Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a multi-posture electric lifting downward-facing body positioning auxiliary device. Background Technology

[0002] In ophthalmic clinical nursing, some patients undergoing retinal surgery need to maintain a downward-facing position for an extended period post-surgery to utilize the buoyancy of gas or silicone oil to press against the retina and ensure surgical success. Currently, the most widely used assistive devices in clinical practice are prone pillows (for supine positions) and prone tables (for sitting positions). These devices are mostly static structures, with a fixed height for their support platform, or only very limited manual adjustments. The adjustment range cannot exceed the standard height for a sitting position, and their core function is to provide facial support for the patient in a single, fixed posture.

[0003] However, static and limited height adjustment cannot accommodate patients of different heights and various seat heights, resulting in unsatisfactory support postures and easily causing discomfort such as neck twisting and lower back unsupported. At the same time, the devices are functionally limited and generally lack consideration for standing positions, only supporting lying or sitting positions. Patients cannot distribute body pressure by changing positions, and maintaining a single posture for a long time can easily lead to lower back pain, numbness in the buttocks, and fatigue, reducing patient compliance. Utility Model Content

[0004] The purpose of this invention is to provide a multi-posture electric lifting downward-facing body positioning assistance device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-posture electric lifting face-down positioning auxiliary device, comprising: support columns, the bottoms of two support columns being connected to a U-shaped ground support, and the four corners of the U-shaped ground support being equipped with casters; a lifting mechanism, the lifting mechanism being disposed between the two support columns; a base plate, the base plate being fixedly mounted on the moving end of the lifting mechanism, and the surface of the base plate having a face-accommodating hole; a panel, the panel being rotatably connected to one side end of the base plate by at least one hinge, such that the panel can be flipped upwards to cover the face-accommodating hole to form a flat tabletop, or flipped downwards to expose the face-accommodating hole; and a foot support, the foot support being rotatably disposed between the two support columns and located above the U-shaped ground support via an angle adjustment mechanism.

[0006] In one feasible embodiment, the lifting mechanism includes: a rotating shaft, which is rotatably and laterally mounted between the two supporting columns, and a driven gear is fixedly mounted at each end of the rotating shaft; a driving member, which is fixedly mounted on the outside of one of the supporting columns through a housing, and a driving gear that meshes with the driven gear is mounted on the output shaft of the driving member; lifting columns, which are respectively movably disposed on the inner side of the supporting columns in a vertical direction, and the top ends of the two lifting columns are fixedly connected to the lower surface of the base plate; and racks, which are respectively vertically fixedly disposed on the inner side of the two lifting columns and mesh with the two driven gears respectively.

[0007] In one feasible implementation, the angle adjustment mechanism includes: an arc-shaped notch, two of which are symmetrically formed on the inner sidewalls of the two supporting columns, and their centers are coaxial; a connecting rod, both ends of which are rotatably connected to the ends of the foot support, and the connecting rod is configured as a hollow structure; limiting holes, a plurality of limiting holes being spaced apart along the arc-shaped trajectory of the arc-shaped notch on the inner side of the supporting column; and a locking assembly, which is housed in the internal cavity of the connecting rod and is used to selectively lock the connecting rod into different limiting holes.

[0008] In one feasible embodiment, the locking assembly includes: two insert rods movably disposed within an internal cavity along the axial direction of the connecting rod and selectively inserted into the limiting hole; two springs disposed within the internal cavity of the connecting rod and providing elastic force to the two insert rods; and a pressing member movably disposed at the middle of the connecting rod in a direction perpendicular to the axis of the connecting rod.

[0009] In one feasible implementation, two symmetrical abutment blocks with inclined surfaces are provided on the inner side of the pressing member; each of the insert rods has an abutment hole with a corresponding inclined surface at its end near the pressing member.

[0010] In one possible implementation, the panel and the base plate have completely identical planar dimensions and profile shapes at their opposite edges at the hinge connection.

