Description
Technical Field
[0001] The utility model relates to the technical field of lower limb rehabilitation training devices, in particular to a lower limb rehabilitation training device for patients with cerebral infarction. Background Art
[0002] In the rehabilitation department of traditional Chinese medicine, the lower limbs of patients with cerebral infarction are generally unable to move on their own. Therefore, in order to help patients recover better, lower limb rehabilitation trainers are used to assist patients in training and recovery, and help patients recover limb functions as soon as possible. For example, in the patent number "CN219721830U" and the patent name "A lower limb rehabilitation trainer", the two support columns under the top cover are rotated to both sides and unfolded, and the connecting rods in the storage grooves on the inner sides of the two support columns are rotated and opened. As the two support columns are continuously unfolded, the distance between the bottoms of the two connecting rods continues to increase. When one of the connecting rod ends When the hook part of the upper part is just inserted into the outer wall of the limiting rod in the concave groove at the top of the other connecting rod, the two connecting rods are connected, and the expansion of the two support columns is limited, so that the two support columns are placed in an eight-shaped shape, and the concave seat and the anti-skid pad are in contact with the ground to keep the support columns and the top cover stable. Then, the connecting cover at the bottom of the flywheel training mechanism is put on the positioning block at the top of the top cover for positioning, and finally the locking bolts are used to lock and fix the two, so that the overall assembly can be quickly completed, which is convenient for carrying or storage. However, the above structure still has the following problems in actual use:
[0003] When patients use the above-mentioned rehabilitation device for training, long-term exercise can easily make the patient's leg muscles tense, so the leg muscles need to be relaxed manually. If they are not relaxed for a long time, it is easy to affect the patient's recovery, resulting in poor recovery effect and poor practicality.
[0004] Therefore, we proposed that the lower limb rehabilitation training device for patients with cerebral infarction can solve the above problems well. Utility Model Content
