[0002] In neurosurgery, there is a disease called hemiplegia. Hemiplegia, also known as hemiparalysis, refers to the motor disorders of the same-side upper and lower limbs, facial muscles, and the lower part of the tongue muscles. It is a common symptom of acute cerebrovascular diseases. In the rehabilitation treatment of hemiplegic patients, patients need to keep moving their limbs regularly to maintain the recovery of physical functions. Usually, in the early stage of rehabilitation, a walking aid is used to assist patients in lower limb movement. The following problems exist in the prior art:
[0003] When the existing movement nursing device uses a walking aid to assist movement, the patient needs to support the walking aid with the upper limbs. However, the lower limb strength of patients is generally weak in the early stage of rehabilitation. Therefore, the upper limbs of the patient need to bear greater pressure, resulting in fatigue of the upper limbs after assisting movement, and even the risk of the patient falling due to sudden insufficient strength of the upper limbs.

Specific embodiments
[0019] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] Such as Figure 1 、 Figure 2 、 Figure 3As shown in the figure, the utility model provides a nursing device for assisting patients' limb movement, including a body protection bed board 1. A support backrest board 2 is movably installed in the middle of the top end of the body protection bed board 1. A seating cushion 3 is fixedly installed on the front side of the top of the body protection bed board 1. Extension drive rods 11 are fixedly installed on the left and right sides of the front end of the body protection bed board 1. A limit extension rod 12 is fixedly installed in the middle of the front end of the body protection bed board 1. Lower limb bending movement mechanisms 4 are arranged between the left and right sides of the two extension drive rods 11 and the limit extension rod 12. Motor cabins 111 are opened inside the two extension drive rods 11. Drive motors 112 are fixedly installed on the front side inner walls of the two motor cabins 111. The drive motors 112 adopt a brushless DC motor design, and the two drive motors 112 can be separately controlled and their speeds can be controlled to achieve separate and different folding movement speed control of the two lower limb bending movement mechanisms 4. Moving chutes 113 are opened on the sides of the two extension drive rods 11 close to the limit extension rod 12. The output shafts of the two drive motors 112 respectively penetrate into the inner cavities of the two moving chutes 113 and are fixedly installed with reciprocating lead screws 114. Limit chutes 121 are opened on the left and right sides of the limit extension rod 12. The two lower limb bending movement mechanisms 4 both include thigh support plates 41. The rearmost sides of the left and right ends of the two thigh support plates 41 are respectively movably connected to the rearmost sides between the left and right sides of the two extension drive rods 11 and the limit extension rod 12. Calf support plates 42 are movably installed on the front sides of the two thigh support plates 41. Moving pulleys 45 are movably installed on the foremost sides of the opposite surfaces of the two calf support plates 42. The two moving pulleys 45 are respectively slidably connected to the two limit chutes 121. Drive moving blocks 44 are movably installed on the foremost sides of the opposite surfaces of the two calf support plates 42. The two drive moving blocks 44 are respectively threadedly connected to the two reciprocating lead screws 114. Limit sponge strips 43 are fixedly installed on the left and right sides of the tops of the two thigh support plates 41 and the calf support plates 42;
[0021] When rehabilitation exercises are needed for the patient's lower limbs, the patient can sit on the seating cushion 3 on the protective bed board 1, lean back against the support backrest board 2, and then place the two lower limbs on the lower limb bending exercise mechanism 4. The thigh part is placed on the thigh support board 41, and the calf part is placed on the calf support board 42. The limiting sponge strips 43 on the left and right sides of the surfaces of the thigh support board 41 and the calf support board 42 are used to support the left and right sides of the lower limbs to prevent slipping left and right. Then, the drive motors 112 in the motor cabins 111 opened inside the two extension drive rods 11 can be started by remote control. The drive motors 112 in the two extension drive rods 11 can be respectively controlled to start. Thus, the reciprocating lead screws 114 in the two moving chutes 113 are threadedly connected to the drive moving blocks 44 on the back surfaces of the two calf support boards 42 to make the drive moving blocks 44 move backward, so that the calf support board 42 as a whole moves backward and folds with the thigh support board 41. When reaching the rearmost end, the reciprocating lead screw 114 will move forward again, achieving the effect of simulating the bending movement of the patient's lower limbs. When the drive moving block 44 moves to the frontmost side of the moving chute 113, the thigh support board 41 and the calf support board 42 still maintain an obtuse angle to avoid the situation of folding downward. At the same time, when the calf support board 42 moves, the moving pulley 45 slides in the limiting chute 121 to maintain the smoothness and stability of the movement of the calf support board 42.
[0022] As Figure 4 shown, limiting straps 421 are fixedly installed on the back surfaces of the two calf support boards 42 and the thigh support board 41, and hook surfaces of Velcro 423 are fixedly installed on the opposite surfaces of the two calf support boards 42 and the thigh support board 41. Magic tape surfaces 422 are fixedly installed at the bottoms of the four limiting straps 421.
[0023] As Figure 5 shown, an electric push rod 13 is fixedly installed at the rear side of the bottom of the protective bed board 1. The output end of the electric push rod 13 penetrates to the top of the protective bed board 1 and is movably installed with a movable shaft 131. A chute 21 is opened at the rear side of the support backrest board 2, and the front side of the movable shaft 131 is slidably connected to the chute 21;
[0024] To improve the comfort of the patient during use, the electric push rod 13 can be started by remote control to drive the movable shaft 131 to rise and slide upward in the chute 21 at the rear side of the support backrest board 2, so that the angle of the overall support backrest board 2 can be adjusted to improve the comfort of the patient when leaning back against the support backrest board 2.
[0025] Next, the working principle of the nursing device for assisting the patient's limb movement will be specifically described.
[0026] As Figures 1-5As shown in the figure, when the lower limbs of the patient need to perform rehabilitation exercises, the patient can sit on the seating cushion 3 on the protective bed board 1, lean against the support backrest board 2, and then place the two lower limbs on the lower limb bending exercise mechanism 4. The thigh part is placed on the thigh support board 41, and the calf part is placed on the calf support board 42. The limiting sponge strips 43 on the left and right sides of the surfaces of the thigh support board 41 and the calf support board 42 are used to support the left and right sides of the lower limbs to prevent slipping. Then, by using the adhesion of the hook surface 423 of the magic tape to the loop surface 422 of the magic tape at the bottom of the limiting strap 421, the lower leg and thigh parts of the patient's lower limbs can be fixed to the thigh support board 41 and the calf support board 42 respectively, preventing the legs from uncontrollably detaching from the lower limb bending exercise mechanism 4 during the movement. Then, the drive motors 112 in the motor compartments 111 opened inside the two extension drive rods 11 can be started by remote control. The drive motors 112 in the two extension drive rods 11 can be controlled to start respectively. Thus, the reciprocating lead screws 114 in the two moving chutes 113 are threadedly connected to the drive moving blocks 44 on the back surfaces of the two calf support boards 42 to make the drive moving blocks 44 move backward, so that the calf support board 42 as a whole moves backward and folds with the thigh support board 41, achieving the effect of simulating the bending movement of the patient's lower limbs. At the same time, when the calf support board 42 moves, the moving pulley 45 slides in the limiting chute 121 to maintain the smoothness and stability of the movement of the calf support board 42. At the same time, in order to improve the comfort of the patient during use, the electric push rod 13 can be started by remote control to drive the movable shaft 131 to rise and slide upward in the chute 21 at the rear of the support backrest board 2, so that the angle of the overall support backrest board 2 can be adjusted to improve the comfort of the patient when leaning against the support backrest board 2.
[0027] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
