Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a human body supporting device for a walking training machine, and more particularly to a human body supporting device for a walking training machine that shares the weight of a pedestrian to assist walking training.

[Background technology]

Conventionally, for pedestrians such as patients who need walking training, with the help of a PT (occupational therapist) or a nurse, start training on a tilting platform, then use parallel bars, a walker, and a crutch. Phased training was common. In addition, training has been carried out by reducing the weight load by using the buoyancy of Hubbard tanks and pools for walking training. However, each of the methods has a disadvantage in that a pedestrian who cannot walk or is close to walking requires a lot of manpower and time including PT. In addition, the number of medical staff is limited, so there were problems such as insufficient training.

Therefore, a walking training machine has been developed that enables walking training with a small amount of muscle force and does not require a lot of human hands. This walking training machine has a main body that is the basic axis of this training machine and a lifting arm that is horizontally attached to the main body so that it can rotate horizontally by 360 ° and can move vertically by 30 °. A suspension unit attached to the end of the suspension arm unit to maintain the pedestrian's standing position, a load sensor such as a load cell to detect the load weight applied to the suspension unit, and the suspension force of the suspension arm unit The control unit controls the air cylinder so that the value is in accordance with the load, and adjusts the lifting force when a change in the load of the pedestrian is detected by the weight sensor.

The suspension portion is composed of, for example, a pair of frame members that intersect with each other via a connecting point, and has a cushion side arm support member that is applied to the side of a pedestrian at the lower end thereof.

In the above configuration, when the side support member of the suspension part is attached to the side of the pedestrian and the weight value of the pedestrian is input as the lifting command value, the control unit controls the air cylinder based on the input lifting command value. Then, the pressure in the air cylinder is adjusted so that the lifting force reaches the weight value when the pedestrian applies the entire weight. At this time, for example, weight 50kg
When a pedestrian of the whole is put on the entire weight, it will be suspended at 50 kg through the suspension part and the lifting arm part.
When a load of 40 kg is applied, 40 kg will be controlled by the control unit.
Will be suspended in. After confirming that the pedestrian's standing position is completely maintained by the lifting arm and the suspension, the walking training is started. The lifting arm unit rotates following the walk of a pedestrian. On the other hand, the weight load applied to the lifting arm during walking training is detected by the weight sensor, and the lifting force is controlled according to the weight load as described above. In this way, the device can perform gait training while reducing the weight load on the ground contact surface even when it is impossible to maintain the standing position at all. The weight load on the ground contact surface can be freely set to 1/2, 1/3 or 1/10 of the weight. As described above, by maintaining the standing position of the pedestrian during walking training and controlling the weight load with the device, it is possible to perform walking training with a small muscle force, and a walking training machine that does not require a large number of human hands. Could be realized.
During walking training, even if a pedestrian falls down and the weight sensor detects a load more than the weight, it is controlled so as not to exceed the lifting command value. Therefore, the risk of falling is prevented.

[Problems to be solved by the device]

However, according to the conventional walking training machine, since the armpit support member is applied to the side of the pedestrian, it is inconvenient for long-term use. That is, if the cushion is increased to improve the feeling, the armpits are too wide to apply the force, and it becomes difficult to support the weight. If the cushion is weak, the armpits become painful and it becomes difficult to use. Further, even if the armpit is shaped to fit the shape of the armpit and the weight is supported by the entire armpit, the blood vessels under the armpit are pressed, so that numbness or the like occurs in the arm.

[Means for Solving the Problems]

The present invention has been made in view of the above, and allows the walker to be used for a long time, so that the support portion of the pedestrian can be arbitrarily changed, and the pedestrian can grasp a plurality of points. (EN) Provided is a human body supporting device for a walking training machine.

That is, the human body supporting apparatus of the walking training machine of the present invention comprises the following means.

(1) A pair of rod-shaped members, with one side of the ring, square, or square removed It is composed of a pipe and is placed on both sides of a pedestrian. For this reason, pedestrians with their hands out forward,
The rod-shaped member can be gripped in the state of being lowered downward, or in the state of being raised and hung up, and also at other positions.

(2) Lifting Means The pair of rod-shaped members are lifted by the force of an air cylinder, a motor or the like. It is preferable that the hoisting point is moved up and down by being supported by an arm or the like that transmits hoisting force.

(3) Supporting means The lifting force received by the pair of rod-shaped members is applied to a pedestrian, and is configured by, for example, suspending a floating air bag on the pair of rod-shaped members with a string, a wire, or the like. It The air bag is applied to the underarm of the pedestrian and around the torso, thereby giving the pedestrian the lifting force received by the pair of rod-shaped members to support the pedestrian. The air bag may be replaced with a donut-shaped sponge or the like, but the air bag is preferable because the tightening force can be adjusted by the internal pressure.

[Action]

A pedestrian attaches a floating bladder to the armpit, around the torso, and holds an arbitrary point of the ring-shaped pipe with both hands. When the start switch of the pedestrian training machine is turned on,
The pedestrian is supported via a ring-shaped pipe and an air bag fixed to the ring-shaped pipe. The lifting force when the pedestrian is supported is the load applied to the training machine by the pedestrian, but when the load increases due to a fall etc., the lifting force is controlled so that it does not increase beyond the input value initially set. Therefore, it is possible to prevent accidents such as sudden lifting when falling. In this way, the pedestrian can practice walking while bearing the load. At that time, the pedestrian can grasp an arbitrary point of the ring-shaped pipe and can change the point appropriately. Further, the air bag can disperse or concentrate the support points of the pedestrian, and the tightening force can be adjusted as desired, so that fatigue can be minimized.

Hereinafter, the human body supporting device of the walking training machine of the present invention will be described in detail.

After that, the opening 17 is fixed. Next, the air bag 18,19,20 by the air bag
Adjust the internal pressure of 14, 15 and 16. At this time, when it is desired to concentrate the support points on the armpit, the internal pressure of the air bag 14 is made higher than the others, and when it is desired to disperse the air bags 14 to the whole, the internal pressure is made substantially equal. The internal pressure control may be performed by the control unit 6. At this time, it is assumed that the lifting setting value desired by the pedestrian has already been input to the control unit 6. When the start switch is turned on in this state, a predetermined lifting force is transmitted from the air cylinder 5 to the pipe 2 from the arm portion 2 and supports the pedestrian through the string 13 and the air bags 14, 15, 16. The pedestrian holds the posture by gripping the pipe 12, but since the pipe has a ring shape, all points are approximately equidistant from the pedestrian, so that it is possible to grip any desired point. it can. For example, as shown in FIG. 1 (b), it is possible to bear part of the weight by hand when grasping in a position where the hand is lowered, and parallel balance is obtained when grasping in a position where the hand is extended forward. It becomes easier and, when grasping with the hand raised, it is possible to practice walking while also performing a hanging motion.

The above-mentioned three points of gripping are shown in FIG. The shape of the pipe 12 can also achieve the purpose.
However, in consideration of gripping at an arbitrary position including an oblique position, the ring-shaped pipe 12 is preferable.
