Description

Technical Field

[0001] The utility model relates to the technical field of knee joint rehabilitation training, in particular to a knee joint rehabilitation training assistant. Background Art

[0002] The knee joint is the largest, most complex and most vulnerable joint in the human body. People who engage in heavy physical labor and intense jumping exercises for a long time are prone to knee joint injuries. Knee joint rehabilitation training aids are equipment or tools that help individuals rehabilitate their knee joints and are more common in medical rehabilitation training.

[0003] Existing technologies include a utility model with a publication number of CN207071199U. This patent discloses a postoperative rehabilitation device for knee joints, which includes a thigh auxiliary part and a calf auxiliary part interconnected by a connecting joint. The thigh auxiliary part and the calf auxiliary part respectively include two parallel telescopic rods and a protective part wrapped around the two telescopic rods. The protective parts of the thigh auxiliary part and the calf auxiliary part are wrapped around the thigh and the calf respectively; the connecting joint is composed of two connecting joints and an angle adjuster that are symmetrically arranged on the left and right. The lower parts of the two telescopic rods of the thigh auxiliary part and the upper parts of the two telescopic rods of the calf auxiliary part are respectively connected by two connecting joints, and rotate relative to each other along the position of the connecting joints. The rotation angle is adjusted and locked by the angle adjuster. The telescopic rod of the postoperative rehabilitation device for knee joints of this utility model can avoid the longitudinal pulling of the thigh and calf auxiliary parts on the legs caused by the extension and contraction of the calf during the patient's rehabilitation training, thereby preventing the patient from being injured again during exercise.

[0004] In medical rehabilitation training, it is found that during the patient's knee joint rehabilitation training, medical staff usually need to use rehabilitation equipment to assist in protecting the patient's legs. Since the knee joints of different patients are of different sizes, and the usual rehabilitation training equipment is relatively cumbersome to adjust, it is inconvenient to squeeze and limit the patient's knee joints. For this reason, we propose a knee joint rehabilitation training aid. Utility Model Content

[0013] The effect achieved by the above components is that when the first fixing belt and the second fixing belt are fixed in a limited position, the Velcro and the Velcro can be used to better fix them, thereby preventing the first fixing belt and the second fixing belt from falling off.

[0014] In some embodiments, a plurality of ventilation holes are opened on the surface of the protective frame, and the plurality of ventilation holes are evenly distributed on the surface of the protective frame.

[0015] The effect achieved by the above components is that when the protective frame and the patient's leg joint are squeezed and limited, auxiliary ventilation can be achieved with the help of the ventilation holes opened on the surface of the protective frame.

[0016] In some embodiments, positioning frames are fixedly connected to both sides of the surface of the lower joint frame, an auxiliary plate is abutted against the inner wall of the bottom end of the lower joint frame corresponding to the position of the positioning frame, a plurality of protrusions are fixedly connected to the surface of the auxiliary plate, and the plurality of protrusions are silicone blocks, and the auxiliary plate is fixedly connected to the position of the positioning frame, the cross-section of the positioning plate is in the shape of a barb, and the surface of the positioning plate is clamped with the inner wall of the positioning frame.

[0017] The effect achieved by the above components is: in the process of protecting and supporting the lower joint frame, in order to avoid excessive collision between the bottom end of the lower joint frame and the patient's leg joints, an auxiliary plate can be used for protection, and the hook-shaped positioning plate and the positioning frame can be clamped and limited, and then pressed with the help of silicone protrusions for protection.

[0018] In some embodiments, the positioning plate is a hard alloy plate, and the cross-sectional dimensions of the positioning plate are adapted to the cross-sectional dimensions of the positioning frame.

[0019] The effect achieved by the above components is that the positioning plate made of cemented carbide can be used for a long time, and extrusion deformation between the positioning plate and the positioning frame is avoided.
