Description

Technical Field

[0001] This utility model belongs to the field of assistive technology for hemiplegic patients, and in particular relates to a gait correction device for hemiplegic patients. Background Technology

[0002] Hemiplegia, also known as paralysis of one side of the body, refers to motor dysfunction of one side of the upper and lower limbs, facial muscles, and lower tongue muscles. It is a common symptom of acute cerebrovascular disease. Patients with mild hemiplegia can still move, but when walking, they often walk with the upper limb flexed and the lower limb extended; this distinctive gait is called hemiplegic gait. Prolonged use of this gait by hemiplegic patients is detrimental to their recovery.

[0003] Currently, the common gait correction in hospitals involves medical staff or family members supporting the patient to stand. When the patient walks, medical staff intervene to correct the movement of the affected limb, adjusting its position and foot placement. Throughout the walking process, the patient needs to take steps independently, and their control over the affected limb is limited. The affected limb cannot fully complete the entire process of lifting the leg, bending the knee, stepping, and landing. In most cases, the healthy limb steps first, and then the patient slides along supporting the affected limb. Even with the intervention of medical staff, the gait correction effect is poor. Utility Model Content

[0004] The purpose of this invention is to provide a gait correction device for hemiplegic patients. It has a simple structure and the healthy limb moves the affected limb by bending the knee, thereby correcting the patient's gait.

[0005] The aforementioned gait correction device for hemiplegic patients includes a vertically arranged base plate, a support plate vertically fixed to the left side of the base plate, a shell vertically fixed to the front side wall of the base plate, a fixing plate fixed in the middle of the shell, and horizontally arranged sliding plates inside the shell on both sides of the fixing plate. A linkage component is provided in the middle of the fixing plate, which drives the other sliding plate to move in the opposite direction when one sliding plate moves. Two pulleys are installed on the left side wall of the support plate, and an elastic band is provided on the front side of each sliding plate. The two elastic bands are connected by a pull rope, which is wrapped around the two pulleys.

[0006] Furthermore, the linkage component includes a gear, and grooves are provided on the upper and lower side walls of the fixed plate along the length direction of the fixed plate. The side of the slide plate is independently inserted into the groove. A through groove communicating with the groove is provided in the middle of the fixed plate. The gear is installed in the through groove. A rack that meshes with the gear is installed on the side of the slide plate inserted into the groove.

[0007] Furthermore, the top of the housing has an inclined structure that is higher on the left and lower on the right.

[0008] Furthermore, a movable plate is detachably installed on the left side wall of the support plate, and pulleys are installed on the movable plate.

[0009] Furthermore, a pedal is fixed to the front side wall of the skateboard, and a strap is wrapped around the pedal.

[0010] Furthermore, a fixing rod is horizontally fixed to the right side wall of the support plate, and an extension plate is horizontally fixed to the right end of the fixing rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In this invention, the patient's healthy limb steps on one of the sliding boards, while the affected limb steps on the other. At the same time, two elastic bands are placed around the patient's knees. When the patient's healthy limb moves, the linkage component causes the affected limb to move in the opposite direction. Simultaneously, the healthy limb moves the elastic bands, and by pulling the rope, the elastic bands on the affected limb move, pulling the knee of the affected limb to make a knee flexion movement, thus performing gait correction training for the patient.

Figure 1 and Figure 2 As shown, it includes a vertically arranged base plate 4, a support plate 1 vertically fixed to the left side of the base plate 4, and the rear end of the support plate 1 fixed to the left end of the base plate 4. The support plate 1 is used for hand support during patient gait training.

[0018] The front sidewall of the base plate 4 is vertically fixed with a housing 5. The opening of the housing 5 faces forward. The housing 5 is used to install two sliding plates 9. The sliding plates 9 slide left and right inside the housing 5.

[0019] A fixing plate 7 is fixed in the middle of the housing 5. The left end of the fixing plate 7 is fixed to the left inner side wall of the housing 5, and the right end of the fixing plate 7 is fixed to the right inner side wall of the housing 5.

[0020] Two sliding plates 9 are horizontally arranged inside the housing 5 on both sides of the fixed plate 7. The upper sliding plate 9 is horizontally arranged inside the housing 5 above the fixed plate 7, and the lower sliding plate 9 is horizontally arranged inside the housing 5 below the fixed plate 7. The two sliding plates 9 slide left and right along the length of the housing 5, causing the patient's feet to move left and right.

[0021] Slide grooves 6 are provided on both the upper and lower sidewalls of the fixing plate 7 along its length. The side of the sliding plate 9 is independently inserted into the slide groove 6. The upper end of the fixing plate 7 has a downward slide groove 6, and the lower end of the fixing plate 7 has an upward slide groove 6. The slide grooves 6 are provided along the length of the fixing plate 7. The lower end of the upper sliding plate 9 is inserted into the upper slide groove 6, and the upper end of the lower sliding plate 9 is inserted into the lower slide groove 6 of the fixing plate 7. The sliding plate 9 slides left and right along the length of the slide groove 6 to ensure the stability of the sliding plate 9 during movement and to prevent the patient from falling. A through groove communicating with the slide groove 6 is provided in the middle of the fixing plate 7. The upper end of the through groove communicates with the upper slide groove 6, and the lower end of the through groove communicates with the lower slide groove 6. The gear 12 is installed in the through groove. Gear 12 is vertically installed in the through groove; a rack 8 that meshes with gear 12 is installed on the side of the slide plate 9 inserted into the slide groove 6. There are two racks 8. The upper rack 8 is horizontally fixed to the lower end of the upper slide plate 9, and the lower rack 8 is horizontally fixed to the upper end of the lower slide plate 9. Gear 12 meshes with rack 8. When gear 12 rotates, it drives rack 8 to move left and right. This paragraph as a whole constitutes a linkage component that drives the other slide plate 9 to move in the opposite direction when one slide plate 9 moves. When the linkage component is in use, when the upper slide plate 9 moves to the right, the upper rack 8 moves to the right, driving gear 12 to rotate clockwise. The rotation of gear 12 drives the lower rack 8 to move to the left, thereby driving slide plate 9 to move to the left, and driving the patient's affected limb to move through the patient's healthy limb.

[0022] Two pulleys 16 are installed on the left side wall of the support plate 1. Both pulleys 16 are fixed on the left side wall of the support plate 1. The two pulleys 16 are distributed vertically, with the upper pulley 16 facing the upper slide plate 9 and the lower pulley 16 facing the lower slide plate 9.
