Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a standing bed for rehabilitation training. Background Technology

[0002] Standing beds are commonly used rehabilitation equipment in the process of lower limb rehabilitation training. However, most standing beds in the current technology only have the function of lower limb auxiliary rehabilitation training and lack the function of upper limb training. They cannot meet the needs of patients for comprehensive rehabilitation training. Some patients need not only lower limb strength and coordination training, but also upper limb exercise to restore muscle strength and joint mobility during the rehabilitation process.

[0003] The purpose of this invention is to provide a standing bed for rehabilitation training to solve the problems mentioned in the background art. Utility Model Content

[0004] To achieve the above objectives, this utility model provides a standing bed for rehabilitation training, including a bed frame and straps, and also includes a crossbar assembly, which is disposed on both sides of the bed frame and located above the straps. The crossbar assembly includes a crossbar and a height adjustment structure connected to the crossbar. A foot pedal is also fixedly installed at one end of the bed bottom.

[0005] The upper limb training component includes an extension rod and an arc rod.

[0009] As a further improvement of this utility model, the adjusting component includes a sleeve fitted onto the extension rod, the sleeve being fixedly connected to the arc-shaped rod, and the limiting component includes a stop bar provided on the sleeve. The extension rod is provided with a positioning part that cooperates with the stop bar. The sleeve fitting design allows the arc-shaped rod to be adjusted at multiple angles, optimizes mechanical transmission, and avoids stress concentration.

[0010] As a further improvement of this utility model, the positioning part includes multiple positioning holes and positioning pins that can be inserted into the positioning holes. The positioning holes are evenly distributed around the outer periphery of the connection end between the extension rod and the arc-shaped rod. The even distribution of the positioning holes enables precise quantitative adjustment of the angle, and the positioning pins can be quickly locked when inserted.

[0011] As a further improvement of this utility model, the sleeve is provided with an auxiliary limiting member symmetrically arranged with the stop bar, and a limiting pin can be detachably installed on the extension rod near the auxiliary limiting member. The auxiliary limiting member and the limiting pin cooperate to form a two-way protection to prevent the arc rod from rotating excessively.

[0012] As a further improvement of this utility model, the auxiliary limiting component includes a limiting rod, which is set on the outer wall of the sleeve on the opposite side of the stop rod. The limiting pin is threadedly connected to the positioning hole on the extension rod and is set close to the limiting rod. The limiting pin is threadedly connected to the positioning hole, which makes it easy to remove the sandbag from the positioning hole for position adjustment according to the position of the sandbag.

[0013] As a further improvement of this utility model, the training component includes a pull ring and a counterweight sandbag. The pull ring and the counterweight sandbag are detachably connected to the end of the arc-shaped rod through a quick-release structure, which enables rapid switching between the pull ring and the sandbag. The quick-release structure includes a sliding locking ring and multiple limiting steel balls. A male connector is fixedly installed at the top of the pull ring or the counterweight sandbag. Both ends of the arc-shaped rod are provided with female connectors that mate with the male connector. Multiple through holes are evenly distributed along the circumference of the outer wall of the male connector. Each through hole is movably installed with a limiting steel ball. The sliding locking ring is slidably installed on the outer wall of the male connector through a limiting spring. An annular groove is provided on the opposite side of the sliding locking ring and the female connector. The annular groove is connected to the through hole. The pull ring or the counterweight sandbag is quickly disassembled and assembled with the arc-shaped rod through the male and female connectors.

[0014] As a further improvement of this utility model, a fixed seat is provided at the bottom of the bed, and the extension rod is inserted into the fixed seat and slidably connected thereto. A locking knob is threadedly connected to one side of the fixed seat, and the extension rod is inserted into the fixed seat and slidably connected thereto. The locking knob controls the extension and retraction to adapt to different training distance requirements.

[0015] As a further improvement of this utility model, the bed body is also connected to a bed frame, and a linear actuator and a shock absorber are provided between the bed frame and the bed body. The two ends of the linear actuator and the shock absorber are respectively hinged to the back of the bed body and the bed frame, and the tilt angle of the bed body can be adjusted by the linear actuator.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model is equipped with a height-adjustable crossbar. Through the sliding cooperation of the slider and the slide rail and the setting of fastening components, the height of the crossbar can be flexibly adjusted according to the patient's height, so that patients of different heights can easily hold the crossbar to maintain balance when standing training, reducing the difficulty of training and improving the patient's training experience and safety.

[0018] 2. This utility model is equipped with an upper limb training component, with interchangeable training parts at both ends of the arc-shaped rod and a quick-release structure design, which allows patients to choose different training methods according to their own rehabilitation needs. For example, pull ring training can enhance arm pulling force, and weighted sandbag training can improve arm strength and endurance, which greatly enriches the content of upper limb rehabilitation training and improves the rehabilitation training effect.

[0019] 3. This utility model is equipped with an angle adjustment and limiting structure.

