Ringer Balloon / Ringer Drone

Ringer Drone / Ringer Drone for children who want to romp around
We can see many children in the hospital.
Whenever they are on a drip, they suffer the inconvenience of ringer. It makes the children feel extremely uncomfortable sad because the ringer ties the children who love to have fun to the ringer.
It’s hard for the children to draw the ringer taller than their height. The uneven ground can be the biggest obstacle to moving.
In order to feel comfortable and play around freely, I will introduce the ringer drone, making it easy to move around.
