Description

[Technical Field]

[0001] The present invention relates to the technical field of rehabilitation assistive devices, and more particularly to a lower limb rehabilitation device for use by stroke patients. [Background technology]

[0002] Stroke patients often suffer from motor dysfunction in the lower limbs, and leg muscle spasms and cramps are frequent complications during the recovery phase. These not only increase patients' pain, but also hinder the progress of rehabilitation, significantly impacting the recovery of limb function. Most lower limb rehabilitation devices currently widely used in clinical practice primarily focus on passive exercise training and are insufficiently designed to specifically alleviate muscle spasms. Furthermore, their rigid fixation structures make them difficult to adapt to differences in patient physique and rehabilitation posture, and the complicated adjustment process makes them impractical. While some simple massage devices have a soothing effect, their insufficient fixation and inability to precisely control massage intensity and range make them difficult to effectively prevent seizures. Furthermore, existing devices have a single function and limited adaptability, limiting their therapeutic effectiveness and widespread adoption, as they cannot meet the diverse rehabilitation needs of patients. Therefore, the development of a lower limb rehabilitation device that has a rational structure, can accurately relieve muscle spasms, is flexibly adjustable in height and angle, and is easy to operate is highly urgent in improving the quality of rehabilitation for stroke patients, and has great clinical value and potential for future development.

A front support rod 4 and a rear support rod 5 are provided at both ends of the two bottom U-shaped plates 3, with the front support rods 4 and the rear support rods 5 also being symmetrically arranged. An upper U-shaped plate 6 is provided across the tops of the front support rod 4 and the rear support rod 5 on the same side, with the opening of the upper U-shaped plate 6 facing downward. An auxiliary U-shaped plate 7 is provided at the rear of the bottom U-shaped plate 3, and the extending direction of the auxiliary U-shaped plate 7 is the same as that of the bottom U-shaped plate 3. A lower rod 8 is provided at the end of each of the two symmetrically arranged bottom U-shaped plates 3, and a lower electric two-stage telescopic rod 9 is rotatably attached to the center of the lower rod 8. A middle rod 10 is provided between the two symmetrically arranged rear support rods 5, and the upper end of the lower electric two-stage telescopic rod 9 is rotatably connected to the middle rod 10.

[0009] A side rod 11 is provided between the two symmetrically arranged front support rods 4, and an upper electric two-stage telescopic rod 12 is rotatably provided on the side rod 11. A lower limb muscle spasm relaxation mechanism 13 is rotatably provided between the two symmetrically arranged upper U-shaped plates 6, and the front lower side of the lower limb muscle spasm relaxation mechanism 13 is rotatably connected to the upper end of the upper electric two-stage telescopic rod 12. A storage battery 14 is provided inside the middle connecting plate 1, and a controller 15 is disposed on the side of one of the upper U-shaped plates 6 of the height adjustment mechanism 2. The controller 15 is electrically connected to the storage battery 14, and also to the lower electric two-stage telescopic rod 9 and the upper electric two-stage telescopic rod 12. The storage battery 14 is a rechargeable lithium ion battery. The auxiliary U-shaped plate 7 and the bottom U-shaped plate 3, which are interconnected on the same side, are provided with lower support pads 16. The upper end of the lower core portion 17 of the upper electric two-stage telescopic rod 12 is rotatably connected to the side rod 11. The lower limb muscle spasm relief mechanism 13 includes a core arc-shaped support plate 18, a massage section 19 provided inside the core arc-shaped support plate 18, and a fixing belt 20 provided on the top of the core arc-shaped support plate 18. A plurality of fixing belts 20 are provided, and are evenly arranged along the longitudinal direction of the core arc-shaped support plate 18. Both ends of the core arc-shaped support plate 18 are rotatably connected to the ends of the two upper U-shaped plates 6 symmetrically arranged. The other end of the core arc-shaped support plate 18 is rotatably connected to the upper end of the upper electric two-stage telescopic rod 12 . The extending direction of the bottom U-shaped plate 3 and the extending direction of the upper U-shaped plate 6 are parallel to each other, and the extending direction of the front support rod 4 and the extending direction of the rear support rod 5 are also parallel to each other.

[0010] In concrete terms, when a patient is sitting in a chair undergoing hemodialysis or the like, a medical professional uses the device to relieve tension in the patient's lower limb muscles. By placing the patient's lower legs on the lower limb muscle spasm relief mechanism 13, fixing them securely with the fixing belt 20, and massaging them with the massage unit 19, it is possible to effectively prevent cramps and spasms in the lower legs. A medical professional can adjust the height of the lower limb muscle spasm relief mechanism 13 according to the patient's condition and posture. To adjust the height, a controller 15 is used to control the lower electric two-stage telescopic rod 9, which rotates the lower rod 8 to adjust the height of the upper U-shaped plate 6. The extension direction of the auxiliary U-shaped plate 7 is the same as that of the bottom U-shaped plate 3. A lower rod 8 is attached to the end of each of the two symmetrically arranged bottom U-shaped plates 3, and a lower electric two-stage telescopic rod 9 is rotatably attached to the center of the lower rod 8. A middle rod 10 is attached between each of the two symmetrically arranged rear support rods 5, and the upper end of the lower electric two-stage telescopic rod 9 is connected to the middle rod 10. The extension directions of the bottom U-shaped plate 3 and the upper U-shaped plate 6 are parallel to each other, and the extension directions of the front support rod 4 and the rear support rod 5 are also parallel to each other, providing high stability when adjusting the height of this device. Furthermore, medical personnel can adjust the angle of the lower limb muscle spasm relaxation mechanism 13 according to the patient's condition and posture. When adjusting the angle, the controller 15 controls the extension and retraction of the upper electric two-stage telescopic rod 12, thereby achieving angle adjustment of the lower limb muscle spasm relaxation mechanism 13. This device has a novel structure and distinctive design, and can effectively prevent cramps and spasms in the lower legs by placing the patient's lower legs on the lower leg muscle spasm relief mechanism 13, securely fixing them with the fixing belt 20, and massaging them with the massage unit 19. Furthermore, the height and angle of the lower leg muscle spasm relief mechanism 13 can be adjusted according to the patient's condition and posture, making it easy to operate, highly usable, and highly practical, and worthy of widespread use.