[0029] To facilitate understanding of this utility model, a more comprehensive description of it will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of this utility model more thorough and comprehensive.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Example 1:

[0033] Please see Figure 1 , Figure 2 , Figure 5 This utility model provides a standing bed for rehabilitation training, including a bed body 1 and a strap 13, and also includes a crossbar assembly 2, which is set on both sides of the bed body 1 and located above the strap 13. The crossbar assembly 2 includes a crossbar 21 and a height adjustment structure connected to the crossbar 21. A foot pedal 11 is also fixedly installed at one end of the bed bottom.

[0034] The height adjustment structure includes a slider 22 and a slide rail 23. The slider 22 is connected to the crossbar 21. The slide rail 23 is located on both sides of the bed 1 and above the strap 13. The slider 22 and the slide rail 23 are slidably engaged. The slider 22 is provided with a fastening component for fixing the height of the crossbar 21. The slider 22 and the slide rail 23 work together to achieve continuous adjustment of the height of the crossbar 21. The rigid connection ensures structural stability and can withstand large lateral tension.

[0035] The fastening components include a locking bolt 221 and a threaded hole that mates with the locking bolt 221. The threaded hole is located on the side of the slider 22. The bolt with a knob is screwed in. A rubber gasket can be provided at the end of the locking bolt 221 that contacts the slide rail 23. The knob-type locking bolt 221 allows for quick adjustment with one hand. The rubber gasket increases friction and prevents the crossbar 21 from slipping during use.

[0036] The bed body 1 is also connected to the bed frame 14. A linear actuator 12 and a shock absorber 5 are provided between the bed frame 14 and the bed body 1. The two ends of the linear actuator 12 and the shock absorber 5 are respectively hinged to the back of the bed body 1 and the bed frame 14. The tilt angle of the bed body 1 can be adjusted by the linear actuator 12.

[0037] In use, the angle of the bed 1 is adjusted by the linear actuator 12 until a suitable angle is reached. The shock absorber 5 effectively reduces the vibration caused by the rotation of the bed 1. The user stands on the foot pedal 11, and then, according to the user's height, loosens the locking bolt 221 in the fastening component on the slider 22 of the crossbar assembly 2, slides the crossbar 21 down along the slide rail 23, and adjusts it to a height that is convenient for the user to hold the crossbar 21 when their hands hang naturally. Then, the locking bolt 221 is tightened to fix the crossbar 21. The user stands on the bed 1, holds the crossbar 21 with both hands, and maintains body balance by relying on the support of the crossbar 21 to perform standing training. By holding the crossbar 21, the user can stabilize their body posture, reduce the risk of falling when standing, gradually adapt to the standing posture, and exercise the lower limb muscle strength and body balance ability. In this embodiment, the height adjustment function of the crossbar assembly 2 allows patients of different heights to obtain suitable support, effectively assisting patients in standing balance training. At the same time, the straps 13 set on the bed 1, in conjunction with the crossbar 21, can further protect the patient.

[0038] Example 2:

[0039] Based on Example 1, please refer to Figure 3-8 The upper limb training component 3 includes an extension rod 31 and an arc rod 32. The extension rod 31 is telescopically installed at the bottom of the bed 1, with one end extending away from the bed 1 and having a foot pedal 11. The arc rod 32 is rotatably connected to the extension rod 31, and training components 33 are connected to both ends of the arc rod 32, and the positions of the two training components 33 can be interchanged.

[0040] Training component 33 includes a pull ring 331 and a counterweight sandbag 332. The pull ring 331 and the counterweight sandbag 332 are detachably connected to the end of the arc-shaped rod 32 through a quick-release structure 34. The quick-release structure 34 enables quick switching between the pull ring 331 and the sandbag.

[0041] The quick-release structure 34 includes a sliding locking ring 343 and multiple limiting steel balls 344. A male connector 341 is fixedly installed at the top of the pull ring 331 or the counterweight sandbag 332. The two ends of the arc-shaped rod 32 are provided with female connectors 342 that mate with the male connector 341. Multiple through holes are evenly distributed along the circumference of the outer wall of the male connector 341. Each through hole is movably installed with a limiting steel ball 344. The sliding locking ring 343 is slidably installed on the outer wall of the male connector 341 through a limiting spring 345. The sliding locking ring 343 and the female connector 342 are provided with an annular groove 346 on opposite sides. The annular groove 346 is connected to the through hole. The pull ring 331 or the counterweight sandbag 332 and the arc-shaped rod 32 can be quickly disassembled and assembled through the male connector 341 and the female connector 342.

[0042] The bottom of the bed 1 is provided with a fixed seat 311. The extension rod 31 is inserted into the fixed seat 311 and slidably connected thereto. A locking knob 312 is threadedly connected to one side of the fixed seat 311. The extension rod 31 is inserted into the fixed seat 311 and slidably connected. The locking knob 312 controls the extension and retraction to adapt to different training distance requirements.

