Technical Field
[0001] The utility model relates to the technical field of foot care, and particularly relates to a device for preventing foot drop. Background Technique
[0002] Foot drop is a common sequela of neurological diseases, commonly seen in patients with stroke, incomplete spinal cord injury, cerebral palsy, multiple sclerosis, etc. The number of patients with these diseases is huge, and with the aggravation of the aging trend of the population, the number of related patients is expected to further increase, thus driving the market demand for devices for preventing foot drop. Foot drop is mainly manifested as the plantar flexion position of the ankle joint, and patients cannot actively dorsiflex, showing the phenomenon of toe touching the ground and heel hanging in the air. Foot drop will not only cause inconvenience to patients in walking, affect beauty and quality of life, but also may lead to ankle joint ankylosis and loss of corresponding functions in the long term;
[0003] During the use of the existing foot drop prevention devices, there are at least the following drawbacks: 1. The existing devices cannot flexibly adjust the angle and height according to the needs of patients, which brings a lot of inconvenience to patients during use, affects the patient experience, and slows down the recovery speed; 2. The existing devices have poor use effects. For example, the T-shaped shoes may cause redness on the dorsum of the foot and heel, and even cause pressure injuries, reducing the comfort of patients. Therefore, we have developed a device for preventing foot drop. Content of the Utility Model

[0032] Through the above solution: Since the height, body shape and condition of each patient are different, it can be adjusted according to the specific situation of different patients. When lying flat, lying on the side or sitting up, it can ensure that the device closely fits the patient's foot, providing personalized support. By adjusting the angle, it can ensure that the patient's foot and calf maintain an appropriate angle, preventing foot drop caused by long-term poor posture. At the same time, an appropriate support height also helps to maintain the functional position of the ankle joint, reducing the risk of foot drop. It can also help to adjust the position of the foot so that it is in a state conducive to blood circulation. This helps to reduce complications such as swelling and pain caused by poor blood circulation. Adjust according to the patient's feelings to avoid unnecessary pressure on the patient's foot caused by the device. This helps to improve the patient's comfort and reduce the discomfort caused by wearing the device for a long time. The operation is simple and the structure is clear, which helps to improve work efficiency and nursing quality.
[0033] In this embodiment, the leg pressing mechanism 4 includes a first motor 41. The output end of the first motor 41 is fixedly connected to a first rotating rod 42. A support base 43 is fixedly connected to the outer surface of the first rotating rod 42. An airbag 44 is fixedly connected to the front end of the support base 43. An elastic wrapping pad 45 is fixedly connected to the upper end of the airbag 44. An air pump connection port 46 is opened at the left end of the airbag 44.

The right end of the first motor 41 is movably connected to the vertical frame 1, and the outer surface of the first rotating rod 42 is slidably connected to the inner wall of the sliding groove 2.
[0034] Through the above solution: massaging the patient's legs can directly promote blood circulation in the legs. The acceleration of blood circulation helps to reduce blood stasis caused by long-term bed rest or fixed postures, and reduces the risk of deep vein thrombosis in the lower extremities. Good blood circulation can also provide more oxygen and nutrients to the feet, which helps to improve the nutritional status of foot tissues and promote the repair and regeneration of damaged tissues. Massaging the muscles and tendons of the feet helps to relieve muscle tension and stiffness caused by long-term inactivity or fixed postures. This is of great significance for preventing foot drop and improving the comfort of patients. By massaging, the long-term pressure on the legs can be reduced, and the risk of pressure ulcers (pressure injuries) can be lowered. This is particularly important for patients who need to stay in bed for a long time. At the same time, the provided massage effect can bring a comfortable experience to the patient, which helps to relieve the physical and mental stress caused by the disease and bed rest. This sense of comfort helps to improve the overall rehabilitation effect and quality of life of the patient. Enhancing the flexibility and range of motion of joints. For some patients with foot drop caused by neurological diseases, the massage mechanism can also stimulate nerve endings and promote the recovery and reconstruction of nerve function.
[0035] It should be noted that the present utility model is a device for preventing foot drop. During use, first, the leg pressing mechanism 4 is manually slid up or down to adjust according to the height of the chair or bed on which the patient is sitting. Then, an external air pump is connected to the air pump connection port 46, and the first motor 41 is started. The first motor 41 drives the first rotating rod 42 and the support base 43 to rotate. The external air pump is started, causing the airbag 44 to deform and wrap and massage the lower leg, massaging the patient's leg, which can directly promote blood circulation in the leg. The acceleration of blood circulation helps to reduce blood stasis caused by long-term bed rest or fixed postures and reduces the risk of deep vein thrombosis in the lower extremities. Secondly, the second motor 51 is started. The second motor 51 drives the second rotating rod 52 and the connecting frame 53 to rotate. After the foot pressing mechanism 5 is rotated to the required angle as a whole, the electric telescopic column 54 is started, causing the sliding rod 56 to slide in the fixed block 59, driving the foot placement plate 57 to adjust the distance. Finally, the micro motor 581 is started, driving the third rotating rod 582 and the main massage block 583 to rotate. The main massage block 583 drives the movable rod 584 to rotate, and the movable rod 584 drives the secondary massage block 585 to displace. At the same time, the strengthening rod 586 displaces and is adjusted to the required angle to ensure that the device can closely fit the patient's foot sole and provide personalized support. By adjusting the angle, it can be ensured that the patient's foot sole and lower leg maintain an appropriate angle, preventing foot drop caused by long-term poor postures. At the same time, massaging the foot helps to reduce complications such as swelling and pain caused by poor blood circulation.
