Sound Soothing Wheelchair

Brown University

Problem

11% of the United States elder population, 65 years and older, are diagnosed with dementia. Sometimes these patients can go into a state of aggression, due to agitation, which can lead to violence towards themselves or their caregiver. What is currently on the market to help relieve patients of their agitation mainly consists of pharmaceutical drugs and advanced wheelchairs. Some patients can not move on their own, so they stay in the wheelchair all day. With the wheelchairs currently on the market, patients can experience discomfort, due to lack of durability.

Solution

A wheelchair was created to soothe dementia patients, non-pharmaceutically. I decided to research wheelchairs utilized for dementia patients. After I looked at what was on the market, I decided to design a wheelchair that would help to maximize their comfort level. For my thesis I created a wheelchair that will be equipped with musical therapy, automated rocking, and increased comfort levels. I wanted to add these features to the wheelchair because in my research, I learned that the brain of dementia patients seem to regress in life. Therefore, I decided to try and mimic ways in which people sooth babies when they get irritated.

Design Features

Cushion

  • Wool: Elastic material and helps to regulate body temperature

  • Nylon: Its resistance to absorb moisture allows the material to be easy to clean

  • Gel-based memory foam: Helps regulate body temperature and increases air circulation

Music Therapy

Music therapy will be administered through bluetooth speakers within the headrest. The music will be controlled through an app that only the caregivers can control. Each patient will have a personal playlist.

Automatic Rocking

Automatic rocking will be executed by using a camshaft to create an up/down motion of the entire wheelchair. A camshaft is used because the minimal amount of joints causes less friction, and they have an ability to lift heavy weights.
