Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automatic suspension device for gait training, and more particularly to an automatic suspension device for gait training that is convenient for wheelchair patients.

[Background technology] Conventionally, for patients who require gait training,
With the help of a PT (occupational therapist) or nurse, training begins with ramp training, then parallel bars, a walker, and training.
Gradual training using crutches was common. Training has also been carried out by using buoyancy in Hubbard tanks and gait training pools to reduce weight bearing. However, in the case of patients who are completely unable to walk or are close to being unable to walk, neither method is effective.
The problem was that it required a large number of people, including PTs, and time. Additionally, due to the limited number of medical staff, there were problems such as insufficient training.

Therefore, an automatic suspension device for gait training has been developed that allows gait training to be performed with only a small amount of muscle strength and does not require much human labor. This automatic suspension device for gait training has a main body that is the basic axis of the device, and can rotate 360° horizontally and up and down vertically.
A lifting arm section that is attached horizontally to the main body so that it can move 30 degrees, and a suspension section that is attached to the tip of the lifting arm section that maintains the patient's standing position.
A load sensor such as a load cell that detects the load weight applied to the suspension section, an air cylinder that generates the lifting force for the lifting arm section, and an air cylinder that is controlled so that the lifting force is a value that corresponds to the patient's load. , a control section that adjusts the lifting force when a change in the patient's load is detected by the weight sensor.

In the above configuration, the suspension section is connected to the patient (weight 50
Kg), and then input a lifting command value, for example, 80% of the patient's load, via the input section.
The control unit controls the air cylinder based on the input lifting command value, and adjusts the pressure inside the air cylinder so that the lifting force is 40 kg when the patient puts his entire weight on it. At this time, for example, a patient weighing 50 kg is suspended at 40 kg via the suspension section and the lifting arm section, and the remaining 10 kg is supported by the patient himself. After confirming that the patient's standing position is completely maintained by the lifting arm section and suspension section, gait training begins.
The lifting arm portion rotates following the patient's walk. On the other hand, the weight load applied to the lifting arm during walking training is detected by a weight sensor, and when the weight load increases, the lifting force is controlled to increase accordingly. In this way, the device allows walking training while reducing the weight load on the ground even when it is impossible to maintain a standing position at all. The weight load on this ground surface can be freely set to 1/2, 1/3, or 1/10 of the body weight by adjusting the lifting command value. In this way, by using the device to maintain the patient's standing position and control the weight load, the device can perform gait training with only a small amount of muscle strength, and does not require a large amount of human labor. We were able to realize this.

[Problem that the invention attempts to solve]

However, according to the conventional automatic suspension device for gait training, it is difficult for a patient who uses a wheelchair to reach the suspension part 3 to put away the wheelchair.
It may interfere with walking training.

[Means for solving problems]

The present invention has been developed in view of the above, and is an automatic suspension device for gait training in which a part of the handrail is provided with a recess for accommodating the wheelchair, in order to prevent wheelchair patients from getting in the way of gait training. I will provide a.

Hereinafter, the automatic suspension device for gait training according to the present invention will be described in detail.

〔Example〕

FIG. 1 shows an automatic suspension device for walking training to which the present invention is applied. This automatic suspension device for walking training has a main body 1 which is the basic axis of the device, and can rotate 360° horizontally and up and down vertically.
A lifting arm part 2 is attached horizontally to the main body 1 so that it can move by 30 degrees, and a lifting arm part 2
A suspension section 3 attached to the tip of the suspension section 3 to maintain the patient's standing position, a weight sensor 4 that detects the load weight applied to the suspension section 3, an air cylinder 5 that generates lifting force, and a lifting command value for the lifting arm section 2. It consists of an input section (not shown) for inputting information, a control section 6 for controlling the air cylinder 5, etc., and a training handrail 7.

FIGS. 2a and 2b show an embodiment of the present invention, in which a patient using wheelchair X can operate and use the device by himself. Remote control: details omitted) and
It consists of a training handrail 7 having a recess 7e in which the wheelchair X is accommodated. Others are the same as in FIG. 1, and their explanation will be omitted.

In the above configuration, the patient in the wheelchair operates the remote control input device 17 to lower the suspension section 3 to the height of the wheelchair
(It is also possible to have a configuration in which it is tilted downward.) Attach the suspension section 3 and lift the suspension arm section 2 and suspension section 3.
After confirming that your body is properly suspended, stand up quietly. As shown in FIG. 2b, the wheelchair X is placed in the recess 7e of the training handrail 7, and walking training is started. After completing the training, the patient similarly pulls out wheelchair X, moves it to a predetermined position, and sits down. After sitting down on the wheelchair X, the user operates the remote control input device 17 to release the suspension and remove the suspension part 3. In this way, a patient in a wheelchair can use the device without injuring the hands of others. Therefore, the patient can freely perform gait training whenever he or she wants, increasing spontaneity.

[Effect of idea]

As explained above, according to the automatic suspension device for gait training of the present invention, a recess for accommodating a wheelchair is provided in a part of the handrail, so that the wheelchair does not interfere with gait training for wheelchair patients. I can do it.
