[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1-4 The utility model discloses a functional regulator for preventing foot drop, comprising a base plate 1 and a fixing seat 2. The fixing seats 2 are symmetrically arranged on the upper surface of the base plate 1, and the two fixing seats 2 are slidably connected to the base plate 1. The sliding connection between the fixing seats 2 and the base plate 1 can be used to adjust the distance between the two fixing seats 2, thereby facilitating the adjustment of the distance between the patient's feet and improving the practicality of the device.

[0025] The functional regulator for preventing foot drop provided in this embodiment also includes a placement groove 3, which is opened in the fixing seat 2, and the two side walls of the placement groove 3 are symmetrically installed with limiting capsules 6, and the outer side of the limiting capsules 6 is evenly provided with limiting protrusions 7. The other inner wall of the placement groove 3 is provided with a supporting capsule 5, which is used to support the patient's foot arch.

[0026] In this embodiment, the foot is fixed in an enclosed manner by setting the placement groove 3, thereby improving the foot support effect. By controlling the internal inflation of the support bag 5, the arch of the foot is supported and the foot is allowed to move around the contact position between the sole of the foot and the placement groove 3, thereby realizing the adjustment of the foot support angle. By setting the limiting bag 6 and the limiting protrusion 7, the instep is limited, thereby preventing the foot from leaving the placement groove 3, thereby improving the practicality of the equipment.

[0027] like Figure 1 and Figure 2As shown, in order to achieve internal inflation of the support bag 5 and the limiting bag 6, an air pump 8 is fixed at one end on the upper surface of the base plate 1, and a bellows 9 is installed at the output end of the air pump 8. The setting of the bellows 9 is conducive to inflating the support bag 5 and the limiting bag 6 when the distance between the fixing seat 2 changes. The bellows 9 is connected to the support bag 5 and the limiting bag 6 pipelines in the two fixing seats 2. By controlling the internal inflation of the support bag 5, the arch of the sole of the foot is supported and the foot is moved around the contact position between the sole of the foot and the placement groove 3, thereby realizing the adjustment of the foot support angle. By inflating the limiting bag 6, the instep is limited, thereby preventing the foot from leaving the placement groove 3, thereby improving the practicality of the equipment.

[0028] like Figure 1-Figure 3 As shown, in order to adjust the distance between the two fixed seats 2, bearing seats are provided on the upper surface of the base plate 1 near both ends, and a bidirectional screw rod 4 is rotatably installed between the two bearing seats. The bidirectional screw rod 4 is threadedly connected to the fixed seat 2, and one end of the bidirectional screw rod 4 passes through one of the bearing seats and is installed with a knob. The bidirectional screw rod 4 is driven by the knob, and the thread force generated by the threaded connection between the bidirectional screw rod 4 and the fixed seat 2 causes the two fixed seats 2 to move toward each other.

[0029] like Figure 1-Figure 3 As shown, in order to improve the stability of the fixed seat 2 during movement, a slide groove 10 is provided on the lower surface of the fixed seat 2, and a slide rail 11 is provided on the upper surface of the base plate 1 for sliding connection with the slide groove 10. The sliding connection between the slide groove 10 and the slide rail 11 improves the stability of the fixed seat 2 during movement.

[0030] like Figure 1 and Figure 4 As shown, in order to improve the comfort during foot treatment, sponge pads are placed in the corners and bottom of the placement groove 3. The sponge pad is an integrated structure, and a rubber pad is provided at the bottom of the sponge pad. Through the setting of the rubber pad, the friction between the sponge pad and the placement groove 3 is improved, thereby improving the stability of the sponge pad during use. In addition, after the foot is placed on the sponge pad, the sponge pad is concave, further wrapping the foot and improving the stability of the foot during support.

[0031] like Figure 1 and Figure 3 As shown, in order to improve the stability of the base plate 1 when it is placed, an anti-slip pad is installed on the lower surface of the base plate 1, and the anti-slip pad is glued to the base plate 1, thereby improving the contact stability between the base plate 1 and the bed.

[0032] like Figure 1 As shown, in order to improve the stability of the base plate 1 after installation, fixing rings 17 are fixed on the lower surface of the base plate 1 near both ends, and a binding rope 16 is installed on one side of the fixing ring 17. Preferably, there are two fixing rings 17 on the same side. Through the cooperation between the fixing ring 17 and the binding rope 16, the four corners of the base plate 1 can be fixed, thereby improving the stability of the base plate 1 after installation.

[0033] like Figure 2 and Figure 5 As shown, in order to improve the air flow inside the placement slot 3, an air cavity 15 is opened inside the fixing seat 2, a ventilation window 13 is opened on one side of the air cavity 15, and exhaust holes 12 are evenly opened on the side of the air cavity 15 close to the placement slot 3. A circulating fan 14 is fixed inside the air cavity 15. Under the setting of the air cavity 15, the circulation fan 14, the ventilation window 13 and the exhaust hole 12, the air flow inside the placement slot 3 is accelerated, thereby avoiding sweating of the feet during foot treatment and affecting the patient's comfort. In addition, an electric heating tube can be optionally installed at the position of the exhaust hole 12 inside the air cavity 15 to heat the exhaust air to avoid cold feet in cold seasons and affecting the patient's health.

[0034] The working principle and use process of the present invention are as follows: when in use, the base plate 1 is placed at one end of the bed, and the four corners of the base plate 1 can be fixed by the cooperation between the fixing ring 17 and the binding rope 16, thereby improving the stability of the base plate 1 after installation, and the knob is turned to drive the bidirectional screw rod 4. The thread force generated by the threaded connection between the bidirectional screw rod 4 and the fixing seat 2 is used to improve the stability of the fixing seat 2 when moving through the sliding connection between the slide groove 10 and the slide rail 11, so that the two fixing seats 2 move toward each other, thereby adjusting the distance between the two fixing seats 2, and placing the foot inside the placement groove 3. Through the setting of the placement groove 3, the foot is surrounded and fixed, which improves the stability of the fixing seat 2 when moving. To achieve high foot support effect, start the air pump 8 and inflate the support bag 5 and the limiting bag 6 through the bellows 9. By controlling the inflation inside the support bag 5, the arch of the sole of the foot is supported and the foot is allowed to move around the contact position between the sole of the foot and the placement slot 3, thereby realizing the adjustment of the foot support angle. Through the setting of the limiting bag 6 and the limiting protrusion 7, the instep is limited to prevent the foot from leaving the placement slot 3, thereby improving the practicality of the equipment. In addition, with the setting of the wind cavity 15, the circulating fan 14, the ventilation window 13, and the exhaust hole 12, the air flow inside the placement slot 3 is accelerated, thereby avoiding sweating of the foot during foot treatment and affecting the patient's comfort.
