Technical Field

[0001] The utility model relates to the technical field of clinical nursing auxiliary appliances, in particular to a foot supporter for preventing foot drop in paraplegic patients. Background Art

[0002] Foot drop is one of the signs of orthopedics. When the patient sits, the two lower limbs hang naturally. If the foot is in plantar flexion and cannot actively dorsiflex or evert or turn inward or outward, it is foot drop. This sign can be seen in sciatic nerve paralysis and common peroneal nerve paralysis. In the former, the toes can neither dorsiflex nor plantar flex, while in the latter, the toes can plantar flex. In addition, this sign can also be seen in poliomyelitis, progressive muscular dystrophy, hypokalemic periodic paralysis and lower limb paralysis. Patients with lower limb fractures and paraplegia are at high risk of foot drop. Therefore, there is an urgent need for a plantar support device to prevent foot drop.

[0003] To solve the above problems, the prior art patent (CN208926741U) discloses a foot support for preventing foot drop in patients with lower limb fractures and paraplegia, specifically a foot support for preventing foot drop in patients with lower limb fractures and paraplegia, comprising a foot support plate, one side of the foot support plate is fixedly connected to a lifting column, and the outer surface of the lifting column is fixedly connected to a lifting controller. The foot support for preventing foot drop in patients with lower limb fractures and paraplegia, through the design of the lifting column and the lifting controller, realizes the function of adjusting the height of the foot support plate, thereby achieving the purpose of supporting the soles of bedridden patients of different heights, making the device more practical and easy to operate. In addition, by opening a fixing hole on one side of the bottom plate, the function of fixing the device is realized, preventing the foot support plate from moving due to external factors when the patient uses it, thereby reducing the pain to the patient.

[0004] However, in the above-mentioned prior art, the distance between the two feet cannot be adjusted according to the needs of the patient. Wearing the device for a long time will cause discomfort to the patient's feet and reduce the patient's recovery progress. Utility Model Content
