Description

Technical Field

[0001] This utility model relates to the field of rehabilitation assistive device technology, and in particular to a foot exercise rehabilitation training device. Background Technology

[0002] Prolonged standing, walking, or running puts excessive pressure and strain on the plantar fascia, easily leading to injury and inflammation. For example, long-distance runners and people who need to stand for long periods at work, such as teachers and salespeople, have a higher risk of plantar fasciitis. Sitting at a desk for long periods increases the burden on the plantar fascia due to body weight, putting greater pressure on the sole of the foot and increasing the risk of disease. Flat feet or high arches: Abnormal foot structure alters the way the plantar fascia bears weight, making it more susceptible to injury. People with flat feet have low arches, causing the plantar fascia to be under constant tension; people with high arches experience greater strain on the plantar fascia during walking due to the high arch.

[0003] While existing training devices can reciprocate the foot fixation device through their telescopic drive mechanism to train the dorsiflexion movement of the patient's foot, they cannot adjust the range of motion according to different stages of the patient's rehabilitation, making them inconvenient for different groups of people.

[0031] like Figure 1 and Figure 2 As shown, a foot exercise rehabilitation training device includes a support base, a footrest, a calf support, and a drive bracket. The footrest, calf support, and drive bracket are all hinged to the support base. The angle between the support base and the drive bracket is adjustable, and the angle between the calf support and the drive bracket is also adjustable. The footrest includes:

[0032] The arch plate 1 has a first side plate 2 that extends vertically upward on each side. The top of each first side plate 2 is hinged to the support base, and the arch plate 1 is connected to the drive bracket in a transmission manner.

[0033] The foot plate 3 has a second side plate 4 that extends vertically upward on each side. Each second side plate 4 has a first connecting plate 5 fixed at one end near the arch plate 1. One end of each first connecting plate 5 is hinged to the end of the first side plate 2 away from the drive bracket.

[0034] A drive assembly is fixedly mounted at the bottom of the arch plate 1. The working end of the drive assembly is connected to the bottom of the foot plate 3 for transmission, so that the foot plate 3 can adjust the angle between itself and the arch plate 1 according to the patient's needs.

[0035] For example, by setting up a support base and a drive bracket, the drive part and the motion part can be separated to avoid mutual interference and improve the stability of the trainer structure. By adjusting the angle of the drive bracket and the lower leg bracket, the trainer can adjust the range of motion according to the different stages of the patient's rehabilitation and their own condition, and can adapt to training in lying and sitting positions. The drive component drives the foot plate 3 to move, so that the foot plate 3 rotates under the influence of the first connecting plate 5 and forms an angle with the arch plate 1 to stretch the patient's toes. Through the two-stage upward folding method, not only can the ankle be stretched towards the body, but the fascia can also be stretched to the maximum extent by stretching the toes.

[0036] As an optional embodiment, the support base includes a base plate 6, and a third side plate 7 is fixed vertically upward on each side of the base plate 6. The top of each third side plate 7 is hinged to the top of the first side plate 2, the lower leg bracket, and the drive bracket, respectively.

[0040] At least two adjustment holes 12 are provided on the second connecting plate 9, and the third side plate 7 is detachably connected with an adjustment pin 13 adapted to the adjustment holes 12.

[0041] As an optional embodiment, the calf support includes a back plate 14 and two adjusting plates 15. One end of each adjusting plate 15 extends downward and is fixedly connected to the side of the back plate 14 in a perpendicular state. The other end is hinged to the top of the third side plate 7. Each adjusting plate 15 is provided with an arc-shaped through hole 16. Each arc-shaped through hole 16 is provided with a limiting slide rod 17 inside. One end of each limiting slide rod 17 is fixed on the side of the mounting frame 8. Each arc-shaped through hole 16 is provided with multiple locking holes 18 arranged along an arc-shaped trajectory near the hinge of the third side plate 7. A positioning pin 19 adapted to the locking hole 18 is detachably connected to the side of the mounting frame 8.

[0042] For example, by adjusting the pin 13 and the adjusting hole 12, the angle between the mounting frame 8 and the base plate 6 is controlled to adjust the initial use state between the mounting frame 8 and the arch plate 1, so as to adapt to training in lying and sitting positions. The first electric push rod 10 drives the third connecting plate 11 to move, the third connecting plate 11 drives the first side plate 2 to move, and the first side plate 2 drives the arch plate 1 to rotate around the third side plate 7, so as to adjust the angle between the mounting frame 8 and the arch plate 1. Through the cooperation between the positioning pin 19 and the locking hole 18, the adjusting plate 15 drives the back plate 14 to rotate around the third side plate 7, so as to adjust the angle of the patient's lower leg, thereby achieving the function of adjusting the range of motion according to the different stages of the patient's rehabilitation and their own condition.

[0043] As an optional embodiment, the first side plate 2 is provided with a flexible foot strap 20, and the adjustment plate 15 is provided with at least two flexible calf straps 21.

[0044] As an optional embodiment, the driving component includes:

[0045] The second electric push rod 22 is fixed to the bottom of the foot arch plate 1 by a bracket;

[0047] The connecting arm 24 has one end hinged to the bottom of the foot plate 3 and the other end hinged to the end of the connecting block 23 away from the second electric push rod 22.

[0048] For example, the second electric push rod 22 drives the connecting block 23 to move, the connecting block 23 drives the connecting arm 24 to move, the connecting arm 24 drives the foot plate 3 to move, and the foot plate 3 rotates due to the hinge effect of the first connecting plate 5 and the first side plate 2, so as to stretch the toes.

[0049] As an optional embodiment, both the arch plate 1 and the foot plate 3 are equipped with ceramic heating elements and temperature sensors. The temperature of the ceramic heating elements is adjustable from 25 to 40 degrees Celsius, and the temperature sensors are used for temperature monitoring.

[0050] As an optional embodiment, a thin-film pressure sensor is provided on the top surface of both the arch plate 1 and the foot plate 3, and the thin-film pressure sensor is used to evaluate the arch type and provide feedback, and to monitor the pressure distribution of the sole of the foot in real time.

[0051] As an optional embodiment, multiple electromyography (EMG) monitoring and stimulation electrodes are provided on the top surfaces of the arch plate 1 and the foot plate 3 for assessing calf muscle strength and stimulating deep muscles.

[0052] For example, this device can be used to add other wedges to the side of the foot to adjust the lower limb alignment and help restore normal alignment, making rehabilitation exercises more effective in this case.
