Description

Technical Field

[0001] This invention belongs to the field of medical assistive technology, specifically relating to a bedside standing training assistive device for ICU patients. Background Technology

[0002] ICU patients are prone to muscle weakness, reduced weight-bearing capacity in the lower limbs, and decreased balance during prolonged bed rest, postoperative recovery, or intensive care treatment. To promote early recovery, clinical nursing and rehabilitation training typically include bedside sitting, standing, and weight-bearing exercises tailored to the patient's physical condition. This allows patients to gradually transition from lying down and sitting to standing with the assistance of medical staff. Due to the weakened physical function of ICU patients and the limited space around the bed, standing training requires consideration not only of the stability of the patient's feet but also of the support provided by the upper limbs or torso during the standing process, in order to reduce the risk of falls, tilting, or insufficient support during training.

[0003] Existing bedside standing training aids in the ICU typically require adjustments by medical staff based on the patient's height, body type, foot placement, and bedside location. However, some aids lack adequate support adaptability when transitioning from a sitting to a standing position, making it difficult to achieve continuous and stable coordination between foot support, upper limb support, and the standing and lifting process. When patients have significant differences in body size or inconsistent foot placement angles, instability, mismatched support positions, or uneven force distribution during assisted standing can easily occur, affecting the safety and applicability of bedside standing training.

[0004] Therefore, existing bedside standing training assistive devices for ICU patients still have technical problems such as insufficient overall support adaptability for different patients during the bedside standing training process, making it difficult to stably meet the patient's needs for foot support, body support and assisted standing in a single training session. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a bedside standing training aid for ICU patients, which can solve the above problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An assistive device for bedside standing training in ICU patients includes a U-shaped board, a pedal, a lifting block, a horizontal plate, a rotating shaft, a support rod, and a gear. A column is mounted on the top rear side of the U-shaped board. The pedal is hinged to the front surface of the column and positioned inside the U-shaped board for the patient to step on with both feet. A support column is mounted on top of the column, and a lifting screw is installed inside the support column. The lifting block is slidably mounted inside the support column and screwed into the lifting screw. The horizontal plate is fixedly mounted on the front side of the lifting block. Rotating shafts are rotatably mounted on both sides of the horizontal plate. The front end of each rotating shaft is connected to a support rod via a swing arm, and a gear is mounted on the rear end of each rotating shaft. A gear is slidably mounted on the back of the horizontal plate, meshing with the gear. The gear is connected to a horizontal rod, which screws into a threaded rod to drive the gear and adjust the distance between the two support rods.

[0007] Furthermore, the U-shaped plate has a forward-opening U-shaped structure, and rollers are installed at the four corners of the bottom of the U-shaped plate. The rollers have a self-locking function, which is used to move the entire device to the side of the ICU bed and lock it in position during training.

[0008] Furthermore, the surface of the column is provided with a through groove, the surface of the pedal is provided with anti-slip texture, and a swing rod is fixed to the rear side of the rotating shaft of the pedal. The swing rod passes through the through groove and is used to swing as the angle of the pedal changes.

[0009] Furthermore, the end of the swing arm is hinged to a connector, and a lead screw is rotatably mounted on the surface of the connector. A knob is provided on the surface of the lead screw. An internal threaded cylinder is hinged to the back of the column. The end of the lead screw is screwed onto the internal threaded cylinder, which is used to drive the lead screw to rotate through the knob and adjust the distance of the lead screw extending out of the internal threaded cylinder, thereby adjusting the tilt angle of the pedal.

[0010] Furthermore, the support column is vertically fixed to the top of the column, the lifting screw is rotatably installed inside the support column, the lifting block is vertically slidably installed inside the support column, and the lifting block is screwed onto the lifting screw to drive the horizontal plate and support rod to rise and fall as a whole when the lifting screw rotates.

[0011] Furthermore, the horizontal plate is fixedly installed on the front side of the lifting block, the axis of the rotating shaft on both sides of the surface of the horizontal plate is horizontally set, the swing arm is set at the front end of the rotating shaft and located on the front surface of the horizontal plate, the support rod is fixed at the end of the swing arm, and the two support rods are arranged in parallel for the patient to rest their arm or for underarm support.