[0011] Compared with existing technologies, the beneficial effects of this invention are as follows: This device achieves stepless adjustment of the panel and base plate from sitting height to standing height through a lifting mechanism, allowing patients to freely switch between various downward-facing positions. This effectively disperses the pressure generated by maintaining a single posture for a long time and completely avoids problems such as lower back pain and numbness in the buttocks caused by the fixed height of traditional static devices. Furthermore, the panel and base plate are of the same size and connected by hinges, allowing the device to quickly switch between positional assistance and daily desktop functions, greatly enhancing the practical value of the device and patient compliance. In addition, the locking component ensures smooth and effortless angle adjustment and reliable unlocking, significantly improving the convenience of operation and the durability of the mechanism. Through the comprehensive application of electrification and ergonomics, the device comprehensively improves the comfort, safety, and quality of life of postoperative patients during long-term downward-facing recovery.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1 to 4This utility model provides a technical solution: a multi-posture electric lifting face-down positioning auxiliary device, comprising: a support column 1, a lifting mechanism, a base plate 3, a panel 5, and a foot support 6. The bottoms of the two support columns 1 are connected to a U-shaped base support 2, and the four corners of the U-shaped base support 2 are equipped with casters (specifically, self-locking casters, not shown in the figure); the lifting mechanism is disposed between the two support columns 1; the base plate 3 is fixedly installed on the moving end of the lifting mechanism, and a face receiving hole 4 is opened on the surface of the base plate 3; the panel 5 is rotatably connected to one side end of the base plate 3 by at least one hinge, so that the panel 5 can be flipped upward to cover the face receiving hole 4 to form a flat tabletop, or flipped downward to expose the face receiving hole 4; the foot support 6 is rotatably disposed between the two support columns 1 through an angle adjustment mechanism and is located above the U-shaped base support 2.

[0016] It should be noted that during use, the postoperative patient first activates the lifting mechanism according to their desired downward-facing position (such as sitting or standing). The lifting mechanism drives its moving end to move vertically up and down, thereby causing the base plate 3 fixed on it to rise or fall smoothly to a suitable height. Then, the panel 5 is flipped so that the bottom surface of the panel 5 detaches from the upper surface of the base plate 3, fully exposing the face receiving hole 4 on the surface of the base plate 3. The patient places their face in the face receiving hole 4 to achieve a stable and comfortable downward-facing position. When the patient needs to eat, read, or perform other activities, the panel 5 can be flipped upward to completely cover the face receiving hole 4 of the base plate 3, thus forming a complete and flat tabletop for use. At the same time, the patient can also adjust the angle adjustment mechanism of the foot support 6 set between the support columns 1 to change the tilt angle or extension position of the foot support 6, ensuring that the legs are effectively supported, depending on whether they are sitting or standing.

[0017] When the entire device needs to be moved, patients or caregivers can easily push it to any desired location beside the bed, sofa, or in the room using the casters (not shown in the figure). This greatly facilitates the use of the device by patients with limited mobility after surgery in different living scenarios, avoiding the difficulties and risks associated with lifting heavy equipment. Each caster is equipped with a positioning mechanism, which can securely lock the casters to prevent any accidental movement when the patient leans on them, adjusts their posture, or adjusts their height. This ensures the absolute stability and safety of the device during use, fundamentally eliminating the safety hazards such as patient falls and positional shifts that may occur due to the device sliding.

[0018] In some examples, the lifting mechanism further includes: a rotating shaft 7, a driving component 9, lifting columns 12, and a rack 13. The rotating shaft 7 is rotatably and laterally mounted between two supporting columns 1, and a driven gear 8 is fixedly mounted at each end of the rotating shaft 7. The driving component 9 is fixedly mounted on the outside of one of the supporting columns 1 through a housing 10, and a driving gear 11 that meshes with the driven gear 8 is mounted on the output shaft of the driving component 9. The two lifting columns 12 are respectively movably mounted on the inside of the supporting columns 1 in the vertical direction, and the top ends of the two lifting columns 12 are fixedly connected to the lower surface of the base plate 3. The rack 13 is respectively vertically fixed on the inside of the two lifting columns 12 and meshes with the two driven gears 8 respectively.

