DETAILED DESCRIPTION

[0020] The present invention is described below with specific embodiments, but is not intended to be a limitation of the present invention.

[0021] Example 1

[0022] like Figure 1-Figure 3As shown, in this embodiment, a support for knee joint function training is provided, comprising a bottom plate 1, a thigh support plate 2 and a calf support plate 3, one end of the thigh support plate 2 is hinged to one end of the bottom plate 1, and the end of the thigh support plate 2 away from the bottom plate 1 is hinged to one end of the calf support plate 3, and two drawstrings 5 ​​are symmetrically arranged on both sides of one end of the thigh support plate 2 close to the calf support plate 3, and handles 6 are sleeved on the two drawstrings 5;

[0023] Among them, a plurality of pulleys 4 are fixedly arranged at one end of the calf support plate 3 away from the thigh support plate 2, and the plurality of pulleys 4 are rollingly connected to the upper surface of the bottom plate 1, and the pulley 4 includes a ball seat and a rolling ball, and the ball seat is fixed to the lower surface of the calf support plate 3, and the rolling ball is in contact with the upper surface of the bottom plate 1. When the calf support plate 3 is subjected to force, the rolling ball rolls on the upper surface of the bottom plate 1, so as to adjust the angle of the calf support plate 3;

[0024] The bottom plate 1 is placed on the bed, and then the patient's affected limb is placed on the thigh support plate 2 and the calf support plate 3. At this time, the thigh support plate 2 supports the patient's thigh, and the calf support plate 3 supports the patient's calf, and the knee joint is located at the hinge of the thigh support plate 2 and the calf support plate 3;

[0025] Active flexion and extension exercise of the knee joint: the end of the calf support plate 3 away from the thigh support plate 2 slides on the bottom plate 1 through the pulley 4, and the patient's affected limb actively drives the end of the calf support plate 3 away from the thigh support plate 2 to slide on the bottom plate 1, at this time, the thigh support plate 2 and the calf support plate 3 swing, and then the active flexion and extension exercise of the knee joint is realized;

[0026] Passive flexion and extension exercise of the knee joint: by pulling and releasing the handle 6, and coordinating the end of the calf support plate 3 away from the thigh support plate 2 to slide on the bottom plate 1 through the pulley 4, the pull belt 5 can drive the thigh support plate 2 and the calf support plate 3 to swing, thereby realizing the passive flexion and extension exercise of the knee joint.

[0027] According to the individualized treatment plan, the above-mentioned active and passive flexion and extension exercises of the knee joint are performed to effectively exercise the muscles and ligaments around the knee joint and achieve the goal of early exercise and early recovery;

[0028] Effectively promote blood circulation in the lower limbs, prevent the risk of lower limb venous thrombosis, avoid adhesion of joint tendons, and avoid atrophy of lower limb muscle groups.

[0029] like Figure 1 , Figure 2 As shown, in order to facilitate the fixation of the patient's affected limb on the thigh support plate 2 and the calf support plate 3, a plurality of connecting rings 7 are fixedly connected to the lower surface of the calf support plate 3, and a strap 8 for tying the patient's calf to the calf support plate 3 is connected inside the connecting ring 7, and the two ends of the strap 8 are fixed by Velcro. Figure 1As shown, after the Velcro at both ends of the strap 8 is torn off, the strap 8 is in an open state, and then the patient's affected limb is overlapped on the thigh support plate 2 and the calf support plate 3, and then the Velcro is used to stick the two ends of the strap 8, so that the strap 8 fixes the patient's affected limb on the thigh support plate 2 and the calf support plate 3 to improve the stability during knee joint exercise.

[0030] In order to increase the comfort of the patient during knee joint function training, a layer of leather pad is laid on the upper surface of the thigh support plate 2 and the calf support plate 3.

[0031] Example 2

[0032] like Figure 1-Figure 3 As shown, on the basis of Example 1, in order to be able to control the angle of knee joint movement according to an individualized treatment plan, two limiting components 9 are symmetrically arranged on both sides of the base plate 1, and the limiting component 9 includes a U-shaped block 901, and the U-shaped block 901 is clamped on the side wall of the base plate 1. The upper side of the U-shaped block 901 is meshed and connected with a bolt rod 902, and the threaded end of the bolt rod 902 penetrates the side wall of the U-shaped block 901 and is connected with a top block 903. When the bolt rod 902 is screwed in and twisted, the top block 903 The top is pressed on the upper surface of the bottom plate 1. At this time, the cooperation between the U-shaped block 1 901 and the top block 903 can clamp the bottom plate 1. When the patient's affected limb extends the knee joint, the end of the calf support plate 3 away from the thigh support plate 2 moves toward the limit assembly 9. When the end of the calf support plate 3 away from the thigh support plate 2 abuts against the bolt rod 902, the angle of the knee joint movement is controlled. When the bolt rod 902 is loosened, the U-shaped block 901 can move on the side wall of the bottom plate 1, thereby adjusting the range of the knee joint movement angle, which is suitable for a variety of individualized treatment plans.

[0033] In addition, a limit assembly 9 is additionally provided on both sides of the base plate 1 and below the calf support plate 3, that is, two limit assemblies 9 are provided on each side of the base plate 1. When one end of the calf support plate 3 away from the thigh support plate 2 abuts against the bolt rod 902, the bolt rod 902 on the limit assembly 9 below the calf support plate 3 can support the calf support plate 3, thereby increasing the stability of the calf support plate 3.

[0034] like Figure 3 As shown, in order to further increase the stability of the U-shaped block 901 clamping the side wall of the bottom plate 1, anti-slip lines are provided on the inner side wall of the U-shaped block 901.

[0035] like Figure 1 As shown, in order to facilitate the acquisition of the knee joint bending angle, an angle identification card 10 is fixedly adhered to the upper surface of the base plate 1.

[0036] Example 3

[0037] like Figure 4-Figure 6The U-shaped block 11 is detachably clamped on the calf support plate 3 in the form of an interference fit, and a pin 12 is inserted into each U-shaped block 11, and a plurality of rows of slots 13 are provided on the side wall of the bottom plate 1, and a plurality of pins 12 correspond to the plurality of rows of slots 13 one by one, and the pins 12 are movably inserted into the slots 13. When the pins 12 are inserted into the slots 13 at different positions, the angles of the thigh support plate 2 and the calf support plate 3 can be adjusted, and the cooperation between the pins 12 and the slots 13 can fix the adjusted angles of the thigh support plate 2 and the calf support plate 3, thereby maintaining different degrees of flexion of the patient's hip and knee joints, and the U-shaped block 11 is flexible to assemble and disassemble, and convenient to use.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
