[0002] In the field of foot support and related experimental testing equipment, existing support devices still have limitations. For example, Chinese patent CN102512197B discloses a bracket for assisting CT diagnosis of tarsometatarsal joint injuries. Its adjusting component is rotatably and slidably mounted on an inner tube, and the foot fixation component and foot pedal are fixedly connected to the adjusting component. The foot fixation component and foot pedal can help maintain the patient's foot at the angle and position required for CT diagnosis. However, the foot fixation component used in this bracket is semi-circular, only fixing the ankle. When applied to foot experimental testing, it suffers from insufficient stability and support. Furthermore, the bracket only provides foot support via the foot pedal, and the rotating and sliding structure of its adjusting component and inner tube cannot adapt to the different foot sizes and shapes of subjects, thus limiting its application range for foot experimental testing and failing to meet the needs of foot experimental testing.
[0003] Therefore, there is a need for a foot testing support device that can adapt to the foot size and shape of different subjects and provide stable support for the feet to ensure the accuracy of foot testing results, thereby providing more comfortable, accurate and flexible foot testing services for different subjects.

[0024] refer to Figures 1 to 5 This application provides a foot testing support device, including a mounting bracket 1, a foot instep support bracket 2, a foot sole support bracket 3, a mounting clamp 4, and a support pad 5. The foot instep support bracket 2 and the foot sole support bracket 3 are detachably mounted on the mounting bracket 1, facilitating the replacement of the foot instep support bracket 2 and the foot sole support bracket 3 for different foot testing experiments. The mounting clamp 4 is disposed on the mounting bracket 1 for mounting the mounting bracket 1 on a bed or experimental table. The support pad 5 is mounted on the foot instep support bracket 2 and the foot sole support bracket 3 for contact with the foot. The support pad 5 can prevent foot irritation and improve the comfort of the subject during foot testing experiments.
[0025] In a specific embodiment, refer to Figure 1 The mounting bracket 1 includes a transverse mounting bracket 11 and a longitudinal mounting bracket 12. The longitudinal mounting bracket 12 has several mounting holes 121 along its length. The transverse mounting bracket 11 is fixed to the mounting holes 121 of the longitudinal mounting bracket 12 by screws. The transverse mounting bracket 11 is used to mount the instep support bracket 2 or the plantar support bracket 3. Furthermore, two transverse mounting brackets 11 and two longitudinal mounting brackets 12 are provided to improve the stability of the mounting bracket 1, thereby enhancing the support of the foot experimental support device. By adjusting the mounting position of the transverse mounting bracket 11 on the longitudinal mounting bracket 12, the height of the instep support bracket 2 or the plantar support bracket 3 can be adjusted so that the instep support bracket 2 or the plantar support bracket 3 can adapt to different foot sizes of subjects, improving foot support and comfort during foot experimental testing. One end of the longitudinal mounting bracket 12 is provided with a mounting clamp 4. The mounting clamp 4 includes an upper clamping plate 41, a lower clamping plate 42, and a locking member 43 arranged along the length direction of the longitudinal mounting bracket 12. The locking member 43 is threadedly connected to the lower clamping plate 42. Specifically, the upper clamping plate 41 and the lower clamping plate 42 clamp the bed or experimental table. The locking member 43 is a screw. By rotating the screw, the distance between the end of the screw and the upper clamping plate 41 is adjusted, thereby fixing the mounting bracket 1 to the bed or experimental table to ensure stable installation. The foot experimental support device proposed in the embodiments of this application has a compact structure, is lightweight and portable, and is convenient for testers to install and use in different experimental locations.
[0026] In a specific embodiment, refer to Figure 1 and Figure 2The foot support bracket 2 includes a foot support plate 21, an upper support rod 22, and a lower support rod 23. The foot support plate 21 is saddle-shaped to better match the shape of the subject's foot. One end of the upper support rod 22 and the lower support rod 23 are connected to the foot support plate 21, and the other end is screwed onto the mounting bracket 1. Specifically, the upper support rod 22 is longer than the lower support rod 23. When the foot support bracket 2 is installed on the mounting bracket 1, the foot support plate 21 is inclined from top to bottom towards the mounting bracket 1, and both the upper and lower ends of the foot support plate 21 are bent towards the mounting bracket 1. The foot support bracket 2 is used to support the subject's foot to obtain the subject's plantar data. The instep of the human foot is curved. In the embodiments of this application, a curved saddle surface and an inclined foot support plate 21 are designed to conform to human foot ergonomics and adapt to the foot size and shape of different subjects. In addition, by adjusting the height of the foot support bracket 2 and the position of the subject, the instep of the subject can be fully fitted with the foot support plate 21, improving the support of the foot support bracket 2 for the subject's instep and enhancing the subject's comfort.
