Description

Technical Field

[0001] This invention belongs to the field of postpartum rehabilitation assistive devices technology, specifically relating to a postpartum diastasis recti risk control training device and its usage control method that can be used on a bed to assist postpartum individuals in performing low-angle, progressive trunk lifting training. Background Technology

[0002] Postpartum rehabilitation typically emphasizes early, low-intensity, and gradual progression. For core muscle training, postpartum users performing trunk lifts, crunches, or similar movements in bed may experience discomfort and reduced adherence if the angle is too large, the movement too fast, the return is uncontrolled, or abdominal pressure is poorly managed. In current home settings, common practices involve using pillows, nursing bed backrests, or regular fitness equipment to assist training. However, these methods often lack visualization of angles for bed training, low-angle tiered locking, safe return control, and postpartum incision-friendly structures.

[0003] Existing adjustable-angle sit-up training devices are mostly geared towards general fitness enthusiasts. For example, adjustable-angle sit-up training devices typically use racks, gears, support rods, or electrically telescopic rods to change the backrest angle to adapt to different training intensities. These devices focus on floor exercise training and general abdominal muscle training, and their structure is relatively rigid. They usually do not consider the safety of soft bed surfaces, mattress slippage, starting at a small angle of 15° to 30° in the early postpartum period, angle display relative to the bed surface, incision avoidance, and sudden drop-off.

[0004] There are also obstetric and gynecological postpartum care auxiliary rehabilitation training devices, which mainly revolve around nursing beds, leg movement mechanisms, monitor height adjustment, entertainment and relaxation or limb circulation training. Their technical purpose is not to control the angle, speed and fall safety during postpartum trunk lifting training, nor do they integrate small angle grading, stage prompts, anti-cross-level adjustment, bed fixation and slow-fall damping into training equipment for the risk control of diastasis recti.

[0005] Therefore, it is necessary to provide an auxiliary device specifically designed for postpartum bed training, which can be reliably fixed on the bed surface, using the bed surface or base as an angle reference, supporting early low-angle fine adjustment of 15° to 30°, and reducing the risks of mis-adjustment, sudden drop and training compensation through locking, anti-accidental release, slow-descent damping and training stage prompts. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a postpartum diastasis recti risk control training device that can be used stably on a bed, can display and reliably lock the back support angle in small angles, and slowly fall back when released, while providing a usage control method to match the device.

[0007] To address the aforementioned technical problems, this invention provides a postpartum diastasis recti risk control training device. The training device includes a bed-supporting base, a back support board, an angle adjustment and locking assembly, an angle display assembly, a safety release and slow-descent assembly, a training phase prompt assembly, and optional lumbar and pelvic positioning components, handrails or straps, and a training recording assembly.

[0008] The bed support base is designed for placement on a bed surface, mattress, or nursing bed. The lower surface of the bed support base features an anti-slip layer, which can be made of silicone dots, rubber anti-slip strips, high-friction fabric, or a combination thereof. The bed support base also includes bed securing components, which may include one or more of the following: bed edge hooks, mattress-wrapping straps, adjustable-length webbing, quick-release buckles, and anti-slip strips. The anti-slip layer and the bed securing components work together to reduce slippage of the base relative to the bed surface during training.

[0009] A back support board is used to support the user's upper back, shoulder area, or part of the lumbar region. The back support board is connected to the bed support base via a hinged axis and can swing within a range of 0° to 90° relative to the bed support base. The back support board may include a rigid support frame and a removable soft pad, which can be configured with shoulder support areas, a lumbar transition area, and a breathable layer to balance support stability and comfort.

[0010] An angle adjustment locking assembly is positioned between the bed's support base and the back support plate. This assembly can be a combination of an arc-shaped tiered limiting plate and a locking pin that can be inserted into it, a rack and pinion, an adjustable support rod, a gas spring lock, a friction hinge, or a combination of these structures. Preferably, the angle adjustment locking assembly (i.e., on the arc-shaped tiered limiting plate) has locking positions corresponding to 15°, 20°, 30°, 45°, 60°, 75°, and 90°, or it can be a continuously adjustable locking structure with the aforementioned angle calibration ranges. The 15° to 30° range is the early low-angle training range, and the angle intervals within this range are preferably smaller than those in the medium-high angle range to allow for more precise early training angle control.

[0011] To reduce the risk of incorrect angle adjustments, this invention further incorporates a phased anti-skip-level mechanism. This mechanism can be a movable limit stop, a secondary release pin, a limit lever with elastic reset, or an electronic confirmation module. Without individual confirmation or secondary unlocking, the phased anti-skip-level mechanism only allows the back support plate to be adjusted from the current angle to an adjacent angle setting or an adjacent training interval, thereby reducing the risk of excessively large angles caused by skipping multiple settings at once.

