Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a constant temperature rotating anti-foot drop device. Background Technology

[0002] Foot rehabilitation training is an important measure to restore foot function, reduce pain, and prevent further injury. Foot rehabilitation training needs to be based on individual conditions to develop personalized plans and combine basic rehabilitation training, targeted rehabilitation training, lifestyle adjustments, and other precautions for comprehensive treatment.

[0003] In existing technologies, simple anti-foot drop devices lack design stability, especially when the bed is equipped with an anti-pressure sore air mattress. The device is prone to instability, shifting or tilting, which may affect the patient's exercise effectiveness. Simple devices may not be able to adjust the dorsiflexion and plantarflexion angles of the ankle joint, causing the patient's ankle to remain at a fixed angle, limiting the flexibility and effectiveness of exercise. For patients requiring exercises at different angles, such devices are clearly unsuitable. The devices may also be made of rigid materials or have an inhumane design, causing discomfort during use. For example, some devices may completely cover the sole, heel, and calf, which, while effectively preventing foot drop, may cause pressure sores on the heel in bed-bound patients due to the rigid material. Furthermore, simple anti-foot drop devices lack warmth retention, leaving the patient's limbs frequently exposed to cold. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a constant temperature rotating anti-foot sagging device, which solves the problems of low flexibility and poor heat retention in the existing technology.

A motor 5 is installed on the inner bottom wall of the rotating block 40, and a first gear 51 is installed at the output end of the motor 5. A chain 52 is mounted around the output end of motor 5. A shaft 53 is mounted on the inner bottom wall of the rotating block 40. The output end of motor 5 is connected to the shaft 53 via a sprocket and chain 52. A first half-tooth gear 54 is mounted on the outer wall of the shaft 53. A second shaft 55 is mounted on the inner bottom wall of the rotating block 40. A second gear 56 is mounted on the outer wall of the second shaft 55 and meshes with the first gear 51. A second half-tooth gear 57 is mounted on the outer wall of the second shaft 55. Both the first half-tooth gear 54 and the second half-tooth gear 57 mesh with the gear groove 42.

[0028] Specifically, after the patient puts on the device, the motor 5 is started. The motor 5 drives the chain 52 and the first shaft 53 to rotate. At this time, the first shaft 53 drives the first half gear 54 to rotate. The first half gear 54 drives the gear groove 42 and the rotating column 41 to rotate clockwise, thereby driving the patient's foot to rotate and exercising the patient's ankle joint. When the first half gear 54 is no longer meshed with the gear groove 42, the first gear 51 drives the second gear 56 and the second shaft 55 to rotate. The second shaft 55 drives the second half gear 57 to rotate. The second half gear 57 drives the gear groove 42 to rotate in the opposite direction, thereby enabling the patient's foot to rotate in two directions respectively, which facilitates the patient's rehabilitation.

[0029] It should be noted that when the patient wears this device, the anti-slip block 43 contacts the ground, which allows the patient's feet to rotate, and the rotation can effectively exercise the patient's ankle joints.