[0027] In a specific embodiment, refer to Figures 3 to 5 The foot support bracket 3 includes a foot support plate 31, a side support plate 32, and a foot mounting plate 34. The foot support plate 31 is mounted on the mounting bracket 1 and is arranged parallel to the mounting bracket 1. Specifically, when the foot support bracket 3 is installed on the transverse mounting bracket 11, the foot mounting plate 34, the foot support plate 31, and the transverse mounting bracket 11 are arranged parallel to each other. A recessed nut passes sequentially through the foot mounting plate 34, the foot support plate 31, and the transverse mounting bracket 11 to lock and fix the foot mounting plate 34 and the foot support plate 31 to the transverse mounting bracket 11. In the embodiments of this application, the thickness of the foot support bracket 3 is increased by the foot mounting plate 34 to facilitate the installation of the foot support plate 31 using a recessed nut. This avoids protruding nuts, screws, and other fasteners that could affect the support and comfort of the subject's foot, and also increases the strength of the foot support bracket 3, providing more stable support for the subject's foot. Furthermore, the foot support plate 31 has sliding grooves 33 on both sides, extending along its length. One end of each groove 33 is closed, and the side support plate 32 slides into and is installed within the groove 33 from the other end. The closed end of the groove 33 prevents the side support plate 32 from sliding off. Using the groove 33 to install the side support plate 32 facilitates its removal and installation according to foot testing requirements. This application not only supports foot testing of the sole and instep but also meets the needs of foot testing of the sides, providing support for the sides and facilitating testing, thereby enhancing the comprehensiveness of foot testing and meeting diverse needs in scientific research and clinical medical research.
[0028] The method of using the foot experimental support device proposed in this application is as follows:
[0029] During the foot plantar test, one side of the experimental table is placed between the upper clamp 41 and the lower clamp 42 of the mounting clamp 4, and the mounting clamp 4 is locked onto the experimental table using the locking member 43, thereby securely mounting the longitudinal mounting bracket 12 onto the experimental table. The upper support rod 22 and the lower support rod 23 are respectively mounted on the transverse mounting bracket 11 with screws. The position of the instep support bracket 2 is determined according to the size of the subject's foot, whether the subject's foot can fit the instep support bracket, or the needs of the foot experimental test. The transverse mounting bracket 11 is fixed to the mounting holes 121 of the longitudinal mounting bracket 12 with four screws. Then, the support pad 5 is fixedly installed on the instep support bracket 2. The subject is placed on the experimental table and adjusted to a comfortable position. Foot experimental tests such as pressure distribution measurement and pain sensitivity measurement are performed on the subject's foot, and the test data are recorded.
[0030] When conducting foot lateral tests, the side support plate 32 is installed in the groove 33 opposite to the side being tested. For example, when testing the left side of the foot, lateral support is provided for the right side of the foot, and vice versa. The support position is determined according to the size of the subject's foot or the needs of the foot experimental test. The subject is placed on the experimental table and adjusted to a comfortable position. Foot experimental tests such as pressure distribution measurement and pain sensitivity measurement are performed on the subject's foot lateral side, and the test data are recorded.
[0031] During the foot dorsum test, the foot dorsum support bracket 2 is removed from the horizontal mounting bracket 11 and replaced with the plantar support bracket 3, which is then installed on the horizontal mounting bracket 11 using a recessed nut. After fixing the plantar support bracket 3, its height is adjusted according to the subject's foot size or the needs of the foot experiment test. Before conducting the foot experiment test, the support pad 5 is fixedly installed on the plantar support bracket 3. The subject places their foot on the foot support bracket on the experimental table and adjusts it to a comfortable position. Foot experiment tests, such as pressure distribution measurement and pain sensitivity measurement, are performed on the subject's foot dorsum, and the test data are recorded.
[0032] During foot testing, the foot testing support device proposed in this application can provide stable support for the instep, sole, and sides of the foot to avoid inaccurate measurement data caused by foot movement due to external stimuli or other behaviors that affect the measurement data, thereby reducing errors and interference factors in the foot testing process and improving the accuracy of foot testing.
[0033] This application proposes a foot experimental support device with a foot instep support plate 21, a foot sole support plate 31, and a side support plate 32 that are easy to replace and disassemble, as well as an adjustable mounting bracket 1. It provides stable support for the instep, sole, and sides of the foot, and its flexible structure allows it to support various testing scenarios such as pressure distribution measurement and pain sensitivity measurement of the sole, instep, and sides of the foot. It is suitable for subjects of different ages and foot conditions, and can closely conform to the foot size and shape of different subjects. This solves the problems of existing support devices being unable to adapt to different foot sizes and shapes, having limited application range, and failing to meet the needs of foot experimental testing. It reduces testing errors caused by insufficient support or discomfort caused by the support device. It features high flexibility, strong scalability, and wide applicability, and has broad application prospects in scientific research and medical fields.