[0019] It should be noted that when the patient operates the lifting switch, the drive component 9 is activated, its output shaft begins to rotate, and drives the active gear 11 fixed on it to rotate synchronously. The active gear 11 transmits power to the rotating shaft 7, which is fixedly mounted on the driven gear 8, through meshing with a driven gear 8, causing the rotating shaft 7 to rotate between the two support columns 1. The rotation of the rotating shaft 7 then drives another driven gear 8 fixed at its other end to rotate synchronously. The two rotating driven gears 8 respectively convert the rotational motion into linear motion through meshing with two racks 13 vertically fixed on the inner side of the lifting column 12, thereby driving the two lifting columns 12 to move synchronously and vertically upward or downward along the inner side of the support column 1. Finally, through the common fixed connection between the top of the two lifting columns 12 and the lower surface of the base plate 3, the height of the entire base plate 3 platform can be smoothly and precisely adjusted. The driving component 9, power supply, and control switch (such as a wired control panel or a wireless receiving module) form a complete electrical connection circuit via wires. The driving component 9 is preferably a servo motor or a stepper motor, and the control of the driving component 9 is a well-known technology in the field, and various mature implementation methods can be adopted.

[0020] For example, a wired control panel 5 with lifting control buttons can be installed on the outer wall of the support column 1 or the outer shell 10. It is electrically connected to the drive unit 9 via a cable, and the user can perform lifting operation by pressing the button.

[0021] Another preferred embodiment is to use a wireless remote control. The remote control is communicatively connected to the receiving module, which is electrically connected to the drive unit 9 and integrated inside the device. This allows the user to conveniently remotely control the raising and lowering of the device from a seated or standing position without moving their body. This is especially convenient for patients with limited mobility after surgery.

[0022] In some examples, the angle adjustment mechanism further includes: an arc-shaped notch 14, a connecting rod 15, a limiting hole 16, and a locking assembly. Two arc-shaped notches 14 are symmetrically opened on the inner sidewalls of the two supporting columns 1, and their centers are coaxial. The two ends of the connecting rod 15 are rotatably connected to the ends of the foot support 6, and the connecting rod 15 is configured as a hollow structure. Several limiting holes 16 are opened at intervals along the arc-shaped trajectory of the arc-shaped notch 14 on the inner side of the supporting column 1. The locking assembly is housed in the internal cavity of the connecting rod 15 and is used to selectively lock the connecting rod 15 in different limiting holes 16.

[0023] It should be noted that when the angle of the foot support 6 needs to be adjusted, the user first operates the locking component housed in the cavity inside the connecting rod 15 to release its locking constraint with the current limiting hole 16; then, external force is applied to the foot support 6, allowing the end of the connecting rod 15 to slide along the arc-shaped notch 14 coaxial with the center on the inner side wall of the support column 1; during this sliding process, the connecting rod 15 will drive the foot support 6 to rotate synchronously with its hinge point with the connecting rod 15 as the axis, thereby changing the tilt angle of the foot support 6; when the foot support 6 is adjusted to the target angle, that is, when the end of the connecting rod 15 slides to the position of another limiting hole 16 on the trajectory of the arc-shaped notch 14, the operation of the locking component is released, and the locking component will automatically reset under the action of its internal mechanism and embed into the new limiting hole 16, thereby firmly locking the connecting rod 15 and the connected foot support 6 at the new angle position.

[0024] In some examples, the locking assembly further includes: two insert rods 17, springs 18, and a pressing member 19. The two insert rods 17 are movably disposed within the internal cavity along the axial direction of the connecting rod 15 and can be selectively inserted into the limiting hole 16. The two springs 18 are disposed within the internal cavity of the connecting rod 15 and provide elastic force to the two insert rods 17. The pressing member 19 is movably disposed at the middle of the connecting rod 15 in a direction perpendicular to the axis of the connecting rod 15.

[0025] It should be noted that when the angle of the foot support 6 needs to be adjusted, the user applies a pressing force perpendicular to the axis of the connecting rod 15 to the pressing member 19, causing it to move inward into the connecting rod 15. The inner end of the pressing member 19 then presses the ends of the two insert rods 17, overcoming the elastic force provided by the spring 18, and driving the two insert rods 17 to move relative to each other along the connecting rod 15, so that their ends exit from the current limiting hole 16, thereby releasing the lock. At this time, the user can rotate the foot support 6 to the desired angle. When the foot support 6 rotates and drives the connecting rod 15 so that the insert rods 17 inside it are aligned with the new limiting hole 16, the pressing force on the pressing member 19 is removed, the spring 18 releases the stored elastic force, and pushes the two insert rods 17 to move in opposite directions along the axis, so that their ends are embedded in the new limiting hole 16, completing the lock, thereby firmly fixing the foot support 6 at the new angle position.

