Hyappatsu-Hyakuchu (Bell Switch Pusher)

For Whom: For people with limited hand function due to Parkinson's disease and similar conditions, I devised this self-help device so that they can press the switch of the commercially available call bell that the user already has. The images show, in order, a type that can also be pressed with the foot, a standard type, a type that can be used in the bath, and a larger version of the standard type; four types of Hyappatsu-Hyakuchu in total were made this time. The switch uses the accessory that comes with the commercially available bell. It is printed on a 3D printer using PLA resin. The switch is attached with elastic double-sided tape. Note: As a precaution, remove sharp edges of the self-help device with sandpaper or similar to prevent the user from getting injured.