[0012] An angle display component is used to display the relative tilt angle of the back support plate relative to the bed support base or bed surface. Since the bed surface may be tilted as a whole, for example, the head of a nursing bed may be slightly raised, displaying only the absolute angle of the back support plate relative to the horizontal plane may be inaccurate. Therefore, preferably, the angle display component includes a base reference member and a back plate follower member, and uses the relative angle between the two as the displayed angle. A mechanical angle display component can use a graduated arc plate and a pointer linked to the back support plate; an electronic angle display component can use tilt sensing units respectively disposed on the base and the back plate, with an angle processing unit calculating the difference between the back plate angle and the base reference angle.

[0013] The training phase prompt component works in conjunction with the angle display component to indicate the current angle as an early low-angle range, a mid-term transition range, or an advanced range, through scale color areas, text windows, mechanical sliding windows, electronic displays, indicator lights, or sound prompts. For example, 15° to 30° corresponds to the early low-angle range, 30° to 60° to the mid-term transition range, and 60° to 90° to the advanced range. Specific ranges can be adjusted according to product settings or medical guidance.

[0014] The safety release and slow-descent assembly includes an anti-accidental release mechanism and a slow-descent damping element. The anti-accidental release mechanism requires the user or caregiver to complete a first release action followed by a second release action to release the angle lock; examples include "pressing + flicking," "pulling + rotating," or "button confirmation + mechanical lever release." The slow-descent damping element can be a gas spring, rotary damper, hydraulic damper, or friction hinge, which provides damping during the descent of the back support plate to prevent sudden collapse. Preferably, the anti-accidental release mechanism is linked to the slow-descent damping element, ensuring the damping element is engaged before the lock is released.

[0015] The lumbar and pelvic positioning component is used to reduce the user's slippage on the bed or compensatory force exerted through the hips. The lumbar and pelvic positioning component can be a lumbar and pelvic support strap, thigh support strap, or pelvic positioning pad that connects to a bed support base or back support board. The lumbar and pelvic positioning component may feature tension limit indicators, flexible relief sections, and quick-release buckles. For users undergoing cesarean sections, the lumbar and pelvic positioning component or adjacent abdominal components may include incision avoidance windows, flexible decompression edges, or removable pressure dispersion pads to prevent concentrated pressure on the incision area.

[0016] Handrails or straps can be installed on both sides of the back support board or the bed support base to assist users in maintaining small, slow torso lifting movements. The handrails or straps can be equipped with markings indicating the range of motion, such as permitted stretching areas, warning areas, or grip positions, to remind users to avoid sudden, excessive lifting, or using too much leverage.

[0017] The training recording component may include an angle sensor, a counting module, a time recording module, a descent speed judgment module, and a prompting module. The training recording component records data such as the target angle, actual angle, number of training sessions, duration, and descent speed. When the actual angle exceeds the allowable deviation of the target angle, the descent speed of the back support plate exceeds a preset threshold, or the locking state is not confirmed, the training recording component can output visual, audible, or vibration prompts and limit further increases in the target angle.

[0018] Compared with existing technologies, the present invention has at least the following beneficial effects: First, the bed support base is equipped with both an anti-slip layer and a bed fixing component, which can improve stability on a flexible bed surface; Second, using the base or bed surface as an angle reference to display the relative angle of the back support board can reduce angle misjudgment caused by bed tilt; Third, the 15° to 30° low angle range uses more precise locking and display, which is suitable for early gradual training; Fourth, the stage anti-scraping mechanism reduces the risk of misoperation when adjusting the angle across stages; Fifth, the anti-accidental release and slow-descent damping linkage reduces the risk of the back support board suddenly falling back; Sixth, the waist and pelvis positioning, incision avoidance, and pressure dispersion structure improves postpartum comfort and compliance.

[0023] The embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the following embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention. Where there is no conflict, the structural features of the various embodiments can be combined with each other.

[0024] Example 1, like Figure 1 and Figure 2As shown, the training device in this embodiment includes a bed support base, a back support plate, a hinge shaft, an angle adjustment locking assembly, an angle display assembly, a safety release and slow-descent assembly, armrests or straps, and bed fixing components. The bed support base is a rectangular or folded plate structure with an anti-slip layer on its lower surface, which can be a silicone dot matrix or rubber strips. Bed fixing components are located on both sides of the bed support base, and the bed fixing components include straps that can bypass the mattress and bed edge hooks.

[0025] One end of the back support plate is connected to the bed support base via a hinged shaft. The angle adjustment locking assembly includes an arc-shaped stepped limiting plate and a locking pin. The arc-shaped stepped limiting plate is fixed to the bed support base or its side frame. The locking pin moves with the back support plate or support rod and can be inserted into the corresponding locking hole. The holes on the arc-shaped stepped limiting plate include 15°, 20°, 30°, 45°, 60°, 75°, and 90°, with the holes in the 15° to 30° range being more closely spaced to form an early, low-angle, fine locking mechanism.

