Description

Technical Field

[0001] This utility model relates to the field of rehabilitation training equipment technology, specifically a suspension rehabilitation training device. Background Technology

[0002] Patients with limb paralysis lose the ability to move their limbs independently, which affects the healthy circulation of blood and the flexibility of joints. This can easily lead to the degeneration and deformation of the morphology and structure of the motor organs. Over time, it can also cause the gradual decline of visceral function and is very detrimental to the recovery of the nervous system and the improvement of muscle strength. Therefore, postoperative exercise training has become the main means of rehabilitation for patients.

[0003] Because manually assisting patients with rehabilitation training is extremely labor-intensive, suspension rehabilitation training devices are often used to assist patients in limb rehabilitation training. This is not only highly efficient but also significantly reduces the workload of medical staff. Suspension rehabilitation training devices are core rehabilitation equipment that assists medical staff in suspension rehabilitation therapy. They play an important role in treating limb disorders, nerve injuries, and joint inflammation, effectively helping patients with limited limb joint movement and weakened limb strength to perform motor rehabilitation and improve their core stability.

[0004] The suspension rehabilitation training device mainly consists of a main frame and several suspension mechanisms. Each suspension mechanism is equipped with wear-resistant and non-slip suspension ropes to support the patient's limbs. The length of the suspension ropes needs to be manually adjusted by medical staff to accommodate different patient body shapes or training of different body parts. Each suspension mechanism can slide freely along the length of the main frame independently and is equipped with a locking mechanism to allow for switching training of different body parts. In actual use, medical staff need to constantly switch training areas and adjust training methods, requiring repeated manual adjustments to the position of the suspension mechanisms and the length of the suspension ropes. This significantly increases the workload for medical staff and prolongs the rehabilitation treatment period. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a suspension rehabilitation training device that allows for convenient adjustment of the position of the suspension mechanism.

[0006] The technical solution of this utility model is to provide a suspension rehabilitation training device with the following structure: including a main frame and at least one suspension mechanism connected to the main frame; the main frame includes a support beam and a crossbeam connected to the support beam, the crossbeam is provided with a rack guide rail extending along its length direction, and the support beam is provided with a linear guide rail parallel to the rack guide rail; the suspension mechanism includes a housing and a first drive unit and a pull rope assembly disposed on the housing, the housing is slidably connected to the linear guide rail, and the first drive unit meshes with the rack guide rail for driving the suspension mechanism to slide along the linear guide rail.

[0007] With the above structure, the suspension rehabilitation training device of this utility model has the following advantages compared with the prior art:

[0008] This invention features a rack and pinion guide rail on a crossbeam and a first drive unit within the housing. The suspension mechanism slides along the linear guide rail via the meshing transmission between the first drive unit and the rack and pinion guide rail, eliminating the need for manual adjustment of the suspension mechanism's position, reducing the operational difficulty for medical personnel, and increasing the efficiency of rehabilitation training. Furthermore, after the suspension mechanism is adjusted to its position, the gears of the first drive unit and the rack and pinion guide rail also have a locking function, eliminating the need for a locking structure to fix the position of the suspension mechanism.

[0009] Preferably, there are two linear guides, symmetrically arranged at both ends of the rack guide; the two ends of the housing are provided with linear bearings corresponding to the two linear guides, and the linear guides pass through the corresponding linear bearings and slide in contact with the linear bearings. The sliding contact between the two linear guides and the two linear bearings ensures the stability of the suspension mechanism during movement.

[0010] Preferably, a first anti-collision block made of elastic material is provided on the support beam below the crossbeam. The first anti-collision block is used to abut against the outer wall of the shell, providing a cushioning effect. When the shell moves, it cannot stop immediately due to inertia. The elastic first anti-collision block can prevent the shell from directly hitting the support beam, thus avoiding damage to the equipment.

[0011] A distance sensor and a second anti-collision block are provided on the outer wall of the housing facing the first anti-collision block. A control unit is provided inside the housing, and the control unit is electrically connected to the distance sensor and the first drive unit respectively. The distance sensor is used to detect the distance between the suspension mechanism and the first anti-collision block, and can also detect the distance between two adjacent suspension mechanisms, and sends a signal to the control unit. The control unit will promptly control the first drive unit to stop operating to avoid a collision, while the second anti-collision block can act as a buffer in the event of a collision.

[0012] Preferably, a motor bracket is connected inside the housing, and the first drive unit and the linear bearing are fixedly connected to the motor bracket. A weighing sensor is also provided inside the housing, with its two ends connected to the motor bracket and the pull rope assembly, respectively, for detecting the tension on the pull rope assembly. The weighing sensor is used to accurately detect the tension on the pull rope assembly, feeding back the shaking of the patient's training area to the control unit, thereby helping medical staff better assess the patient's core stability.

[0013] Preferably, the rope assembly includes a mounting base plate, a second drive unit, a rope wheel, and a suspension rope; the top of the mounting base plate is connected to a weighing sensor, the second drive unit and the rope wheel are fixedly connected to the mounting base plate, the second drive unit is driven by the rope wheel to drive the rope wheel to rotate; the mounting base plate has a rope hole extending downward and penetrating the housing, one end of the suspension rope is connected to the outer peripheral wall of the rope wheel, and the other end passes through the rope hole and extends to the outside of the housing.

