Description

[0001] FOOT STRETCHING DEVICE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a foot stretching device, and more particularly, to a foot stretching device capable of preventing an ankle joint build-up due to a knee injury caused by nerve palsy such as stroke and cerebral palsy, ≪ / RTI >

With the development of medicine, the mortality rate due to the disease has been remarkably decreasing, especially the demand for rehabilitation is continuously increasing. However, contrary to the demand for rehabilitation, which is continuously increasing, the infrastructure for it is still in a harsh condition and urgent improvement is needed.

The domestic stroke population is 780,000 and the global stroke population is 35,000,000. The domestic stroke market is 836.8 billion won and the stroke overseas market is 40 trillion won. As of 2010, direct medical expenses for stroke totaled 1.666 trillion won, corresponding to 3.98% of total medical expenses of 41.85 trillion won in the National Health Insurance (2012, Kwon Young Dae, etc.) And about 18,000,000 patients are emerging each year.

The number of patients with cerebral palsy disease, which is a typical disease with difficulty in normal walking, is also increasing. The US Cerebral Palsy (UCP) Foundation has a population of 764,000, or 0.24% of the US population of 320 million, of which 17.3 million people suffer from cerebral palsy worldwide, accounting for 0.24% of the world's population (World Cerebral Palsy Day Association). The incidence of cerebral palsy in Korea is 0.15% ~ 0.2% of the total population, with 7 per 1,000 births or 7 per 100,000 people per year and 3.2 per 1000 children (2010, Health Insurance Review and Assessment Service). In addition to cerebral palsy, foot drop symptoms are increasing in various diseases such as Charcot marie tooth disease, spinal cord injury, peroneal nerve palsy, and multiple sclerosis.

In the existing method of rehabilitation of foot-and-mouth rehabilitation, when a person uses a towel or a towel instead of a specialist to directly push and pull, it is easy to give up rehabilitation. Granger, Shewood, and Greer (1977) reported that even if they receive rehabilitation after a disability, if they stop treatment before the function is completely restored, the daily activity score decreases, but if the rehabilitation is started again, And the need for a support system for

It is difficult for most modern people who are busy with work and school life to independently set up exercise time. According to the actual condition of participation in sports in 2013, 47.8% of men and 43.3% of women participated in sports activities more than once a week. Nevertheless, in the market, there is no stretching method that utilizes the sleeping time so that busy modern people can use the time efficiently.

Currently, there are no domestic or overseas devices that can stretch the calf muscles 'automatically' by stretching their toes.

There are many types of wearable bands. Typically, there is a footwear-wearing band "Plantar Fasciitis Foot Night Support" from Muller of Germany and a footdrop night splint from AliMed. In Korea, there is a foot support device from Aider. However, all of them are in a form to press their toes throughout their wear and are not stretching mechanisms, making them difficult to wear for a long time. The development of an automatic stretching mechanism that pulls a toe is not yet developed. Therefore, it is desirable to develop home self-treatment equipment equipped with physiotherapeutic programs.

In particular, resting splints, which have been introduced in the past, can not adjust the angle of the ankle joint, so that they can appeal to the patient's discomfort while wearing them, can facilitate the construction with a limited angle, The type can be limited.

Here, there is a need to develop a 'foot stretcher' having a dynamic motion function in which contraction and relaxation are repeated, and a resting splint capable of adjusting an angle of ankle joint.

Referring to FIG. 1, a foot stretching apparatus 10 according to an embodiment may include a support plate 100, a rotation plate 200, a plurality of air pads 300, and a controller 400.

The support plate 100 may support the calf region of the body.

At this time, the support plate 100 may be formed to extend along the longitudinal direction of the calf of the body, and the legs of the patient may be placed during the ankle exercise.

A calf support cushion 110 may be disposed on the upper surface of the support plate 100.

The calf rest cushion 110 is for reducing the friction between the calf region and the support plate 100, and can provide comfort to the user.

In addition, the calf strap 120 may be connected to one side of the upper surface of the support plate 100.

The calf strap 120 may be provided to be able to wind the upper surface of the calf portion and the calf strap 120 may be detachably attached to the other side of the upper surface of the support plate 100.

2, the calf air pad 130 may be disposed on the inner surface of the calf strap 120. As shown in FIG.

The calf air pad 130 may secure the calf region to the support plate 100 by further compressing the calf region secured by the calf strap 120.

For example, the calf air pad 130 may include three air pads having a length extending along the length of the calf region and a width extending along the length of the calf strap 120, and three The air pads may be provided so as to be connected to each other in parallel.

Further, although not specifically shown, the foot stretching apparatus 10 may further include an air injection unit (not shown) for injecting air into the calf air pad 130. For example, the air injection unit may include an air pump for discharging air, a driving motor for driving the air pump, and a solenoid valve connected to the air pump to adjust the flow path of the air.