[0043] When upper limb strength training is required, according to the training plan, pull ring 331 and counterweight sandbag 332 are selected as training components 33. The pull ring 331 and counterweight sandbag 332 are respectively installed at both ends of the arc-shaped rod 32 via quick-release structure 34. The sliding locking ring 343 is pulled to slide axially along the male connector 341 and compress the limiting spring 345, causing the annular groove 346 inside the sliding locking ring 343 to intersect with the through hole of the male connector 341. The female connector 342 on the arc-shaped rod 32 is inserted into the male connector 341 at the top of the pull ring 331 or sandbag. When the annular groove 346 on the outer wall of the female connector 342 completely overlaps with the through hole of the male connector 341, the limiting steel ball 344 is engaged in the annular groove 346. Then, the sliding locking ring 343 is released, and under the rebound force of the limiting spring 345, the annular groove 346 on the sliding locking ring 343 is pushed to align with the through hole, thus controlling the limiting steel ball 344. The device limits and forms a secondary lock. When performing upper limb strength training, the user stands on the foot pedal 11 of the bed 1, holds the pull ring 331 with one hand, and stretches the arm. After training one arm, the user pulls the sliding locking ring 343 again, causing the annular groove 346 to disengage from the steel ball. The steel ball contacts the restriction, and the male connector 341 is pulled out axially to complete the quick disassembly. The positions of the pull ring 331 and the sandbag are then interchanged to train the other arm. In this embodiment, the quick-release structure 34 allows the pull ring 331 and the sandbag to be replaced. The telescopic design of the extension rod 31 allows the training radius to be adjusted within the range of 0.8-1.5m to accommodate users of different body types. With the weight gradient of the sandbag (1kg, 2kg, 5kg), medical staff can develop personalized training plans (such as using a 2kg sandbag in the first week and changing to a 5kg sandbag in the second week) to achieve a step-by-step improvement in muscle strength.

[0044] Example 3:

[0045] Based on Example 2, please refer to Figure 3-5 An angle adjustment and limiting structure 4 is also provided at the connection between the arc rod 32 and the extension rod 31. The angle adjustment and limiting structure 4 includes an adjusting component for adjusting the angle of the arc rod 32 and a limiting component for limiting the rotation range of the arc rod 32. It integrates standing balance and upper limb training functions, is suitable for patients of different heights and rehabilitation stages, and improves training safety through angle limiting.

[0046] The adjusting component includes a sleeve 41 fitted onto the extension rod 31, the sleeve 41 being fixedly connected to the arc-shaped rod 32, and the limiting component includes a stop bar 42 provided on the sleeve 41. The extension rod 31 is provided with a positioning part that cooperates with the stop bar 42. The sleeve 41 fitting design allows the arc-shaped rod 32 to be adjusted at multiple angles, optimizes mechanical transmission, and avoids stress concentration.

[0047] The positioning part includes multiple positioning holes 43 and positioning pins 431 that can be inserted into the positioning holes 43. The positioning holes 43 are evenly distributed around the outer periphery of the connection end between the extension rod 31 and the arc rod 32. The even distribution of the positioning holes 43 enables precise quantitative adjustment of the angle, and the positioning pins 431 can be quickly locked when inserted.

[0048] The sleeve 41 is provided with an auxiliary limiting component symmetrically arranged with the stop bar 42. A limiting pin 44 can be detachably installed on the extension bar 31 near the auxiliary limiting component. The auxiliary limiting component and the limiting pin 44 cooperate to form a two-way protection to prevent the arc-shaped bar 32 from rotating excessively.

[0049] The auxiliary limiting component includes a limiting rod 45, which is set on the outer wall of the sleeve 41 on the opposite side of the stop rod 42. The limiting pin 44 is threadedly connected to the positioning hole 43 on the extension rod 31 and is set close to the limiting rod 45. The limiting pin 44 is threadedly connected to the positioning hole 43, which makes it easy to remove it from the positioning hole 43 for position adjustment according to the position of the sandbag.

[0050] Before training, the angle can be limited along the positioning hole 43 on the outside of the extension rod 31 according to the needs of different users. Simply insert the positioning pin 431 into the positioning hole 43 at the corresponding angle on one side of the pull ring 331. When the pull ring 331 is pulled, the stop bar 42 on its sleeve 41 cooperates with the positioning pin 431 to limit the movement. This not only prevents the user from pulling the pull ring 331 too much when doing upper limb training, but also limits the training, improving the flexibility and safety of the equipment. Furthermore, in order to prevent the sandbag from causing the pull ring 331 to rotate excessively under the action of gravity, a limit pin 44 is also provided on the extension rod 31. The position of the limit pin 44 is set close to the sleeve when the arc rod 32 is in a horizontal state. On one side of the lower limiting rod 45, the limiting pin 44 is connected to the positioning hole 43 by a thread. The limiting pin 44 is installed in the positioning hole 43 near the pull ring 331. When the positions of the sandbag and the pull ring 331 are interchanged, the positions of the limiting pin 44 and the positioning pin 431 must also be interchanged. The stop bar 42 on the sleeve 41 forms a bidirectional limit with the limiting pin 44. During the training process, due to the action of the angle adjustment limiting structure 4, the arc rod 32 is kept in the set position and will not rotate excessively due to the force applied by the patient, ensuring the safety and accuracy of the training. In this embodiment, the limiting rod 45, the positioning pin 431 and the stop bar 42 are wrapped with a silent soft pad, which can reduce the noise and vibration generated when touched.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
