The Knightingale ATDF Project (A resolution to Bedsores)
Team Members • Anthony Spencer • Senior at BMHS • Antonia Gruning • Senior at TMHS • Ali Welch • Junior at CHS http://www.cs.uml.edu/teams-academy/index.php/Student/ClamHome
Requirements/Constraints • Safety (Must have NO sharp edges) • Construction time (3 months) • Battery that can be rechargeable and long lasting (approx 12 hours). • Cost (only have $150) • Durability and Efficiency. • Clean-looking and presentable • Must be easy to control • Size • Weight • Must keep the spine strait at all times
Client • Our client’s name is Mrs. Gibbs. • Mrs. Gibbs awhile back went into a surgery to get her stomach stapled. When she came out, she was paralyzed from the waist down. • The main problem Mrs. Gibbs faces and has faced is bedsores. • Statement of Need: Our client needs her wheelchair to prevent bedsores instead of causing them.
On the Market • The closest product to preventing pressure sores caused by wheelchairs are the type of products made for massage chairs. None specifically for curing pressure sores. • None have been made readily for the wheelchair, and it is hard to find one that can fit. • Many do not have batteries, thus eliminating the movement done by a wheelchair. • Another product that could be used, is a gel pad seat made for wheelchairs.
The Magnetic Ball Plan • The idea behind this design is to increase blood circulation in our client's butt as she is sitting in her wheelchair. • There would be metal balls under the gel pad, with electromagnetic walls on either side. • We are going to shift the North and South poles, causing the metal balls to move back and forth underneath the gel pad. • This will then stimulate blood circulation, and stop the blood veins from being blocked up.
Popcorn Machine • Another method was based off the idea of a popcorn machine. • The purpose of this method, was to alleviate different pressure points, in a random order. • The randomness would eliminate the problem of consistent pressure.
Popcorn Machine (cont.) • Two magnetic fields would be used, one on top and one on the bottom of the device. • Metal balls would be pulled to opposing fields at random. Thus, creating a popcorn like effect.
Gel Pad • This design would essentially be a massage pad for a chair covered by a gel pad layer to relieve pressure. • It would be attached to the seat and back of the chair with straps that clasp under the seat and behind the back of the chair. • The battery would need to hang off of one of the sides of the seat or to be somehow attached to the bottom of the chair.
Pros and Cons • PROS • Gel Pad creates comfort, and spine secure placement • Popcorn machine creates random pressure relief • Magnetic balls increase blood flow and circulation • CONS • Gel Pad’s thickness, as well as already on the market • Popcorn machine requires a high voltage • Magnetic Balls is extremely costly as well as a high power necessity for magnetic field to function
Final Design • An electro-mechanical actuator is the least expensive linear actuator that can be controlled be electronics. • We will redesign a premade massage pad for a chair to use less drastic motion in order to shift the spine best.
Parts List • 12 Volt Battery • Gel Pad (bike) • Massage Seat • Resistors • Transformers • Relays • Touch Sensors • Remote • Wheelchair! 3D Design Coming Soon!