[0026] In some examples, the pressing member 19 is further provided with two symmetrical abutment blocks 20 with inclined surfaces on its inner side; each insert 17 has an abutment hole 21 with a corresponding inclined surface near the end of the pressing member 19. When the user applies force to the pressing member 19, the pressing member 19 moves along its axial direction, causing the two symmetrical abutment blocks 20 with inclined surfaces on its inner side to move synchronously. The inclined surface of each abutment block 20 then contacts the abutment hole 21 with a matching inclined surface at the end of the corresponding insertion rod 17 and generates relative sliding. Through the interaction of the inclined surfaces, the abutment hole 21 converts the linear motion of the pressing member 19 perpendicular to the axis of the connecting rod 15 into a mutual thrust applied to the two insertion rods 17, thereby driving the two insertion rods 17 to move relative to each other against the elastic force and realize disengagement from the limiting hole 16. When the pressing force is removed, the two insertion rods 17 return to their axial position under the action of elastic force, and their ends re-enter the limiting hole 16. At the same time, the insertion rods 17 apply a reverse force to the inclined surface of the abutment block 20 through the inclined surface of the abutment hole 21, pushing the entire pressing member 19 back to its initial position along its axial direction.

[0027] In some examples, the panel 5 and the base plate 3 have perfectly identical planar dimensions and contour shapes at their opposing edges at the hinge connection. When the device needs to be used as a tabletop, the user flips the panel 5 upwards, rotating it around the hinge axis until it completely covers the base plate 3. At this time, because the panel 5 and the base plate 3 have perfectly identical planar dimensions and contour shapes at their opposing edges at the hinge connection, the outer edge of the panel 5 and the outer edge of the base plate 3 are precisely aligned, forming a complete, continuous, and flat support plane. When the user needs to restore the face-down positioning assistive function, the user flips the panel 5 downwards, rotating it in the opposite direction around the hinge axis, thereby fully exposing the face-receiving hole 4 on the surface of the base plate 3, so that the patient can use it while prone.

[0028] In a preferred embodiment of this utility model, the electrical control system of the drive component 9 is further configured as follows: The electrical control system of the drive unit 9 includes the drive unit 9 as a power source, which is preferably a DC servo motor or stepper motor with a reducer; a DC power supply module that supplies power to the entire system, which can receive AC power or be directly powered by a built-in battery; and a user command input device.

[0029] The user command input device includes at least one of the following two possible implementations: Method 1: Wired control method A wired control panel is fixedly installed on the outer wall of one of the supporting columns 1 at a location easily accessible to the patient. This control panel has two physical buttons, "Up" and "Down," and a power indicator light. The control panel is electrically connected to a motor drive controller via an internal cable, which in turn is electrically connected to the drive unit 9. When the user presses the "Up" or "Down" button, a control signal is transmitted to the motor drive controller, which outputs corresponding direction and power signals to drive the motor to rotate forward or reverse, thereby achieving smooth raising and lowering of the base plate 3. Releasing the button stops the motor.

[0030] Method 2: Wireless remote control method: A wireless receiver module, such as a Bluetooth module, Wi-Fi module, or RF receiver module, is integrated inside the outer casing 10 or the supporting column 1. The user holds a separate wireless remote control, which also has "up," "stop," and "down" function buttons. When the user operates the remote control, the command signal is received and decoded by the wireless receiver module, and then the motor drive controller controls the movement of the drive component 9. This method is particularly convenient for postoperative patients with limited mobility to operate flexibly near a seated or standing position without having to exert effort to reach the device itself.

[0031] In addition, the control system can also integrate overcurrent protection circuits and mechanical limit switches. When the lifting column 12 reaches the upper or lower limit position, the limit switch is triggered, automatically cutting off the motor power supply to prevent the mechanism from overtravel and ensuring safe use.
