[0002] Hemiplegia, also known as hemiparalysis, refers to the motor disorders of the upper and lower limbs, facial muscles and lower part of the tongue muscle on the same side, and is a common symptom of acute cerebrovascular diseases. Although mild hemiplegic patients can still move, when walking, their upper limbs are often flexed and their lower limbs are straightened. The paralyzed lower limb takes a half-circle when taking a step. This special walking posture is called hemiplegic gait. When hemiplegic patients are undergoing rehabilitation training, the most effective training method is walking, and when training, auxiliary tools are needed to ensure the balance of patients. The following problems exist in the prior art:
[0003] Because existing hemiplegic patients often use walking aids for assisted walking during rehabilitation treatment, and this kind of walking aid has a relatively simple structure and is composed of several steel pipes, it cannot be adjusted according to patients of different heights and body types, resulting in poor applicability. When it does not match the patient's body shape, the patient feels uncomfortable when using it. Content of the Utility Model

[0021] To make the technical means, creative features, achieved purposes, and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] Such asFigure 1 , Figure 2 As shown in Figure 2 , the utility model provides a walking assistor for hemiplegic patients, which includes two portal steel pipe brackets 1. A width adjustment mechanism 3 is arranged between the opposite surfaces of the front vertical parts of the two portal steel pipe brackets 1. Pulley 2 is movably installed at the lowermost part of the front vertical part of each of the two portal steel pipe brackets 1. Axillary support mechanisms 4 are fixedly installed at the rear sides of the rear vertical parts of the two portal steel pipe brackets 1. Adjusting armrest mechanisms 5 are fixedly installed at the horizontal parts of the two portal steel pipe brackets 1. The width adjustment mechanism 3 includes a limit post 35, a fixed cylinder 38, and two fixed pipes 31. The opposite ends of the two fixed pipes 31 are respectively fixedly connected to the opposite surfaces of the front vertical parts of the two portal steel pipe brackets 1. Threaded inner walls 32 are provided on the opposite surfaces of the two fixed pipes 31. Width threaded rods 33 are threadedly installed in the inner circles of the two threaded inner walls 32. Rotating connection columns 34 are fixedly installed at the opposite ends of the two width threaded rods 33. The limit post 35 and the fixed cylinder 38 are both located below the two fixed pipes 31. A slide bar 36 is fixedly installed at the left end of the limit post 35. The left end of the slide bar 36 penetrates into the inner cavity of the fixed cylinder 38 and a limit disk 37 is fixedly installed. The outer wall of the limit disk 37 is slidably connected to the inner wall of the fixed cylinder 38;
[0023] When in use, the patient can place the armpit against the top of the axillary support mechanism 4, and then place the hand on the adjusting armrest mechanism 5. Each time when walking forward, the portal steel pipe bracket 1 can be used for support. At the same time, when moving the portal steel pipe bracket 1 forward, the pulley 2 at the bottom of the front vertical part of the portal steel pipe bracket 1 can slide on the ground, thereby improving the smoothness of forward movement and making the forward movement more labor-saving. When it is necessary to adjust the distance between the two portal steel pipe brackets 1, by rotating the rotating connection column 34 between the two fixed pipes 31, the two width threaded rods 33 with opposite outer wall threads make the two fixed pipes 31 drive the two portal steel pipe brackets 1 to move to both sides through the threaded connection with the threaded inner wall 32 of the fixed pipe 31. At the same time, when moving, the stability is maintained by the sliding of the slide bar 36 at the left end of the limit post 35 in the fixed cylinder 38, and the separation of the two portal steel pipe brackets 1 is prevented by relying on the limit disk 37. Finally, the width adjustment of the two portal steel pipe brackets 1 is completed, which is convenient for adapting to patients with a larger body size.
[0024] As Figure 3As shown in the figure, both of the two axillary support mechanisms 4 include adjustment boxes 41. The two adjustment boxes 41 are respectively fixedly connected to the vertical parts at the rear side of the portal steel pipe support 1. On the front side of the bottom inner walls of the two adjustment boxes 41, lifting lead screws 42 are movably installed. The tops of the two lifting lead screws 42 respectively penetrate through the tops of the two adjustment boxes 41 and are fixedly installed with knobs 43. Threaded lifting plates 44 are installed on the outer walls of the two lifting lead screws 42. On the rear sides of the tops of the two lifting plates 44, lifting columns 45 are fixedly installed. The two lifting plates 44 are respectively slidably connected to the inner walls of the two adjustment boxes 41. The tops of the two lifting columns 45 respectively penetrate through the tops of the two adjustment boxes 41 and are fixedly installed with U-shaped rods 46. On the tops of the two U-shaped rods 46, axillary support plates 47 are fixedly installed. On the tops of the two axillary support plates 47, memory foam pads 48 are fixedly installed. The tops of the two memory foam pads 48 are designed to be arc-shaped, which is more suitable for fitting under the patient's armpits.
[0025] By respectively rotating the knobs 43 on the tops of the two adjustment boxes 41 to drive the lifting lead screws 42 to rotate, the lifting columns 45 are driven to move upward by using the threaded connection between the lifting lead screws 42 and the lifting plates 44, so as to adjust the height of the axillary support plates 47 on the tops of the U-shaped rods 46. When the patient presses on the memory foam pads 48 supported on the tops of the axillary support plates 47, it will be more comfortable, thus adapting to patients of different heights.
