[0023] Embodiment 1:

[0024] In this embodiment, an ankle pump exercise aid, such as Figure 1As shown, it includes an assistive device body. Specifically, the assistive device body includes a pad 1, a pedal 2 and a torsion spring. The pad 1 is used to support the patient's lower limbs. The lower limbs are pressed on the pad 1 to prevent the pad 1 from moving. The pedal 2 is used to cooperate with the sole of the foot to perform ankle pump exercises. The pedal 2 is rotatably connected to the front end of the pad 1 through a rotating shaft 3. The torsion spring is sleeved on the rotating shaft 3 and its two ends are respectively abutted against the pad 1 and the pedal 2. A counting device is also included. The counting device is installed on the pedal 2 to record the number of times the pedal 2 is pressed down by the sole of the foot.

[0025] With this structure, when in use, the patient lies flat with his legs on the pad 1, the soles of the feet press against the pedal 2 and overcome the resistance of the torsion spring to press the feet forward and then hook the feet backward, and the reciprocating motion achieves the exercise effect. The counting device records each time the soles of the feet are pressed forward to achieve the effect of accurate counting. The structure is simple and easy to operate, and the automatic counting saves manpower and improves the effect, making the utility model more practical.

[0026] In this embodiment, Figure 1 As shown, there are two auxiliary device bodies, corresponding to the left leg and the right leg respectively, and also include a telescopic rod, which is connected between the two pads 1. The distance between the two auxiliary device bodies is adjusted by the telescopic rod to meet the needs of patients with different body shapes.

[0027] Specifically, the telescopic rod includes a fixed rod 4 and a movable rod 5, one end of the movable rod 5 is movably connected in the fixed rod 4, the other end of the movable rod 5 is fixedly connected to the other of the pads 1, one end of the fixed rod 4 is fixedly connected to one of the pads 1, and the other end of the fixed rod 4 is provided with a locking bolt 6 for locking the movable rod 5. After adjusting the position of the movable rod 5, it is fixed by the locking bolt 6 so that the two pads 1 maintain a fixed distance. As an optimization, the number of the telescopic rods can be two, which are parallel and spaced apart and connected between the two pads 1.

[0028] As a specific implementation of this embodiment, Figure 1 As shown, the counting device includes a pressure sensor 7 and a counter 8. The pressure sensor 7 is arranged on one of the pedals 2. The pressure sensor 7 is electrically connected to the counter 8. When the ankle pump movement occurs, the force exerted by the sole of the foot pressing forward on the pedal 2 and the pressure sensor 7 and the backward hooking action reduces the pressure on the pressure sensor 7. The reciprocating motion causes the pressure received by the pressure sensor 7 to change periodically in the form of peaks and troughs. The counter 8 records the number of peaks each time, thereby obtaining the number of ankle pump movements.

[0029] In this embodiment, a groove is provided on the front side of one of the pedals 2, and the sensing element of the pressure sensor 7 is installed in the groove. The number of the grooves and sensing elements can be multiple. The pressure sensor 7 is fixed on the back side of the pedal 2. A wire hole is provided at the bottom of the groove. The wire of the pressure sensor 7 is electrically connected to the sensing element after passing through the wire hole. The sensing element is deformed by external force, and then converted into an electrical signal and transmitted to the counter 8.

[0030] In this embodiment, it also includes a first strap 9, and multiple first straps 9 are fixed on the above-mentioned pad 1 to fix the patient's legs. It also includes a second strap 10, and at least one second strap 10 is fixed on the above-mentioned pedal 2 to fix the patient's feet, so that the auxiliary device can be fixed on the patient's legs to prevent the legs and feet from detaching from the auxiliary device during ankle pump exercise.

[0031] As an optimization, a sponge pad 11 is further included. The sponge pad 11 is glued to the front side of the pedal 2 to improve the patient's comfort. The thickness of the sponge pad 11 should not be too thick to avoid affecting the pressure sensed by the pressure sensor 7.

[0032] In this embodiment, a protractor plate 12 is also included. The protractor plate 12 is fixed to one side of the front end of the pad 1, and the center of the protractor plate 12 is aligned with the rotating shaft 3. The protractor plate 12 can be used to visualize the amplitude of the patient's ankle pump movement so as to provide guidance.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