[0012] Furthermore, the gear is located at the rear end of the rotating shaft and on the back of the horizontal plate. Two racks are vertically slidably mounted on both sides of the back of the horizontal plate. The two racks mesh with the two gears respectively. The racks are installed in conjunction with the horizontal plate through a T-shaped groove.

[0013] Furthermore, an L-shaped connecting rod is provided at the top of the rack, the top of the L-shaped connecting rod extends forward, and a crossbar is fixed laterally between the tops of the two L-shaped connecting rods. A threaded rod is vertically and rotatably installed at the center of the upper surface of the lifting block, and the center of the crossbar is screwed onto the threaded rod, which is used to drive the crossbar to rise and fall when the threaded rod rotates, and to drive the two gears to rotate synchronously through the two racks.

[0014] Furthermore, the two racks are raised and lowered synchronously via a crossbar, the two gears rotate synchronously under the meshing action of the corresponding racks, and the two swing arms swing around the axis of their respective rotating shafts, so that the positions of the two support rods are adjusted synchronously to adapt to the support needs of patients of different body types.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention integrates a bedside positioning structure, a foot support structure, a lifting support structure, and a support spacing adjustment structure into a single unit, enabling the device to perform continuous coordination of positioning, foot pedaling, body support, and assisted standing at the ICU bedside. When the patient transitions from a sitting to a standing position, the foot pedal supports the patient's feet, the support rod supports the patient's upper limbs or armpits, and the lifting block drives the horizontal plate and support rod to rise and fall as a whole. This provides the patient with relatively continuous assisted support during a single bedside standing training session, solving the problem of insufficient overall support adaptability in existing bedside standing training aids.

[0016] This invention uses a footrest hinged to a column, along with a swing arm, connector, lead screw, knob, and internal threaded cylinder to create an adjustable footrest angle. This allows the footrest to be tilted according to the patient's foot position. When the patient places their feet on the footrest, the anti-slip texture on the surface enhances foot contact stability, preventing discomfort or instability during assisted standing that could hinder subsequent body lifting. This ensures the foot support is matched to the standing training process.

[0017] This invention utilizes the engagement of a lifting screw and a lifting block to enable the lifting block to drive the horizontal plate, rotating shaft, swing arm, and support rod to rise and fall as a whole. When the patient's arm rests on or under the armpit of the support rod, the support rod provides upward auxiliary support to the patient during the rising and falling motion. This allows the patient to transition from a sitting to a standing posture without relying entirely on manual assistance from medical staff, thus improving the coordination and stability between body support and lifting movements during bedside standing training.

[0018] This invention utilizes the transmission and coordination between threaded rods, crossbars, L-shaped connecting rods, racks, gears, rotating shafts, and swing arms to enable the two support rods to synchronously adjust their relative positions, accommodating the upper limb support or axillary support needs of patients with different body types. The two support rods remain linked during adjustment, reducing uneven force distribution caused by mismatched support distances on both sides, and ensuring a more stable overall fit for foot support, body support, and assisted standing, taking into account the patient's body shape.

[0021] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention. Example 1

[0022] See Figures 1 to 7An assistive device for bedside standing training for ICU patients includes a U-shaped board 1, a footboard 2, a lifting block 3, a horizontal plate 31, a rotating shaft 4, a support rod 43, and a toothed rod 5. The U-shaped board 1 serves as the base supporting the bottom of the device. The U-shaped board 1 has a U-shaped structure that opens forward. A column 12 is provided on the rear side of the top of the U-shaped board 1. The footboard 2 is hinged to the front surface of the column 12 and is located on the inner side of the U-shaped board 1. Before the patient performs bedside standing training, both feet can be placed on the footboard 2.

[0023] See Figure 1 , Figure 2 and Figure 3 A support column 14 is provided at the top of the column 12. The support column 14 is arranged vertically and a lifting screw 15 is provided inside the support column 14. The lifting block 3 is slidably disposed inside the support column 14 and is screwed to the lifting screw 15. The horizontal plate 31 is fixedly disposed on the front side of the lifting block 3. The horizontal plate 31 rises and falls synchronously with the lifting block 3, so that the support structure on the front side of the horizontal plate 31 can change height as the patient changes from a sitting posture to a standing posture.

