Description

Technical Field

[0001] This application relates to the field of limb training technology, and in particular to a limb function recovery training device after illness. Background Technology

[0002] The core of postoperative lower limb rehabilitation training is to gradually restore function, including relieving pain and swelling, restoring joint mobility, strengthening muscles, rebuilding balance and gait, and finally returning to daily activities. Postoperative lower limb training requires the use of training devices for assisted training.

[0003] Existing training devices have a relatively simple training method when performing lower limb assisted training, resulting in poor postoperative lower limb training effects. During seated leg extension and knee flexion training, the patient's back remains against the chair back without moving, which affects blood circulation.

[0004] Therefore, those skilled in the art have provided a post-illness limb function recovery training device to solve the problems mentioned in the background art. Utility Model Content

[0005] In order to solve the problems mentioned in the background art, this application provides a limb function recovery training device after illness.

[0006] The technical solution of the post-illness limb function recovery training device provided in this application is as follows:

[0007] A post-illness limb function recovery training device includes a base frame, a seat cushion fixed to the upper end of the base frame, and a fixing frame fixed to one end of the base frame. Two slides are fixed to the upper end of the fixing frame, and the lower right end of each slide is fixedly connected to the base frame. Each slide is slidably connected to a slider, and each slider is rotatably connected to a rotating rod. A crossbar is fixed between the two rotating rods, and two sliding seats are slidably connected to the crossbar. Soft foot covers are fixed to the upper ends of each sliding seat. A support plate is fixed to the rear end of the seat cushion, and a rotating shaft is rotatably connected to the support plate. A backrest is fixed to the rotating shaft, and a torsion spring connects the rotating shaft and the support plate. An adjustment plate is installed on one side of the support plate.

[0008] Preferably, a Y-shaped support is fixed to the upper end of the base frame, two fixed pulleys are rotatably connected to the end of the support, a steel cable is fixed to one end of the crossbar, the steel cable is rolled between the two fixed pulleys, and a counterweight is installed at the bottom end of the steel cable.

[0009] Preferably, a threaded rod is fixed to the bottom end of the steel cable, and the threaded rod is threadedly connected to the counterweight.

[0010] Preferably, a spring is fixed between the sliding seat and the inner wall of the crossbar, and a bolt is threadedly connected to the upper end of the slider, with the lower end of the bolt contacting the upper surface of the rotating rod.

[0011] Preferably, the seat cushion is fixed with two armrests, and a limiting block is fixed to the end of the seat cushion, the limiting block being in contact with one side of the backrest.

[0012] Preferably, the lower end of the adjusting plate is horizontally slidably connected to the support plate, the support plate is rotatably connected to a screw, and the lower end of the adjusting plate is threadedly connected to the screw.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. This application allows patients to perform lower limb exercises such as leg extension and knee flexion by moving forward and backward using soft foot sleeves and a crossbar after surgery. This improves knee joint mobility, prevents postoperative joint stiffness, and improves hip joint mobility and lower limb stability by separating and bringing the two soft foot sleeves together, opening the feet to the sides, and then bringing them back together. This further enhances the effectiveness of postoperative lower limb rehabilitation training.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-3As shown, this application discloses a post-illness limb function recovery training device, including a base frame 1, a seat cushion 10 fixed to the upper end of the base frame 1, and a fixing frame 2 fixed to one end of the base frame 1. Two slides 5 are fixed to the upper end of the fixing frame 2. The lower right end of the slides 5 is fixedly connected to the base frame 1. Each slide 5 is slidably connected to a slider 6. Each slider 6 is rotatably connected to a rotating rod 20. A crossbar 3 is fixed between the two rotating rods 20. The crossbar 3 is slidably connected to two sliding seats 4. Soft foot covers 7 are fixed to the upper end of each of the two sliding seats 4. The seat cushion 1... A support plate 14 is fixed to the tail end, and a rotating shaft 24 is rotatably connected to the support plate 14. A backrest 12 is fixed to the rotating shaft 24, and a torsion spring 23 connects the rotating shaft 24 and the support plate 14. An adjustment plate 15 is installed on one side of the support plate 14. During postoperative training, the patient sits on the cushion 10 with their back against the backrest 12. The toes of both feet are inserted into the two soft foot covers 7, and then the patient uses their leg strength to push their feet forward until their knees are straight, thus fixing the soft foot covers 7, the crossbar 3, and the two sliders 6 in place. Move the frame in direction 2, then move both feet backward to return to their original position, causing the soft foot covers 7, crossbar 3, and two sliders 6 to move towards the seat cushion 10, bending and arching the knee joint. Repeat the movement of moving both feet forward and backward, alternating repeatedly, to exercise the quadriceps femoris muscles on the front of the thigh (when extending the leg) and the hamstring muscles on the back of the thigh (when bending the knee), strengthening leg muscles, improving knee joint mobility, and preventing postoperative joint stiffness. The training in the seated position has low load and high safety, making it suitable for the mid-term postoperative period (after the wound has basically healed and the swelling has subsided), especially suitable for people who need to restore lower limb function after knee, thigh, or hip surgery. In addition, when the patient's feet are inserted into the two soft foot covers respectively, the two feet can be moved away from each other, causing the two soft foot covers 7 to move away from each other, causing the two sliders 4 to slide apart on the crossbar 3. Then, the two feet can be moved closer together, causing the two soft foot covers 7 to move closer together, training the abductor and adductor muscle groups around the hip joint, while improving hip joint mobility and lower limb stability, which is beneficial for the patient's postoperative limb rehabilitation training.

