Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an auxiliary device for elderly knee joint health care. Background Art

[0002] The knee joint is one of the largest and most complex joints in the human body, and its health has an important impact on the quality of life of the elderly. Knee joint diseases such as knee osteoarthritis and rheumatoid arthritis are particularly common among the elderly, so rehabilitation is needed; existing rehabilitation devices cannot improve the firmness of the installation of the protective cover, that is, they cannot prevent it from falling off when walking, and they cannot improve warmth by heating water without affecting normal walking.

[0003] A Chinese patent discloses a knee joint protector suitable for rheumatoid arthritis (authorization announcement number CN217611667U). This patented technology locks the anti-slip belt in the anti-slip component to the connecting sleeve through a connecting bolt, thereby fixing the anti-slip ring and the sleeve body together. Then, the limiting rope is tightened and its two ends are tied together to fix the anti-slip ring to the leg, which can prevent the sleeve body from falling off when the user walks. The first pipe cover in the warming component is removed and hot water is added to the warming bag through the water inlet pipe and the first pipe cover is tightened. In this way, the heat generated by the hot water in the warming bag can effectively warm the user's knees, thereby improving the warming effect and not affecting the user's free movement.

[0004] However, it has certain disadvantages: the warming bag is fixed to the warming pad by a mounting rod, a mounting block, and a mounting nut. Therefore, when the water in the warming bag needs to be replaced, if it is not removed and added directly, the splashing hot water may easily scald the user. If it is disassembled, the entire protective cover needs to be removed first, and then the mounting nut is loosened to remove the warming bag. The operation is complicated, time-consuming and labor-intensive, and the hot water in the warming bag cannot be replaced quickly. Utility Model Content
