first-aid kit
A box or case containing basic medical supplies for emergency treatment.
救急箱はいつも手の届くところに置いてある。
The first-aid kit is always kept within reach.
Since the child fell down, I quickly opened the first-aid kit.
I put new bandages in the first-aid kit.
I took the disinfectant out of the first-aid kit and applied it to the wound.
