Embodiment 1

[0027] like Figure 1-6As shown, a bedside knee joint range of motion training device includes a bracket 1, and the bracket 1 is provided with a bottom plate 2 below. There are two sets of legs on the lower surface of the bottom plate 2, two in each group, symmetrically arranged on both sides of the bottom plate 2, and the legs are rotated to open when in use to enhance the stability of the entire device; they can be rotated and stored on the bottom plate when not in use 2, to save storage space; the bottom plate 2 is provided with a circular groove, and one end of the groove is hinged with a first support plate 3 that matches the groove. When the device is not in use, the first support plate can be 3 is received in the groove to save storage space; the first support plate 3 is provided with a first chute 4 in the middle of the lower bottom surface, and the first chute 4 is provided with a slidingly connected first slider 5, the first slider 5 is connected with the upper surf...

Embodiment 2

[0029] The working method of a bedside knee joint range of motion training device is as follows: when the patient needs to exercise, move the device to the hospital bed, rotate and open the outrigger under the bottom plate 2, and place the patient's thigh on the knee joint replacement side On the first support plate 3, put the shank on the second support plate 9, and fix the thigh and the shank respectively with elastic cords and fixed cards, then start the stepping motor 20, drive the lifting device 11 to move upward, and the lifting device 11 drives Telescopic rod 10 and the second support plate 9, the first support plate 3 move upwards until the lifting device 11 drives the pointer 27 above the connecting plate 18 to indicate the 0 ° value on the scale 27, stop the stepper motor 20 work, this time the thigh . The block 5 is fixed in the limit hole 7 to ensure the stability of the first support plate 3; according to the patient's postoperative rehabilitation situation and th...

Embodiment 3

[0031] A bedside knee joint range of motion training device can also be used for exercise during the middle and late rehabilitation of patients. In the middle and later stages of the patient's rehabilitation, the replaced knee joint has high stability, and the patient's muscle strength and ligament strength have also been greatly restored. At this time, the knee joint can be actively moved according to its own strength. Training; when using the device, first disconnect the telescopic rod 10 from the lifting device 11, put some devices such as the base plate 2, the first support plate 3, and the second support plate 9 on the sickbed, and rotate to open the bottom plate 2. Outriggers ensure the stability of the device; put the thighs into the first support plate 3 and fix them with elastic cords and fixed clips, put the lower legs into the second support plate 9 and fix them with elastic cords and fixed clips, and then lift The second support plate 9 and the shank drive the firs...

Abstract

The invention discloses a bedside knee joint motion range training device. The bedside knee joint motion range training device comprises a bracket and a groove; the groove is connected with a first supporting plate; a first chute, a first sliding block and a supporting rod are arranged on the bottom surface of the first supporting plate; the first supporting plate is connected with a second supporting plate; the end part of the second supporting plate is movably connected with a telescopic rod; the telescopic rod is connected with a lifting device; the lifting device comprises an upright, a second chute, a second sliding block and a screw rod transmission mechanism; the screw rod transmission mechanism drives the telescopic rod and the second supporting plate to move up and down; a third sliding block and a fourth sliding block are arranged in the second chute; the third sliding block is connected with an upper limiting switch; the fourth sliding block is connected with a lower limiting switch; the upright is provided with a scale; and a pointer is arranged at one side of the scale. The device can provide passive exercise and active exercise for a knee joint motion range, is convenient to observe a value of the joint motion range in real time, accurately controls a knee joint exercise angle and implements bedside knee joint motion range exercise.

Description

technical field [0001] The invention relates to the field of knee joint rehabilitation devices, in particular to a bedside knee joint activity training device. Background technique [0002] With the intensification of the aging process, more and more elderly people are facing orthopedic diseases, among which knee degenerative osteoarthritis is a common disease of the elderly, such as knee joint arthritis, rheumatoid arthritis, etc. Serious diseases, because the knee joint is an important weight-bearing joint of the lower limbs, its structure and function are the most complex among human joints, directly affecting the normal quality of life, causing great pain to patients, so more and more patients need artificial knee replacement many. Through knee replacement, the artificial knee joint with bionic performance can be used to replace the damaged knee joint, which can relieve knee joint pain, improve knee joint function, correct knee joint deformity and obtain long-term stabi...