At this time, the air infusion or air injection pattern for the calf air pad 130 can be variously implemented through the automatic control of the air injection unit, for example, the driving motor and the solenoid valve.

The rotation plate 200 may be coupled to one end of the support plate 100 described above.

The pivoting plate 200 may be supported on the sole portion of the body.

At this time, a heel may be disposed at a position where the support plate 100 and the rotation plate 200 are connected.

A foot support cushion 210 may be disposed on the upper surface of the rotation plate 200. The foot support cushion 210 is designed to reduce friction between the sole portion and the plurality of air pads 300 during an ankle exercise, thereby providing comfort to the user.

Further, a foot strap 220 may be connected to one side of the upper surface of the pivot plate 200.

The foot strap 220 may be provided to surround the foot portion so as to provide a sense of stability to the patient during an ankle exercise.

Although not shown, the foot stretching apparatus 10 according to one embodiment includes a support plate 100 and an actuator (not shown) provided on the rotation plate to rotate the rotation plate 200 with respect to the support plate 100. [ Time).

The actuator can implement an ankle lifting operation or an ankle lifting operation by adjusting the rotation angle of the rotation plate 200 with respect to the support plate 100, and can implement the up and down stretching of the ankle. This can help stretch the calf muscles.

Specifically, the actuator includes a first gear provided on the support plate 100, a second gear provided on the rotation plate 200 and rotated in engagement with the first gear, and a second gear disposed between the support plate 100 and the rotation plate 200 And may include a cushioning member connected thereto.

At this time, it is needless to say that the actuator may further include a drive motor (not shown) for transmitting the rotational force to the first gear and the second gear. The driving motor is provided, for example, with a worm gear encoder motor, so that the rotation angle of the ankle can be precisely controlled.

Further, the first gear and the second gear may be designed so as not to be pushed by the ankle force of the patient, for example, the gear ratio of the first gear and the second gear may be set to 1: 2.

The buffer member may be provided, for example, as a gas shock absorber, and a backlash may be generated in the first and second gears to prevent the swing plate 200 from being shaken.

The above-described actuator can adjust the ankle's foot and foot-lowering stretches.

For example, when the rotation angle of the rotation plate 200 is set to +12 degrees and -25 degrees by the actuator, the ankle lifting angle of the ankle may be +12 degrees and the ankle lowering angle may be -25 degrees.

Specifically, when the ankle lifting and lowering operation modes are implemented, the rotating plate 200 is rotated by + 12 degrees from the neutral position and rotated downward by -25 degrees from +12 degrees by the actuator, And can be repeatedly driven in accordance with the set repetition times.

When the ankle walking mode is implemented, the rotating plate 200 is rotated by +12 degrees from the neutral position and returned from the +12 degrees to the neutral position by the actuator, It can be driven repeatedly according to the number of repetitions.

Finally, when the ankle lowering operation mode is implemented, the rotating plate 200 is rotated by -25 degrees from the neutral position by the actuator and returns from the -25 degree to the neutral position as one set, And can be driven repeatedly according to the set repetition times.

Thus, the actuator can automatically adjust the rotation angle of the rotation plate 200 according to the stretching operation to be implemented or the operation mode set by the controller 400.

On the other hand, a plurality of air pads 300, which can be inflated by air injection, may be disposed on one surface of the rotation plate 200, for example, the upper surface.

3 and 4, the plurality of air pads 300 includes a first air pad 310, a second air pad 320, a third air pad 330, a fourth air pad 340, And a fifth air pad 350.

The first air pad 310 may be disposed in contact with the center of the sole region, and may perform the massage function of the sole region by the air injection pattern.

The second air pad 320 may be disposed on the left side of the foot so as to be spaced apart from the first air pad 310 to guide the inward movement of the ankle based on the right foot have.

The third air pad 330 may be disposed on the right side of the foot pad and the second air pad 320 in a direction away from the first air pad 310 toward the toe. At this time, the third air pad 330 can induce the external operation of the ankle based on the right foot by the air injection pattern.

For example, when the stepping up operation of the ankle by the actuator is implemented, air is injected into the second air pad 320 to implement the inner operation of the ankle, and when the stepping down operation of the ankle by the actuator is implemented Air can be injected into the third air pad 330 so that the external operation of the ankle can be realized.

The fourth air pad 340 may be disposed on one side of the first air pad 310 and the second air pad 320, for example, on the left side of the foot portion, away from the left side.

The fifth air pad 350 may be disposed on one side of the first air pad 310 and the third air pad 330, for example, on the right side of the foot portion, away from the right side.

