Description

Technical Field

[0001] This utility model relates to the field of rehabilitation training assistance, specifically to a knee joint rehabilitation training assistance device. Background Technology

[0002] Knee joint rehabilitation training aids are devices specifically designed to assist patients with knee injuries or post-operative rehabilitation training. These devices aim to strengthen the muscles around the joint, improve joint stability, restore range of motion, and reduce pain. Below are some common knee joint rehabilitation training aids. A Chinese patent discloses a knee joint rehabilitation training aid (authorization announcement number CN 221888673U). This patented technology allows the aid to fold when not in use via a bottom connecting rod and an upper connecting rod, reducing space occupation. During normal use, a restraint rod restricts the position of the bottom and upper connecting rods, ensuring the stability of the support and enabling normal use of the aid. However, this design requires patients to perform standing rehabilitation training. Prolonged standing rehabilitation training is detrimental to the maintenance of the patient's knee joint and poses certain safety risks. Furthermore, standing rehabilitation training consumes excessive physical strength and energy. Therefore, those skilled in the art have provided a knee joint rehabilitation training aid to address the problems mentioned in the background art. Utility Model Content

[0005] Preferably, the connecting rod is fixedly installed on the side wall of the connecting arm, the connecting arm is connected to and installed with the lower leg sleeve, and a second fixing strap is installed on the lower leg sleeve;

[0006] Preferably: a fixing plate is installed on the outer wall of the connecting arm, a rotating plate is connected to the fixing plate, the rotating plate is installed in the rotating groove, and the rotating groove is located at the lower end of the inner side of the knee joint connecting handle.

[0007] Preferably, the upper inner side of the knee joint connecting handle is provided with a second rotating groove, a second rotating plate is installed in the second rotating groove, a second fixing plate is installed on the second rotating plate, the second fixing plate is installed in the groove, the groove is located in the ear plate, the ear plate is installed on the side wall of the thigh sleeve, two first fixing straps are installed on the thigh sleeve, and a knee joint protection strap is installed between the knee joint connecting handles.

[0008] The technical effects and advantages of this utility model are as follows:

[0009] 1. A chair is provided, and the patient can sit on the chair and put the leg that needs to be rehabilitated into the thigh sleeve and the calf sleeve in turn. It can be fixed by the No. 1 fixation strap and the No. 2 fixation strap. The operation is simple and can be completed by one person. Moreover, the seated rehabilitation training reduces the physical exertion of the patient.

[0010] 2. Adjust the knee protection belt to the patient's knee joint to further protect the knee joint. Slowly start the hydraulic cylinder, and the piston rod pushes the push plate, causing the connecting arm to move forward, which allows the patient's lower leg to extend forward. Repeat the back-and-forth training exercise to rehabilitate the knee joint. The operation is simple and safe. Patients can perform rehabilitation training in multiple groups and reasonably plan the training time. Attached Figure Description
