[0037] As a technical optimization solution of the utility model, two symmetrically arranged annular straps 7 are horizontally provided in the middle of the walking support 3, and the two annular straps 7 are used to bind to the patient's legs respectively. Two straight rods 8 are slidably provided on the left and right sides of the walking support 3, and the straight rods 8 can be fixed to the walking support 3 by a tightening knob, that is, one end of the straight rod 8 is penetrated by a tightening knob that abuts against the walking support 3. The two annular straps 7 are connected by a belt rope, and the two annular straps 7 are detachably fixedly connected to the two straight rods 8 by elastic retractable belts, that is, the two annular straps 7 can also be disassembled and removed. The two straight rods 8 can move up and down, and the height of the two annular straps 7 can be adjusted to meet the binding requirements of the legs of different patients.

[0038] As a technical optimization solution of the utility model, a bottom plate 9 is provided at the bottom of the support column 5, and two screws 10 are provided through the bottom plate 9, and the two screws 10 can be threadedly connected with the top of the telescopic column 2, and the two screws 10 are used to fix the support column 5. That is, the top of the telescopic column 2 is provided with threaded holes corresponding to the two screws 10, and after the two screws 10 are aligned and screwed into the threaded holes, the support column 5 can be fixed, that is, the rotation of the support column 5 is restricted.

[0039] As a technical optimization solution of the utility model, the end of the cushion plate 4 close to the retractable column 2 is detachably fixed with an inclined plate 11, and the inclined plate 11 is provided with two wavy grooves. When the patient sits on the cushion plate 4, the legs can be placed on the two wavy grooves of the two inclined plates 11 and are stably restrained by them to ensure a stable sitting posture. The end of the cushion plate 4 away from the inclined plate 11 is hinged with a backrest plate 12, and the backrest plate 12 can be arranged horizontally aligned with the cushion plate 4 or arranged vertically correspondingly. When the backrest plate 12 is arranged vertically, it is convenient for the patient to sit on the cushion plate 4 for back support.

[0040] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, when the backrest plate 12 is horizontally aligned or vertical with the seat plate 4, it can be fixed by correspondingly setting bolts, that is, maintaining the state where the backrest plate 12 is horizontally aligned or vertical with the seat plate 4.

[0041] As a technical optimization solution of the present utility model, the driving and adjusting mechanism includes two rotating rods 13. The two rotating rods 13 are respectively parallel to the two support columns 5, and the lower ends of the two rotating rods 13 are respectively rotatably connected to the two support columns 5. A plurality of arc-shaped support rods 14 are fixed to the upper ends of the two rotating rods 13. A slot that is inserted and matched with the plurality of arc-shaped support rods 14 is provided at the bottom of the seat plate 4. Power take-up reels 16 are provided at the tops of the two support columns 5, and ropes 17 are wound on the power take-up reels 16. One ends of the two ropes 17 are respectively fixedly connected to the two rotating rods 13. Baffles 15 are fixed to the sides of the two rotating rods 13, and the support columns 5 are provided with notches corresponding to the baffles 15. The baffles 15 can play the role of protecting and restricting the position of the patient. The two rotating rods 13 can be controlled to rotate by the corresponding ropes 17 by the power take-up reels 16. When the two rotating rods 13 are horizontally arranged, after the plurality of arc-shaped support rods 14 of the two rotating rods 13 are inserted into the slots at the bottom of the seat plate 4, the rotation of the two rotating rods 13 can drive the seat plate 4 to rotate and move synchronously. When the seat plate 4 is horizontally arranged, it is used to match the bed surface of the existing hospital bed 18.

[0042] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, the power take-up reel 16 is the motor control reel. The rope 17 is fixed and wound on the reel, and the motor can accurately control the rotation of the reel. The rotation of the reel can realize the winding of the rope 17, thereby driving the rotating rod 13 to rotate.

[0043] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, it is not limited to setting the power take-up reel 16 to perform the winding operation of the rope 17, and a crank can also be set to manually wind the reel to perform the winding operation of the rope 17.

