Armrest Height Adjusting Pin —CS-01

For (With Whom)

People who must attach and detach the armrest every day among several adjustment positions.

Why

Because a wheelchair table for maintaining a seated posture was in use, proper setting was required so that there was no left-right difference in the height of the armrests. On the other hand, in clinical settings where several caregivers are involved in transfer assistance, marks are needed so that the armrest settings do not become inconsistent, and tape used as a mark often peeled off.

How

In interviews with helpers and therapists involved in care, many said it was hard to adjust the armrest by eye each time while keeping watch on the user, whose sitting posture is unstable after a transfer. Because the armrest was of the type that attaches and detaches vertically, we identified the adjustment positions used on a daily basis and made cap-shaped pins matched to the position and diameter of the adjustment holes. TPU was chosen as the material so the pins can be pushed tightly into the holes and do not come off during insertion.

Outcome

In daily care, setting the armrest height became easier, reducing stress for those involved in care. In addition, because the reproducibility of the armrest height setting is efficiently ensured, the risk of the user's sitting posture collapsing due to a setting error, and of accidents while setting the armrest, was also reduced.
