Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation instruments, and particularly to a knee joint rehabilitation instrument. Background Art

[0002] The knee joint is the largest and most complex joint in the human body. It connects the femur, tibia and patella, and is responsible for supporting the body weight and allowing the leg to perform various movements such as flexion, extension, internal rotation and external rotation. With the increase of age and the influence of external trauma on the knee joint, it is prone to injury and lesion, affecting normal functions and daily activity abilities. Therefore, knee joint rehabilitation treatment is needed.

[0003] Traditional knee joint rehabilitation methods mainly include physical therapy, exercise therapy and drug therapy, etc. Physical therapy is usually carried out by professional rehabilitation therapists for manipulative massage, heat therapy, electrotherapy and other operations. However, this method depends on the experience and time of the rehabilitation therapist. Patients often need to frequently go to medical institutions, which is not only time-consuming and laborious, but also has a high treatment cost. Exercise therapy requires patients to perform specific rehabilitation training actions under the guidance of a rehabilitation therapist. However, due to the lack of effective supervision and feedback mechanisms, when patients train at home by themselves, it is easy to have problems such as non-standard movements, insufficient or excessive training intensity, affecting the rehabilitation effect. Although drug therapy can relieve pain and inflammation to a certain extent, its effect on the recovery of knee joint function is limited, and it is inconvenient to move after applying the drug. In addition, long-term use of drugs may bring some side effects.

[0004] With the increasing market demand, knee joint rehabilitation instruments have emerged. Currently, the most commonly used knee joint rehabilitation instruments on the market have relatively single functions and usually only can perform simple massage treatment. In addition, the operation of another part of the rehabilitation instruments is complex, the price is expensive, it is not convenient for patients to use by themselves, and it cannot be flexibly adjusted according to the specific condition and rehabilitation progress of patients, and the rehabilitation effect is not obvious. Summary of the Invention

[0005] The purpose of the present invention is to provide a knee joint rehabilitation instrument to solve the technical problems existing in the prior art.

[0006] In order to achieve the above-mentioned invention purpose, the technical solution adopted by the present invention is as follows:

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention combines the functions of knee joint massage, rehabilitation liquid spraying, and hot compress through the settings of a massage component, a liquid medicine spraying component, and a hot compress component. By massaging, the muscle tissues around the knee joint are relaxed, thus relieving knee joint pain. While massaging, the rehabilitation liquid is sprayed onto the knee joint, improving the absorption efficiency of the rehabilitation liquid. Through the hot compress component, the surrounding skin tissues are hot compressed, expanding the surrounding blood vessels and increasing the blood circulation volume, thereby providing a comprehensive and all-round rehabilitation plan for the user. The rehabilitation effect on the knee joint is remarkable. When the invention is used, it can be fixed to the knee by a fixing strap, and the invention is started by activating the control terminal. The operation is simple, time-saving and labor-saving, and the treatment cost is low. BRIEF DESCRIPTION OF THE DRAWINGS
