Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation devices, in particular to a rehabilitation auxiliary device for lower limb training. Background Art

[0002] Currently, patients who have undergone lower limb orthopedic surgery usually need to undergo lower limb rehabilitation training after surgery to help patients recover better. Lower limb training and rehabilitation devices are indispensable equipment in the training process.

[0003] In the prior art, for example, announcement number CN217612735U proposes a lower limb rehabilitation auxiliary exercise device, comprising a base, a column is fixedly installed at the rear end of the top of the base, a mounting plate is provided in the inner cavity of the column, and a motor is fixedly installed on the top of the mounting plate; the utility model achieves the advantages of not requiring the constant accompaniment of nursing staff and facilitating rehabilitation training through the arrangement of columns, mounting plates, motors, active teeth, driven teeth, rotating rods, support plates, active wheels, driven wheels, rotating shafts, rocker arms, pedals, screw rods and sleeves, and solves the problem that the patient needs to rely on nursing staff throughout the entire rehabilitation training, which will have a certain impact on the patient's psychology, thereby reducing the patient's enthusiasm for training, and in the early stage of rehabilitation training, the patient's mobility is very weak, and it is difficult to walk even with the help of medical staff, making rehabilitation training difficult to carry out.

[0004] However, when the above solution is used, the nursing staff fixes the tightening belt on the patient's waist. Since the tightening belt cannot be scaled, when the nurse fixes an obese patient, the patient will be very tightly tied by the elastic band, and the patient's experience is relatively poor. When the nurse fixes a thin patient, the tightening belt appears to be very loose and cannot play a proper fixing role on the patient, resulting in low practicality of the device.

[0005] In order to solve the above problems, the present application proposes a rehabilitation auxiliary device for lower limb training. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides a rehabilitation auxiliary device for lower limb training, which solves the problem that the tightening belt cannot be scaled and thus the practicability of the device is low when fixing patients of different body shapes.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions:

[0008] The strap is adapted to engage the strap and engage the straps to engage the straps, wherein the straps are rotatably connected to the straps and the straps are secured to the straps with the straps being removable and removable so that the straps can be easily retracted.

[0009] 1. Working principle: The patient stands on the pedal of the device body with the assistance of the nurse. The nurse adjusts the position of the connecting frame so that one end of the two connecting frames is close to the patient's waist, limits the connecting frame through the limiting assembly, inserts the pin on one side of the second tightening belt into the buckle on the first tightening belt, pulls the stretching rod upward to drive the rectangular plug to slide upward along the guide bracket through the sliding rod, and when the rectangular plug is completely retracted into the inside of the guide bracket, the shrinkage cover is turned and opened. The nurse tightens the second tightening belt according to the patient's body shape and places the second tightening belt into the shrinkage box, and pulls the stretching rod upward while turning the shrinkage cover to drive the rectangular plug to move upward. When the rectangular plug is completely retracted into the inside of the guide bracket, press the shrinkage cover hard to tighten the second tightening belt, and then press the stretching rod downward. When the rectangular plug and the limiting groove are connected, the device can be used normally.

[0010] 2. Beneficial effects: The connecting frame is slidably connected to the device body, which can better adjust the distance between the two connecting frames, so that the device can adapt to more patients of different body shapes. By setting a contraction box at one end of the first tightening belt, the nurse adjusts the looseness of the first tightening belt and the second tightening belt, and then places the second tightening belt into the contraction box, and tightens the second tightening belt through the stabilizing block, so that the first tightening belt and the second tightening belt fit the patient's waist more closely.

[0011] Preferably, the limiting assembly includes wedge-shaped blocks slidably connected to both sides of the device body, and a plurality of triangular notches matching the wedge-shaped blocks are provided on the top of the connecting frame, and the triangular notches are evenly distributed on the top of the connecting frame in a linear array. After the patient enters the device, the nurse slides the connecting frame so that the connecting frame is close to the patient's waist. The nurse slides the wedge-shaped blocks to engage with the corresponding triangular notches, which can play a better limiting role on the connecting frame, so that the device can be suitable for patients of more different body shapes.

[0012] Preferably, a plurality of protrusions are fixedly connected to one side of the inner wall of the shrinkage box, and a groove matching the protrusion is provided on the side of the stabilizing block away from the shrinkage cover. The plurality of protrusions are combined to be arranged in a wave shape. When the nurse places the second tightening belt into the shrinkage box, the contact area between the stabilizing block and the second tightening belt is increased by fixing the plurality of protrusions on one side of the inner wall of the shrinkage box and providing matching grooves on the shrinkage cover, thereby increasing the friction force and improving the fixing ability of the shrinkage box to the second tightening belt.

[0013] Preferably, the outer wall of the sliding rod is provided with a compression spring, one end of the compression spring is fixedly connected to the rectangular plug block, and the other end of the compression spring is fixedly connected to the top of the inner wall of the shrinkage box. When the patient uses the device, the compression spring is in a compressed state. After the stretching rod is released, the compression spring can provide a stable thrust for the rectangular plug block, so that the rectangular plug block and the limit groove are clamped, which can effectively improve the stability of the shrinkage box.

[0014] Preferably, the side of the stabilizing block close to the limiting groove is chamfered. The side of the stabilizing block close to the limiting groove is chamfered so that when the medical staff presses the retractable cover, the chamfered surface of the stabilizing block can squeeze the rectangular plug block to slide inside the guide bracket. The advantage of this arrangement is that the medical staff does not need to keep pulling the stretching rod. When the lower end surface of the rectangular plug block coincides with the limiting groove, the rectangular plug block is snapped into the limiting groove under the elastic force of the compression spring, thereby completing the fixation of the second tightening belt.

[0015] Preferably, the second tightening belt is fixedly connected to one end away from the pin with Velcro, the Velcro fur surface is fixed to the lower end of one side of the Velcro, and the Velcro hook surface is fixed to the upper end of the other side of the Velcro. After the nurse fixes the patient, the Velcro is wrapped around the first tightening belt for one week to make the Velcro fur surface stick to the Velcro hook surface, so as to prevent the excess second tightening belt from being dragged inside the device during use, affecting the patient's exercise on the device.

[0016] Preferably, a support frame is fixedly connected to the inner wall of the device body, and an anti-slip sleeve is provided on the outer wall of the support frame. The provision of the support frame can provide more force points for the patient, and the patient's weight can be effectively dispersed when the patient holds the support frame, thereby reducing part of the pressure on the legs caused by the patient's own weight. At the same time, it can also reduce the damage caused by the patient's weight to the first tightening belt and the second tightening belt, thereby extending the service life of the device.