[0021] Furthermore, the backrest 12 is rotatably connected to the support plate 14 via the rotating shaft 24. When the patient's back is against the backrest 12 to train lower limb extension, the back can slightly compress the backrest 12, pushing the backrest 12 to rotate clockwise until the back touches the adjustment plate 15, causing the torsion spring 23 to generate elasticity. Then, when training lower limb knee flexion, the backrest 12 can be slowly rotated counterclockwise to return to its original position with the assistance of the elasticity of the torsion spring 23, thus moving the back. In this way, while training the lower limbs, the patient's upper body can also move slightly to train, avoiding the upper body from leaning against the backrest 12 in the same position for a long time, thus avoiding affecting the blood circulation of the upper body.

[0022] To increase the resistance to movement of the crossbar 3, a Y-shaped support 9 is fixed to the upper end of the base frame 1. Two fixed pulleys 8 are rotatably connected to the end of the support 9. A steel cable 17 is fixed to one end of the crossbar 3. The steel cable 17 is rolled between the two fixed pulleys 8. A counterweight 18 is installed at the bottom of the steel cable 17. When the patient exercises the lower limb extension and pushes the soft foot cover 7 and the crossbar 3 towards the fixed frame 2, it pushes the steel cable 17 to move and pulls the counterweight 18 upward. The weight of the counterweight 18 increases the resistance to movement of the crossbar 3 and increases the intensity of lower limb training. When the patient flexes the knee, the weight of the counterweight 18 pulls the crossbar 3 towards the seat cushion 10, assisting the patient's knee flexion movement and facilitating lower limb training.

[0023] A threaded rod 19 is fixed to the bottom end of the steel cable 17. The threaded rod 19 is threadedly connected to the counterweight 18. The threaded rod 19 and the counterweight 18 can be rotated and disassembled. Different weights of counterweights 18 can be selected and installed on the threaded rod 19 according to the patient's postoperative time to assist in lower limb training.

[0024] A spring 22 is fixed between the sliding seat 4 and the inner wall of the crossbar 3. A bolt 21 is threadedly connected to the upper end of the slider 6, and the lower end of the bolt 21 contacts the upper surface of the rotating rod 20. In order to increase the sliding resistance of the sliding seat 4, a spring 22 is set between the sliding seat 4 and the inner wall of the crossbar 3 to increase the resistance of the patient's two feet separating and approaching in the horizontal direction. The crossbar 3 is rotated with the slider 6 through the rotating rod 20. In this way, during the movement of the patient's two feet, the crossbar 3 rotates to adapt to the leg extension and knee flexion movements. The setting of the bolt 21 increases the rotation resistance of the rotating rod 20.

[0025] The seat cushion 10 is fixed with two armrests 16. A limit block 11 is fixed to the end of the seat cushion 10, and the limit block 11 contacts one side of the backrest 12. When the patient sits on the seat cushion 10 to train the lower limbs, he / she can hold the armrests 16 to assist in the training. The limit block 11 and the adjustment plate 15 are used to adjust the rotation range of the backrest 12.

[0026] The lower end of the adjusting plate 15 is horizontally slidably connected to the support plate 14. The support plate 14 is rotatably connected to the screw 13, and the lower end of the adjusting plate 15 is threadedly connected to the screw 13. By rotating the screw 13, the adjusting plate 15 moves and adjusts its position on the support plate 14, thereby adjusting the clockwise rotation range of the backrest 12 to assist the patient in moving their upper body for training.

[0027] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] Working principle: The patient sits on the seat cushion 10 with their back against the backrest 12. The toes of both feet are inserted into the two soft foot covers 7. Then, using leg strength, the patient moves both feet forward until the knees are straight, causing the soft foot covers 7, the crossbar 3, and the two sliders 6 to move towards the fixed frame 2. Then, the patient moves both feet backward to return to their original position, causing the soft foot covers 7, the crossbar 3, and the two sliders 6 to move towards the seat cushion 10, causing the knees to bend and arch. The patient repeats the forward and backward movements of both feet, alternating between them, to train the lower limbs. In addition, when the patient's feet are inserted into the two soft foot covers, the patient can move their feet away from each other, causing the two soft foot covers 7 to move away from each other, causing the two sliding seats 4 to slide apart on the crossbar 3. Then, the patient moves their feet closer together, causing the two soft foot covers 7 to move closer together. This trains the abductor and adductor muscles around the hip joint, and at the same time improves hip joint mobility and lower limb stability, which is beneficial for the patient's postoperative limb rehabilitation training.
