Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a limb function training device for neurology. Background Art

[0002] Patients with neurological diseases often suffer from decreased limb mobility due to central or peripheral nerve damage, and in severe cases even limb paralysis or motor dysfunction. For such patients, limb rehabilitation training is an important part of neurological rehabilitation treatment. Its main purpose is to promote nerve remodeling, increase muscle strength, and improve joint mobility, thereby restoring the patient's basic motor function and improving their ability to take care of themselves. However, since nerve damage is usually accompanied by problems such as abnormal muscle tone and decreased coordination, the rehabilitation training process is often more complicated and requires scientific and reasonable training plans and appropriate rehabilitation equipment to assist.

[0003] At present, neurological rehabilitation training usually relies on manual training by physical therapists or the use of special limb function training devices. For example, Chinese patent announcement number CN114949741A discloses a limb function training device for neurological nursing. The device adopts a fixed seat combined with a movable backrest, so that patients can perform simple training through back support. At the same time, it also provides an arm pressing support plate and a foot pedal structure to assist patients in upper and lower limb exercises. This type of device provides certain training assistance through a mechanical structure, which can help patients perform limb activities to a certain extent, reduce the dependence of rehabilitation training on medical staff, and improve the autonomy of training.

[0004] Although the above-mentioned limb function training devices have met the needs of neurological rehabilitation training to a certain extent, there are still many limitations. For example, some devices rely on mechanical adjustment and lack intelligent control, which makes the training method relatively fixed and difficult to flexibly adjust according to the patient's muscle strength. In addition, the training content of the device is relatively single. For example, arm training only supports simple up and down pressing, and foot training only provides basic stepping movements, which cannot meet the patient's multi-angle and different intensity rehabilitation needs. At the same time, for patients who need passive assisted training, the movement pattern of the existing device is relatively rigid, which may lead to insufficient comfort during training and affect the rehabilitation effect.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Please refer to the attached Figure 1The embodiment of the present invention provides a limb function training device for neurology, including two base frames 1, a movable seat 2 is slidably provided on opposite sides of the two base frames 1, a chair frame 4 is fixed on opposite sides of the two base frames 1, the bottom of the movable seat 2 and the chair frame 4 are connected by a first adjustment component, which is used to control the distance between the movable seat 2 and the chair frame 4, so that the patient's legs can be bent and stretched, mounting plates 7 are fixed on both sides of the top of the movable seat 2, a rotating rod 1 8 and a rotating rod 2 12 are fixed between the two mounting plates 7, and footrests are rotatably provided on both sides of the outer wall of the rotating rod 1 8 Board 9, the outer walls of the two footboards 9 are fixed with footboards 10, and the outer side of each footboard 10 is fixed with a fixing belt 11, which is used to fix the patient's feet. The rotating rod 12 and the footboard 9 are connected by a second adjusting component, which is used to drive the patient's feet to move. The top of the two base frames 1 is fixed with a mounting frame 19, and the top of the mounting frame 19 is provided with a driving component, which is used to adjust the pay-off length of the connecting rope 24. The patient's hands are stretched by the pull rod 25 in cooperation with the third adjusting component. A seat 33 is provided on the top of the chair frame 4.

[0025] Please refer to the attached Figure 3 The first adjustment component includes two connecting seats 3, the tops of the two connecting seats 3 are respectively fixed on the tops of the moving seats 2, mounting seats 5 are fixed on both sides of the outer wall of the chair frame 4, and electric telescopic rods 6 are rotated in the middle of the two mounting seats 5, and the other ends of the two electric telescopic rods 6 are respectively rotated in the middle of the two connecting seats 3.

[0026] Specifically, when exercising the patient's legs, the electric telescopic rod 6 can be started to make the movable seat 2 slide inside the two base frames 1, thereby driving the patient's legs to bend and stretch.

[0027] Please refer to the attached Figure 4 The second adjustment component includes two adjustment seats 13, the middle parts of the two adjustment seats 13 rotate outside the rotating rod 12, and the middle parts of the two adjustment seats 13 are installed with buffer tubes 14. A moving rod 15 slides in the middle part of each buffer tube 14, and a spring 16 is sleeved on the outside of the moving rod 15. A movable block 38 rotates at the end of the moving rod 15, and the movable block 38 is installed outside the middle part of the foot plate 9. An electric telescopic rod 17 rotates in the middle part of the adjustment seat 13, and a movable block 18 rotates at the driving end of the electric telescopic rod 17, and the movable block 18 is installed outside the middle part of the foot plate 9.

[0028] Specifically, when it is necessary to exercise the patient's foot, the electric telescopic rod 17 can be started to reduce or increase the angle between the foot plate 9 and the movable seat 2, so that the patient's ankle can be exercised in a targeted manner. When the electric telescopic rod 17 is started, when the foot plate 9 rotates outside the rotating rod 8, its movable rod 15 will slide inside the buffer tube 14, thereby compressing the spring 16 to generate a rebound reaction force to assist the foot plate 9 in resetting. Through this adjustment, the patient's foot muscles and ankle joints can be exercised in a targeted manner. Compared with traditional mechanical stretching equipment, the present invention not only provides more precise foot activity control, but also can effectively avoid a rigid single movement mode, thereby improving the patient's ankle flexibility, enhancing the effect of walking recovery, and improving the overall comfort of exercise.