[0015] Preferably, the housing includes a wireless transmission module for wireless connection with an external remote control. This wireless connection allows the user to easily control the horizontal movement of the suspension mechanism and the vertical movement of the suspension rope. Attached Figure Description

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown;

[0027] This utility model discloses a suspension rehabilitation training device, which includes a main frame 1 and three suspension mechanisms 2 connected to the main frame 1.

[0028] The main frame 1 includes a support beam 11 and a crossbeam 12 connected to the support beam 11. The crossbeam 12 is provided with a rack guide rail 13 extending along its length, and the support beam 11 is provided with a linear guide rail 14 parallel to the rack guide rail 13. The support beam 11 is also provided with a connecting column 15, which can be installed upwards on the roof load-bearing beam or downwards on the ground frame, allowing for flexible installation.

[0029] The suspension mechanism 2 includes a housing 21 and a first drive unit 22 and a rope assembly 23 disposed on the housing 21. The housing 21 is slidably connected to the linear guide rail 14. The output end of the first drive unit 22 is connected to a gear, which meshes with the rack and pinion guide rail 13 to drive the suspension mechanism 2 to slide along the linear guide rail 14.

[0030] This invention features a rack and pinion guide rail 13 on the crossbeam 12 and a first drive unit 22 inside the housing 21. The suspension mechanism 2 is driven to slide along the linear guide rail 14 by the meshing transmission between the first drive unit 22 and the rack and pinion guide rail 13. This eliminates the need for manual adjustment of the position of the suspension mechanism 2, reducing the operational difficulty for medical staff and increasing the efficiency of rehabilitation training. Furthermore, after the suspension mechanism 2 is adjusted to the correct position, the gear of the first drive unit 22 and the rack and pinion guide rail 13 also have a locking function, eliminating the need to fix the position of the suspension mechanism 2 using a locking structure.

[0031] Two linear guide rails 14 can be provided and symmetrically arranged at both ends of the rack guide rail 13; the two ends of the housing 21 are provided with linear bearings 211 corresponding to the two linear guide rails 14. The linear guide rails 14 pass through the corresponding linear bearings 211 and slide with the linear bearings 211 to ensure the stability of the suspension mechanism 2 when it moves.

[0032] A first anti-collision block 111 made of elastic material is provided on the support beam 11 below the crossbeam 12. The first anti-collision block 111 is used to abut against the outer wall of the housing 21 to play a buffering role. When the housing 21 moves, it cannot stop immediately due to inertia. The elastic first anti-collision block 111 can prevent the housing 21 from directly hitting the support beam 11 and avoid damage to the equipment.

[0033] A distance sensor 212 and a second anti-collision block 214 are provided on the outer side wall of the housing 21 facing the first anti-collision block 111. A control unit (not shown in the figure) is provided inside the housing 21. The control unit is electrically connected to the distance sensor 212 and the first drive unit 22 respectively.

[0034] The distance sensor 212 is used to detect the distance between the suspension mechanism 2 and the first anti-collision block 111, and can also detect the distance between two adjacent suspension mechanisms 2. It sends a signal to the control unit, which will promptly control the first drive unit 22 to stop operating to avoid a collision. The second anti-collision block 214 can act as a buffer in the event of a collision.

[0035] A motor bracket 213 is connected inside the housing 21, and the first drive unit 22 and linear bearing 211 are fixedly connected to the motor bracket 213. A weighing sensor 24 is also provided inside the housing 21. The two ends of the weighing sensor 24 are connected to the motor bracket 213 and the pull rope assembly 23, respectively, to accurately detect the tension on the pull rope assembly 23 and to feed back the shaking of the patient's training area to the control unit, thereby helping medical staff to better judge the patient's core stability.

[0036] The rope assembly 23 includes a mounting base plate 231, a second drive unit 232, two rope pulleys 233, and two suspension ropes 234. The top of the mounting base plate 231 is connected to the weighing sensor 24. The second drive unit 232 is fixedly connected to the mounting base plate 231. The two rope pulleys 233 are respectively located at both ends of the mounting base plate 231 and are connected by a belt. The second drive unit 232 is driven by one of the rope pulleys 233 to drive the two rope pulleys 233 to rotate synchronously. The mounting base plate 231 has two rope holes 2311 that extend downward and penetrate the housing 21. One end of the suspension rope 234 is connected to the outer peripheral wall of the corresponding rope pulley 233, and the other end passes through the corresponding rope hole 2311 and extends to the outside of the housing 21.

[0037] The belt is also equipped with a limit block 235, and the mounting base plate 231 is also equipped with a limit stop plate 236, which are used to limit the limit block 235, thereby limiting the lifting height of the suspension rope 234. A potentiometer is also installed at the rear end of the shaft on the other side of the second drive unit 232 to record the number of rotations of the rope wheel 233, thus achieving precise reading and memorization of the length of the suspension rope 234. When changing patients, the length of the suspension rope 234 can be adjusted with a single button based on the memorized position, saving patients' preparation time for rehabilitation training. The second drive unit 232 has a built-in brake. After adjusting the height of the suspension rope 234, the second drive unit 232 stops working and the brake engages, ensuring the stability and reliability of the suspension rope 234 height during training and preventing unnecessary harm to the patient.

[0038] The housing 21 also houses a wireless transmission module, which is electrically connected to the control unit. This module allows for wireless connection with an external remote control to transmit control commands, facilitating user control of the horizontal movement of the suspension mechanism 2 and the vertical movement of the suspension rope 234. The control unit is a controller, and the first drive unit 22 and the second drive unit 232 can be stepper motors. The controller is electrically connected to the load cell 24 and the two stepper motors.

[0039] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