At this time, the fourth air pad 340 and the fifth air pad 350 may be disposed symmetrically with respect to the first air pad 310. The fourth air pad 340 is connected to the first air pad 310 and the second air pad 320 so as to be bent upward from the left side of the sole portion and the fifth air pad 350 is connected to the first air pad 310, The first air pad 310 and the third air pad 330 so as to be bent upward from the right side of the sole portion.

Particularly, since the fourth air pad 340 and the fifth air pad 350 are disposed on the left and right sides of the instep portion, when the user wears the foot stretch apparatus 10, .

More specifically, when air is injected into the second air pad 320 or the third air pad 330, air may be injected into the fourth air pad 340 and the fifth air pad 350.

The fourth air pad 340 and the fifth air pad 350 are inflated by air injection so as to press both sides of the foot portion and the sole portion and fix the foot to the pivot plate 200 more stably . This may help to more accurately implement the inner and outer actions of the ankle by the second air pad 320 and the third air pad 330.

In addition, the pivotal movement of the ankle joint can be adjusted in the lateral direction by the air pattern injected into the fourth air pad 340 and the fifth air pad 350. Specifically, when air is injected into the fourth air pad 340, the ankle joint can be rotated in the right direction. When air is injected into the fifth air pad 350, the ankle joint is rotated in the leftward direction Can be exercised.

In this way, air is injected into the first air pad 310, the second air pad 320, the third air pad 330, the fourth air pad 340, and the fifth air pad 350, A massage function, an ankle inner and outer stretch, and an ankle pivot motion.

3, the first air pad 310, the second air pad 320, the third air pad 330, the fourth air pad 340, and the fifth air pad 340, The first air pad 310, the second air pad 320, the third air pad 330, the fourth air pad 340, and the fifth air passage 350 are connected to each other, It is a matter of course that the pads 350 can be individually mounted on the pivot plate 200.

Although not shown in detail, an air injection unit (not shown) for injecting air may be connected to the plurality of air pads 300.

The air injecting unit may include an air pump for discharging air, a driving motor for driving the air pump, and a solenoid (not shown) connected to the air pump to adjust a moving path of the air, It is of course possible to include a valve.

At this time, the air discharged from the air pump is discharged by the solenoid valve to the first air pad 310, the second air pad 320, the third air pad 330, the fourth air pad 340, 350 may be supplied by at least one of the first air pad 320 and the third air pad 330. For example, air may be supplied to only one of the second air pad 320 and the third air pad 330 through the operation control of the solenoid valve, An external operation can be implemented.

In addition, the air injection time for the plurality of air pads 300 can be controlled through the operation control of the driving motor. For example, if the air injection time is set to 15 seconds, the air injection may be continued for 15 seconds depending on each stretching operation or angle step, and may be repeated with a 15 second rest period. Through this, the muscles are repeatedly stretched and relaxed, so that the stretching operation can be performed for a long time.

Although the plurality of air pads 300 and the calf air pads 130 include different air injection units, it is needless to say that the same air injection unit may be shared by the support plate 100 or the rotation plate 200 and the air injection to the plurality of air pads 300 and the calf air pads 130 can be controlled through the operation control of one air injection unit.

For example, the aforementioned solenoid valve may be provided as a 3-way solenoid valve to regulate the air supplied to at least one of the plurality of air pads 300 or the calf air pad 130.

Thus, the foot stretching apparatus 10 according to the embodiment can be further miniaturized by being incorporated in the support plate 100 or the rotation plate 200, and can be easily handled by the user.

Referring again to FIG. 1, a controller 400 may be connected to the support plate 100.

The controller 400 may control the angle of rotation of the pivot plate 200 with respect to the support plate 100, the air injection to the plurality of air pads 300, or the stretching mode of the ankle.

In particular, referring to FIG. 5, an operation button, an operation display display, a status display display, and the like may be disposed on the upper surface of the controller 400.

The first button a is for turning on the power of the foot stretching apparatus 10 and the second button b is for actuating the driving motor and the air injection unit provided for the ankle And starts or stops driving by the provided driving motor.

The first display (c) guides the operating mode, the stretching operation, the air injection method, and the like.

The first light (d) indicates a part currently undergoing an ankle motion, the second light (e) indicates that an operation mode or a stretching operation is selected through the first display (c), and the third light f indicates that the pivot angle of the tilt plate 200 is selected through the first display c and the fourth light g indicates that the air injection site is selected through the first display c It is informing.

The third button h is a top / bottom selection button for selecting the cursor position from the first display c to the top / bottom, and the fourth button i is for selecting the menu from the first display c , And the fifth button (j) is for returning to the previous procedure guiding in the first display (c).

In particular, with reference to FIG. 6, the operation flowchart of the controller 400 is as follows.

The controller 400 may further include a control unit (MCU) and a communication unit as well as a plurality of operation buttons and operation display displays described above.