[0024] See Figure 2 , Figure 5 and Figure 6 A rotating shaft 4 is rotatably mounted on both sides of the horizontal plate 31. A swing arm 42 is connected to the front end of the rotating shaft 4, and a support rod 43 is connected to the end of the swing arm 42. The two support rods 43 are arranged in parallel for the patient to rest their arm or for underarm support. A gear 41 is mounted at the rear end of the rotating shaft 4, and a toothed rod 5 is slidably mounted on the back of the horizontal plate 31. The toothed rod 5 meshes with the gear 41, and the toothed rod 5 cooperates with the threaded rod 311 through the crossbar 52. Thus, during the adjustment process, the gear 41, the rotating shaft 4, and the swing arm 42 are linked together, so that the distance between the two support rods 43 can be adjusted according to the patient's body shape.

[0025] In use, first move the U-shaped board 1 to the side of the ICU bed, so that the open side of the U-shaped board 1 faces the patient's position. After the patient sits on the edge of the bed, place both feet on the footrest 2. Then, adjust the tilt position of the footrest 2 according to the angle of the patient's feet to ensure stable support for the patient's feet. Subsequently, adjust the distance between the two support rods 43 according to the patient's shoulder width, upper limb support position, or underarm support position to adapt the two support rods 43 to the patient's body support position. After the adjustment is completed, the lifting screw 15 rotates and drives the lifting block 3 to rise and fall along the support column 14. The lifting block 3 drives the support rods 43 to rise and fall synchronously through the horizontal plate 31, the rotating shaft 4, and the swing arm 42, so that the patient can complete bedside standing training with the footrest 2 supporting the feet and the upper limbs or underarms supported by the support rods 43. Example 2

[0026] See Figures 1 to 4In scenarios where space is limited at the ICU bedside and patients have insufficient lower limb strength, the device needs to first complete bedside positioning and foot support. Rollers 11 are installed at the four corners of the bottom of the U-shaped board 1. The rollers 11 have a self-locking function, allowing the U-shaped board 1 to move to the ICU bedside via the rollers 11. Once in place, the rollers 11 lock, preventing the U-shaped board 1 from moving during training.

[0027] See Figure 1 and Figure 3 The upright column 12 is vertically installed on the top rear side of the U-shaped plate 1, and the pedal 2 is hinged to the lower front surface of the upright column 12, located on the inner side of the U-shaped plate 1. After the patient sits on the edge of the bed, both feet can be placed directly on the surface of the pedal 2. The surface of the pedal 2 is provided with anti-slip texture 21, which is distributed along the stepping area of ​​the pedal 2 to form an anti-slip contact between the patient's feet and the pedal 2.

[0028] See Figure 3 and Figure 4 The surface of the column 12 is provided with a through groove 13. A swing rod 22 is fixed to the rear side of the rotation shaft of the pedal 2, and the swing rod 22 passes through the through groove 13. When the angle of the pedal 2 around the hinge position of the front surface of the column 12 changes, the swing rod 22 swings synchronously with the rotation shaft of the pedal 2 in the through groove 13. The through groove 13 provides clearance for the swinging process of the swing rod 22, so that the angle adjustment action of the pedal 2 can be coordinated with the column 12. Example 3

[0029] See Figure 3 and Figure 4 When the foot placement angle varies among different patients, the tilt position of the pedal 2 needs to be adjusted. The end of the swing rod 22 is hinged to a connector 23, and a lead screw 24 is rotatably mounted on the surface of the connector 23. A knob 25 is provided on the surface of the lead screw 24. An internal threaded cylinder 26 is hinged to the back of the column 12, and the end of the lead screw 24 is screwed onto the internal threaded cylinder 26.

[0030] When adjusting the angle of pedal 2, the operating knob 25 causes the lead screw 24 to rotate, and the lead screw 24 extends or retracts relative to the internal threaded cylinder 26; the position change of the lead screw 24 is transmitted to the swing rod 22 through the connector 23, and the swing rod 22 drives the rotation axis of pedal 2 to swing, and the pedal 2 changes the tilt angle around the hinge position of the front surface of the column 12 with the rotation axis of pedal 2.

