It is also the joint with the highest chance of injury. It is a pulley joint. The knee joint is directly under pressure when the human body walks or stands. The knee joint will suffer certain injuries when facing obese people, people who work or exercise at high intensity, etc. Therefore, a certain degree of care for the knee joint is also required during the treatment and rehabilitation stage of knee injury.
[0003] The Chinese utility model (CN218420350U) discloses an orthopedic knee joint care mobilizer. Through the cooperation of a motor, a turntable, a guide column, a rotating rod and a mounting seat, a movable push plate can be driven to push the patient's knee to move, thereby achieving the effect of nursing training. At the same time, the position of the guide column can be adjusted to adjust the swing amplitude of the movable push plate to meet the needs of different patients. However, when the patient uses the device, he or she also needs to be specially moved to a seat, which brings great inconvenience to patients with damaged knee joints who are unable to walk or stand. In view of the existing problems, a knee joint care mobilizer is proposed. Utility Model Content

DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] Example 1
[0023] Reference Figure 1-4 The knee joint care activity device comprises a first support plate 1 and a second support plate 2. The first support plate 1 and the second support plate 2 are both fixedly mounted with mounting seats 3 on both outer sides. The mounting seats 3 on the first support plate 1 and the second support plate 2 are both rotatably mounted with hinges 4 on their outer sides. Telescopic rods 5 are mounted on both sides of the first support plate 1 and the second support plate 2. The mounting seats 3 and the hinges 4 are arranged so that when the telescopic rod 5 is extended and retracted, that is, when the second support plate 2 is moved, it can adapt to the range of movement to ensure the normal operation of the device. The two ends of the telescopic rod 5 are respectively fixedly connected to the hinges 4 on both sides of the first support plate 1 and the second support plate 2. The first elastic belt 6 is respectively fixedly mounted on both ends of the first support plate 1, and the first elastic belt 6 plays a pre-tensioning role. To facilitate the connection of Velcro 10, the upper ends of the first elastic bands 6 at both ends are fixedly connected with the first splint 7, and the two ends of the second support plate 2 are respectively fixedly installed with the second elastic bands 8, and the outer ends of the second elastic bands 8 at both ends are fixedly installed with the second splint 9. By placing the first support plate 1 and the second support plate 2 respectively on the lower side of the thigh and the calf and setting them in contact with the skin, and at the same time, the first splint 7 and the second splint 9 are correspondingly sleeved on the thigh and the calf, limited fixation is achieved. At this time, it is only necessary to control the extension and retraction of the telescopic rod 5 to drive the calf to swing, and then perform nursing activities on the knee joint, so that the range of motion of the knee joint can be controlled, and additional damage to the knee joint caused by improper force of the patient's own activities can be avoided.
[0024] Anti-skid pads are fixedly laid on the inner walls of the first support plate 1, the second support plate 2, the first splint 7, and the second splint 9. The provision of the anti-skid pads can, on the one hand, increase the friction between the first support plate 1, the second support plate 2, the first splint 7, the second splint 9 and the skin; on the other hand, it can also optimize the user experience, that is, the provision of the anti-skid pads makes patients more comfortable when using it.
[0025] Corresponding grooves are provided on both sides of the first support plate 1, the second support plate 2, the first splint 7 and the second splint 9, and Velcro 10 is installed in the corresponding grooves. The Velcro 10 is divided into a hook side and a fleece side. The hook side is fixedly installed in the grooves on both sides of the first support plate 1 and the second support plate 2, and the fleece side is fixedly installed in the grooves on both sides of the first splint 7 and the second splint 9. At the same time, the use of Velcro 10 will ensure the stability of the connection between the first splint 7 and the first support plate 1, and between the second splint 9 and the second support plate 2, thereby ensuring the normal movement of the knee joint.
[0026] Example 2
[0027] According to Example 1, the purpose of knee joint care can be achieved by intermittently lifting the calf in Example 1. However, the effect of the care activity is limited. Figure 1-4 , as another preferred embodiment of the utility model, based on embodiment 1;
[0028] A knee tensioning belt 11 is installed between the first splint 7 and the second splint 9, and connecting belts 14 are fixedly installed in an array at both ends of the knee tensioning belt 11. The outer ends of the connecting belts 14 are fixedly connected to the first splint 7 and the second splint 9. A massager 12 is fixedly installed in an array on the knee tensioning belt 11. When knee joint care activities are performed, that is, when the second support plate 2 and the second splint 9 swing back and forth, due to the limiting traction of the connecting belt 14, the knee tensioning belt 11 can be intermittently tensioned and periodically tensioned to wrap the knee. At the same time, when the knee tensioning belt 11 tightly wraps the knee joint, the massager 12 massages the knee joint by its own vibration.
[0029] A gasket 13 is fixedly installed on the inner side of the knee tensioning belt 11 corresponding to the massager 12. The gasket 13 is used to isolate the massager 12 from direct contact with the skin, thereby improving the good experience and optimizing the effect of knee joint care activities.
[0030] Working principle: when in use, first control the extension of the telescopic rod 5 until the first support plate 1 and the second support plate 2 are horizontal, straighten the patient's leg, put the first support plate 1 and the first splint 7 through the foot, and pull them toward the thigh, then put the second support plate 2 and the second splint 9 from the foot, and pull them to the upper part of the calf. After pulling them to the predetermined position, tighten the fur surface of the Velcro 10 and attach it to the hook surface to achieve limited fixation. At this time, the wearing is completed, control the contraction of the telescopic rod 5, pull the second support plate 2 to drive the calf to bend downward until the calf is perpendicular to the thigh, and repeatedly control the extension and contraction of the telescopic rod 5, so as to achieve active exercise of the knee joint. When performing knee joint care activities, that is, when the second support plate 2 and the second splint 9 swing back and forth, due to the limited traction of the connecting belt 14, the knee tensioning belt 11 can be intermittently tensioned, and periodically tensioned to wrap the knee. At the same time, when the knee tensioning belt 11 tightly wraps the knee joint, the massager 12 relies on its own vibration to massage the knee joint.
[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
