5 with their ankles secured in the straps 3. They hold the handles 6 with both hands and pull their body to make the skateboard 5 slide along the rails 4, thus achieving lumbar traction. At the same time, the length of the telescopic support legs 7 and the position of the traction device can be adjusted as needed.

[0036] Example 5 This embodiment further improves the overall structure based on the above embodiment. The middle part of the two-section folding telescopic traction board 1 is provided with an openable and closable folding hinge and locking device, which can be folded to a close-fitting state for easy storage and carrying. The upper end of the two-section folding telescopic traction board 1 is provided with a strap telescopic fixing groove 2 and a strap 3. The inner side of the groove wall of the strap telescopic fixing groove 2 is provided with shallow texture to enhance the anti-slip properties of the strap 3. The upper end is also provided with a slide rail 4 and a slide plate 5. The edge of the groove of the slide rail 4 is rounded and polished. The raised slider on the bottom surface of the slide plate 5 slides in close contact with the inner wall of the slide rail 4. The surface of the slide plate is treated with a frosted process to prevent body displacement. The handle 6 is vertically fixed to the upper end of the two-section folding telescopic traction board 1 near the slide plate 5 for easy application of force by the user. The lower end of the two-section folding telescopic traction board 1 is provided with a telescopic support leg 7 and a pulley 8. The telescopic support leg 7 can be extended and retracted vertically and locked by a pin. The pulley 8 can flexibly move the traction device. In use, the user unfolds and locks the two-section folding telescopic traction board 1, adjusts the length of the telescopic support legs 7, moves the traction device to a suitable position, lies prone on the skateboard 5, secures the ankles in the straps 3, and holds the handles 6 with both hands to pull the body, causing the skateboard 5 to slide along the rails 4 to achieve lumbar traction. After traction, the traction device can be folded and stored, improving the convenience and flexibility of use.