[0029] Please refer to the attached Figure 2 The driving component includes a bidirectional motor 21, the bottom of which is fixed to the top of the mounting frame 19, and fixed seats 20 are fixed on both sides of the top of the mounting frame 19. The output ends on both sides of the bidirectional motor 21 are connected to a rotating wheel 23 through a rotating shaft 22, and each rotating wheel 23 is arranged outside the middle of the fixed seat 20.

[0030] One end of a connecting rope 24 is connected to the outside of the rotating wheel 1 23 , and the other end of the connecting rope 24 is connected to a pull rod 25 through a connecting piece 26 .

[0031] Two fixing seats 27 are installed on both sides of the outer wall of the cross beam of the mounting frame 19, and pulleys 28 are rotated in the middle of the two fixing seats 27, and the outside of the connecting rope 24 is closely attached to the outer wall of the pulley 28.

[0032] Specifically, when the patient needs to perform strength stretching exercises, the flexible robot gloves 37 can be directly controlled to make the patient's hands clenched on the outside of the pull rod 25, and then the two-way motor 21 is started to control the wheels 23 on both sides to rotate synchronously, so that the length of the connecting rope 24 is controlled. When the pay-off length of the connecting rope 24 is shortened, the pull rod 25 is close to the fixed seat 2 27. At this time, the hydraulic cylinder 1 32 and the hydraulic cylinder 2 36 are used to stretch the patient's arms, and the control of the first adjustment component is used at this time. When the patient's legs are bent, the patient can tend to stand in a stretched position, so that the patient's buttocks slightly leave the seat 33. At this time, under the action of the body's gravity, the muscles of the limbs are stretched, activating the muscles of the limbs to help with muscle movement and stretching.

[0033] During the stretching process, the connecting rope 24 passes through the pulley 28 to prevent the connecting rope 24 from contacting the outer wall of the mounting frame 19 and being worn.

[0034] Please refer to the attached Figure 5Slides 29 are installed on both sides of the top of the chair frame 4, and limiting grooves 30 are opened on the tops of the two slides 29. One end of a movable rod 34 is rotated on both sides of the outer wall of the seat 33, and the other end of the movable rod 34 is rotated with one end of a movable rod 2 35. The outer wall of the other end of the movable rod 34 is rotated with one end of a hydraulic cylinder 1 32, and the other end of the hydraulic cylinder 1 32 is rotated with a limit block 31, and the bottom of the limit block 31 slides in the limiting groove 30, and the outer wall of the movable rod 1 34 is rotated with one end of a hydraulic cylinder 2 36, and the other end of the hydraulic cylinder 2 36 is rotated on the other end of the movable rod 2 35, and the outer wall of the movable rod 2 35 is connected with a flexible robot glove 37.

[0035] Specifically, when exercising the patient's arm, the hydraulic cylinder 1 32 and the hydraulic cylinder 2 36 can be started to drive the movable rod 1 34 and the movable rod 2 35 to fold, thereby driving the flexible robot glove 37 to move in position, such as driving the patient's arm to move up and down, forward and backward, and other positions, so that the patient's arm can be exercised. At the same time, when exercising the patient's hand, the flexible robot glove 37 can be controlled to exercise the patient's hand.

[0036] Working principle: When using the device of the present invention to perform limb exercises on patients, the patient must first sit on the seat 33, wear the flexible robot gloves 37 on the patient's hands, and place the patient's feet on the sole plate 10, and use the fixing belt 11 to fix the patient's feet on the sole plate 10. After the preparation work is completed, the patient's limbs can be exercised.

[0037] When exercising the patient's legs, the electric telescopic rod 1 6 can be started to make the movable seat 2 slide inside the two base frames 1, thereby driving the patient's legs to bend and stretch. When the patient's feet need to be exercised, the electric telescopic rod 2 17 can be started to reduce or increase the angle between the foot plate 9 and the movable seat 2, so that the patient's ankles can be exercised in a targeted manner. When the electric telescopic rod 2 17 is started, when the foot plate 9 rotates outside the rotating rod 1 8, its movable rod 15 will slide inside the buffer tube 14, thereby compressing the spring 16, causing it to generate a rebound reaction force to assist the foot plate 9 in resetting.

[0038] When exercising the patient's arm, the movable rod 1 34 and the movable rod 2 35 can be driven to fold by starting the hydraulic cylinder 1 32 and the hydraulic cylinder 2 36, thereby driving the flexible robot glove 37 to move, such as driving the patient's arm to move up and down, forward and backward, and other positions, so that the patient's arm can be exercised. At the same time, when exercising the patient's hand, the flexible robot glove 37 can be controlled to exercise the patient's hand. At the same time, when the patient needs to perform strength stretching exercises, the patient's hand can be directly controlled by the flexible robot glove 37 to clench the outside of the pull rod 25. The bidirectional motor 21 is then started to control the wheels 23 on both sides to rotate synchronously, so that the length of the connecting rope 24 is controlled. When the pay-off length of the connecting rope 24 is shortened, the pull rod 25 is close to the fixed seat 27. At this time, the hydraulic cylinder 1 32 and the hydraulic cylinder 2 36 are used to stretch the patient's arms. In combination with the control of the first adjustment component at this time, when the patient's legs are bent, the patient can tend to stand in a stretched position, so that the patient's buttocks slightly leave the seat 33. At this time, under the action of the body's gravity, the muscles of the limbs are stretched, activating the muscles of the limbs and helping with muscle movement and stretching.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
