[0022] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0023] Referring to Figure 1 The present application provides a special wheelchair for lower limb fracture patients, comprising a wheelchair 1, the structure of the wheelchair 1 is the same as that of a conventional wheelchair, which comprises a cushion 2, side wheels 3 supported on both sides of the cushion 2, armrests 4 provided on both sides of the cushion 2, and footrests 5 connected to the armrests 4. The footrests 5 are adjustable height footrests, further comprising: a brace 6 mounted on the footrests 5, the brace 6 comprising a leg support 7, an adjustable support device 8 connected to the leg support 7, and a mounting seat 9. The adjustable height footrest is a prior art, specifically, the adjustable height footrest is described in detail in the invention of the adjustable height wheelchair footrest with publication number CN109953857A, which is a known prior art. Therefore, no further description is given. The adjustable height footrest can realize stepless adjustment of the lifting height of the footrest, providing great convenience and comfort to the user. A shock absorbing rod 8 is provided at the side wheels 3 for overall shock absorption of the wheelchair 1.

[0024] The leg support 7 is a U-shaped plate, the leg support 7 is made of a deformable material, and a sponge shock absorbing layer is laid in the inner layer of the leg support 7. Specifically, the edge corners of the leg support 7 are provided as rounded corners, the upper surface of the leg support 7 is provided with a soft pad, the leg of a patient fixed by the brace 6 or plaster is placed in the leg support 7, and the leg support 7 can be an expansion plate which can be adjusted in length.

[0025] Referring to Figures 2-5 The adjustable support device 8 comprises a screw rod mounted below the leg support 7, a fixed plate 14 provided below the screw rod, and a support rod 15 provided below the fixed plate 14. The screw rod comprises a first screw rod 10, a second screw rod 11, a third screw rod 12, and a fourth screw rod 13. The upper end of the screw rod is connected to the leg support 7 through a spherical hinge 16, and the lower end penetrates through the fixed plate 14 and is threadedly connected to the fixed plate 14.

[0026] The support rod 15 comprises a telescopic rod and a damping rod 8, and the telescopic rod is coaxially arranged with the damping rod 8. The support rod 15 has telescopic function and damping function.

[0027] The first screw rod 10 and the second screw rod 11 are arranged along the length direction of the leg support 7, and the upper ends of the first screw rod 10 and the second screw rod 11 are respectively hinged to the side walls of the leg support 7. The first screw rod 10 and the second screw rod 11 are used for adjusting the opening degree of the leg support 7 to adapt to people of different body types. Rotating the first screw rod 10 or the second screw rod 11 can make the screw rod body move upward or downward, drive the U-shaped plate side wall of the leg support 7 to open or tighten, and match the legs of patients of different body types.

[0028] The third screw rod 12 and the fourth screw rod 13 are symmetrically arranged on both sides of the leg support 7 and staggered with the first screw rod 10 and the second screw rod 11. The leg support 7 is connected with the fixed plate 14 through the screw rod, and the third screw rod 12 and the fourth screw rod 13 are used for adjusting the inclination angle of the leg support 7. Rotating the third screw rod 12 or the fourth screw rod 13 can change the position of the third screw rod 12 or the fourth screw rod 13, adjust the height difference of the upper ends of the two screw rods, and adjust the inclination degree of the leg support 7. The flat leg position does not conform to ergonomics, which can cause discomfort to patients; adjusting the inclination degree of the leg support 7 can make the patient's leg slightly inclined naturally, thereby improving comfort.

[0029] The bottom of the support rod 15 is provided with the first sliding block 17, the rod body of the support rod 15 is provided with the supporting leg 18, and the distal end of the supporting leg 18 is rotatably connected with the roller 19. The supporting leg 18 is used for assisting the support rod 15 and enhancing stability.

[0030] The mounting seat 9 comprises the first sliding groove 20 and the clamping piece arranged at the bottom of the first sliding groove 20. The first sliding block 17 is slidably connected in the first sliding groove 20, and the upper surface of the first sliding groove 20 has a groove 23 facilitating the movement of the supporting leg 18. The first sliding block 17 of the support rod 15 is embedded in the first sliding groove 20 of the mounting seat 9, and the first sliding block 17 slides in the first sliding groove 20. The contact surface between the first sliding block 17 and the first sliding groove 20 is rough, so that the first sliding block 17 cannot be pushed to move when the leg support 7 contains the injured leg of the patient. Before placing the injured leg of the patient, the support rod 15 is pushed to move in the first sliding groove 20, so as to match the leg position of the patient or adjust the position of the support rod 15 after placing the injured leg of the patient for a period of time, thereby avoiding muscle fatigue of the leg root caused by long-time staying in one position.

[0031] The clamping piece comprises a U-shaped frame 21 and a bolt 22 threadedly connected with the U-shaped frame 21. The U-shaped frame 21 is transversely arranged, and the bolt 22 is perpendicular to the side wall of the U-shaped frame 21. The U-shaped frame 21 transversely wraps the footrest 5, and the bolt 22 is rotated to abut against the footrest 5, so as to complete the fixing.

[0032] The fixed plate 14 is provided with a second sliding groove 24 near the side of the wheelchair 1, the second sliding groove 24 is embedded with a second sliding block 25, the second sliding block 25 is fixedly connected with a pull rope 26, the pull rope 26 is fixedly connected with a hook 27 at the end, the hook 27 is a cylindrical shape, the hook is movably connected with the wheelchair, and is used for stabilizing the brace 6.

[0033] The use process is as follows: first, let the patient sit on the wheelchair 1, install the seat 9 to be connected with the foot pedal 5, place the injured leg of the patient in the leg support 7, adjust the position of the support rod 15 according to the shape of the patient, change the height of the first screw rod 10 and the second screw rod 11 to adjust the opening degree of the leg support 7, change the height of the third screw rod 12 and the fourth screw rod 13 to fine-tune the inclination angle of the leg support 7, so that the injured leg of the patient is located in a basically horizontal and comfortable position; after sitting on the wheelchair 1 for a period of time, slightly adjust the position of the support rod 15 and the inclination angle of the leg support 7, change the placement position of the injured leg of the patient, and relieve the muscle fatigue of the leg root.

[0034] Although the above-mentioned embodiments have been shown and described, it can be understood that the above-mentioned embodiments are exemplary and cannot be understood as limiting the utility model, and the changes, modifications, replacements and modifications of the above-mentioned embodiments made by the ordinary skilled in the art are within the protection scope of the utility model.
