Bottle Opener Kit —DL-18

For (With Whom)

People who find it hard to open the lid of a jar or bottle with one hand, such as people with stroke hemiplegia.

Why

In daily life, we often open jar lids, for example for jam or for side dishes to put on rice. However, with stroke hemiplegia, when one hand cannot be used freely, it can become difficult to hold the jar steady while opening the lid. In particular, the first opening of a lid requires strong holding force, so it is a difficult task with one hand. As a result, people often have to ask someone else to open it. We therefore thought that if there were a self-help device to hold the jar in place, the person could open the jar lid on their own at any time they like, even with one hand, and so we made it. Since jars come in various sizes, it was made to accommodate jars of various sizes.

How

It is intended to be used by people with stroke hemiplegia to hold a jar in place while opening its lid. Place the jar on the self-help device, slide the two parts to match the size of the jar, and clamp the jar. Alternatively, slide the two parts to match the jar size, then insert the jar from above. If the hold is insufficient, slide the two parts until sufficient hold is obtained. After confirming that the jar is held sufficiently, open the lid. (Supplement) It consists of two parts, "Upper" and "Lower."

Outcome

Being able to hold the jar in place also made it possible to do the first opening of the lid.
