Abstract
Description
Technical Field
[0001] The present invention relates to the field of medical auxiliary devices, and particularly to a foot rehabilitation device based on liquid flexible contact. Background Art
[0002] Foot rehabilitation is an important part of the functional reconstruction for patients with lower limb dysfunction caused by diseases, surgeries, or traumas. The ankle pump exercise is a simple and effective lower limb rehabilitation method. By repeatedly flexing and extending the ankle joint, it simulates the natural blood pumping mechanism during walking, thereby promoting blood circulation in the lower limbs, reducing venous stasis, and preventing thrombus formation. This exercise has a significant effect on improving blood circulation in the feet and enhancing the strength and flexibility of the muscles around the ankle joint. The foot rehabilitation device is designed based on the principle of the ankle pump exercise. Traditional rehabilitation devices mostly adopt rigid support structures or fixed pressure distribution designs, having two major pain points: First, static support is difficult to adapt to the dynamic biomechanical changes of the foot, easily causing local pressure concentration and resulting in secondary soft tissue injuries; Second, there is a lack of precise control over temperature, motion patterns, and the foot microenvironment, affecting blood circulation and rehabilitation efficiency. In addition, existing devices generally cannot meet the dual requirements of rehabilitation training and in-bed rehabilitation. Patients need to change devices when switching body positions, which not only increases the operation complexity but also affects the continuity of rehabilitation.
[0003] To address the above problems, the present technology proposes a foot rehabilitation device based on liquid flexible contact. By constructing a partitioned liquid buffer system with a multi-chamber partition, combined with dynamic liquid vesicles, deployable extension plates, and an intelligent temperature control module, it realizes adaptive pressure distribution for the foot, multi-position adaptation, and optimization of the rehabilitation environment, breaking through the rigid limitations of traditional devices and providing a safer, more comfortable, and efficient solution for foot rehabilitation. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION
[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

A pulling rope 8 is connected through the middle of the shoe base 1, assistive balls are arranged at both the left and right ends of the pulling rope 8, the pulling rope 8 is slidably connected with the shoe base 1, twelve liquid vesicles 9 are arranged on the pulling rope 8, the liquid vesicles 9 can provide support and protection for the patient's sole after being filled with water, a water inlet pipe 10 is connected between the liquid vesicles 9, two symmetrically arranged connecting frames 11 are rotatably connected to the right part of the shoe base 1, an extension plate 12 is rotatably connected to each of the connecting frames 11, the extension plate 12 can be unfolded when the patient lies flat to provide stable support for the patient's foot and prevent the patient's foot from swinging. Two air bags 13 are arranged on the left part inside the shoe base 1, an air inlet pipe 14 is arranged on the air bags 13, the continuous expansion and contraction of the air bags 13 can assist the front end of the patient's foot to perform slight movements to assist in rehabilitation training. A temperature control component 15 is arranged inside the shoe base 1, the temperature control component 15 is used to control the temperature of the entire device and the liquid in the space to improve comfort.

[0027] It should be noted that when the patient wears the device, first, the split rehabilitation shoe side cover 3 is adapted to the rehabilitation shoe body 2, and the wrapping range of the side cover is adjusted by the adhesion of the first magic tape 4 on the left side and the second magic tape 5 on the right side.