[0031] During the adjustment of pedal 2, the hinge relationship between connector 23 and swing rod 22 can adapt to the angle change of swing rod 22, and the hinge relationship between internal threaded cylinder 26 and back of column 12 can adapt to the angle change of lead screw 24, so that lead screw 24, connector 23, swing rod 22 and pedal 2 form a continuous transmission relationship. After pedal 2 is adjusted to a position suitable for the patient's feet to step on, the patient's feet are held on the surface of pedal 2, the anti-slip texture 21 is in contact with the soles of the feet, and the foot support base is formed during bedside standing training. Example 4

[0032] See Figure 1 , Figure 2 , Figure 3 and Figure 5 When a patient transitions from a sitting to a standing position, adjustable support is needed for the patient's upper limbs or armpits. A support column 14 is vertically fixed to the top of the column 12, a lifting screw 15 is rotatably mounted inside the support column 14, and a lifting block 3 is vertically slidably mounted inside the support column 14, screwed onto the lifting screw 15.

[0033] When the lifting screw 15 rotates, the lifting block 3 moves vertically along the support column 14. The horizontal plate 31 is fixedly installed on the front side of the lifting block 3, and the horizontal plate 31 rises and falls synchronously with the lifting block 3. Rotating shafts 4 are rotatably installed on both sides of the surface of the horizontal plate 31. The axis of the rotating shafts 4 is horizontally set, and a swing arm 42 is installed at the front end of the rotating shafts 4. The swing arm 42 is located on the front surface of the horizontal plate 31, and the support rod 43 is fixed to the end of the swing arm 42. The two support rods 43 are arranged in parallel.

[0034] The patient rests their arms on the two support rods 43, or positions the two support rods 43 under their armpits; then the lifting screw 15 moves the lifting block 3 upward, and the lifting block 3, through the cross plate 31, drives the rotating shaft 4, the swing arm 42, and the support rods 43 to rise as a whole. During the ascent, the support rods 43 provide support for the patient's upper limbs or armpits, allowing the patient to transition from a sitting to a standing posture while the footrest 2 supports their feet. Example 5

[0035] See Figures 5 to 7 When patients have significant differences in body size or different positions of their upper limbs, the distance between the two support rods 43 needs to be adjusted synchronously. A gear 41 is provided at the rear end of the rotating shaft 4, and the gear 41 is located on the back of the horizontal plate 31; two racks 5 are vertically slidably installed on both sides of the back of the horizontal plate 31, and the two racks 5 mesh with the two gears 41 respectively. The racks 5 are installed with the horizontal plate 31 through a T-shaped sliding groove, so that the racks 5 can slide vertically along the back of the horizontal plate 31.

[0036] See Figure 6 and Figure 7The top of the rack 5 is provided with an L-shaped connecting rod 51, the top of the L-shaped connecting rod 51 extends forward, and a crossbar 52 is horizontally fixed between the tops of the two L-shaped connecting rods 51. A threaded rod 311 is vertically and rotatably installed at the center of the upper surface of the lifting block 3, and the center of the crossbar 52 is screwed onto the threaded rod 311.

[0037] When adjusting the distance between the two support rods 43, the threaded rod 311 is rotated, and the crossbar 52 rises and falls under the rotation of the threaded rod 311; the crossbar 52 drives the two racks 5 to rise and fall along the back of the cross plate 31 synchronously through the two L-shaped connecting rods 51; when the two racks 5 rise and fall, they drive the corresponding gears 41 to rotate, the two gears 41 drive the corresponding rotating shafts 4 to rotate, and the two rotating shafts 4 then drive the corresponding swing arms 42 to swing around the axis of the rotating shafts 4, and the two swing arms 42 drive the two support rods 43 to change position synchronously.

