Description

Technical Field

[0001] This utility model relates to a walking aid, specifically a walking aid for hemiplegic rehabilitation. Background Technology

[0002] Hemiplegia is a motor dysfunction of one side of the body caused by stroke, brain injury, or neurological disease. Rehabilitation treatment focuses on early intervention and multidisciplinary collaboration. It restores muscle strength and coordination through physical therapy, improves daily living skills through occupational therapy, and is supplemented by gait training, neural remodeling technology, and intelligent rehabilitation equipment to gradually rebuild neural function compensation and ultimately achieve the greatest possible recovery of motor function and improvement of independent living ability.

[0003] A known authorized patent with application number 202322785548.9 discloses a walking aid for hemiplegic rehabilitation and nursing: a backrest, a base at the bottom of the backrest, four supports at the bottom of the base, two of the supports at the bottom of the backrest having two walking wheels, and the other two supports having omnidirectional wheels at the bottom of the omnidirectional wheels, with rotating foot supports on the upper part of the omnidirectional wheels, a safety belt on one side of the backrest, and a push handle on the other side, a safety belt buckle on the upper side of the base, the safety belt buckle and the safety belt being located on opposite sides, and handrails on both sides of the base. The advantage of this utility model is that the walking wheels and omnidirectional wheels increase the stability and mobility of the walking aid, allowing patients to move and change direction more easily, and the height-adjustable handrails help to adapt to the body shape and needs of different patients.

[0020] Please see Figure 1 -4. The hemiplegic rehabilitation walking aid of this embodiment includes: a support frame 1, a seating mechanism 2, a walking mechanism 3, a lower limb exercise mechanism 4, and an upper limb exercise mechanism 5; wherein, the support frame 1 is the main structure and mainly plays the role of overall support; the seating mechanism 2 is set above the support frame 1 for the user to sit on; the walking mechanism 3 is rotatably connected to both sides of the support frame 1 to provide overall mobility, i.e., walking assistance; the lower limb exercise mechanism 4 is hinged to the outer wall of the support frame 1 for the user to perform lower limb exercises; the upper limb exercise mechanism 5 is hinged to both sides of the support frame 1 for the user to perform upper limb exercises.

[0021] The seating mechanism 2 includes a seat cushion 21, a backrest 22, side panels 23, and armrests 24. The seat cushion 21 is fixedly connected to the top of the support frame 1, the backrest 22 is fixedly connected to the outer surface of the support frame 1, the side panels 23 are located on both sides of the backrest 22, and the armrests 24 are located on both sides of the seat cushion 21. An elastic band 6 is provided on the inner wall of the backrest 22, and a push handle 7 is provided on the outer wall of the support frame 1, located behind the backrest 22. The armrests 24 and side panels 23 prevent the patient from accidentally falling due to lateral movement while sitting on the seating mechanism 2. The elastic band 6 provides the device with a certain amount of neck exercise capacity, providing sufficient neck exercise for the patient during the rehabilitation period and preventing symptoms such as weakness in head lifting due to muscle loss.

[0022] The walking mechanism 3 includes a support shaft 31, walking wheels 32, push wheels 33, and front wheels 34. The support shaft 31 is fixedly connected to the inside of the support frame 1. The walking wheels 32 are rotatably connected to both ends of the support shaft 31. Push wheels 33 are provided on the outer wall of the walking wheels 32, and the push wheels 33 are concentrically arranged with the walking wheels 32. The front wheels 34 are rotatably connected to both sides of the support frame 1. The push wheels 33 allow patients with hand movement ability to move freely while riding this device, giving them control over their movement.

[0023] The lower limb exercise mechanism 4 includes a support rod 41, a connecting block 42, a first hydraulic resistance adjusting rod 43, a guard plate 44, and a strap 45. The support rod 41 is fixedly connected to the inside of the support frame 1. The connecting block 42 is rotatably connected to the outer wall of the support rod 41. One end of the first hydraulic resistance adjusting rod 43 is fixedly connected to the outer wall of the connecting block 42, and the other end of the first hydraulic resistance adjusting rod 43 is rotatably connected to the inner wall of the guard plate 44. The top of the guard plate 44 is rotatably connected to the outer wall of the seat cushion 21. The strap 45 is located on the inner wall of the guard plate 44. Through the design of the lower limb exercise mechanism 4, this device provides effective leg exercise capabilities, effectively preventing muscle atrophy caused by prolonged inactivity of leg muscles.

[0024] The upper limb exercise mechanism 5 includes a connecting support block 51, a second hydraulic resistance adjusting rod 52, an arm placement plate 53, a hand strap 54, and a hand rest 55. One end of the connecting support block 51 is rotatably connected to the outer wall of the support frame 1. The second hydraulic resistance adjusting rod 52 is fixedly connected to the other end of the connecting support block 51. The arm placement plate 53 is fixedly connected to the output end of the second hydraulic resistance adjusting rod 52. The hand strap 54 is disposed on the inner wall of the arm placement plate 53, and the hand rest 55 is inserted into the inside of the handrail 24. Through the design of the upper limb exercise mechanism 5, this device possesses effective arm exercise capabilities, enabling patients to effectively exercise their arms and improving their rehabilitation outcomes.

[0025] In use, first place the patient on the seating mechanism 2, ensuring the patient's back is firmly against the backrest 22. When the patient needs to use the device independently, first remove the hand rest 55 to prevent it from obstructing the patient's arm movement. Then, rotate the push wheel 33 to drive the walking wheel 32, moving the device. When the patient needs to perform leg training, first place the legs on the guard plate 44, then secure the patient's legs with the straps 45. The patient then performs a leg-raising motion. Simultaneously, adjust the resistance of the first hydraulic resistance adjusting rod 43 according to the patient's strength. Too high or excessive resistance will not provide effective leg training. During the leg-raising motion, the first hydraulic resistance adjusting rod 43... The rotating connection of the support rod 41 avoids restricting the movement of the first hydraulic resistance adjustment rod 43, allowing the patient's legs to perform effective flexion and extension exercises. When arm exercises are needed, first insert the hand support 55 into the inner wall of the armrest 24, then place the elbow on the hand support 55, and then place the forearm or hand on the hand placement plate 53 and fix it with the hand strap 54. Then, the arm flexion and extension movements can be performed. Similarly, it should be able to adjust the resistance of the second hydraulic resistance adjustment rod 52, and the connecting support block 51 avoids restricting the movement path of the second hydraulic resistance adjustment rod 52. The elastic band 6 can achieve the function of exercising the neck. By wrapping the strap 6 around the patient's forehead and moving the head back and forth, the neck muscles can be exercised.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
