Description

Technical Field

[0001] This utility model relates to the field of medical rehabilitation equipment technology, and in particular to a walking training device for hemiplegic patients. Background Technology

[0002] An assisted walking trainer is a rehabilitation device used to assist hemiplegic patients with walking training. It serves as an indoor and outdoor mobility aid for patients with neurological and musculoskeletal disorders. Designed based on biomechanical principles, it enhances assisted walking by increasing the area of ​​upper limb support. It helps patients practice correct gait patterns and postures, thereby improving their walking function and quality of life.

[0003] However, existing walking rehabilitation training devices are generally walking belts that exercise both feet simultaneously when activated. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a walking training device for hemiplegic patients, which solves the problem that both feet do not need to be trained at the same time.

[0005] To solve the above-mentioned technical problems, this utility model provides a walking training device for hemiplegic patients, including a base, handrails on both sides of the base, two foot pedals on the base, an independent linear motion mechanism between the foot pedals and the base, a crossbar in front of the handrails, a first button on the crossbar to control the linear motion mechanism to move forward, and a second button on the handrails to control the linear motion mechanism to move backward. When the first button is activated, the linear motion mechanism drives the foot pedals to move forward; when the second button is activated, the linear motion mechanism drives the foot pedals to move backward, thereby causing the foot placed on the foot pedals to move back and forth.

[0006] In a preferred embodiment, the linear motion mechanism includes a mounting plate for mounting a foot pedal, a rail mounted on a base, a guide device between the mounting plate and the rail, and a power mechanism between the mounting plate and the base.

[0007] In a preferred embodiment, a height adjustment device is provided between the crossbar and the handrail. The height adjustment is used to adjust the height of the first button, thereby accommodating patients of different heights.

[0008] In a preferred embodiment, the height adjustment device is a rodless cylinder, which includes a second slider and a crossbar mounted on the second slider.

[0009] In a preferred embodiment, the power mechanism includes a permanent magnet located below the base and electromagnets located on both sides of the track. The electromagnets are energized by a start button, thereby attracting the permanent magnet and causing one foot to move to one side.

[0010] In a preferred embodiment, the power mechanism includes a first slider mounted on a permanent magnet, a ball screw mounted on the first slider, a motor mounted on one side of the ball screw, and a motor mounting base. When the motor is started, it drives the foot pedal to move to one side.

[0011] In the preferred embodiment, a mounting groove is provided on the base, and the linear motion mechanism is installed in the mounting groove.

[0012] The beneficial effect of this utility model is that by setting two separate foot pedals and a linear motion mechanism under the foot pedals, and then setting a first button and a second button for separate control, the foot pedal on one side can be controlled to move back and forth by the corresponding first button and second button, thereby driving one foot to perform rehabilitation exercises back and forth, while the other foot remains still, preventing the patient from developing too many abnormal movement patterns.

Detailed Implementation

[0023] Example 1

[0024] Please see Figure 1-8 As shown in the embodiments of this application, a technical solution is provided: a walking training device for hemiplegic patients.

[0025] In a preferred embodiment, the system includes a base 11, handrails 12 on both sides of the base 11, two foot pedals 13 on the base 11, an independent linear motion mechanism 2 between the foot pedals 13 and the base 11, a crossbar 16 in front of the handrails 12, a first button 14 on the crossbar 16 to control the linear motion mechanism 2 to move forward, and a second button 15 on the handrails 12 to control the linear motion mechanism 2 to move backward. When the first button 14 is activated, the linear motion mechanism 2 drives the foot pedals 13 to move forward; when the second button 15 is activated, the linear motion mechanism 2 drives the foot pedals 13 to move backward, thereby causing the feet placed on the foot pedals 13 to move back and forth.

[0026] One first button 14 is provided for alternating control, such as a knob. Two second buttons 15 are provided, corresponding one-to-one with the linear motion mechanism 2 below the foot pedal 13. This allows for individual control of one side of the foot pedal 13 via the corresponding first button 14 and second button 15, enabling one foot to perform rehabilitation exercises while the other foot remains stationary, preventing excessive abnormal movement patterns. When it's necessary to move the other foot, the control button on this side remains stationary.

[0027] The first button 14 and the second button 15 can be pressed briefly. Pressing the button once will move the linear motion mechanism 2 a certain distance and then stop it. If the button is not pressed, the linear motion mechanism 2 will remain stationary.

[0028] In a preferred embodiment, the linear motion mechanism 2 includes a mounting plate 21 for mounting the foot pedal 13, a track 22 disposed on the base 11, a guide device 23 disposed between the mounting plate 21 and the track 22, and a power mechanism 3 disposed between the mounting plate 21 and the base 11.

[0029] When the track 22 is cylindrical, the guide device 23 is a roller structure; when the track 22 is a linear guide, the guide device 23 is a corresponding slider.

[0030] In a preferred embodiment, a height adjustment device 4 is provided between the crossbar 16 and the handrail 12. The height adjustment is used to adjust the height of the first button 14, thereby accommodating patients of different heights.

[0031] In a preferred embodiment, the height adjustment device 4 is a rodless cylinder 41, which includes a second slider 411 and a crossbar 16 mounted on the second slider 411.

[0032] For rodless cylinder 41, you can choose the SMC brand, which is a well-known product.

[0033] In a preferred embodiment, the power mechanism 3 includes a permanent magnet 31 located below the base 11 and electromagnets 32 located on both sides of the track 22. The electromagnets 32 are energized by the start button, thereby attracting the permanent magnet 31 and driving one foot pedal 13 to move to one side.

[0034] During exercise, the electromagnet 32 ​​on one side is energized while the electromagnet on the other side is de-energized, and the foot pedal 13 is moved to one side by magnetic force.

[0035] Example 2

[0036] Further explanation in conjunction with Example 1;

[0037] In a preferred embodiment, the power mechanism 3 includes a first slider 33 mounted on a permanent magnet 31, a ball screw 34 mounted on the first slider 33, a motor 35 mounted on one side of the ball screw 34, and a mounting base 36 for the motor 35. When the motor 35 is started, it drives the foot pedal 13 to move to one side.

[0038] The biggest difference between this solution and the electromagnet 32 ​​solution is that it allows the foot pedal to travel a greater distance.

[0039] In a preferred embodiment, a mounting groove 111 is provided on the base 11, and the linear motion mechanism 2 is installed in the mounting groove 111.

[0040] This makes the linear motion mechanism 2 more aesthetically pleasing and less prone to interference. The height adjustment device 4 can also be installed in the same way.

[0041] A lifting device is also provided behind the handrail 12. The lifting device includes a connecting plate, which is equivalent to the crossbar 16. The whole is in the same shape as the crossbar 16 and the height adjustment device 4. By automatically raising the height of the connecting plate, the patient is prevented from falling backward and then falling to the ground.

[0042] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
