Description

Foot and drainage support

The present invention relates to a foot and lower limb support, and more specifically, a foot sagging symptom that occurs when nerve damage, muscle abnormality, muscle weakness, and non-nasal nerve paralysis occur due to stroke, hemiplegia, cerebral palsy, fracture, accident, etc. Wearing on the foot of a foot and foot patient who shows a foot, the foot is supported to lift and maintain the sag while walking, while improving the structure without the need for complicated mechanical or electrical configuration or structure It is about old foot drainage support.

Generally, foot drop (Foot drop;足下垂(foot prosthesis, can knock stretched down to, cast)) is a stroke, hemiplegia, cerebral palsy, fractures, nerve damage due to accidents, such as muscle or later, hypotonia, peroneal nerve palsy This is a symptom of various causes.

In the case of the nerve damage, for example, when the peroneal nerve (Peroneal Nerve) is damaged, the reason is that often occurs when the upper nerve of the nasal nerves during surgery, in addition to sports damage or diabetes Occasionally, a long-legged posture may occur.

In addition, muscle and nerve disorders are caused by genetic muscle disorders, polio, Sharco-Marie-Tooth disease, muscular dystrophy, Lou Gehrig's disease, and incomplete spinal cord injury.

In addition, in the case of brain or spinal cord disorder, the central nervous system damage is caused by stroke (cerebral infarction, cerebral hemorrhage), multiple sclerosis, cerebral palsy, incomplete spinal cord injury, Charco-Marie-Tooth disease and the like.

When the foot and foot symptoms appear, the front part of the foot cannot be lifted by themselves. These foot sagging patients feel inconvenient in their daily walking, such as a lack of power to lift the foot, causing them to stumble when walking.

In normal walking, the foot instep angle is about 10 degrees, and foot and foot patients have foot inversion angles of about -10 to -20 degrees, which is why they often walk while dragging their feet. There are many cases.

In order to compensate for this phenomenon, the knees are excessively raised and the walking pattern (steppage gait) is shown or the walking leg (circumduction gait) is displayed.

The gait walk is a pattern frequently occurring in patients with peripheral nerve (non-bone nerve) injuries, and the gait of luminance is frequently generated in diseases such as stroke (infarction, cerebral hemorrhage).

As an example, a conventional apparatus or apparatus for supporting the foot and leg water as described above, the Republic of Korea Patent Publication No. 10-1641344 (walking aid device for ankle; Document 1) and the Republic of Korea Patent Publication No. 10-0924842 (foot of paralyzed patients There is a control method of an active foot restraint device for preventing water and slipping;

Is provided, the footrest angle adjuster, the cylinder member penetrated up and down; A length adjusting body member coupled to any one of upper and lower sides of the cylinder member so as to be movable upward and downward to adjust the overall length; A rotation restoration body member coupled to the other side of the upper and lower portions of the cylinder member so as to be movable up and down; And a restoring spring member disposed in the cylinder member to elastically support the rotation restoring body member, wherein the length adjusting body member comprises: a moving body portion connected to the angle adjuster connection portion or the scaffolding body; And a moving screw ring body portion rotatably coupled to any one of an outer circumferential surface of the movable body portion and an inner circumferential surface of the cylinder member and screwed to the other side thereof.

On the other hand, Document 2 is a calf support that is supported between the knee and ankle joint support; Ankle joint control unit having a metal hinge joint, the rotatable potentiometer is connected to the rotating shaft of the metal hinge joint; In the method of controlling the driving unit by determining the walking period in the active short leg brace consisting of a foot support unit equipped with a big toe sensor, a first metatarsal head sensor, a fifth metatarsal head sensor, and a heel sensor as resistance sensors on the outer bottom thereof. When the heel sensor is in contact and other sensors are not in contact, and the potentiometer is "sheep", the gait period is determined as a step of converting the foot to a hind ground folding at the stator, and the foot ground (HS) at the hind ground ground (HS) FF), when the heel sensor, the fifth metatarsal base sensor, the first metatarsal head sensor, and the big toe sensor are in contact, it is determined as a conversion step (T2 step) from the heel folding to the foot folding. Is non-contact, other sensors are in contact, and when the potentiometer is "negative" Determination of the conversion to the lifter step (T3 step), when the heel sensor, the first metatarsal head sensor, the fifth metatarsal bone sensor is in a non-contact state, only the toe sensor is in contact with the toe lifter conversion step (T4) Step), and when all the sensors including the big toe sensor are in a non-contact state, the toe lifter is converted to the incline step (T5 step), and after the heel of the foot is lifted, the switch does not switch to the inclinator (SW) again. When all of the

sensors

120, 130, 140, and 150 are in contact with each other, when the sensor is switched to the sole folding machine FF, it is determined as a step (T6 step) from the lift of the rear axle to the foot folding machine. In the receiver D1, the motor control signal is generated to reduce the length of the driving unit 300 so that low buckling occurs. In the middle standing stage and the last standing angle D2, the length of the driving unit 300 is increased to increase the length of the driving unit 300. Generates a motor control signal, and because a large and fast bottom flexion is required in the all-inverter D3 section, generates a motor control signal that reduces the length of the drive unit 300 at the maximum speed. It is a method of controlling the driving unit by determining a walking cycle in an active short leg brace, characterized in that the motor control signal is generated so as to be sufficiently dragged so as not to be attracted to the ground, thereby controlling the driving unit.

However, the conventional foot and drainage support devices or supports as described above are very complicated in structure and structure, and have low manufacturing competitiveness, high manufacturing cost and high selling price, and low price competitiveness, and they are also troublesome to wear to the general public. .

In addition, when the total weight is heavy, the wearer easily feels fatigue by the weight when worn on the foot, and the foot is heavy, so there is a problem in that walking becomes difficult.
