[0023] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0024] Reference Figure 1 , Figure 2 , this embodiment discloses a foot function auxiliary pad, which can solve the problem of foot drop that patients with paraplegia, lower limb traction, lower limb plaster fixation, Achilles tendon contracture, coma and long-term bed rest are prone to. This foot function auxiliary pad includes a base pad 1 and a foot pad 2 arranged on the base pad 1. The base pad 1 is made of a flexible material, specifically made of rubber and other materials to improve its softness and comfort. The foot pad 2 is slidably connected to the base pad 1, and the foot pad 2 is provided with a foot groove 3 that matches the shape and size of the foot. When in use, the patient's foot is placed in the foot groove 3, so that the foot and toes are kept in the dorsiflexion position, and the ankle joint is kept in the functional position (flexed 90° neutral position), which can effectively reduce the risk of foot drop in the patient. In this embodiment, the foot pad 2 is provided with two, and both can slide on the base pad 1, and then the distance between the two foot pads 2 can be adjusted to meet the needs of different people for different foot opening distances. The foot pad 2 is provided with a restraint belt 10 connected to both sides of the foot groove 3. The patient's foot is better fixed and not easy to slip. The bottom pad 1 is provided with a mounting groove 4, in which a sliding device for slidingly connecting the foot pad 2 and the bottom pad 1 is installed. The mounting groove 4 is horizontal and rectangular, and the mounting groove 4 is detachably provided with a movable guide plate 5 with an opening in the middle. The movable guide plate 5 is made of a hard material, so that the movable guide plate 5 has a certain supporting force. Since the bottom pad 1 is made of a flexible material, the foot pad 2 has a large resistance during the sliding process, so the upper plate surface of the movable guide plate 5 is higher than the surface of the bottom pad 1. Under the support of the movable guide plate 5, the bottom surface of the foot pad 2 and the bottom pad 1 do not contact each other, and the foot pad 2 is equivalent to sliding on the movable guide plate 5, so that the foot pad 2 slides more smoothly.

[0025] When the patient's foot needs to be supported in a functional position, the movable guide plate 5 is inserted into the base pad 1, and the movable guide plate 5 can be removed when it is not needed. The sliding device can be configured to include a rack-shaped linear guide 6 arranged in the installation groove 4, and a caster 7 arranged under the foot pad 2, and the caster 7 is provided with teeth 8 meshing with the linear guide 6. After the patient's foot is placed in the foot groove 3, when the foot pad 2 needs to be moved, the foot pad 2 can be directly acted on. Since the teeth 8 mesh with the rack-shaped linear guide 6, the caster 7 is driven to roll along the linear guide 6, and the rolling of the caster 7 on the linear guide 6 realizes the sliding of the foot pad 2 on the base pad 1.

[0026] It should be noted that: in this embodiment, the caster 7 has a certain damping during the rotation process, and a certain external force is required to drive the caster 7 to roll on the movable guide plate 5. Therefore, after the rolling adjustment of the caster 7, its position can be automatically fixed without the help of additional external force. When it needs to be adjusted again, a certain additional force needs to be applied.

[0027] The bottom of the foot pad 2 is provided with a fixing plate 9 for mounting the caster 7, and the fixing plate 9 is slidably connected to the upper end of the movable guide plate 5. The fixing plate 9 directly slides in contact with the movable guide plate 5, further improving the smoothness of sliding. Figure 2 , the fixing plate 9 is rotatably connected to the caster 7. The angle of the foot pad 2 can be adjusted, for example, by adjusting the angles of the two foot pads 2, the patient's foot can maintain a slight angle of eight in a natural state, thereby improving the patient's comfort.

[0028] Similarly, the rotation between the bottom of the fixed plate 9 and the caster 7 has a certain damping, and a certain external force is needed to drive the fixed plate 9 to rotate. Therefore, after the rolling adjustment, the fixed plate 9 can automatically fix its position without the help of additional external force.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