[0026] As Figure 4 、 Figure 5 shown in the figure, both of the two adjustable armrest mechanisms 5 include fixed sleeves 51. The two fixed sleeves 51 are respectively fixedly installed on the outer walls at the horizontal parts of the two portal steel pipe supports 1. On the opposite sides of the two fixed sleeves 51, extension plates 52 are fixedly installed. Threaded holes penetrating up and down are opened in the two extension plates 52. Threaded rods 53 are installed in the inner circles of the two threaded holes. At the bottom ends of the two threaded rods 53, adjustment knobs 54 are fixedly installed. At the top ends of the two threaded rods 53, left-right adjustment boxes 55 are movably installed. On the sides close to the fixed sleeves 51 on the left and right sides of the two left-right adjustment boxes 55, limit sliding plates 56 are fixedly installed. On the front and rear sides at the tops of the two fixed sleeves 51, limit sliding rods 57 are fixedly installed. The limit sliding plates 56 are slidably connected to the limit sliding rods 57. On the tops of the two left-right adjustment boxes 55, sliding grooves 551 are opened. On the opposite sides of the inner walls of the two sliding grooves 551, adjustment threaded rods 552 are movably installed. The other ends of the two adjustment threaded rods 552 respectively penetrate through the opposite sides of the two left-right adjustment boxes 55 and are fixedly installed with control knobs 553. Threaded translation vertical plates 554 are installed on the outer walls of the two adjustment threaded rods 552. On the upper parts of the front and rear sides of the two translation vertical plates 554, L-shaped brackets 555 are fixedly installed. At the top ends of the vertical parts of the L-shaped brackets 555, handrails 556 are fixedly installed. Anti-slip rubber sleeves 557 are fixedly installed on the outer walls of the two handrails 556.
[0027] By rotating the two adjustment knobs 54 on the left and right sides, the threaded rod 53 is driven to rotate and rise, so that the left and right adjustment boxes 55 use the sliding connection limit between the limit slide plate 56 and the limit slide rod 57 to move stably upward, better adapting to the upper limbs of patients with different lengths. At the same time, the control knob 553 can be rotated to drive the adjustment threaded rod 552 to rotate, so that the translation vertical plate 554 moves left and right by using the threaded connection with the adjustment threaded rod 552, adjusting the handrail 556 at the top of the L-shaped bracket 555 held by the patient to different positions left and right, and using the anti-slip rubber sleeve 557 on the outer wall of the handrail 556 to increase the friction with the patient's hand, preventing the hand from slipping and improving safety.
[0028] Next, the working principle of the walking assist device for hemiplegic patients will be specifically described.
[0029] As Figures 1-5 shown, when in use, the patient can place the armpit against the top of the axillary support mechanism 4, and then place the hand on the adjustment armrest mechanism 5. Each time walking forward, the gantry steel pipe bracket 1 can be used for support. At the same time, when moving the gantry steel pipe bracket 1 forward, the pulley 2 at the bottom of the front vertical part of the gantry steel pipe bracket 1 can slide on the ground, thereby improving the smoothness of forward movement and making forward movement more labor-saving. When it is necessary to adjust the distance between the two gantry steel pipe brackets 1, by rotating the rotary connection column 34 between the two fixed pipes 31, the two width threaded rods 33 with opposite outer wall threads move the two gantry steel pipe brackets 1 to both sides by using the threaded connection with the inner threaded wall 32 of the fixed pipe 31. At the same time, when moving, the left end slide rod 36 of the limit post 35 slides in the fixed cylinder 38 to maintain stability, and the two gantry steel pipe brackets 1 are prevented from separating by relying on the limit disc 37, finally completing the width adjustment of the two gantry steel pipe brackets 1, facilitating adaptation to patients with larger body types. Then, by rotating the knobs 43 on the tops of the two adjustment boxes 41 respectively, the lifting screw rod 42 can be driven to rotate, so that the lifting column 45 moves upward by using the threaded connection between the lifting screw rod 42 and the lifting plate 44, adjusting the height of the axillary support plate 47 at the top of the U-shaped rod 46. When the patient presses on the memory foam pad 48 supported on the top of the axillary support plate 47, it will be more comfortable, thus adapting to patients of different heights. Moreover, the height of the armrest can also be adjusted by rotating the two adjustment knobs 54 on the left and right sides, driving the threaded rod 53 to rotate and rise, so that the left and right adjustment boxes 55 use the sliding connection limit between the limit slide plate 56 and the limit slide rod 57 to move stably upward, better adapting to the upper limbs of patients with different lengths. At the same time, the control knob 553 can be rotated to drive the adjustment threaded rod 552 to rotate, so that the translation vertical plate 554 moves left and right by using the threaded connection with the adjustment threaded rod 552, adjusting the handrail 556 at the top of the L-shaped bracket 555 held by the patient to different positions left and right, and using the anti-slip rubber sleeve 557 on the outer wall of the handrail 556 to increase the friction with the patient's hand, preventing the hand from slipping and improving safety.
[0030] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made thereto, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit and idea of the present utility model are within the protection scope of the present utility model.