[0038] After the spacing adjustment is completed, the two support rods 43 maintain a support distance that is adapted to the patient's body shape. When the patient is performing standing training, the two support rods 43 can simultaneously participate in upper limb support or axillary support. The cooperation between the toothed rod 5, gear 41, rotating shaft 4, and swing arm 42 ensures that the two support rods 43 maintain synchronous movement during the adjustment process, avoiding inconsistent adjustment of the support positions on both sides, which would affect the support coordination during the patient's bedside standing training.

[0039] The working principle of this invention is as follows: In use, the device is first moved to the side of the ICU bed by the rollers 11 at the four corners of the bottom of the U-shaped board 1, so that the front open side of the U-shaped board 1 is close to the patient's position. Then, the rollers 11 are self-locked to keep the U-shaped board 1 in a stable position during standing training. After the patient sits on the edge of the bed, he places his feet on the pedal 2. The pedal 2 is located inside the U-shaped board 1 and is hinged to the front surface of the column 12. The anti-slip texture 21 on the surface of the pedal 2 contacts the patient's soles to improve the stability of the patient's feet when stepping on it.

[0040] When it is necessary to adjust the tilt position of the pedal 2 according to the angle of the patient's feet, rotate the knob 25. The knob 25 drives the lead screw 24 to rotate relative to the internal threaded cylinder 26, so that the lead screw 24 extends or retracts into the internal threaded cylinder 26. During the change of position of the lead screw 24, the lead screw 24 drives the swing rod 22 to swing through the connector 23. The swing rod 22 passes through the through groove 13 on the surface of the column 12 and moves synchronously with the rotation axis of the pedal 2, thereby driving the pedal 2 to adjust the tilt angle around its hinge position with the column 12, so that the pedal 2 can fit the footing posture of the patient's two feet.

[0041] Next, the distance between the two support rods 43 is adjusted according to the patient's body shape. The threaded rod 311 is rotated, and since the center of the crossbar 52 is screwed into the threaded rod 311, the rotation of the threaded rod 311 drives the crossbar 52 to rise and fall. The crossbar 52 drives the two toothed rods 5 to slide synchronously vertically on the back of the cross plate 31 through the L-shaped connecting rods 51 on both sides. During the sliding process, the two toothed rods 5 mesh with the corresponding gears 41, so that the two gears 41 rotate synchronously. The gears 41 are set at the rear end of the rotating shaft 4. When the gears 41 rotate, they drive the rotating shaft 4 to rotate synchronously. The rotating shaft 4 then drives the swing arm 42 located on the front surface of the cross plate 31 to swing around the axis of the rotating shaft 4. The swing arm 42 drives the support rod 43 fixed at the end to change position, thereby adjusting the distance between the two support rods 43 so that the two support rods 43 can adapt to the arm resting or underarm support needs of patients of different body shapes.

[0042] After adjusting the angle of the pedal 2 and the spacing of the support rods 43, the patient rests their arm on the two support rods 43, or positions the two support rods 43 under the patient's armpit. Then, the lifting screw 15 inside the support column 14 is rotated. Since the lifting block 3 is screwed into the lifting screw 15 and is vertically slidably set inside the support column 14, the rotation of the lifting screw 15 drives the lifting block 3 to move up and down along the support column 14. When the lifting block 3 moves, it drives the horizontal plate 31 fixed at the front to rise and fall synchronously. The horizontal plate 31 then drives the two support rods 43 to rise and fall as a whole through the rotating shaft 4 and the swing arm 42, so that the support rods 43 provide upward auxiliary support for the patient's upper limb or armpit.

[0043] As the patient gradually transitions from a sitting to a standing position, both feet remain firmly planted on pedal 2. The anti-slip texture 21 restricts foot slippage, and pedal 2 provides stable support for the patient's feet through the aforementioned angle adjustment. Simultaneously, support rod 43 rises with the horizontal plate 31 and lifting block 3, providing auxiliary lifting for the patient's body, enabling the patient to complete standing training at the bedside. During training, the U-shaped plate 1 maintains overall positional stability through the locking mechanism of rollers 11, and the two support rods 43 maintain relative positional coordination through the synchronous cooperation of the rack 5, gear 41, rotating shaft 4, and swing arm 42, reducing the impact on the patient's standing stability caused by mismatched support distances on both sides.

[0044] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