[0044] In the present utility model, the working principle of the device is as follows:

[0045] During operation, the device can be first set to the side of the hospital bed 18. The two telescopic columns 2 can be adjusted to an appropriate height in advance so that the bottom of the seat plate 4 is slightly higher than the mattress, and the seat plate 4 is set at the bedside position. Then, rotate the support column 5 on the side corresponding to the patient. The support column 5 can rotate around the center of the top of the telescopic column 2. At this time, the corresponding rotating rod 13 and the baffle 15 also rotate to one side. At this time, the seat plate 4 is located at the bedside position, and a space is left on its side due to the rotation of the corresponding support column 5. Medical staff can help the patient sit on the seat plate 4, and the legs can be placed on the two wavy grooves of the two inclined plates 11, thus stabilizing the patient's sitting posture. Then, the two annular straps 7 can be removed first and respectively tied to the patient's legs. At this time, rotate the just-rotated support column 5 back to its original position, and fix the support column 5 to the telescopic column 2 with the corresponding two screw rods 10. When the support column 5 is reset, a number of arc-shaped support rods 14 are inserted into the slots at the bottom of the seat plate 4. At this time, a number of arc-shaped support rods 14 of the two rotating rods 13 are inserted into the slots at the bottom of the seat plate 4, and the two support columns 5 are fixedly arranged and keep the rotating rod 13 stable. Then, start the two power take-up reels 16 at the same time. The two ropes 17 are wound synchronously and drive the two rotating rods 13. At this time, the two rotating rods 13 drive the seat plate 4 to rotate and move synchronously. The rotation direction of the seat plate 4 is from the horizontal state to the vertical state. During this process, the backrest plate 12 is horizontally aligned with the seat plate 4. The process of the seat plate 4 rotating from the horizontal state to the vertical state is a gentle process, which can gradually lift the patient and assist the patient to gradually change from the sitting state to the standing state. After the patient is in the standing state, install the two annular straps 7 between the two straight rods 8. At this time, the patient stands between the bottom moving frames 1 and can hold the walking aid bracket 3 with the hand to perform the walking aid operation. And the process of the seat plate 4 slowly lifting the patient conforms to the process of the patient getting out of bed and moving gradually, that is, from the lying position to the sitting position and then to the upright position, effectively preventing orthostatic hypotension.

[0046] As can be seen from the above steps, the device can assist the patient to stand up, eliminating the process of the medical staff assisting the patient from standing up from the bed to walking aid, that is, there is no need for the medical staff to help the patient stand up and support the patient to walk to the walking aid cart, effectively reducing the workload of the medical staff. And relevant equipment such as infusion pumps and oxygen cylinders can be fixedly installed on the walking aid bracket in advance, effectively improving the efficiency of the walking aid operation.

[0047] At the same time, when the device is used for walking aid, the seat plate 4 can be laid flat, and the backrest plate 12 and the seat plate 4 are set to be perpendicular to each other, which is convenient for the patient to sit down and rest at any time when they are out of strength during the walking process. And with the cooperation of the two baffles 15, it can play the role of protecting and restricting the patient's body position. And during the walking process, when the seat plate 4 is in the vertical state, the seat plate 4 can play the role of protecting the back and restricting the patient's body position.

[0048] Moreover, when in use, the upper end of the walking aid bracket 3 can be adjusted in telescopic height according to requirements, meeting the diverse height usage needs of patients. Also, the two straight rods 8 can move up and down to adjust the height of the two annular straps 7 to adapt to the binding requirements of different patients' legs and facilitate removal from below. The two annular straps 7 can effectively stabilize the patient's legs and play an auxiliary stabilizing effect.

[0049] Meanwhile, several mounting struts 6 can install and fix a wire mesh frame or a related frame body, which can be used to fixedly place a ventilator and an oxygen cylinder, facilitating patients to inhale oxygen or move around with a ventilator. Patients don't need to carry them on their own bodies, reducing the burden during activities. Several mounting struts 6 can install and fix the frame for an infusion pump or an injection pump, ensuring the safety of medication when patients are moving. Several mounting struts 6 can fix the rope buckles for various pipelines, avoiding the situation of accidental pulling and tube disconnection caused by too many unfixed pipelines.

[0050] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