[0026] The angle display component is a mechanical protractor, consisting of a dial fixed to the bed support base and a pointer linked to the back support plate. The dial is marked with angles from 0° to 90°, and Chinese prompts such as "early low angle," "mid-term transition," and "advanced" are provided at 15° to 30°, 30° to 60°, and 60° to 90°, respectively.

[0027] The safety release and slow-descent assembly includes an anti-accidental release mechanism and a slow-descent damping element. The anti-accidental release mechanism uses a combination of a push-button and a toggle handle; the handle can only be moved after the button is pressed to disengage the locking pin from its hole. The slow-descent damping element uses a rotary damper or a gas spring, located near the hinge axis or between the back support plate and the bed support base, to prevent the back support plate from rapidly falling back after the lock is released.

[0028] The stage-based anti-crossing mechanism can be a movable stop set on the arc-shaped grade limit plate. When the stop is in the initial position, the back support plate can only be adjusted within the range of 15° to 30°; after the caregiver or user completes the second unlocking, the stop moves to the allowed position, and the back support plate can enter the range of 30° to 60° or 60° to 90°.

[0029] Example 2, In another embodiment, the angle adjustment locking assembly uses a lockable gas spring to support the back support plate. The user releases the gas spring via a control handle to lock and adjust the angle of the back support plate. The angle display assembly employs an electronic structure, including a base reference member, a back plate follower, an angle processing unit, and a display / prompt window. The base reference member detects the reference angle α of the bed-supporting base or bed surface, the back plate follower detects the angle β of the back support plate, and the angle processing unit calculates the relative tilt angle θ = β - α and displays it in the display / prompt window.

[0030] By using the aforementioned relative angle display method, even when the head of the nursing bed is raised as a whole, the display / prompt window still shows the training angle of the back support board relative to the bed surface or base, rather than simply the absolute angle relative to the horizontal plane, thereby improving the accuracy of the training angle prompts on the bed. The display / prompt window can also display the current range, the next suggested level, the locking status, and the descent speed prompts.

[0031] Example 3, This embodiment further includes a lumbar and pelvic positioning component and armrests or straps. The lumbar and pelvic positioning component includes a lumbar and pelvic fixation belt and a pelvic positioning pad. A cutout avoidance window can be provided in the middle of the lumbar and pelvic fixation belt, and a flexible pressure-reducing edge is provided at the edge of the avoidance window. The lumbar and pelvic fixation belt also has tension limit indicators; when the tension exceeds the indicated range, it prompts the user to loosen the belt to avoid excessive pressure. Armrests or straps are located on both sides of the back support plate. The straps have allowable stretching areas and warning areas to facilitate user control of the range of motion.

[0032] The training recording component can be integrated with the angle display component. During user training, the training recording component records the target angle, actual angle, number of training sessions, and duration. If the actual angle exceeds the allowable deviation of the target angle, or if the back support plate's descent speed exceeds a preset threshold, the training recording component will issue a warning and can limit the next upward angle via electronic control or mechanical limits.

[0033] Training control methods like Figure 3 As shown, the training control method using the above-mentioned training device includes the following steps: S1, Placement and Fixing: Place the bed support base on the bed surface, ensuring the anti-slip layer adheres to the bed surface, and fix it to the mattress or bed edge using the bed fixing components.

[0034] S2, Angle Calibration: Zero or calibrate the angle display component with the bed support base or bed surface as a reference, so that the display angle is the relative tilt angle of the back support plate with respect to the bed surface or bed support base.

[0035] S3, Set Target Angle: Select the target angle according to the training stage. The early low-angle training range is preferably 15° to 30°, and 15°, 20° or 30° can be selected as the target angle; then, after professional guidance or when preset conditions are met, you can gradually enter the intermediate transition range of 30° to 60° or the advanced range of 60° to 90°.

[0036] S4, Adjust and Lock: Adjust the back support plate to the target angle, lock it using the angle adjustment locking component, and confirm the current relative tilt angle using the angle display component. If a staged anti-crossing mechanism is provided, perform a separate confirmation or secondary unlocking before crossing the training zone.

[0037] S4-1, Relative Angle Judgment: In the electronic embodiment, the base reference component obtains the bed surface reference angle α, the back plate follower obtains the back plate angle β, and the angle processing unit calculates the relative tilt angle θ=β-α; when θ does not fall within the allowable deviation range of the target angle, the display / prompt window outputs an adjustment prompt until the angle adjustment locking component completes locking.

[0038] S5, Training Tips and Records: The training phase prompt component displays the current training phase, target angle, and next suggested gear; the training record component records the number of training sessions, duration, and descent speed; the handrail or strap 8 indicates the range of motion.

[0039] S6, Safe Exit: When training is over or when it is necessary to lower the angle, first complete the two consecutive release actions specified by the anti-accidental release mechanism to release the lock. At the same time, the slow-descent damping component provides damping, and the back support plate slowly falls back to a low angle or horizontal position.

[0040] In the description of this invention, it should be understood that the terms "center," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0041] In this invention, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection; a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of these terms in this invention according to the specific circumstances.

[0042] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