At this time, the items selected by the plurality of operation buttons can be collected in the control unit and transmitted through the communication unit.

In addition, the support plate 100 includes a power supply control unit connected to the adapter of the external power supply unit to control power supply, a communication unit for receiving signals transmitted from the communication unit included in the controller 400, A solenoid valve, an air pump, a status display, and a storage device (EEPROM), which are controlled by a control signal from a control unit, a control unit (MCU)

For example, the power supply control unit, the communication unit, the control unit, the drive motor, the solenoid valve, the air pump, the status display, and the storage device described above can be mounted in one board (main board).

Thus, the operation of the foot stretching apparatus 10 according to one embodiment can be controlled by the controller 400 as a whole.

In particular, the controller 400 may store at least one operating mode, and the pivot angle of the pivot plate 200 or the air injection to the plurality of air pads 300 may be adjusted according to the operating mode selected by the user .

The at least one operating mode may include an automatic mode, a user setting mode, and a manual mode.

In the automatic mode, the pivot angle of the pivot plate 200 or the air injection to the plurality of air pads 300 can be automatically adjusted according to the stretching operation selected by the user.

At this time, in the automatic mode, the function can be modularized based on the clinical research basis so that the user can use the effective stretching function in a simple manner.

For example, the controller 400 is equipped with an exercise protocol to select three main stretching movements and angles for each motion, and the selected mode can be automatically operated according to the stretching time developed by the clinician.

Specifically, the three main stretching movements are repeatedly operated by footsteps and externals, footsteps and inside movements repeatedly, footsteps and downstrokes composed of detailed functions according to the movement angle, footsteps and external motions repeatedly A step-down operation composed of a detailed function in accordance with a motion angle, and a step-down operation composed of a step-down operation in which only the step-down and step-in-motion repeatedly operate and the detailed function is configured in accordance with the motion angle.

At this time, the rotation angle of the rotation plate 200 or the air injection pattern for each stretching operation may be stored in the controller 400 in advance.

For example, in step 1, the pedaling angle may be +12 degrees and the pedaling angle may be -25 degrees. In the second step (step 2), the toe-up angle can be +19 degrees and the toe-down angle can be -35 degrees. In the third step (step 3), the foot lifting angle may be +25 degrees and the foot lowering angle may be -50 degrees. Thus, the user can adjust the stretching strength.

In the user setting mode, the foot up / down operation can be repeatedly operated only within an angle range set by the user.

Specifically, when the user setting mode is selected by the controller 400, the user can individually select an angle desired by the user of the foot-raising and lowering motions. For example, the foot-raising angle and the pedaling angle . Therefore, the user can first select the instep angle and select the instep descent angle in the controller 400.

In the manual mode, the pivot angle of the pivot plate 200 or air injection to the plurality of air pads 300 can be adjusted by a user.

In other words, the user can directly adjust the foot-raising angle and the foot-lowering angle from the controller 400 using the arrows.

The foot stretching apparatus according to an embodiment of the present invention allows the user to easily operate the foot stretching apparatus by selecting an operating mode after initial setting through a controller and sequentially selecting a footing angle and a footing angle for each stretching operation and operation.

On the other hand, although not specifically shown, a pressure sensor (not shown) may be disposed on the pivot plate 200 to sense a forearm or foot lowering force.

For example, the pressure sensor may be arranged so as to be in contact with the sole portion and the foot portion, and the pressure sensor for sensing the foot depression force may be disposed on the foot pad and the foot portion, 200, and a pressure sensor for sensing the foot-lifting force may be located inside the foot-strap 220.

The footstep or footstep force is detected by the pressure sensor, and the operation of the foot stretching apparatus 10 can be controlled by the force detected by the pressure sensor.

Specifically, the angle of rotation of the air injection or rotation plate 200 with respect to the air pad 300 can be actively controlled by a force sensed by the pressure sensor so that the patient can train his or her foot up or down movement. At this time, by adjusting the sensitivity of the pressure sensor, the angle of rotation of the air injection or rotation plate 200 with respect to the air pad 300 can be adjusted according to the performance of the patient.

It will be appreciated that when the operation of the foot stretching apparatus 10 is controlled by the above-described pressure sensor, the controller 400 may additionally be equipped with an assist active motion mode. When the user selects the assistant active motion mode in the controller 400, the air injection to the air pad 300 or the rotation angle of the rotation plate 200 can be adjusted from the value sensed by the pressure sensor.

Although not shown in detail, a limiter (not shown) may be connected between the support plate 100 and the rotation plate 200. When the value detected by the pressure sensor is greater than a preset value, the footrest stretching device 10 is operated to adjust the rotation angle of the rotation plate 200 or the air injection to the plurality of air pads 300 can do.
