Description

Electric rehabilitation bench {ELECTRIC REHABILITATION BENCH}

The present invention relates to an electric rehabilitation bench, and more specifically, to an electric rehabilitation bench that has been improved to allow detailed adjustment of height and angle.

In general, a rehabilitation bench is an auxiliary and training device used for rehabilitation treatment of children with developmental disabilities or cerebral palsy.

These rehabilitation benches are mainly used for the following purposes by manually adjusting the height, front, back, and left and right angles.

First, it is used as a sitting chair to maintain an appropriate sitting posture, as a table for rehabilitation activities, and as a standing auxiliary table that can be held or supported for standing.

In addition, it is used for standing training for standing up from sitting, standing up and sitting training, and is used as a gait training equipment (obstacle) to hit and go over with one foot. In addition, it is used for multiple purposes depending on the purpose and situation of rehabilitation treatment. do.

In this way, it is essential for the rehabilitation bench to adjust the height and angle appropriately in consideration of the functional characteristics and body size of the child's body.

And the rehabilitation bench is also used as a sitting chair.

In other words, it is used as a sitting chair to maintain appropriate sitting posture during rehabilitation treatment. In order to maintain appropriate posture for rehabilitation treatment, the plantar surfaces of both feet are in contact with the ground, the hips and knees are maintained at approximately 90 degrees of flexion while seated, and trunk alignment is required by adjusting the angle of the pelvis (forward or backward tilt).

Specifically, torso safety in a sitting position is ensured only when the soles of both feet are in contact with the ground. If the soles of both feet are floating without touching the ground in a sitting position, it is difficult to maintain the posture due to instability of the trunk.

Additionally, in a sitting position, the knee joint angle is approximately 90 degrees, which is an ideal angle that is physically comfortable.

Additionally, it is possible to maintain appropriate posture (trunk control) by adjusting the angle of the pelvis (forward or backward tilt angle).

In other words, the front and rear angle of the bench can be adjusted by adjusting the angle of the pelvis, which makes it possible to induce correct alignment of the trunk, and by changing the angle of the pelvis in a sitting position, it is possible to maintain correct posture by inducing trunk adjustment.

Additionally, rehabilitation benches are used as tables for activities.

In order to perform rehabilitation activities using hands while sitting, appropriate height and angle adjustment of the table is required.

And the rehabilitation bench is used as a standing support table.

It is used as a support table in front to maintain balance while standing. At this time, when the hands are extended, both palms must be positioned at a distance that can touch the support surface of the table, so proper height and angle adjustment of the table is required.

Additionally, rehabilitation benches are used for standing training.

It is used as standing training equipment, such as standing from sitting and sitting from standing. At this time, training begins with the hip and knee joints maintained at 90 degrees, and the difficulty of the training can be adjusted by adjusting the height and angle of the table.

And it is used as a gait training device (obstacle).

Because it is used as a gait training device to stand on a bench with one foot for gait training, height and angle adjustments are required to adjust the difficulty level.

For such multi-purpose use, detailed height and angle adjustment of the bench is essential. In particular, a function is required to check the current height and angle while a child is sitting on or supporting the bench and immediately adjust it to the appropriate height and angle. do.

However, the benches currently used in medical institutions and clinical settings are configured to manually adjust the height and front/back angle, and the up and down height and front/back angle of the bench can be changed by manually loosening and tightening the levers located on the left and right sides. It is being used (see Figure 11).

However, the conventional rehabilitation bench constructed and operated in this way cannot be precisely adjusted by adjusting the height and angle in a step-by-step (five-step) manner.

If detailed height adjustment is not possible and the soles of your feet float on the ground while sitting, you must use an additional footrest or thick book to adjust the height.

Also, it is impossible to adjust the height and angle while the child is sitting. In other words, when height and angle adjustments were necessary during treatment, it was difficult to frequently get the child off the bench, readjust it, and place it back on, and there were difficulties in continuity of treatment.

In addition, the bench itself was heavy, and the height and angle had to be adjusted each time to match the physical characteristics of the next patient (child), so the physical work intensity of the therapist who manually adjusted it was high.
